基于GE PAC的多部电梯群控系统设计—软件组态 摘 要 随着越来越多的智能大厦拔地而起，电梯在智能建筑中的突出作用也更加被人们重视。现在的高层楼宇之中，往往需要装多部电梯群，这就需要对电梯进行联合控制，统一调度，提高电梯的服务质量和运行效率。因此，本课题研究的就是多部电梯的群控系统。 PLC又称可编程逻辑控制器，自诞生以来，就以可靠性而立足于控制行业，成为三大控制支柱之一。本课题使用的是GE公司的RX3i可编程自动控制器，相比传统的PLC，它更是具有可靠地控制效果，紧凑的模块化结构以及简便的程序化语言。此外，还用到了触摸屏以及iFix软件进行监控。本课题主要实现了对三部六层电梯的联合控制，依靠就近响应和优先响应的调度方法，实现了内呼优先外呼联控的最终效果。三部电梯之间的信号传输主要依靠现场总线的方式，具有准确，及时的优点。此外，触摸屏实现了对电梯运行的实时监控，画面中的软按钮也可以实现呼梯请求，多画面的切换可以更加详细的得知每部电梯的运行情况和呼梯请求。 总之，本课题具有控制稳定，反应快速，运行舒适，调度准确，画面清晰的特点，很好地符合了人们对现代电梯的要求。 关键词：群控系统，PAC，现场总线，触摸屏控制，组态控制 Multi Elevator Group Control System Design And Configuration Software Based On PAC Of GE ABSTRACT With more and more prominent role in Intelligent Building erected, elevator in the intelligent building is more and more attention by people. In the present high-rise buildings, there are often need to install many elevators group, which need to carry out joint control of the elevator, unified scheduling, improve the elevator service quality and operation efficiency. Therefore, this topic is to study multi elevator group control system. PLC also known as the programmable logic controller, since the birth of the reliability and based on the industry, become one of the three control pillars. This topic uses GE RX3i programmable automatic controller, compared with the traditional PLC, it is a reliable control effect, compact modular structure and simple procedural language. In addition, the touch screen and iFix software for monitoring. The ultimate effect of three six storey elevator control, rely on the nearest response and response to the priority scheduling method, realized the call priority outbound joint control have been realized in this paper. The signal transmission between the three elevators depends mainly on the field bus, and has the advantages of accurate and timely.. In addition, touch screen to achieve the real-time monitoring of the operation of the elevator, soft button screen can also achieve call request, the switching of mult
