摘要
在小型水电厂监控系统方案及其通信软件的设计中,采用2 级完全分布式监控方案,省去常规的当地控制单元(LCU)。监控IPC经CAN_BUS和RS485与具有不同通信协议的各种智能模块进行信息交互,监控软件的通信模块采用多线程技术有效地实现了人机交互及数据管理模块与通信模块分时多任务操作。给出了具体的实现方法。
In the design of the monitoring system scenarios and communication software of small-sized hydropower plant, two levels complete distributed monitoring scenario is adopted to leave out the conventional local control unit (LCU). The monitoring IPC interacts information with different intelligent modules of different communication consultative through CAN-BUS and RS485. And the multi-thread technique of the communication modules of the monitoring software effectively realizes the interaction between human and computer and time-sharing and multi-task operation of data management and communication modules. The implementation method of the design is proposed.
