【摘要】 针对传统楼宇单元配电系统网络布线困难、节点智能化程度不高等弊端,设计了基于无线传感器网络的楼宇单元配电箱改造控制系统.该系统硬件主要包括位于房间内部的信息接收盒和楼道间的开关主控制器,信息接收盒由电源部分、单片机部分、无线收发模块、信息存储模块、看门狗以及开关控制部分组成,开关主控制器由MSP430系列单片机、电源模块部分、按键、12864液晶屏组成,并且可通过RS232连接上位机电脑,信息接收盒分成4组分别连接到4个开关主控制器上,开关主控制器连接到值班室内的电脑;软件包括基于MODBUS协议的上位机通讯软件及监控软件.该系统中无线收发模块的有效范围达到1~2.5km,宿舍管理员能远程遥控各个房间的照明电路和插座电路,并且可以查看到任意房间的电路关断情况.更多还原

【Abstract】 For the drawbacks of difficulty in network cabling of the traditional building unit distribution system and low degree of the intelligence node, the transformation of a building unit distribution box control system based on wireless networks was designed. The hardware of the system included information receiver box inside rooms and the main controller switch located in corridor. The information receiver box consisted of power supply, micro controller unit, wireless transceiver, information storage, watchdog and switch control.The main controller switch consisted of MSP430 series micro controller unit, power supply, key module and12864 liquid crystal display screen, and was connected to personal computer by RS232. The information receiver boxes were divided into four groups respectively connected to four main controller switches, and then the main controller switches were connected to the computer in the duty room. The software included PC communication software and monitoring software based on MODBUS protocol. The dormitory administrator can remotely control the lighting circuits and sockets circuit of each room and check out the circuit in any room because of the effective range of a wireless transceiver module of the system reaching 1-2.5 km.更多还原
