Switching command is assigned to intellectual status management module in case system, data-interface plate is cut by sleep state or running status
Swap-in enters holding state, can also be switched over from holding state to sleep state or running status；
All modules in running status, ocean seismic exploration haulage cable data-interface plate are in the state worked on power, sea
The streamer data that foreign towing cable is uploaded is incoming after ocean seismic exploration haulage cable data-interface plate of the present invention processing
In MicroTCA case systems, user is managed by core bus interface module from MicroTCA case systems to intellectual status
Module assigns switching command, ocean seismic exploration haulage cable data-interface plate is switched into running status by holding state,
It can be switched over from running status to holding state；
In three kinds of working conditions, with per family can be by the microcontroller chip in Intelligent management module with obtaining the ocean in real time
ID, temperature, voltage x current and the radiating state of seismic exploration towline data interface plate.
