Technical Field

The present application relates to the field of communications, and in particular, to a data transmission method and apparatus.

Background

In recent years, with the progress of urbanization, urban population and urban scale are continuously enlarged, so that population flow is more and more frequent, and great challenges are brought to urban public security management. In order to better realize efficient management of cities, the public accommodation industry generally arranges a city dynamic video monitoring system in the city. The urban dynamic video monitoring system is a large-scale comprehensive monitoring system covering the whole city, the video monitoring coverage is very wide, and therefore the monitoring access points of one city are very many. On the other hand, since video is transmitted, the requirement for bandwidth is very high, requiring transmission bandwidth of several or even several tens of megabits. Meanwhile, networking is needed among different areas or cities, so that the network is also complicated.

At present, with the large-scale deployment of the fourth generation (4th generation, 4G) cellular network, the 4G cellular network and other cellular networks can provide a transmission rate of several hundred megabytes, so that the video monitoring transmission by adopting the cellular network is applied to a certain extent. Meanwhile, the video monitoring based on the cellular network has the characteristics of simple deployment, low cost, wide coverage range and the like.

However, the existing transmission mode of video monitoring data is usually that the video camera is used for acquisition and transmission, and when a safety event or other emergency occurs, the video monitoring data is limited by the bandwidth of the existing wireless network, so that the video monitoring data cannot be transmitted efficiently and flexibly.

Disclosure of Invention

The embodiment of the application provides a data transmission method and device, which are used for realizing efficient and flexible transmission of video monitoring data under the condition of abnormal safety events.

A first aspect of an embodiment of the present application provides a data transmission method, including:

the data transmission method is applied to a video monitoring system consisting of a camera, a base station and a monitoring center.

Step 1, the base station receives trigger information, wherein the trigger information is request information generated under the condition that a trigger event is met.

In this embodiment, the trigger information may be generated by a camera or a monitoring center in the video monitoring system when the trigger is satisfied, and specifically may include a priority transmission request, a serial number identifier of the second camera, a serial number identifier of the first camera, a serial number identifier of the target area, or an instruction command.

And 2, the base station distributes preset transmission information to the first camera according to the trigger information and sends the preset transmission information to the first camera.

In this embodiment, the preset transmission information includes a transmission priority, a preset transmission channel, and a preset transmission bandwidth of the first camera; or, the preset transmission information includes the preset transmission channel and the preset transmission bandwidth. The transmission priority of the first camera is determined by the base station according to the quality of the preset transmission channel and the level of a preset safety event in the video to be transmitted.

It is to be understood that the predetermined transmission channel and the predetermined transmission bandwidth are dedicated to transmitting video data in which a predetermined security event or abnormal event occurs. And the transmission priority of the first camera can be determined by the base station according to the security level of the preset security event or abnormal event and/or the channel quality between the current transmission link between the camera and the base station. For example, if the security level of the preset security event in the first video data is the first level, the base station may adjust the transmission priority of the first camera to the highest level. Or, when the security level of the preset security event in the first video data is the third level and the quality of the transmission link channel between the first camera and the base station is poor, the base station may maintain the transmission priority of the first camera as it is.

And 3, the base station receives the first video data sent by the first camera by utilizing the preset transmission information, wherein the first video data is the video data collected by the first camera.

And 4, the base station sends the first video data to a monitoring center.

In the technical scheme provided by the embodiment of the application, when a trigger event occurs, the base station allocates preset transmission information for the first camera of the data to be transmitted, so that the first camera can rapidly transmit the first video data of the first camera by using the preset transmission information, and efficient and flexible transmission of video monitoring data is realized.

Optionally, in this embodiment of the present application, the generation process of the trigger information includes multiple possible implementation manners, which are specifically as follows:

based on the first aspect of the embodiment of the present application, in an optional implementation manner of the embodiment of the present application, the trigger information includes a priority transmission request generated by the first camera when a preset security event or an abnormal event is identified for the first video data; wherein, the step 1 specifically comprises: and the base station receives a priority transmission request sent by the first camera.

Specifically, the preset security incident or abnormal incident may include a thief, a cheater, a criminal pursuit, a robbery, a group violence incident, a suicide incident or other criminal incidents registered in the video data, which is only a part of examples, and the specific scope is determined by the user, which is not limited herein. Meanwhile, the first camera can identify the video data by adopting at least one of face identification, gait identification or dynamic posture identification.

In this embodiment, the first camera includes an identification module, which can identify in real time whether the video data collected by the first camera includes a preset security event or an abnormal event, so that the video data where the preset security event or the abnormal event occurs can be reported in time, and the city security is effectively ensured.

