Application and implementation of RFID tags in automobile supervision

RFID technology has been widely used in the automotive industry, mainly reflected in the popularization of remote supervision systems for automobile qualification certificates. The system includes OBD interface monitors, vehicle certificate supervision boxes, ultra-high frequency reading and writing equipment, application system software, and big data collection and processing.

In terms of automobile logistics supervision, the system uses the OBD interface to monitor vehicles and report location information in real time to achieve real-time tracking during transportation. At the same time, RFID technology is used for inventory query. By attaching RFID electronic tags to the vouchers, real-time monitoring of automobile vouchers is achieved. All monitoring data is transmitted to the background through wireless networks. The server analyzes and mines the data to timely warn and control risk behaviors.

The system can provide a series of services such as vehicle supervision, physical verification, vehicle inventory, risk alarm, vehicle after-sales maintenance, and data intelligent analysis. It analyzes inventory data through various mathematical models and generates risk assessment reports. Risks of different types and levels will enter the corresponding risk management process, thereby completely solving the problems existing in the current vehicle certificate supervision model, significantly improving work efficiency, and reducing the operating costs of all parties.

Solution

1. Embedded RFID Reader to realize document RFID electronic tag identification

This solution embeds the RFID reader into the supervision box to realize automatic identification of the document RFID electronic tag. The supervision box has a built-in main control single-board computer, which realizes the integrated processing of data collection, storage and transmission through the connection with the cabinet door sensing digital signal, wireless communication equipment and RFID equipment.

2. Remote monitoring File technology

By embedding the wireless communication module in the supervision box and sending the data to the data center in real time through software control, remote monitoring of files can be realized.

3. Optimize the RFID tag anti-collision algorithm to improve the card reading speed

In view of the problem of RFID tag conflict in the RFID system, the RFID tag anti-collision algorithm is optimized to improve the card reading speed. By studying the commonly used tag conflict resolution method and the binary tree anti-collision algorithm, the algorithm is optimized to improve the card reading efficiency.

4. Quickly find files through the supervision box control panel

By designing the supervision box control panel, the working status of the supervision box is displayed, and the file number input function is provided to facilitate users to quickly find the grid where the files are Stored.

5. Built-in supervision box status sensing system

The built-in supervision box status sensing system monitors the status of the cabinet door, power supply, etc. The cabinet door switch controls the single-board computer through digital I/O signal input to realize real-time monitoring of the cabinet door. After the cabinet is powered off, the backup battery will automatically start and send power outage information to the monitoring center.

6. Establish a unified supervision business platform based on RFID technology

Based on RFID technology, establish a new set of supervision business platform to replace the traditional manual supervision business, and realize comprehensive supervision of enterprise management through new exploration and research on supervision business and information system construction.

7. Massive data processing technology

Introduce mature website load balancing technology, perform massive data parallel transmission processing on high-concurrency TCP/IP clients (file cabinets), use data read-write separation technology and partitioning technology to optimize data storage and processing, and improve the system's storage and processing capabilities.

Establish independent data analysis service software, conduct risk analysis on massive data regularly according to the preset analysis model, and generate complete risk analysis reports, which are output in multiple file formats.

8. Use data compression algorithm to increase storage capacity and reduce data transmission pressure

The current RFID UHF standard compresses 18 bytes of data into 12 bytes through data compression algorithm and stores it in the EPC area. During the transmission process, only the compressed data is transmitted, which reduces the pressure of data transmission and increases the storage capacity of the EPC area.

9. Intelligent analysis algorithm, converted into business data

Through the intelligent analysis algorithm, the single label data uploaded by the supervision box is converted into business data that can be manually identified, for example, the legality of entering and leaving the cabinet is analyzed, and the overtime time of leaving the cabinet is analyzed through historical records, etc., to realize the utilization of basic data.
