乘员舱危险元监控及主动预警系统设计

Design of Danger Element Monitoring and Active Early Warning System for Passenger Cabin

针对保障乘员舱内气体安全的问题,文章分析了多种情况下车内环境主要的不安全因素,利用单片机、传感器、GPRS模块和有源蜂鸣器等装置,设计了集监控、主动预警于一体的智能系统。本系统通过对车内气体浓度和温度进行实时监控并利用GSM网络,将危险信息通过短信发送给用户,实现了检测准确化、反馈智能化和预警及时有效化。

Aiming at the problem of ensuring the safety of the gas in the passenger compartment,the main unsafe factors of the environment in the vehicle under various circumstances are analyzed.Using a single-chip computer,a sensor,a GPRS module,an active buzzer and other devices,an intelligent system integrating monitoring and active warning is designed.The gas concentration and temperature in the car are monitored by the system in real time,and the danger information is sent to the user via SMS via the GSM network,so that the accurate detection,intelligent feedback,and effective early warning can be achieved.
