基于电力载波通信的应急通道指示灯系统

Emergency channel indicator based on power line carrier

近年来,建筑楼宇的建筑面积不断增大,结构越加复杂,楼道内应急通道指示灯已经成为现代建筑内不可或缺的一部分。国内现有的应急通道指示灯以独立控制型为主,由于建筑内的指示灯数量庞大,给管理和维护带来了很大的困难。同时,此类应急通道指示灯无法在紧急情况发生时进行实时调整,优化逃生指引路线。本文提出了一套基于LonWorks电力线载波通信的应急通道指示灯控制系统,利用建筑内已有电力线作为通信信道而无需架设专用通信线缆,实现了对指示灯的统一管理、控制与检测。

In recent years, the area of constructions and their complicity are continuously rising, which give rise to the appearance of emergency channel indicators. Most of the emergency channel indicators in domestic buildings are independently controlled. The large amount of indicators in the building arouses problems on how to control and maintain them. Meanwhile, these kinds of indicators are nonadjustable according to the circumstances in real time when accidents happen. This paper presents a system of emergency channel indicator based on LonWorks power line carrier which controls the management and maintenance of the indicators communicating by exiting power lines rather than specialized cables in the building.
