【摘要】：随着中国经济的高速发展,城镇化成为必然趋势,新型城镇建设给户用抄表行业带来机遇和挑战。科技的发展为远程抄表的实现提供技术支持,居民生活水平提高以及国家节能减排等政策对抄表系统有新的要求,但目前国内的远程抄表行业正在起步发展阶段,没有形成统一标准,不能满足当前城镇化发展需要。针对用户需求和目前远程抄表系统的不足,本论文重点从抄表数据传输方式,降低运营成本出发,设计了一种基于M-Bus总线技术和ZigBee无线网络技术的热量表远程抄表系统。本论文设计的远程抄表系统包括管理中心、ZigBee无线网络、集中器、M-Bus总线组成。首先,为了方便保存、处理抄表数据,本文采用VB6.0编写管理中心软件,完成用户信息登记、按户抄表、集中抄表、费用管理等可视化操作,利用Access数据库有效管理抄表数据；其次,管理中心与集中器之间通过无线局域网络传输数据,利用ZigBee技术组建无线局域网,设计无线局域网中的协调器、路由器、终端节点,采用低功耗MSP430F149和CC2420射频芯片,根据通信协议设计了无线拓扑结构、无线通信程序,确保数据准确、安全、实时传输；再次,集中器与热量表之间是通过M-Bus总线构成-主多从的通讯系统,根据M-Bus通信协议以及主从机调制方式设计了用于热量表的接口电路和供电电路,实现仪表数据不间断计量和实时抄表。实验表明：以楼宇内M-Bus总线通信和楼宇外ZigBee无线局域网通信结合的抄表系统,在确保数据安全可靠传输的前提下,有效降低运营成本和管理复杂度,具有很好的应用前景。
[Abstract]:With the rapid development of Chinese economy, urbanization has become an inevitable trend. The construction of new towns brings opportunities and challenges to the household meter reading industry. The development of science and technology provides technical support for the realization of remote meter reading. The improvement of living standards of residents and the national policies such as energy saving and emission reduction have new requirements to the meter reading system, but the domestic remote meter reading industry is in the initial stage of development, and there is no unified standard. It can not meet the needs of the current urbanization development. In view of the needs of users and the shortcomings of the current remote meter reading system, this paper focuses on meter reading data transmission mode to reduce operating costs. A heat meter remote meter reading system based on M-Bus bus technology and ZigBee wireless network technology is designed. The remote meter reading system designed in this paper includes the ZigBee wireless network of management center, the concentrator and M-Bus bus. Firstly, in order to save conveniently, the meter reading data is processed. In this paper, VB6.0 is used to compile management center software, user information registration is completed, meter reading by household, centralized meter reading, cost management, and so on, and Access database is used to manage meter reading data effectively. Secondly, the management center and concentrator transfer data through the wireless local area network, using ZigBee technology to build the wireless local area network, design the coordinator, router, terminal node in the wireless local area network. Using low power MSP430F149 and CC2420 RF chip, the wireless topology and wireless communication program are designed according to the communication protocol to ensure accurate, secure and real-time data transmission. Thirdly, there is a communication system between the concentrator and the calorimeter through M-Bus bus. According to M-Bus communication protocol and master-slave modulation mode, the interface circuit and power supply circuit for the heat meter are designed to realize the continuous metering of instrument data and real-time meter reading. The experimental results show that the meter reading system based on M-Bus bus communication in buildings and ZigBee wireless LAN communication outside buildings can ensure the safe and reliable transmission of data. The operation cost and management complexity are reduced effectively, which has a good application prospect.
