Description

  The present invention relates to a maintenance / operation system for an automatic optical fiber connection switching device that automatically switches an optical fiber connection in an optical network.

  An operation of connecting or disconnecting an arbitrary input side optical fiber and an arbitrary output side optical fiber to a plurality of input / output fiber groups may be performed. For example, an input / output fiber group is connected to an optical fiber cable entering from the line side of a communication center building or intelligent building as an input side, and connected to an optical fiber cord deployed on each floor of the building as an output side. The Conventionally, the optical connection switching operation for newly establishing, changing, or removing the optical connection route between the track side and the floor is, for example, an input / output connector using commercially available FC type, SC type, or MU type optical connectors. Has been carried out manually using a patch panel in which a large number of patches are arranged.

  Conventionally, as shown in FIG. 7, an input side board 702 and an output side board 703 are provided on the front surface of the patch panel 701. A plurality of optical connector adapters 704 (hereinafter referred to as adapters) penetrating the patch panel 701 are arranged on the input side board 702 and the output side board 703. Each adapter 704 is numbered sequentially according to a predetermined standard. As shown in FIG. 7A, the input side optical fiber cord 705 is connected to the adapter 704a of the input side board 702, and the output side optical fiber cord 706 is connected to the adapter 704b of the output side board 703. . In this case, in order to connect the input side optical fiber cord 705 and the output side optical fiber cord 706, one end of the optical jumper cord 707 is formed on the back surface of the patch panel 701 as shown in FIG. The connector plug provided on the other end may be connected to the adapter 704a, and the connector plug provided on the other end may be connected to the adapter 704b. Conversely, in order to release the connection, the two connector plugs of the optical jumper cord 707 may be removed from the adapters 704a and 704b. That is, the optical connection route can be changed by replacing the optical jumper cord 707.

  In this case, the field worker acquires in advance the adapter number of the adapter 704 to which the optical jumper cord 707 to be switched is connected and the changed adapter number. Since the combination of the currently connected connector plug and adapter is stored in a database or the like as wiring information related to the wiring of the optical connection route, the field worker prints out and acquires the information in this database. Then, based on the acquired adapter number and the changed adapter number, the connection switching work is advanced while collating the adapter number written on the patch panel 701. On the other hand, after the connection switching operation by the operator is completed, the operator performs an operation of updating the wiring information stored in the database.

  By the way, when the wiring density of the optical fiber cord exceeds the scale of several cores to several tens of cores, and the wiring density increases, the field worker can select the optical jumper cords necessary for connection switching from a large number of wiring groups. It becomes difficult to select 707. In such a scale, while the existing optical jumper cord 707 is scraped, the connector plug of the new optical jumper cord 707 is connected to the target adapter 704, or the optical jumper cord 707 of the unnecessary line is removed. It becomes difficult. As a result, erroneous connection or disconnection due to human error may occur.

Thus, an automatic optical fiber connection switching device has been proposed in which optical connection switching work is automated by operating an arbitrary optical fiber cord with a robot hand (see, for example, Patent Document 1). By using this automatic optical fiber connection switching device, erroneous connection and erroneous disconnection can be prevented.
JP-A-7-318820 (paragraphs 0010 to 0015, FIG. 2)

  However, the technique described in Patent Document 1 causes an input error by an operator when updating the wiring information stored in the database after the connection switching operation is completed even when erroneous connection or erroneous disconnection does not occur. Sometimes. For this reason, every time an input is made, a check operation must be performed, and the operation for managing the wiring state of the optical fiber cord is very complicated.

Can be calculated. In addition, a drive command is generated from the calculated wiring route, and the generated drive command is transmitted to the controller by the communication module. Then, the controller controls the robot mechanism and the moving mechanism of the automatic optical fiber connection switching device, so that the maintenance / operation system of the automatic optical fiber connection switching device can execute the connection switching of the connection optical fiber without human intervention. . Further, when the connection switching of the connection optical fiber is normally completed, the management function module of the operation terminal automatically updates the terminal information stored in the management database. Therefore, the connection switching operation and the terminal information stored in the management database can be managed in conjunction with each other. In addition, since the operation terminal and the controller are connected using a communication line, an optical fiber connection switching device can be provided at a remote location from the operation terminal. As a result of performing the optical fiber connection switching work by remote control from the operation terminal, the worker is moved to a remote place where the optical fiber connection switching device is installed in order to perform the connection switching work. This eliminates the need for dispatch, and can greatly reduce operational costs.

