近几年来无线通讯得到了快速发展,特别是GPRS的传输技术更加成熟完善。利用其无须再投资建设传输网络,且通讯覆盖范围大,安装调试方便,采用RS485现场总线并加装GPRS无线网络通讯系统组建成的控制系统,可实现对远程数据的监测与控制。本文介绍该系统在矿山配料站远程计量控制中的应用。1改造前设备状况某水泥生产线矿山配料站工艺流程见图1。矿山配料站控制系统框图见图2。 In recent years, wireless communications have been rapid development, especially GPRS transmission technology is more mature and perfect. Use it no longer need to invest in the construction of transmission network, and the communication coverage, installation and commissioning convenience, the use of RS485 field bus and GPRS wireless network communication system installed into a control system, enabling remote data monitoring and control. This article describes the application of the system in the remote metering control of the dosing station.
