Exchanged the two speed elevator electricity control system mainly to use the programmable controller PLC technology.The PLC technology is many electrons which realizes with the microprocessor is the relay, the timer and the counter assembly, uses trapezoidal scheme programming which the electricity operator is familiar with, direct-viewing easy to understand. In interrogated importantly discusses the elevator following 3 characteristic: 1 security 2 completeness 3 to be possible to debug this three characteristic penetration entire design flow, was the entire design criterion. The design in may debug the aspect to manifest manifests importantly in divides to the elevator design into the sub-module, through to the module design and the debugging, reduced the design difficulty, enhanced the procedure readability and may debug Key Words: Programmable controller PLC completeness to be possible to debug 目 录 摘 要 I Abstract II 第一章 电梯控制概况 1 1.1引言 1 1.2电梯的发展前沿 1 1.3 PLC的设计优势 2 第二章 电梯基础知识 3 2.1电梯的基本结构和功能 3 2.2电梯的操作控制按钮简要分布 5 第三章 电梯的设计 5 3.1电梯的控制需要实现的功能 5 3.2电梯设计的模块划分 6 3.3电梯的平层、停层思想 6 3.4电梯的速度控制曲线 7 3.5 PLC的选型及I/O分布 7 第四章 梯形图设计 11 4.1电梯的开门环节 11 4.2电梯的关门环节 13 4.3层楼信号的产生与清除
