摘要
随着物联网技术广泛运用,智能家居以及智慧社区的开展,弱电控制器广泛应用于室内家用电器以及室内外传感器的控制。所设计的弱电控制器或通信模块的电源线或信号线易受到市电(220 VAC)的影响,从而导致电路后端芯片软损坏或直接损坏。设计了适用于智能家居控制系统后端控制器及通信模块中的低压保护电路。通过实验测试,进行直流过载以及交流干扰测试均具备电路保护作用。
As the Internet of things technology developed faster, smart home and the intelligence community are used, the weak current controller is widely used in appliances of the indoor household and control of the indoor and outdoor sensor. The design of weak current which is a controller or a power line communication module is easily affected by the mains （ 220V AC ）, and leaded to a backend chip circuit soft damage or direct damage. The design of circuit is suitable for the intelligent household control system controller and communication module in the back - end of the low voltage protection circuit in this paper. Tested through the experiment, which is tested by the DC load and AC interference, the design of the circuit is protected.
