In order to be illustrated more clearly in the purpose of this utility model, feature and advantage, describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.

In the accompanying drawing:

Fig. 1 is the circuit diagram of traditional motorcycle alarm.

Fig. 2 is a circuit diagram of the present utility model.

Fig. 3 is transmitter circuit figure of the present utility model.

Fig. 4 is a shock detection circuit diagram of the present utility model.

Please consult Fig. 2 earlier, the utility model includes acceptor circuit 1, amplifying circuit 2, decoding circuit 3, logical process and controls parts such as circuit 4, output driving circuit 5, its cooperation remote-control signal transmitter 6 as shown in Figure 3, and the shock detection circuit 7 that is installed on the motor bike as shown in Figure 4 can have functions such as remote control starts, pressure is flame-out, indicator glimmers, vibrations are antitheft, squelch anti-stealing, anti-theft switch.

Remote-control signal transmitter 6 is by an IC(for example 2262) and subsidiary component constituted, be transfused in this IC by four function key control commands, modulate the series type signal through its coding, launch via transmission circuit again.Because its structure belongs to prior art, so do not giving unnecessary details at this.

Shock detection circuit 7 is installed on the motor bike, it includes elements such as amplifier OP2, OP3 and close-up crystal unit 71, when being shaken, close-up crystal unit 71 can change its voltage, and this signal amplifies its amplitude through OP2, be sent to OP3, and when amplitude reached the comparative voltage that sets above OP3, the mouth of OP3 will be increased to high potential by active potential, to form a positive pulse signal, transport to logical process control circuit 4 again.

After radio receiver circuit 1 receives and transmits, receive by transistor Q1, restore modulation signal to eliminate carrier signal, signal after the demodulation amplifies its amplitude through the transistor Q2 of amplifying circuit 2, through op amp OP1 wave shaping is become digital signal again, so that decoding circuit 3(wherein demoder for example is 2272) these signal decodings are reduced into the state that four function keys are awaited orders, that is the antitheft setting of D3 (output signal ON), the antitheft releasing of D2 (output signal OFF), D1 squelch anti-stealing (output signal MUTE), the DO remote control starts (output signal START), and when pushing each function button, the VT output of this decoding circuit 3 will remain on high potential always, till decontroling button.

After the antitheft setting of pressing function key D3, when shock detection circuit 7 is touched, the binary pair F1(of logical process control circuit 4 for example 4013) the end (pin 8) that presets be set at height, mouth (pin 13) then is high, make transistor Q3 action through a resistance, promote relay R Y2 action through the reverser I2 of output driving circuit 5 again, reach and force flame-out purpose, this signal promotes the RY1 action through reverser I4 simultaneously, make twice of indicator flicker, and, siren horn SP is piped through parasite I6 transistor Q4 conducting promotion siren horn, it is antitheft to reach warning, frighten the purpose of resistance.When the resistance of F1 mouth, electric capacity through charging to high potential, then Car Burglar Alarm is replied the state of alert.When the thief opens the tapered end of motorcycle handle with master key, the output of motor bike tapered end will change 12V output into, this moment is if under antitheft setting, then the end (pin 8) that presets of F1 is set at high potential, pin 13 output positive voltages, through transistor Q3, reverser I2 promotes relay R Y2 and does flame-out action, and the thief can't be started smoothly, and promote transistor Q4 alarming horm SP is cried, to reach the theft-proof purpose of warning.
