基于ZigBee网络和M-Bus总线的热量表远程抄表方案设计

摘要

供暖行业中按住宅面积收费的计费方式很不合理,还会造成能源的浪费,采用热量表分户计量是解决这一问题的有效方法,而推行分户计量就必须解决热量表抄表的问题.针对热量表抄表系统存在的问题,设计了一套有线加无线的远程抄表方案.有线部分采用户用仪表总线M-Bus,无线部分采用ZigBee网络.描述了系统的3种设备---从机、集中器和管理中心的总体结构和工作流程.%The current charging mode of central heating industry is that the heating bills are collected according to the residential are-a. This mode is not very reasonable and results in great energy waste. Adopting household heat metering is an effective way which can be used to solve this problem. To carry out household heat metering, problems of meter reading should be solved. Aimed at problems existing in the current heat meter reading system, this paper presents a solution with bus wire and wireless network. M-Bus is used in the bus wire part and ZigBee wireless network is used in the wireless part.It also describes the structurer and working process of heat meter,concentrator and management center.
