[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model. It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict.
[0025] Specific implementation method 1: refer to Figure 1 and Figure 2 Specifically describing this embodiment, a recording device of a railway car number intelligent recognition device described in this embodiment includes: a car number host recording plug-in board that can be inserted into the spare slot of the railway car number intelligent recognition device, the car number host recording plug-in board can transmit data with the car number host radio frequency plug-in board and the car number host control plug-in board of the railway car number intelligent recognition device, and record the working state, input state and output state of the railway car number intelligent recognition device. The car number host recording plug-in board can also send its recorded data to the ground information management platform via 5G.
[0026] This embodiment adopts a plug-in structure that can conveniently and quickly record the operating data of the AEI host, increase the maintainability of the equipment, and save manpower, material resources and equipment replacement costs. By sending the recorded data remotely via 5G, data analysis and display can be realized on the host computer. In specific applications, the vehicle number host recording plug-in is inserted into the spare slot of the AEI host, and it can be connected to the RF board and control board of the AEI host through the serial port. The I / Q decoding data of the AEI device, the local oscillator output (frequency) of the RF board, the output power of the RF board, the antenna standing wave ratio, the working status of the AEI host, and the data sent by the AEI to the 5T device can be obtained.
[0027] This implementation can record all records during the operation of the AEI host, including but not limited to the output RF power of the AEI host, the host working status (decoding information, serial port sending information, network configuration information, etc.), RF tag information, etc.
[0028] Specific implementation method 2: refer to Figure 3Specifically describe this embodiment, this embodiment is a further description of the recording device of a railway vehicle number intelligent recognition device described in the specific embodiment one. In this embodiment, the vehicle number host recording plug-in board includes: a core processing module, a serial port module, a clock module, a card slot, a display module, a USB module, a system power supply module and a 5G wireless module.
[0029] The core processing module uses the GD32F470ZIT6 chip to perform the core processing of the entire device, mainly completing the control of the entire plug-in board and allocating the functions and processing of each module. Its connection relationship is as follows:
[0030] The status signal input and output ends of the core processing module are connected to the status signal input and output ends of the card slot, the status signal input end of the core processing module is connected to the signal output ends of the vehicle number host RF plug-in board and the vehicle number host control plug-in board through the serial port module, and the clock signal input end of the core processing module is connected to the clock signal output end of the clock module.
[0031] The clock module is controlled by the core processing module, and then the SD2506API chip is used as the built-in real-time clock. The clock module outputs the time and can be timed by satellite (including but not limited to Beidou, GPS, GLONASS, Galileo, etc.) to ensure the stability of the system time.
[0032] The card slot is used to connect a storage device for local data storage, including but not limited to SD card, TF card and CF card. By storing data files in multiple ways, data loss due to failure of a certain way is avoided, and the security and re-readability of data storage are guaranteed.
[0033] The display module is a digital tube, and the status signal input end of the display module is connected to the status signal output end of the core processing module. The digital tube displays the error code, dump status and working status.
[0034] The USB module is used to connect the core processing module to an external USB disk. The USB module is mainly used to dump the data of the recording board by inserting a USB disk, and can record the board program upgrade and device configuration through the USB module.
[0035] The system power supply module is used to supply power to the core processing module. The system power supply module uses the VRB0505ZP-6WR3 module to convert 6V isolation to 5V, and then uses the H7651-33PR to convert 5V to 3.3V for powering each module.
[0036] The core processing module exchanges data with the ground information management platform through the 5G wireless module.
[0037] The serial port module connects the recording board plug-in board (including but not limited to CAN, RS485, RS422, etc.) with the radio frequency board and the control board to achieve communication and data transmission between the boards.
[0038] The 5G wireless module uploads the recording results to the ground information management platform through 5G wireless transmission to facilitate data storage and review.
[0039] In addition, the existing AEI host can only send successfully identified information to the host computer or 5T device, and will not send unidentified information, which will result in the loss of some tag information. This embodiment can record all information and avoid the problem of missing information.
[0040] like Figure 4 As shown, the working process of the recording device of a railway vehicle number intelligent recognition device described in this embodiment 1 is as follows:
[0041] 1. The device is powered on, all modules are initialized, and the system power supply module provides voltage output for other modules;
[0042] 2. The recording board detects and records the working status, input status, output status, etc. of the AEI host through the core processing module + serial port module;
[0043] 3. When the AEI host receives an external signal, the RF board sends the "raw signal data" to the recording board through the serial port module. The recording board synchronizes the time output by the clock module and starts the timing function to continuously receive the data received by the RF board;
[0044] 4. The power amplifier related information of the control board is sent to the recording board through the core processing module + serial port module. The recording board records the power amplifier status (including but not limited to output frequency, power, standing wave ratio and other related equipment information) and writes it into the storage module and the memory card of the plug-in panel;
[0045] 5. Whenever the label information from the external input is received, the storage module writes the data once, including all I / Q demodulated and undecoded data;
[0046] 6. The core processing module is responsible for realizing the synchronous transmission of I and Q data from the RF board to the recording board;
[0047] 7. The core processing module receives the serial port module signal and transmits it to the ground information management platform through the 5G wireless module for data analysis and display;
[0048] 8. If you need to save the data separately, you can connect the memory card or USB module through the card reader to perform data dump operation.
[0049] 9. If system configuration and upgrade are required, you can use an external USB flash drive to connect the USB module for operation.
[0050] After recording and processing, this implementation method sends the AEI host working status, input and output data and other information to the ground information management platform through the 5G module for data analysis and display. It can also be output and dumped through the front panel USB interface for review.
[0051] Although the present invention is described herein with reference to specific embodiments, it should be understood that these embodiments are merely examples of the principles and applications of the present invention. It should therefore be understood that many modifications may be made to the exemplary embodiments, and other arrangements may be designed without departing from the spirit and scope of the present invention as defined by the appended claims.
