摘　　要：针对传统的大型公共建筑能耗采集系统难以融入当前的智能楼宇系统,并且不能有效处理能耗采集终端连接的问题,设计一种新型能耗采集系统。硬件设计以Cortex-M3处理器LPC1768为核心,以μC/OS-Ⅱ为操作系统,移植μC/TCP-IP协议栈,采用RS485和无线数据传输模块(WSN)实现终端连接,通过Internet与数据中转站通讯,并在此基础上用模块化思想进行系统软件设计。最后通过实例验证该系统融入当前智能楼宇系统的可行性及处理能耗监测终端连接的有效性。According to the problem that it is difficult to integrate the traditional large public buildings energy acquisition system into the current intelligent building and the system can not effectively deal with energy consumption acquisition terminal connection,a novel energy-consuming supervision system was designed. The system used the latest Cortex- M3 LPC1768 processor as the core. The μC / OS- Ⅱ was chosen as the software development platform. The μC / TCP- IP protocol stack was transplanted. The terminal connection was realized by using RS485 and Wireless Sensor Network（ WSN）. The system was communicated with the data conduit by using the internet. Based on μC / OS- Ⅱ and μC / TCP- IP,the software system with the modular method was designed. Finally,the feasibility of integration the monitoring system into the current intelligent building and the effectiveness of dealing with energy consumption monitoring terminal connection were verified by the real test.
