针对继电器控制系统可靠性较差、使用不够灵活方便等缺陷,利用PLC进行设计,达到了控制生产线的分拣、传送及进出库的目的。在系统中充分利用PLC在控制方面的卓越性能和变频器原理,用交流变频变压拖动技术,实现了生产线的启动平稳、运行可靠、故障率低的功能。在上位监控系统的设计中,利用组态软件设计了参数设置、过程监控、数据处理、故障定位等功能,对于今后基于PLC的工业控制设计具有一定作用。
For the relay control system reliability is poor, the use of less flexible and convenient defects, the use of PLC design, control of the production line to achieve the sorting, delivery and import and export purposes. PLC in the system to take full advantage of the excellent performance in control and inverter principle, with AC variable frequency variable drag technology to achieve a smooth start of the production line, reliable operation, low failure rate. In the design of supervisory control system, the functions of parameter setting, process monitoring, data processing, fault location and so on are designed by the configuration software, which will play a certain role in the design of industrial control based on PLC in the future.
