Smell and visit terminal and be used for alcohol concentration in the real-time inspection vehicle, therefore, smell the installation site of visiting terminal and should be convenient to detect alcohol concentration, for example, can be installed in it on bearing circle or rearview mirror next door etc. gathered the position of driver's breath easily.Simultaneously, detect effect, can the while a plurality of positions (for example a plurality of positions around the driver) in car install and smell the spy terminal for strengthening.
Smell the spy terminal and link to each other, transmit testing result to mobile communication module with mobile communication module.According to national quality supervision and inspection quarantine office " vehicle drive personnel blood, breath alcohol concentration threshold value and check " national standard on May 31st, 2004 issue, the alcohol content in the vehicle drive personnel blood more than or equal to 20 milligrams/100 milliliters, be driver from drunk driving less than 80 milligrams/100 milliliters; Alcohol content in the blood is greater than or equal to 80 milligrams/100 milliliters and is drunk driving.Simultaneously, in conjunction with existence general knowledge, the back steering vehicle of slightly drinking generally can not influence drive safety, and when reaching drunk degree when drinking, will there be major safety risks in steering vehicle.Therefore, in actual implementation process, can preestablish an alarm threshold, detect the alarm command that just comprises testing result when alcohol concentration is higher than this alarm threshold in the car to the mobile communication module transmission when smelling the spy terminal.This threshold value can be set according to own physique of driver and alcohol level.Mobile communication module and mobile communications network communicate to connect, receive smell visit the alarm command that terminal sends after, provide the alarm information that comprises testing result and information of vehicles (such as but not limited to owner information, vehicle model, the number-plate number etc.) to travel conditions supervision side (such as but not limited to traffic control center) by mobile communications network.Except that mobile communication function, mobile communication module also can obtain the current location information of himself according to the mobile base station that it inserted.Because each mobile base station all covers the geographic range of limited size, therefore, can be by the approximate position that draws vehicle, present position, mobile base station.
The vehicle-mounted receiver of GPS links to each other with mobile communication module, is used for receiving in real time gps signal, generates current location information (such as but not limited to the information such as longitude, latitude and travel direction of current location).Current location information will mail to travel conditions supervision side by above-mentioned alarm information, so that the driver that drives when intoxicated is taked to tackle speed limit, operation such as parking by force by force.
Smell the spy terminal and also link to each other with alarm module, alcohol concentration in alarm module report car is sent the alarm indication by alarm module again.This alarm indication can be such as but not limited to alarm indicator, alarm prompt sound etc., and alarm indicator can also be such as but not limited to the pilot lamp of alerting drivers and caution surrounding vehicles and pedestrian's pilot lamp.The alarm indication that this alarm indication can be set to corresponding with testing result, different detection triggers has nothing in common with each other, and for example only when detecting when seriously driving when intoxicated behavior, just waits by caution and warns surrounding vehicles and pedestrian.Therefore, store a plurality of alcohol concentration grades in the alarm module, for example slightly drink, low alcohol consumption, excessive consumption of alcohol, excessive drinking etc., the operational order that each alcohol concentration grade is corresponding different is for example sent voice suggestion (reminding the driver), sends car light prompting (reminding other vehicles and pedestrian), is triggered mobile communication module and upload information etc.Alarm module receives to smell visits the alcohol concentration value that terminal is sent, and compares with each alcohol concentration grade, sends corresponding operational order.
The reaction velocity test module is visited terminal and is linked to each other with smelling, be used to receive smell and visit the interior alcohol concentration of car that terminal is sent, send and the corresponding reaction velocity test problem of each alcohol concentration grade by voice mode then, the reaction velocity of test driver is assessed the risk of driving when intoxicated.For example, visit terminal and detect when slightly drinking situation smelling, can notice reaction velocity test module send corresponding (because only for slightly drinking, therefore the difficulty of test question can be higher relatively) the reaction velocity test problem, the higher arithmetic of complexity topic for example, for example " how many 16 * 9+22 * 7+55 equals? "When driver's erroneous answers or when not providing answer within a certain period of time, the reaction velocity test module can automatic reduction problem complexity; And when the driver provided answer very soon, then the reaction velocity test module can increase problem difficulty automatically.Then, through after the several times tests, wrong situation and driver are provided the reaction velocity that the used feedback informations such as time of answer come the Comprehensive Assessment driver according to the complexity of the problem of detection, answer.Because reaction velocity also can show the clear-headed degree that the driver is current, therefore also can surpass this threshold value to the reaction velocity setting threshold, then there is great driving hidden danger in explanation.Therefore, when the reaction velocity that records surpasses predetermined threshold, the reaction velocity test module can mail to mobile communication module with the reaction velocity that draws (visiting alcohol concentration in the car that terminal sends at first together with smelling), be included in and send to travel conditions monitoring side in the alarm information, make that the travel conditions monitoring can be to come the current safety coefficient of driving of comprehensive evaluation driver in conjunction with alcohol concentration in the car and driver's reaction velocity parameter.It should be noted that and remove the arithmetic outlying, also can use the other problems that all can the test driver reaction velocity.
