基于CAN总线的DCS小型化控制系统设计

DCS miniaturization control system design based on CAN bus

针对一些中小型规模的工业现场运行状态的实时监测,设计了一种以CAN总线通信网络为基础的DCS小型化控制系统。介绍了充分利用其优势控制和监测各个节点状态,模块之间通过CAN总线网络进行数据通信,将监控数据传至上位机或上位机对现在监控节点进行控制和设置。系统设计简单,可靠性高,价格低廉。解决了传统DCS控制系统的组建复杂、成本高和小型PLC系统无法实现需求的情况下的中小型规模控制系统的难题。

For some small and medium-scale industrial site running real-time monitoring, is designed based on CAN bus minia-turization DCS control system, full use of their advantages to control and monitor the state of each node between them through the CAN bus network for data communications, monitoring data will be transmitted to the host computer or host computer right now to control and monitor the node set. Simple system design, high reliability, low prices. Realized in the form of traditional DCS system under complicated conditions and small PLC system is unable to complete the formation of the case.
