Abstract

The invention relates to an auxiliary synchronization LED control device and an LED light control system. The LED control device comprises a satellite navigation signal receiving module, a frequency multiplier, a timestamp module and a first LED controller. The satellite navigation signal receiving module is used for generating a high-precision pulse signal and time information; the frequency multiplier is used for multiplying the frequency of the high-precision pulse signal to obtain a frequency-multiplied pulse signal; the timestamp module is used for adding time information into the frequency multiplication pulse signal to obtain a reference clock signal; the first LED controller comprises a communication interface module and a driving data conversion module, and the communication interface module receives and sends a reference clock signal and also receives picture data; and the driving data conversion module is used for converting and processing the picture data corresponding to the playing time information according to the reference clock signal and generating an LED driving signal for the LED driving circuit to work. According to the scheme, microsecond-level time synchronization precision can be provided, and the device is arranged outside a building, so that the problem of difficult signal receiving is solved.

Description

technical field [0001] The invention relates to the field of LED light control, in particular to an auxiliary synchronization LED control device and an LED light control system. Background technique [0002] Because LED has the characteristics of low energy consumption, high brightness, and high refresh rate, it is widely used in display, lighting, backlight and other fields. In landscape lighting and urban lighting, LED can bring comfortable visual perception and good artistic beauty, and has developed rapidly in recent years. [0003] Usually, a city lighting project has a large scale and a wide range of distribution, spanning multiple buildings, and may include tens of thousands of square meters, or even hundreds of thousands of square meters of facades. An LED lighting control system of this scale is generally composed of a host computer and multiple independent LED controllers. The host computer performs time synchronization control on the LED controller and sends pict...
