Abstract
The utility model provides an on-vehicle alcohol detection device, including the alcohol detector who is arranged in detecting alcohol content in the air, be equipped with a microprocessor who is connected with automobile engine ignition circuit, the alcohol detector inserts microprocessor through an amplifier circuit, and the alcohol detector is installed in the driver's cabin, and microprocessor prevents switching on of automobile engine ignition circuit when alcohol content is too high in the air. The utility model discloses simple to operate, use convenient, detection effect is good.
Description
Technical field
The utility model relates to a kind of alcohol detecting device, particularly a kind of vehicle-mounted alcohol detecting device.
Background technology
Along with economic development, the car opertion amount is more and more, but because of the drive when intoxicated traffic accident that causes of chaufeur also increasing, so the vehicle-mounted alcohol detecting device occurred.Use the mechanical brake that is associated with the ignition system of vehicle as Chinese invention patent 200480043239.1 disclosed a kind of alco key that are used for automobile.Key is used for the mechanical brake of Remote Control Vehicle, and described key comprises the analytical equipment that is used for determining personnel's alcohol level, and is arranged to only send signal to authorize the startup vehicle when alcohol level is lower than predetermined limit grade.This method comprises the following steps: to send opening signal to open at least one car door of this vehicle; Operate this ignition key to start vehicle; Testing staff's alcohol level, and, wirelessly send the OK signal if this grade is lower than predetermined limit grade, OK can start vehicle with expression; Only when described OK signal is received by this mechanical brake, start this vehicle.Opening of car door can be controlled in a similar manner.
But the alcohol content analytical equipment in this technology places in the car key, use inconvenient and far away apart from chaufeur expiration position, so test accuracy such as lowers greatly at problem.
Summary of the invention
The utility model provides a kind of easy to install, vehicle-mounted alcohol detecting device that test accuracy is high.
A kind of vehicle-mounted alcohol detecting device, comprise the alcohol detector that is used for detecting the air alcohol content, also be provided with one with car engine ignition circuit microprocessor linked, alcohol detector inserts microprocessor by an amplifying circuit, described alcohol detector is installed in the operator's compartment, and microprocessor stops the conducting of car engine ignition circuit when alcohol content is too high in the air.
Described alcohol detector is installed in the indoor chaufeur head place of closing on of vehicle drive, wherein alcohol detector is made up of the annunciator of alcohol content analytical equipment and access microprocessor, microprocessor can send signal to annunciator when alcohol content is too high in the air, and the alarm song that annunciator sends can be reminded chaufeur timely.
Description of drawings
Fig. 1 is the structured flowchart of the utility model vehicle-mounted alcohol detecting device;
Fig. 2 is the scheme drawing that the automobile of the utility model vehicle-mounted alcohol detecting device is housed.
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples:
Referring to Fig. 1,2, the utility model vehicle-mounted alcohol detecting device, comprise the alcohol detector 1 that is used for detecting the air alcohol content, also be provided with one with car engine ignition circuit microprocessor linked, alcohol detector 1 inserts microprocessor by an amplifying circuit, and microprocessor and alcohol detector 1 are all by automobile mounted storage battery power supply.
It is interior near near the chaufeur above-head that alcohol detector 1 is installed in operator's compartment, and microprocessor stops the conducting of car engine ignition circuit when alcohol content is too high in the air, causes the ignition lock of pressing the access point ignition circuit also can't start automobile.
Wherein alcohol detector 1 is made up of alcohol content analytical equipment and annunciator, and annunciator adopts buzzer siren.
Wherein when alcohol content is higher than limits value 0.3mg/ml, microprocessor can send signal to the alcohol content analytical equipment after 5 minutes after handling for the first time once more, the alcohol analytical equipment is the alcohol content of the gas of test driver breathing again, reenters determining program.
The utility model can detect alcohol content accurately, and easy for installation, easy to use, can control the behavior of driving when intoxicated by actv..