Based on the first aspect of the embodiment of the present application, in an optional implementation manner of the embodiment of the present application, the trigger information includes a second camera identifier generated when the monitoring center identifies a preset security event or an abnormal event for second video data acquired by a second camera; wherein, the step 1 specifically comprises: the base station receives the serial number identification of the second camera sent by the monitoring center; then, the step 2 specifically comprises: the base station searches the first camera according to the serial number identification of the second camera, wherein the second camera and the first camera are mutually related cameras; the base station distributes the preset transmission information to the first camera.

Specifically, the association relationship between the first camera and the second camera may be a location association or a number identification association. For example, there is an overlapping or complementary place between the shooting range of the first camera and the shooting range of the second camera, or the distance between the serial number identifier of the first camera and the serial number identifier of the second camera is within a preset range. In one example, the first camera is located near the store a, the second camera is located near the store B, and the store a and the store B are directly opposite to each other, that is, the first camera and the second camera can both capture images between the range of the store a and the range of the store B, only the video captured by the first camera is captured at the angle of the store a, and the video captured by the second camera is captured at the angle of the store B, and the video data of the two cameras can supplement the images that are not captured by the two cameras. Therefore, the first camera and the second camera are associated cameras. In another example, the number identifier of the first camera is 01, the identifier of the second camera is 03, and the preset range of the distance between the number identifiers is less than 10, then the first camera and the second camera are associated cameras.

The technical scheme of the embodiment can be applied to a scene that the camera does not comprise an identification module or the monitoring center repeatedly identifies the video data, so that the monitoring center informs the base station to acquire the video data acquired by the camera which is in mutual association with the second camera, thereby supplementing the video data which is not completely shot in the second video data, leading a user to clearly know the whole process of an event and improving the effectiveness of the video data.

It can be understood that the base station may notify the first camera of the preset transmission information in a manner of sending a separate indication information to the first camera; the base station may also notify the first camera of the preset transmission information in a manner that other information instructions carry the preset transmission information, and a specific manner is not limited here.

204. The first camera sends the first video data to the base station by using the preset transmission information, wherein the first video data is the video data collected by the first camera.

After the first camera acquires the preset transmission information, the first camera sends the first video data to the base station by using a preset transmission channel and a preset transmission bandwidth in the preset transmission information or by using the preset transmission channel, the preset transmission bandwidth and a transmission priority.

205. And the base station sends the first video data to a monitoring center.

The base station forwards the first video data to the monitoring center after receiving the first video data.

Optionally, in the video monitoring system, a plurality of cameras may exist in the same time period to send video data with a preset security event or an abnormal event, that is, the base station may also receive third video data sent by a third camera using the preset transmission information, and at this time, the base station may perform joint processing on the third video data and the first video data to generate to-be-transmitted video data; and then the base station sends the video data to be transmitted to a monitoring center. It is understood that the third camera is a camera associated with the first camera.

Optionally, in practical application, the base station may further count an idle traffic time period of a cell in which the base station is located, and then instruct a camera connected to the base station to transmit video data acquired by the base station in the idle traffic time period when a trigger event does not occur in the video system. Therefore, the camera does not transmit the acquired video data immediately, but transmits the normal video data by using the idle flow time period, so that the transmission speed can be increased, the resource consumption in the busy time period in the cell can be saved, and the influence on the communication quality of the base in the busy time period is reduced.

In this embodiment, when a trigger event occurs in the video monitoring system, the base station may allocate the preset transmission information dedicated to sending the video data to the first camera of the video data to be transmitted, so that the first camera may quickly send the first video data to the base station, thereby implementing efficient and flexible transmission of the video monitoring data. Meanwhile, the base station performs joint processing on the video data sent by the plurality of cameras to generate the whole video data, so that the data volume of the video data can be reduced, and the transmission efficiency is improved.

The following describes the scheme in the embodiment of the present application in different application scenarios:

firstly, the first camera identifies a preset safety event or an abnormal event for the first video data acquired by the first camera.

As shown in fig. 3, an embodiment of a data transmission method in the embodiment of the present application includes:

301. the base station determines the idle traffic time period of the cell in which the base station is located.

And the base station counts idle flow time periods in the cell according to the historical service flow conditions of the cell in which the base station is positioned. Specifically, the base station may first determine a statistical duration, such as a day, a week, a month, or a year; then the base station counts the service flow time distribution of the local cell in the counting time length, thereby determining the idle flow time period in the cell. Such as which time period has the lowest traffic flow in one day, which day of the week has the lowest traffic flow, which day of the month has the lowest traffic flow, or which month of the year has the lowest traffic flow, etc. The specific statistical duration may be determined by the base station according to an actual situation, and is not limited herein.

