Two, remove anti-theft state.Press K5 to K9, MCR2 to MCR6 triggering and conducting successively in proper order by predetermined ignition code, J2 switch on the open contact J2-2 closure of adhesive, J2, provide path for C4.The normally closed contact J2-1 of J2 disconnects, the J1 outage discharges, produces four course of action: 1. the open contact J1-2 of J1 disconnects.2. the contact J1-1 of the J1 negative pole that recovers positive ground, the C4 of normally-open normally-close state, C4 produces a negative going pulse, J5 and triggers the closing of contact of transformation condition, J5, gets ready for the conducting of J6 because of negative going pulse.3. the normally closed contact J1-4 closure of J1, ignition lock (12) ［ K12 ］ and firing unit (14) are connected.4. the normally closed contact J1-3 closure of J1, ignition lock (12) ［ K12 ］ and starter (11) ［ M ］ are connected.Close according to a conventional method this moment ignition lock (12) ［ K12 ］, MCR7 triggering and conducting, J6 energising adhesive, the contact conversion of J6, the power end of high-tension coil (15) ［ B ］ is converted to the power connection positive pole by ground connection, and firing unit (14) enters normal working and produces the igniting high pressure.Anti-theft state removes the back, by battery-conserving switch button (8) ［ K11 ］, J2 outage release, reduced electric energy because of the long-term conduction loss of J2, the normally closed contact J2-1 closure of J2, get ready for start anti-theft state next time.

Three, starting anti-theft state.Course of action power end the same, high-tension coil (15) ［ B ］ when entering anti-theft state by the anti-beneficial shift knob (6) ［ K10 ］ of starting, MCR1 triggering and conducting and energising is converted to ground connection, ignition lock (12) ［ K12 ］ and firing unit (14), all is cut off with the path of starter (11) ［ M ］, the utility model enters anti-theft state.

Four, defencive function.

1, ignition code protection.Non-owner by arbitrary button (5) among the K0 to K4, T1, T2 conducting, J4 energising adhesive, produce two course of action: 1., the normally closed contact J4-1 of the J4 path, the ignition code that disconnect, cut off fully J2 lost efficacy.2., the open contact J4-2 closure of J4, IC work, T3, T4 conducting, loudspeaker (10) ［ Y ］ sound the alarm.Rationally select C1, R12 for use, just can guarantee that J4 continues the conducting adhesive within a certain period of time.This moment if in order by ignition code shift knob K5 to K9, J2 still can not conducting, firing unit (14) still can't produce the igniting high pressure.

2, ignition code is protected in proper order.Not according to the anode of first button K5 of predetermined ignition code button ［ K5 to K9 ］, not conducting of MCR2, MCR3 do not have voltage, can triggering and conducting by second button K6, MCR3 of ignition code button ［ K5 to K9 ］ yet, in like manner as can be known, must press that shift knob (5), ignition code are just effective, J2 ability conducting adhesive by predetermined ignition code in proper order, anti-theft state could be removed.

3, strong destruction protection.After primary controller suffers strong destruction or cuts off the electricity supply, J1, J2 cut off the power supply, its open contact J1-2, J2-2 disconnect, the positive pole of C4 can not ground connection, and the negative pole of C4 can not produce that path that negative going pulse, J5 can not trigger transformation condition, J6 continues to disconnect, the normally closed contact of J6 makes the power end of high-tension coil (15) ［ B ］ still keep ground connection.Ignition lock (12) ［ K12 ］, starter (1) ［ M ］ and firing unit (14) close this moment though but can still can't produce the igniting high pressure by energized positive pole firing unit (14).

4, external connection short circuit or open circuit protection.With ignition lock (12) ［ K12 ］, storage battery (13) ［ E ］, starter (11) ［ M ］, the any short circuit of external connection of primary controller (1) and firing unit (14) or when opening circuit, all can not make the J5 two ends produce negative pulse voltage (during as the external connection ［ C ］ that will trigger the J5 conversion and ground short circuit, the J5 both end voltage is 0, during with the positive source short circuit, the J5 both end voltage is a power line voltage, with other each line short circuit or when opening circuit, the voltage at J5 two ends is 0 or is power line voltage), J5 can not trigger transformation condition, the path of J6 continues to disconnect, the normally closed contact of J6 makes the power end of high-tension coil (15) ［ B ］ still connect the pond, when power line voltage was shorted to firing unit (14), firing unit still can't produce the igniting high pressure.

5, power-off protection.Behind the power cut-off, the course of action when J1 outage discharges and protects with strong destruction is the same, J5 do not have negative pulse voltage can not transformation condition, the normally closed contact of J6 makes the power end of high-tension coil (15) ［ B ］ still keep ground connection.The same, the utility model of course of action during energized, when C2 makes J3 conducting adhesive in short-term enter anti-theft state with energising still keeps anti-theft state again.

6, plunder protection.When the firing unit normal operation produces the igniting high pressure (automobile in motion), suffer that the ruffian plunders, owner's flicking starts anti-theft state button (6) ［ k10 ］ once, the MCR1 triggering and conducting is the same with the course of action of starting during anti-theft state, the firing unit cisco unity malfunction, can't produce igniting high pressure, (automotive engine auto shut down), the utility model enters anti-theft state.

1., reasonable in design, simple in structure, easy to use, burglary insurance, cost is lower, applicability is strong main feature of the present utility model is:. 2., have the protection of enciphered ignition, error code, strong destruction protection, external connection short circuit or the functions such as open circuit protection, power-off protection and rob-proof protection, and the password combination number is more, application value is bigger.
