基于和利时LK大型PLC的地铁BAS系统设计与实现

Design and Implementation of Subway BAS System Based on Hollysys LK Large PLC

本文介绍了地铁BAS系统的架构,分析BAS应用场景对PLC的需求,并给出基于和利时LK系列大型PLC的地铁BAS系统解决方案。以最具代表性的地下车站BAS系统为例详细说明和利时LK大型PLC的现场总线和以太网解决方案、提出冗余的网络结构设计,通过综合监控系统和BAS系统协同配合共同完成对设备高效可靠的监控。和利时LK大型PLC已在国内外多条地铁线BAS系统中得到应用,其高性能、高可靠性、易使用、易维护等特性在地铁BAS系统的应用中得到广泛的认可。

This article introduced the architecture of the subway BAS system, analyzes PLC requirements of the BAS application, and proposed solution for the subway BAS system based on Hollysys LK series large PLC. The most representative underground station BAS system is taken as an example to explain in details Fieldbus and Ethernet solutions of LK PLC, and proposals of redundant network structure were illustrated. Through the cooperation of ISCS and BAS, the equipment can be implemented efficiently and reliably. Hollysys LK PLC has been applied in many subway line BAS projects in China and overseas, with its high performance, high reliability, ease of use, and easy maintenance widely accepted by customers in subway industry.
