Control system with sound source tracking head lamp

Abstract

The invention discloses a control system with a sound source tracking head lamp. The control system is characterized by comprising an MCU module, a photosensitive sensing module, an illumination driving module, a steering engine control module, a stepping motor module, a microphone array module, a button switch module, an analog quantity sampling module, a buzzer module, a photovoltaic charging module and a lithium battery module, wherein the microphone array module is connected with the analog quantity sampling module; and the MCU module is connected with the photosensitive sensing module, the illumination driving module, the steering engine control module, the stepping motor module, the microphone array module, the button switch module, the buzzer module and the photovoltaic charging module. The control system of the invention has the following advantages that the brightness of a surrounding environment can be detected at night, then the brightness of an LED lamp is adjusted according to the brightness of the surrounding environment, the range of collected sound waves is large, the collection distance of the sound waves is long, and meanwhile, due to the fact that a microphone array is installed, the sound position can be judged according to time difference of sound transmission and sound wave intensity, and sound source positioning can be accurately conducted.

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
