摘　　要：针对现代城市大型楼宇消防的高标准要求,基于物联网技术的无线消防应急灯疏散指示系统应运而生。以新型无线消防应急灯为硬件节点,将配套研发的无线通信协议和上位机软件相结合,从而构成一个完整的实验测试系统。为了测试该无线应急灯通信网络系统的性能,以小区单元楼为测试场地,分别对该网络系统的平均传输延迟、平均丢包率、节点信号强度和节点能耗进行数据收集和测试分析研究。测试研究结果表明随着楼层数的增加,平均传输延迟和平均丢包率指标增大,节点信号强度减弱,而且节点单位时间能耗能满足初步的应用需求。Aiming at fire control requirement with high level from large-scale modem city buildings, the wireless emergency direction light system based on technology of Intemet of things. Based on the hardware nodes of a kind of novel wireless fire- fighting emergency light, an integrated experiment system is designed by combing the developed wireless communication protocol and computer software. In order to test the performance of this wireless emergency communication network system, we collect data on average communication delay, average dropout rate, signal strength and energy consumption of light nodes, and analyze them. The study results show that average delay and average dropout rate become bigger as the number of building levels increases and the signal strength weakens. Finally, the energy consumption of unite time of nodes can satisfy the basic requirement from application.
