基于无线应急灯系统的通信协议设计

Design of Communication Protocol Based on Wireless Emergency Lighting System

为了克服传统消防应急灯设备工作独立非智能等问题,该文设计一种低复杂度的通信协议以适应应急灯状态信息的传输和汇总。该通信协议本身能够同时完成基站与上位机通信和节点间通信。该通信协议特点是有线、无线协调工作,拓扑结构固定,根据地理位置划分传输区域,同时其更具有实现方便,稳定性高,延迟时间短等优点。对这套通信协议的原理、架构以及在实际电路中的实现机制进行了说明及分析,并对现有无线应急灯系统进行了性能实验,证明其协议符合实际生产需要。

In order to overcome the difficult equipment installing and the non-intelligent problem of the traditional fire emergency lights,here the author embedded the wireless sensor network technology into the traditional emergency lights.The feature of this communication protocol is that it can work with wire or wireless,fixed with topological structure,and separating the transmitting area according to the location and also it has the advantage of convenient,high stability,time delaying,etc.This paper probes into the principle of this communication protocol,gives the explanation and analysis of the structure and the implementation mechanism in the practical circuit,also wireless emergency lighting system underwent the performance testing,which demonstrated protocol meets the production demands.
