Problems solved by technology

The detection results of alcohol testers sold on the market are quite accurate. For example, the HH2 type police alcohol detector produced by Australia Aikelisi Technology (Alcolizer Technology) company has a good effect, but it must be detected when the law enforcement officers catch the drunk driver. Therefore, such products cannot universally solve the problem of drinking and driving

Embodiment Construction

[0010] exist figure 1 Among them, terminals c and d are respectively connected to the positive pole and negative pole of the car battery, and R4 and VD3 form a simple voltage stabilizing circuit and directly supply power to the system.

[0011] A in this circuit is a special sensor for alcohol gas detection, which requires fast response, good stability, long life, low power consumption, little influence of temperature and humidity, and a minimum detection range of less than 10ppm. For example, the TP-3C normal temperature alcohol sensor developed by Shenzhen Daweilai Sensing Technology Development Co., Ltd. is more suitable. To ensure reliability, multiple sensors can be connected in parallel.

[0012] In the best solution of the present invention, the alcohol sensor adopts detachable installation, that is, a special plug-in is welded at the corresponding position of the circuit board, and the sensor is directly connected with the plug-in, which is convenient for the replaceme...

Abstract

The system comprise a alcohol sensor, a voice generating circuit, a speaker, a relay, a vibrating switch, a fan, a resistor, capacitors, diodes, voltage stabilizing triode, triodes, and potentiometer. The resistor R4 and voltage-stabilizing diode VD3 composes a simple stabilizing circuit used for providing power for system; after the alcohol sensor detects the alcohol gas, it triggers the voice generating system to generate voice to warn the car driver not to drive the car and meanwhile triggers the automatically powering off unit to break off the firing circuit of the car.

Description

Technical field [0001] The invention relates to an intelligent control system capable of automatically disconnecting an automobile ignition circuit. technical background [0002] As we all know, frequent drunk driving accidents have become the biggest killer of traffic. Although relevant departments have stepped up management efforts, it is difficult to see results. The detection results of alcohol testers sold on the market are quite accurate. For example, the HH2 type police alcohol detector produced by Australia Aikelisi Technology (Alcolizer Technology) company has a good effect, but it must be detected when the law enforcement officers catch the drunk driver. Therefore, such products cannot universally solve the problem of drunk driving. And the intelligent control system that the present invention relates to can disconnect ignition circuit automatically under the situation that detects the alcohol in the air, plays voice warning at the same time, fundamentally prevent...
