Description
Technical field
The present invention relates to alcohol concentration field of measuring technique, more specifically, more particularly to a kind of anti-based on multisensor
The vehicle-mounted alcohol concentration measurement equipment of interference.
Background technology
In recent years, in the major traffic accidents that China occurred, nearly 1/3rd are caused by driving when intoxicated.Cause
This, the detection to driver's Drinking level is just increasingly paid attention to, and alcohol concentration monitor is gradually widely applied.Wine
Smart concentration monitor acts not only as traffic police and rapidly and accurately judges the forensic tools whether driver drives when intoxicated, while
Can be used for driver and test oneself whether to drink beyond one's capacity.
At present, domestic main still some conventional methods of detection to driving when intoxicated, i.e., surveyed with hand-held expiration alcohol
Examination instrument and the inspection of headspace gas chromatography instrument blood alcohol.Test by handing over police handheld tester for alcohol concentration scene to stop, it is this
There is very big defect in passive detection mode, the problems such as such as alcohol concentration testing precision is inadequate.
The content of the invention
It is an object of the invention to provide a kind of be based on the jamproof vehicle-mounted alcohol concentration measurement equipment of multisensor, fusion
Environmental disturbances correcting algorithm, improves the precision of wine inspection.
One kind is based on the jamproof vehicle-mounted alcohol concentration measurement equipment of multisensor, including alcohol detection module, vehicle-mounted master
Control module, LCD LCD MODULEs, LED indicating modules, voice alarm module and engine control module.Alcohol detection module
Using electric nasus system, comprising gas sensor array, Signal Pretreatment unit and Fuzzy Pattern Recognition unit.Gas sensor
Array equivalent to primary Olfactory Receptor Neurons, by 6 Metal Oxide Semiconductor Gas Sensing sensors, humidity sensor, one
Temperature sensor, an oxygen sensor and a Smoke Sensor are constituted, and are produced in a unit module.
Semiconductor alcohol sensor has very high sensitivity and good selectivity to alcohol vapour, with small volume, essence
The characteristics of degree height, response fast, inexpensive and strong antijamming capability.In measurement range, in the bulk resistor and air of the sensor
The close linear relationship of alcohol content, can be to improve detection essence by the way that the change of resistance to be converted into the voltage change of easy measurement
Degree and reliability, using the method for many alcohol sensor detection information fuzzy Fusions.
Using humidity sensor（People's expiration humidity relative constancy, and generally greater than driver environment's air humidity）, oxygen
Sensor（People's expiration oxygen content is significantly less than driver environment's air oxygen content）, temperature sensor（People's expired gas temperature one
As be higher than driver environment's air themperature）Deng combination, improve alcohol screen test precision and complete people's expiration confirmation.When such as exhaling, oxygen
Gas sensor can detect being obviously reduced for oxygen content, and temperature sensor can detect temperature and substantially rise, only the two
Condition meets simultaneously, and just can be considered to exhale confirms.
Because alcohol sensor has certain dependence to the humiture of surrounding environment, so the precision to improve detection
With exclusion ambient influnence, the complexity weather such as winter low temperature and low humidity and summer high-temperature high humidity is adapted to, in circuit temperature and humidity compensation is added.
It has been investigated that, oxygen concentration is almost constant in expiration, and the oxygen content in people's expiration is under 760mm mercury column
15% is constituted about, the oxygen concentration in air is about 20%.It is identical with the ratio that alcohol is diluted according to oxygen in expiration, draw
The alcohol concentration of correction.Oxygen calibrates alcohol concentration method and humidity calibration alcohol concentration method is significantly reduced because of expiration quilt
Dilution proportion and the impact of alcohol sensor output pulsation that causes immediately, effectively increases the precision of alcohol detection.
During in view of the indoor wine inspection of driving, in addition to the interference of gasoline smell, it is also possible to have smoking to cause smog to do
Impact sensor coefficient is disturbed, so the detection accuracy in order to improve system, increases a Smoke Sensor, using it cigarette is excluded
Mist is disturbed.
Further, the humidity sensor, using HIH-3610 humidity sensors.
Further, the temperature sensor, using DS18B20 temperature sensors.
Further, the Smoke Sensor, using NIS-09C Ionic Smoke Transducers.
Further, the voice module adopts ISD1730 chips as core parts.The speech chip and the vehicle-mounted master of master
Communicated using SPI modes between control module.When system detectio exceedes setting threshold values to in-car alcohol content, prompting is reported
Sound.
Further, the LCD display module is made up of JD-T1800 liquid crystal display LCD.
Further, the LED light module, is made up of one group of superbright LED light.
Further, the engine control module can connect and access automobile engine circuit and throttle control circuit.
Compared with prior art, the vehicle-mounted alcohol concentration measurement equipment that the present invention passes through multisensor, integrated environment interference
Correcting algorithm, improves the precision of wine inspection.
