　　Application of RFID technology in ETC system

　　ETC is an advanced charging method that is currently being respected by all countries in the world. The car owner only needs to install RFID electronic tags on the car windows. When the vehicle passes through the toll station, the reader can read and write the RFID electronic tags of the passing vehicle through the toll station, and automatically read and write from the pre-bound radio frequency card or bank The corresponding fees are deducted from the account, and the toll station can be quickly passed through without the owner's parking and manual payment, and the road is truly smooth.

　　The ETC system is mainly composed of an automatic vehicle identification system, a central management system and other auxiliary facilities. Among them, the vehicle automatic identification system is composed of OBU, RSU, loop sensor and so on. OBU (Electronic Tag) stores the relevant information of the vehicle and is generally installed on the front windshield of the vehicle. The RSU (ie, reader) is installed next to the toll station. The loop sensor is installed under the road surface. The central management system stores a large amount of information about registered vehicles and owners. When the vehicle passes through the toll gate, the loop sensor senses the vehicle, the RSU sends out an inquiry signal, the OBU responds, and conducts two-way communication and data exchange. The central management system obtains the vehicle identification information and compares and judges, and controls according to different situations. The management system generates different operations to realize the automatic management of moving vehicles.

　　The popularization of RFID is in line with the trend of automobile intelligence and networking. RFID is based on the extension of the Internet of Things to smart transportation; the reason is similar to today’s face recognition, people don’t need to take out their ID cards and scan the faces to identify them. Personally identifiable information. How does RFID differ from ETC

　　Many people will confuse ETC with RFID. Although various places have been vigorously working to increase the installation rate of ETC, there are many essential differences between the two. In order to facilitate everyone's understanding, the following introduces the differences between ETC and RFID.

　　1. The standard setting departments of the two are different

　　In fact, RFID is not a particularly new thing. As early as the National Games, in order to ensure the fast passage of service vehicles, the installation of RFID, that is, the automotive electronic identification system, was used to realize the rapid passage of service vehicles. RFID is a passive electronic card containing a radio frequency chip, which can be installed on the windshield of a car and used for car identification, which is equivalent to a car's electronic ID card. The biggest difference between RFID and ETC is that the former is a standard specification for vehicle management and control led by the Ministry of Public Security; the latter is a non-stop electronic toll collection system for the main purpose of the Ministry of Transport to realize the non-stop toll collection of expressways. the difference.

　　2. There are big differences in application scenarios

　　ETC is not unfamiliar to most people. The most basic function is that highways can realize non-stop toll collection. With the access of Internet companies, ETC now also has payment functions such as parking, car washing, and refueling, but its core The function of the highway is still non-stop toll.
