The accompanying drawing explanation

Fig. 1 is the inside theory diagram of the automotive diagnostic installation of the present invention with Bluetooth amplifying function;

Fig. 2 is the vehicle diagnosis method process flow diagram that the present invention has the Bluetooth amplifying function.

Embodiment

In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.

Refer to shown in Figure 1ly, Fig. 1 is system principle diagram of the present invention.The present invention is to provide a kind of automotive diagnostic installation with Bluetooth amplifying function, it is mainly used in solving auto repair work personnel when auto repair, because of environment is noisy and both hands with oil stain (machine oil etc.), and cause the problem of sending a telegram here and can't answer.

The automotive diagnostic installation that the present invention has the Bluetooth amplifying function mainly includes diagnostic module, MCU, power protection and modular converter, Bluetooth adapter, sound out-put circuit, Speech input circuit, loudspeaker, earphone, microphone, key-press module and pilot lamp.

Wherein diagnostic module, MCU and Bluetooth adapter are connected with power protection and modular converter respectively, power by power protection and modular converter.Power protection and modular converter mainly are comprised of power protecting circuit, DC/DC change-over circuit, for each functional module of equipment provides required direct supply.Diagnostic module is for realizing normal automobile measuring ability.

Bluetooth adapter is connected with MCU, for set up with outside communication terminal (mobile phone) between Bluetooth pairing be connected, it includes the modules such as Bluetooth antenna, is mainly used in realizing the bluetooth connection, is paired into the physical support that this equipment provides wireless connections; Described sound out-put circuit, Speech input circuit, key-press module and pilot lamp are connected with described MCU respectively, and loudspeaker is connected with sound out-put circuit respectively with earphone, are the voice output terminal; Microphone is connected with described Speech input circuit, is the Speech input terminal; Described key-press module is connected with described MCU with pilot lamp, be used to realizing the input of button, mainly includes volume up/down, answers the buttons such as (redialing/Bluetooth pairing) and on-hook (rejection).

Wherein the Speech input circuit is comprised of A/D change-over circuit etc., be used to realizing the input processing of sound; Sound out-put circuit is comprised of D/A change-over circuit, loudspeaker and earphone selection circuit etc., processes be used to the output that realizes sound.Pilot lamp is mainly used in the indication when the front module working condition, if during when red, means that Power supply is normal; Blinking red lamp 3 times, representation module initialization running is normal; The green light flicker, mean in Bluetooth pairing; Green light Chang Liang, mean Bluetooth pairing and successful connection; Red/green light is flicker alternately, means that bluetooth does not connect etc.

Specific works principle of the present invention is as follows: when equipment was powered, corresponding pilot lamp can show that red light lights, module initialization afterwards, blinking red lamp 3 times; After length is pressed " answering " key 5s, open the Bluetooth pairing function, now pilot lamp green light flicker, green light Chang Liang during successful matching, if button does not match, acquiescence is used the last time pair record to connect, do not carry out the bluetooth connection traffic lights alternately flicker point out; When incoming call is arranged, press " answering " key, telephone receiving, can converse; During conversation, press the on-hook key, conversation is hung up; During incoming call, press on-hook key 2s, hear after " ticking " sound to be refusing incoming call; While not conversing, connect and press " answering " key 2 times, namely again dial one and dial the number; Press " volume increases "/" volume down " key, can realize increase and the minimizing of volume.

Shown in Figure 2, the present invention also provides a kind of vehicle diagnosis method with Bluetooth amplifying function, comprising:

S1, automotive diagnostic installation by Bluetooth adapter set up with outside communication terminal between Bluetooth pairing be connected;
