Description
Technical field
The utility model is related to traffic safety driving technology fields, more particularly, to a kind of vehicle-mounted drunk driving detector.
Background technology
With economic rapid growth, car ownership is increased with millions of speed every year in China, due to driving
Member can not effectively be controlled after drinking, driven when intoxicated and happened occasionally, therefore the traffic accident generated is quite a few.Driver at present
The detection mode whether driven when intoxicated is after traffic police stops suspect vehicle, by detecting the wine contained in the gas that driver breathes out
The number of smart content is driven when intoxicated to judge whether driver belongs to, and this mode can not remind driver will be into serving a round of liquor to the guests in advance
It drives so that driver drives in enterprising serve a round of liquor to the guests of road, causes unnecessary traffic accident.In order to remind driver whether will in advance
It carries out drunk driving to be in the prior art mounted directly drunk driving detector in the car, is fabricated to vehicle-mounted drunk driving detector and is driven to detect
Whether personnel have potable spirit drink, and this drunk driving detector needs driver actively to open drunk driving detector switch, to coordinate
Alcohol detection is done, the shortcomings that vehicle-mounted drunk driving detector is：It needs driver to have certain subjective initiative and takes do-it-yourself wine
Essence detection, can not carry out self-action detection, be easy to be ignored by driver, to carry out drunk driving, cause traffic accident.
Utility model content
The technical problem to be solved by the utility model is to provide it is a kind of it is simple in structure, can be detected automatically it is vehicle-mounted
Drunk driving detector.
The utility model is the technical scheme adopted is that a kind of vehicle-mounted drunk driving detector, including alcohol detecting device, alcohol
Detection device includes pressure detection circuit and the pressure inspection being arranged below main driving seat for detecting main driving seating state
The control circuit of slowdown monitoring circuit connection, the broadcaster being connect with control circuit, the alcohol screen test circuit that is connect with control circuit and
The alarm being connect with alcohol screen test circuit.
The utility model has the beneficial effects that：Using above-mentioned vehicle-mounted drunk driving detector, when driver is seated to main driving seat
On position, pressure detection circuit detects the case where main driving seat is pressurized, and alcohol detecting device is according to the main driving seat detected
Position compression situation has been enter into get driver in vehicle, and actively triggering triggering broadcaster broadcasts at this time, notifies driver
Alcohol detection is carried out, and triggers alcohol screen test circuit and carries out alcohol detection, artificial alcohol content tester of pressing is avoided and switchs to examine
Survey whether can drunk driving, which takes a seat situation and carries out alcohol detection automatically according to driver's, and according to inspection
It surveys result to alarm, whether active warning driver is simple in structure in drunk driving, easy to operate, highly practical.
As priority, control circuit includes the power supply that central processing unit is connect with central processing unit, and central processing unit uses
Using MSP430F147 chips, MSP430F147 chips have the characteristics that equipment low in energy consumption, to be suitable for that battery is used for a long time.
As priority, pressure detection circuit includes pressure detection switch S1, the interface KEY_ being connect with central processing unit
CHK changes the state of pressure detection switch S1 to change the electricity of interface KEY_CHK when driver is seated on main driving seat
It is flat, so that central processing unit is got the state of switch.
As priority, alcohol screen test circuit includes the clock circuit being connect with central processing unit, is connect with central processing unit
Alcohol sensor, the inflatable mouth that is arranged near vehicle steering wheel, alcohol sensor uses C8051F040 chips, using this
Structure, broadcaster carry out broadcast prompt driver and carry out alcohol detection, and driver is passed by blowing to inflatable mouth by alcohol
Whether alcohol content is exceeded to detect driver for sensor, and C8051F040 chips have the function of alcohol concentration test and monitoring.
Description of the drawings

Specific implementation mode
Utility model is further described referring to the drawings and in conjunction with specific implementation mode, to enable those skilled in the art
It can implement according to this with reference to specification word, scope of protection of the utility model is not limited to the specific implementation mode.
The utility model is related to a kind of vehicle-mounted drunk driving detector, including alcohol detecting device, alcohol detecting device includes setting
It sets and is used to detect the pressure detection circuit 1 of main driving seating state below main driving seat, connect with pressure detection circuit 1
Control circuit 2, the broadcaster 3 being connect with control circuit 2, the alcohol screen test circuit 4 and and alcohol detecting being connect with control circuit 2
Try the alarm 9 that circuit 4 connects.
As priority, control circuit 2 includes the power supply that central processing unit 5 is connect with central processing unit 5, central processing unit 5
Using using MSP430F147 chips.
As priority, the interface KEY_ that pressure detection circuit 1 includes pressure detection switch S1, connect with central processing unit 5
