【摘要】：隨著中國經濟的高速發(fā)展,城鎮(zhèn)化成為必然趨勢,新型城鎮(zhèn)建設給戶用抄表行業(yè)帶來機遇和挑戰(zhàn)�？萍嫉陌l(fā)展為遠程抄表的實現提供技術支持,居民生活水平提高以及國家節(jié)能減排等政策對抄表系統有新的要求,但目前國內的遠程抄表行業(yè)正在起步發(fā)展階段,沒有形成統一標準,不能滿足當前城鎮(zhèn)化發(fā)展需要。針對用戶需求和目前遠程抄表系統的不足,本論文重點從抄表數據傳輸方式,降低運營成本出發(fā),設計了一種基于M-Bus總線技術和ZigBee無線網絡技術的熱量表遠程抄表系統。 本論文設計的遠程抄表系統包括管理中心、ZigBee無線網絡、集中器、M-Bus總線組成。首先,為了方便保存、處理抄表數據,本文采用VB6.0編寫管理中心軟件,完成用戶信息登記、按戶抄表、集中抄表、費用管理等可視化操作,利用Access數據庫有效管理抄表數據；其次,管理中心與集中器之間通過無線局域網絡傳輸數據,利用ZigBee技術組建無線局域網,設計無線局域網中的協調器、路由器、終端節(jié)點,采用低功耗MSP430F149和CC2420射頻芯片,根據通信協議設計了無線拓撲結構、無線通信程序,確保數據準確、安全、實時傳輸；再次,集中器與熱量表之間是通過M-Bus總線構成-主多從的通訊系統,根據M-Bus通信協議以及主從機調制方式設計了用于熱量表的接口電路和供電電路,實現儀表數據不間斷計量和實時抄表。 實驗表明：以樓宇內M-Bus總線通信和樓宇外ZigBee無線局域網通信結合的抄表系統,在確保數據安全可靠傳輸的前提下,有效降低運營成本和管理復雜度,具有很好的應用前景。
[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.
