Synchronization method and device of high-speed industrial communication system, network equipment and storage medium

The embodiment of the invention discloses a synchronization method and device for a high-speed industrial communication system, network equipment and a storage medium. The high-speed industrial communication system comprises control equipment and terminal node equipment, the control equipment broadcasts a frame header synchronization pilot signal, and the frame header synchronization pilot signalcomprises at least one synchronization OFDM symbol. The method comprises the following steps: extracting at least one target synchronization pilot symbol according to a transmission mode; performing correlation operation on the at least one target synchronization pilot symbol; and determining a signal initial moment according to the correlation operation. According to the technical scheme, the precision of high-speed industrial control synchronization can be improved. According to the high-speed industrial communication system and method, the problems that a traditional industrial field bus islow in bandwidth, cannot