302. And the base station sends the information of the idle flow time period to a camera in the cell and indicates the camera to send normal video data in the idle flow time period, wherein the camera in the cell comprises the first camera.

After acquiring the idle flow time period of the cell, the base station sends the idle flow time period to all cameras in the cell in the form of indication information, and indicates all cameras in the cell to send normal video data in the idle flow time period. In this embodiment, the first camera is a camera in a cell where the base station is located.

303. The first camera collects first video data.

The first camera collects first video data in real time in the using process.

It is understood that there is no fixed time sequence limit between step 301 and steps 302 and 303.

304. The first camera identifies whether a preset security event or an abnormal event occurs in the first video data, if so, step 306 is executed; if not, go to step 305.

After the first video data are collected by the first camera, the first video data are identified and analyzed, and whether a preset safety event or an abnormal event occurs in the first video data is judged. If the preset security event or the abnormal event occurs in the first video data, execute step 306; if the predetermined security event or exception event does not occur in the first video data, step 305 is executed.

It is understood that the first camera may adopt the following method when performing recognition analysis on the first video data:

in one possible implementation manner, the first camera determines whether a thief, a cheater or a criminal for catching a criminal or the like registered in a case appears in the first video data by using a face recognition method or a gait recognition method;

in another possible implementation manner, the first camera determines whether the first video data includes robbery, group violence, suicide or theft by using methods such as dynamic gesture recognition.

In this embodiment, the preset security event or the abnormal event may be classified according to security level, for example, events such as robbery, group violence event, etc. may be set to a first level; events such as theft may be set to a second level. In this embodiment, the first level is higher than the second level.

305. The first camera buffers the first video data and sends the first video data to the base station in the idle flow time period.

If the first camera does not recognize the preset security event or abnormal event from the first video data, the first camera caches the first video data, and then sends the first video data to the base station in the idle traffic time period of the cell.

306. The first camera sends a priority transmission request to the base station.

If the first camera identifies the preset security event or the abnormal event from the first video data, the first camera sends a priority transmission request to the base station.

Optionally, the priority transmission request may carry key feature data about a security event or an abnormal event in the first video data. Therefore, the base station can identify the first video data again according to the key characteristic data and confirm whether the first video data has a security event or an abnormal event, so that the accuracy of reporting the video data is effectively controlled.

307. The base station distributes preset transmission information for the first camera.

And after receiving the priority transmission request, the base station distributes preset transmission information to the first camera.

In this embodiment, the preset transmission information may include the following possible implementation manners:

in a possible implementation manner, the preset transmission information includes a transmission priority, a preset transmission channel, and a preset transmission bandwidth of the first camera.

308. The base station sends the preset transmission information to the first camera.

309. The first camera sends the first video data to the base station by using the preset transmission information, and the first video data carries the serial number identification of the first camera.

And after receiving the preset transmission information, the first camera sends the first video data to the base station by using the preset transmission information. The first video data may carry a serial number identifier of the first camera.

310. The base station analyzes the first video data to obtain the serial number identification of the first camera.

After the base station receives the first video data, the base station analyzes the first video data to obtain the serial number identifier of the first camera.

It can be understood that the serial number identifier of the first camera may also be carried in the priority transmission request sent by the first camera, so that the base station may obtain the serial number identifier of the first camera from the priority transmission request.

311. And the base station searches for a third camera according to the serial number identification of the first camera, wherein the third camera and the first camera are related cameras.

After acquiring the serial number identifier of the first camera, the base station may find a third camera associated with the first camera according to the serial number identifier of the first camera.

It is understood that the association relationship between the first camera and the third camera may be a location association and/or a number identification association. For example, there is an overlapping or complementary place between the shooting range of the first camera and the shooting range of the third camera, or the distance between the serial number identifier of the first camera and the serial number identifier of the third camera is within a preset range. In one example, the first camera is located near the store a, the third camera is located near the store B, and the store a and the store B are directly opposite to each other, that is, the first camera and the third camera can both capture images between the range of the store a and the range of the store B, only the video captured by the first camera is captured at the angle of the store a, and the video captured by the third camera is captured at the angle of the store B, and the video data of the two cameras can supplement the images that are not captured by the two cameras. Therefore, the first camera and the third camera are associated cameras. In another example, the number identifier of the first camera is 01, the identifier of the third camera is 03, and the preset range of the distance between the number identifiers is less than 10, then the first camera and the third camera are associated cameras.

312. The base station distributes the preset transmission information for the third camera and sends the preset transmission information to the third camera.

