Abstract
The utility model relates to a drunk-driving reminder in the field of electronic alarms. The drunk-driving reminder adopts the technical proposal that a potentiometer W is connected with an alcohol sensor IC1, a triode T1, a resistor R2 and a resistor R1 to achieve an alcohol concentration detection circuit; a time-base integrated circuit IC2 is connected with a triode T2, a resistor R3 and a buzzer 3 to achieve an audio-signal control circuit; and the two circuits are connected with a feed circuit consisting of a battery DC and a switch K by a Zener diode DW. The drunk-driving reminder is simple in structure and convenient in manufacture, and effectively reminds drivers not to drive after drinking, therefore realizing the purpose of safe driving.
Description
Technical field
The utility model relates to a kind of reminiscences of driving when intoxicated in the electronic alarm field.
Background technology
China's vehicle is more and more at present, and the traffic accident that takes place because of driving when intoxicated is very serious.Present alcohol detection mechanical discipline is strong, cost is high, is difficult for promoting the use of.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, and the reminiscences of driving when intoxicated that a kind of cost is low, be easy to popularize use is provided.
Its technical scheme is: potential device W connects alcohol sensor IC1, aerotron T1 and resistance R 2, resistance R 1 are formed the alcohol concentration testing circuit; Time-base integrated circuit IC2 connects aerotron T2, resistance R 3, buzzer phone L composition audio communication control circuit; Above two parts circuit is connected on the feed circuit of battery DC and K switch composition by zener diode DW.
The utlity model has simple in structurely, easy to make, be installed in the vehicle and can effectively point out the driver not drive when intoxicated, play the purpose that guarantees safe driving.
Description of drawings
Accompanying drawing is the schematic circuit diagram of a kind of embodiment.IC1 is alcohol sensor (CM900) among the figure; IC2 is time-base integrated circuit (NE555); L is a buzzer phone; K is former car key switch; DC is former car storage battery.
The specific embodiment
Be further described below in conjunction with accompanying drawing: potential device W connects alcohol sensor IC1, aerotron T1 and resistance R 2, resistance R 1 are formed the alcohol concentration testing circuit; Time-base integrated circuit IC2 connects aerotron T2, resistance R 3, buzzer phone L composition audio communication control circuit; Above two parts circuit is connected on the feed circuit of battery DC and K switch composition by zener diode DW.
Circuit is connected, and opens key switch K, and at ordinary times, alcohol sensor IC1 did not detect less than alcohol signal when the driver drank, and a point output low level aerotron T1, T2 end, and the 3 pin output low level buzzer phone L of time-base integrated circuit IC2 are noiseless.
After drinking, the driver drives, alcohol sensor IC1 detects alcohol concentration and exceeds standard behind the signal, the a point output high level of alcohol sensor IC1, aerotron T1, T2 conducting, 2,6 pin of time-base integrated circuit IC2 become low level, 3 pin output high level buzzer phone L gets electric sounding, and the prompting driver does not drive.
Claims (1)
1, a kind of reminiscences of driving when intoxicated is characterized in that: potential device W connects alcohol sensor IC1, aerotron T1 and resistance R 2, resistance R 1 are formed the alcohol concentration testing circuit; Time-base integrated circuit IC2 connects aerotron T2, resistance R 3, buzzer phone L composition audio communication control circuit; Above two parts circuit is connected on the feed circuit of battery DC and K switch composition by zener diode DW.
