[0022] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0023] Optical path data is an optical fiber path carrying service information and is crucial in the network construction and maintenance stages. It is the key to avoiding the same route in construction and positioning network maintenance problems. Due to frequent business changes, the cores in the optical cable equipment are inconsistent with the field.

[0024] Optical cable equipment (optical cross-connect box, optical fiber distribution box, terminal box, ODF), optical paths belong to dumb resources. Dumb resources mainly rely on manual maintenance. The newly added optical paths are forced to perform optical path scheduling during the service opening process to realize the scheduling management of incremental optical paths. However, due to the daily operation and maintenance, cutover work of the communication network, the optical path data is inconsistent with the actual site in the later stage, which in turn affects the accuracy of network planning and the timeliness of fault handling.

[0025] Dumb resources mainly provide resource data support for systems such as outsourcing maintenance, assets, and opening. At the same time, they provide resource data support for demand prediction and post-construction evaluation for planned construction. The inaccuracy of dumb resource data will affect the settlement of outsourcing maintenance fees, asset management, and the accuracy of network planning.

[0026] Since optical path data is not a separate resource entity, it is an optical fiber path formed by organizing various resources such as optical cables, optical cross-connects, ODF frames, cores, and ODF terminals. Usually, it takes a very long time to clear and check the surrounding optical cross-connects, optical cables and other resources when clearing and checking an optical path. At the same time, changes may occur about half a year after the clearing and checking. Therefore, it is very difficult to implement the inventory of optical path data.

[0027] Defects existing in the optical path resource management in related methods include: During daily maintenance, corrections can only be made for each type of resource separately. For example, optical cross-connects, optical cables, and optical paths are maintained separately. However, in actual scenarios, these three are a closely related network. Often, a change in one resource will also cause changes in others, making the modification complex and the workload large, resulting in low efficiency of on-site verification work.

[0028] The current optical path inventory needs to be organized specifically and cannot be well integrated with the existing daily work. The personnel responsible for pipeline resource inventory must understand the data model structure of complex resources and convert the on-site situation they see into resource data and then edit and modify the resource data. This requires a high level of knowledge reserve for personnel, and at the same time, the time required for data conversion is too long, resulting in low efficiency.

[0029] The inventory method in the related method requires manual verification of the consistency between the on-site situation and the resource data. If they are inconsistent, manual judgment is required to determine the resource data to be modified and then make the connection. The actual operation process is complex and the efficiency is low. How to improve the efficiency of optical path connection is an important issue that the industry urgently needs to solve at present.

[0030] In view of the defects in the related methods, the present invention provides an optical path connection method based on the inventory of pipeline dumb resources. Figure 1 It is a schematic flow chart of the optical path connection method based on the inventory of pipeline dumb resources provided by the present invention, as Figure 1 shown. The method includes the following: Step 110: Conduct on-site verification of each optical cable device in the optical path to be inventoried, and number each optical cable device according to the on-site verification results. Step 120: Based on the numbers in each optical cable device, determine the cross-connection relationship and fusion connection relationship information of each optical cable device. The fusion connection relationship is constructed based on the order of the core numbers at the termination and the order of the termination panel numbers, and the cross-connection relationship is constructed based on the optical cable core number, the number of the opposite-end facility, and the start and end numbers of the fiber cores. Step 130: Connect the optical path to be inventoried according to the cross-connection relationship and the fusion connection relationship information, and determine the path information of the optical path to be inventoried.

[0031] The execution entity of the optical path connection method based on pipeline dumb resource inventory provided by the present invention can be an electronic device, a component in the electronic device, an integrated circuit, or a chip. The electronic device can be a mobile electronic device or a non-mobile electronic device. Exemplarily, the mobile electronic device can be a mobile phone, a tablet computer, a laptop computer, a handheld computer, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc., and the non-mobile electronic device can be a server, a Network Attached Storage (NAS), or a personal computer (PC), etc. The present invention does not make specific limitations.

[0032] Taking a computer executing the optical path connection method based on pipeline dumb resource inventory provided by the present invention as an example, the technical solution of the present invention will be described in detail below.

[0033] In step 110, each optical cable device in the optical path to be inventoried is verified on-site, and according to the on-site verification results, each of the optical cable devices is numbered.