In order to solve the above problems, the maintenance / operation system for the automatic optical fiber connection switching device of the present invention is configured to connect any one of the input optical fiber and the output optical fiber via an adapter. The optical fiber for connection, which is an optical fiber, is handled by a robot hand, and the optical connector plug provided at the end of the optical fiber for connection is attached to and detached from the adapter, thereby performing the optical connection work or the connection release work.

With this configuration, the maintenance / operation system of the automatic optical fiber connection switching device can manage the connection switching operation and the terminal information stored in the management database in conjunction with each other, and the operation of the earthquake sensor. When an earthquake causing acceleration occurs, the operation terminal receives the earthquake sensor activation information and disconnects the communication line. As a result, the controller cannot be operated from the operation terminal. Therefore, it is possible to prevent the automatic optical fiber connection switching device from operating erroneously when an earthquake occurs.

Also, the terminal information management method is provided at the end of the optical fiber for connection, which is one of the above optical fibers, in order to connect the optical fiber on the input side and the optical fiber on the output side via an adapter.

In this way, whether or not the input data can be used is examined based on the terminal information stored in advance in the management database, so when the input data is entered incorrectly, the connection of the optical fiber cord is switched. It is possible to prevent the operation from being executed. Further, when the connection switching operation is normally completed, the terminal information stored in the management database can be automatically updated with the input data. In addition, during the operation of the earthquake sensor, the terminal information stored in the management database based on the command execution information when the command is executed up to a predetermined sequence among the series of commands transmitted from the operation terminal to the controller Is updated. Thereby, even when an earthquake occurs, the connection switching operation and the terminal information can be managed in conjunction with each other.

Further, the terminal information management program causes a computer to execute each step in the terminal information management method according to claim 3 or claim 4 . With this configuration, the computer in which this program is installed can realize each function based on the program.

  According to the present invention, since the terminal information is automatically updated in conjunction with the optical fiber connection switching operation by the automatic optical fiber connection switching device, the terminal information can be easily managed. In addition, the reliability of maintenance management can be improved by backing up and restoring terminal information.

When the controller 30 acquires an operation signal from the earthquake sensor 17, the controller 30 transmits earthquake sensor activation information indicating that the earthquake sensor 17 has operated to the operation terminal 50.

  Next, the configuration of the operation terminal 50 will be described with reference to FIG. 2 (refer to FIG. 1 as appropriate). FIG. 2 is a block diagram showing the configuration of the operation terminal 50. The operation terminal 50 is for remotely operating the automatic optical fiber connection switching device 10, and includes a user interface unit 51, a management database 52, a management function module 53, a communication module 54, a test function module 55, and earthquake resistance control.

Next, management of terminal information associated with the optical fiber connection switching operation in the maintenance / operation system 1 of the automatic optical fiber connection switching device will be described with reference to FIG. FIG. 3 is a flowchart showing optical fiber connection switching by the operation terminal 50 and terminal information management processing associated therewith.
First, the operation terminal 50 displays a screen for selecting the automatic optical fiber connection switching device 10 to be controlled on the display unit 59 and accepts a selection input from the user (step 301). When the automatic optical fiber connection switching device 10 to be controlled is selected, the communication module 54 connects communication with the controller 30 that controls the automatic optical fiber connection switching device 10 (step 302).

Subsequently, the operation terminal 50 displays a screen for selecting an operation mode on the display unit 59, and accepts an operation mode input from the user (step 303). Here, there are three types of operation modes: connection mode, disconnection mode, and exchange mode.
The “connection mode” is an operation mode in which the optical jumper cord 11 is newly laid. In this mode, the automatic optical fiber connection switching device 10 uses the optical jumper cord 11 in which the extra length is wound around the extra length storage cartridge 16 and the optical connector plug 20 is aligned with the arrangement board 13 as an adapter of the connection board 12. The operation of connecting to 21 is executed.
The “cut mode” is an operation mode in which the optical jumper cord 11 is removed. In this mode, the automatic optical fiber connection switching device 10 performs an operation of removing the optical connector plug 20 from the adapter 21 of the connection panel 12, winding the disconnected optical jumper cord 11, and aligning it with the alignment panel 13. To do.
The “exchange mode” is an operation mode for switching the connection of two sets of optical jumper cords 11 connected together. In this mode, the automatic optical fiber connection switching device 10 designates two sets of optical connector plugs 20 connected to the adapter 21, cancels the connection of the two sets of wirings, and switches between them to switch the optical connector plugs. By connecting 20 to the adapter 21, an operation of creating two new sets of wiring is executed.

