基于plc的电梯控制系统的设计本科论文

基 于 PLC 的 电 梯 控 制 系 统 的 设 计摘 要随着社会的进展，尤其是现代城市的建设高速进展所带来的高层建筑猛烈的增多，在高层建筑之间的垂直交通工具——电梯，对人们生活也就显得特别重要。在电梯出现的早期，其控制方式多为继电器控制方式，但这种控制方式有个致命的缺点——安全性差。随着微电子技术、计算机技术、和自动控制理论技术的进展，电梯的逻辑控制也由PLC 代替了原来的继电器控制，安全性、可靠性得到了质的飞越。本文针对六层电梯控制系统，对其PLC 系统的设计和调试进行了详细的阐述。 电梯是集机电一体的复杂系统，不仅涉及机械传动、电气控制和土建等工程领域，还要考虑可靠性、舒适感和美学等问题。而对现代电梯而言，应具有高度的安全性。事实上，在电梯上已经采纳了多项安全保护措施。在设计电梯的时候，对机械零部件和电器元件都实行了很大的安全系数和保险系数。目前由可编程序控制器(PLC) 和微机组成的电梯运行逻辑控制系统，正以很快的速度进展着。关键词：PLC 电梯 控制系统Design of elevator control system based on PLCAbstractWith the development of society, especially the construction of modern city brought by rapid growth of the high-rise building more violent, elevator also is especially important for the people life in the high-rise building of vertical transportation! In the early, when lift is invented, its control way is relay control way, but this kind of control mode has a fatal flaw-poor safety. With the development of microelectronics technology, computer technology, and automatic control theory, the logic of the elevator control is PLC instead of the original relay control, and it is safety , reliability are improved.In this paper, the design and debugging of PLC system are stated in detail in a storied building six elevator model control system. The core of the system control part is made of Mitsubishi operation cost. So PLC control technology has become a modern elevator control of a hot spot. The elevator is mechanical ...
