基于PLC和组态软件的运料小车监控系统设计

Design of carriage monitoring system based on PLC and configuration software

针对当前运料小车在应用过程中自动化程度较低的现状,通过PLC控制运料小车的运行,取代了传统的继电器控制,并结合组态软件设计了一种新型运料小车监控系统。该系统由上位机和下位机组成。上位机采用力控组态软件开发监控界面,下位机采用西门子PLC完成控制功能,上、下位机之间通过RS232进行通信。分析了系统的总体设计方案,阐述了软硬件系统设计,进行了组态软件动画界面设置。实践证明,基于PLC和组态软件的运料小车监控系统安全、可靠、维护调试方便,具有很高的推广价值。

For the current transportation status of the lower degree of automation in the carriage during the application process, through PLC control carriage, replacing the traditional relay control and design of a new type of carriage monitoring system based on configuration software. The system is made up of upper and lower computer. The upper used configuration software development monitoring interface, and the lower complete control based on Siemens PLC, between the upper and lower computer through RS232 communication. This paper introduces the design method of carriage monitoring system based on PLC and configuration software, analyzes the design scheme of overall program, and expounds the design method of software and hardware and set up the animation interface based on configuration software. The experiment results show that the carriage monitoring system, which based on PLC and configuration, have features of safety, reliably, maintenance and debug, it possessed of fine promotional value.
