Shore-based power supply multi-point monitoring deep sea camera system

Abstract

The invention relates to a shore-based power supply multi-point monitoring deep sea camera system comprising a shore-based power supply, a power supply converter, a power supply module, n sets of deep sea cameras with deep sea illuminating lamps (the n is equal to 1-20), a video collecting unit, a signal processing unit and a shore-based server. The shore-based power supply is used for converting the commercial power to about 2KV direct-current power, electric energy is transmitted to the power supply converter at the bottom of the sea through a deep sea cable, the power supply converter converts the 2KV direct-current power to 400 V direct-current power, and then the 400 V direct-current power supplies working voltage for each unit of the system through the power supply module. Each deep sea camera with the deep sea illuminating lamp is provided with number set of respective monitoring zone, the video collecting unit packs and compresses the collected video signals of the deep sea cameras and transmits the video signals to the signal processing unit which coverts the digital video signals to optical signals, and then the optical signals are transmitted to the shore-based server through an optical fiber. The deep sea camera system has reliable running and can realize multi-point, real-time and long-time camera video monitoring on the bottom of the sea.

Description

technical field [0001] The invention relates to a shore-based power supply multi-point monitoring deep-sea camera system, which is particularly suitable for real-time multi-point, continuous and long-term video monitoring in the field of deep sea bottom. technical background [0002] At present, video monitoring has become a very important means in the research work of deep-sea submarine exploration, and research on related technologies such as deep-sea photography has been carried out abroad. For a long time, domestic deep-sea subsea video surveillance methods still mainly rely on traditional methods such as camera powered by a self-provided battery. The self-contained battery-powered camera system of the bracket can only conduct video surveillance on the seabed in a small range for a short time, and cannot realize long-term video surveillance on the seabed, and the monitoring range is limited. It is more difficult to realize multi-point monitoring, and the working cycle of...

Problems solved by technology

The self-contained battery-powered camera system of the bracket can only conduct video surveillance on the seabed in a small range for a short time, and cannot realize long-term video surveillance on the seabed, and the monitoring range is limited. It is more difficult to realize multi-point monitoring, and the working cycle of the system is short. The cost of repeated deployment is relatively high, and maintenance is difficult
