基于LabVIEW的原煤仓清堵机远程监控与诊断系统设计

Design of remote monitoring and diagnosis system for coal bunker cleaning machine based on LabVIEW

针对电厂现用的原煤仓清堵机只能在煤仓现场使用的问题,设计了一种原煤仓清堵机远程监控与诊断系统;实现了对原煤仓清堵机远程操作与监控,同时还可兼容现有的现场模式。文中给出了由监控中心与PLC控制柜相结合构成的原煤仓清堵机远程监控与诊断系统的整体结构;基于LabVIEW设计了监控主机与原煤仓清堵机之间的数据交换方案及系统的故障诊断方案,可以很好地解决火电厂的自动化输煤问题。实际应用表明该系统在PC机上运行稳定,实现了对原煤仓清堵机的远程监测与综合诊断。

To solve the coal bunker unblock machine now using for power plant can only be used in the coal bunker site,a remote monitoring and diagnosis system of coal bunker unblock machine was designed.And a remote monitoring and diagnosis system of coal bunker unblock machine was realized.At the same time,the system can compatible with site mode existing.In this paper,general structure of remote monitoring and diagnosis system of coal bunker unblock machine composed of monitoring center and control equipments based on PLC was given.Main body of this article was designed a data exchange program between monitoring host computer and coal bunker unblock machine,as well as fault diagnosis program of system.It can solve the problem of thermal power plant coal handling automation.The actual application shows that the system runs stably on the computer and realizes real-time monitoring and diagnosis of coal bunker unblock machine.
