Fig. 3 is a kind of support software schematic flow sheet of the present utility model.According to this figure, the professional is not difficult to work out out program, but the establishment of specific procedure varies with each individual, so do not list.

Principle of work of the present utility model is roughly as follows:

(1) microcomputer is under software is supported, when the input of reading the alarm button switch, hidden warning, then is in due course according to vehicle-state and sends the alerting signal that the occupant can not find by relay control and signal sending circuit; When openly reporting to the police, then send strong sound and light alarm signal by relay control.

(2) microcomputer reads the received adjacent car signal of signal receiving circuit under software is supported, the alarm message of adjacent car is shown on light-emitting diode display.

(3) microcomputer is under software is supported, by reading overtake other vehicles button switch and the received adjacent car signal of signal receiving circuit, control the transmission of request signal and answer signal of overtaking other vehicles of this car, and the attitude of this car and the attitude of adjacent car show on light-emitting diode display will overtake other vehicles the time.

(4) during hidden warning, microcomputer by relay control, makes vehicle that short time " simulated failure " take place randomly under software is supported, to delay road speed, is convenient to arrest the ruffian, the rescue driver.

Mend again below and chat alleged hidden warning and the open notion of reporting to the police of the utility model.

Hidden warning: hidden warning is by ultrasound transmitter device and the additional lamp after being installed on car is realized.After entering hidden warning, the super sonic transtation mission circuit constantly sends the ultrasonic signal of " this car is held as a hostage " or " this car is stolen " forward and backward, if in the vehicular traffic same protector is housed, promptly can receives and tells this car driver with the form of acousto-optic.Simultaneously, additional lamp at high speed glittering (or combination light on and off of certain rule) send the rescue alarm signal of " this car is dangerous " to pedestrian, traffic police.Because of ultrasonic signal people ear is imperceptible; Wigwag only just sends at driving states, and dead ship condition does not have, so the people is also imperceptible in the light warning signal car, has only the pedestrian to find, is called hidden warning so plant type of alarm.This kind type of alarm is applied in when stealing car and robbing car the ruffian and does not do harm to driver or driver as yet in the powerless occasion that is not easy to open warning.

The open warning: the open warning realized by horn trumpet, light, additional lamp, buzzer phone.When driver's life be subjected to danger or and when robbing car ruffian blog fight, the switch that can push for emergency this moment carries out open warning.When openly reporting to the police, firing circuit cuts off, and vehicle can not start, and simultaneously, sound light alarming circuit is connected, and acousto-optic volleys, and realizes the purpose of open warning to pedestrian and the emergency of other vehicle with this.
