摘要:
为了实现中央空调系统的远程监控,设计了一种实时中央空调系统远程监控软件.对中央空调控制系统进行研究,分析系统的功能需求,采用经典三层架构,基于Qt利用pvBrowser构建系统框架,采用矢量图形动画显示、多线程技术、数据库等技术,以及对BACnet协议应用层的研究开发,实现了对中央空调系统设备状态参数的远程实时显示功能、开关远程控制功能、上下警戒限报警功能和数据存储分析功能.设计完成的软件实用、高效、稳定,支持多种楼宇通信协议,其后续开发将使系统可以满足中小自动化集成商使用需求.%In order to achieve remote monitoring of central air-conditioning system,a real-time central air-conditioning system of remote monitoring software is designed.Based on functional requirements of analysis system,classic three-tier architec-ture is used on the system.The system adopted pvBrowser build system framework based on Qt.And vector graphics ani-mation display,multi-threaded technology,database and other technologies are also used in the system.The remote central air-conditioning system employer the BACnet protocol application layer to realize the system equipment status parameters display real-time memory analysis capabilities,remote control switch,the upper and lower limit of the warning alarm func-tion and data.Designed software is practical,efficient,stable,and supports a variety of building communication protocols, and its subsequent development will enable the system to meet the needs of small and medium automation integrators.De-signed software is practical,efficient,stable,and supports a variety of building communication protocols.And its subse-quent development will enable the system to meet the needs of small and medium automation integrators.
