Definitions
- the deep submarine network which is the subject of the invention, comprises main and secondary transport segments, nodes arranged at the points of use and local sensors. It is characterized in that:
- the nodes (11) are energy autonomous switches to which the ends (10) of the transport segments and the local sensors (6) are connected at the bottom.
- the deployment device (14) serves as a structure on which the underwater vehicle can come to dock to operate under the best conditions the connection or disconnection of the local sensors (6).
- New secondary transport segments (15) can also be connected to extend the network.
- the maximum reasonable length envisaged for each segment is of the order of fifty kilometers.
- the mass in the air of the micro-cable used is of the order of 500 kilograms and the maximum tension admissible during its deployment is of the order of 50 kilograms. Due to its high inertia a simple rotating coil without voltage regulator device seems a priori difficult to develop.
- a rotating spool in internal rotation (torpedo or missile type) or outward unwinding (fishing reel type) can circumvent these problems of inertia. This is the first claimed embodiment.
- the supervisory circuit (22) connected to one of the ports (16) of the switch provides a number of programmable functions when it is turned on. One of the functions is to be able to cut the detection of the signal coming from one of the receivers (19). This security function allows the supervisor of the network to prohibit a sensor (6) faulty or poorly programmed to awaken the node and therefore the entire network.
- Figure 5 shows the location of the connectors (7 and 10) located at the periphery of the upper flange of large diameter (26). This arrangement allows the underwater vehicle to access the connectors while minimizing the total volume of the cylindrical enclosure.
- the deployment device (14) is carried by a float (31) whose buoyancy can be adjusted by means of a regulator (32) filled by means of a valve (33) actuated by the underwater vehicle (29). ).
- This arrangement allows the underwater vehicle to balance the weight in the water of the assembly as the deployment of the micro-cable segment (9) according to its limited lifting capabilities.
- the network deployment device (14) includes a micro-cable burying device arranged to the output of the deployment device (14).
