Abstract

The invention belongs to the technical field of shell opening monitoring, and discloses a shell opening monitoring method, which adopts a monitoring system, and the monitoring system comprises a gear which is arranged in a shell, an adjustable resistor is arranged on the gear, and the resistance value of the adjustable resistor changes when the gear rotates; the rack is arranged on the cover, the rack can be meshed with the gear, and when the cover is opened or closed, the rack can drive the gear to rotate, so that the resistance value of the adjustable resistor is changed; the shell opening monitoring method comprises the following steps that whether an initial value needs to be reconfigured or not is judged; if reconfiguration is not needed, whether the current resistance value of the adjustable resistor is the same as the initial value or not is detected, if not, the cover is opened abnormally, and an abnormal state is marked; if so, entering a normal working mode; and if reconfiguration is needed, reconfiguration is carried out. Through the monitoring system and the monitoring method, whether the cover is opened abnormally can be determined, and the problem that other cover opening monitoring is easy to crack is solved.

Description

technical field [0001] The invention belongs to the technical field of shell opening monitoring, and in particular relates to a shell opening monitoring method. Background technique [0002] In order to prevent some criminals from stealing important data by disassembling the device, it is necessary to monitor whether it is opened by an illegal shell. At present, most of the shell opening monitoring on the market uses a single method, such as a mechanical button or a lighting method. [0003] However, when the case is not powered on, it is easy to find the corresponding countermeasures after opening the case for analysis. For example, pressing the unlocked switch or covering the photosensitive sensor and then powering on will cause the data protection method to fail. [0004] Therefore, there is an urgent need for a method for monitoring the opening of the casing to solve the above-mentioned technical problems. SUMMARY OF THE INVENTION [0005] Aiming at the shortcomings ...
