The Development Of Monitoring And Alarm System In The Ship Cabin Based On Audio And Video

Marine shipping industry is an old industry. With the continuous development of scienceand technology, Marine power plant mainly rely on manpower to the steam engine and then tothe internal combustion engine, Ship control system developed from manual control to formautomatic control system based on control equipment. In the21st century, Shipbuilding industryelectric degree of automation, performance and technical level has greatly improved, With thecomputer technology and communication technology has become more sophisticated, Led toincreasing development and wide application of computer technology on the ship. The conceptof unmanned engine room of ship is constantly applied to the practice.Audio and video monitoring and alarm has played an important role in many fields such asbuilding, transportation, industrial. In the traditional ship’s audio and video monitoring is limitedto voice acquisition, image monitoring. With the enhancing of ship safety performancerequirements. In this thesis, Marine engine automation cabin as research background. Develop tothe cabin images, audio, acquisition and automatic recognition, remote wireless monitoring,alarm display, PIZ linkage system. In ship engine room under the normal condition, the influenceof the light is relatively stable. In the event of a fire, a large number of important parameters suchas smoke, engine room equipment abnormal situations, Through image recognition, identifyanomalies and the location of the exception, Connected to the alarm data acquisition platform,determine the exception information, quickly track and locate the cabin abnormal area, and sendout alarm signal. Through the cabin the acquisition of sound, Understand the cabin for live,When an exception occurs in a timely manner and cabin management personnel to communicate.In this paper, the development of audio and video monitoring technology in recent years areintroduced, Describe the characteristics of the monitoring system for each stage of development,The application status of the ship are described, and analyzes the future trend of development,puts forward the overall architecture of this system, and proposed scheme of track of anomalies,Design for the development of the whole monitoring system. The automation engine room audioand video monitoring system mainly by the underlying monitoring equipment, networktransmission, wireless bridge, the monitoring center, center service application five majorcomponents, The bottom of monitoring equipment spherical integrated camera is responsible forcollection and compress audio and video signals inside the cabin, Sensor is responsible forimportant data collection. Network transmission layer is compressed packet for transmission,Center service layer is for audio and video server, user, and information management, Wireless Bridge is the audio and video compression packet wireless transmission to the monitoring center,real-time remote monitoring cabin, The monitoring center is to monitor and manage securityinformation inside the cabin. The system has important practical significance for improving thesafety performance of the automatic cabin.