[0034] It should be noted that generally, multiple optical cable devices are included in the optical path to be inventoried. The optical cable devices can specifically include optical cross-connects, fiber distribution boxes, ODF frames, terminal boxes, etc.

[0035] Combined with network operation and maintenance patrol work, when the operation and maintenance personnel perform patrol work, the optical cable devices in the optical path to be inventoried are verified, and the verification information can be numbered and entered.

[0036] The verification of the optical cable devices includes capacity verification, panel verification, optical cable inventory, and fiber jumper inventory. Specifically, the capacity verification is to fill in capacity information such as the number of trays and the total number of terminals according to the characteristics of different optical cable devices, specifically including: Optical cross-connect: number of panels, tray number sequence, row number, column number, etc.

[0037] Fiber distribution box, ODF frame: tray number sequence, row number, column number, etc.

[0038] Terminal box: row number, column number, etc.

[0039] The panel verification mainly verifies whether trays are installed in the slots of the optical cross-connect, fiber distribution box, and ODF frame. If there is a tray in a certain card slot, the corresponding number is lit and marked.

[0040] The optical cable inventory is to record and fill in information such as the trays occupied by the optical cables in the optical cable devices going out of the station, the optical cable opposite end office direction, and the optical cable split fusion connection according to the trays occupied by the optical cables, the opposite end of the destination, and the core number in the on-site optical cable devices.

[0041] The fiber jumper inspection is to perform fiber optic cable jumpers according to the actual fiber jumper situation of the on-site ODF terminals in 4 ways: "single-core fiber jumper, double-core fiber jumper, single-core device fiber jumper, double-core device fiber jumper", and number the ODF terminals corresponding to the fiber jumpers according to the type and order of the fiber jumpers. The numbering rules are as follows: The numbering rule for single-core fiber jumpers (fiber jumpers between ODF terminals) uses "three-character representation". The first digit uses an English letter, and the second and third digits use Arabic numerals; e.g., H01, H02, H36, I01, I12; The numbering of single-core fiber jumpers is in the order of the first digit from H-Z-A for the fiber jumpers, that is, starting from the first letter H, and the second and third digits are numbered from 01-99 in sequence; the numbers of every two fiber jumper terminals are "the same"; The numbering rule for double-core fiber jumpers (fiber jumpers between ODF terminals) uses "three-character representation". The first digit uses an English letter (A-W, Z), the second digit uses an Arabic numeral (0-9), and the third digit uses X and Y respectively. The first two digits represent a pair of fiber jumpers, and the third digits X and Y are used to distinguish one of the fiber jumpers in a pair of fiber jumpers; e.g., A0X, A0Y, A1X, A1Y, B1X, B1Y, and A0 represents a group of fiber jumpers; similar to the single-core numbering, during the fiber jumper verification, the corresponding terminals are automatically numbered according to the order of the fiber jumpers, and the numbers are automatically cancelled when the fiber jumpers are cancelled; The numbering for single-core device fiber jumpers (fiber jumpers between ODF terminals and device ports) uses 2-digit Arabic numeral numbering + 1-digit letter numbering. The numerical numbering ranges from 10-99, and the letter numbering is (H-G), e.g., 01H, 02H, 11I, etc.; For double-core device fiber jumpers (fiber jumpers between ODF terminals and device ports), it uses 2-character representation. The first digit uses "X, Y", the second digit uses a number from "0-9", and the third digit is a letter numbering (A-Z, starting from H); among them, X represents the first fiber jumper, Y represents the second fiber jumper, and the same numbered last two digits form a group of fiber jumpers. For example, X0A and Y0A are a group of fiber jumpers.

[0042] In step 120, based on the numbers in the respective optical cable devices, determine the cross-connection relationship and fusion splicing relationship information of the respective optical cable devices. The fusion splicing relationship is constructed based on the order of the core numbers at the termination and the order of the termination panel numbers, and the cross-connection relationship is constructed based on the optical cable core number, the number of the opposite-end facility, and the start and end numbers of the fiber cores.

[0043] The fusion splicing relationship information is constructed based on the order of the core numbers at the termination and the order of the termination panel numbers. During the optical cable fusion splicing process, it is necessary to ensure that each optical fiber can be accurately connected to the corresponding device or optical cable, which involves the determination of the fusion splicing relationship.

