森林消防车无网络通信定位及参数采集系统设计

为了实现在无信号林区对森林消防车的定位及参数采集，采用传感技术、北斗短报文技术，研发了一种基于北斗短报文的通信定位及参数采集系统，该系统包括数据采集系统、北斗短报文通信系统。参数采集系统采用STM32 芯片采集传感器数据，同时利用三防平板电脑的GPS 定位功能获取森林消防车的位置，在原始林区弱信号甚至是无信号情况下利用北斗短报文技术上报消防车的传感器参数和位置信息，指挥车车载终端收到报文信息，在本地存储并上传到云端，支持APP 实时显示。经测试，系统定位的精度可克服环境空旷程度的影响，整体运行情况良好，符合林区无网环境下消防车参数和位置信息采集需求，能够作为提高无信号林区救援的有效手段，从而提高无信号林区消防救援的安全性和高效性。

Fire engine communication,positioning and parameter acquisition system design for forest area without network

 In order to realize the positioning and parameter acquisition of forest fire engines in less net forest areas, a communication positioning and parameter acquisition system based on Beidou short message is developed by using sensing technology and Beidou short message technology. The system includes data acquisition system and Beidou short message communication system. The designed parameter acquisition system uses STM32 chip to collect sensor data, and uses the GPS positioning function of the tablet computer to obtain the position of the forest fire truck. Under the condition of weak signal or even no signal in the original forest area, Beidou short message technology is used to report the sensor parameters and position information of the rescue fire truck. The vehicle terminal of the command vehicle receives message information, stores it locally, uploads it to the cloud, and supports APP real- time display. The test results show that the system positioning accuracy can overcome the influence of environmental emptiness,and the whole system runs well and can collect the parameters and position information of the fire truck in the non- network environment, which meets the expected design requirements and can be used as an effective means to improve the rescue of the non- signal forest area, so as to improve the safety and efficiency of the fire fighting in the non-signal forest area.
