陳中川(1985-),男,浙江溫州人,工程師,碩士,現(xiàn)就職于北京和利時智能技術(shù)有限公司,主要研究領(lǐng)域為工業(yè)控制器嵌入式軟硬件設(shè)計、控制系統(tǒng)設(shè)計與實現(xiàn)、自主可控PLC設(shè)計與開發(fā)等。
摘要:本文介紹了地鐵BAS系統(tǒng)的架構(gòu),分析BAS應(yīng)用場景對PLC的需求,并給出基于和利時LK系列大型PLC的地鐵BAS系統(tǒng)解決方案。以最具代表性的地下車站BAS系統(tǒng)為例詳細(xì)說明和利時LK大型PLC的現(xiàn)場總線和以太網(wǎng)解決方案、提出冗余的網(wǎng)絡(luò)結(jié)構(gòu)設(shè)計,通過綜合監(jiān)控系統(tǒng)和BAS系統(tǒng)協(xié)同配合共同完成對設(shè)備高效可靠的監(jiān)控。和利時LK大型PLC已在國內(nèi)外多條地鐵線BAS系統(tǒng)中得到應(yīng)用,其高性能、高可靠性、易使用、易維護等特性在地鐵BAS系統(tǒng)的應(yīng)用中得到廣泛的認(rèn)可。

Abstract: This article introduced the architecture of the subway BASsystem, analyzes PLC requirements of the BAS application, and proposedsolution for the subway BAS system based on Hollysys LK series large PLC.The most representative underground station BAS system is taken as anexample to explain in details Fieldbus and Ethernet solutions of LK PLC,and proposals of redundant network structure were illustrated. Throughthe cooperation of ISCS and BAS, the equipment can be implementedefficiently and reliably. Hollysys LK PLC has been applied in many subwayline BAS projects in China and overseas, with its high performance,high reliability, ease of use, and easy maintenance widely accepted bycustomers in subway industry.
Key words: Large PLC;Subway BAS;Underground station BAS;Redundancy
