Problems solved by technology
It mainly involves the anti-disassembly scheme in the form of a micro switch. The disadvantage of this scheme is that there may be false indications, and the action stroke of the micro switch leads to a high height of the device, which makes it impossible for the active label to be miniaturized.

Embodiment Construction
[0049] Most of the existing anti-disassembly devices are set separately from the power-on device of the equipment where the anti-disassembly device is located (hereinafter referred to as equipment for convenience). In addition, when the device itself is disassembled, it needs to perform operations such as sound and light display, and write disassembly information to the security module, which requires continuous power supply. There is a design that uses large capacitor energy storage to continue the power supply after the micro switch is opened. However, this method has inherent disadvantages: large power consumption, especially when the temperature is high, the leakage current will increase, which is harmful to the use of batteries, etc. Power supply equipment has great hidden dangers; in addition, capacitive energy storage may not be able to meet the sound and light instructions and the operation of the safety module, so that the equipment is removed without recording.

The invention discloses a dismounting-preventing device and a dismounting-preventing method. The dismounting-preventing device comprises a microprocessor module, a gravity and dismounting detection module, a power supply module and a power supply control module. The gravity and dismounting detection module is used for sensing the acceleration of the equipment with the gravity and dismounting detection module on each dimension, converting the variation of the acceleration of the equipment on each dimension into the electrical signal and transmitting the electrical signal to the microprocessor module; the microprocessor module is used for judging that whether the variation of the acceleration of the equipment on each dimension reaches the acceleration threshold or not and controlling the power supply control module to stop supplying power to all the modules if the variation of the acceleration of the equipment on each dimension reaches the acceleration threshold; the power supply control module is used for controlling the power supply module according to the control of the microprocessor module so as to supply power to all the modules or stop supplying power; and the power supply module is used for supplying power to all the modules. To reduce the dismantling misjudgment to the maximum extent and avoid the real dismantling, the dismantling information does not need to be recorded, and the power consumption is not reduced.
Description
technical field [0001] The invention relates to the technical field of short-distance communication, in particular to an anti-disassembly device and a disassembly method. Background technique [0002] Electronic Toll Collection System (Electronic Toll Collection System, referred to as ETC system, also known as electronic toll collection system) uses Automatic Vehicle Identification (AVI) technology to complete the wireless data communication between the vehicle and the toll station for automatic vehicle identification and Regarding the exchange of charging data, the processing of charging data is carried out through the computer network to realize the full electronic charging system of non-stop automatic charging. [0003] ETC is an electronic automatic toll collection system for roads, bridges and tunnels that is being developed and promoted internationally. This technology has a long history of development in foreign countries. The electronic toll collection systems in th...
