摘要
随着计算机控制技术的迅速发展,以微处理器为核心的可编程序控制器已逐步取代继电器,普遍应用于各行各业的自动化控制领域。主要探讨了西门子公司的S7-300系列PLC及其网络技术在西安地铁二号线空调水系统中的应用,详细阐述了地铁空调水系统的控制策略,并着重介绍了变流量控制在本系统中的应用。已在西安地铁实际工程项目中成功应用,取得了良好效果。
With the rapid development of computer control technology, the microprocessor as the core programmable logic controller has gradually replaced relays, commonly used in the field of automatic control in all walks of life. This paper mainly discusses the application of the Siemens＇s PLC and network technology in air conditioning water system of No. 2 Xi＇an Metro Line, elaborates the components and control strategy of the air conditioning water system, and focuses on the application of variable flow control in the system. The control system has been successfully applied in the actual project of Xi＇an subway, and achieved good results.
