大型公共建筑(群)能耗监测系统 设计（下位机） 摘 要 由于现在国内外能源消耗很大，特别是城市公共建筑这类人口密集的地方，对能耗要求很高，建筑能耗管理显得极其的重要。针对这个问题，本课题设计了能量监测系统对建筑能耗进行监控，以达到调节和节约能源的目的。 该系统由上位机和下位机组成，本文提出了整体设计方案，并着重介绍的以Rabbit 2000微处理器为内核的RCM 2200单片机的组成以及其外围接口电路的设计，并给出了软件设计的主要框架。 该系统在硬件上可以实现的功能有数据采集，控制输出，串行通信（使用RS-232标准通讯），以太网通信。软件使用Dynamic C编程，下位机通过以太网口挂接在现场网段，作为主站控制器，通过以太网通讯口完成各个从站的网络通讯管理；作为从站或冗余站，通过以太网通讯口接收主站调度。各个节点都有RS-232串行通讯接口。串行通讯接口用于本地监控和组态，支持Modbus/RUT通讯协议。 关键词： 大型公建；能耗监测；嵌入式系统；工业以太网； Design of Energy Consumption Monitoring System (Slave Machine) in Large Public Bulidings Abstract Significant energy consumption at home and abroad now, in particular, the densely-populated areas of large public bulidings, have great demand on energy consumption. So I design energy consumption monitoring system to monitor the buliding energy, to reach the purpose of energy regulation and conservation. The system is made up of the PC and the slave machine, the design is presented in the paper and focused on the RCM 2200 module, which is based on the Rabbit2000 (the microprocessor core). The design of its external interface and the main framework of software are also presented. Some functions are achieved in the system in hardware, such as data acquisition, control output, serial port communications (based on the RS-232 communications standard) and Ethernet communications. The programming is based on Dynamic C software. The controller articulates in the scene of the network over the Ethernet interface, working as a main station controller, the controller can complete the network communications management by the Ethernet interface; as redundant station or slave stations, the controller accepts master scheduling over the Ethernet interface. The RS-232 serial communication interface is assembled in the station. Serial port communication interface for local monitoring and configuration and Modbus / RUT communication protocol is supported.
