摘要
针对继电器控制的大型砂轮成型设备,1600吨液压机电气线路复杂和故障率高的状况,采用三菱FX2N系列的可编程逻辑控制器对原有的继电器控制系统进行改造,以软继电器的逻辑运算取代传统继电器的硬线连接;运用PLC的顺序控制设计法,并按照工艺流程,以输出元件的变化设计控制功能图和梯形图,简化了线路;采用硬件软件双重联锁提高了控制系统的可靠性。
In order to remedy the complex electrical circuits and high failure rate with the large wheel molding equipment of 1600 tons hydraulic pressure machines, which were controlled by relay, MITSUBISHI FX2N programmable logical controller was adopted to replace the original relay control system. The traditional relay＇s hard-wired connections were replaced by logical operation of soft relay. What＇s more, PLC sequential control method was adopted and circuits were simplified by changing design control function diagram and ladder chart of the output components according to the technological process. The reliability of the control system was improved with double chain of hardware and software.
