closed, due to first via control circuit anode electricity The normally opened contact end of source input terminal and the second relay J2 are connected by conducting wire, so, first via control circuit can obtain electric this moment Work.When thering is passenger or driver to open right car door, after radio transmitter U2 launches the second road wireless signal, this moment, wirelessly Receiving circuit U3 can receive the second road wireless signal, and then, second 3 foot of high level output end of wireless receiving circuit U3 is defeated Go out high level, through the 5th resistance R5 decompression current limlitings into the 4th NPN triode Q4 base stages, the 4th NPN triode Q4 is led high level Logical collector output low level is into the 4th relay J4 negative power supply input terminals, and then, the 4th relay J4, which is obtained, electric is attracted it Power input and normally opened contact end is controlled to be closed, due to the second tunnel control circuit cathode power supply input terminal and the 4th relay The normally opened contact end of J4 is connected by conducting wire, so, the second tunnel control circuit can obtain electric work this moment.In first control circuit： NAND gate I in second digital integrated electronic circuit U4（1 foot, 2 feet, 3 feet）With NAND gate II（5 feet, 6 feet, 4 feet）Composition monostable is touched Power Generation Road, after first control circuit obtains electric work, 1 foot of NAND gate I datum input terminal of single-shot trigger circuit due to ground connection, this It carves, single-shot trigger circuit overturning enters temporary stable state, under the 3rd electrolytic capacitor C3, the 6th resistance R6 collective effects, NAND gate II 4 foot of output terminal sports low level, and low level signal is through NAND gate III（8 feet, 9 feet, 10 feet）After reverse phase, in the 4th electrolysis Under capacitance C4 collective effects, the 10 feet output high level of NAND gate III is into the 4th resistance R4 one end, subsequently into the 3rd NPN tri- Pole pipe Q3 base stages, the 3rd NPN triode Q3 conducting collector output low levels enter the 3rd relay J3 negative power supply input terminals, Then, the 3rd relay J3 obtains its control power input of electric actuation and normally opened contact end is closed；After spending about 10 seconds, monostable Trigger circuit is returned to stable state, and 10 feet of NAND gate III no longer export high level, and then, the 3rd relay J3 dead electricity stops inhaling It closes；Due to, the 3rd relay J3 normally opened contacts end of first via control circuit cathode power supply output terminal and first via LED display Diode VD2 (diode VD2 has 0.8V or so voltage drops, meets LED display utilization voltage needs) anode is connected by conducting wire It connects, so this moment, the 3rd relay J3 is obtained in 10 seconds of electric actuation, more light-emitting diodes of first via LED display Pipe LEDN can obtain electroluminescence, after more Light-emitting diode LED N of first via LED display shine, show " opening left-hand door " ', with This simultaneously, after the 3rd relay J3 obtains electric actuation, loud speaker B, which can be obtained, electric sends loud sound and more Light-emitting diode LED N hair " opening left-hand door " ' of light composition prompts front vehicle front vehicles to open left-hand door together, so as to which front vehicle driver subtracts Speed is braked in order to avoid causing the accident.In second control circuit：NAND gate I in second digital integrated electronic circuit U4（1 foot, 2 feet, 3 Foot）With NAND gate II（5 feet, 6 feet, 4 feet）Single-shot trigger circuit is formed, after second control circuit obtains electric work, monostable is touched 1 foot of NAND gate I datum input terminal of Power Generation Road is due to ground connection, and this moment, single-shot trigger circuit overturning enters temporary stable state, the 3rd Under electrolytic capacitor C3, the 6th resistance R6 collective effects, 4 foot of output terminal of NAND gate II sports low level, low level signal warp NAND gate III（8 feet, 9 feet, 10 feet）After reverse phase, under the 4th electrolytic capacitor C4 collective effects, the 10 feet output of NAND gate III is high Level enters the 4th resistance R4 one end, subsequently into the 3rd NPN triode Q3 base stages, the 3rd NPN triode Q3 conducting collectors Low level is exported into the 3rd relay J3 negative power supply input terminals, then, the 3rd relay J3 obtains electric actuation, and its controls power supply Input terminal and normally opened contact end are closed；After spending about 10 seconds, single-shot trigger circuit is returned to stable state, 10 feet of NAND gate III High level is no longer exported, then, the 3rd relay J3 dead electricity stops being attracted；Due to the second tunnel control circuit cathode power supply output The 3rd relay J3 normally opened contacts end is held to be connected with the diode VD2 anodes of the second paths of LEDs display screen by conducting wire, so this It carves, the 3rd relay J3 obtained in 10 seconds of electric actuation, and more Light-emitting diode LED N of the second paths of LEDs display screen obtain electric Shine, after the second more of paths of LEDs display screen Light-emitting diode LED N shines, show " opening right car door " ', at the same time, the 3rd After relay J3 obtains electric actuation, loud speaker B1, which can be obtained, electric sends loud sound and more Light-emitting diode LED N shine composition " opening right car door " ' prompts front vehicle front vehicles to open right car door together, so as to which front vehicle driver is slowed down or is braked In order to avoid it causes the accident.

In the utility model actual use, first via control circuit and the second tunnel control circuit can share a loud speaker B, the Connect a diode VD3-1 between the relay J3-1 normally opened contacts end of control circuit and the loud speaker B other ends all the way, the Connect a diode VD3-2 between the relay J3-2 normally opened contacts end of two tunnel control circuits and the loud speaker B other ends, and second The VD3-2 cathode of road control circuit and the diode VD3-1 cathode of first control circuit link together, in so working, the After the relay J3-1 of one control circuit obtains its control power input of electric actuation and normally opened contact end closure, second source G2 is just Pole can control power input and normally opened contact end, diode VD3-1 anodes and cathode through relay J3-1, through diode VD3- 1 one-way conduction enters the loud speaker B other ends, and then loud speaker B obtains electric work sounding, due to the diode of second control circuit VD3-2 cathode are connected with VD3-1 cathode, after the relay J3-1 of first control circuit obtains electric actuation, because second control circuit Diode VD3-2 be in reverse blocking state, so, first control circuit relay 3-1 normally opened contacts end output power supply Anode will not enter the second paths of LEDs display screen, prevent from impacting the second paths of LEDs display screen normal work；In work, second After the relay J3-2 of control circuit obtains its control power input of electric actuation and normally opened contact end closure, second source G2 anodes Power input and normally opened contact end, diode VD3-2 anodes and cathode can be controlled through relay J3-2, through diode VD3-2 One-way conduction enters the loud speaker B other ends, and then loud speaker B obtains electric work sounding, due to the diode of first control circuit VD3-1 cathode are connected with the diode VD3-2 cathode of second control circuit, and the relay J3-2 of second control circuit obtains electric actuation Afterwards, because the diode VD3-1 of first control circuit is in reverse blocking state, second control circuit relay J3-2 The positive pole of normally opened contact end output will not enter first via LED display, prevent from working normally first via LED display It impacts.Front vehicle is hit on open car door when the utility model can effectively prevent vehicle door opening, has accomplished intelligent control System reduces therefore causes human casualty accident, based on the above, so the application prospect that the utility model has had.
