电梯PLC控制策略及其程序设计

指出了在PLC中采用布尔逻辑实现电梯复杂控制功能的缺点，结合电梯的控制要求和PLC的功能特点，开发出用PLC实现按人的思维、记忆和判断习惯控制电梯的控制策略，给出了其控制程序。该程序完全采用模块化结构，模块问耦合程度低；程序通用性强，适用于任何规模的电梯控制系统；程序逻辑简单，语句少，设计、调试、修改、阅读方便。

A new PLC-based elevator control strategy and the programming

The shortcomings in using Boolean logic to realize complicated elevator control functions are pointed out Combining the control request of elevator and the function characteristics of PLC,the control strategy based on PLC and peopleDK]'s thinking, memory and judgment habit is developed and the control program is designed.The program features:complete modular structure and low coupling degree between modules;versatility and suitable for any scale elevator control;simple program logic and less sentences and easy to design,bug ,modify and read.