[0044] The order of the number of cores at the termination refers to the arrangement order of the optical fiber cores when the optical cable is terminated (i.e., the connection and installation of the optical cable terminal). This order is usually determined according to the color coding of the optical fibers, the structural characteristics of the optical cable, and the construction requirements. During the fusion splicing process, it is necessary to strictly follow the order of the number of cores at the termination to ensure the accuracy and reliability of the optical fiber connection.

[0045] The order of the termination panel numbers refers to the arrangement order of the panel numbers on devices such as the optical fiber distribution frame (ODF) or optical fiber fusion splicing box when the optical cable is terminated. The panel numbers are usually used to identify different optical cables or optical fiber connection points, facilitating subsequent management and maintenance. During the fusion splicing process, it is necessary to connect the optical fibers to the corresponding panel numbers according to the order of the termination panel numbers.

[0046] It should be noted that there are a total of 3 scenarios for the fusion splicing of an optical cable at a certain optical device. The specific connection schematic diagrams can be as Figure 2 shown in the schematic diagram of the optical cable fusion splicing scenario provided by the present invention. Assume that the current optical cable device is "A".

[0047] Scenario 1: One outgoing optical cable A - B, only connecting points A and B; Scenario 2: Serial multiple outgoing optical cables A - B, terminating a part of the cores at B, and directly fusing a part of the cores with the optical cable B - C at the same time; Scenario 3: Parallel multiple outgoing optical cables A - B, at the branching joint F, directly fusing a part of the cores with the optical cable F - C and the optical cable F - B respectively at the same time.

[0048] By combining the order of the number of cores at the termination and the order of the termination panel numbers, the fusion splicing relationship information between optical cable devices can be constructed.

[0049] The cross - connection relationship is constructed based on the number of optical cable cores, the number of the opposite - end facility, and the start - end and end - end numbers of the cores. It is used to describe the connection relationship between optical cable devices and the transmission path of optical fibers.

[0050] The number of optical cable cores refers to the number of optical fibers contained in the optical cable. Different numbers of optical cable cores correspond to different transmission capacities and bandwidth requirements. When determining the cross - connection relationship, it is necessary to clarify the number of cores of the optical cable and the uses and functions of each optical fiber.

[0051] The number of the opposite - end facility refers to the unique identifier of the opposite - end device connected to the current optical cable device. This number is usually used to distinguish different devices or connection points, facilitating subsequent management and maintenance. When determining the cross - connection relationship, it is necessary to record the number of the opposite - end facility and its connection relationship with the current optical cable device.

[0052] The start - end and end - end numbers of the cores are used to identify the start and end positions of the optical fibers in the optical cable. Through the start - end and end - end numbers of the cores, the transmission path and connection points of each optical fiber can be clarified. When determining the cross - connection relationship, it is necessary to record the start - end and end - end numbers of each optical fiber and its specific position in the optical cable.

[0053] In step 130, according to the jump connection relationship and the fusion splicing relationship information, the optical path to be checked is connected in series to determine the path information of the optical path to be checked.

[0054] Specifically, the starting point of the optical path to be checked can be determined according to the jump connection relationship. Using the fusion splicing relationship information, trace the fusion splicing points of the optical fiber starting from the starting point. At each fusion splicing point, record the connection situation of the optical fiber, including which optical fibers are fused together and the directions of these optical fibers.

[0055] By continuously tracing the fusion splicing points, gradually construct the complete path of the optical path to be checked. During the construction process, it is necessary to continuously check the jump connection relationship and the fusion splicing relationship information to ensure the accuracy of the path.

[0056] When the end point of the optical path is traced, the correctness of the end point can be further confirmed according to the jump connection relationship. The end point is usually a specific fiber core on another optical cable device or optical fiber distribution frame.

[0057] As Figure 3 shown in the schematic diagram of the optical path connection structure provided by the present invention. The connection process is connected in series according to the fusion splicing relationship and the jump connection number; in an optical cable device, the next optical cable device can be found according to the jump connection relationship, and then continue to find the next optical cable device according to the jump connection relationship of the optical cable device until the jump connection reaches the active device port.

