基于以太网的煤量装载控制系统

Coal Loading Control System Based on Ethernet

设计了基于以太网的井下煤量装载控制系统。系统以地面工控计算机为主机,采用矿用本安型压力传感器采集质量信息,各路传感器将信号输入到分机,分机将处理后得到的煤炭质量等信息显示到液晶屏上。显示屏使用可触摸式液晶显示屏,触摸屏上增加设定报警值等功能,并且可以指示各组开关量信号。井下分机与地面工控计算机采用以太网通信的方式进行通信。系统的井下应用情况表明,使用该煤量装载控制系统大大减小了工作人员的操作难度,并且符合井下安全作业的条件。

An Ethernet-based underground coal loading control system was designed. The ground-based industrial control computer is used as the mainframe and the safety pressure sensors in mine are used to collect weight information. The signals are input to the extension by each sensor. The signals of the weight of coal obtained from extension are displayed on the LCD screen.Touchable liquid crystal panel is used as the screen. Functions are added to the touchable panel, such as setting alarm value and indicating the switching signal of each group. The Ethernet is used in communication between underground extension and the ground control computer. Through the down-hole application of the system, it is indicated that the coal loading control system has reduced the difficulty of operation for workers and the system also meets the standard of the down-hole safe operation.
