Description
Technical Field
The present invention relates generally to fiber optic communications technology, and more particularly to a method, apparatus and system for fast fault location of optical cables.
Background
Cable line faults are a major cause of blocking of communication traffic transmission. At present, the repair of an Optical cable line fault is mainly performed by manual positioning and first-aid repair, that is, a line maintenance department performs tests such as Optical fiber length, Optical fiber transmission attenuation, joint attenuation, fault positioning and the like on the Optical cable line with the fault in a machine room or an end point position through OTDR (Optical Time Domain Reflectometry) equipment, determines a distance from a fault point to a test end point, and then manually calculates an approximate position of the fault point by searching Optical cable line completion data (for example, design paper) and the like and combining the tested distance from the end point to the fault point. In this method, the length error caused by the optical fiber splice tray retention, the twist shrinkage rate and the like is also considered when determining the position, which adds a large amount of work to the actual work and often seriously affects the accuracy of fault point positioning because completion data is incomplete or inaccurate.
Furthermore, some methods utilize an OTDR module integrated on an OLT (Optical line terminal) device in a PON (Passive Optical Network) or an OTN (Optical Transport Network). Although the integrated OTDR module simplifies the optical cable fault detection procedure, it has a similar defect to the separately used OTDR, that is, data associated with the optical cable can still only be obtained by OTDR measurement, and then manual data search is required to calculate the fault location.

Detailed Description
Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings, elements and components shown in the exemplary embodiments are only illustrative, and the scope of the present invention is not limited to these elements or components.
Fig. 1 shows a system architecture diagram of a cable fault quick location system 100, according to an embodiment of the present invention. The cable fault quick location system 100 includes an OTDR 110, an intelligent terminal 120, and a pipeline resource system 130. OTDR 110 has the fiber testing functionality of OTDRs commonly used in the relevant field to test various parameters associated with fiber lines, such as fiber length, transmission attenuation of the fiber, splice attenuation, distance of test endpoints from fault points, and the like. The OTDR 110 further integrates a data input/output module 112 such as bluetooth, infrared, NFC, or other wireless communication technologies conforming to a data transmission protocol or audio (3.5mm) data input/output interface, which can be driven by a modulation signal protocol (high/low level) matching with the smart terminal, so as to perform data interaction with the smart terminal 120.
The smart terminal 120 may be any handheld smart device with wireless communication capabilities, such as a smart phone, PDA, tablet device, laptop, and the like. The smart terminal 120 has a fault fast location function (e.g., APP)122 and may communicate with the OTDR 110, for example, via bluetooth, to obtain parameters associated with the fiber line, and to send resource data requests to the pipeline resource system 130 and receive network resource data from the pipeline resource system 130 via the mobile data network. Then, the smart terminal 120 locates its location and confirms the testing endpoint by means of automatic or manual selection and search confirmation of a GPS module, a wireless network (e.g., WLAN, Wi-Fi, etc.), a mobile data network (e.g., LTE, UMTS, GSM, etc.), and a GPS module configured thereon. The fault fast positioning function 122 on the intelligent terminal 120 performs location matching and calculation on the test result data (e.g., the length of the optical fiber, the transmission attenuation of the optical fiber, the joint attenuation, the distance of the fault point, etc.) transmitted by the OTDR and the network resource data acquired from the pipeline resource system 130 to obtain the geographical location information of the fault point, so as to quickly locate the position of the fault point and present the position in the electronic map.
The pipeline resource system 130 is a database system with complete daily maintenance data by engineering and line maintenance personnel, and stores dummy resource data such as a pipe network, a rod network, and an optical cable network, and most of the resource data have geographic location information (e.g., longitude and latitude). The pipeline resource system 130 interacts with the intelligent terminal 120 through a network interface.
