摘要
针对传统转子串电阻起重机调速性能较差,运行故障率高,维修复杂等特点,将可编程控制器(PLC)和变频器应用到港口门座起重机,重点介绍了控制系统的组成,硬件设计,软件设计和系统调试。最总实现港口门座起重机的变频调速性能,再通过PROFIBUS总线实现人机界面和PLC连接,可以实时监控起重机的运行故障和运行状态。实践表明,该系统可以广泛应用到门座起重机上。
The programmable controller （PLC） and frequency converter are applied to the door crane,it will realize the door crane frequency conversion control. Through the PROFIBUS realize human-machine interface and PLC connection, it can monitor crane operation failure. After the system is applied, it will improve the performance of the traditional portal crane, and improve the reliability of the portal crane.
