Embodiment 1

[0046] In this embodiment, the working state of the electronic tag is represented by one byte (eight bits) of disassembly information in the ESAM module, where the upper four bits are not specifically defined in the present invention (the default is 0000), and the lower four bits are The meaning is shown in Table 1:

[0047]

[0048] When the disassembly byte of the electronic tag is "00H" (H means hexadecimal data), it means that the tag has been disassembled; when the disassembly byte is "01H", it means that the tag is working normally.

[0049] In this embodiment, the unique identification number of the ETC vehicle-mounted electronic tag is: MAC address, which is 4 bytes of hexadecimal data, such as 00:00:00:01.

[0050] The processing steps of this embodiment are as follows:

[0051] 1. Before installing the ETC vehicle-mounted electronic tag, write the key information of the installed vehicle into the vehicle-mounted electronic tag, and the serial number of the ETC ve...

Abstract

The invention discloses a detaching prevention method for vehicular electronic tags. When in installation, a vehicular electronic tag is uniquely bound with a vehicle through a detaching preventer, wherein the vehicular electronic tag is installed at the vehicle. The detaching preventer is an integrated circuit of a fragile paper substrate. A chip connecting coil is arranged on the fragile paper substrate. After fragile paper is torn, the coil is broken and the circuit fails to operate. When the electronic tag is installed on the vehicle, the detaching preventer is also installed around the electronic tag, and the electronic tag and the detaching preventer mutually determine mutual verification codes by means of wireless communication. When collecting electronic toll, the vehicular electronic tag communicates with the detaching preventer first and allows for normal transaction after binding relation is confirmed. If the detaching preventer is broken, or the range between the detaching preventer and the electronic tag exceeds the set range and communication verification fails, the electronic tag is detached. By the method, such technical problems that the vehicular electronic tag is used or detached illegally and error prompts occur during using can be avoided effectively.

Description

technical field [0001] The invention relates to an application technology of a vehicle-mounted electronic label in an electronic toll collection system in the field of intelligent transportation, and more specifically, relates to a method for preventing disassembly of a vehicle-mounted electronic label. Background technique [0002] Electronic Toll Collection (ETC) system is an important application of Intelligent Transport Systems (ITS). The ETC system realizes billing transactions through wireless communication between the ETC antenna and the vehicle-mounted electronic tag. The communication protocol adopts the Dedicated Short Range Communication (DSRC) protocol, and the processing process is: ETC antenna (Road Side Unit, RSU for short) emits periodic downlink BST (Beacon Service Table, Beacon Service Table) signals, and when a vehicle equipped with an on-board electronic tag (or on-board unit, On-Board Unit, OBU for short) enters the ETC charging area, it will receive BS...