The invention provides a method and a system for quickly positioning optical cable faults, which can send test results to an intelligent terminal (for example, a handheld intelligent device) by configuring a wireless communication technology such as Bluetooth, infrared and NFC or an audio (3.5mm) input/output interface on OTDR equipment. The intelligent terminal calls data in the pipeline resource system through a wireless network or a mobile data network, and performs joint analysis on the OTDR test result and the data of the pipeline resource system, so as to automatically position the accurate geographical position of the fault point and feed the accurate geographical position back to the intelligent terminal, thereby achieving the purpose of quickly and accurately positioning the fault point.
FIG. 2 illustrates a flow chart of a method for rapid location of a cable fault according to an embodiment of the present invention. In step 201, a faulty fiber line is tested at a test endpoint using OTDR 110 and test results are generated, including, for example, fiber length, transmission attenuation of the fiber, splice attenuation, distance of the test endpoint from the fault point, etc.
In step 202, the intelligent terminal 120 sends a request for a test result of the faulty fiber line to the OTDR 110 through a wireless network or a mobile data network.
In step 203, the OTDR 110 sends the test result on the faulty fiber line to the intelligent terminal 120 in response to the request received from the intelligent terminal 120.
In step 204, the intelligent terminal 120 sends a network resource data request regarding the failed fiber optic line and the geographic location (e.g., latitude and longitude) of the intelligent terminal 120 to the pipeline resource system 130.
In step 205, the pipeline resource system 130 sends information of the test endpoints matching the geographical location of the intelligent terminal, including information associated with one or more of a machine room, an optical distribution frame ODF, an optical fiber terminal, etc. that maintains the optical cable, to the intelligent terminal 120 in response to the network resource data request sent by the intelligent terminal 120 regarding the faulty optical fiber line.
In step 206, the intelligent terminal 120 selects a test endpoint associated with the OTDR from the received test endpoints and sends information of the selected test endpoint to the pipeline resource system 130.
In step 207, the pipeline resource system 130 sends network resource data about the faulty fiber optic line matching the selected test endpoint to the intelligent terminal based on the information of the test endpoint.
In step 208, the intelligent terminal 120 determines the geographical location (e.g., latitude and longitude) of the fault point of the faulty fiber optic line based on the test results and the network resource data.
FIG. 3 shows a flow diagram of a method for fast cable fault location according to an embodiment of the present invention. In step 301, for example, a line maintenance user tests a fiber line using OTDR 110 having data input output module 112 at a test endpoint and obtains a test result.
In step 302, the line maintenance user starts the fast fault location function 122 on the smart terminal 120, and the fast fault location function 122 may be an application implemented on the smart terminal.
In step 303, based on the fast fault location function 122 being activated, the intelligent terminal 120 sends a test result request to the OTDR 110.
In step 304, in response to the test result data request, OTDR 110 sends test result data, including the distance from the test endpoint to the fiber fault point, the distance to each splice point, the splice point, and so on, to intelligent terminal 120 through data input output module 112.
In step 305, the fault fast-positioning function 122 sends a network resource data request to the pipeline resource system 130 via the wireless network or the mobile data network, and simultaneously sends the geographical location (e.g., longitude and latitude) of the intelligent terminal 120 itself.
In step 306, the pipeline resource system 130 sends test endpoint information (e.g., data for a room, ODF, terminals, etc.) matching the geographic location of the intelligent terminal 120 to the intelligent terminal 120 based on the geographic location of the intelligent terminal 120.
In step 307, the line maintenance user selects the current actual test endpoint information from the test endpoint information received by the fault fast positioning function 122 and sends the selected test endpoint information to the pipeline resource system 130 in step 308.
In step 309, the pipeline resource system 130 sends network resource data matching the test endpoint, such as information about a cable segment, a pipe hole, a sub-pipe hole, a pipe segment (a rod segment, a buried segment), a terminal port, a manhole, a pole, a monument, a coil, a joint, a connection location, an optical facility, etc. associated with the optical fiber line to the intelligent terminal 120 based on the test endpoint information.
