Benefits of technology
This technology improves on existing methods by eliminating extra cables that are necessary when communications between different devices occur over land or water (LF). It also allows multiplexed data streams with improved efficiency compared to traditional wired connections. Additionally, this system uses lights made from specific material instead of bulky weights attached at one end to improve its effectiveness against gravity waves caused by sea currents during use. Overall, these technical improvements make oceanographic operations more efficient while minimizing costs associated therewith.
Problems solved by technology
This patents discusses various aspects related to electronic devices called radiocommunicators/underwatersensibeters (RNAs) deployed during oil exploration operations. These include challenges associated with transmitting signals wirelessly between undersea stations without being affected by external factors like sea currents or changes in temperature. Additionally, they have limitations in terms of their own strength and stability caused by environmental conditions including salt spray flooding and radiation exposure. Overall, the challenge presented in the design problem addressed by the patented solution involves improving the reliability and effectiveness of electric vehicle communication technologies while minimizing costs and simplifying installation procedures.

Embodiment Construction
[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and through specific embodiments.
[0025] Such as Figure 1-3 As shown, the present invention includes a carrier transmitting end, a carrier receiving end and a neutral buoyancy cable. The carrier transmitting end transmits a carrier signal, which is transmitted to the carrier receiving end through a neutral buoyancy cable for receiving; the carrier transmitting end includes a host computer string Line interface, main control chip, power line carrier modulation module, transmission coupling circuit and coupling transformer. During the transmission process, the signal enters the power line carrier modulation module for modulation after passing through the host computer serial After the transmission coupling circuit is processed, it finally enters the neutral buoyancy cable through the coupling transformer; the carrier receiving end includes the host computer serial interfa

The invention discloses a power line carrier communication apparatus used for overocean communication. The apparatus comprises a carrier transmitting terminal, a carrier receiving terminal and a neutral buoyancy cable. The carrier transmitting terminal emits a carrier signal and the carrier signal is transmitted to the carrier receiving terminal through the neutral buoyancy cable so as to be received. The carrier transmitting terminal comprises an upper computer serial interface, a master control chip, a power line carrier modulation module, an emission coupling circuit and a coupling transformer. The carrier receiving terminal comprises the upper computer serial interface, the master control chip, the power line carrier demodulation module, a receiving coupling circuit and a decoupling transformer. The neutral buoyancy cable is a light-buoyancy-material counter-weight coaxial cable. In the invention, during communication, a special communication cable is not added so that engineering cost and construction difficulty are greatly reduced; multichannel coupling is used so as to reach a high parallel communication rate; independent coupling and decoupling circuits of each channel guarantee effective modulation and demodulation of each independent channel carrier wave; and the special coaxial cable is used so that communication reliability is increased.
