Embodiment Construction

[0022] The present invention avoids the drawbacks that satellite monitoring is easily affected by weather factors such as clouds through the monitoring method of ships, vehicles and boats, and uses a hybrid wireless solution for data transmission to solve the shortcomings of a single network transmission mode; the existing 3G network has incomplete coverage and insufficient signal bandwidth. The investment of setting up 3G base stations is high and the income is low; as a short-distance transmission method, WiFi needs to build a large number of network access points for signal coverage, and the construction is difficult; the full water coverage of WiMAX signals also requires the establishment of a large number of new base stations, and the return on investment Small; use the existing network resources, combined with a variety of communication methods, to establish a hybrid wireless communication mode suitable for wide waters.

Abstract

The invention discloses a wireless video monitoring system based on a wide water domain. A ship, vehicle and boat hybrid monitoring manner is adopted to establish a monitoring system, a wireless-based network-carrying system is constructed for a ship-vehicle-boat monitoring system, wireless network coverage is carried out by a 3G (The 3rd Generation Telecommunication)+WiMAX (Worldwide Interoperability for Microwave Access)+WiFi (Wireless Fidelity) hybrid architecture mode, servers are erected on a boat, a vehicle and a boat for transmitting and processing videos, and video data acquired by the ship, the vehicle and the boat are transmitted to a monitoring center through the network-carrying system. The monitoring system based on the wide water domain, provided by the invention, has the advantages of good coverage type, flexibility in detection, no influence from weather environment, and the like, can better avoid the defect brought by traditional satellites, can be used for monitoring the wide water domain in real time, has a aerial panorama with the formation time reduced from traditional 3-7 days to about 1-2 days, and can work under weather conditions such as rain, snow, fog and the like that the traditional satellites can not form an image and give a corresponding result image.

Description

technical field [0001] The invention belongs to the field of network communication, and is applied to wireless video surveillance in wide waters, such as Taihu Lake Basin, Poyang Lake Basin, Dongting Lake Basin, etc., to ensure 24-hour remote real-time monitoring and detection of the water surface, and is a wireless video surveillance system based on wide waters. Video surveillance system. Background technique [0002] At present, due to the illegal discharge of industrial and domestic sewage in my country's lake areas and river basins, water pollution, especially eutrophication, is particularly serious. Especially in the Taihu Lake Basin, a sudden blue-green algae outbreak in 2007 caused major damage to people's lives and property. Loss; Although the pollution control of various water areas is gradually increasing, the phenomenon of illegal discharge of sewage is becoming more and more serious, and the lack of monitoring functions is quite serious. It often takes 3 to 5 days...
