By amplifier IC6B is the main one-level adder that constitutes, with after the voltage addition of the voltage of E8 and W7 sliding end by the 7 pin output of amplifier, R76 and W7 are that the quiescent voltage of IC6B is adjusted the loop, can make the mouth of amplifier that a fixed voltage be arranged when the static state by regulating W7, support the dead band voltage of the emitter-base diode of cutting aerotron N8, R79 and R80 are the isolation resistance of adder two-way input end, and R81 and R77 are the backfeed loop of amplifier.The d. c. voltage signal of the 7 pin output of IC6B is sent into the base stage of aerotron N8-N12 respectively through R69-R73, number difference by institute's bonded assembly diode on the emitter of each aerotron, the desired base tension of conducting also is not quite similar, can judge the distance of leading vehicle distance, signal was also very weak when current spacing was far, the neither conducting of aerotron N8-N12, make light-emitting diode L29-L33 not luminous, when leading vehicle distance is nearer, signal a little less than, make aerotron N8 conducting, light-emitting diode L29 is also lighted thereupon, along with leading vehicle distance is more and more nearer, signal is more and more stronger, aerotron N9 and N10 and N11 also are switched on successively, light-emitting diode L30 and L31 and L32 are lighted successively, when leading vehicle distance very near, signal is the strongest, make aerotron N12 conducting, light-emitting diode L33 is lighted, R69-R73 is respectively the base stage current-limiting resistance of each aerotron, R64-R68 is respectively the current-limiting resistance of each light-emitting diode, D14 improves the dead band voltage of aerotron N9 and the diode that inserts, D16 and D20 improve the dead band voltage of aerotron N10 and the diode that inserts, D19 and D21 and D17 improve the dead band voltage of aerotron N11 and the diode that inserts, the dead band voltage of D23 and D22 and D18 and D15 raising aerotron N12 and the diode that inserts.Flash of light and auditory tone cues, under normal circumstances, NAND gate circuit IC11 input end is high level, mouth is a low level, by the signal of the 2H2 of LM555 time base circuit IC12 generation being blocked with door IC2B, make the voltage of the emitter output of aerotron N13 be always zero, by the oscillation frequency of R84 and R85 and E11 decision IC12,3 pin of IC12 are the oscillator signal mouth; When the distance of the overtake other vehicles signal or the front and back car of the turn sign of front truck or back car is very near, a low level will appear in the IC11 input end, the mouth that makes IC11 is a high level, thereby open IC12 produces the 2H2 signal, the emitter voltage that makes aerotron N13 was with cycle saltus step between the zero-sum power line voltage of 0.5 second, make buzzer phone C32 send the sound of interruption and accordingly by the light-emitting diode of this place power supply also glimmering, send the acousto-optic warning signal.Localpower is taken from storage battery on the car, is introduced by J25 and J26, supplies with entire circuit after the V1 voltage stabilizing, wherein 1 pin of J25 and J26 is anodal, and E10 and C31 are output filter capacitor, and V1 is an integrated voltage stabilizer, 1 pin is the positive source input end, and 2 pin are the shared grounding end, and 3 pin are output end of pressure-stabilizing.VCC in the circuit is a positive source,

Being power cathode, is to link together separately on circuit.
