基于LabVIEW的公共场所分布式节能监控系统设计

Design of distributed energy-saving monitoring and control system based on LabVIEW

分别对从站点、主站点以及上位机监控系统进行设计。从站点通过AT89S51单片机实时采集各房间电器设备状态信息,然后通过电力载波BWP09将信息传送给主站点;主站点采用双串口STC12C5A08S2单片机将接收的信息通过串口通信传送给监控主机;在监控主机上采用LabVIEW软件设计友好的人机交互监控界面,实时显示各从站点信息,并进行远程控制。该系统可以自动检测有无人员在办公场所,在没有人时自动切断电器设备的供电,减少电能的浪费,达到开源节流的目的。

The slave station, central station and upper PC of monitoring and control systems are designed respectively. The slave station collects electrical equipment state information of each room in real time through AT89S51 SCM, and then the information is transmitted to central station by electric power carrier BWP09. With STC12C5A08S2 SCM of dual serial port, the central station transmits the information into upper PC through serial communication. A friendly interactive interface is designed by LabVIEW software in upper PC, which can display the real time information from slave stations and achieve remote control. The designed system can automatically detect whether the staff members are in the office, and cut off the power supply of electrical equipment automatically without people, which can reduce the waste of electric energy and achieve the purpose of broaden sources of income and reduce expenditure.
