| The arrival of the digital era, cable TV networks from a single integrated multifunction Internet transmission of television signals to the business world changes, including mock television signals, digital television signals and data services, such as telephone, grading and the maintenance of the network requirements have become more sophisticated. At present, how to guarantee a reliable and effective operation of the system as a whole, has become the subject of this paper. The article on digital cable transmission networks for the city of Lianyungang overview of the system and the advantages and disadvantages of maintaining the status quo analysis. After the previous network maintenance and repairs are basically, the entire network maintenance and management in a passive operations, the ability to improve the operation of the entire network, it is necessary to strengthen the maintenance and management of the network.Based Equipment Management Theory (ABC management) and system reliability analysis, a number of measures aimed at improving the system reliability, maintenance of equipment to establish different levels, stressing the importance of facilities management. The entire system is divided into three parts: the engine room, and the HFC network base stations, engine room equipment maintenance and highest quality, to ensure that key facilities are stable and reliable. Through analysis of the reliability of the system, to change the mistakes after maintenance, preventive maintenance, strengthening and extension of the useful life of equipment and lower costs. This paper emphasizes the importance of the equipment seized point, a set of feasible point inspection system and implement programs designed to modify or add some more scientific, standardized and effective system maintenance and management system.After a period of trial operation, the facts show that the design is feasible and effective, and the reliability of the system has been markedly improved. In the future of network management, the introduction of a comprehensive system of production and maintenance (TPM), the ideological and geographic information systems (GIS) technology, digital cable transmission network to enable the city to utilize and maximize the effectiveness and always reliable, and safe operating condition. |
