摘要
文章对船舶起货机系统进行PLC电气控制系统的设计,首先阐述了船舶起货机系统的结构和控制要求,并对控制系统进行了硬件设计,PLC控制器选用西门子公司的S7-200中的CPU224型号,再加上控制按钮和接触器线圈等组成控制回路,主回路由接触器主触点、断路器、熔断器、热继电器和电动机组成。在软件上通过STEP7-Micro/WIN软件对PLC进行编程,包含起货机启动、起货机停车和起货机逆转矩控制程序,完成了船舶起货机系统的PLC电气控制系统的设计。
This paper designs the PLC electrical control system for ship crane system,firstly it expounds the structure of ship crane system and control requirements,and designs the control system hardware,PLC controller chooses the Siemens S7-200 CPU224 model,combined with the control button and contactor coil control circuit,main circuit consists of contactor main contact,circuit breaker,fuse,thermal relay and motor.The STEP 7-Micro/WIN software is used to program PLC which contains the start,the crane winch parking and winch reverse torque control program,completing the PLC electrical control system for ship crane system.
