| The Airborne gamma spectrometer is an important aviation geophysical equipment, which is widely used in mineral exploration, environmental radioactive contamination evaluation, and other aspects of nuclear emergency. Aviation gamma spectrometer for unattended automatic monitoring, not only in improving aviation gamma spectrometer automation level has an important role, but also has practical significance in aviation safety radiometric production. Currently field production process, there must be members of flight operations on the airplane for airborne gamma spectrometer operation, the field production Task wide area, complicated geographical conditions, the presence of members of personal aircraft operator safety problems. For the above, this project was designed and implemented an airborne gamma spectroscopy unmanned automatic monitoring system (referred to as: unmanned systems), the system can be remotely controlled airborne airborne gamma spectrometer on the ground, real-time access and lower fat mass spectrometer status information when an exception occurs spectrometer, a key recovery so remote troubleshooting. The system can improve aviation gamma spectrometer productivity, ensure safety, security aerogeophysical equipment, efficient, high-quality production escort.At present, domestic and international research in the field of aerogeophysical unattended system is mainly used aeromagnetic systems, avionics systems, in view of its limited carrying drones, in aviation gamma spectrometer (Airborne Radiometric system) is only equipped 1-2 4LNaI (TI) UAV Airborne Radiometric system crystals, such aeroradiometric system is only used for environmental radioactivity measurements. Existing domestic and international aviation gamma spectrometer is mainly used for mineral exploration, we need 10 4L NaI (TI) crystal or more. In this thesis, we completed the UAV can be applied to both environmental radioactivity measurements and airborne radioactive geophysical exploration occasions unmanned systems.By unmanned airborne gamma spectroscopy system of research and development, the main research results are as follows:1, the design is complete the unmanned airborne gamma spectroscopy system contains airborne unattended monitoring subsystem, the ground control center subsystem and space, including one remote communications subsystem; to achieve a long-range airborne gamma spectrometer unmanned, mass spectrometer status information in real-time monitoring and remote fault a key recovery features.2, completed the airborne gamma energy spectrum of quality of information transmission reliable data communication link Beidou satellite-based, airborne terminal Beidou satellite to airborne automatic monitoring host collected to the ground control center, ground staff can view real-time on the ground Air quality status information and gamma ray spectrometry system to send commands to reset a key aviation gamma spectrometer;3, the design is completed airborne master unattended monitoring software, aviation and energy spectrum monitoring software and ground control center software, and asynchronous manner the TCP pipeline between the monitoring host and EDS host/IP sockets communications, energy dispersive spectrometer measurements host inter-process software and monitoring software for asynchronous master named pipe communication, and by agreement designed to achieve a stable and reliable coordination between the synchronous operation of multiple subsystems;4, the design is complete RS232 hardware alarm 2 sets to achieve the airborne side airborne surveillance and alarm IPC communication, and in accordance with ground command command for remote alarm, alarm return, hardware reset and other operations.5, the index of the system was tested in AGRS finished interior debugging and testing, the Changchun Airport and Shijiazhuang large guocun airport completed dynamic flight testing, July 28,2014 to September 2 In Jilin rock performed 15 sorties day trial, the test result is good, the instrument is stable and performance to meet aviation requirements for spectral measurement unattended.By unmanned airborne subsystem and subsystem hardware and software design ground control center, to achieve the air-ground integrated remote wireless communications, is completed based on airborne gamma spectroscopy Beidou satellite communications system unattended. Design unmanned airborne gamma spectroscopy spectrum systems, more sorties by field testing and production results of Beijing, Chang chun, Shijia zhuang and other places show that the ability to remotely start measuring, real-time mass spectrometer to obtain status information, and can When an exception occurs spectrometer, a key remote recovery, reach the desired design goals. |