After the base station acquires the third camera associated with the first camera, in order to supplement the integrity of the video data, the base station notifies the third base station to send the third video data acquired by the third base station, so that the base station allocates the same preset transmission information as that of the first camera to the third camera. And then sending the preset transmission information to the third camera. Similarly, when the base station sends the preset transmission information to the third camera, the base station may notify the third camera of the preset transmission information in a manner of sending separate indication information to the third camera; the base station may also notify the third camera of the preset transmission information in a manner that other information instructions carry the preset transmission information, and a specific manner is not limited here.

313. And the third camera sends third video data to the base station by using the preset transmission information.

After the third camera acquires the preset transmission information, the third camera sends the third video data to the base station by using the preset transmission information.

314. And the base station processes the first video data and the third video data to obtain video data to be transmitted.

After the base station receives the first video data and the third video data, the base station performs joint processing on the first video data and the third video data to generate the video data to be transmitted.

It can be understood that the method for the base station to jointly process the first video data and the third video data includes the following ways:

In another possible implementation manner, the base station combines a part of the first video data and a part of the third video data to generate a new complete video, and the new video serves as the to-be-transmitted video data. For example, the first video data has a duration of 2 minutes, and the third video data has a duration of 3 minutes; and then the base station cuts out the video data of 1 minute duration related to the preset safety event in the first video data, cuts out the video data of 2 minutes duration related to the preset safety event in the third video data, and then combines the two parts to generate the video data of 3 minutes duration.

In another possible implementation manner, the base station directly combines the first video data and the third video data to generate the to-be-transmitted video data. For example, the first video data has a duration of 2 minutes, and the third video data has a duration of 3 minutes; and then the base station combines the first video data and the third video data to generate video data with the duration of 5 minutes.

315. And the base station sends the video data to be transmitted to a monitoring center.

The base station sends the video data to be transmitted to the monitoring center so that the monitoring center displays the video data to be transmitted in a man-machine interface mode.

In this embodiment, when the first camera recognizes that the video data acquired by the first camera has the security event or the abnormal event, the first camera actively sends the priority transmission request to the base station, so that the base station allocates a transmission resource dedicated to transmitting the video data having the security event or the abnormal event to the base station, and the video data can be transmitted efficiently and flexibly, thereby improving the effectiveness of the urban security and security management. Meanwhile, the base station jointly processes the video data collected by the cameras and then sends the video data to the monitoring center, so that the integrity of the video data can be effectively improved, the transmission quantity of the video data is reduced, and the transmission efficiency is improved.

And secondly, the monitoring center identifies a preset safety event or an abnormal event for second video data acquired by a second camera.

It can be understood that each camera of the video monitoring center in the scene can be a camera without a video identification function, so that the cost of the image acquisition equipment can be saved under the condition of ensuring that the video monitoring is effective. Meanwhile, each camera of the video monitoring center can also be a camera with a video identification function in the scene, so that the monitoring center can detect video data again, and the accuracy of video monitoring is improved.

The monitoring center can also find the cell where the second camera is located according to the serial number identifier of the second camera, then determine the base station controlling the access of the second camera, and then directly send the serial number identifier of the second camera to the base station. Therefore, the signaling interaction between the monitoring center and the base station can be reduced, and the consumption of network resources is reduced.

403. The base station searches the first camera according to the serial number identification of the second camera, and the first camera and the second camera are related cameras.

After the base station receives the serial number identification of the second camera, the base station searches for a first camera which is associated with the second camera according to the serial number identification of the second camera. It is understood that the association relationship between the first camera and the second camera may be a location association and/or a number identification association. For example, there is an overlapping or complementary place between the shooting range of the first camera and the shooting range of the second camera, or the distance between the serial number identifier of the first camera and the serial number identifier of the second camera is within a preset range. In one example, the first camera is located near the store a, the second camera is located near the store B, and the store a and the store B are directly opposite to each other, that is, the first camera and the second camera can both capture images between the range of the store a and the range of the store B, only the video captured by the first camera is captured at the angle of the store a, and the video captured by the second camera is captured at the angle of the store B, and the video data of the two cameras can supplement the images that are not captured by the two cameras. Therefore, the first camera and the second camera are associated cameras. In another example, the number identifier of the first camera is 01, the identifier of the second camera is 03, and the preset range of the distance between the number identifiers is less than 10, then the first camera and the second camera are associated cameras.

Optionally, the base station may notify the preset transmission information to the first camera by sending separate indication information to the first camera; the base station may also notify the first camera of the preset transmission information in a manner that other information instructions carry the preset transmission information, and a specific manner is not limited here.

