Problems solved by technology
However, the existing large-scale scene control system does not consider the delay generated when the internal control system of the GPS module processes the clock signal in the process of synchronous control
The clock signal received by different control systems will be different. The clock signal is the synchronization signal of the entire large-scale scene control system, which will cause different scene control modules to output LED control signals without complete synchronization.
In the scene control system with high real-time requirements and high synchronization requirements, the control picture will be unstable.

Description
technical field [0001] The invention relates to LED control technology, in particular to a real-time synchronous large-scale scene control system and an implementation method thereof. Background technique [0002] The clock synchronization problem of the control system has always been a difficult problem for the scene control system. Due to the clock operation error of the CPU, each control system has a clock asynchronous problem during operation, especially in a large-scale scene control system. For different control modules Precise clock synchronization is required. In the large-scale scene control system currently on the market, GPS is used to control multiple groups of LED lights synchronously. However, the existing large-scale scene control system does not consider the delay generated when the internal control system of the GPS module processes the clock signal in the process of synchronous control. The clock signal received by different control systems will be differ...