  When the operation mode is selected in step 303 (YES), the operation terminal 50 displays a screen for inputting input data including the optical connector plug 20 and the adapter 21 to be switched on the display unit 59. The switching target input from the user is accepted (step 304). Subsequently, when the input data is input (step 304, YES), the management function module 53 refers to the management database 52 and determines whether or not the input optical connector plug 20 and adapter 21 combination can be used. Is discriminated (step 305).

  If it is determined in step 305 that the input optical connector plug 20 and adapter 21 combination cannot be used (NO in step 305), the operation terminal 50 displays an error display indicating that it cannot be used. After displaying on the unit 59 (step 311), the processing returns to step 303. On the other hand, if it is determined that the combination can be used (step 305, YES), the management function module 53 uses the optical connector input as a switching target in step 304 based on the terminal information stored in the management database 52. A wiring route between the plug 20 and the adapter 21 is calculated (step 306), and a drive command (transmission data) for instructing a connection switching operation is created from the calculated wiring route. Then, the operation terminal 50 transmits a drive command (transmission data) to the controller 30 under the control of the communication module 54 (step 307). Thereby, the automatic optical fiber connection switching device 10 executes the commanded connection switching operation.

  Here, the connection switching operation by the automatic optical fiber connection switching device 10 will be described. Of the three operation modes, the “disconnection mode” and “connection mode” operations will be described (see FIG. 1). For example, when the optical connector plug 20 of the optical jumper cord 11 is connected to the first adapter 21 (before change) of the connection panel 12, this optical jumper cord 11 is connected to the second adapter 21 (after change). Assuming the case of switching to connect.

First, the robot mechanism 14 is moved to the position of the first adapter 21 (before change) of the connection panel 12 by the moving mechanism of the robot mechanism 14 and holds the optical connector plug 20. Then, when the robot mechanism 14 moves, the optical connector plug 20 is removed from the first adapter 21 (before change) of the connection panel 12. Subsequently, the winding mechanism 15 winds up the optical jumper cord 11 from which the optical connector plug 20 is disconnected. At this time, the wound optical jumper cord 11 is pulled out from the rear surface of the alignment board 13 to the extra length storage cartridge 16 side and stored in the extra length storage cartridge 16, and the optical connector plug 20 is aligned with the alignment board 13. It is stored in the hole. As a result, the optical connector plug 20 is aligned with the alignment board 13, so that the robot mechanism 14 can grip the aligned optical connector plug 20 (the cutting mode).

  Next, the optical connector plug 20 of the optical jumper cord 11 once aligned with the alignment board 13 is grasped by the robot mechanism 14 and pulled out from the alignment board 13. Then, the robot mechanism 14 moves to the position of the second adapter 21 (after the change) of the connection board 12 and connects the optical connector plug 20 to the second adapter 21 (after the change). 11 connection switching work is completed (the connection mode). Note that the operation of the “exchange mode” can be realized by combining the operations of the “disconnection mode” and the “connection mode”.

  Again, returning to the flowchart of FIG. 3, the description will be continued. When the automatic optical fiber connection switching device 10 executes the connection switching operation based on step 307, the controller 30 transmits a response message to the operation terminal 50. On the other hand, the operation terminal 50 repeats the determination (step 308) until the response message is received from the controller 30 by the management function module 53. When the response message is received (YES in step 308), the operation terminal 50 Thus, it is determined whether or not the automatic optical fiber connection switching device 10 has successfully completed the connection switching operation (step 309). When it is determined by the management function module 53 that the connection switching operation has been normally completed (step 309, YES), the operation terminal 50 updates the terminal information stored in the management database 52 with the input data ( Step 310), the process ends. Thereby, the connection state (terminal information) when the connection switching operation is completed is stored in the management database 52.

  On the other hand, in step 309, when the management terminal module 53 determines that the connection switching operation has not been normally completed by the management function module 53 (step 309, NO), an error indicating that the connection switching has not been completed. After the display is displayed on the display unit 59 (step 312), a screen for selecting retry or end of the connection switching operation is displayed, and an input is received (step 313). In step 313, when an input for selecting retry of the connection switching operation is made, the process returns to step 303. On the other hand, when an input for selecting end is made, the process is ended.

