Detailed Description
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention comprehensible, specific embodiments accompanied with figures are described in detail below.
The embodiment of the invention provides a Radio Frequency Identification (RFID) tag device. Referring to fig. 1, a schematic structural diagram of a first rfid tag according to an embodiment of the present invention is shown. Fig. 2 is a schematic view illustrating a reading principle of a reader and an rfid tag device according to an embodiment of the present invention. Fig. 3 shows a schematic structural diagram of a carrier in an embodiment of the present invention. The rfid tag identification device 40 will be described with reference to fig. 1 to 3.
The rfid device 40 may include a first rfid tag 41, a second rfid tag 42, and a carrier 43. The first rfid tag 41 may include a sensing element 12 for sensing an environmental variable. When the sensing element 12 detects the environment variable of the environment, the first rfid tag 41 may be read. Accordingly, when the sensing element 12 does not satisfy the preset condition with respect to the detection result of the environment variable of the environment, the first rfid tag 41 may not be read.
The first rfid tag 41 and the second rfid tag 42 may be disposed on a carrier 43. In the embodiment of the present invention, the carrier 43 may be a clip, a packaging bag or a container, and may also be other devices that can be used to carry the first rfid tag 41 and the second rfid tag 42.
Referring to fig. 3, the carrier 43 is a clip, and a first placing groove 81 and a second placing groove 82 may be provided at both sides of the clip. The first placing groove 81 may be used for placing the first rfid tag 41, and the second placing groove 82 may be used for placing the second rfid tag 42. The gripper 43 may be used to secondary package the item to be managed, locate the item to be managed by reading from the rfid tag device 40 by the reader 30, or otherwise manage the item to be managed.
It is understood that the first placement groove 81 and the second placement groove 82 may also be located on the same side of the clip, and may be set according to the actual application scenario, and is not limited herein.
As can be seen from the above, since the first rfid tag device in the rfid tag device has the sensing element for sensing an environmental variable of the environment where the first rfid tag device is located, when the detection result of the sensing element on the environmental variable of the environment where the first rfid tag device is located satisfies the preset condition, the first rfid tag device can be read, which is beneficial to improving the intelligence of the rfid tag, for example, in combination with the reading condition of the second rfid tag device, the identification degree of the environment where the rfid tag device is located by the rfid system can be improved.
In some embodiments, the environment variables may include: at least one of temperature, humidity, light, etc. Accordingly, the sensing element may include at least one of a temperature sensing element, a humidity sensing element, and a light sensing element. The temperature sensing element may be a temperature sensor or a thermistor, or may be another device capable of sensing temperature. The humidity sensing element can be a humidity sensor or other devices capable of detecting the humidity. The light sensing element can be a light sensing sensor and other devices capable of detecting the intensity of light.
In an embodiment of the present invention, referring to fig. 1, the first rfid tag 41 may include an antenna and an integrated circuit 11 connected to the antenna. The inductive element 12 may comprise an environmental factor inductive switch coupled between the antenna and the integrated circuit 11. By providing an environmental factor sensitive switch, the rfid tag may be turned off or on based on identification of an environmental variable without significantly complicating the construction of the rfid tag device 40. The environmental factor sensing switch may include a thermal switch coupled between the antenna and the integrated circuit 11, which is turned off or on based on temperature recognition.
For example, the preset condition is that the thermo-sensitive switch is closed when the temperature is lower than a first threshold value. The thermal switch is closed when the temperature at which the first radio frequency identification tag is located is below a first threshold. The integrated circuit 11 of the first rfid tag 41 is connected and the reader 30 can read the data on the chip in the first rfid tag 41. When the temperature of the first rfid tag 41 is higher than the first threshold, the thermal switch is turned off, the integrated circuit 11 of the first rfid tag 41 is in an off state, and the reader 30 cannot read data on the chip of the first rfid tag 41. As another example, the first rfid tag 41 may be read when the preset condition is that the thermal switch is closed when the temperature is higher than the first threshold value. The first threshold value can be set according to actual application scenarios or actual needs.
In practical applications, the type of sensing element 12 may be selected based on the environmental variable characteristics corresponding to the scenario in which the rfid tag device 40 is used.
In a specific implementation, each radio frequency identification tag has a unique corresponding identifier, and related information of the identifier corresponding to the radio frequency identification tag can be stored in a chip of the radio frequency identification tag.
