Method for automatically monitoring and maintaining optical cable

Abstract

The invention discloses a method for automatically monitoring and maintaining an optical cable. The method comprises the following steps of: automatically monitoring the power of the optical cable by a power meter and giving an alarm; when the power of the optical cable is alarmed, determining the alarm level of the optical power, and driving an optical time domain reflectometer module to test the optical cable; automatically analyzing whether the optical cable is broken and determining the breakpoint distance according to a test result; automatically calculating the geographical position of the breakpoint through optical cable facility information; automatically transmitting a short message to the mobile phone of an optical cable maintainer; and making an emergency maintenance by the maintainer or a manager. The invention is characterized in that: the method replaces the traditional polling mode so as to reduce the electric consumption, greatly improve the cruising capability of a handheld intelligent terminal, and improve the availability of the whole system; the optical cable is not required to be communicated with a server frequently so as to greatly save a general packet radio service (GRPS) flow; and when the optical cable is out of service, the server immediately transmits the message to the handheld intelligent terminal; and compared with the polling mode, the method has higher real time.

Description

technical field [0001] The invention relates to a method for maintaining an optical cable. In particular, it relates to an optical cable automatic monitoring and maintenance method with higher real-time performance. Background technique [0002] With the development of optical fiber communication technology and the continuous expansion of optical fiber communication networks, the large-scale application of optical cable automatic monitoring technology, how to repair optical cables faster and with higher quality and reduce the maintenance cost of optical cables is becoming increasingly important. [0003] After the current optical cable monitoring system detects an optical cable fault, it first manually inquires and calculates the approximate location of the optical cable fault, and then informs the relevant maintenance personnel of the information through paper documents, telephones, emails, etc., usually several maintenance personnel Investigate by gradually narrowing down...

Problems solved by technology

[0011] In the traditional optical cable maintenance process, maintenance personnel need to use a handheld OTDR to enter the computer room for testing. The test results need to be manually calculated to the corresponding geographical location, and then relevant maintenance personnel are notified for emergency repairs. Hours

[0012] In addition, on handheld mobile terminals, traditional applications mainly use polling methods, such as sending commands to the server to query the current alarm status at regular intervals. The timeliness of this method is mainly determined by the polling interval. When the interval is long, the timeliness is poor, but the power consumption and usage flow are small; the polling interval is small, the timeliness is good, but the power consumption and flow are relatively large

At present, the GPRS traffic fee is still relatively low. The main problem is that there is a contradiction between timeliness and power consumption.

[0013] As can be seen above, the traditional method has defects such as low efficiency, untimely information transmission, large scope of investigation, and labor and material resources consumption.