In step 310, the fault fast-location function 122 determines the specific location of the fault point based on the distance from the test endpoint to the fault point obtained from the OTDR 110 in combination with the network resource data received from the pipeline resource system 130. Since the fiber optic cable associated with the failed fiber has a complete line location data set in the pipeline resource system 130, the specific location (e.g., latitude and longitude) of the fault point can be calculated by adding the location of the test endpoint to the distance from the test endpoint to the fault point obtained from the OTDR test.
Optionally, in step 311, the fault fast-positioning function 122 outputs and displays the specific location (e.g., latitude and longitude) of the fault point in an electronic map to show the line maintenance user, and provides resource information associated with the failed optical fiber to facilitate the line maintenance user to quickly find the fault point during the site construction.
Fig. 4 shows a schematic diagram of an intelligent terminal for fast location of optical cable faults, according to an embodiment of the invention. As shown in fig. 4, the intelligent terminal 420 includes a receiving device 421, a transmitting device 422, and a positioning device 423. The sending device 421 of the intelligent terminal 420 is configured to send a request about a test result of the faulty optical fiber line to the OTDR, send a request about network resource data of the faulty optical fiber line and its own geographical location to the pipeline resource system, and select a test endpoint associated with the OTDR from the received test endpoints and send information of the selected test endpoint to the pipeline resource system. The receiving means 422 of the intelligent device 420 is used to receive the test results on the faulty fibre line from the OTDR, to receive information of the test end points matching the geographical location of the intelligent terminal from the pipeline resource system, and to receive network resource data on the faulty fibre line matching the selected test end points from the pipeline resource system. The locating device 423 is configured to determine a geographical location of a point of failure of the failed optical fiber line based on the test results and the network resource data.
Fig. 5 is a flowchart illustrating a method for performing fast cable fault location by an intelligent terminal according to an embodiment of the present invention. In step 501, the intelligent terminal sends a request for test results of the faulty fiber line to the OTDR.
Test results for the faulty fiber line are then received from the OTDR in step 502, including the distance from the test end point to the fiber fault point, the distance to the respective splice point, etc.
In step 503, the intelligent terminal sends a network resource data request regarding the failed fiber optic line and its own geographic location (e.g., latitude and longitude) to the pipeline resource system. The pipeline resource system stores network resource data such as a pipeline network, a rod network, an optical cable network and the like and corresponding geographic positions. Next, the process of the present invention is described,
in step 504, the intelligent terminal receives information of the testing endpoint matching its geographic location from the pipeline resource system.
In step 505, the line maintenance user selects a test endpoint associated with the OTDR from the received test endpoints on the intelligent terminal and sends information of the selected test endpoint to the pipeline resource system through the intelligent terminal.
In step 506, the intelligent terminal receives network resource data about the faulty fiber optic line from the pipeline resource system that matches the selected test endpoint, such as information about a cable segment, a pipe bore, a sub-pipe bore, a pipe segment (a pole segment, a buried segment), a terminal port, a hand well, a power pole, a monument, a coil, a splice location, an optical facility, etc. associated with the faulty fiber optic line.
In step 507, the intelligent terminal determines the geographical location (e.g., longitude and latitude) of the fault point of the faulty fiber optic line in combination with the test results and the network resource data. Optionally, the intelligent terminal displays the geographical position of the fault point in an electronic map, so that a line maintenance user can conveniently find the fault point quickly and accurately.
Fig. 6 shows a block diagram of an OTDR according to an embodiment of the invention. As depicted in fig. 6, optical OTDR 610 has a data input output module 611, which may be implemented by any one of bluetooth, infrared, NFC, 3.5mm interface. OTDR 610 receives a request for a test result on a faulty fiber line through data input output module 611, tests the faulty fiber line to obtain the test result, and sends the test result to the intelligent terminal through data input output module 611, so that the intelligent terminal determines a fault point of the faulty fiber line in combination with network resource information received from the pipeline resource system, where the network resource information is information on a test endpoint selected from among test endpoints provided from the pipeline resource system in relation to location information of the intelligent terminal.
