The invention discloses a fixed-wing unmanned aerial vehicle time domain aviation electromagnetic exploration system. A transmitting system, a receiving system and a recording and monitoring system are additionally arranged on an unmanned aerial vehicle flight platform. The transmitting system comprises a transmitter and a transmitting coil, and the transmitter is installed in the load cabin and used for converting direct current into bipolar combined wave pulse current; the transmitting coil is installed on the unmanned aerial vehicle nose, the unmanned aerial vehicle wings and the unmanned aerial vehicle pelvic fin structure in a closed shape and used for generating a primary electromagnetic field for measurement of the aviation electromagnetic system; the receiving system comprises a receiver nacelle and an electric winch, and the receiver nacelle is installed below the belly of the unmanned aerial vehicle through a receiver nacelle hanging frame and an automatic throwing device, islocated under the load cabin and is used for receiving a secondary electromagnetic field generated by induced eddy current from an underground conductor; the electric winch is mounted below the bellyof the unmanned aerial vehicle through an automatic throwing device, is positioned right ahead the receiver pod and is used for synchronous winding and unwinding and overload shearing of a three-component receiving coil in the receiver pod; and the recording monitoring system is arranged in the load cabin and is used for recording, storing and receiving the data acquired by the receiving system.

    一种固定翼无人机时间域航空电磁勘查系统,在无人机飞行平台上增加发射系统、接收系统和收录监控系统。发射系统包含发射机和发射线圈,发射机安装在载荷舱内,用于将直流转换为双极性组合波脉冲电流;发射线圈以封闭形状安装在无人机机头、无人机机翼和无人机腹鳍结构上,用于产生航空电磁系统测量用的一次电磁场;接收系统包括接收机吊舱和电动绞车,接收机吊舱通过接收机吊舱挂架、自动投放装置安装在无人机机腹下方且位置处于载荷舱的正下方,用于接收来自地下导体中感应涡流产生的二次电磁场;电动绞车通过自动投放装置安装在无人机机腹下方且位置处于接收机吊舱的正前方,用于接收机吊舱内部三分量接收线圈的同步收放及过载剪断;收录监控系统安装在载荷舱内,用于记录存储接收系统所采集的数据。
