bile working base station 1 used for supplying energy and sending and receiving data; an unmanned submersible 2 group used for un- derwater continucus observation; and a water surface comprehensive data console 3 used for realizing transmission of control signals 5 and receiving of returned information.

The intelligent control system equipment 21 com- prises a watertight control cabinet and an intelligent controller; the maritime information detection and collection equipment 22 comprises a temperature sensor, a salinity sensor, a sea magnetom- eter, a chemical sensor and other equipment; the underwater navi- gation and positioning equipment 23 comprises inertial navigation equipment, a magnetic compass, long and short baselines, a fiber optic gyroscope and a Doppler log; the underwater sound communica- tion system 24 comprises underwater sound communication equipment located on the submersible 2 and a water surface deck unit located on the base station; the water surface communication system 25 comprises a GPS terminal position indicator, a Beidou terminal po- sition indicator, radio and WIFI; the propelling system 26 com- prises a propeller thrustor, rudders and the like; and the energy system 27 comprises an electromagnetic receiving coil, a recharge- able battery or the like.
A mother ship carries the underwater network continuous ob- servation system to a target area in a sea; and a deck crane re- leases the maritime mobile working base station 1 and the submers- ible 2 in the sea respectively. An implementation is divided into three parts.
First: an implementation mode of the maritime mobile working base station 1. The maritime mobile working base station 1 works and floats on the sea level; and the equipment of the solar power generation device 11 can convert solar power into electric energy which is stored in the storage battery pack. A part of the elec- tric energy is supplied to an energy power system of the maritime mobile working base station 1, and the other part is supplied to an energy power system of the submersible 2. Designed with neutral buoyancy, the maritime mobile working base station 1 remains at a certain position on the sea level by the power positioning system 13 in work; and in case of a dangerous sea state, the base station submerges by the power positioning system 13 and keeps a certain depth in the sea. The power positioning system 13 realizes sub- mergence of the maritime mobile working base station 1 in the fol- lowing principle; and the power controller can judge situations of maritime winds and waves {such as a maximum inclination angle and a sea level wind speed of the maritime mobile working base station 1) according to the inclinometer, gyrocompass and aerovane and can control the rotation thruster to make the maritime mobile working base station 1 submerge.
Second: an implementation mode of the submersible 2 group.
The submersible 2 group carries out an autonomous underwater ob- servation operation in the sea according to task assignment. When energy supply is needed, the submersible 2 returns to a place near the sea level on which the maritime mobile working base station 1 is located. Within a certain distance, the operation is conducted by electromagnetic coupling generated between the electromagnetic transmitting coil located on the maritime mobile base station and the electromagnetic receiving coil located on the submersible 2.
An electromagnetic field is formed by alternating currents in the electromagnetic transmitting coil; electromagnetic induction is generated by the electromagnetic receiving coil located within an irradiation scope of the magnetic field; and currents are generat- ed to charge the battery.
Third: an implementation mode of information transmission. In an underwater operation, information such as positions, postures and situations are transmitted by the underwater sound communica- tion systems 24 in the submersible 2 group, group collaborative operations are conducted and an underwater network observation system is formed; in the underwater operation, the submersible 2 group transmits information such as the positions, postures and situations in real time to the maritime mobile working base sta- tion 1 by the underwater sound communication systems 24 so as to ensure a safe operation; when the submersible 2 floats to a place near the sea level where the maritime mobile working base station 1 is located, the water surface communication system 25 is used to transmit detection data or the like to the maritime mobile working base station 1; and the maritime mobile working base stationl can use the wireless data transmission system 14 to transmit the data information to the water surface comprehensive data console 3 lo- cated on the mother ship or on a shore base.
Working principles and working processes of the underwater network continuous observation system:
Working principles: the underwater network continuous obser- vation system is mainly applied to long-time and long-scope mari- time information gathering of the submersible 2 group. The under- water network continuous observation system is established by a solar power generation technologies, a wireless charging technolo- gy, a computer technology, a motion control technology, an under- water sound communication technology, a wireless information transmission technology, a marine dynamic positioning technology, an underwater navigation and positioning technology, a network technology and the like. The submersible 2 group is charged by the wireless charging technology, so that continuous operations are realized. The wireless information transmission technology is used for information interactions of the submersibles 2 and the base station thereof, so that long-time and large-scope continuous ob-
servation of the submersible 2 group is realized.
According to FIG. 3, the block diagram of an underwater net- work continuous observation method with use of the renewable ener- gy, working processes of the underwater network continuous obser- vation system are as follows: the mother ship carries the underwa- ter network continuous observation system to the target area in the sea; and the deck crane releases the maritime mobile working base station 1 and the submersible 2 group in the sea respective- ly. The maritime mobile working base station 1 is located in the designated area of the sea level in operations by the power posi- tioning system 13 and stores the electric energy by the solar pow- er generation device 11. The submersible 2 group conducts the ob- servation operation according to a preset target. The submersibles carry the sensors, can conduct the operations according to task assignment, make mutual communications and make basic decisions without manual instructions, so that marine elements such as ma- rine temperature, salinity and chemical pollution sources can be sampled, submarine topographies are observed and drawn and the ma- rine environment is closely observed and monitored. When the sub- mersible 2 needs supply of the electric energy, the submersible returns to the place near the sea level on which the maritime mo- bile working base station 1 is located, uses the energy system 27 to charge the self-charging battery and transmits the observation data to the maritime mobile working base station 1 by the wireless communication equipment. The maritime mobile working base station 1 located on the sea level uses the wireless communication equip- ment to transmit the detection data of the submersible 2 to the water surface comprehensive data console 3 located on the mother ship or on a shore base, for later analysis and use. The steps are circulated till continuous operations in the designated sea area or within a period are completed. After the operations or during system maintenance, crane equipment on the mother ship is used to recycle the maritime mobile working base station 1 and the sub- mersible 2 group.
