The transportation industry has become the most successful industry for RFID applications in China

As an automatic identification technology with multiple advantages, RFID technology has huge application potential in various industries, such as logistics, retail, medical, military, manufacturing, transportation, animal identification, coal mining and so on. But if I ask you a question, what is the industry that has the most successful RFID application cases, the most reliable application model, and the most mature technology in China? Did you know that the answer is the transportation industry. In foreign countries, because of the influence of Wal-Mart and the U.S. Department of Defense, the application of RFID in the retail industry and military has flourished. But in China, RFID World Net reporters found through multi-party investigation and analysis that the transportation industry is the most successful industry in China’s RFID industry.
RFID technology is widely used in China’s transportation. Successful application cases include: the largest domestic railway locomotive number recognition system (which has covered 18 railway bureaus and more than 70,000 kilometers of railway lines across the country),The non-stop toll collection system of networked expressways in the implementation and operation of various provinces (Note: Guangdong, Shanghai, Beijing, Chongqing, Fujian and other provinces and cities are in operation and implementation), thousands of parking lot RFID toll systems across the country, Factory vehicle automatic weighing system, bus station vehicle entry and exit management system, customs vehicle entry and exit inspection system, Beijing city automobile environmental protection inspection RFID environmental protection information card system (involving total vehicle capacity of 3 million vehicles), and in Hangzhou and Beijing Implementation of the rapid transit system.

The system characteristics of applying RFID in traffic vehicle management are as follows:
1. The application purpose of RFID is to identify the corresponding labeled vehicles: Realize the fine management of the vehicles by the management system through the recognition of the vehicles entering and exiting and passing by.
2. The system has high performance requirements for RFID tags:In order to reflect the advantages of the RFID system, it is generally required that the system can correctly identify the RFID tag at a higher speed of the vehicle. For example, the non-stop toll system generally requires the correct identification at a speed of 60 km/h, like the design performance of a railway car number recognition system The maximum recognition speed can reach 120 km/h. RFID technology can meet these requirements.
3. The system includes RFID technology of multiple frequency bands:For example, active 5.8GHz RFID technology and 13.56MHz RFID security consumer technology are integrated in the non-stop toll collection. The rapid transit system also uses 2.45GHz RFID technology, but the factory vehicle automatic weighing system can generally use 915MHz RFID technology.
4. RFID tags generally require tamper-proof:In order to realize one car one card (RFID tag), the RFID tag generally cannot be removed after being attached to the glass of the vehicle. Once removed, it cannot be used again.
5. The cost of RFID tags is relatively high, but it can be easily accepted when used in transportation systems: Because the value of the vehicle is high (tens of thousands or hundreds of thousands), even if the cost of an RFID tag is hundreds of dollars, it is still a small percentage by comparison. Therefore, the owner and the management department can accept this price for the convenience of traffic and fine management. .
6. The system generally does not need the anti-collision recognition function: RFID technology has a strong advantage of anti-collision recognition, which can read dozens or even hundreds of tags at the same time, but the result of reading may not reach 100%. This feature inspires people in the RFID industry to continuously improve, and at the same time brings constant troubles to the industry. Because it is difficult for most users to accept even a 99% recognition rate. In traffic applications, it is generally only necessary to read one car at a time. There is no requirement for collision avoidance, and a 100% reading rate can be easily achieved. This not only reduces the difficulty of system design, but also ensures the stability and accuracy of system identification. The successful application and promotion of RFID technology in transportation vehicles is not surprising.
At present, the dominant RFID hardware suppliers in the domestic transportation industry are Shenzhen Yuanwanggu, Shenzhen Xianshi Technology and Jiangsu Ruifu Technology, etc. Foreign companies include TRANSCORE, Tagmaster, etc.
RFID World.com believes that from the analysis of the current successful application of RFID technology in the domestic transportation industry, the successful promotion of RFID technology is ultimately a problem of ROI and a problem of reliable reading of the RFID system. It is wrong to talk about label cost, hardware cost, and system cost alone. It depends on how much benefit the RFID system can bring to the application, whether the supplier of each link of the system is mature, whether the system is stable, and finally the cost is the issue.