[0058] The optical path path connection method based on pipeline dumb resource inventory provided by the present invention realizes the pipeline dumb resource inventory process by on-site verification of each optical cable device in the optical path to be checked and numbering the optical cable devices according to the on-site verification results. Based on the numbers after inventory, the jump connection relationship and the fusion splicing relationship information are determined. Combining the jump connection relationship and the fusion splicing relationship information, the optical path to be checked is connected in series and the path information is determined, efficiently realizing the automatic connection process of the optical path path and making the path determination process more dependent on accurate data, improving the accuracy of path determination.

[0059] In one embodiment, based on the numbers in each optical cable device, determining the jump connection relationship and the fusion splicing relationship information of each optical cable device includes: based on the numbers in each optical cable device, constructing a three-level mapping relationship of ODF terminal numbers, fiber jumper numbers, and optical cable device port numbers, and based on the three-level mapping relationship, determining the device information triple of each optical cable device; based on a recursive algorithm, starting from any optical cable device among the optical cable devices, traversing the device information triples of each optical cable device to determine the jump connection relationship and the fusion splicing relationship information of each optical cable device.

[0060] Specifically, an Optical Distribution Frame (ODF) is an important device used for fiber optic connection and distribution in a fiber optic communication network. Each ODF terminal has a unique number, which is used to identify the position and status of the terminal. The fiber jumper number is used to identify the starting point, ending point of the fiber jumper and its position in the network. The cable device port number is used to identify the specific connection point on the cable device.

[0061] By associating the ODF terminal number, the fiber jumper number, and the cable device port number, a three - level mapping relationship can be constructed. This mapping relationship can be represented as a graph structure, where the nodes represent cable devices or terminals, and the edges represent fiber jumpers or connection relationships.

[0062] Based on the three - level mapping relationship, a device information triple can be determined for each cable device, including the device type (such as ODF frame, fiber jumper, cable splice closure, etc.), the device number, and the information of other devices or terminals connected to it.

[0063] A recursive algorithm is an algorithm that solves problems by calling itself within the function. When traversing the device information triples of cable devices, the recursive algorithm can start from any cable device and gradually traverse the entire network along the connection relationships. After the traversal is completed, the cross - connection relationship and fusion connection relationship information of each cable device can be determined based on the recorded information.

[0064] In one embodiment, connecting the optical paths to be inventoried in series according to the cross - connection relationship and the fusion connection relationship information to determine the path information of the optical paths to be inventoried includes: based on the cross - connection relationship, determining the starting device and the ending device in the optical paths to be inventoried; based on the fusion connection relationship information, determining the optical fiber core of the cable that is fiber - jumper - connected to the starting device; based on the cross - connection relationship, determining the ODF terminal connected to the opposite end of the optical fiber core; obtaining the fiber jumper number corresponding to the ODF terminal, and using this fiber jumper number as a new tracking starting point; gradually tracking the fiber jumper number until the other end of the cable corresponding to the fiber jumper number is the ending device, obtaining the fiber jumper number arrangement information; based on the fiber jumper number arrangement information, connecting the optical paths to be inventoried in series to determine the path information of the optical paths to be inventoried.

[0065] The cross - connection relationship records the connection relationships and destinations of each cable device. By analyzing the cross - connection relationship, the starting device and the ending device of the optical paths to be inventoried can be determined.

[0066] The starting device is the source of the optical path signal, usually a specific terminal on a certain transmitter or ODF frame. The ending device is the end point of the optical path signal, which is a terminal on a certain receiver or another ODF frame.

[0067] The splicing relationship information describes the connection relationship between the optical cable cores, including the connection details of the pigtails. Through the splicing relationship information, the optical cable cores starting from the starting device can be traced. According to the number of the starting device and the cross-connection relationship, the optical cable cores connected by pigtails are searched to ensure the accurate identification of the connected optical cable cores.

[0068] Through the cross-connection relationship, the ODF terminal connected to the other end of the optical cable core can be found. The ODF terminal has a unique number for identifying its position on the ODF frame. By querying the cross-connection relationship, the ODF terminal connected to the opposite end of the optical cable core can be accurately identified.

[0069] Each pigtail has a unique number for identifying its position and connection relationship in the network. By querying the pigtail information related to the ODF terminal, the pigtail number connected to the terminal can be obtained. The obtained pigtail number will be used as the starting point for the next-level tracing.

