In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model;

As shown in Figure 1: present embodiment mainly is made up of cryptochannel and controlled circuit, and cryptochannel is at least by three controllable silicon SCR ₁, SCR ₂, SCR ₃(present embodiment is three) and a plurality of release knob K ₁-K ₁₀(present embodiment is ten) constitutes, controllable silicon SCR ₁, SCR ₂, SCR ₃Be connected in series successively, wherein SCR ₁Negative electrode pass through K ₄-K ₁₀The power connection negative pole, SCR ₂Negative electrode meet SCR ₁Anode, SCR ₃Negative electrode meet SCR ₂Anode, K ₁-K ₃Pass through resistance R ₃Positive potential be connected on SCR respectively ₁-SCR ₃The control utmost point; Controlled circuit by and be connected in SCR ₃Anode and the relay between positive source constitute that (present embodiment is two J ₁, J ₂), relay J ₁, J ₂The contact respectively circuit and the oil circuit of controlling machine motor-car, relay J ₁, J ₂The contact multiple connection mode is arranged, (as shown in Figure 2) its connection mode, relay J for Control of Automobile platinum igniting ₁Armature contact be connected on the cell negative terminal of platinum point fire coil primary winding, open contact is connected on the binding post of current distributor platinum, normally closed contact is connected on the positive pole of power supply by the demagnetization diode, the setting of demagnetization diode is in order to improve theftproof performance.(as shown in Figure 3) it is the connection mode of control ignition coil: relay J ₁The positive potential of armature contact contact give a signal, open contact is connected on Ignition Module and triggers on the input line, normally closed contact is by diode ground connection.(as shown in Figure 4) it is the connection mode of control oil channel electromagnetic valve (oil pump), relay J ₂Armature contact contact fire switch, open contact connects the positive pole of oil circuit solenoid electric valve, the negative earth of oil circuit solenoid electric valve (connection mode of electronics oil pump is the same).(as shown in Figure 5) it is the connection mode of Control of Automobile, motorcycle electric high-tension coil, relay J ₂Armature contact connect on the electronic ignition coil primary winding output wiring terminal, open contact be connected on Ignition Module (high-tension coil) control input wiring terminal.The working process of present embodiment is as follows: open the self-propelled vehicle ignition lock, when pressing K ₁The time, power supply passes through resistance R ₃Make the SCR control utmost point add forward voltage, SCR ₁Conducting, SCR ₁After the conducting, SCR ₂Negative electrode through SCR ₁Plus earth, the forward voltage of power supply is added to SCR ₂Anode and negative electrode between perform conducting and prepare.When pressing K ₂The time, power supply also passes through resistance R ₃Make controllable silicon SCR ₂The control utmost point add forward voltage, SCR ₂Conducting, in like manner, controllable silicon SCR ₃Also perform conducting and prepare, when pressing K ₃The time, just can make controllable silicon SCR ₃Conducting is connected on SCR ₃Relay J on the anode ₁, J ₂Action, coded lock is opened.Button K ₄-K ₁₀For destroying key, in the process of unblanking, only need press any one key in these seven keys, just make controllable silicon SCR ₁Cathode return circuit cut off, thereby end controllable silicon SCR ₂, SCR ₃Also end accordingly.Open ignition lock, start coded lock, relay J ₁Action, power supply passes through the primary winding of high-tension coil to relay J from positive pole ₁Armature contact, connect platinum through open contact again and constitute the loop.Coded lock quits work, relay contact disconnects, connect the diode of normally closed contact, the thief is as high-tension coil and platinum direct connection, during starting, power supply passes through high-tension coil---connection lead---platinum constitutes the loop, in platinum open circuited moment, the electromagnetic induction that high-tension coil produces is got back to high-tension coil formation demagnetization loop by the diode and the positive pole of relay armature contact, normally closed contact, so the secondary generation of high-tension coil does not go out high-tension current.In the Ignition Module circuit, open ignition lock, start coded lock, relay J ₁Action, Starting motor.The positive potential signal that signal generator in the Ignition Module produces is connected Ignition Module by relay armature contact, normally closed contact, makes Ignition Module work.Electronic password lock quits work, relay J ₁Armature contact disconnect, connect normally closed contact, Ignition Module quits work because of can not get energizing signal.Promptly use lead directly trigger winding to be connected with Ignition Module, Ignition Module can not worked yet, because the demagnetization diode that the forward potential that energizing signal produces is connected on the normally closed contact mourned to release, so fail to start.Second relay J ₂Control method simple, can oneself select, open ignition lock, start coded lock, relay J ₁And J ₂Be parallel running, at this moment, power supply is by elementary, the relay J of high-tension coil ₂Armature contact, open contact, Ignition Module constitutes the loop, Ignition Module work, when password quits work, relay J ₂Open contact disconnect, high-tension coil can not get the control of Ignition Module and quits work.Open ignition lock, start coded lock, relay J ₂Action, power supply is from ignition lock---relay J ₂Armature contact---open contact is connected the positive pole of oil passage control valve, and the negative earth by oil passage control valve constitutes the loop again, oil circuit is connected in oil passage control valve work.Electronics oil pump control principle is the same, and when coded lock quits work, oil passage control valve can not get the voltage that open contact comes and interrupts oil circuit, quits work.
