Abstract

The invention discloses a model airplane remote control system, belonging to the field of remote control equipment. The model airplane remote control system mainly comprises a crystal oscillator, a high-frequency circuit, a transmitting antenna, a power supply, a control lever, a variable potentiometer, an encoder, a switch circuit, a frequency selection circuit, a receiving antenna, a steering engine, a decoding circuit, and an amplifying circuit, and is characterized in that the control lever is connected with the variable potentiometer, the variable potentiometer is connected with a signalgenerator and the encoder, a signal generated by the encoder passes the switch circuit and then is carried on the high-frequency circuit, the crystal oscillator generates oscillation frequency, and finally, the transmitting antenna sends out the signal. The receiving antenna is connected with the frequency selection circuit, the frequency selection circuit is connected with the crystal oscillatorand the amplifying circuit, the frequency selection circuit selects and transmits a matched signal to the amplifying circuit, the amplifying circuit is connected with the decoding circuit, the signalis amplified and then is converted by the decoding circuit, and the decoding circuit is connected with the steering engine.

Description

technical field [0001] The invention relates to an aircraft model remote control system, which belongs to the field of remote control equipment. Background technique [0002] The model airplane remote control system includes a model airplane transmitter and a model airplane receiver. The transmitter is used to control the car model or ship model. Because it has a long transmitting antenna outside, the remote control commands are all through the control switches and buttons outside the casing. The modulation and coding of the internal circuit, and then the electromagnetic wave is emitted by the transmitting antenna through the high-frequency signal amplification circuit. The remote control receiver is installed on the model car or ship to receive radio signals. It will process the radio signal from the remote control transmitter, amplify, shape and decode the received signal, and convert the received control signal into an audio signal or a digital pulse signal that the exec...
