基于电力线载波的LED消防指示灯的设计与实现

Design and Implementation of LED Fire Indicator Based on Power Line Carrier

设计的基于电力线载波的LED消防指示灯系统包括上位机、电力线载波模块、单片机最小系统和LED点阵显示模组等部分,采用电力线载波通信的方式将信号借助消防应急电源的专线传输到上位机系统,降低了施工的材料成本和人工成本。实验结果表明,系统可以动态显示,光流引导,有利于被困人员的识别,符合火灾现场被困人员的心理状态和思维能力,可以作为智能消防、应急、疏散控制系统的重要组成部分,集成到智慧消防系统解决方案中。

The system of power line carrier LED fire indicator system designed includes host computer, power line carrier module, SCM system and LED dot matrix display module and other components, in which the power line carri- er communication way is applied to transfer the signal to the host computer system with the aid of fire emergency pow- er line transmission, and the construction cost of material and labor cost is reduced. The experimental results show that, the system can dynamically display, guide by optical flow, conducive to the trapped personnel identification and conforms to the scene of the fire to the trapped personnel mental state and thinking ability, which can be used as an important part in intelligent fire, emergency and evacuation control system, integrated into the solution of wisdom fire protection system.
