针对地源热泵群监控系统自动化的问题，提出了一种基于PROFIBUS-DP总线和组态软件技术的地源热泵群监控系统设计方案。系统以装有WinCC控制软件的PC机监控整个网络，一台S7-300PLC作为整个网络的主站，每个从站利用S7-300PLC实现对各个热泵机组的运行控制。该系统具有可靠性高、可维护性强、监控界面形象配置更容易、画面效果更逼真，程序运行更安全等优点。测试组实验结果证明：该设计能够满足监控系统的指标要求，能够很好地完成对地源热泵群工作温度等参数的监控任务。“,”To solve the issue of automatic monitoring system for ground source heat pump group,a monitoring system based on PROFIBUS-DP and configuration software technology is put forward in this paper. The system monitors the entire net-work with a PC equipped with WinCC control software. A S7-300 PLC serves as the master station of the whole network. Each slave station makes use of S7-300PLC to control all heat pump units. The system is characterized by high reliability,perfect maintainability,easier image monitoring interface configuration,more vivid pictures,safer program running,etc. Experimental results of the test group show that the design is able to meet the requirements of all indexes of the monitoring system,and can fulfill the mission of monitoring the working temperature of ground source heat pump group.
