Abstract
The utility model discloses a vehicle-mounted alcohol detection system. The vehicle-mounted alcohol detection system comprises a receiving module, an emitting module connected with the receiving module, a car power supply module, an igniting device, a headlamp, a loudspeaker and an indication lamp, wherein the emitting module is connected with a signal detection device. According to the vehicle-mounted alcohol detection system, an emitting part is very small and is separated from a receiving part, so that the system can be carried with a user and no any complicated operation is performed; and meanwhile, the receiving part is mounted on a car and difficult to dismount, so that a good effect for preventing drunk driving is achieved and a good promotional value in practical application is obtained.
Description
Technical field
The utility model relates to a kind of vehicle-mounted alcohol detection system.
Background technology
Whether at present, nearly all country all adopts the expiration alcohol tester that navigating mate is carried out the scene and detects, drink to confirm measured chaufeur.Alert of a great variety on the market now with alcohol tester; Along with the development of technology, function is more and more stronger, sensitivity is increasingly high, and whether it can effectively assist the traffic police to fix a point to spot-check chaufeur to drink; But, therefore can't well control driving when intoxicated because faciostenosis is implemented in selective examination.
Summary of the invention
The main purpose of the utility model is to provide a kind of use simple, reliable, the vehicle-mounted alcohol detection system that the phenomenon of can more general control driving when intoxicated takes place.
A kind of vehicle-mounted alcohol detection system of the utility model comprises receiver module, and the transmitter module, automobile supply module, ignition device, headlight, loudspeaker, the indicator lamp that link to each other with receiver module, and said transmitter module is connected with signal supervisory instrument.
Further, said transmitter module is provided with alcohol sensor, microphone and micro controller system.
Further, said receiver module is provided with micro controller system, indicating module, relay, A/D change-over circuit and phonetic alarm device.
The vehicle-mounted alcohol detection system of the utility model because radiating portion is very little, and separates with receiving unit, can be carried, and does not need any complex operations; Receiving unit is installed on the automobile simultaneously, is difficult for unloading, and therefore prevention being driven when intoxicated has good effect, in practical application, has excellent popularization and is worth.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing:
Fig. 1 is the circuit block diagram of the utility model vehicle-mounted alcohol detection system.
The specific embodiment
As shown in Figure 1, a kind of vehicle-mounted alcohol detection system of the utility model comprises receiver module; And the transmitter module, automobile supply module, ignition device, headlight, loudspeaker, the indicator lamp that link to each other with receiver module, said transmitter module is connected with signal supervisory instrument, and this system can be placed on the automobile instrument panel position; When driver's start a car, warning device will sound, and reminds chaufeur to use alcohol-detection and safety control system; This moment, driving engine was in by the lock state, and automobile can't start.After the alcohol sensor heating, system's indicating module green light lights, and the prompting chaufeur is exhaled.Detect for preventing that chaufeur from escaping, a microphone is set as the expiration judgment means.After the affirmation of exhaling, micro controller system sends energizing signal, begins the gas signal that alcohol sensor is surveyed is detected.Because alcohol content and alcohol sensor detect the proportional relation of voltage signal that the back produces, thereby can carry out the judgement of alcohol content according to voltage signal.Detection signal carries out converting digital signal into through A/ D change-over circuit after signal amplification and the filtering through amplification, detecting circuit; By micro controller system this signal is handled judgement, suppose that alcohol content does not exceed standard, indicator lamp lights; Control relay is inoperative, and automobile can start; Otherwise the indicator lamp that exceeds standard lights, and warning device sounds simultaneously, and explanation can not be gone, if the driver starts by force, control relay cuts off the ignition device power supply, and automobile can't be gone, thereby realizes the function that control is driven when intoxicated.
Wherein, said transmitter module is provided with alcohol sensor, microphone and micro controller system, and said receiver module is provided with micro controller system, relay, indicating module, A/D change-over circuit and phonetic alarm device.
The vehicle-mounted alcohol detection system of the utility model because radiating portion is very little, and separates with receiving unit, can be carried, and does not need any complex operations; Receiving unit is installed on the automobile simultaneously, is difficult for unloading, and therefore prevention being driven when intoxicated has good effect, in practical application, has excellent popularization and is worth.
The foregoing description; It is an instance of the utility model; Be not enforcement and the interest field that is used for limiting the utility model, all or technical schemes of being equal to identical with the said content of the utility model claim all should be included in the utility model protection domain.
