[Abstract]:In recent years, China's maritime industry has been actively innovating in ship supervision, breaking through the previous regulatory model and actively using modern information equipment to carry out innovative mode management. However, maritime safety supervision infrastructure is still very weak. The phenomenon of violating rules and regulations is also common, which causes huge economic loss to the country, and brings serious harm to the safety of people's life and property at the same time. Therefore, in order to strengthen the supervision of waterborne vessels and the application of real-time monitoring, positioning and navigation technology to all kinds of passenger ships, township ferries, this paper implements wireless video surveillance management for tourist ships and transport vessels. The land video surveillance management and the remote dispatch command when the emergency occurs reduces the property loss and guarantees the life safety and provides the powerful support and the safeguard for the water transportation safety. This paper presents a design scheme of maritime wireless monitoring system based on 3G technology, which adopts 3G wireless communication technology and computer network technology, and uses 3G wireless ship monitoring terminal hardware to improve maritime supervision ability. This paper analyzes the advantages of 3G and CCTV monitoring system, and expounds the important role of 3G visual integrated maritime supervision and management system in maritime supervision and management combined with the characteristics of 3G wireless monitoring system. 1. Select the communication mode of remote wireless video image. By analyzing the communication mode of the existing video surveillance system, the remote wireless video image monitoring mode suitable for this system is selected. 2. Select the access mode of the wireless network. According to the communication mode of remote wireless video image, the best wireless network access mode is determined. 3. Select the appropriate video stream encapsulation method. According to the selection of wireless network video image transmission mode, real-time transmission of video stream monitoring image data requirements and video data coding form, combined with the video stream encapsulation method, the real-time monitoring of remote wireless video image is implemented efficiently. And improve the fault tolerance of video stream monitoring image data transmission. 4. Video wireless network transmission optimization. In order to solve the problem of high error code in video surveillance image transmission, an effective solution is put forward to realize the high fault tolerance of video image transmission.
