轨道交通隧道智能环境综合监测系统设计

Comprehensive Monitoring System Design of Rail Transit Tunnel Intelligent Environment

地铁隧道是城市轨道交通地下运行的主体环境,但隧道内的温度、湿度、可燃气体浓度(体积分数,全文同)等综合环境指标往往易被人们忽视.针对地铁隧道,设计城市轨道交通智能环境综合监测系统对隧道环境进行监测.采用无线多节点采集环境信息,节点采用STM32单片机控制,节点之间通过组网连接,可自由安装.每个节点带温湿度传感器、有害气体传感器、光学烟雾传感器等.每个节点布置一台数据接收器,收集所有节点数据并且处理显示.数据中心处理器由STM32芯片进行控制,通过单独采集到的数据进行集中运算处理.

Subway tunnel has become the main environment of the urban rail transit operation underground, but temperature, humidity, concentration of combustible gas and other comprehensive environmental indexes in the tunnel tend to be ignored. On account of subway tunnel, the comprehensive system of intelligent environment monitoring of urban rail transit was designed to monitor the tunnel environment. The wireless nodes were adopted to collect environmental information, controlled by STM32 SCM, connected by network and can be free installation. Each node is equipped with wind turbines, temperature and humidity sensor, harmful gas sensor, optical smoke sensor, etc. Each node arranges a data receiver to collect all node data and process and display. Data center processor was controlled by the STM32 chip,and centralized operation processing was conducted on the data collected separately.
