摘要
针对现有选煤厂PLC集中控制系统与现场设备之间采用有线通信方式,存在布线复杂、通信电缆损坏率高的问题,提出了一种基于无线通信的选煤厂PLC集中控制系统设计方案。该系统通过通信模块CP340和数传电台实现下位机控制总站S7-300PLC与ET200M分布式I/O分站之间数据的无线通信,解决了选煤厂通信线缆布线复杂、电缆损坏率高和检修维护不方便的问题,实现了选煤厂集中控制系统数据的无线通信。
In view of problems of complex wiring and high damage rate of communication cable existed in cable communication mode between PLC centralized control system of coal preparation plant and field equipment,a design scheme of PLC centralized control system of coal preparation plant based on wireless communication was proposed.The system uses CP340 communication module and data radio station to realize wireless communication between lower computer control station S7-300 PLC and ET200 M distributed I/O substation,solves problems of complex cable wiring,high cable damage rate and inconvenient maintenance of coal preparation plant communication, and realizes data wireless communication of centralized control system of coal preparation plant.
