Description

The anti-drunk driving system of intelligence

Technical field

The utility model relates to intelligent anti-drunk driving system.

Background technology

The traffic accident of China's majority is all driven when intoxicated and is caused due to chaufeur, prevents that system that chaufeur drives when intoxicated from, as a kind of emerging field, being paid attention to by increasing people.At present, the system that prevents chaufeur drunk driving on market is roughly divided into two kinds: car key is reequiped, at installation detecting device on the key, make chaufeur cannot open car door or start vehicle after drinking; Vehicle itself is reequiped, and installation detecting device in car, cuts off vehicle ignition circuit.But no matter which kind of mode, all needs the key to vehicle or itself carries out repacking to a certain degree, and process is loaded down with trivial details.Meanwhile, these devices just prevent that chaufeur from entering or start a car, do not provide more guarantee to drunk personnel's safety, tend on the contrary make chaufeur under severe, cold snap, and health of human body is endangered safely.

Utility model content

The deficiency existing for solving prior art, the utility model discloses intelligent anti-drunk driving system, this system can allow drink-driving person vehicle startup but can not exercise, native system can ensure that chaufeur uses other functions of vehicle, meet on the basis of its needs, prevent that steering vehicle from causing Peril Incident.

For achieving the above object, concrete scheme of the present utility model is as follows:

The anti-drunk driving system of intelligence, comprise MQ-3 alcohol detection sensor, the probe of described MQ-3 alcohol detection sensor is arranged on the position facing to chaufeur left side of head, MQ-3 alcohol detection sensor detection signal is sent to the input end of micro controller system, the output driving clutch self-locking module action of micro controller system, power-transfer clutch self-locking module is arranged on the power-transfer clutch back lower place.

Described power-transfer clutch self-locking module comprises the large torsion steering wheel of MG995, and the large torsion steering wheel of MG995 and baffle plate are coaxially connected on the support of self-locking clutch.

Micro controller system is STC90C51RD+ micro controller system, and power-transfer clutch self-locking module is mainly made up of parts such as the supports of the large torsion steering wheel of MG995, self-locking clutch.Wherein, MQ-3 alcohol detection installation of sensors is facing to the position of chaufeur left side of head, and more close motorist, rather than passenger prevent from drinking of other staff being detected and cause vehicle not travel.Between STC90C51RD+ micro controller system and other devices, be connected by data line, micro controller system and each module are powered by vehicle power.

In the time that MQ-3 alcohol detection sensor detects that chaufeur drink is driven when intoxicated, can be by data line by data information transfer to STC90C51RD+ micro controller system, STC90C51RD+ micro controller system can be controlled the large torsion steering wheel of MG995 90-degree rotation afterwards, baffle wedge is on power-transfer clutch, make chaufeur cannot step on power-transfer clutch, and then cannot drive a car.

The beneficial effects of the utility model:

Can prevent that drunken driving person's steering vehicle from causing potential safety hazard, simultaneously not hinder chaufeur to enter vehicle and use the systems such as air-conditioning in car, to ensure the health of human body safety of chaufeur, install simple, without the structure that changes car.

Fig. 2 the utility model power-transfer clutch and baffle plate connection diagram;

In figure, 1, power-transfer clutch, 2, baffle plate.

The specific embodiment:

Below in conjunction with accompanying drawing, the utility model is elaborated:

As shown in Figure 1-2, the anti-drunk driving system of intelligence, comprise MQ-3 alcohol detection sensor, the probe of described MQ-3 alcohol detection sensor is arranged on the position facing to chaufeur left side of head, MQ-3 alcohol detection sensor detection signal is sent to the input end of micro controller system, the output driving clutch self-locking module action of micro controller system, power-transfer clutch self-locking module is arranged on power-transfer clutch 1 back lower place.

Described power-transfer clutch self-locking module comprises the large torsion steering wheel of MG995, and the large torsion steering wheel of MG995 and baffle plate are coaxially connected on the support of self-locking clutch.

Micro controller system is STC90C51RD+ micro controller system, and power-transfer clutch self-locking module is mainly made up of parts such as the supports of the large torsion steering wheel of MG995, self-locking clutch.Wherein, MQ-3 alcohol detection installation of sensors is facing to the position of chaufeur left side of head, and more close motorist, rather than passenger prevent from drinking of other staff being detected and cause vehicle not travel.Between STC90C51RD+ micro controller system and other devices, be connected by data line, micro controller system and each module are powered by vehicle power.

In the time that MQ-3 alcohol detection sensor detects that chaufeur drink is driven when intoxicated, can be by data line by data information transfer to STC90C51RD+ micro controller system, STC90C51RD+ micro controller system can be controlled the large torsion steering wheel of MG995 90-degree rotation afterwards, baffle plate 2 is stuck on power-transfer clutch 1, make chaufeur cannot step on power-transfer clutch, and then cannot drive a car.

Claims (1)

1. intelligent anti-drunk driving system, it is characterized in that, comprise MQ-3 alcohol detection sensor, the probe of described MQ-3 alcohol detection sensor is arranged on the position facing to chaufeur left side of head, MQ-3 alcohol detection sensor detection signal is sent to the input end of micro controller system, the output driving clutch self-locking module action of micro controller system, power-transfer clutch self-locking module is arranged on the power-transfer clutch back lower place;

Described power-transfer clutch self-locking module comprises the large torsion steering wheel of MG995, and the large torsion steering wheel of MG995 and baffle plate are coaxially connected on the support of self-locking clutch.
