[0002] The hybrid vertical take-off and landing unmanned aerial vehicle has two attitudes of vertical flight and horizontal flight, each of which needs independent flight control for control, and the two different flight controls (fixed wing and multi-rotor) need to be connected through a remote controller and switched in the appropriate flight stage.
[0003] Conventional flight control connection reference Figure 1 The signal transmission of the whole line is single, only one set of flight control system is needed, and expansion and cross are not needed. However, if one more set of flight control is added, two problems are involved: 1. the receiver signal needs to be expanded into two groups and transmitted to two flight controls respectively, and the channels used will be different; 2. the two flight controls need to control the same group of rudders in different working conditions, and there will be a problem of control authority allocation. If the rudders receive signals from two flight controls at the same time, an error will occur, so only one flight control can send control instructions to the rudders in the same stage.
[0004] Generally speaking, for the case of hybrid control flight control, two groups of development boards need to be specially developed and made, which are respectively placed between the receiver and the flight control, and between the flight control and the rudders. The former is used to select the receiver signal to transmit to the flight control, and the latter is used to select the flight control signal to transmit to the rudders. However, different aircrafts use different types of flight controls, which need to be developed and tested separately, which is time-consuming and costly. A general solution is needed.

[0018] Beneficial effects:
[0019] The present application flexibly uses the training module on the judgment and output of the flight control signal, reduces the cost of the separately developed switching module; the connection has no requirement on the brand, function and the like of the receiver, the flight control and the rudder, and different brands and different functions of the flight control can be selected to be mixed together; 3. The connection can also be used in the backup mode and other working modes of the flight control; when the conventional flight control is powered on and started, the ground must be kept stationary to perform the calibration work. The connection mode can ensure that the start of two flight controls is completed on the ground at the same time, the two flight controls receive the control instructions and make the control judgment in the sky at the same time, only the training module decides whether to output, so that the problem of unsuccessful switching of the flight control in the air can be solved.
