Distributed underwater low-light monitoring system

Abstract

The invention discloses a distributed underwater low-light monitoring system which aims at implementing the multi-angle and large-range wireless video monitoring of the underwater fixed area. More than two underwater low-light imaging devices and more than two video signal coders are sealed in an underwater sealing cabin body; a power supply module and a water wireless communication module are sealed in a moored buoy; the power supply module is used for supplying power for the water wireless communication module, the underwater low-light imaging devices and the video signal coders; video signals of the underwater sealing cabin body are processed through the video signal coders to be transmitted to the water wireless communication module through an underwater transmission cable and transmitted to a shore wireless communication module through a wireless communication protocol; the data are processed through a processor to be transmitted to a central control board to be displayed; control signals are transmitted to the power supply module through the central control board in a wireless communication mode to implement the control on the switch control of the power supply module. According to the distributed underwater low-light monitoring system, the multi-angle and large-range wireless video monitoring of the underwater fixed area can be achieved.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a distributed underwater low-light monitoring system. Background technique [0002] With the development of oceans and rivers, the scale of underwater engineering is getting bigger and bigger, especially in aquatic product cultivation, underwater monitoring has become the eye of the development of waters, and its application has become more and more extensive. At present, there are mainly two kinds of underwater monitoring methods that are often used. One is that divers carry camera equipment to shoot underwater conditions. This method needs to be completed by well-trained divers. The water depth can only be within 50 meters, so the cost is high, and It cannot reflect the real situation immediately. The second is to put the sealed camera underwater, and its signal is transmitted to the display through the cable for observation. The transmission distance of this method is limited, and each c...

At present, there are mainly two kinds of underwater monitoring methods that are often used. One is that divers carry camera equipment to photograph the underwater situation. This method requires well-trained divers to complete, and the water depth can only be within 50 meters, so the cost is high, and It cannot reflect the real situation immediately. The second is to put the sealed camera underwater, and its signal is transmitted to the monitor through the cable for observation. The transmission distance of this method is limited, and each camera occupies a cable. When the number of cameras Difficult to implement in many cases

[0003] Chinese patent 200810011543.8 discloses "a video transmission and monitoring system for remote-controlled underwater robots", which can realize underwater monitoring through multiple cameras, and transmit data through optical fiber communication. The wiring is cumbersome and difficult to use flexibly.

Chinese patent 200810032336.0 discloses "a high-mobility wireless network video surveillance system and its control method", which can realize wireless video transmission but is difficult to use underwater

Chinese patent 200820141755.X discloses the "underwater video surveillance system through wireless transmission". The work of its underwater camera depends on the cruise ship on the water surface, and it is limited when used in large quantities, and it is difficult to monitor fixed points for a long time
