A control circuit of a flying toy that can return automatically

Abstract

The invention discloses a flying toy control circuit allowing automatic toy return. The circuit comprises a decoding unit, an MCU microprocessor, a driving unit, a motor, an antenna, a storage and a detection circuit. The antenna is used for receiving and transmitting wireless signals. The decoding unit is used for removing carriers in the wireless signals to obtain originally modulated digital signals, namely the signal intensity information. The MCU microprocessor processes digital output and instant signal intensity information of the decoding unit to decide whether to transmit driving signals to the driving unit, the driving unit converts the signals into voltage or current required by the motor after receiving the driving signals, the motor acts according to the regulation under control of the voltage or current information of the driving unit, and the detection circuit is used for converting detected liquid level information or ground information into digital signals and transmit the digital signals to the MCU microprocessor. The flying toy control circuit enables a flying toy to return safely when the flying toy lands on unsatisfactory sites like roofs and water surface.

Description

technical field [0001] The invention relates to a control circuit of an airplane toy, in particular to a control circuit of a flying toy capable of automatic return. Background technique [0002] At present, the control circuit of flying toys on the market mainly includes decoding unit, MCU, drive unit, motor and antenna, and generally only receives commands from the remote control in one direction. To prevent the aircraft from exceeding the remote control range of the remote control, it is necessary to keep pressing the remote control button To send continuous command codes, when the flying toy does not receive the command, it will stop supplying power to the main control motor, and the flying toy will land by itself. Because there is no power, the flying toy will generally hit the ground heavily, which is easy to damage, and the flying toy is far away from the remote control When the controller is far away, the flying toy may receive incomplete data, mistakenly think that ...

To prevent the aircraft from exceeding the remote control range of the remote control, it is necessary to keep pressing the remote control button To send continuous command codes, when the flying toy does not receive the command, it will stop supplying power to the main control motor, and the flying toy will land by itself. Because there is no power, the flying toy will generally hit the ground heavily, which is easy to damage, and the flying toy is far away from the remote control When the controller is far away, the flying toy may receive incomplete data, and may mistakenly think that there is no command and land by mistake. At this time, it may land on an unfavorable location such as a roof or water surface, causing failure to receive commands or damage
