基于三菱PLC十层电梯控制设计
摘要
、井道、轿厢、门系统和电气控制系统组成。电梯已不仅是一种生产环节中的重要设备,更是一种工作和生活中的必需设备,完全可以预想到,随着社会的发展,电梯产品在人们物质文化生活中的地位将和汽车一样,成为重要的运输设备之一。
本次设计主要将可编程序控制器(PLC)和计算机应用到电梯的控制系统中去,以十层电梯为例来完成单台电梯PLC控制系统的总体设计方案、组成及模块化程序设计。选用三菱FX2N可编程控制器,利用220V交流电源供压。在进行PLC的I/O接口分配、组合排列和代号后,确定机内各种软继电器、数据区、通道代号,常用指令的编制规则和代号等。选用交流双速电机实现电梯拖动,采用楼层传感器实现楼层间翻转;显示驱动电路采用LED发光二极管构成显示屏的屏体。重点研究PLC的安全控制电路、楼层控制电路,开关门电路的设计,以及启动开关门程序、上行下行程序、楼层控制程序、自动定向程序的编写。PLC电梯控制系统只需要稍加改进即可应用于更高性能要求的电梯中。这一切都表明该系列PLC不仅可以满足电梯对高可靠性的实际需求,而且在控制水平和性能完全可以替代进口的同类产品,并将突破电梯领域应用到更为广泛的行业,未来前景将更为广阔。

Based on the Mitsubishi elevator control design of PLC ten

ABSTRACT
The elevator is the mechanical electric appliance close union large-scale mechanical and electrical products. Mainly of engine room, well road, sedan theater box, gate system and electric control position. The elevator already was not only in one kind of production link's important equipment, was in one kind of work and the life essential equipment, definitely might expect that along with society's development, the elevator product's will be the same in people material culture life status with the automobile, es one of important transport vehicles.
This design mainly (PLC) and puter applies the programmable controller in elevator's control system, as pletes the single Taiwan elevator PLC control system's overall project design, position and the modularized program design take five elevators. Selects the Mitsubishi FX2N programmable controller, After carrying on PLC the I/O connection assignment, bination arrangement and the code channel code number, commonly used instruction establishment rule and code number and so on. Selects the exchange two speed electrical machinery to realize the elevator dragging, uses the floor sensor to realize between the floor to turn over; The demonstration driving circuit uses the LED light emitter diode
