Problems solved by technology
The transmission control is the working mode of continuous transmission by pressing the transmission control key; the remote control signal transmission is to transmit the digital address and data signal modulation carrier, and the amplitude modulation mode is the most commonly used. This kind of remote control signal transmission exists under the same carrier modulation. When the remote controllers are used within the remote control range at the same time, the problem of out of control is often caused by mutual interference between the same frequency, especially in the control application of remote control electric vehicles, because the steering is a jog control method of continuous code transmission, using this In this way, the radio remote control system may be in the working state of emitting interference or in the working state of being interfered, so that the remote control electric vehicle will lose control and produce various adverse consequences

Description
Technical field: [0001] The invention relates to a radio remote control system, in particular to a multifunctional radio remote control module for resisting same-frequency interference for remote control electric vehicles. Background technique: [0002] The existing civil radio remote control system consists of two parts: transmitting and receiving. The transmitting part is composed of coding IC, transmitting module, transmitting antenna, control buttons, power supply (battery) and shell; the receiving part is composed of receiving module, decoding IC or software Composition of decoding and control circuit. There are two types of coding methods for commonly used emission coding ICs: fixed code and rolling code. The transmission control is the working mode of continuous transmission by pressing the transmission control key; the remote control signal transmission is to transmit the digital address and data signal modulation carrier, and the amplitude modulation mode is the mo...
