摘　　要：为了提高站点式光谱水质监测设备的供电可靠性,采用TPL521光耦作为掉电检测元件,以STM32为控制芯片,用继电器和三极管组成电源切换单元,设计了一套备份电源系统,并通过MATLAB搭建电源切换仿真实验对其可靠性进行了验证。结果表明:该备份电源系统可以满足大部分站点式水质监测设备的供电要求。In most of the site-type water quality monitoring equipment, the input power supply is only the mains power. When the mains power is abnormal, the control circuit of the equipment cannot get a stable power supply, which affects the normal operation of water quality monitoring. In order to improve the reliability of the site type spectral water quality monitoring equipment, TPL521 photoelectric coupler is used as the detection element for power loss, STM32 is used as the control chip, relay and triode are used as the switching power unit, a backup power supply system is designed, and its reliability is verified through the establishment of MATLAB power switch simulation experiment.
