The invention belongs to the technical field of electrical communication, and particularly relates to missile-borne image transmission external field test equipment which comprises a multi-rotor unmanned aerial vehicle, a remote controller, a SBus radio station transmitting end, a SBus radio station receiving end, a double-shaft PWM steering engine holder and a tested image transmission antenna. The advantages and disadvantages of the existing technical scheme are used for reference: by combining the characteristic of simple instruction operation of a remote controller and the characteristic of relatively stable flight of a multi-rotor unmanned aerial vehicle, a SBus wireless data unvarnished transmission device is added, so that the remote control communication distance of hundreds of meters of a common remote controller is increased to dozens of kilometers or even hundreds of kilometers; meanwhile, a double-shaft PWM steering engine holder device is carried on the multi-rotor unmanned aerial vehicle, pitching and yawing instructions generated by a rocker of a remote controller are responded, the rotation angle of the image transmission antenna in the flight process of the multi-rotor unmanned aerial vehicle is conveniently controlled, the communication performance of the image transmission antenna with the ground under the condition of different rotation angles is tested, operation is easy, running is stable and reliable, and the test efficiency is high. And the method has universality.
本发明属于电气通讯技术领域,具体涉及一种弹载图传外场测试设备,所述设备包括:多旋翼无人机、遥控器、Sbus电台发射端、Sbus电台接收端、双轴PWM舵机云台和被测图传天线;其借鉴了现有技术方案的优点缺点:通过结合遥控器指令操作简单的特点和多旋翼无人机飞行比较平稳等特点,增加Sbus无线数据透传装置,将普通遥控器几百米的遥控通讯距离增加至几十公里甚至上百公里,同时在多旋翼无人机上搭载了双轴PWM舵机云台装置,响应遥控器的摇杆产生的俯仰和偏航指令,方便控制多旋翼飞机在飞行过程中图传天线的旋转角度,实现测试图传天线不同转角情况下与地面的通讯性能,操作简单、运行稳定可靠,具有普适性。
