Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1 to 3, in an embodiment of the present invention, an integrated intelligent drunk driving prevention system includes a single chip microcomputer and an alcohol sensor mechanism connected to the single chip microcomputer, the alcohol sensor mechanism includes a main alcohol sensor and an auxiliary alcohol sensor electrically connected to an alcohol concentration detector, wherein the main alcohol sensor includes a first main alcohol sensor and a second main alcohol sensor, the first main alcohol sensor is installed at a position corresponding to a top end of a vehicle door in a main cab, the second main alcohol sensor is installed directly above a driver seat, the auxiliary alcohol sensor includes a first auxiliary alcohol sensor and a second auxiliary alcohol sensor corresponding to the first main alcohol sensor, the first auxiliary alcohol sensor is outwardly fanned with the first main alcohol sensor as a center, the second auxiliary alcohol sensor is installed at a center position of a steering wheel, in this embodiment, an operation space in a vehicle with a side length of 1500 is taken as an example, the number of the first auxiliary alcohol sensor and the second auxiliary alcohol sensor is seven and one respectively, the specific vehicle type and the number of the alcohol sensors can be changed and converted according to specific conditions, the type of the alcohol sensors is a fuel cell type, the main alcohol sensor and the auxiliary alcohol sensors can send detected alcohol information to the alcohol concentration detector, the information comprises the time when the alcohol is detected and the number information of the sensors, the single chip microcomputer in the embodiment further controls and is connected with an alarm mechanism, and preferably, the alarm mechanism is at least one of a voice alarm and an alarm flashing light.

In practical application, the first main alcohol sensor and the second main alcohol sensor can output measured information to the alcohol concentration detector, the detection result of the alcohol concentration detector is output to the single chip microcomputer, whether alcohol exists in the vehicle or not is preliminarily judged, whether drunk driving conditions exist or not is judged, then if the drunk driving conditions exist in the current vehicle are judged, the auxiliary alcohol sensors start to detect, the time of alcohol gas reaching each fixed position is different according to the principle that alcohol diffuses in the air and has a certain flow speed, the source of the alcohol is accurately judged by recording the time of alcohol detected by each auxiliary alcohol sensor, misjudgment and misoperation that the vehicle cannot be normally started and used due to the fact that a non-driver drinks are avoided, after the accurate judgment result is generated, if the driver is confirmed to have drunk driving conditions, the single chip microcomputer controls the alarm mechanism to alarm, the alarm mode can be acousto-optic alarm.

Example 2

Please refer to fig. 1, in an embodiment of the present invention, an integrated intelligent drunk driving prevention system further includes a pressure sensor connected to a single motor, and preferably, the pressure sensor is a film type contact sensor, the number of the pressure sensors is two, and the two pressure sensors are respectively installed at the bottom of a carpet in front of a main driver seat and the driver seat, the pressure sensor below the main driver seat is used for determining whether a person is in the driver seat, the pressure sensor at the bottom of the carpet in front of the driver seat is used for determining whether a person is in the driving operation range, and meanwhile, if the person who drives with wine wants to change another person to start the engine and then drives himself, the signal of the pressure sensor disappears, and at this time, the single chip can receive the signal and send out the signal, thereby showing the anti-fraud capability of the system.

Example 3

Please refer to fig. 1, in the embodiment of the utility model provides an in, a synthesize intelligent system of driving of preventing drinking, because when in practical application, the door window is opened the back, can have the influence of wind-force, consequently, increased in this embodiment with the miniature wind speed determinator of singlechip electric connection, can measure the wind speed, it can give the singlechip with wind speed information transmission to the singlechip, so that the singlechip is when the alcohol information of receiving main alcohol sensor and vice alcohol sensor gained, revise information such as the receipt time of alcohol information, in order to guarantee measuring accuracy.

Example 4

Please refer to fig. 1-2, in the embodiment of the present invention, the single chip microcomputer is connected with the vehicle controller through the CAN control bus, which CAN acquire the start/stop information of the vehicle from the vehicle controller, and also CAN send the instruction to the vehicle controller, so that the vehicle controller controls the vehicle to perform corresponding actions, such as the electronic igniter opens the circuit, the gear adjustment, etc.

The working process is as follows:

(1) when the vehicle door is opened in a non-starting state, the system starts to work, the main alcohol sensor (A) senses alcohol, the alcohol concentration is analyzed by the alcohol concentration detector, the auxiliary alcohol sensor is triggered to judge the source of the alcohol when the alcohol reaches the national regulation standard of 20mg/100ml, the igniter circuit is disconnected when the driver is confirmed to drink the alcohol, the voice alarm is triggered, and a prompt sound of ' don't want to drink and drive ' is given without influencing other electric equipment;

(2) the igniter of the driver which is accurately identified is always in the disconnection stage, the system is initialized after the pressure sensor disappears, if the vehicle is in the ignition state and does not run, the circuit is disconnected after the pressure sensor signal disappears to enable the engine to be flamed out, the main alcohol sensor continues to work when the driver feels the pressure signal again, and the step (1) is circularly carried out;

referring to fig. 3, the principle of the secondary alcohol sensor is that the speed of alcohol in the air and the time point when the same departure point arrives at each place are different, the speed of the exhaled air in the ground chamber is generally less than 3m/s, the exhaled air diffuses from the departure point to the periphery, and the time when the secondary alcohol sensor B, C, D senses alcohol is different, so that the exhalation source of alcohol can be determined according to the sensed time difference and the distance and wind speed between sensor groups, and whether a driver drinks or not is determined, so as to prevent misjudgment.

(3) When the vehicle is started and in a running state, if the main alcohol sensor detects alcohol and exceeds the standard, the vehicle is controlled to be in a neutral position by the single chip microcomputer control automobile controller, and meanwhile, an alarm mechanism is turned on to give an audible and visual alarm.

It should be particularly noted that the technical scheme has strong anti-fraud capacity, the system is simple in structure, low in cost and convenient to manufacture, the source of the exhaled alcohol can be intelligently and accurately detected, a driver can be distinguished from drunk or other passengers can drink the alcohol, the defects of the existing system are overcome, the processing is proper before starting and in the driving process, the pressure sensor is additionally arranged to prevent the fraudulent behavior that one person starts one person to drive, drunk driving is completely stopped in the true sense, the life and property safety of people is ensured, and the harm of drunk driving to the society is reduced.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