  Next, maintenance of the management database 52 of the operation terminal 50 in the maintenance / operation system 1 of the automatic optical fiber connection switching device will be described with reference to FIG. FIG. 4 is a flowchart showing maintenance processing of the management database 52 by the operation terminal 50. When a work command is input via the user interface unit 51, the operation terminal 50 reads the input work command by the management function module 53 (step 401). There are four types of work orders, for example, registration, update, backup, and restore. The operation terminal 50 determines the operation mode by the management function module 53 according to the read work instruction (step 402). If the operation mode is “registration”, the management function module 53 stores the input terminal information (input data) in the management database 52 (step 403).

  When the operation mode is “update”, the operation terminal 50 displays a selection screen as to whether or not to refer to the terminal information stored in the memory of the controller 30 by the management function module 53 and receives an input ( Step 404). When it is selected not to refer to the terminal information stored in the memory of the controller 30 (step 404, NO), the operation terminal 50 receives the terminal information stored in the management database 52 by the management function module 53. The (terminal information file) is updated with the input terminal information (input data) (step 409). On the other hand, when it is selected in step 404 to refer to the terminal information stored in the memory of the controller 30 (step 404, YES), the operation terminal 50 is connected to the controller 30 by the management function module 53. The communication line 40 is connected, terminal information (terminal information data) is read from the memory of the controller 30 (step 405), and the read terminal information (terminal information data) is displayed on the screen (step 406). Subsequently, a screen for selecting whether or not to execute the update is displayed and an input is received (step 407). When an input for executing the update is made (step 407, YES), the operation terminal 50 uses the management function module 53 to convert the terminal information stored in the management database 52 into the terminal information data (controller) displayed on the screen. The terminal information stored in the memory 30 is updated (step 408). Therefore, since the terminal information stored in the management database 52 of the operation terminal 50 is updated with the terminal information stored and recorded in the memory of the controller 30, even if the data is lost on the operation terminal 50 side, Update can be done without problems.

  When the operation mode is “backup”, the operation terminal 50 stores a backup of the terminal information (terminal information file) registered in the management database 52 in the backup unit 57 by the management function module 53 (step 410). . When the operation mode is “restore”, the operation terminal 50 reads the backup (terminal information file) of the terminal information stored in the backup unit 57 by the management function module 53 (step 411), and the storage command is given by the user. Is input (step 412, YES), the read terminal information is stored in the management database 52 (step 413).

  Next, the operation of the test function module 55 of the operation terminal 50 will be described with reference to FIG. FIG. 5 is an explanatory diagram for explaining the mechanism operation test mode controlled by the test function module 55 and the sensor state display mode. In the mechanism operation test mode, the robot mechanism 14 of the automatic optical fiber connection switching device 10, the moving mechanism for moving the robot mechanism 14, the scraping mechanism, the winding mechanism 15, and the operation (mechanism operation) of the cleaner mechanism 18 are defective.

The operation terminal 50 displays a mechanism operation test screen (overall test screen), an actuator individual drive control mode screen (individual test screen), and a sensor state display mode screen on the display unit 59.

  On the mechanism operation test screen, in order to test the mechanism operation of the entire apparatus, as shown in FIG. 5A, a power button 501, all actuator drive buttons 502, an origin return button 503, an offset operation button 504, and a cleaner operation are displayed. A button 505 and an encoder operation button 506 are provided. The power button 501 is for turning on / off the power supplied to each actuator and sensor. The all actuator drive button 502 is for turning ON / OFF the current applied to the actuator (motor). The origin return button 503 is to move each actuator to the set machine origin. The offset operation button 504 is used to move the XYZ axes (movement mechanism) in order to measure the state of the offset sensor that is a position sensor that measures the position information of the reference point provided on the connection panel 12. The cleaner operation button 505 is for performing a single operation of the cleaner mechanism such as winding of the cleaner tape and resetting of the tape counter. The encoder operation button 506 is for moving the idle roller 15b of the winding mechanism 15 to a designated position.

  In the individual drive control mode screen of the actuator, in order to execute an individual test of each actuator (motor), as shown in FIG. 5B, an XYZ axis motor button 507, a finger opening / closing motor button 508, and a scraping motor button 509 are displayed. , And a roller motor button 510 is provided. The XYZ axis motor button 507 is used for turning on / off each power source of the actuator for movement of the XYZ axis (movement mechanism), driving at a specified pulse amount, and registering motor acceleration / deceleration setting data for driving. The finger opening / closing motor button 508 is for turning on / off the supply current of the finger opening / closing actuator and moving it to the set finger opening position. The scraping motor button 509 is used to turn on / off the scraping arm rotation motor and move to a set arm position. The roller motor button 510 is for turning on / off the current supplied to the take-up actuator and driving the set amount of rotation.

