基于JAVA的太阳能热水工程现场监控系统的设计

Design of Monitoring System for Solar Hot Water Project Based on JAVA

简述了太阳能热水监控系统的研究进展,针对目前太阳能热水器结构简单、监控系统不完善、现场控制管理混乱等问题,提出了基于Java平台的太阳能热水工程监控系统的设计方案,热水系统设计采用的控制单元主要有主控制器、输入输出模块、以太网通信模块;系统采用西门子系列的可编程控制器,通过搭建了OPC服务器,实现SCADA层与服务器间的通信,监控系统设计由设备层、现场控制层、通信层和服务器中心软件构成;设计的系统能够有效地对太阳能热水工程的现场进行实时监控,并可以实现数据信息的分析处理;通过对系统进行实际运行的测试,虽然实际精度值与采集值有微小的误差,但不影响整个控制系统的正常的运行;该系统可以实现有效的运行,具备数据采集、故障报警、数据分析等功能,提高了现场控制的准确性和精确性。

Research progress of the solar hot water monitoring system, aiming at the solar water heater has the advantages of simple structure, imperfect monitoring system, field control chaotic management, puts forward the design scheme of solar hot water project monito- ring system based on Java platform, a control unit with hot water system includes; the main controller, input and output module, Ethernet communication module. The system adopts the programmable controller of the SIEMENS series, by setting up a OPC server, realize the communication between the server and the SCADA layer, monitoring system designed by the equipment layer, control layer, communication layer and center server software. The designed system can effectively monitor the site of the solar hot water project and realize the analysis and processing of the data information. Through the actual operation of the system test, although between the actual accuracy and acquisition value exist a slight error, but does not affect the normal operation of the entire control system. The system can achieve effective operation, with data acquisition, fault alarm, data analysis and other functions, and improve the aceuracy of field control.
