【摘要】：当前的中央空调系统大多以分散控制为主,每个房间的温控器只能控制本房间风机的运行状态,显然不利于实现系统的整体智能管理及降低系统能耗。随着嵌入式技术和网络通信技术的不断发展,市场上出现了许多性能更高、价格更低的新型单片机芯片,同时网络通信的可靠性、实时性也越来越高。将这些新型芯片和先进的网络通信技术应用到远程监控系统,可以有效地提高系统的性能。论文基于ZigBee和Web技术研究中央空调远程集中监控系统的设计问题。该系统是基于B/S架构模式的远程监控系统,系统将数量众多的风机盘管等末端设备纳入统一管理。用户可以通过浏览器与系统进行远程交互,对系统进行及时、有效的监视与干预,从而达到降低系统能耗、减少浪费的目的。在系统的现场监控部分,采用增强型STC 51单片机设计了实现与以太网连接功能的智能网关和分布于各个房间的智能温控器,给出了电路结构图。智能网关采用ENC28J60以太网控制器实现以太网接口,使得在楼宇分布较分散的情况下,系统状态数据也可以上传到监控平台,实现多套空调系统集中远程实时监控。智能温控器负责采集房间内的实时温度和风机运行状态数据,并能根据用户设定温度依据先进的控制逻辑或监控平台下发的控制命令,对风机运行状态进行实时控制,实现系统节能降耗的目的。采用TI公司的CC2530系列ZigBee芯片设计了在智能网关与智能温控器之间无线数据传输网络,实现了楼宇内实时可靠的无线数据传输。采用JSP、AJAX等技术设计了 Web服务程序,为用户和系统之间的交互提供了统一、简洁和美观的接口,使用户通过浏览器即可登录系统并对系统的运行状况进行实时监视和控制。使用MYSQL数据库技术实现了系统运行数据的持久化存储,用户可以随时查看历史数据。编写了系统自动监控的应用程序,使系统可以在无人员干预的情况下,运行在合理的状态,及时消除系统中可能存在的电能浪费现象。最后对研究工作进行了总结,并指出了未来的研究工作方向。
[Abstract]:At present, most central air conditioning systems are mainly controlled by decentralized control, and the temperature controller in each room can only control the running state of the fan in this room, which is obviously not conducive to realizing the overall intelligent management of the system and reducing the energy consumption of the system. With the development of embedded technology and network communication technology, many new single-chip chips with higher performance and lower price have appeared in the market. At the same time, the reliability and real-time performance of network communication are becoming more and more high. The application of these new chips and advanced network communication technology to remote monitoring system can effectively improve the performance of the system. Based on ZigBee and Web technology, the design of central air conditioning remote centralized monitoring system is studied in this paper. The system is a remote monitoring system based on B / S architecture. The system brings a large number of fan-coil units and other terminal equipment into unified management. Users can interact remotely with the system through the browser, monitor and intervene the system in time and effectively, so as to reduce the energy consumption and waste of the system. In the field monitoring part of the system, an intelligent gateway with Ethernet connection function and an intelligent temperature controller distributed in each room are designed by using an enhanced STC 51 single chip microcomputer. The circuit structure diagram is given. The intelligent gateway uses ENC28J60 Ethernet controller to realize Ethernet interface, which makes the system state data can be uploaded to the monitoring platform under the condition that the building distribution is more dispersed, and the centralized remote real-time monitoring of air conditioning system can be realized. The intelligent temperature controller is responsible for collecting the real time temperature and the running state data of the fan in the room, and can real-time control the running state of the fan according to the advanced control logic or the control command issued by the monitoring platform according to the user set temperature. The purpose of energy saving and consumption reduction of the system is realized. The wireless data transmission network between intelligent gateway and intelligent thermostat is designed by using CC2530 series ZigBee chip of TI Company, which realizes real-time and reliable wireless data transmission in buildings. The Web service program is designed by using JSP,AJAX technology, which provides a unified, concise and beautiful interface for the interaction between the user and the system. The user can log on to the system through the browser and monitor and control the system's running condition in real time. MYSQL database technology is used to realize persistent storage of system running data, and users can view historical data at any time. The application program of automatic monitoring of the system is written so that the system can run in a reasonable state without personnel intervention and eliminate the possible power waste phenomenon in the system in time. Finally, the research work is summarized and the future research direction is pointed out.
