Remote monitoring system and monitoring method for underground communication cable

Abstract

The invention relates to a remote monitoring system and a monitoring method for the underground communication cable. The system comprises an inflator and a data collector; the air pressure sensor, the inflator and the data collector are arranged according to the direction by a underground communication cable and are connected with the underground cable on one hand, and are connected with the telephone network on the other hand; meanwhile, a monitoring computer is connected with the telephone network through a modem. When in use, the monitoring computer sends monitoring instructions regularly; the cable inflator and the data collector respectively send back the running state of the inflator, the warning message and air pressure signals from each monitoring point for the underground communication cable in time; the data collected is saved in the monitoring computer; when a warning message turns out on the inflator, the message is sent to the monitoring computer, and the monitoring computer saves the message and analyses and processes the data, and then a warning is given out on the computer through sound, light and other signal mode to promote the operator to process. The invention has the advantages that the reliability, real-time performance, safety and other performance of monitoring underground cable are greatly improved.

Description

technical field [0001] The invention relates to underground wired communication lines, in particular to a remote monitoring system for monitoring and maintaining underground communication cables and ensuring the safe operation of communication lines by inflating and measuring pressure, and belongs to the technical field of wired communication. Background technique [0002] In modern society, the communication cable network has played a pivotal role, which has effectively promoted the rapid development of economic construction in various countries and the significant improvement of people's quality of life. The safe operation of communication cables—especially underground communication cables is related to the national economy and the people's livelihood, and will directly affect the service quality of the main business and value-added services of telecommunications companies. However, while people are vigorously developing the construction of communication cables, the monito...

Problems solved by technology

However, there are many deficiencies in this type of remote monitoring system in the prior art. For example, in the line center of the network department of a municipal telecommunications bureau in China, the database server of the cable air pressure monitoring management system is an HPL3000, and the sybasell database software is installed. 14683 sensors in the city For collection, the average cycle of the system is 2 hours, and the air pressure value measured by the sensor is normal in most cases, and the database cannot filter the same data, resulting in certain data redundancy; moreover, the database does not have a hot backup mechanism, such as There is no reasonable and effective recovery mechanism in case of an accident

Due to the long working cycle, the air pressure data of the sensor lags behind, and the monitoring center cannot adjust in time
