Embodiment Construction

[0025] In the prior art, the interaction between the MCU and the time base generator is usually used to generate different timing moments, and at different timing moments corresponding to PWM waves with different duty ratios, high and low level changes are generated, thereby generating PWM waves with different duty ratios. When the duty cycle of the PWM wave is constant, the number of interactions between the MCU and the time base generator is less, and only the initialization configuration needs to be completed. However, in the field of scene lighting, when the scene is switched, the duty cycle of the PWM wave is dynamically adjusted in real time according to the user's experience. At this time, the MCU needs to dynamically provide different dimming curves, and frequently communicate with the time base generator Interactively adjust the duty cycle of the PWM wave dynamically, which requires high computing performance of the MCU.

Abstract

An intelligent lighting control system, a control method, and an intelligent lighting system, the intelligent lighting control system comprising: a main controller, a PWM data buffer controller, and a time base generator, wherein: the main controller is adapted to receive user input the dimming instruction, generate the corresponding target pulse width adjustment parameter according to the dimming instruction, send the target pulse width adjustment parameter to the PWM data buffer controller, and send the PWM wave to the PWM data buffer controller Generate instructions; the PWM data buffer controller is adapted to store the target pulse width adjustment parameters, and when receiving the PWM wave generation instructions, control the time base generator to generate and adjust the target pulse width parameters Corresponding PWM wave; the time base generator is adapted to generate a PWM wave corresponding to the target pulse width adjustment parameter, and input the generated PWM wave to the LED driving circuit. The above-mentioned solution can reduce the demand on the computing performance of the MCU when the LED lighting equipment performs dimming.

Description

technical field [0001] The invention relates to the field of intelligent lighting, in particular to an intelligent lighting control system, a control method and an intelligent lighting system. Background technique [0002] Compared with traditional lighting equipment such as incandescent lamps and fluorescent lamps, Light Emitting Diode (LED) lighting technology has obvious advantages in energy saving, environmental protection, lifespan, color, volume, weight, etc., and has become the mainstream technology in the current lighting field. . [0003] In the field of intelligent lighting, according to the characteristics of LED lighting that can produce the three primary colors of red, green and blue, through the use of digital control technology, LED lighting can achieve colorful lighting requirements. LED lighting digital control technology usually adopts Pulse Width Modulation (PWM) method. For the three primary colors of cold light, warm light, and red-green-blue (Red-Green...
