应用于小水电的可编程控制装置的设计

Design of Programmable Controller in Small-Sized Hydropower Stations

采用模块化设计、总线结构研制适用于小水电站的可编程控制装置,进一步改善小型水电站的工作环境,提高其经济效益.该装置中设计了主控板、电源板、开入板、开出板和A/D板.主控板采用高性价比、低功耗的DSP56F807芯片,CPLD(复杂可编程逻辑器件)控制电路,提高了装置处理数据的速度和抗干扰能力.装置通过串口RS232、RS485与上位机通讯实现对装置的在线监控.

Modularization and buses are used in the design. The controller is used to improve the work- ing conditions in small-sized hydropower stations, and to attain higher economic benefits. The controller consists of the CPU, power unit, input board, output board, and A/D board. DSPSOF807 is used as the central processor, the CPLD （complex programmable logic device） controls the signals. The device communicates through RS232 and RS485. These improvements enhance the processing speed and resistance to disturbances.
