Abstract
The utility model relates to a drunk-driving alarm device. When alcohol signal output voltage detected by an alcohol gas sensor IC1 achieves a certain value, a TWH8778 high-power switch element IC2 connected with the alcohol gas sensor IC1 is conducted, the output end of the TWH8778 high-power switch element IC2 is input to the I/O end of a single-chip microcomputer control circuit IC3 through a resistor 1R1, and the single-chip microcomputer control circuit IC3 is output in three ways: in the first way: a low-level signal output from the single-chip microcomputer control circuit IC3 pushes a loudspeaker DBB to beep through a resistor 1R3; in the second way, a level signal output from the single-chip microcomputer control circuit IC3 enables a triode T1 to be conducted through a resistor 1R2, a relay J connected with the output of the triode T1 is actuated, a switch J-1 of the relay J is closed, and an engine stops operating; and in the third way, the single-chip microcomputer control circuit IC3 controls an output driving GSM transmit-receive trigger module IC4 to send alarm information to designated personnel so as to achieve the basic purpose of avoiding traffic accidents.
Description
Technical field
The utility model relates to field of monitoring devices, particularly relates to a kind of drunk driving warning device.
Background technology
In traffic accident, drunken driving occupies very big ratio, though national current law explicit order don, people still are frequent drunken driving, so people are badly in need of a kind of device that can prevent by automatic reminding in the car.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of drunk driving warning device is provided.
The technical scheme that the utility model adopted is such: a kind of drunk driving warning device, comprise alcohol gas sensor IC 1, TWH8778 high-power switch device IC2 and single chip machine controlling circuit IC3, after the energized, when the alcohol signal output voltage of alcohol gas sensor IC 1 detection reaches certain value, alcohol gas sensor IC 1 bonded assembly TWH8778 high-power switch device IC2 connects, the mouth of TWH8778 high-power switch device IC2 is input to the I/O end of single chip machine controlling circuit IC3 through resistance 1R1, single chip machine controlling circuit IC3 divides three tunnel outputs, and the first via is sent the sound that ticks by the low level signal of single chip machine controlling circuit IC3 output through resistance 1R3 promotion loud speaker DBB; The outputs level signals of secondary route single chip machine controlling circuit IC3 makes aerotron T1 conducting through resistance 1R2, the adhesive of aerotron T1 output bonded assembly relay J, and the switch J-1 closure of relay J, driving engine is out of service; Third Road drives GSM transmitting-receiving trigger module IC4 by single chip machine controlling circuit IC3 control output and sends alarm message to the personnel of appointment.
Described alcohol gas sensor IC 1 adopts the QM-NJ9 alcohol gas sensor.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: this device adopts alcohol sensor to gather alcohol signal, drive GSM transmitting-receiving trigger module by Single-chip Controlling and notify family members, make automobile flameout by driving circuit simultaneously, reach system purpose originally, avoid the generation of the accident of traffic.
Description of drawings
Fig. 1 is schematic circuit diagram of the present utility model.
The specific embodiment
Further specify the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of drunk driving warning device, comprise alcohol gas sensor IC 1, TWH8778 high-power switch device IC2 and single chip machine controlling circuit IC3, voltage output by AV220V connects capacitor C 1, one end shunt resistance R1 of capacitor C 1, other end series diode D1, the mouth parallel capacitance C2 of diode D1, diode DW, resistance R 2, after the capacitor C 3, output connects 7805 constant voltage power suspply IC5,7805 constant voltage power suspply IC5 output connects QM-NJ9 alcohol gas sensor IC 1 and TWH8778 high-power switch device IC2, when detecting the alcohol smell, resistance decreasing between QM-NJ9 alcohol gas sensor IC 1 in-to-in A-B then, the sliding end current potential of potential device W raises, when this current potential is elevated to 1.6V, TWH8778 high-power switch device IC2 connects, be input to the 38th pin I/O end of single chip machine controlling circuit IC3 through resistance 1R1, after single chip machine controlling circuit IC3 internal processes calculation process, divide three tunnel outputs, first via output is sent the sound that ticks by the low level signal of the 1st pin output of single chip machine controlling circuit IC3 through resistance 1R3 promotion loud speaker DBB, reminds the drunk driver please not drive; The low level signal of the 24th pin output of secondary route single chip machine controlling circuit IC3 makes aerotron T1 conducting through resistance 1R2, the relay J adhesive, and switch J-1 closure stops automotive engine and starts operation, makes automobile flameout; Third Road is formed datel circuit by the 8th, 27,28,26 pin and the GSM transmitting-receiving trigger module IC4 of single chip machine controlling circuit IC3, drives GSM transmitting-receiving trigger module IC4 by single chip machine controlling circuit IC3 internal processes control output and sends alarm message to the personnel of appointment.
More than show and described groundwork of the present utility model and principal character and advantage thereof; the technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the explanation just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