In a specific implementation, the first rfid tag 41 or the second rfid tag 42 in the rfid tag device 40 may be an active rfid tag, a semi-active rfid tag, or a passive rfid tag.
Passive rfid tags, also known as passive rfid tags, have no internal power supply and drive an integrated circuit by receiving rf waves, usually electromagnetic waves, from a reader. When a sufficiently strong signal is received by the antenna of the passive radio frequency identification tag, data may be sent to the reader. Some passive radio frequency identification tags can be provided with a magnetic induction coil, and when the magnetic induction coil is in the electromagnetic wave coverage range of a reader, magnetic induction current can be generated, so that power is supplied to an integrated circuit, the integrated circuit is conducted, and data is sent to the reader by means of energy generated by automatic magnetic induction current.
A semi-active radio frequency identification tag may be referred to as a semi-active radio frequency identification tag. Active radio frequency identification tags may also be referred to as active radio frequency identification tags. The semi-active radio frequency identification tag and the active radio frequency identification tag are internally provided with an internal power supply which can provide required power for the integrated circuit. The antenna of the semi-active radio frequency identification tag and the antenna of the active radio frequency identification tag do not need to be in charge of electromagnetic waves emitted by the reader, return signals between the antenna and the reader can be fully used, when a certain condition is met, the radio frequency identification tag can send out stored data, and the semi-active radio frequency identification tag and the antenna of the active radio frequency identification tag can have longer reading distance and faster response speed.
In some embodiments, the first radio frequency identification tag 41 may include: an antenna (not shown), an integrated circuit 11, a first control device (not shown) and a switch circuit (not shown). The switching circuit is connected in series with the antenna and the integrated circuit 11. When the sensing element 12 detects that the environment variable of the environment satisfies the preset condition, the first control device may control the switch circuit to be turned off or on, and when the switch circuit is turned on, the first rfid tag 41 may be read. Therefore, when the sensing element 12 is a temperature sensor, a humidity sensor, an illumination sensor, or the like, which can only sense an environmental variable but cannot directly control the on/off of the integrated circuit in the first rfid tag 41, the sensing element 12 can transmit a sensing result of the environmental variable to the first control device, and the first control device can control the on/off of the switch circuit according to the sensing result of the sensing element 12, so as to control whether the first rfid tag 41 can be read, thereby improving the range of the sensing elements that can be used.
In some embodiments, the second rfid tag 42 may have a sensing element for sensing the environmental variable, and may further include an antenna and an integrated circuit, and the sensing element may be coupled between the antenna and the integrated circuit. The inductive element of the second rfid tag 42 is capable of sensing a different environmental variable than the inductive element of the first rfid tag.
In other embodiments, the second radio frequency identification tag 42 may be read independent of the environmental variable. For example, the integrated circuit of the second rfid tag 42 is a normally-on circuit, and the integrated circuit is always in a connected state and is not affected by the environment variable.
It is understood that the number of rfid tags included in the rfid tag device 40 may be more than two, for example, a third rfid tag, a fourth rfid tag, or the like may be included while the first rfid tag 41 and the second rfid tag 42 are included. The number of rfid tags in the rfid tag device 40 may be set according to actual needs, and the number of rfid tags set in the rfid tag device 40 is not limited herein.
Referring to fig. 4, an embodiment of the present invention also provides an rfid system, which may include a reader 30 and an rfid tag device 40.
In a specific implementation, the rfid tag device 40 may adopt the rfid tag device 40 provided in any of the above embodiments of the present invention, and the specific structure, operation principle and process of the rfid tag device 40 may refer to the description of the rfid tag device 40 in any of the above embodiments of the present invention, which is not described herein again.
The reader 30 may include a radio frequency module, an antenna, a power supply, a control processing module, and the like. The rf module may transmit rf waves, which are generally electromagnetic waves, to the outside through the antenna. The antenna in the reader 30 may also receive a feedback signal and data sent by the rfid tag, and the control processing module may analyze and process the received data.
The reader 30 may be coupled to the rfid tag device 40, and may read the first rfid tag 40 when the detection result of the environment variable where the sensing element 12 is located satisfies a preset condition. When the reading of the second rfid tag 42 is independent of the environmental variable, the second rfid tag 42 can be read when it is in the radio-frequency wave radiation range of the reader. When the reading of the second rfid tag 42 is correlated to an environmental variable, then the reading may or may not be read depending on the environmental variable of the environment in which the second rfid tag 42 is located.
