基于物联网的智慧楼宇集散型应急灯自动控制系统

Intelligent Building Distributed Emergency Light AutomaticControl System Based on Internet of Things

传统应急灯仅可在火灾发生时起到照明作用,且均独立供电,维护困难,响应时延高,为此,设计了一种基于物联网的智慧楼宇集散型应急灯自动控制系统。基于物联网架构,包括感知层、控制层、应用层与网络层。将单片机当成核心,通过不同照明终端、传感器与网络通信端构成智能硬件与网关,对应急灯亮度、颜色进行智能控制,利用ZigBee技术完成远程控制。系统支持多种通信协议,利用ZigBee协议对物联网网关进行设计,完成多个协议互换,并支持多种传感器。硬件设计主要设计应急灯模块与控制模块。软件设计从应急灯与主控器两个角度进行设计,并设计协调器和上位机间的通信协议。实验结果表明,系统通信性能强,可针对智慧楼宇的紧急情况进行快速响应,整体性能强。

The traditional emergency lights can only play the role of lighting in case of fire,and they are all independent power supply,difficult to maintain,delayed response time.Therefore,a distributed emergency light automatic control system based on the Internet of things is designed.The design system is based on the basic Internet of Things architecture,including the perception layer,control layer,application layer and network layer.Taking SCM as the core,the intelligent hardware and gateway are constructed by different lighting terminals,sensors and network communication terminals to intelligently control the brightness and color of the emergency lights,and uses ZigBee technology to complete the remote control.The system supports a variety of communication protocols.ZigBee protocol is used to design the gateway of the Internet of Things,to complete the exchange of multiple protocols,and to support a variety of sensors.In hardware design,emergency light module and control module are mainly designed.The system software is designed from two aspects of emergency light and master controller,and the communication protocol between coordinator and host computer is designed.The experimental results show that the system has strong communication performance,can respond to the emergency of intelligent building quickly,and has strong overall performance.
