Abstract

This application relates to a high-speed communication synchronization system and data distribution method. The system includes a main control module and several sets of drive boards, each set of drive boards corresponding to printheads with synchronous movement. The main control module separates the signal to be transmitted into a printing data signal and a synchronization signal. The main control module establishes a communication connection with each drive board via an Ethernet communication link to broadcast the printing data signal to the drive boards. The main control module also establishes a communication connection with each set of drive boards via an optical fiber communication link to send the synchronization signal. The synchronization signal is a digital signal. Each set of drive boards is configured in a cascaded topology, and adjacent drive boards are connected via cable communication links. The synchronization signal is transmitted sequentially between the cascaded drive boards via the cable communication links, and adjacent drive boards compensate for the delay of the synchronization signal based on a preset delay time. This application has the advantage of realizing high-precision real-time collaborative operation of large-scale printhead arrays.
