Vehicle-mounted drunk-driving-prevention electronic control system

Technical Field

The utility model relates to an automobile safety technical field, concretely relates to utilize alcohol test sensor to realize motorist's safe driving's electronic control module.

Background

At present, drunk driving is still a main inducing factor of road traffic accidents, and some automobile drivers still drive drunk after putting national laws and people's lives and properties to go. Aiming at drunk driving, a plurality of laws and regulations are issued by the country, the punishment on drunk driving is increased, but some people are willing to leave something to be lucky, so that drunk driving is prohibited frequently, traffic accidents are frequent, great hidden dangers are brought to traffic, and great losses are caused to the life and property of the country and people. For drunk driving, although law enforcement checks of traffic police departments and penalty constraints of laws and regulations exist, the drunk driving can be passively executed only after drunk driving, and no technical preventive measures and means before drunk driving exist at present.

The alcohol detector is used for detecting whether a human body takes alcohol and the alcohol intake degree. The device can be used as a detection tool for detecting the drinking amount of a drinker when the traffic police enforces the law, so that the occurrence of serious traffic accidents is effectively reduced. However, a common user rarely has an alcohol detector, the alcohol content in the body can be reduced to the degree of driving permission after trace drinking and long drinking, and the individual can hardly judge the alcohol content without the alcohol detector, so that inconvenience is brought to the traveling of many drivers.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: a vehicle-mounted drunk driving prevention electronic control system is provided.

The technical solution of the utility model is that: the vehicle-mounted drunk-driving-prevention electronic control system comprises an alcohol detection device, a signal transmitting unit, a signal receiving unit and an electronic control module, wherein the electronic control module is used for controlling the starting of a vehicle, the alcohol detection device is connected with the signal transmitting unit and used for transmitting an alcohol detection signal, the electronic control module is connected with the signal receiving unit and used for receiving the alcohol detection signal transmitted by the signal transmitting unit, when the alcohol detection device detects the existence of alcohol gas, the signal is transmitted to the signal receiving unit through the signal transmitting unit, and a vehicle starting circuit is cut off through the electronic control module.

The technical effects of the utility model are that: it has that structural design is reasonable, installation and convenient to use's advantage, and this module cooperation alcohol testing arrangement has the function that automated inspection wine drove, once detects that the driver drunk, will cut off the power supply to a plurality of systems of car, makes the car normally start to avoid the emergence that wine drove. Meanwhile, for drivers who drink a little wine and have a rest for a long time after drinking, the driver can actively detect the driver through the product so as to prevent and avoid unnecessary drunk driving behaviors and bring convenience to the driver.

Detailed Description

As shown in fig. 1, 2 and 3, the vehicle-mounted drunk-driving prevention electronic control system comprises an alcohol detection device, a signal transmitting unit, a signal receiving unit and an electronic control module, wherein the electronic control module is used for controlling the starting of an automobile, the alcohol detection device is connected with the signal transmitting unit and used for transmitting an alcohol detection signal, the electronic control module is connected with the signal receiving unit and used for receiving the alcohol detection signal transmitted by the signal transmitting unit, when the alcohol detection device detects the existence of alcohol gas, after signal acquisition and processing, the signal is transmitted to the signal receiving unit through the signal transmitting unit, and an automobile starting circuit is cut off through the electronic control module.

The electronic control module comprises a relay J1, a relay J2, a time relay SJ and a control relay KJ, wherein the relay J1 is provided with a trigger end which is connected with an infrared alcohol test recognition device through a signal acquisition processing circuit, the input end of the relay J1 is connected with the positive electrode and the negative electrode of a power supply, the output end of the relay J1 outputs positive and negative voltages, the relay J2 is provided with a coil and a normally closed switch, the time relay SJ is provided with a trigger end and a normally closed switch, the control relay KJ is provided with a trigger end and a plurality of normally open switches, the coil of the relay J2 is connected with the output end of the relay J1, the positive electrode of the output end of the relay J1 is connected with one end of the normally closed switch of the relay J2 through a diode D1, a resistor R1 and a voltage stabilizing diode D2, the connecting end of the resistor R1 and the voltage stabilizing diode D2 is connected with the negative electrode of the output end of the relay J1 through, the normally closed switch other end of relay J2 still triggers the end with time relay SJ and is connected, and time relay SJ's normally closed switch one end is connected with the anodal of relay J1 output, and the other end is connected with control relay KJ's trigger end, and control relay KJ's normally open switch is used for controlling the start of car.

The alcohol detection device may slide along a safety belt.

And the trigger end of the time relay SJ is also connected with a decoder for unlocking the time relay SJ in advance.

The decoder is connected through the interface, and the function of unlocking a plurality of sets of systems can be realized.

And a normally open switch of the control relay KJ is respectively connected in series in a power supply circuit of the fuel pump, the automobile central computer, the ignition switch and the starter. And meanwhile, multiple points are controlled, so that drunk driving is completely avoided.

The alcohol detection device is installed and fixed on a safety belt of a driving seat.

The alcohol detection device may slide along a safety belt.

The system does not work without starting the car. When the alcohol concentration is detected to be zero by a sensor of the alcohol detection device, J1 is closed, and a normally closed point is opened by electrifying and attracting J2. When the alcohol concentration exceeds the standard, the J1 is powered off, the J2 is powered off and closed, the capacitor C2 high potential triggers the delay relay SJ to be powered off in a delay mode, the delay relay is opened in a normally closed mode, and a control circuit power supply is disconnected, so that the fuel pump, the automobile central computer, the ignition switch and the starter cannot work in an electrified mode. After 6 hours (the time can be set according to actual needs), the SJ starts to be closed and connected, and the next working state is recovered.