[0070] Through a recursive or iterative method, the connection relationship of the pigtails can be continuously traced until the termination device is reached. Starting from the starting device, the pigtail numbers are traced level by level, and each tracing uses the splicing relationship information and the cross-connection relationship to determine the next-level connection. During the tracing process, it is necessary to continuously judge whether the other end of the current pigtail is the termination device. Once the termination device is reached, the tracing process ends, and the complete arrangement information of the pigtail numbers is obtained.

[0071] Arrange the pigtail numbers obtained during the tracing process in the connection order to form the pigtail number arrangement information. The pigtail number arrangement information reflects the connection order and path of the pigtails in the optical path to be checked. Based on the pigtail number arrangement information, the complete path of the optical path to be checked can be determined.

[0072] In one embodiment, the numbering of each optical cable device according to the on-site verification result includes: obtaining the on-site device images of each optical cable device from the on-site verification result, performing object recognition on the on-site device images to determine the device information in the on-site device images; and numbering the devices corresponding to the device information according to the device category.

[0073] After obtaining the on-site device images corresponding to each optical cable device, deep learning models such as convolutional neural networks (CNNs) can be used to extract features and classify the images, so as to identify the optical cable devices in the images.

[0074] Match the collected images with the pre-prepared device templates, and determine the device type and information by calculating the similarity. Classify the identified devices according to the device category, such as ODF frames, pigtails, optical cable joint boxes, etc. Formulate a unified numbering rule for each device category, and assign a unique number to each device corresponding to the device information according to the numbering rule.

[0075] In one embodiment, after determining the path information of the optical path to be inventoried, it further includes: constructing a dummy resource management database for the optical path to be inventoried based on the numbers of the respective optical cable devices and the path information of the optical path to be inventoried.

[0076] Receiving the on-site verification information of the optical path to be inventoried sent by the operation and maintenance personnel, and updating the dummy resource management database based on the on-site verification information.

[0077] Enter the collected optical cable device numbers and path information into the corresponding database tables. Through the device numbers and connection relationships, associate the device table and the connection relationship table to form a complete device connection network. Associate the path information with the device connection network to ensure that each path in the path information table can correspond to specific devices and connection relationships.

[0078] The operation and maintenance personnel obtain the actual status information of the dummy resources in the optical path to be inventoried through on-site inspections. Sort out the received on-site verification information and extract key information such as device numbers, status changes, location information, etc. to prepare for subsequent database updates.

[0079] Compare the on-site verification information with the original information in the dummy resource management database to analyze the changes in the device status. If it is found through on-site verification that the connection relationship between devices has changed, such as fiber optic jumper replacement, connection point change, etc., update the relevant information in the connection relationship table in a timely manner.

[0080] For the problems of complex resource modification and large workload in daily maintenance, resources such as optical cross-connects, optical cables, and optical paths that are closely related can be uniformly managed. When one resource changes, the system will automatically update the information of other related resources without the need for separate maintenance. This associated management method not only simplifies the modification process, reduces the workload, but also improves the efficiency of on-site verification work.

[0081] For the problem that the existing optical path inventory needs to be specially organized and cannot be well combined with daily work, the inventory work is closely combined with daily operation and maintenance work. Through a smart phone or other portable intelligent terminals, operators can easily complete the collection and comparison of resource data during daily inspections without the need for a specially organized inventory activity. This inventory method that integrates daily work not only improves the inventory efficiency but also reduces the additional workload.

[0082] To address the issues that pipeline resource inventory personnel need to understand complex resource data model structures and that data conversion takes a long time, intelligent data collection and recognition technologies can be introduced. Through means such as image recognition and sensor data acquisition, the system can automatically extract key information of on-site resources and generate a format that matches the resource data. This intelligent technology reduces the requirements for personnel's knowledge reserves, shortens the data conversion time, and improves the efficiency and quality of the inventory work.

[0083] An automatic comparison and update mechanism is constructed to achieve automatic comparison and update of on-site data with the existing data in the system. When inconsistencies are found, the system will automatically prompt the resource data that needs to be modified and give modification suggestions. This automatic comparison and update mechanism reduces the time for manual judgment and operation and improves the accuracy and efficiency of the inventory work.

[0084] In one embodiment, the on-site verification of each optical cable device includes capacity verification, panel verification, optical cable verification, and fiber patching verification.

[0085] Specifically, the capacity verification is to fill in capacity information such as the number of trays and the total number of terminals according to the characteristics of different optical cable devices, specifically including: Optical cross-connect: number of panels, tray number sequence, row number, column number, etc.

