Design of distributed control system of power supply of the telecommunication

This paper presents a design of distributed control system (DCS) of power supply of the telecommunication (PST), including the hardware structure and the design of software. The industrial computer is used as the supervisor computer to supervise and coordinate every supervising module. The supervising module is made up of MSC1210, a microcontroller made in Texas Instruments Incorporated (TI), which performs the measurement and control of the power supply system and rectifier system. It also communicates with the supervisor computer. The reliable communication between computer and many microcontrollers has been realized. The system can run for a long time without on duty.
