1. Business requirements
At present, there are many problems in the supervision of vehicles and goods in important areas such as warehouses, ports, ports, airports, bonded areas, import and export truck inspection sites, import and export processing areas, mining area vehicle inspection stations, and oil depots. The traditional method uses manual registration, the amount of recorded information is limited, real-time monitoring is not possible, and the work efficiency is low. It is prone to inaccurate recorded information, lost goods, etc., and relevant information cannot be monitored and refreshed in real time. The establishment of a radio frequency identification vehicle and cargo intelligent supervision system can realize automatic identification, verification of vehicle information, automatic recording and collection of information, greatly reducing the workload of personnel, improving work efficiency, and greatly reducing errors caused by human operations, and at the same time strengthening It is of great significance to effectively supervise important and sensitive goods, increase the speed of vehicle entry and exit, and realize paperless supervision of goods.
Second, the system architecture
The RFID vehicle and cargo intelligent supervision system is composed of “VID-C2 Radio Frequency Identification Card”, “VID-B2 Radio Frequency Base Station System”, “VID-M2 Radio Frequency Base Station Monitoring System”, “VID-Q2 Handheld Auditor”, and “VID -Q3 vehicle inspection instrument” and system and application software composition, its principle is: each vehicle is installed with Dingzhi “VID-C2 radio frequency identification card” to establish a corresponding relationship between the goods carried by the vehicle and the vehicle (ie, “bundling of vehicles and goods”) , When the vehicle passes through the identification area of the “VID-B2 Radio Frequency Base Station System”, the radio frequency identification card information is collected through the radio frequency base station system, the information is analyzed and judged, and the relevant information records of the vehicles and goods in the area are obtained and transmitted to The back-end database and the corresponding vehicle guidance instructions are issued to the radio frequency identification card, so as to provide fast path guidance to the vehicle. System users can share, analyze, and process all data through application software, so as to intelligently supervise vehicles and goods, realize informatization and automation of management work, and achieve the purpose of reducing burdens and increasing efficiency. Supervision units can use Dingshi “VID-Q2 Handheld Auditor” and “VID-Q3 Vehicle-mounted Auditor” to conduct effective inspection and management of vehicles, goods, and drivers.
Three, application process
The application process of the RFID vehicle and cargo intelligent supervision system is shown in Figure 1B. After the vehicle enters the identification area of the radio frequency base station system, the radio frequency identification card installed on the vehicle is activated by the signal sent by the radio frequency base station system. The radio frequency base station system obtains the data of the radio frequency identification card and transmits it to the radio frequency base station monitoring system.Radio base station monitoring system completedRFIDThe business processing of card data realizes various functions such as vehicle deployment control, cargo inspection, vehicle payment, inspection guidance, and entry and exit area records, and implements comprehensive monitoring of vehicles and goods entering and exiting the area. The system and application software process relevant data according to predetermined functions.
Four, software example
Based on the Windows platform, part of the system software interface.
Five, system characteristics
1. Use radio frequency identification technology to establish an “electronic channel” for intelligent supervision and rapid guidance of vehicles, goods, and drivers. Through the information interaction between the radio frequency identification card installed in the vehicle and the radio frequency base station system, the vehicle can be accurately identified and the vehicle path monitored And status, and relying on the information management platform to issue supervision instructions in real time to realize the guidance and monitoring of vehicles.
2. Using 433 MHz and 920 MHz dual-band active RFID electronic tags, anti-collision performance can read 300 RFID cards at the same time, and the reading distance is up to 300 meters.
3. Realize vehicle non-stop supervision and intelligent inspection, which greatly improves the pertinence and effectiveness of inspection work.
