Description

System with information for changing buses, stations and centers

Technical field

The present invention relates to the technical field of bus system information exchange, in particular to a bus, station, and system with information exchange. The system can provide the center and users with information on the bus and station. Background technique

In recent years, there have been many information collection and release technologies on public transportation systems, especially buses and stations. In current bus services, through GPS, mobile communication systems, image processing and other technologies, centers and passengers can know the location, route, estimated time of arrival, and traffic conditions on the road.

For example, a Chinese patent (01235755.3), Electronic Bus Stops, describes an electronic bus stop installed at a station. Through the Global Positioning System (GPS) and Global System for Mobile Communications (GSM), transportation centers and users can be provided with bus operating locations. A Japanese patent (11-31295) detects the information of the road surface by installing a camera on the car. Another Japanese patent (2003-16587) uses GPS to calculate the estimated time of bus arrival. They publish bus information on the Internet on some lines, including timetables, current bus locations, bus types (with or without stairs to facilitate wheelchair users). At the same time, another Japanese patent (P2003-6784A) introduced a bus concept that dynamically adjusts the schedule operation according to the passenger's riding needs.

However, more information on buses is not available in a timely manner, such as whether the buses are air-conditioned, the congestion on the buses, the ticket prices, and the availability of monthly tickets. Many waiting passengers do not know the status of the several buses that will enter the station, and can only choose the bus that arrives first.

On the other hand, information about the station cannot be provided, such as the congestion of passengers waiting at the station. The center does not know the station information and cannot dynamically adjust the fleet operation to suit the passenger flow at that time.

The traditional bus system that dynamically adjusts and operates according to the passenger's riding needs mainly considers adjusting the fleet operation according to the random needs of users, but does not consider selecting a bus based on the type of bus and the current operating conditions. On the other side, when a passenger transfers from a bus to another vehicle, they have to estimate the estimated time of arrival of an optional bus to the transfer point, find the timetable of other vehicles and the current operating conditions. It is obviously inconvenient to judge and choose the method that is most suitable for them. Summary of the invention The object of the present invention is to provide a bus, station and center system with information exchange. The bus can collect and send bus information to the center, including congestion status, bus type, toll information, etc., and then receive it from the center, including Information on bus fleets and stations along the line.

Another object of the present invention is to provide a station, which can not only display information such as the congestion status, the type of the bus, the bulletin, etc., on the electronic station board on the electronic station board, but also collect information at the station. In addition, stations can send messages to user terminals.

Another object of the present invention is to provide a bus fleet management function that can meet the specific requirements of elderly and disabled passengers, such as whether the type of the bus has a step, or whether the bus can carry wheelchair passengers. This management function can also provide passengers with sufficient information to help them easily transfer from the bus to other transportation tools at the interchange station.

A bus and station system with an information exchange function according to the present invention includes data acquisition, communication, signal processing, and display equipment to exchange information between the bus and the station with a user, such as the congestion on the bus, and the type of bus, Charge information, and the congestion of the station. It is characterized in that the buses and stations send data to the center. After the center processes the data, it converts it into a certain data format and sends it to the corresponding station's electronic station sign, bus display, or personal terminal. The data collected by buses and stations include images taken by cameras, congestion, bus types, fare information, and whether passengers with disabilities are on board. The format of the data varies for different terminals.

The technical solution of the present invention is as follows:-A bus, station and center system with information exchange, including a bus, station and center. The bus detects the information in the car and communicates with the outside world wirelessly for communication with the center and through the center and the station. Exchange of information

The station detects the station information, sends information to the outside, receives information about the approaching bus, and displays the information for exchanging information with the center and the bus through the center;

The center receives information from buses and stations, stores the information, converts the information according to the type of information, and sends the information to the buses and stations.

The bus information includes a crowded condition of passengers in the vehicle.

The station information includes a crowded condition of passengers waiting at the station. According to the above system for buses, stations and centers with information exchange, the buses include a detector, an information processor, a display, and a transceiver. The detector is used to detect the congestion of passengers in the car. The information processor is used to process the data collected by the detector and the data sent from the center. The display is used to display the information sent from the center. The center receives signals, and each bus is assigned a number for identification do not.

