2、,这种控制易出故障,维护不便,运行寿命短,占地空间大,正 逐步被淘汰。 为了提高自动控制系统的可靠性和设备的工作效率,设计了一套以PLC为核心控 制器的电梯自动控制系统,用来取代以往的较复杂的继电器接触器控制。系统的核 心部分(控制部分)使用了台达生产的DVP-EH型PLC,因为在核心控制部分采用的是 软件程序控制,从而在保证电梯正常运行这个要求的情况下,大大的提高了电梯故障 检查与维修的方便性和容易性,同时还克服了手动操作所带来的一些人为干扰因素, 取得了良好的预期效果。 关键词关键词:电梯;PLC;梯形图 指导老师签名指导老师签名 Design of elevator control sy
