Intelligent acousto-optic warning system device of automobile whistle

Abstract

The invention discloses an intelligent acousto-optic warning system device of automobile whistle, wherein the intelligent acousto-optic warning system device comprises a power supply converting module, a signal collecting module, an intelligent processing module, a PWM (Pulse-Width Modulation) driving module, a light control module and a horn turn-on judging module, the internal digital-to-analog converter interface, the PWM output interface, the light control output interface and the I / O interface of the intelligent processing module are sequentially connected with the signal collecting module, the PWM driving module, the light control module and the horn turn-on judging module through data wires, and the intelligent processing module is also connected with the power supply converting module; and the intelligent processing module further comprises a microprocessing chip. By means of the mode, the intelligent acousto-optic warning system device of automobile whistle disclosed by the invention can automatically select the horn music volume or utilize a light warning mode according to the automobile state and the peripheral environment when an automobile driver presses the horn so as to reduce the noise pollution caused by the whistle warning, and the device has few modules and a relatively reasonable structure.

Description

Technical field [0001] The invention relates to the technical field of automobile electronics, in particular to an intelligent sound and light warning system device for automobile whistle. Background technique [0002] With the continuous improvement of my country's national economy, automobiles have become more and more popular. While automobiles have brought many conveniences to people's life and travel, the noise pollution generated by car horns has become more and more serious. In order to achieve a warning effect, the car horn will emit a high volume as long as the horn is pressed. During the day on a quiet residential road, vehicles will generally travel at a speed of about 20 kilometers. The noise generated by the car during driving is very small. If there are people on the road ahead, you will generally not notice that there is a vehicle approaching behind you. If the driver presses the horn to remind people in front of him in good faith, the sudden harsh sound of the ho...

Problems solved by technology

Although this technical solution can automatically adjust the volume of the speaker according to the surrounding environment of the car, it only collects the external environment of the car and ignores the state of the car itself, making its technical speaker volume adjustment scheme unscientific; its technology requires the user to determine the default output volume The size makes its technology inconvenient to use; its technology does not make full use of the resources of existing controllers, and there are too many circuit design modules, which makes its technology economical and reliable.