The camera captures the image of the interior of the car, which can monitor the situation inside the car and detect the congestion. In order to overcome the overlapping problem, several cameras can be installed at different positions in the car to shoot from different angles. Crowd information can also be gathered by installing sensors on the seat. The information processor processes the information collected by the detector. Congestion information can be calculated from it. The display shows the information sent from the center, including the distance between the bus and the buses ahead, the congestion status of the front bus, and the congestion status of the front to the station. The transceiver sends signals to and receives signals from the center. Each bus is assigned a number for easy identification by the center. In networks that support packet switching, this number can be an Internet Protocol (IP) address.

According to the above system of buses, stations, and centers with information exchange, the stations include electronic station signs, detectors, information processors, and transceivers. The electronic stop sign is used to display the information of approaching the bus, the detector is used to detect the congestion of passengers waiting at the station, the information processor is used to process the data collected by the detector and the data sent from the center, and the transceiver is used to transmit signals to the center and from The center receives signals, and each station is assigned a number for identification.

The electronic stop sign displays information about the bus that is about to enter the station, including the congestion on the bus, the type of bus, toll information, operating location, estimated arrival time, transfer information, etc. The camera takes an image of the station. The congestion of passengers waiting at the station can be detected by cameras. The information processor processes the data sent from the detector, such as the image from the camera, and the data received from the center. The transceiver sends signals to and receives signals from the center. Each station is assigned a number for easy identification by the center. In networks that support packet switching, this number can be an Internet Protocol (IP) address.

According to the above-mentioned system for information exchange of buses, stations, and a center, the center includes a management server, a display, and a transceiver. The management server receives, stores, converts and sends bus and station data, including congestion status, bus type, fare information, and whether passengers with disabilities are on board. Monitors monitor images of buses and stations through images returned by cameras. The transceiver receives signals from buses and stations and sends signals to buses, stations and other

'Other users. '

According to the above-mentioned system for information exchange of buses, stations, and centers, the second type of transceiver is included, which wirelessly communicates with the personal terminals of passengers near the stations, which is different from the first type of wireless communication with the center. · It can communicate with the terminal in a limited range near the station. It has the ability to send the information sent from the center to the station to the terminal, to send the display request information of the terminal to the center, and to send the information the center answers to the request to the terminal.

Stations can receive bus type information, bus image, other station images through the center, and send them to personal terminals. The personal terminal can receive bus information through the station; if the bus is also installed, Two kinds of transceivers are used for communication. When the bus enters the communication area, the personal terminal can also receive information directly from the bus. The station and the center have combined information of the station, the bus route, and the bus driving direction, so the user of the personal terminal can reduce the input operation, and only needs to enter the starting point and destination, and can communicate with the station to obtain the information.

According to the above-mentioned system of buses, stations, and centers with information exchange, the data bank of the center has various bus information arranged according to bus numbers. This information includes: static information, such as whether air-conditioning is installed, whether there are stairs, whether wheelchair passengers can be carried. A bus that can carry wheelchair passengers has a function to determine whether such passengers are on board. When wheelchair-bound passengers get on and off, the driver sends this status information to the center via the transceiver. Passengers who need to use the bus service operated according to the passenger's riding needs, obtain the information collected by the center through the Internet, and send the boarding point, boarding time, alighting point, bus information, and transfer bus information to the center. After the center receives the passenger's riding demand, 'calculate a new driving route according to the demand, take this riding demand information into account, and recalculate the estimated time to arrive at each station along the line. These results are sent to the passengers who requested them. In addition, the center sends new routes, parking locations, and passenger needs to the bus, and the bus issues this information to the driver via a display or speaker. After confirming the information, the driver sends a confirmation signal for receiving the instruction. Each station modifies the estimated arrival time and displays demand information on the bus that receives passenger demand.

According to the above-mentioned system for information exchange of buses, stations, and centers, the center is connected to management servers of other transportation centers, such as railways and subways, and receives routes, timetables, and service information in a timely manner. The center estimates the time that each bus will arrive at the transfer station, and based on the timetable close to the estimated arrival time and the service of other modes of transportation, it extracts information on the other modes of transportation at the transfer station. The extracted information is sent to the station and the information of the relevant bus is displayed on the electronic station sign, or it is sent to the passenger's personal terminal through the second wireless communication function. Moreover, this information can be sent to the bus from the center or through the station, so that the passengers on the car also know the information. If real-time road traffic information can be used, the center can be connected to a management center that provides road traffic information to obtain the travel time of road traffic, which is used to estimate the time of bus arrival.

