介绍了一种由一台计算机实时监控多台大功率开关电源的实现方案,采用了RS-232C和RS-485双串行通信总线标准接口,实现了计算机可以实时采样和设置电源输出电压、输出电流和各个开关量的状态。
A real-time monitoring of multiple high-power switching power supplies by a computer is introduced. The RS-232C and RS-485 dual serial communication bus standard interfaces are adopted to realize that the computer can sample and set the power output voltage, output current And the status of each switch.