  In the sensor status display mode screen, in order to monitor each sensor status during the operation of the actuator, as shown in FIG. 5C, an X, Y, Z-axis operation status button 511, a finger open / close status button 512, and a scraping are displayed. An arm status button 513, an offset position information button 514, a cleaner count button 515, an encoder count button 516, an overload detection status button 517, and an earthquake sensor status button 518 are provided.

  The X, Y, Z-axis operation state button 511 displays whether the XYZ-axis (movement mechanism) is the origin position or whether it is operating. The finger open / close state button 512 displays the opening position of the finger. The scraping arm state button 513 displays the position of the scraping arm. The offset position information button 514 displays position information measured by the offset operation. The cleaner count button 515 displays the cleaning count value after the reset. The encoder count button 516 displays the rotation amount of the take-up roller 15a. The overload detection state button 517 displays the state of the overload sensor. The earthquake sensor state button 518 displays the ON / OFF state of the earthquake sensor 17.

  According to the above configuration, the operation of the automatic optical fiber connection switching device 10 can be checked on the operation terminal 50 on the mechanism operation test screen or the individual drive control mode screen of the actuator. Note that the operation terminal 50 has encoder position setting information or cleaning position setting information for moving the idle roller 15b of the winding mechanism 15 to a specified position in order to wind the optical jumper cord 11 on the display unit 59, for example. It is also possible to display position information indicating a preset position such as. And operation which updates those position information can also be performed.

  Next, with reference to FIG. 6, the operation of the seismic control module 56 of the operation terminal 50 (see FIG. 2 as appropriate) will be described. FIG. 6 is a flowchart showing the processing of the seismic control module 56 when an earthquake of a scale in which the seismic sensor 17 operates occurs while a drive command is being sent from the operation terminal 50 to the controller 30.

  When an earthquake of a scale that the earthquake sensor 17 operates occurs, the controller 30 transmits earthquake sensor activation information to the operation terminal 50. When receiving the earthquake sensor activation information sent from the controller 30 (step 601, YES), the operation terminal 50 displays error information indicating that an earthquake has occurred on the display unit 59 (step 602) and the controller The communication line for transmitting the control signal to 30 is disconnected (step 603). Thereby, even if the operation terminal 50 is operated, it becomes impossible to control the controller 30.

  Before the communication line 40 is disconnected, the operation terminal 50 transmits a series of drive commands to the controller 30, and the controller 30 controls the automatic optical fiber connection switching device 10 according to the drive commands to switch the fiber connection. The action is executed. Then, the controller 30 returns the fiber connection switching status to the operation terminal 50 as a response message. Based on the response message, the operation terminal 50 creates and stores command execution information indicating to what sequence a series of drive commands are executed (step 604). Then, the operation terminal 50 updates the terminal information stored in the management database 52 to the current connection state based on the created command execution information (step 605).

  The operation terminal 50 determines whether or not a predetermined time has elapsed (step 606), and after the predetermined time has elapsed (step 606, YES), communicates an inquiry to the controller 30 (step 607). Based on the result of the inquiry, the operation terminal 50 determines whether or not the earthquake continues (step 608). If the earthquake has stopped (NO), the process at the time of occurrence of the earthquake ends. On the other hand, if the earthquake is continuing (YES), the process returns to step 606. In addition, when the process at the time of an earthquake occurrence is complete | finished, the communication of the drive command from the operating terminal 50 to the controller 30 shall be restored.

  An earthquake sensor 17 that operates at an acceleration equivalent to a seismic intensity of 5+ (250 gal) was installed, an automatic optical fiber connection switching device 10 was installed on the vibration test table, and an artificial seismic wave equivalent to a seismic intensity of 7 was input. However, the operation of the earthquake sensor 17 was confirmed, and it became impossible to control the controller 30 even if the operation terminal 50 was operated (the automatic optical fiber connection switching device 10 became uncontrollable). At this time, the terminal information in the management database 52 of the operation terminal 50 has been updated up to the point where the connection switching has been executed. For the optical connector plug 20 in which the connection switching has not been completed, information indicating that the connection switching has not been completed is present. Recorded.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment. For example, in the present embodiment, a description has been given assuming that one automatic optical fiber connection switching device 10 is controlled by one operation terminal 50, but there may be a plurality of units to be controlled. In this case, it becomes possible to centrally manage, for example, optical wirings on a plurality of floors in a building with a single operation terminal 50.