The advantages of the present invention are: it can collect and publish more and more accurate information on buses and stations, not only can help the center manage the fleet more efficiently, reduce operating costs, but also provide passengers with more useful information, such as Vehicle congestion, bus types, and fare information make it easier for passengers to choose the bus service that suits them.

Figure 1 shows the exchange of information between buses, stations and centers. The buses include: buses, trams, trolleybuses, light rail trains and subway trains. Each bus and each station is assigned a number, which can be an IP address. The transmission medium uses a wireless communication network, such as a cellular network, a wireless local area network, or a dedicated short-range communication (DSRC). Bus information, including the degree of congestion, bus type, charge information, whether or not wheelchair-bound passengers are in the car, etc., are collected by on-board detectors, such as cameras, and the cameras described in the present invention can use general cameras, such as analog The camera, or a digital camera, is processed by the information processor and sent to the center through the transceiver. The process is (101). After the data is processed in the center, it is sent to the electronic station sign at the station. The process is (10 ^). The present invention includes: a bus company operation management center, a traffic information service center, a traffic dispatch center, a traffic command center, and an information exchange center.

On the other hand, station information, such as the degree of congestion, is collected by a detector installed at the station, such as a camera, and then processed by the information processor and sent to the center through the transceiver. The process is as follows (103); after the center processes the data, Send to the vehicle display, the process is as (104>. Figure 2 shows a schematic diagram of a bus. Mounted on it are: a detector, such as a camera (201), an information processor (202), a display (203), and a transceiver (204).

Detectors are used to detect bus information, including congestion and service conditions.

The possible ways to detect the congestion of buses are:

One method is: In order to overcome the problem of overlapping, cover the inside panorama of the bus, and install several cameras (201) in different places on the bus. For example, it can be installed at the four corners of the car or a wide-angle lens can be installed at the top of the car. They work with a set program, such as taking an image every minute, and the shooting interval can be adjusted according to the communication cost and the requirements of the operator. In addition to this method, the camera (201) can also work according to the shooting requirements. If the vehicle-mounted device receives a shooting request from the center, the information processor (202) turns on the camera for shooting. When the image in the car is captured, it is compressed by the information processor (202) and sent to the center through the transceiver (204).

Another method is: install a sensor on each seat and choose several locations on the aisle to install the sensor too. The sensor can be light-triggered, such as infrared, or pressure-triggered. When the passenger triggers the sensor, the signal is transmitted to the signal processor. (202). The congestion in the car is calculated and sent to the center via the transceiver (204).

In order to identify different types of buses, such as whether the buses are equipped with air conditioners, ticket prices, and whether they can use monthly passes, each bus is assigned a number, which can be an IP address in a packet-switched network, such as a GPRS network. In this way, each data sent to the center is given this number. Through it, the center can identify the bus that sent the data and send the data to the corresponding station.

The display (203) is used to display various information sent from the center to the driver and passengers.

The information processor (202) and the transceiver (204) are responsible for information processing and transmission. The information processor (202) includes analog-to-digital conversion (A / D), encoding and decoding, encryption and decryption, and image compression. Images can be compressed into JPAG format. For different communication media, such as a cellular network, a wireless local area network, or a short-range dedicated communication (DSRC), the transceiver (204) may be multi-mode or single-mode. In the multi-mode mode, the transceiver antenna can work in a variety of networks and has multiple air interfaces. In the single-mode mode, the network selection depends on the construction cost, communication cost, and coverage. In order to detect the driving position of the bus, a G? S antenna may be included in the transceiver (204).

FIG. 3 shows an embodiment of a display mounted on a bus. This device can be used for bus operation management. It can be installed on the instrument panel in front of the driver of the bus, or it can be installed in other places in the car for easy navigation by passengers. The information (301) sent from the center is displayed in text form on the screen. For example, in a cellular network, a short message service (SMS) can be used. The screen is a liquid crystal display LCD (302). When the message arrives, the speaker (303) Make a sound. In this way, the driver or passenger is reminded of new information. The information includes: the distance from the bus in front, such as 350 meters from the nearest bus to the front, 750 meters to the second, and 1200 meters to the third, the congestion of the bus in front, such as the nearest A bus is very crowded, the second and third buses ahead are not crowded, the congestion at the next station, and other useful information. With this information, the driver can adjust the distance to the vehicle in front, improve operational efficiency, and ensure that waiting passengers do not have to wait too long.

