简述了数据电台的基本性能,并结合选矿工艺详细介绍了基于数据电台实现PLC与IPC构成的数据采集与监控系统。系统硬件主要采用全数字无线数传电台ND202A和西门子PLC构建无线通讯和数据采集系统,软件采用点对多点半双工通讯模式。该系统经济、可靠、易于扩展,实现了中心控制室与各PLC控制站之间的数据通讯和选矿过程的自动控制。
The basic performance of data broadcasting station is briefly described. The data acquisition and monitoring system composed of PLC and IPC based on data broadcasting station is introduced in detail in combination with beneficiation technology. System hardware mainly uses all-digital wireless data transmission radio ND202A and Siemens PLC to build wireless communication and data acquisition system, the software uses point to multi-point half-duplex communication mode. The system is economical, reliable and easy to expand. It realizes the automatic control of data communication and mineral processing between the central control room and each PLC control station.
