A circuit comprises an alcohol gas sensor, a triode, an electronic switching integrated circuit, a language integrated circuit and other elements, the alarm can detect whether a driver drinks or not, if the alarm detects that the driver drinks, the alarm automatically warns with language to remind of the driver to stop driving to avoid the happening of a traffic accident, and the utility model is inexpensive and practical.
Description
Affiliated technical field
The utility model relates to a kind of language alarm of driving when intoxicated, and belongs to civil electronic testing product field.
Background technology
At present, along with the continuous development of situation, vehicle is more and more, and the traffic hazard that takes place because of driving when intoxicated is also more and more, and it is very dangerous to drive when intoxicated.
Summary of the invention
Whether the purpose of this utility model provides a kind of language alarm of driving when intoxicated, can detect the motorist automatically and drink, as detect the motorist and drink, uses language alarm automatically, reminds the motorist to stop to drive.
The purpose of this utility model is achieved in that circuit is by alcohol gas sensor. triode. and the electronic switch integrated circuit. components and parts such as language integrated circuit are formed, direct supply is directly powered to the electronic switch integrated circuit, and by the resistance step-down. the voltage stabilizing diode voltage stabilizing is to alcohol gas sensor and the power supply of electronic switch integrated circuit, the alcohol gas sensor output terminal connects the base stage of triode by resistance, the emitter of this triode connects the negative pole of direct power supply by resistance, the collector of this triode connects the positive pole of direct supply by resistance, the base stage of the output termination triode of language integrated circuit, the emitter of this triode connects the negative pole of direct supply, connect loudspeaker between the collector of this triode and the positive pole of DC circuit, it is characterized in that: 5 pin of the emitter of triode and electronic switch integrated circuit link to each other, 5 pin of electronic switch integrated circuit connect the negative pole of direct supply by electric capacity, and 2 pin of electronic switch integrated circuit link to each other by the power input of resistance with the language integrated circuit.Alcohol gas sensor CM900 model, electronic switch integrated circuit TWH8778 model, burning forms language in the language integrated circuit through electronic equipment, the circuit elements device welds in the circuit board according to the annexation of circuit theory, and be placed in the suitable plastic shell dc power plug automobile-used 12V attaching plug of standard.
Advantage and good effect that the utility model had are: the person stops to drive the generation that avoids traffic accident, inexpensive practicality to remind the driver from drunk driving automatically.