Other types of displays containing the above information may also be implemented. '' Other information, such as news, announcements, and advertisements, can also be displayed to passengers.

Figure 4 shows a schematic diagram of a station. The stations include: buses, trams, trolleybuses, light rail trains and subway trains.

The station is equipped with a transceiver (401), an information processor (402), an electronic station sign (403), and a camera (404). The transceiver (401) receives the information sent from the center, and after processing by the information processor (402), it is displayed on the electronic station sign (403). The information includes: the congestion status of several buses that are about to enter the station, the type of buses, the toll situation, and other information.

The camera (404) captures the image of the station, compresses it through the information processor (402), and sends it to the center through the transceiver (401). It works under a set program, such as taking an image every minute, or working according to the requirements of the center operator.

Figure 5 shows an example of an electronic station sign installed at a station. In addition to the information displayed on traditional stop plates, line number (501), station name (502), first and last departure time (503), stations along the line (504), it also has several different characteristics: Location and congestion (505), bus type, fare and other information (506).

The location information of the bus (505) is realized by the global positioning system (GPS), which is indicated by the position of the small lights on the station board along the line: When a bus leaves station A and heads to station B, the / lights of station B 卞Lights up. When arriving at station B, the small light goes out, the small light at the next station C lights up, and so on. The position of the lit lamp allows passengers to know where the bus is running.

Bus congestion information (505) is realized by a vehicle-mounted detector, which is indicated by the number of small lights on the station board along the station

The head indicates that: 3 lighted small lights indicate high congestion, 2 lighted small lights indicate light congestion, and 1 lighted small light indicates no congestion, that is, there is space.

It can also reflect the degree of congestion in the car by the number of passengers or the distance between passengers observed by the camera installed in the compartment, and feedback the image information to the center. After the center makes image processing or image statistics, the center The electronic stop sign sent to the station shows the congestion. Types of buses that are about to enter the station, such as whether there is air conditioning, whether there are passengers with disabilities, and the fare information (506) is displayed in Chinese and English above the stop. Can use light-emitting diode screen (LED). Other information, such as weather conditions, announcements can also be displayed on it.

The type of the bus can be realized by the number of the bus, and different numbers indicate different types of buses. For example, air-conditioned cars, buses, and trams can be represented by different numbers. Can be displayed on the electronic station sign.

Other electronic station boards containing the above information can also be implemented.

Figure 6 shows a schematic of the center. It includes: a management server (601), a display (602), and a transceiver (603).

The management server (601) stores the data returned from the bus and the station in a database, and converts the data into a certain format according to different issuing terminals, such as a station electronic station sign, a bus display, and a personal terminal. The stored data includes: time, bus number, route number, bus type, location, congestion status, disabled passengers with and without wheel chairs, etc. It can provide operators with evidence and records of fleet management. The data format issued varies according to the terminal: For the electronic station sign of the station, the data is sent in a special encoding method to control the small lights; for the display on the bus, the data is sent in the text short message (SMS) format; for the personal terminal, For example, in mobile phones, data is sent in multimedia short message (MMS) format. Users only need to enter the destination name and send it to the application service provider (ASP) to get the recommended bus information, including the type of bus, congestion status, and fare. And other information. The user can also see the crowded image processing in the car made by the center or the bus image after statistics. The congestion status is shown by different colored symbols, red for highly crowded, yellow for lightly crowded, green for non-crowded, or different numbers of matches, three symbols for highly crowded, two symbols for lightly crowded, and one symbol Representatives are not crowded. The above application can be implemented by installing client software on the user terminal, and the programming language can be Java.

The display (602) is connected to the transceiver (603), and is used to monitor the situation in the car through the received images. The operator views the latest images by entering different bus numbers on the computer. The image interval can be adjusted as needed. The above applications can be implemented by installing server-side software on a central server.

The transceiver (603) receives and sends information through the network. Used to receive signals and transmit signals from buses and stations to buses, stations or other users. .,,

Figure 7 shows a flowchart of the information processor on the bus to determine the congestion situation based on the collected images.

