Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
In the description of the present invention, the meaning of a plurality of means is one or more, the meaning of a plurality of means is two or more, and more than, less than, more than, etc. are understood as excluding the present number, and more than, less than, etc. are understood as including the present number. If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
Referring to fig. 1, the method of an embodiment of the present invention includes the steps of: sending a reading request to an electronic tag according to a preset communication frequency band, wherein a plurality of chips with different air interface protocols are implanted in the electronic tag; determining an air interface protocol chip to be read according to the communication frequency band, and acquiring vehicle identity identification information stored in the air interface protocol chip; and analyzing the vehicle identity identification information according to the air interface protocol type of the air interface protocol chip to obtain an analysis result, and returning corresponding analysis content according to the reading request.
In the embodiment of the invention, a plurality of chips with different air interface protocols are arranged in the electronic tag, different communication frequency bands can be configured according to the air interface protocols, and all the communication frequency bands are not overlapped. For example, a chip of a first air interface protocol is accessed through a first communication frequency band (e.g., 920 to 925Mhz), and a chip of a second air interface protocol is accessed through a second communication frequency band (e.g., 840 to 845 Mhz).
In the embodiment of the present invention, referring to fig. 2, according to an application scenario of vehicle management, a communication frequency band may be preset, and at this time, an APP (application program) in a certain application scenario or an air interface protocol chip in an electronic tag is fixedly read. In fig. 2, two air interface protocol chips, chip a and chip B, are provided in the electronic tag. The air interface protocols of the chip a and the chip B are different, a vehicle identification file, referred to as a first identification file in the invention, is stored in the memory of the chip a, and a vehicle identification file, referred to as a second identification file in the invention, is also stored in the memory of the chip B. The vehicle identification data stored in the first identification file and the second identification file may not be completely the same, and the vehicle identification data includes, but is not limited to, vehicle information, license plate type, license plate number, service information, service permission status, and the like; service information such as owner information, service approval status such as clearance approval, and the like. When the vehicle management device (or the application program APP) sends out a reading request in a first communication frequency band, the electronic tag returns the vehicle identification information (namely a first identification file) in the chip A; when a reading request is sent out in the second communication frequency band, the electronic tag returns the vehicle identification information (namely, the second identification file) in the chip B. The vehicle management equipment (or APP, namely an application program) sends a radio frequency signal with a certain frequency through the transmitting antenna, and when the electronic tag enters a working area of the transmitting antenna, induced current is generated, so that the obtained energy is activated; and the electronic tag sends the identification information in the air interface protocol chip out through the built-in sending antenna of the card. Through a polling mode, whether the electronic tag returns the vehicle identity identification data in the chip to be read can be judged. For example, when the chip to be read is the chip a, polling is performed to find whether a returned first identification file exists, if so, it indicates that data acquisition is completed, and a next data analysis step is performed, that is, vehicle identification data is analyzed according to the type of the air interface protocol of the chip to be read, and corresponding analysis data is returned to the vehicle management device (or the application program APP) according to the content of the reading request. It should be understood that the method of the embodiment of the present invention is compatible with an electronic tag that handles a single air interface protocol, for example: the electronic tag only containing an air interface protocol chip A can be processed in the application scene of the read-only coring chip A; and if the chip A is not included in the electronic tag, performing alarm processing, and performing operations such as photographing on the corresponding vehicle.
Referring to fig. 3, the electronic tag reading apparatus 100 of the present invention includes: a data request module 110, a data collection module 120, a data analysis module 130 and a communication frequency band setting module 140. The data request module 100 is configured to send a reading request to the electronic tag according to a preset communication frequency band. The data acquisition module 120 is configured to determine a chip to be read from an air interface protocol chip implanted in the electronic tag according to the communication frequency band, and acquire vehicle identification data in the chip to be read; and the data analysis module 130 is configured to analyze the vehicle identity data according to the type of the air interface protocol of the conference chip to be read, and return a corresponding analysis result according to the reading request. And a communication frequency band setting module 140, configured to set a communication frequency band in advance according to an application scenario of vehicle management.
