【正文】 PLC的硬件資源和軟件資源，充分利用各種指令的簡化控制程序，做到控制程序應盡量簡單，便于理解，并有一定的規(guī)律性以便能適合于不同控制樓層的要求， 使電梯達到較為理想的控制效果。本次設計采用三種控制方式 :乘客操作方式 、 司機操作方式和手動檢修方式 。 關鍵詞 :電梯 ； PLC； 控制梯形圖 ； 程序 鹽城工學院本科生畢業(yè) 設計說明書（ 2020） Design on The sixstorey elevator PLC control system Abstract: With the highspeed development of China39。s lives are closely linked, are playing an increasingly important role with the advancement of technology, Research Programmable Logic Controller (PLC) in the elevator on the use of control is a very meaningful task. The design of content for the use of Programmable Logic Controller (PLC) control in a sixstory of passenger elevator. The main purpose is to solve some problems of the existing elevator control, the rational use of PLC hardware resources and software resources Make full use of all the mands simplified control procedures, the control procedures should be done as simple and easy to understand And with some regularity in order to be tailored to different floors control of the calls that lifts quite satisfactory control results. In the design process through to lift the input and output nodes statistics to select appropriate models PLC During the software design of PLC control system, first of all , lift the whole control process deposition, it is divided into several different modules, then design for these modules Respectively, and finally regrouped together into a prehensive control system .The designs of used three control modes : passengers operation mode, the driver and manual mode of operation maintenance mode. And pared to the previous, the design of the lift with high reliability, control procedures simple and input and output terminals use fewer features.
