Refer to accompanying drawing 1, the structural representation of a kind of vehicle anti-theft circuit disclosed in the embodiment of the present invention. The embodiment of the invention discloses a kind of vehicle anti-theft circuit, concrete structure comprises: be connected with power cathode, has two coded order receptors 101 that can set arbitrarily acceptor's module device of coding; Be connected with coded order receptor 101, the coded order that coded order receptor 101 is sent identify without the time difference pair code instruction identify circuit 102; Being connected with without the time difference two code instruction identify circuit 102, during the Throttle Opening Control circuit instruction send and open car door lock, connected car, control car enters the normal execution path 10 3 starting shape body of awaiting orders, and performs path 10 3 and is connected with positive source; It is connected with coded order receptor 101 communication, the coded order set in advance by sending to coded order receptor 101, control car enters to await orders and starts traveling state, has two and can set arbitrarily the hand-held without the time difference two code instruction transmitter 104 of coded order transmitter; The circuit 105 of automatically deploying troops on garrison duty being connected with power cathode, positive pole and coded order identify circuit respectively.
Above-mentioned coded order receptor is have acceptor's module device that two can set arbitrarily coding, and it act as receipts and turns instruction. After receiving the hand-held instruction sent without the time difference two code instruction transmitter, immediately this instruction is transmitted to two yards of instruction identify circuits.
Vehicle anti-theft circuit provided by the present invention eliminates the link implementing to report to the police by vibration transducer mode, adopt without the time difference two code instruction control and the multiple control measure that this pair of code instruction is identified, all only implement car door lock the basis of control adds the control to car throttle circuit at existing most burglar alarm simultaneously, allow and steal car thief and both do not opened car door, even if robber car thief forces open the door also cannot start, drive away the vehicle in parking, guarantee reliably antitheft, the invention also discloses a kind of antitheft device with above-mentioned vehicle anti-theft circuit, solve existing anti-theft device of motor vehicle password to be easily decrypted, the problems such as false wrong report, that fundamentally guarantees vehicle parks safety.
Refer to accompanying drawing 2, the principle of work circuit diagram of a kind of vehicle anti-theft circuit disclosed in the embodiment of the present invention.
Described above comprise without the time difference two code instruction identify circuit: single-phase silicon-controlled Q2, single-phase silicon-controlled Q3, switching tube Q4, switching tube Q5, switching tube Q6, switching tube Q7 and peripheral R3-R13 resistance circuit, described single-phase silicon-controlled Q2 is connected with the anode of diode D2 with described diode D1 respectively with the control end of described single-phase silicon-controlled Q3, the emtting electrode of described switching tube Q4 is connected with the collector electrode of described switching tube Q5, the base stage of described switching tube Q4 is connected through the negative electrode of described R9 with described single-phase silicon-controlled Q3, the base stage of described switching tube Q5 is connected through the negative electrode of R10 with described single-phase silicon-controlled Q2.
Wherein, described switching tube Q1, switching tube Q4, switching tube Q5, switching tube Q6 and switching tube Q7 are NPN triode.
Execution passage described above comprises: switching tube Q8, switching tube Q9, relay J 1, relay J 2 and peripheral R14-R15 resistance circuit, wherein, described relay J 1 and described relay J 2 are dynamic circuit connector type rly., and described switching tube Q8 is connected with the coil of described relay J 1 with described relay J 2 respectively with the collector electrode of described switching tube Q9.
Wherein, described switching tube Q8 and described switching tube Q9 is NPN triode.
Automatically the electric routing switch pipe Q0 that deploys troops on garrison duty described above, switching tube Q1, electric capacity C and K switch and resistance R0-R2 etc. form, it act as: when car owner is after car, switch " K " is opened a way, electric capacity starts charging, through the about 60-90 second, the instantaneous conducting of Q0 makes Q1 conducting, and Q2, Q3 is blocked by diode D1, D2, by withdrawing a garrison, working order automatically switches to working order of deploying troops on garrison duty to antitheft device, it is ensured that vehicle park safety.
Wherein, being reached switching tube Q0 is double-basis diode, and K switch is for by logical press button.
Above-mentioned it is made up of (wherein Q2, Q3 are one-way SCR) Q2, Q3, Q4, Q5 etc. without the time difference two code instruction identify circuit. It act as the coded order to coded order receptor is sent to and identifies, when the instruction received is code instruction two without the time difference, and the instruction send to the execution passage being made up of Q8, Q9, J1, J2 immediately and open car door lock, connected car throttle circuit.
Demoder can only scan the high-end of this frc decoder vehicle theft-proof device or low side coding, and no matter demoder scans from high-end to low side, or from low side to high-end scanning, the Q7 in circuit is by by Q6 transmission of stop instruction by the power supply cut-out of coded order receptor. Therefore, demoder cannot change the antitheft working order of this frc decoder vehicle theft-proof device at all, thus reaches reliably antitheft object.
Above-mentioned execution passage by, Q8, Q9, J1, J2 etc. form, its task is: when receive coded order identify circuit send open car door lock, connect car Throttle Opening Control circuit instruction time, J1 open immediately car door lock, J2 connect car Throttle Opening Control circuit. Car is made to enter normal activation state of awaiting orders.
Above-mentioned hand-held have, without the time difference two code instruction transmitter, the transmitter that two can set arbitrarily coded order, by sending the coded order set in advance to coded order receptor, it is achieved antitheft device is by the conversion of working order of deploying troops on garrison duty to working order of withdrawing a garrison. Car is made to enter to await orders and start traveling state, corresponding without the time difference pair code command receiver with described above.
On the basis of above-mentioned disclosed a kind of vehicle anti-theft circuit, the invention also discloses a kind of antitheft device, comprise above-mentioned disclosed vehicle anti-theft circuit.
In sum: the present invention discloses a kind of vehicle anti-theft circuit, this vehicle anti-theft circuit eliminates the link implementing to report to the police by vibration transducer mode, and also abandoned the sense of hearing that antitheft device realizes sending when state changes, visual information, adopt without the time difference two code instruction control and the multiple control measure that this pair of code instruction is identified, when making the conversion of antitheft working order and non-antitheft working order, all do not send any sense of hearing, visual information, only implement car door lock the basis of control adds the control to car throttle circuit at existing burglar alarm simultaneously, allow and steal car thief and both do not opened car door, also cannot start, drive away the vehicle in parking, guarantee reliably antitheft, the invention also discloses a kind of antitheft device with above-mentioned vehicle anti-theft circuit, solve existing anti-theft device of motor vehicle easily decoded, the problems such as false wrong report, fundamentally guarantee vehicle safety.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are enable to realize or use the present invention. To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.
