Electronic disassembling preventing method and electronic disassembling preventing system for electronic toll collection (ETC) electronic tags

Abstract

The invention relates to the field of electronic toll collection (ETC) electronic tags, in particular to an electronic disassembling preventing method and an electronic disassembling preventing system for ETC electronic tags. Disassembling prevention and thievery prevention are realized by binding the ETC electronic tags and trip computers of a vehicle one by one in an electronic authentication manner. The electronic disassembling preventing method comprises the following steps of: building a binding relation between the ETC electronic tags and the trip computers; performing disassembling information authentication between the ETC electronic tags and the trip computers when the ETC electronic tags are communicated with a charge terminal; returning a disassembling information authentication result, namely disassembling zone bit information, to the charge terminal by the ETC electronic tags; and judging whether the charge terminal transacts with the ETC electronic tags or not according to the disassembling zone bit information. According to an embodiment of the invention, the trip computers can be used for performing disassembling prevention and thievery prevention authentication on the ETC electronic tags, so that an accurate authentication effect can be achieved, and shortcomings of a mechanical disassembling preventing device are avoided.

Description

technical field [0001] The invention relates to the field of electronic non-stop (ETC) electronic tags, in particular to an electronic anti-disassembly method and system for an ETC electronic tag. Background technique [0002] With the increase in the frequency of use of electronic non-stop (ETC) electronic tag equipment, its anti-theft and anti-disassembly requirements are becoming more and more prominent. At present, there is no uniform method for anti-dismantlement of vehicle-mounted electronic equipment. Among them, the existing ETC vehicle-mounted electronic tags mainly adopt mechanical anti-dismantlement methods, such as reed switches and springs. electronic circuit connection. When the vehicle-mounted electronic tag is installed on the vehicle for the first time after it is issued, the vehicle-mounted electronic tag is activated, its tamper information bit is reset, and the mechanical device starts; when the vehicle-mounted electronic tag is disassembled, the mechani...

AI Technical Summary

Problems solved by technology

[0003] Vehicle-mounted electronic tags that use mechanical tamper-proof methods need to be activated again when they are repaired or replaced. The activation is generally performed in a professional operation network using an encrypted method, which is not conducive to the large-scale application of vehicle-mounted electronic tags.

At the same time, the mechanical anti-dismantlement method cannot be used when the vehicle electronic tag is knocked off artificially, and the reliability is insufficient.
