Zusammenfassung:According to the technical scheme, the ship-based multi-channel signal acquisition synchronous control system based on the FPGA comprises M ADC (analog-to-digital converter) chips used for analog-to-digital conversion; the FPGA is used for organizing the plurality of digital intermediate frequency echo signals subjected to analog-to-digital conversion processing into format data required by the optical module and synchronously sending the format data to the optical module; the M ADC chips are used for synchronously outputting the digital intermediate frequency echo signals subjected to analog-to-digital conversion processing according to the pulse per second signals for synchronization so as to complete first synchronization; and the FPGA is used for observing the multi-frame clock signal waveform in the state waveform of the rapid detection output pin of the ADC chip, and if the multi-frame clock signal waveform has time delay, after the output period of the ADC chip is completed, the processed format data r
