Signal collection and transmission apparatus of self-changing gearbox

The invention discloses an automatic gearbox signal acquisition and transmission device, comprising a signal acquisition module connected with each sensor in the automatic gearbox, a signal processing module and a communication module used for transmitting the acquired signal to a user. The signal processing module comprises a single chip; the input terminal of the signal acquisition module is connected with each sensor of the automatic gearbox; the output terminal thereof is connected with the single chip; the communication module is a radio communication module and comprises a radio transmitting terminal and a radio receiving terminal; the radio transmitting terminal is connected with an interface of the single chip; and the radio receiving terminal is connected with the interface of the user. The acquired related signal in the gearbox processed by the single chip is transmitted to the user in the radio communication manner, so as to eliminate false connection caused by a very complex signal wire harness.
