Description

Root cable barrier section root cause analysis method

The invention relates to a method for analyzing the root cause of a submarine cable obstacle section, in particular to a circuit of a submarine cable device and a circuit attached to the submarine cable when an obstacle is generated by using a submarine cable, and having an alarm-related characteristic, and a set of sea developed Cable segment barrier detection technology.

On August 12, 2009, typhoon Morakot caused a sea-rock flow, causing the disruption of five international submarine cables from SMW3, APCN, APCN2, EAC and FNAL/RNAL to the south, including: Taiwan to Shantou in China and Singapore in Southeast Asia. Communication between the Philippines and Hong Kong was blocked. Internet, enterprise customer circuits and voice circuits were all affected. After several days of scheduling and support, Taiwan and these countries gradually resumed normal communication, which shows the importance of cable handling. Sex. When the submarine cable is in trouble, the international submarine cable company will conduct obstacle detection in the submarine cable section. After detecting the source of the obstacle, it will notify the national submarine cable transportation center to carry out the submarine cable dispatching work, and then notify the personnel of the maintenance center. Network support and scheduling work is performed in each network center.

Due to the current detection technology of the submarine cable obstacle section, it is completely in the hands of the international submarine cable company. The immediacy of handling the submarine cable obstacles for the submarine cable transportation personnel will be affected by the speed of the international submarine cable company notification, and the submarine cable obstacle At the same time, the transmission circuit and the voice circuit are affected. The invention analyzes the obstacles of the transmission circuit and the voice circuit for the purpose of judging the obstacle of the submarine cable, and the judgment of the dry contact point can greatly increase the obstacle judgment of the submarine cable section. The submarine cable maintenance personnel also judge the submarine cable obstacles according to this rule. However, when the submarine cable is repaired, the submarine cable feeding equipment is often ON/OFF. At this time, only the dry contact point judgment will be misjudged, and a large number of circuit alarms are transmitted. The assistance of the obstacle judgment can exclude such a situation. Therefore, the present invention proposes to utilize the design of the submarine cable equipment alarm and the submarine cable section correspondence table and the cable occlusion circuit threshold value, and can instantly detect when the submarine cable has an obstacle. The submarine cable section in which the alarm occurred can be detected before the international submarine cable company has not notified, the previous patent technology I308828, patent I30882 8 (Centralized Transmission Network Obstacle Source Analysis System) provides users to input single or multiple obstacle circuits, analyze the network equipment database to find possible obstacle sources, and find the obstacle source by manually inputting alarms. There are two shortcomings. First, there is no immediacy. When the alarm is generated, the network administrator is not necessarily at the scene. When the person is not at the scene, the function cannot be exerted. Second, the lack of accuracy, the patent does not mention the specific The network architecture finds the source of obstacles. When large disasters occur, such as earthquakes and typhoons, network equipment damage, due to excessive input barrier circuits, the results will be too scattered to play its role. There are still many shortcomings in the above-mentioned conventional techniques, which is not a good designer, but needs to be improved.

National telecommunications submarine cable management and dispatch personnel.

The method for analyzing the root cause of the submarine cable obstacle section which can achieve the above object is to design an aerobic cable section obstacle detection when the submarine cable equipment and the circuit attached to the submarine cable have an alarm-related characteristic. Measuring technology, the present invention proposes two steps to find the submarine cable obstacle section, the first step, which can be divided into two work, the first working system utilizes the submarine cable equipment alarm and the cable cable section obstacle correlation analysis method to the submarine cable equipment The alarm signal is transmitted to the submarine cable equipment alarm signal conversion device through the dry contact point, and the device converts the logic signal of the submarine cable equipment alarm into a digital data format, and the digital data is compared with the submarine cable device and the submarine cable segment corresponding table. Yes, it can be concluded that the submarine cable equipment deducts the list of obstacles in the submarine cable section, and the second work system uses the circuit alarm and the submarine cable section correlation analysis method to detect and transmit the circuit alarm to the circuit alarm receiving device through the circuit alarm detecting device. Then, the alarm data contained in the circuit is compared with the corresponding table of the circuit alarm submarine cable section, and the total number of obstacle cable sections is generated, and then the obstacle circuit door of the submarine cable section is generated. Value correspondence table for comparison, generating an alarm circuit submarine inference section disorder list, the first and second job has been deduced disorders submarine cable section, a second step is performed. In the second step, the submarine cable equipment is inferred from the list of obstacles in the submarine cable section and the circuit alarms are deduced from the list of submarine cable obstacle sections. The convergence and convergence of the submarine cable section are used to compare and match the list of the submarine cable obstacles. Get a submarine cable barrier section.
