Underwater Non-contact Energy Transmission And Data Transmission System

The sea area accounts for about 3/4 of the Earth's surface area,human activity area is probably only in the shallow sea area,the depths of the ocean 95% of the region for us are unknown world.With the land resources exploration gradually become saturated,but also because the ocean is extremely rich in natural resources,human resources exploration to maritime areas to enter.As a large country,China's marine technology and equipment,the speed of progress can be said to be by leaps and bounds,marine resources are increasingly showing its important strategic significance.In view of the practical requirements of the data of underwater equipment and data collection equipment,this paper proposes and implements a method of underwater non-contact power transmission using electromagnetic induction principle and wireless network technology.And data transmission systems.This system takes the high frequency inversion principle as the core,takes the electromagnetic coupler as the carrier,uses the WIFI wireless communication network as the transmission medium,realizes the wireless transmission and reception of electric energy and data.The experimental results show that the advantages of the system are obvious.The cost of the docking installation is simple,high-efficient and low-cost.The long-life safety of the system can be installed and removed at any time and anywhere.Hydrological environment,reliable work for the underwater equipment to provide sufficient power to monitor the data received feedback to the computer display,in the marine area has a wide range of practical applications.In this paper,the overall design of the system,the hardware system design and implementation,coupler design,software system design and implementation and system transfer in four parts to fully introduce the underwater non-contact power transmission and data transmission system.The whole system can be divided into power supply cavity and equipment cavity two parts.The power supply cavity is responsible for converting the direct current into alternating current with a fixed frequency of 140 KHz.Both of the two cavities are encapsulated with a coupler coil,which transmits alternating current by electromagnetic coupling principle.The device cavity rectifies the alternating current into DC power to supply power to the underwater equipment.The power supply cavity and the device cavity also enclose a pair of WIFI modules,on the one hand the wireless transmission equipment network data,on the other hand wireless transmission two cavity voltage current temperature numerical value,finally together in power supply cavity connection computer displays these Network data.The system through the actual test,the set of underwater non-contact power transmission and data transmission system can efficiently transmit energy,but also to ensure reliable data transmission,various design indicators have been reached.
