Bluetooth two-mode intelligent light-sound control system and method

Abstract

The invention discloses a Bluetooth two-mode intelligent light-sound control system and method. The system comprises an AC voltage stabilizing circuit, a DC voltage stabilizing circuit, an MCU (Micro Controller Unit), a driving circuit, a Bluetooth module, a power amplifier circuit, a horn, a light source and a light-sound control APP. The Bluetooth module receives an audio signal transmitted by a mobile terminal and the light-sound control APP and transmits the audio signal to the MCU; after the MCU decodes the audio signal, the audio signal is transmitted to the power amplifier circuit; after amplification, the audio signal is output to the horn to play; the mobile terminal transmits debugging data and a control signal to the MCU through the light-sound control APP and the Bluetooth module; the MCU outputs a corresponding duty ratio to carry out corresponding dimming, color modulation or RGB (Red Green Blue) modulation and system control on the light source through a multichannel PWM (Pulse Width Modulation) signal according to the debugging data and the control signal. The implementation of the invention has the following beneficial effects that the problems of poor angle, light flashing and power consumption can be improved, the light and the sound are combined, the personalized requirements of users are met, the adjusting way is convenient, and the different experience is brought to the users.

Description

technical field [0001] The invention relates to the field of light and sound control, in particular to a bluetooth dual-mode intelligent light and sound control system and control method. Background technique [0002] As people's requirements for the quality of life are getting higher and higher, modern lighting will pay more attention to energy saving and convenience, as well as the individual needs of human beings, in addition to meeting people's basic life and work and study requirements. Personality, intelligence, safety, and energy-saving lighting will be the general trend of lighting in the future. [0003] There are two traditional dimming methods, one is the adjustment method using infrared remote control, and the other is the adjustment method using wireless remote control. The adjustment method of infrared remote control is limited by the dimming angle and dimming distance. And the lights flicker from time to time, and the adjustment method of the wireless remote ...
