摘要
针对音响播放系统等部分用电设备开机需要由前级设备到后级设备,关机需要从后级设备到前级设备,人工进行开关电源操作失误大且易造成用电设备损坏,通过STM32单片机控制、继电器切换、TFT液晶和LED显示、A/D采样、定时中断扫描等方法和手段实现了对电源时序的智能控制。整机控制稳定,操作简单,显示友好,具有较好的市场推广价值。
In view of the audio playing system and other electrical equipment start-up needs from the front-level equipment to the backlevel equipment,shutdown needs from the back-level equipment to the front-level equipment,manual switching power supply operation error is large and easy to cause electrical equipment damage,through STM32 MCU control,relay switching,TFT LCD and LED display,A/D sampling,timing interrupt scanning and other methods and means to achieve the power sequence intelligent control.The whole machine has stable control,simple operation,friendly display and good market promotion value.
