The automatic distributor in succession of ocean seismic prospecting appearance tow-cable data acquisition node address

The utility model relates to an ocean seismic prospecting equipment technical field especially relates to an ocean seismic prospecting appearance tow-cable data acquisition node address automatic and continuous distributor. Include host computer and the data acquisition node position address allocation board of being in the same place with its passing signal line series connection in proper order, data acquisition node position address allocation board is become by main control chip, memory chip and physical address chipset, said main control chip with memory chip connects, memory chip pass through the I2C BUS with the physical address chip is connected. 1, the position address and physical address one-to-one are preserved in the host computer, if certain one data acquisition node breaks down, can fix a position its position in the tow-cable rapidly. 2, the position address storage is in erasable memory chip, and the position address of data acquisition node can be erased. In data acquisition node mounted position in tow-cable back that changes, the location of can the relocation bit buying an estate.
