The setting of camera is to shoot one in landforms or the execution task where current unmanned plane
Divide, especially earthquake disaster area or conflagration area etc..The main function of ground control system controls system to the flight of unmanned plane
System is controlled, more accurate in order to position, and outer in ground control system can add antenna.
Therefore compared to existing six wings unmanned plane for, the especially setting of horn 1, the embodiment of the present invention provide
Unmanned plane using modularized design, all parts are separately formed, so having broken away from and the integrally formed mould structure of housing
Limitation, not only reduces cost, and easy to carry.
Second aspect, Fig. 4 are the control method schematic diagram that makes a return voyage that the first is applied to above-mentioned multi-rotor unmanned aerial vehicle, are applied to
Flight control system, this method include：
S101 in the case where not receiving remote controller signal and ground control system signal, starts LED light, and
Calculate the time for not receiving remote controller signal and ground control system signal；
Wherein, LED light is out of touch simultaneously for display remote controller and earth station.
S102 is more than the situation of preset time in the time for not receiving remote controller signal and ground control system signal
Under, whether the judging currently to set of the task is completed；If not completing, S103 is performed, if completion, performs S104；
Wherein, preset time can be 5S.
S103 continues the tasks carrying according to setting, until the task of setting is completed, a little makes a return voyage according to making a return voyage for record；
In this step in unfinished setting task, it is still to after continuing to complete setting task, can just makes a return voyage, to have ensured
Into the purpose of this flight.
It should be noted that making a return voyage for record herein a little can be understood as unmanned plane and fly to current location record according to rising
Path coordinate.
S104 a little makes a return voyage according to making a return voyage for record.
From the foregoing, it will be observed that the first control method of making a return voyage provided in an embodiment of the present invention is not by receiving remote controller signal
