In the existing communication resource management system, external resources such as optical cables, pipelines, pole lines and the like are the key points of optical path network management. It has the obvious characteristics that: the optical cable and the line have wide distribution range and large resource information amount, and have direct connection relation with upper-layer equipment and lower-layer customers. Telecommunication operation maintenance workers make business with a large amount of optical cable data information every day, but the use states, use conditions, asset information and the like of a large amount of optical cables are difficult to be mastered through manual management, and the increasingly complex and growing data are difficult to be effectively and quickly managed through simple system management.
The existing pipeline resource management system only realizes the management of physical resources such as optical cables, pipelines, pole lines and the like, the main system function is only resource input, the management of the dummy resources cannot accurately reflect the current situation of the existing optical cable resources, and effective support cannot be provided for the work of network maintenance, resource scheduling, resource utilization and the like; the main problems in the existing pipeline resource system are as follows:
1. the optical cable network bears upper layer networks such as a transmission network, a data network and the like, and the logic relationship exists among different optical cables, but the logic relationship among fiber cores is not reflected in the existing pipeline resource system;
2. the field fiber core service names are not uniform: the names of the same service in different optical cable sections are inconsistent, which means that tail fiber labels of optical cable end-forming frames at different stations are inconsistent and cannot be automatically associated;
3. the rental pipeline is not incorporated into the system;
4. the hidden danger of the optical cable cannot be automatically presented: the system cannot automatically troubleshoot hidden dangers of the optical route.
In the field of optical communication, an optical path is adopted to record a series of interconnected fiber cores or channel information; the optical path is a logic concept, and the optical path realizes the encapsulation of the lower layer fiber core and the optical cable information, and corresponds to the upper layer directly with a transmission topology or a service system, that is, the optical path is a bridge for connecting communication service information with the optical cable and the fiber core information. The basic attributes of the optical path include an optical path name, an optical path route, opening time and the like, wherein the optical path name is a unique identifier of the optical path, and the optical path route records detailed information of the optical path, such as an ODF, an optical cable segment, a splice closure and the like.
Multiple optical paths of the same optical fiber loop are prevented from passing through the same optical cable, and if multiple optical paths pass through the same optical cable, the optical paths are considered to be in the same route; if the optical cables on the same route of the optical path are broken, communication interruption occurs at the stations on the loop. As shown in fig. 1, on the optical fiber communication loop, a rerouted optical path occurs between the site a4 and the site a5, and if the optical cable is broken between the site a4 and the site a5, the site a5 will be disconnected, and the service will be interrupted. The current optical path management system has the following defects: the same routing condition of the main optical path loop, such as the same routing of the two optical paths between the stations a4 and a5 in fig. 1, cannot be quickly and intuitively checked, but in the existing optical path management system, the optical path condition in the same optical cable is difficult to identify.
Patent application CN201410718439.8 discloses an optical cable intelligent resource management system and an intelligent management method, which includes: intelligent chip, handheld terminal and backstage management system in the implantation optical cable, backstage management system includes: the system comprises an optical cable resource database, a data receiving module, a data transmission module and a data comparison module; the optical cable resource database is used for storing optical cable identification codes and optical cable information corresponding to the optical cable identification codes, the data receiving module is used for receiving information obtained through the handheld terminal, the data comparison module is used for comparing the information received by the data receiving module with the information in the optical cable resource database, and the data transmission module is used for transmitting the compared optical cable resource information to the handheld terminal.
