Data concentration system for inner detector of oil-gas pipeline, and timing control method

A data concentration system for an inner detector of an oil-gas pipeline, comprising:

• a multi-channel data receiving module, electrically connected to a plurality of probes of the inner detector and configured to receive detection data acquired by the plurality of probes;
• a data concentration module, electrically connected to the multi-channel data receiving module, and configured to receive the detection data outputted by the multi-channel data receiving module and compress the detection data;
• and
• a data transmission module, electrically connected to the data concentration module and configured to receive compressed detection data from the data concentration module;
• wherein, the multi-channel data receiving module adopts a duplex communication mode, and the multi-channel data receiving module is configured to simultaneously transmit an acquisition instruction to the plurality of probes and receive the detection data acquired by the plurality of probes.
