摘要
该系统是以某大型建筑中的五台溶液调湿空调机组为监控对象,以采集空调机组主要参数和实时数据为目的,而设计的一套基于Modbus现场总线协议的监控系统。本系统能精确的采集下位机上传的实时数据,并利用ActiveX中的TeeChart控件描绘出实时数据曲线;实时数据能通过数据库实现存取,数据库的存储周期为1年,数据库可以通过选取时间段的方式查询历史数据并绘制历史数据曲线。该系统总体实现了实时数据采集、存储、查询以及空调机组远程控制的功能。
The system is a large building of five solution wet air conditioning units for monitoring object, by collecting air conditioning unit main parameters and real-time data for the purpose, and design a set of Modbus fieldbus protocol based on the monitoring system. This system can accurately under a collection on the real-time data, and use the TeeChart ActiveX control describes the real-time data curve; Real-time data can be realized through the database access, database storage period for one year, the databa-se can be selected by way of historical data query time and draw historical data curve. The system overall realize the real-time data acquisition, storage, query and air conditi-oning units remote control function.
