A control system for headlights with sound source tracking

Abstract

This application discloses a control system for headlights with sound source tracking, which is characterized in that it includes an MCU module, a photosensitive sensor module, a lighting drive module, a steering gear control module, a stepping motor module, a microphone array module, and a button switch module , an analog sampling module, a buzzer module, a photovoltaic charging module and a lithium battery module; the microphone array module is connected to an analog sampling module, and the MCU module is connected to a photosensitive sensor module, a lighting drive module, a steering gear control module, and a stepper motor module, microphone array module, button switch module, buzzer module and photovoltaic charging module. The invention has the following advantages: the invention can detect the brightness of the surrounding environment at night and then adjust the brightness of the LED light according to the brightness, and the range of sound waves that can be collected is relatively large and the distance is relatively long. The position of the sound can be judged by the time difference and the intensity of the sound wave, which can accurately locate the sound source.

Description

technical field [0001] The invention relates to the technical field of headlamp devices, in particular to a control system for headlamps with sound source tracking. Background technique [0002] The headlights in the existing market need to be manually adjusted every time they are used, and the headlights need to be adjusted multiple times for on and off and brightness adjustment. There is a headlight that automatically adjusts its brightness as the ambient brightness changes. [0003] For example, the patent number is CN201711179409.4, the patent name is a self-induction adjustable headlight, and the patent discloses a self-induction adjustable headlight, and its working principle is as follows: when the self-induction adjustable headlight is working, the user will The light is worn on the head with an elastic band 7 and fixed, and the photoresistor 3 of the exposed light body 2 will change the resistance value according to the ambient illumination, thereby changing the cu...

Problems solved by technology

[0004] As described in the above patent, the invention can adjust the brightness of the headlights according to the brightness of the environment. However, for the field work environment, the field of view at night is narrower than that of the day, and accidents are prone to occur only by relying on the field of view. The field sound transmission at night Farther away, providing a sound source localization function can effectively overcome the shortcomings of people's vision at night, and meet the needs of field working environments
