Design And Implementation Of Digital Surveillance And Monitoring System Of The JISCO Headquarters

Video surveillance and monitoring system is the result of the colligation application of multimedia technology, computer net, industry control and artificial intelligence, and it is developing towards the direction of audio and video digitization, system net and intelligence management. According to the development of video monitor technology, the video monitor system is approximately divided into three phases:analog video monitor system, digital video monitor system and distribute video monitor system.In 1987, the Jiu Steer founded the first local analog video monitor system, which is' mainly applied to monitor the operation of the product line of rolling mills equipments. Later, some working procedures, which are worked for the production management and the demand of operations, gradually founded the centers of the local monitor system, which is based on the regions. These monitor systems were the analog monitor system, used the coaxial-cable or wireless transmission, and a great quantities of matrix, video multiplexer, neighbor-frequency demodulator, video tape recorder and other analog equipments, only provided the picture for the position or the monitor center, and did not accomplish the share of the image data.In 2002, the JISCO founded the production headquarters, carried out the management of the production organization. At the same time, the company made the selection of the data, and did lots of the construction work of the information foundation. How to design a long distance digital surveillance and monitoring system, which was consisted of the good quality of real-time, the low time delay, the low bandwidth and the convenience of saving search, transmitted the scattered analog monitor images, which is in the several miles regions or even in the several ten-miles region, to the company net, made the production headquarters and relevant position to master the state of the production equipment and the locale for the centralized monitoring and purview management, became a bran-new research topic.By researching kinds of the standard of MPEG and analyzing their characters, combining the requires of the JISCO Headquarters, considering the demands of the real-time characteristics, network bandwidth and data compression, the paper is aimed for formulating the image compression standard which is adopted by the JISCO Headquarters'Digital Surveillance and Monitoring System. The formulation of the standard makes an clear direction for the JISCO Headquarters' Digital Surveillance and Monitoring System, and provides a regulation for the construction of the monitor system of the process performance evaluation in the future. So it is very meaningful. At the same time, I particularly designed a complete long-distance digital monitor control system based the standard for the JISCO Headquarters. Based on the formulation standard, the JISCO Headquarters'Digital Surveillance and Monitoring System has worked more than four years, successfully achieved the goal of the original design, and made an great contribution for the JISCO.