[0086] Distribution box, ODF frame: tray number sequence, row number, column number, etc.

[0087] Terminal box: row number, column number, etc.

[0088] The panel verification mainly verifies whether trays are installed in the slots of the optical cross-connect, distribution box, and ODF frame. If there is a tray in a certain card slot, the corresponding number will be lit and marked.

[0089] The optical cable inventory is to record and fill in information such as the trays occupied by the optical cables in the on-site optical cable devices, the destination end, and the number of cores, including the trays occupied by the optical cables going out of the optical cable device, the optical cable destination end office direction, and the optical cable branch fusion splicing.

[0090] The fiber patching inventory is to perform optical cable fiber patching in 4 ways of "single-core fiber patching, dual-core fiber patching, single-core device fiber patching, dual-core device fiber patching" according to the actual fiber patching situation of the on-site ODF terminals. According to the type and sequence of fiber patching, the ODF terminals corresponding to the fiber patching are numbered. The numbering rules are as follows: Single-core fiber patching numbering rule (fiber patching between ODF terminals), using "three-character representation", the first character is an English letter, and the second and third characters are Arabic numerals; e.g., H01, H02, H36, I01, I12; The single-core fiber optic jumper is numbered in the order of the jumper. The first digit starts from H-Z-A, that is, starting from the first letter H, and the second and third digits are numbered sequentially from 01-99; the numbers of the terminals of every two fiber optic jumpers are "the same". The numbering rule for double-core fiber optic jumpers (fiber optic jumpers between ODF terminals) uses "three-character representation". The first digit uses English letters (A-W, Z), the second digit uses Arabic numerals (0-9), and the third digit uses X and Y respectively. The first two digits represent a pair of fiber optic jumpers, and the third digits X and Y are used to distinguish one of the fiber optic jumpers in a pair of fiber optic jumpers; for example: A0X, A0Y, A1X, A1Y, B1X, B1Y, A0 represents a group of fiber optic jumpers; similar to the single-core numbering, when checking the fiber optic jumpers, the corresponding terminals are automatically numbered according to the order of the fiber optic jumpers, and the numbering is automatically cancelled when the fiber optic jumpers are cancelled. The numbering of single-core equipment fiber optic jumpers (fiber optic jumpers between ODF terminals and equipment ports) uses 2-digit Arabic numeral numbering + 1-digit letter numbering. The numerical numbering ranges from 10-99, and the letter numbering is (H-G), such as: 01H, 02H, 11I, etc. For double-core equipment fiber optic jumpers (fiber optic jumpers between ODF terminals and equipment ports), 2-character representation is used. The first digit uses "X, Y", the second digit uses "0-9" numbers, and the third digit is letter numbering (A-Z, starting from H); among them, X represents the first fiber optic jumper, Y represents the second fiber optic jumper, and the same numbered bits in the last two digits form a group of fiber optic jumpers. For example: X0A and Y0A are a group of fiber optic jumpers.

[0091] Optionally, a verification system can be built to implement the on-site verification process of optical cable equipment.

[0092] After opening the verification system, to enter the optical cross-connection verification interface, after initiating a certain optical cross-connection verification task, enter the main page of optical cross-connection rectification verification. It supports the display of statuses of different steps such as unverified, being verified, and already verified. Each step supports returning to this interface to select a certain step to correct the content of this step.

[0093] Any subsequent step can return to this main interface to select a certain link for re-verification, but it must be a step before the current step. Re-verification may affect some data of the subsequent steps. Therefore, after submitting the update, the data that has been verified later needs to be updated. Mark "re-verification symbol" for the steps that need to be re-verified. When returning to the step that was just verified, submission is not allowed, and the re-verification of the previous steps needs to be completed.