A method for judging the congestion situation of a bus in a system of buses, stations and centers with information exchange, the specific process is as follows:

1. When each bus is empty, images from different angles are taken by cameras installed at different positions. Stored in the processor to be used as a judgment criterion for congestion; points on several images are selected as judgment points, such as selecting one point on each seat back and several points on the aisle;

2. After the camera captures images from different angles, the information processor compares them with the reference image stored in the processor. If the judgment point is covered, the information processor judges that the space of the point is occupied by passengers "3. If less than 100% of the judgment points on the seat are covered, and the congestion status is rated as "not crowded", that is, at least one seat is empty; if 100% of the judgment points on the seat are covered, less than 100

% Of the judgment points on the aisle are covered, and the congestion is rated as "lightly crowded"; if 100% of the seats and the judgment points on the aisle are covered, the congestion is rated as "highly crowded".

Figure S shows a flowchart of the information processor at the station judging the congestion situation based on the images of the collection.

A method for judging the congestion on a station in a system of buses, stations, and centers with information exchange, the specific process is as follows:

1. At each station when no one is waiting, the camera takes an image and stores it in the processor as a criterion for determining the congestion situation. Points on several images are selected as judgment points, such as selecting several on the roadside. point;

2. After the camera captures the image, the information processor compares them with the reference image stored in the processor. If the judgment point is covered, the information processor judges that the space of the point is occupied by the waiting passenger;

3. If less than 50% of the judgment points are covered, the congestion status is rated as "not congested"; if less than 100% of the judgment points are covered, the congestion status is rated as "lightly crowded"; if 100 % Of judgment points are covered and the congestion status is rated as "highly congested".

At the center (1401), the management server (1402) predicts the arrival time based on the information obtained from the outside, that is, the estimated arrival time to the transfer station is calculated from the traffic time of the road traffic information center (1404). This process is performed regularly at each bus and transfer station merge. Then, from the railway timetable, the railway information close to the time of arriving at the transfer station is selected, and the relevant real-time service information is further extracted. At the same time, the selected railway information is sent to each display of the bus (1405) and the station (1406) passing through the interchange station. As shown in FIG. 9, this information can be sent to the personal terminal PDA (1407) through the wireless local area network of the station (1406). This information can be further widely published on the Internet.

The above-mentioned system of buses, stations and centers with information exchange can be applied to taxi services. Passengers can choose a taxi from the provided taxi information. The above-mentioned method of adjusting the bus operation mode and recalculating the route according to passenger demand can also be applied to taxis as a general function.

The charging system of the above-mentioned bus, station and center system with information exchange is as follows: The center calculates the cost and cost of carrying each passenger in real time on the bus or taxi service according to the number of passengers, distance of the route, and vehicle class. The center then displays the calculated cost to the passenger before the passenger reserves the seat and gets on the bus. The passenger can reserve a seat based on the displayed fee, and the ride agreement is reached at the time of booking payment. Passengers can pay before or after the ride, and the cost varies depending on the payment method. In this way, passengers can choose the bus or taxi that is most suitable for them not only according to the route and vehicle class, but also according to the cost.

The above-mentioned system of bus, station and center with information exchange can also be applied to the operation and management of bus companies. When there are more passengers boarding a bus and there are passengers waiting, their images are transmitted to the center. The center forwards the congestion information of the bus to the next bus, and its driver adjusts the distance from the bus in front to shorten the waiting time for passengers. In this way, the bus company can timely adjust the fleet operation according to the passenger's riding needs, improve efficiency and reduce costs.

If the camera is installed on a long-distance passenger car, it can enhance the safety of operation. ¾ The working mode of the camera that can start shooting at any time according to the requirements of the center can be used in emergency situations. When there is a problem with the bus, the center can adjust the image in the bus in time. At the same time, the working mode of the camera's periodic shooting can be used to monitor the driver's working condition and ensure driving safety. If a violation occurs on a bus, the images taken by the camera can be used as evidence to track and prosecute the offender. If a second wireless communication device such as a wireless local area network is installed at the bus station, the broadband application of the Internet will be greatly promoted. Waiting passengers can use it to download real-time traffic information, multimedia entertainment information and other interesting content.

From the above description, it can be seen that a system of buses, stations, and centers with information exchange according to the present invention can be used not only for the collection and distribution of bus and station-related information, but also to exchange more useful information. It can also be used in railway transportation systems and civil aviation transportation systems.
