Description

Illumination and sensor and communication integrated system and device of underwater vehicle

Technical Field

The utility model belongs to the technical field of underwater communication system and device, more specifically relate to illumination and sensor and communication integration system and device of underwater vehicle.

Background

In the modern world, with the continuous exploration of deep sea by human beings and the development and utilization of marine resources, the relationship between human beings and the sea is more and more close. The fields of underwater robots, underwater navigation and diving devices, underwater detectors, underwater naval submarines, underwater sensor networks and the like are developed at a high speed, the existing underwater communication means cannot keep pace with the high-speed development of underwater communication, and a new and efficient underwater communication means is urgently needed to be found.

Currently, underwater acoustic communication is still the main means of underwater communication. The underwater communication by using the acoustic technology is always the main technical direction of people, and has the defect that the underwater communication is easily influenced by various factors such as water quality, water temperature, water pressure and other underwater noises, so that the underwater communication is commonly used for transmitting simple data information such as characters, voice information and the like, is not suitable for the military application field and is easily detected by enemy sonar reconnaissance equipment. Underwater acoustic communication also has the problems of high power requirements, high manufacturing costs, relatively large equipment volume, and low data transmission rates, which make underwater acoustic communication difficult to use in small underwater robots. In a relatively complex underwater communication network, the underwater acoustic communication chain also exhibits a long propagation delay, which affects the use of acoustic technology in special scenes in the underwater part. Regarding underwater electromagnetic wave communication, as a water body is a special communication channel, when electromagnetic waves are transmitted in water, the electromagnetic waves are seriously attenuated, and long-distance transmission is difficult to realize. Compared with other underwater wireless communication technologies, underwater visible light communication has more advantages. Firstly, the disadvantages of small transmission bandwidth, low communication rate, large propagation delay, large volume of equipment system and the like of underwater acoustic communication can be overcome by underwater visible light communication. Meanwhile, the underwater visible light communication can overcome the absorption characteristic of electromagnetic waves in water, reduce the loss of attenuation and realize long-distance transmission. Optical LED underwater communication is an effective way of short-range underwater communication. The underwater monitoring system can replace some communication technologies like acoustics in the current underwater technology in a short distance range, is particularly used in certain specific environments such as shallow sea, coastal areas and inland water areas, is beneficial to overcoming the defects of the communication technologies like acoustics, can be widely applied to the underwater monitoring system, and can be used for reliably monitoring and monitoring data in a limited time and in a low-power-consumption mode on occasions with high conversion rate and large data volume, such as videos and pictures, and the like. The small-size and low-cost components are built, and a densely deployed underwater detection network is easy to build, so that reliable short-distance high-speed data transmission can be performed underwater. However, the underwater visible light communication also has the problem of large attenuation factor transmitted in seawater.

At present, how to overcome the series of defects existing in the traditional underwater acoustic communication, how to overcome the problem that the transmission attenuation factor of the underwater visible light communication in the seawater is large, how to improve the efficiency and reliability of the underwater visible light communication, how to tightly combine the underwater visible light communication with an underwater camera and a sensor, how to further expand the application fields of the underwater visible light communication and the underwater automatic detection, and the problems are solved by people.