The radio frequency identification system may comprise a second control device 20. The second control device 20 is coupled to the reader 30, and can determine the location information of the rfid tag device 40 according to the read feedback of the first rfid tag 41 and the second rfid tag 42 in the rfid tag device 40 read by the reader 30, wherein the location information of the rfid tag device 40 is associated with at least one environmental variable of the environment in which the rfid tag device 40 is located. Environmental variables may include temperature, humidity, light, etc.
The second control device 20 and the reader 30 may be provided relatively independently, i.e., two relatively independent devices. The second control device 20 may be integrated with the reader 30, and the existence of the second control device 20 is not limited herein as long as the function of the second control device 20 can be realized.
Referring to fig. 5, the embodiment of the present invention further provides a storage device 90, and the storage device 90 may include a first storage space 91, a second storage space 92, and any one of the rfid systems provided by the embodiments of the present invention. The first and second storage spaces 91 and 92 have different environmental variables. The rfid tag device 40 is removably placed with the first storage space 91 or the second storage space 92, and the first rfid tag 41 is readable in the first storage compartment 91 and is not readable in the second storage compartment 92. It will be appreciated that the first rfid tag 41 may also be configured to be read in the second storage compartment 92 and not be read in the first storage compartment 91.
In a specific implementation, reference may be made to the description of the rfid tag device 40 in any of the above embodiments of the present invention for the structure and the working principle or process of the rfid tag device 40, and no further description is provided herein.
The reader 30 is coupled to the rfid tag device 40, and can read the second rfid tag 42 and the first rfid tag 41 when the environmental variable of the environment in which the sensing element 12 is located in the first rfid tag 41 satisfies a predetermined condition.
The second control device 20 may be coupled to the reader 30, and may determine the location information of the rfid tag device 40 according to the reading feedback of the first rfid tag 41 and the second rfid tag 42 of the reader 30.
The location information may be that the rfid tag device 40 is located in the first storage space 91 or that the rfid tag device 40 is located in the second storage compartment 92.
In an implementation, the first rfid tag 41 and the second rfid tag 42 in the rfid tag device 40 may be associated, and the corresponding location information of the first rfid tag 41 and the second rfid tag 42 may be preset, and when only one of the first rfid tag 41 and the second rfid tag 42 is read, which storage space the rfid tag device 40 is located in may be determined according to the preset corresponding location information. When the first rfid tag 41 and the second rfid tag 42 are read at the same time, it is determined which storage space the rfid tag device 40 is located in according to the preset defined location information.
In an embodiment of the present invention, the second control device 20 is configured to determine that the rfid tag device 40 is located in the first storage space 91 when the first rfid tag 41 and the second rfid tag 42 are read.
In another embodiment of the present invention, the second control device 20 is configured to determine that the rfid tag device 40 is in the second storage space 92 when only the second rfid tag 42 of the rfid tag device 40 is read.
It will be appreciated that the second control device 20 may also be configured to determine that the rfid tag device 40 is in the second storage space 92 when the first rfid tag 41 and the second rfid tag 42 are read. When the second rfid tag 42 in the rfid tag device 40 is read only, it is determined that the rfid tag device 40 is located in the first storage space 91. In practical applications, the position information of the rfid tag device 40 in the storage apparatus 90 can be determined according to the sensing condition of the sensing element 12 in the first rfid tag 41 to the environmental variable and the reading condition of the second rfid tag 42.
In some embodiments, the second RFID tag 42 may be read independent of environmental variables, which may reduce the cost of the second RFID tag 42.
In other embodiments, the second rfid tag 42 may also include a sensing element for sensing an environmental variable, and the second rfid tag 42 may be read when the sensing element detects the environmental variable and the sensing element satisfies a predetermined condition. The preset condition corresponding to the sensing element of the first rfid tag 41 is different from the preset condition corresponding to the sensing element of the second rfid tag 42.

In practical application, specific values of parameters of the environment variables can be set according to practical application scenarios, and the specific values listed in the embodiment of the present invention are only for illustration and do not limit the values of the environment variables.
Taking the storage device 90 as an example of a refrigerator, the first rfid tag 41 may be associated with a freezer compartment and the second rfid tag 42 may be associated with a refrigerator compartment. When the reader 30 reads the first rfid tag 41 and the second rfid tag 42 at the same time, it is determined that the rfid tag device 40 is located in the freezer compartment, and when only the second rfid tag 42 is read, it is determined that the rfid tag device 40 is located in the refrigerator compartment. This allows the reading of the second rfid tag 42 to be set independently of the environment variable, which reduces the cost of the second rfid tag 42.
