摘　　要：设计4路2L大体积NaI(Tl)γ能谱仪提高对地探测灵敏度,使用GPS秒脉冲同步获取谱线数据,谱线数据经TCP/IP传输到空中机载工控机中和其他信息打包,并使用LZMA减小打包数据的体积,打包数据和HDMI图像经数传图传一体机发送到地面接收端解码,实现谱线显示和核素分析,整个传输过程中保证了时间的精度和远距离传输的实时性。本实时数据传输方法可广泛应用于无人机辐射测量场合,可解决辐射测量数据实时传输的问题。Design a 4-way 2L large-volume NaI(Tl)gamma spectrometer to improve the sensitivity of ground detection.The GPS second pulse is used to acquire the spectral line data synchronously.The spectral line data is transmitted to the airborne industrial computer and other information package via TCP/IP.And use LZMA to reduce the volume of the packed data.The packed data and the HDMI image are sent to the ground receiving end for decoding by the digital transmission and transmission machine to realize the spectral line display and the radionuclide analysis,and the time precision and long distance are ensured during the whole transmission process.The real-time data transmission method can be widely applied to the drone radiation measurement occasion,and can solve the problem of real-time transmission of the radiation measurement data.
