Abstract

The invention relates to a system and method for automatically adjusting sound volume of a car horn, capable of actively and automatically adjusting horning sound volume according to different environments. By the adoption of the system and method, the problem that an automatic sound volume adjustment device adjusts sound volume unscientifically in the prior art can be solved. According to the key points of the technical scheme of the invention, the system for automatically adjusting sound volume of a car horn comprises a horning button, a car horn and an audio power amplifier, wherein the car horn is electrically connected with the audio power amplifier; the system for automatically adjusting sound volume of a car horn also comprises a control chip and a plurality of environment sensors, wherein the environment sensors are connected with the control chip electrically through an analog-to-digital converter, the output port of the control chip is connected with the signal input end of the audio power amplifier electrically through the analog-to-digital converter, and the horning button is connected with the control chip electrically. The system and method can be used for actively and automatically adjusting horning sound volume according to different environments and realizing sound volume linear adjustment during the process of continues horning.

Description

technical field [0001] The invention relates to a car horn, in particular to a car horn volume automatic adjustment system and a method thereof which can actively adjust the volume of the horn for warning according to different environments. Background technique [0002] As we all know, traffic accidents are a huge threat to the safety of people's lives and property. Timely whistle warnings during driving can greatly reduce the probability of traffic accidents. However, in the current horn system, the volume of the horns is the same. The weather of heavy rain or typhoon is inevitable. At this time, the transmission of the warning sound of the horn will be hindered to a certain extent. Compared with sunny days, the transmission is not very clear, which greatly affects the warning effect; The warning effect of the siren warning will be relatively poor, and the volume of the horn will not change, even if the driver repeatedly whistles the warning, once the surrounding environm...