One storage apparatus 90 may be pre-associated with a plurality of rfid tag devices 40, each rfid tag device 40 being unique. When the rfid tag device 40 is not placed on an article, the rfid tag device 40 may be placed in a predetermined area of the storage device 90, and the predetermined area may be provided with a signal shielding device for shielding signals of the first rfid tag 41 and the second rfid tag 42 of the rfid tag device 40, and when the rfid tag device 40 is located in the predetermined area, the reader 30 cannot read the first rfid tag 41 and the second rfid tag 42 of the rfid tag device 40. When the rfid tag device 40 is taken out from the setting area, the reader 30 can read the first rfid tag 41 and the second rfid tag 42 under certain conditions.
In practice, the storage facility 90 may include more than 2 storage compartments, and there are accordingly a number of situations where items may be placed. In order to accurately know the placement position of the article, the number of the rfid tags included in the rfid tag device 40 may be the same as the number of the storage compartments, and the rfid tags included in the rfid tag device 40 correspond to the storage compartments, respectively, and can be read after being placed in the corresponding storage compartments, so that the placement position of the article can be determined according to the rfid tags read in the rfid tag device 40.
For example, the storage device 90 is a refrigerator having three storage compartments with different temperature zones, namely a freezing compartment, a refrigerating compartment and a fresh food compartment, wherein the temperature of the freezing compartment is set to be lower than-16 ℃, the temperature of the refrigerating compartment is set to be 2-6 ℃, and the temperature of the fresh food compartment is set to be-3-0 ℃. Thus, 3 rfid tags in the rfid tag set may correspond to three storage compartments, respectively, the first rfid tag being read at a temperature below-10 c, the second rfid tag being read at a temperature below 1 c, and the third rfid tag being read independently of temperature. When the third radio frequency identification label is read, determining that the goods are in the refrigerating chamber; when the second radio frequency identification tag and the third radio frequency identification tag are read, determining that the article is in the fresh-keeping room; when the first radio frequency identification tag, the second radio frequency identification tag and the third radio frequency identification tag are read, it is determined that the article is in the freezing chamber.
In one embodiment, the storage device 90 may include a refrigerator, an ice chest, a shelf, etc., and may be other storage devices having different environmental variables, which are not illustrated herein.
By adopting the mode of the radio frequency identification tag device, the radio frequency identification tags of various types can be not needed to be distinguished, and a user does not need to know the difference of the environmental variables which can be sensed by the sensing element of the radio frequency identification tag, before the articles are placed in the storage equipment, the radio frequency identification tag device can be placed on the articles, after the articles with the radio frequency identification tag group are placed in the storage equipment, the reader can read the first radio frequency identification tag and/or the second radio frequency identification tag in the radio frequency identification tag device, so that the articles can be correspondingly managed according to the read radio frequency identification tags, and the convenience, the perfection and the intellectualization of article management can be further improved.
In order to facilitate better understanding and implementation of the embodiments of the present invention for those skilled in the art, the embodiments of the present invention further provide an article management method, and the detailed description of the specific steps of the article management method is provided below with reference to fig. 6.
Step S1, reading the second rfid tag.
In particular implementations, the second radio frequency identification tag may be read independently of the environment variable or may be selectively read based on the environment variable. When the reading condition of the second radio frequency identification tag is related to the environment variable, the second radio frequency identification tag may include an induction element for inducing the environment variable, and when a detection result of the induction element on the environment variable of the environment meets a preset condition, the second radio frequency identification tag may be read.
Step S2, it is determined whether the first rfid tag associated with the second rfid tag is read.
In a specific implementation, the second rfid tag may be pre-associated with a first rfid tag, and the first rfid tag is provided with an induction element for inducing an environmental variable, and when a detection result of the induction element on the environmental variable meets a preset condition, the first rfid tag is read. When the detection result of the sensing element on the environment variable does not meet the preset condition, the first radio frequency identification tag cannot be read.
In a specific implementation, reference may be made to the description of the first rfid tag or the rfid tag apparatus in any of the above embodiments of the present invention for the structure and the working principle of the first rfid tag, which is not described herein again.