[0094] The verification process mainly involves the basic attributes of the optical distribution box: the name of the optical distribution box, its longitude and latitude, address information, and specifications; a prompt for the difference between the longitude and latitude of the optical distribution box and the current location, with a prompt when the difference exceeds 50 meters: the current longitude and latitude are more than 50 meters away from the optical distribution box. Please select whether to update. If not, a reason needs to be filled in; when verifying the capacity of the optical distribution box, the actual capacity and the number of rows and columns of the on-site optical distribution box need to be filled in. It supports displaying the number of tray slots in each optical distribution surface and in each optical distribution surface of the optical distribution box; it supports adding the number of optical distribution surfaces; it supports deleting the number of optical distribution surfaces; it supports editing the number of tray slots in each optical distribution surface; it supports editing the total capacity of the optical distribution surface, the actual total capacity of the on-site optical distribution box; it supports initializing the trays, filling in the number of trays with different core numbers (6-core, 12-core), with a default of all 12-core; it needs to support the selection of row numbering, and the selection content is: from top to bottom, from bottom to top. After the verification of the optical distribution box capacity, the system automatically generates an optical distribution panel diagram under the full configuration. In the new optical distribution panel, a new "termination optical cable cross-connection relationship" is presented on each optical distribution box; the cross-connection relationship does not display the optical cable name, only the optical cable core number, the name of the opposite-end facility, and the starting and ending numbers of the fiber cores. When the tray is a 12-core tray, the fiber cores of terminals 1-6 and 7-12 are enlarged. This is convenient for quickly positioning the terminal numbers in the case of no numbering.

[0095] The verification of the optical distribution panel is carried out according to each panel of each surface, that is, if there are multiple panels on one surface of the optical distribution box, each surface is verified one by one. When there are trays not inserted in the panel of the optical distribution box, the redundant trays are removed through this function; after removing the trays, the tray numbers do not change; if you want to restore the trays, enter the "panel configuration" interface again and uncheck them; for some variant trays, such as the 24-core case, the terminal data of a certain tray is modified.

[0096] Optical cable verification: Verify one optical cable data each time; after clicking the optical cable verification button, the optical cable information filling interface is opened; then fill in the information of the newly added optical cable in the next interface: the optical cable core number, the number of destinations, etc.; the number of destinations in the interface is determined by the "number of optical cable destinations" at the top. The optical cable destination data includes the different facilities at the opposite end of the termination of the optical cable in this optical distribution box and the direct fusion of the optical cable with other optical cables in this optical distribution box. After filling in, the optical cable destination description of the corresponding optical cable panel is presented. If it is incorrect, you can go back to the previous step to modify. After the verification of one optical cable information is completed, it is automatically updated to the panel diagram according to the filled optical cable information. The terminals of the tray change to the "termination idle" state, and the core number and cross-connection relationship of this optical cable are displayed on the right; after the successful verification of the optical cable, the summary information of this optical cable is displayed on the "verify optical cable" interface.

[0097] Verification of terminals and pigtails: This step is to verify the occupancy, idle status, pigtail relationship, etc. of the terminals based on the previous steps. In the verification state, click on the used terminals one by one, supporting multi-selection. After clicking "Confirm", the system automatically changes the status of the terminal to "occupied". The terminals of the un-terminated optical cable cannot be occupied. Only the "terminated" ODF terminals are displayed in this interface. The un-terminated terminals are not shown here. This step needs to record the differences between manual revision and image recognition for statistical analysis of image recognition.

[0098] After verifying the occupancy status of the ODF terminals, verify the pigtail situation between the actual terminals. This will affect the optical path data during this process.

[0099] This function is to establish a connection relationship (i.e., pigtail) between two "terminated" ODF terminals in the optical cross-connect panel. Repeatedly click on a terminal, and the terminal status will return to the "idle" state. The operations are divided into four categories: "single-fiber", "dual-core", "single-fiber device pigtailing", and "dual-fiber device pigtailing". Single-core pigtailing: In this state, click on two single-core pigtailing terminals one by one. The system defaults it as the pigtail of one optical path. Multiple operations can be continuously performed in one state.

[0100] Dual-fiber pigtailing: In this state, click on the two ODF terminals for pigtailing one by one. The system defaults that every two groups of pigtails are one optical path. The continuous pigtailing mode is supported.

[0101] All occupied ODF terminals must be pigtailed.

[0102] When pigtailing, when clicking on the first ODF terminal of the two ODF terminals with an existing pigtail, the second terminal will be highlighted. When there is a cross-panel pigtailing situation, it supports clicking on the tab page of other panels for pigtail selection.

[0103] To conveniently and intuitively display the grouped relationship of the pigtails and facilitate on-site verification personnel to proofread and view the pigtail relationship on-site, it is necessary to number the terminals while pigtailing.
