Description

Technical Field

[0001] This utility model relates to the field of smart home controller technology, specifically to an anti-interference smart home controller. Background Technology

[0002] A controller is a master command device that controls the starting, speed regulation, braking, and reversing of a motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence. It consists of a program counter, instruction register, instruction decoder, timing generator, and operation controller. It is the "decision-making body" that issues commands, that is, it coordinates and directs the operation of the entire computer system.

[0003] Current smart home controllers often face the problem of insufficient anti-interference capability. When encountering strong electromagnetic interference, they may not work properly. When the input signal is interfered with, the controller will be unable to accurately process the signal and send instructions. If the output signal is interfered with, other connected devices will also lose their function. In severe cases, it may even lead to the paralysis of the entire system, resulting in economic losses and greatly affecting the user experience. To address this, we have proposed an anti-interference smart home controller. Utility Model Content
