嵌入式雪崩灾害无人监测预警系统的设计

Design of Unmanned Monitoring and Early Warning System Based on Embedded Avalanche Hazard

设计一种以S3C2440为平台的无人实时监测雪崩发生的系统,该系统以32位低功耗、高性能的ARM9处理器为核心,以uC/OS-II操作系统为软件平台,采用TG-3DP型号三轴低频加速度传感器采集数据。通过ARM内部的A/D模数转换后,系统处理与标准值作报警值判断,通过Zigbee模块将发生的雪崩报警状态值传送给山下路旁的LED大灯显示,配合GPRS模块将数据以短信形式远程发送到数据控制中心显示。系统采用稳定的太阳能和蓄电池联合供电系统,使其具有体积小、可靠性高、操作简便等优点,适用于降雪量大、无人看管的地区灾害监测。

Describing a S3C2440＇s system of unmanned platform for real-time monitoring Avalanche constitute,the system is built based on a 32-bit low-power.High-performance ARM9 processor is taken as the core,and the uC / OS-Ⅱ operating system as the software platform.The TG-3DP model triaxial low-frequency acceleration sensor collects data and makes the system processing for alarm value judgment by A/D analog-to-digital conversion of the inside of ARM.It will work through the Zigbee module by sentting the avalanche of alarm status value to the foot of the mountain side of the road LED headlamps with GPRS module which is finished by the form of text messages remotely senting to the data control center at the same time.The steady solar energy and battery power serve the system.The proposed system has advantages of small size,high reliability,easy operation,etc,which is applied to large amount of snowfall unattended regional disaster monitoring.
