The Design And Practice Of The Main Line Optical Fiber Cable Circuit Inspection System Of China Unicom At Ji’an

The development of communication industry has come to 3G and super-speed Internet era with the feature of broadband.Broadband’s huge flow is based on the conveying basic network of great capacity,and its core is the main line optical fiber circuit transmission as a mainstay.The defences of the main line optical fiber cable circuit is the most important thing in the equipments’daily maintaining,and the inspection work is the most important link in ensuring the circuit safe.The article,starting from the actuality of the maintaining of the main line optical fiber cable circuit at China Unicom at Ji’an,and analyzing existent problems and defects in the process of maintaining impersonally,holds the opinion that the reason why the breakdown of the main line optical fiber cable happens frequently is that monitoring means is not perfect in the process of the safe defences at the main line.The article trys to design and construct a set of circuit inspection system applying computer and communication technology principles to replenish and perfect the monitoring means in the process of safe defences at the main line,and expects to achieve the goal that reducing times of breakdown and eusuring the main line optical fiber cable work without breakdown by daily maintaining to the main line optical fiber cable scientificly and efficiently.Around the design and structure of the circuit inspection system,the article introduces related technology principles of something,as short messages platform,the main line optical fiber cable circuit identification,relation data base,and so on.The article puts forward explicit demand to the system from users’ point of view,analyzing users’demand detailedly,and comes up with the design scheme of the system.At last,it introduces an available edition of the system’s design scheme. A trunk line the fiber optic cable circuit that surrounds Chi-an cruises the project design and the engineering fulfillments of check the systems, this thesis is total to is divided into five the chapters carried on to elaborate.In order to cruise to check the related technique of system, chapter 2 introduce related technique principles such as the short news terrace work principle, the trunk line fiber optic cable circuit marking system and the relation database etc., the point introduced the ADO database interview method.In order to cruise the project design of check the system, chapter 3 puts forward the explicit need to the system from the angle of the customer, carrying on the detailed analysis to the customer need, putting forward the total structure, each mold a design of that system, the database designs the design project of etc..In order to cruise the engineering fulfillment of check the system, chapter 4 the point introduced the engineering implement in the gearing that the equipments chooses the type and the system software, the deployment and networks of the network connect sex test, cruising to check the system application software to distribute, the actual circumstance that combine a trunk line fiber optic cable circuit maintenance management work of made to order the test data, give the test result.Since the system trys to run at China Unicom at Ji’an,the times of optical fiber cable interrupting decrease obviously,and working efficiency of inspectors increase obviously,so the system has positive effects to ensure the main line optical fiber cable work without breakdown. A trunk line the fiber optic cable circuit of Chi-an cruises the research of check the system, investigate to move another path of the position fixed position realm, then stand according to the ambulation the fixed position of the position. that system at try circulate, the fiber optic cable interruption number of times reduces obviously, cruising the work efficiency of check the personnel obvious exaltation, did not break down circulate to rose to promote the function actively towards insuring the trunk line fiber optic cable.
