Anti-cracking controller for secondary water supply

Abstract

The invention discloses an anti-cracking controller for secondary water supply. The anti-cracking controller comprises a control box, a control circuit board, a control chip, a power connection module, a self-destruction signal trigger module, a distance sensor, a positioning block, a power trigger block and a storage battery. The control box comprises a box body and a box cover, and the control circuit board and the storage battery are both fixed in the box body. The control chip, the power connection module, the self-destruction signal triggering module and the distance sensor are all installed on the control circuit board, the power connection module is connected with the storage battery, and the self-destruction signal triggering module is connected with the power connection module, the distance sensor and the control chip; the positioning block and the power supply trigger block are both fixed on the box cover, the positioning block corresponds to the distance sensor, and the power supply trigger block is connected with the power supply connection module through a fixed-length connecting line. According to the invention, self-destruction of the chip can be realized when the control chip is reversely cracked, so that the purpose of effectively protecting information is achieved.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to an anti-cracking controller for secondary water supply. Background technique [0002] Secondary water supply refers to the form that units or individuals store and pressurize urban public water supply or water supply from self-built facilities, and then supply it to users or for their own use through pipelines. The secondary water supply is mainly established to compensate for the lack of pressure in the municipal water supply pipeline and to ensure the water consumption of the residents and people living in high-rise buildings. Compared with the raw water supply, the secondary water supply is more likely to be polluted due to the longer residence time of tap water in the water tank. [0003] In order to ensure the safety of the secondary water supply, people have developed a technology that can add sodium hypochlorite disinfectant in real time according...
