Abstract
一种可防作弊酒精锁系统，该系统包括：位于汽车座椅内压力敏感的压敏电阻，检测驾驶员是否就位；对驾驶员呼出气体进行酒精浓度检测的酒精探头，检测酒精含量是否合格；用于控制汽车启动电路的点火继电器；以及用作数据处理中心的微控制器。由驾驶员对汽车座椅产生的压力信号触发整个装置启动，这保证了每次启动机车前或者更换驾驶员时都要对驾驶员进行酒精浓度检测。本发明可有效预防驾驶员机车离车酗酒以及由非醉酒人员吹气后下车再由醉酒人员上车驾驶的情况，同时可以解决必须通过身份识别才能启动机车的检测方式中。本发明可以在现有酒精检测设备上，通过简单改造就可实现酒精检测设备的可防作弊控制。
An anti-cheating alcohol lock system, the system includes: a pressure-sensitive varistor located in the car seat to detect whether the driver is in place; an alcohol probe to detect the alcohol concentration of the driver's exhaled breath to detect whether the alcohol content is qualified ; the ignition relay used to control the starting circuit of the car; and the microcontroller used as the data processing center. The pressure signal generated by the driver on the car seat triggers the start of the whole device, which ensures that the driver's alcohol concentration will be tested every time before starting the locomotive or when changing the driver. The invention can effectively prevent the situation that the driver of the locomotive gets drunk after leaving the car, and the non-drunk person gets off the car after blowing air, and then the drunk person gets on the car and drives, and at the same time, it can solve the detection method that the locomotive must be started only through identification. The invention can realize the anti-cheating control of the alcohol detection equipment through simple modification on the existing alcohol detection equipment.
Description
Technical field
The present invention relates to a kind of vehicle carried driving alcohol detecting device of practising fraud of preventing, specifically is a kind of social danger that produces to current drunken driving and be applied to the alcohol lock system of practising fraud that prevents of mobile traffic equipment.
Background technology
Drunken driving all is the arch-criminal of car crash in countries in the world.Though drunken driving hidden danger is heavy, still there are many drivers to have psychology lucky or challenge in arms, drinking drive behavior remains incessant after repeated prohibition.
For preventing drunken driving, do one's utmost in various countries, trick the more, wherein high-tech is in the on important role of bringing into play of anti-drunken driving." alcohol lock " installed by many countries on automobile, utilize high-tech means forcibly to retrain driver's drinking drive behavior.
The alcohol lock is a kind of vehicle-mounted alcohol detecting device.The driver wants start a car, and the alcohol content tester that just must be equipped with to the alcohol lock is earlier give a puff, and after instrument test assert that the driver does not drink, automobile can normally start, and when alcohol content surpassed specified value in the expiration, automobile can't start.Alcohol lock be applied in the quantity that has reduced drunken driving to a certain extent, still, the people who does not please drink blows, start automobile through alcohol screen test after, the situation of being driven by the drunken drivers again is also of common occurrence.The control drunken driving remains problem demanding prompt solution.
Summary of the invention
To the problems referred to above, the present invention aims to provide a kind of formula alcohol lock system that can prevent practising fraud reliably, efficiently, and this alcohol lock can not only measure accurately whether alcohol content exceeds standard in the chaufeur body, and can prevent effectively that others from replacing carrying out the situation of alcohol detection.
Anti-cheating formula alcohol lock provided by the invention system comprises:
---microcontroller: data processing center is used to receive the signal that alcohol sensor sends, and warning device and ignition relay is sent control command;
---voltage sensitive sensor: link to each other with above-mentioned microcontroller, be installed under the operator's saddle, in the time of will having detected chaufeur and sit down, the detected signal of voltage sensitive sensor after the A/D conversion, is sent to microcontroller analysis through amplification filtering;
---alcohol detecting device: link to each other with above-mentioned microcontroller, be used to detect the alcohol content of chaufeur breath, through wireless mode the electric signal of alcohol detection is sent into microcontroller and carry out analyzing and processing;
---warning device: be connected with above-mentioned microcontroller, receive the alerting signal of microcontroller, when the chaufeur alcohol concentration exceeds standard, carry out sound and light alarm;
---near ignition relay: be connected with above-mentioned microcontroller, be installed on the car engine, be used to carry out the control command that microcontroller is sent, realize closing or opening of engine.
Among the present invention, being provided with when requiring each chaufeur to come back to seat startup automobile of the interior pressure-sensitive resistive device of seat all will be carried out alcohol detection, and this gets off the situation of being got on the bus and being driven by drunk personnel again after having been avoided non-drunk personnel to blow.
Compared with prior art, the invention has the advantages that and to prevent effectively to get off the situation of getting on the bus and driving by drunk personnel again after non-drunk personnel from blowing.
Description of drawings
Fig. 1 is for preventing practising fraud alcohol lock system hardware block diagram;
The specific embodiment
Embodiment 1
Fig. 1 is the alcohol lock system hardware block diagram of can preventing practising fraud.The detected pressure signal of voltage sensitive sensor is through amplification filtering, and A/D is sent to microcontroller after transforming in real time.Appropriate threshold (body weight with light adult is reference) is set in microcontroller, and the pressure signal that arrives when pressure-sensitive electric circuit inspection explains that chaufeur is not in place temporarily during less than threshold value, and microcontroller is failure to actuate; The pressure signal that arrives when pressure-sensitive electric circuit inspection is during greater than threshold value, and microcontroller sends start signal, and the alcohol detection system starts working.Result of a measurement after alcohol detecting device is changed A/D is sent into microcontroller through wireless transmission method.Microcontroller is controlled the mode of operation of warning device and ignition relay according to result of a measurement.When alcohol detection was qualified, ignition relay was closed, and automobile can normally start; During the alcohol detection nonconformity, alarm activation carries out sound and light alarm, and ignition relay is broken off, and automobile can't start.In the whole process, leave main operator's saddle in case voltage sensitive sensor detects chaufeur, microcontroller sends reset signal; The alcohol detection system quits work, and ignition relay is broken off, automobile flameout; When chaufeur was sat down again, alcohol detecting device restarted, and carried out the next round test;
Embodiment 2
The concrete method of application of this system:
1. when chaufeur was sitting on the seat, pizo-resistance (being pressure sensor) was converted into electric signal with its pressure to seat, and electric signal is through amplification filtering, and A/D transforms back input microcontroller;
2. signal numerical value surpasses the threshold value that pressure-sensitive circuit is provided with, and microcontroller starts the alcohol detection circuit;
3. alcohol detecting device starts, and breath is detected, and result of a measurement is transported to microcontroller;
4. microcontroller carries out analysis and judgement to the alcohol content of gas, if content is in the normal range, and then normal starting ignition device, on the contrary then warning device sounds, and closes ignition device.
In this process, in case chaufeur leaves the seat, alcohol detecting device quits work; When chaufeur is sitting on the main operator's saddle again; Alcohol detecting device restarts, and prevents to get off the situation of being got on the bus and being driven by drunk personnel again after non-drunk personnel from blowing to reach.
