摘　　要：为了消防官兵第一时间掌握火灾现场毒气种类和浓度,做出正确的消防措施,将有毒气体进行二进制编码,并建立了有毒气体距离与时间的扩散模型,提出了有毒气体浓度解析算法,设计了基于单片机+Lab VIEW的北斗导航模拟侦检训练系统,实现了消防人员在有毒环境中的模拟训练与考核。经测试,该系统可正确判断毒气种类,气体浓度测试值与理论值误差较小。结果表明系统通信可靠,运行稳定,具有安全环保,经济高效的优点。In order to help the firefighters to grasp the fire site type and concentration of the fire in the first time to adopt the correct fire measures,we make the toxic gas binary code and establish the distance and time diffusion model of toxic gas.Furthermore,we put forward the toxic gas concentration analysis algorithm and design the Microcontroller-based BeiDou navigation of simulation detection and training system with Labview to achieve the goal of simulation training and assessment for the firefighters in the toxic environment.After testing,the system could correctly determine the type of gas,and the error of gas concentration test value and the theoretical value is small.The results show that the system is reliable and stable,and has the advantages of safety,environmental protection and economy.
