Problems solved by technology

In practical applications, usually the antenna of each lane only trades with the vehicles in this lane. When a vehicle crosses the lane, the vehicle belongs to two lanes. For this vehicle transaction, the identification may fail due to signal superposition, or the antenna resources are wasted because the antennas of the two lanes have marked the vehicle’s label.

Embodiment 1

[0041] Please refer to figure 2, the present application provides a path identification system, the system includes: at least two antennas and a controller.

[0042] Each of the at least two antennas (ie, antenna 1 to antenna N, where N is a positive integer greater than 1) corresponds to at least one lane. In at least one transaction step (in some preferred embodiments, in each transaction step), only one antenna is used as an effective antenna to send broadcast data to its corresponding lane range, and each antenna receives the information returned by the vehicle tag based on the broadcast data. A response frame, the response frame at least includes the MAC address of the vehicle tag; when the antenna receives the response frame, it does not process the response frame data, and directly transmits the received response frame to the controller.

[0043] The controller is used to select one antenna from at least two antennas as an effective antenna according to the received r...

Embodiment 2

[0081] Please refer to Figure 5 , Correspondingly, based on the above path identification system, the present application provides a path identification method of the path identification system, the method includes: in at least one transaction step (in some preferred embodiments, in each transaction step) ,

[0082] Step 100, only one antenna is used as an effective antenna to send corresponding data to the current vehicle tag, and each antenna receives a response frame returned by the vehicle tag based on the corresponding data, and the response frame includes at least the MAC address of the vehicle tag;

[0083] Step 200, each antenna transmits the received response frame to the controller;

[0084] Step 300, the controller selects an antenna from antenna 1 to antenna N as the effective antenna for the next transaction step according to the received response frame and preset rules, and controls the effective antenna to send data corresponding to the next transaction step t...

Embodiment 3

[0093] The present application provides another path identification system, which includes: a memory and a processor. Wherein, the memory is used to store programs; the processor is used to execute the programs stored in the memory to implement the method described in the second embodiment.

[0094] Those skilled in the art can understand that all or part of the functions of the various methods in the foregoing implementation manners can be realized by means of hardware, or by means of computer programs. When all or part of the functions in the above embodiments are implemented by means of a computer program, the program can be stored in a computer-readable storage medium, and the storage medium can include: read-only memory, random access memory, magnetic disk, optical disk, hard disk, etc., through The computer executes the program to realize the above-mentioned functions. For example, the program is stored in the memory of the device, and when the processor executes the pr...

Abstract

The invention provides a path recognition system and a path recognition method thereof and a readable storage medium. The system comprises at least two antennas and a controller. According to the pathrecognition system, the controller only selects one antenna from at least two antennas to transmit data to the current vehicle-mounted tag in at least one transaction step so that data receiving andtransmitting of multiple antennas can be coordinated, the current vehicle-mounted tag is enabled to perform stable path identification in case of path identification whether the vehicle changes the lane or crosses the lane or is in the corresponding lane range of multiple antennas, and thus the success rate of the path recognition system can be guaranteed and waste of the antenna resources can bereduced.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a path recognition system, a path recognition method, and a readable storage medium. Background technique [0002] The route recognition system is used to solve the problem of ambiguous route identification of vehicles. By writing the route identification information into the vehicle tag when the vehicle passes through the identification point, it can identify the vehicle's driving according to the entrance information and route identification information when exiting the expressway. Routes, to calculate and collect tolls for vehicles. The path identification system mainly includes the on-board label OBU and the roadside base station RSU, wherein the roadside base station RSU is installed at each identification point. [0003] Since there are fast lanes, overtaking lanes, emergency lanes and even more lanes in each direction of the expressway, in order to achi...
