《基于六层电梯PLC控制系统》-毕业论文.doc

w w 摘 要 随着社会的发展，尤其是现代城市的建设高速发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发展，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。 本文针对某楼栋六层电梯模型控制系统，对其PLC系统的设计和调试进行了详细的阐述。其系统控制的核心部分是日本三菱公司制造的FX2NC系列的PLC，其控制适应性强、控制速度快、安装调试简便、运行费用较低，PLC控制技术已成为现代电梯控制的一个热点。 关键词：PLC 电梯 控制系统 Abstract With 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 Japan FX2NC series of PLC. PLC control technology has become a modern elevator control of a hot spot. The PLC control has strong adaptability，fast speed，simple installation, lower operation cost. So PLC control technology has become a modern elevator control of a hot spot.
