Problems solved by technology

However, since the battery may be damaged or dead, or in the absence of a battery, the chip of the on-board unit cannot detect whether the on-board unit has been removed, and if the on-board unit is removed while the power is off, Stolen brush and reinstalled on the car window, since the tamper switch is pressed again after reinstallation, at this time, power on or replace the battery immediately, the vehicle unit still cannot detect whether it has been disassembled during the power outage
Therefore, a new technology is urgently needed to solve the problem that the vehicle-mounted unit cannot detect whether it is disassembled when the power is off.

Abstract

The invention provides an anti-disassembly self-destruction device applied to a vehicle-mounted unit and the vehicle-mounted unit. After the vehicle-mounted unit is disassembled, a second spring pushes a magnet block to pass through a coil winding area, a coil cuts a magnetic line of force to generate current, a chip arranged on a circuit board detects the current, and a self-destruction process is triggered, so that the self-destruction function of the vehicle-mounted unit is achieved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an anti-demolition and self-destruction device applied to a vehicle-mounted unit and the vehicle-mounted unit. Background technique [0002] With the popularization of the non-parking toll collection electronic system ETC, the on-board unit installed on the vehicle side is widely used. At present, in order to avoid the problems caused by the vehicle-mounted unit being disassembled from the vehicle window and then installed on other vehicles, it is necessary to install an anti-dismantle self-destruction device (such as an anti-dismantle push switch) on the vehicle-mounted unit to detect whether the vehicle-mounted unit is damaged. Disassemble. Specifically, the existing vehicle-mounted unit is usually powered by a battery, and the chip of the vehicle-mounted unit is connected to the battery and the anti-dismantle switch respectively. When the vehicle-mounted unit is installed...
