摘　　要：本文所设计的系统由上位机(手机)和下位机(故障设置箱)组成,其中故障设置箱包含蓝牙模块、MCU和继电器控制模块三部分。手机APP生成故障设置指令,蓝牙模块接收故障设置指令并传送给MCU,三极管9015再将MCU输出的数字逻辑信号放大,触发继电器切断信号,从而模拟故障发生。系统交互性好,可实现无线操控,具有一定的应用价值。The system is composed of upper computer(mobile phone)and lower computer(fault setting box).The fault setting box includes Bluetooth module,MCU and relay control module.The mobile app generates the fault setting instruction,and the Bluetooth module receives the fault setting instruction and transmits it to the MCU.The triode 9015 amplifies the digital logic signal output by the MCU and triggers the relay cut-off signal to simulate the fault.The system has good interactivity,can realize wireless control,and has certain application value.
