Problems solved by technology

Underwater communication mainly uses sound, electromagnetic waves, and light. However, the underwater acoustic channel has disadvantages such as long transmission delay, low transmission rate, limited available bandwidth, high power consumption, large size, and poor security; electromagnetic waves are used for underwater wireless communications. For communication, since electromagnetic waves are transverse waves and water is a good conductor, the skin effect will seriously affect the transmission of electromagnetic waves in water

Abstract

The invention discloses an underwater communication system, which comprises a sender and a receiver, wherein the sender consists of a first power module, a sensor signal detection module, an MCU maincontrol module and a light emission module; the sensor signal detection module is connected with a monitoring unit of the MCU main control module through a serial port; the light emission module is connected with a data output/input unit of the MCU main control module through a serial port; the receiver consists of a second power module, a signal processing module, a light receiving module and a decoding modulator; the output end of the light receiving module is connected with the input end of the signal processing module; and the output end of the signal processing module is connected with the input end of the decoding modulator. The underwater communication system overcomes the shortcomings that an acoustic wireless scheme is extremely narrow in bandwidth and attenuation of electromagnetic waves of relevant bands for ground bandwidth wireless transmission in water is too large.

Description

technical field [0001] The invention relates to the field of underwater communication, in particular to an underwater wireless LED light source communication system. Background technique [0002] Underwater wireless communication is a key technology for the development of ocean observation systems. With the help of ocean observation systems, data related to oceanography can be collected, environmental pollution can be monitored, climate changes can be caused by abnormal seismic and volcanic activities on the seabed, submarine targets can be detected, and long-distance image transmission can be carried out. Underwater wireless communication also plays a vital role in the military, and underwater wireless communication is also a key technology for underwater sensor networks. Underwater communication mainly uses sound, electromagnetic waves, and light. However, the underwater acoustic channel has disadvantages such as long transmission delay, low transmission rate, limited avai...
