Unmanned helicopter flying signal conversion device and unmanned helicopter

The invention discloses an unmanned helicopter flying signal conversion device and an unmanned helicopter. The unmanned helicopter flying signal conversion device comprises an engine control switch signal conversion module, a total distance signal conversion module and an alarm signal conversion module. The total distance signal conversion module is used for calculating and converting a total distance signal provided by a flight control system computer and a voltage signal provided by an engine electronic controller to obtain a converted total distance signal output to the engine electronic controller; the engine control switch signal conversion module is used for connecting a parking input/flight input/ground slow input signal of the electronic controller with a common output end in the electronic controller according to engine control switch signals such as a parking signal, a ground slow signal and a flight signal provided by the flight control computer; enabling the engine electronic controller to output
