摘要
针对公路隧道预警系统与通风控制系统的实时数据需求,提高现有监控系统的实时性与集成度,设计了基于通用分组无线业务(GPRS)的公路隧道运营环境感知系统。系统以STM32为核心,集中采集并处理有害气体、温度与气压、能见度与风速信息,并由GPRS模块上传服务器,由监控中心上位机获取、处理分析运营数据。实验结果表明:本系统运行稳定,准确度较高,可以达到设计要求,对保障公路隧道运营安全具有积极意义。
Aiming at real-time data requirements of highway tunnel early warning system and ventilation control system,the real-time and integration degree of the existing monitoring system is improved,and the road tunnel operation environment awareness system bases on general packet radio service(GPRS)is designed.The system uses STM32 as the core to collect and process harmful gas,temperature and air pressure,visibility and wind speed information,then upload to the server by GPRS module.The upper personnal computer(PC)of the monitoring center obtains and analyzes the operational data.The experimental results show that the system is stable in operation and high in accuracy,which can meet the design requirements and has positive significance for ensuring the safety of highway tunnel operation.
