System for automatically adjusting whistling volume of freight transport vehicle

Abstract

The invention discloses a system for automatically adjusting the whistling volume of a freight transport vehicle. The system comprises a whistling button, an automobile horn, an audio power amplifier, a control chip and at least one environmental sensor. The automobile horn is electrically connected with the audio power amplifier. The environmental sensor is electrically connected to the control chip via an analog-to-digital converter. The output port of the control chip is electrically connected to a signal input end of the audio power amplifier through a digital-to-analog converter. The whistling button is electrically connected with the control chip. The environmental sensor is a distance sensor, and the control chip is electrically connected with a GPS module. The system has the advantages of controlling the volume of the horn by measuring the distance and the time, being very suitable for the freight transport vehicle, greatly reducing the pollution of the noise, enhancing the living quality of residents, and having wide application prospect.

Description

technical field [0001] The invention belongs to the field of environmental protection transportation, and in particular relates to a system for automatically adjusting the volume of the whistle of a cargo transportation vehicle. Background technique [0002] With the rapid development of China's economy, the automobile industry has become more and more prosperous, and the number of automobiles in China's cities has been at the forefront of the world, but the accompanying pollution problems have become more and more serious, such as air pollution, noise pollution, etc. For noise Pollution, especially the pollution caused by car horns and horns, is one of the best pollution. Many countries have banned cars from honking, but for countries and regions that have not yet adopted the ban on horns, the pollution caused by horns is still urgent. One of the troubles that needs to be solved, especially for the residents living around the main road, at night is the time when goods and v...

Problems solved by technology

[0002] With the rapid development of China's economy, the automobile industry has become more and more prosperous, and the number of automobiles in China's cities has been at the forefront of the world, but the accompanying pollution problems have become more and more serious, such as air pollution, noise pollution, etc. For noise Pollution, especially the pollution caused by car horns and horns, is one of the best pollution. Many countries have banned cars from honking, but for countries and regions that have not yet adopted the ban on horns, the pollution caused by horns is still urgent. One of the troubles that needs to be solved, especially for the residents living around the main road, at night is the time when goods and vehicles frequently come in and out, and it is also the rest time, so it has caused great trouble for these residents to rest, and they have been affected by the noise for a long time. Interference, and even mental breakdown, so the market urgently needs a system that can adjust the volume of the speaker according to the specific environment

[0003] The patent application number CN201110092184.5 has proposed an automatic condition system that automatically adjusts the volume of the whistle horn according to the surrounding environmental conditions, but it is more to solve the problem of adjusting to a larger volume or a smaller volume due to weather conditions or at night. , not specifically for the volume adjustment of the special vehicle of the truck, so it is not particularly suitable for the noise control of the cargo transport vehicle, and further improvement is needed on this basis
