Abstract
An automobile controller for limiting drunk driving comprises an alcohol gas sensor, a monostable trigger circuit consisting of a composite amplifying circuit and a time-base circuit, and a relay; after an alcohol gas signal collected by the alcohol gas sensor is treated by the monostable trigger circuit, a control signal is output to the relay from the output end of the monostable trigger circuit, and operation of an electronic igniter in an automobile circuit is controlled by the relay. In the utility model, the alcohol gas sensor is adopted for collecting the signal of the alcohol gas, and by the design of the composite amplifying circuit and the time-base integrated circuit, input impedance of the control part is improved, so that the sensitivity of the signal of the alcohol gas is ensured, and simultaneously, the stability of the output of the time-base circuit is ensured, the relay is controlled to power on timely, and the electronic igniter can not start. The problem that a drunk driver can not control driving is solved, and the safety of drivers and other relative personnel is better protected.
Description
Technical field
The utility model belongs to modernized safety precaution electronic technology field, and particularly a kind of automobile limits driving controller after drinking.
Background technology
In the modern transportation field, automobile has become one of requisite vehicle, safe driving has been that problem, especially drunken driving on record, that generally worry give steerman and serious consequence that other people cause to become the focal issue that society attractes attention.So need be except the generation of restricting traffic consequence technically from traffic method and strict law enforcement.
Summary of the invention
The purpose of this utility model is to solve drunken driving cause the problem of serious consequence may for chaufeur and other people, provides a kind of automobile to limit driving controller after drinking.
The automobile that the utility model provides limits driving controller after drinking, comprise that ethanol gas dependent sensor, univibrator circuit and the relay be made up of composite amplifier and time base circuit constitute, after the alcohol gas signal process univibrator processing of circuit that the ethanol gas dependent sensor is gathered, give the relay output circuit by the mouth of univibrator circuit output control signal, and by the work of the Ignition Module in the relay output circuit Control of Automobile circuit.
The input end of the composite amplifier in the said univibrator circuit connects the sensitive resistance of regulating, time base circuit input end direct connection composite amplifier mouth, the time base circuit mouth is connected directly to relay, relay over the ground between the series connection one light-emitting diode.
Advantage and good effect:The utility model adopts the ethanol gas dependent sensor to gather the alcohol gas signal, design through composite amplifier and time-base integrated circuit, improved the input impedance of control part, make the sensitivity of alcohol gas signal be guaranteed, guaranteed the stability of time base circuit output simultaneously, the conducting of control relay in time, and the Control of Automobile Ignition Module can't start.Solved because of the uncontrollable problem that drives a car after drinking, protected chaufeur and other related personnel's safety better, made society harmonious more stable.
Description of drawings
Fig. 1 is that the automobile that the utility model provides limits the driving controller block diagram after drinking;
Fig. 2 is that automobile limits the driving controller schematic circuit diagram after drinking.
The specific embodiment
As shown in Figure 1, the automobile that the utility model provides limits driving controller after drinking, comprises that ethanol gas dependent sensor CM900, univibrator circuit and the relay be made up of composite amplifier and time base circuit constitute.
The alcohol gas signal that CM900 gathers is input relay after composite amplifier and time base circuit processing, by the Ignition Module work in the relay Control of Automobile circuit.
, the alcohol molecule strong problem such as fast of volatilizing easily at the bad collection of alcohol gas, dynamic, at first adopt composite amplifier, triode BG1 is connected into penetrates a grade follower, improved control part input impedance, guaranteed that the alcohol gas signal that CM900 gathered is in time amplified by collection, and export to relay through time-base integrated circuit accurately and effectively, guaranteed stability, the reliability (Fig. 1) of sensitivity.
This automobile limits the physical circuit of driving controller after drinking referring to Fig. 2, for obtaining good in-use performance, at the mouth of the IC1CM900 adjustable resistance R2 that connects, to regulate the sensitivity of alcohol gas, BG1 is connected into emitter follower, it has high input impedance, low output impedance, characteristics that incoming signal is identical with phase of output signal, has improved the input impedance of control part, has guaranteed the sensitivity of CM900.Use BG1 and BG2 compound circuit to obtain amplifying signal the most accurately, this characteristic is exported in the pulse that the univibrator circuit that utilizes time base circuit IC2 to form can make input pulse be shaped to fixed width, has solved problems such as the narrow or wide input pulse signal distortion of the alcohol gas signal gathered, instability.Circuit working when opening lock K1, IC1 detect the alcohol gas signal, and BG1BG2 is conducting in succession, and IC2 is output as high level relay adhesive J1 and disconnects, and automobile can't start.No-voltage output when IC1 does not detect alcohol signal, IC2 output low level relay is not worked, the automobile normal operation.R3, R4 are biasing resistor; D1 is a zener diode, to guarantee the stable of power supply voltage; D2 is a light emitting diode, and is when detecting alcohol signal, glittering.
