Description of drawings: Fig. 1 is to be the square frame principle synoptic diagram of the utility model control circuit; Fig. 2 is that the structural principle master of the utility model backguy transducer looks synoptic diagram; The structural principle schematic top plan view of Fig. 3 the utility model seat controller.25-base fixing threaded hole.

Embodiment: it is made of control circuit, backguy transducer 9 and seat controller 10 3 parts.Control circuit comprises PIN PAD 1, Hall element 2, gas sensor 3, door contact interrupter 4, A type telepilot 5, Type B telepilot 6, program module 7, execution module 8, power supply 11, input end in program module 7 is connected with input unit 1, Hall element 2, gas sensor 3, program module 7 has three tunnel outputs, output J1 provide enabling signal for car door lock, output J4 provide signal for acousto-optic electric alarm system, the written-out program signal is to execution module 8, execution module 8 outputs four road signals, output J2 can start the car signal for firing circuit provides, output J3 is the flash of light alarm signal, output to backguy transducer 9, output to seat controller 10; PIN PAD 1, Hall element 2, gas sensor 3, execution module 8, backguy transducer 9, seat controller 10 common port after the end parallel connection of totally six parts with after an end of door contact interrupter 4 is connected, connect the positive pole of power supply 11, the other end of PIN PAD 1, Hall element 2, gas sensor 3, execution module 8, backguy transducer 9, seat controller 10 constitutes the closed-loop path by the negative pole of earthing mode and power supply 11 respectively.One end of program module 7 connects the positive pole of power supply 11, and the other end constitutes the closed-loop path by the mode of ground connection and the negative pole of power supply 11; The power supply of A type telepilot 5, Type B telepilot 6 is provided by the dry cell that carries, and self constitutes the closed-loop path.Backguy transducer 9 is made up of spring 12, moving plate fixing spring 13, electromagnet latch 14, stator pilot hole 15, stator 16, moving plate 17, connecting hole 18, electromagnet 19, moving plate locking 20, stator fixing spring post 21, moving plate 17 is arranged on stator 16, electromagnet 19 is arranged below stator 16, spring 12 1 ends are connected with stator fixing spring post 21 on the stator 16, the other end is connected with moving plate fixing spring 13 on the moving plate 17, electromagnet 19 below electromagnet latch 14 and the stator 16 is connected, and is fixedlyed connected with the car body cover lock through connecting hole 18 by screw.Seat controller 10 is made up of seat controller loam cake 22, the moving core 23 of electromagnet, base 24, solenoid 26, has electromagnet to move core 23, solenoid 26 on seat controller loam cake 22 times, base 24.The utility model course of work: signal output part J1 provides enabling signal for car door lock, and J2 can start the car signal for firing circuit provides, and J4 provides signal for acousto-optic electric alarm system, and J3 is the flash of light alarm signal.The source of all signals all is that program module is looked operator instruction and provided.

Telepilot has two kinds of signal emission functions: the one, and specific electric wave signal can make the program module received signal and open car door lock; The 2nd, infrared ray transmitting function.Can make the PIN PAD received signal and (send instruction, make it make corresponding action for program module.A type telepilot does not possess the alcohol detection function, can directly certainly send instruction for the program mould by PIN PAD, makes execution module offer corresponding J1-J4 or backguy transducer and seat controller by its instruction and carries out signal, makes its action.The Type B telepilot then has the alcohol detection function, must could send instruction to program module through the approval of PIN PAD.By making its rotation with the moving Hall element of air-blowing, gas sensor begins to detect and testing result is delivered to PIN PAD simultaneously, confirms whether drink.As by confirming, can make program module obtain instruction, and provide instruction to execution module, make corresponding J1-J4 or backguy transducer and seat controller carry out signal, make its action.Otherwise in the time of can not passing through to confirm because of drinking, PIN PAD can be sent caution sound and remind the driver not drive, and closes start-up circuit simultaneously, and vehicle can't be started.When the car stealer wants to cross the direct short circuit automobile igniting circuit robber of alarm car, because backguy transducer, seat controller are normally opens when not having instruction, therefore the car stealer not stretchy lacing wire line machine cover is opened, also just can't the short circuit firing circuit, consequently can't steal car.The backguy transducer is become by stator, moving plate, electromagnet and electromagnet insert group, and machine cover length is changed.Implementation procedure is as follows: when electromagnet obtained the instruction of execution module, the electromagnet latch ejected, and stator and moving plate are fixed.This moment, moving plate shortened, and can spur machine cover and open; Otherwise when electromagnet can not get the instruction of execution module, the electromagnet latch can not eject, and stator and moving plate can't be fixed, and this moment, moving plate was elongated, and machine cover can't be opened.The seat controller is to be made of base, the moving core of electromagnet, solenoid and seat controller loam cake.Principle be with the seat controller with screw below the base fixing threaded hole is fixed on automotive seat, when closing seat, the moving core of electromagnet ejects under the solenoid effect, and seat is fixed, and makes the car stealer can't contact automotive ignition system, car can't be stolen.After the moving core of electromagnet was received the instruction of execution module, the solenoid action sucked back, and removed seat and fixed, and can open seat this moment, so that overhaul machine.Another major function of backguy transducer is to completely abolish the lacing wire line, the backguy transducer is fixed on machine cover locks face, can reach directly actuated purpose.The utility model can give not that the alcohol user drives to bring convenience, and drink and can not drive also can for driver from drunk driving person caution, has effectively reduced the danger of driving when intoxicated and being brought.Coded lock also provides safety guarantee for automobile burglar.