405. The first camera sends the first video data to the base station by using the preset transmission information, and the first video data is collected by the first camera.

The first camera collects the first video data during working, analyzes the indication information to obtain the preset transmission information after receiving the indication information for indicating the preset transmission information, and then sends the first video data to the base station by utilizing the preset transmission information.

406. And the base station sends the first video data to the monitoring center.

The base station sends the first video data to the monitoring center so that the monitoring center displays the first video data in a man-machine interface mode.

It is to be understood that the camera head of the camera head correlated to the second camera head may further include the third camera head, and the third camera head may send the third video data collected by the third camera head to the base station in the same manner as the first camera head. After receiving the third video data, the base station may perform joint processing on the third video data and the first video data to generate video data to be transmitted, and then send the video data to be transmitted to the monitoring center. The specific implementation is the same as step 312 to step 315, and is not described herein again.

It will be appreciated that the embodiment shown in fig. 4 and the embodiment shown in fig. 3 may complement each other, i.e. the monitoring center may continue to identify the predetermined security event or abnormal event that is not identified by the second camera. Of course, after the second camera recognizes the preset security event or the abnormal event, the monitoring center performs recognition and detection again, and if both recognize the preset security event or the abnormal event, the schemes shown in fig. 3 and 4 may be executed at the same time, or one of the schemes may be selected optionally.

Meanwhile, the base station jointly processes the video data collected by the cameras and then sends the video data to the monitoring center, so that the integrity of the video data can be effectively improved, the transmission quantity of the video data is reduced, and the transmission efficiency is improved.

And thirdly, the monitoring center acquires a monitoring instruction, and the monitoring instruction is used for indicating the monitoring center to acquire the video data of the camera in the target area.

As shown in fig. 5, another embodiment of the data transmission method in the embodiment of the present application includes:

501. the monitoring center obtains a monitoring instruction, and the monitoring instruction is used for indicating the monitoring center to obtain video data of the camera in the target area.

The monitoring center can receive a monitoring instruction sent by a third party, and the monitoring instruction is used for indicating the monitoring center to acquire video data acquired by a camera in a target area.

For example, if people flow in a store at weekends is large, and the store needs to monitor events at various places in real time, the monitoring center needs to acquire video data in the store, and at this time, a monitoring instruction received by the monitoring center is to acquire video data in the store.

502. The monitoring center sends the number identification of the target area to the base station.

503. And the base station searches the first camera according to the serial number identifier of the target area.

After the base station receives the serial number identification of the target area, the base station searches for the first camera in the target area.

In this embodiment, according to the difference of the number identifier of the target area sent by the monitoring center, the execution mode of the base station is also different, which is specifically as follows:

in a possible implementation manner, if the monitoring center sends the number identifier of the target area to all base stations in the video monitoring system, each base station needs to select and determine whether the target area is included in a cell where the base station is located, if so, the base station searches for a camera within the range of the target area as the first camera, and if not, the base station does not respond.

In another possible implementation manner, if the monitoring center sends the serial number identifier of the target area to the base station corresponding to the target area, the base station may directly search for the camera in the target area as the first camera.

Optionally, the monitoring center may store the number identifiers of all the cameras, the area number identifiers, and the relationship table between the base stations, and after receiving the monitoring instruction, the monitoring center may directly determine the number identifier of the camera that needs to upload the video data, and then send the number of the camera to the base station, and instruct the base station to allocate the preset transmission information to the camera. Therefore, the processing steps of the base station can be greatly reduced, and the data transmission efficiency is improved.

504. The base station distributes preset transmission information for the first camera and sends the preset transmission information to the first camera.

The base station distributes preset transmission information for the first camera and sends the preset transmission information to the first camera in an indication information mode.

It can be understood that in the embodiments shown in fig. 4 and fig. 5, the base station may also identify an idle traffic time period of the cell in which the base station is located, notify each camera accessing the base station, and instruct each camera to upload normal video data in the idle traffic time period when acquiring the normal video data.

Meanwhile, after the base station identifies the idle traffic time period of the cell where the base station is located, when the base station does not receive the request information sent by the camera or the monitoring center, the idle traffic time period can be used as preset transmission information to be sent to the camera within the scope of the base station, and therefore the camera can upload video data by using the idle traffic time period.

In this embodiment, after receiving the monitoring instruction of the third party, the monitoring center instructs the base station to acquire the video data of the relevant camera, so that the base station allocates a transmission resource dedicated to transmitting the video data with a security event or an abnormal event to the relevant camera, and it is ensured that the video data can be efficiently and flexibly transmitted, thereby improving the effectiveness of the urban security and security management.
