摘　　要：针对森林火险预测预报及林火扑救辅助指挥设计了一套森林消防车车载微环境实时监测系统,该系统可实现对消防车周边风速风向、空气温度、空气湿度、CO_2浓度、CO浓度、烟雾浓度、大气压力等微环境参数及地理信息的实时监测,采用北斗卫星通信技术可实现林区微环境信息的无死角传输。基于STM32微处理器的森林消防车微环境实时监测系统集成了多种高性能检测传感器,采用两级降压结构,保证了系统工作的稳定可靠。使用两对互相垂直安装的风速风向传感器,并用车速信息和车辆三维姿态信息进行校正,实现了消防车任意行驶状态下对水平风速风向的实时测量。数据传输采用北斗风GYT2015C数传终端,可满足系统所处林区环境的通信要求。Aim at forecasting of forest fire danger and auxiliary command of forest fire suppression,we designed a system fixed on a forest fire engine to collect the real-time environment information around the fire engine.It realize the real time monitoring and transmission of wind speed,wind direction,air temperature,air humidity,C0 2 concentration,CO concentration,smoke concentration and atmospheric pressure around the fire engine and the geographic location information by BeiDou Navigation Satellite System.Based on STM32 micro controller u n it,th is system combine a series of high-performance sensors.Two stage voltage dropping structure ensures the stability and reliability of the system.Wind speed and direction are measured by two pair of vertically fixed sensors,and are corrected by vehicle speed and 3D attitude.It realized the real-time measuring of horizontal wind speed and direction in any situations.GYT2015C module is used to satisfied the demand of communication.