Step S3, determining the location information of the first rfid tag and the second rfid tag according to the read feedback of the first rfid tag and the second rfid tag.
For example, when the second rfid tag is read but the first rfid tag is not read, it may be determined that the article corresponding to the first rfid tag and the second rfid tag is at location a. For another example, when the second rfid tag is read and the first rfid tag is read, it may be determined that the article corresponding to the first rfid tag and the second rfid tag is located at the location B. For another example, when the first rfid tag is read but the second rfid tag is not read, it may be determined that the article corresponding to the first rfid tag and the second rfid tag is at the location B. It can be understood that the reading conditions of the first rfid tag and the second rfid tag and the placement positions of the corresponding articles may be set according to actual application scenarios or reading conditions of the first rfid tag and the second rfid tag.
According to the scheme, the placing position of the article is determined according to the reading condition of the first radio frequency identification tag and the second radio frequency identification tag corresponding to the article, and when the placing position of the article is determined, the position is determined without manpower, so that convenience, perfectness and intellectualization of article management can be improved.
In a specific implementation, after the placement position of the article is determined, corresponding management operation can be executed according to the information position of the article. For example, a storage period of an item associated with the first and second radio frequency identification tags is set according to the location information. As another example, an optimal placement of the item is recommended. The probability that the corresponding article of the radio frequency identification tag device is placed in the environment which does not correspond to the article is reduced.
In a specific implementation, a start time for determining a location of an item may be obtained, a set storage duration instruction may be received, and a storage deadline of the item may be determined based on the start time and the received storage duration instruction.
For example, after beef is determined to be placed in the refrigerating chamber of the refrigerator, the beef position determination starting time can be determined to be 2018, 10, month, 22, day 9:00, the received storage duration instruction can be that the storage duration input by the user on the human-computer interaction interface of the refrigerator is three days, and therefore the storage duration of the beef is 2018, 10, month, 25, day 9: 00. The received set storage duration instruction may also be a preset storage duration, the preset storage duration may be unique and default, or may include a plurality of storage duration options, and the storage duration option is selected by the user from the plurality of options.
For another example, after determining to place the ice cream in the cold room of the refrigerator, it may be recommended that the optimal placement position of the ice cream be the freezer room to prompt the user to adjust the placement position of the ice cream, which may enable the optimal preservation of the item.
In practical applications, there may be a plurality of taking-in and taking-out situations according to different types of the articles to be managed, and after each taking-out and returning-back, the first rfid tag or the second rfid tag of the article may be read again. In order to avoid confusion caused by the above situation on article management and improve the orderliness on article management under the above situation, in the embodiment of the present invention, when a first radio frequency identification tag or a second radio frequency identification tag corresponding to an article is obtained for multiple times within a preset first time period, a time at which the first radio frequency identification tag or the second radio frequency identification tag is obtained for the first time within the preset first time period is used as a start time for determining a position of the article.
In a specific implementation, the first time period may be set according to actual needs. For example, 10 apples in a bag are placed in a refrigerator. It is expected that 5 days will be consumed, then the first time period may be set to 5 days. Within 5 days, when the apple bag is taken out of the refrigerator, some apples are taken out of the bag, and then the rest apples are put back into the refrigerator, although the first radio frequency identification tag or the second radio frequency identification tag on the apple bag is read every time the apples are put back, the storage period of the apple bag is calculated by taking the time when the first radio frequency identification tag or the second radio frequency identification tag is read for the first time as the starting time.
In order to further enhance the intelligence of article management, the embodiment of the invention can also send out the overdue reminding information when the storage period of the article at the current moment is detected to be within a preset second time. The article which is about to expire can be timely reminded to be used for processing the article by sending out expiration reminding information, and the problem that the article is deteriorated due to the fact that a user forgets the article into the storage equipment is avoided.
In specific implementation, the expiration reminding information can be displayed on a display interface of storage equipment such as a refrigerator and the like, and can also be pushed to a user terminal associated with the storage equipment. It will be appreciated that the display may also be made in other ways.
In the implementation, the specific working principle and the flow of the article management method may also refer to the descriptions in the rfid tag device, the rfid system, and the storage device provided in the above embodiments of the present invention.
Those skilled in the art will appreciate that all or part of the steps in the methods of the above embodiments may be implemented by associated hardware instructed by a program, which may be stored in a computer-readable storage medium, and the storage medium may include: ROM, RAM, magnetic or optical disks, and the like.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
