The display unit 12 is provided, for example, above the housing 19 of the fusion splicer 2 (see FIG. 1), and displays the result of the self-diagnosis executed by the control processing unit 10.
[0020]
The memory unit 13 stores in advance various parameters related to the optical fiber connection function, such as a program memory 13A that stores in advance a self-diagnosis program and various programs related to the optical fiber connection function, and connection condition parameters and functional parameters. A parameter memory 13B, a connection data memory 13C for storing optical fiber connection data in advance, and a self-diagnosis result storage memory 13D for storing detailed data of the above-described self-diagnosis results.
[0021]
3 and 4 are flowcharts showing details of the self-diagnosis processing procedure by the control processing unit 10. First, the operator performs an input operation on the operation unit 11 to instruct the start of self-diagnosis processing.
[0022]
When the start of the self-diagnosis process is instructed, the machine information of the fusion splicer 2 such as the machine number and the software version used is recorded in the self-diagnosis result storage memory 13D (step 51 in FIG. 3). Subsequently, the self-diagnosis execution date and time information is recorded in the self-diagnosis result storage memory 13D (procedure 52).
[0023]
Next, the function of each part of the hardware of the fusion splicer 2, that is, the quality of operation, the presence / absence of a failure, etc. are inspected (procedure 53).

[0024]
Subsequently, the detailed data of the inspection result is recorded in the self-diagnosis result storage memory 13D (procedure 54). Then, the presence or absence of an error (defect) is determined from the inspection result (procedure 55). When it is determined that there is no error, the display unit indicates that the function of each hardware unit of the fusion splicer 2 is normal. 12 is displayed (procedure 56). On the other hand, when it is determined that there is an error, the display unit 12 displays that the function of each hardware unit of the fusion splicer 2 is abnormal (same procedure 57). At this time, the display unit 12 displays the trouble occurrence part and the recommended countermeasure according to the content.
[0025]
Then, the operator looks at the information on the display unit 12 and decides whether or not to continue the self-diagnosis process. When the self-diagnosis process is to be continued, the operation unit 11 instructs the start of the self-diagnosis process again. . Then, the processing after the procedure 51 is executed again.
[0026]
Next, it waits for the optical fiber to be connected to be set on the stage (not shown) of the fusion splicer 2 (procedure 58). When the optical fiber is set on the stage by the operator, the brightness of the LED of the illumination unit 17 is adjusted (same procedure 59). Subsequently, the drive mechanism 15 is controlled, and the optical fiber set on the stage is inserted into a predetermined fusion position (procedure 60). And the drive mechanism 15 is controlled and optical fibers are faced | matched (same procedure 61). Subsequently, the focus adjustment of the microscope in the image observation unit 18 is performed (same procedure 62).
[0027]
Next, it is determined whether or not the function inspection of the fusion splicer 2 before the optical fiber fusion (after the optical fiber setting) has been carried out (same procedure 63). The optical fiber is imaged, and the functions and operating states of the drive mechanism 15 and the image observation unit 18 before the optical fiber fusion are inspected based on the image data (procedure 64). Specifically, as shown in FIG. 5, the inspection contents include an optical fiber (stage) position / angle inspection, an optical system such as a microscope in the image observing unit 18 (lens breakage and focus availability). Etc.) Inspection, optical characteristic inspection, motor drive speed inspection of the drive mechanism 15 and the like. Then, according to the inspection result, the position adjustment of the microscope, the change of the motor driving speed, and the like are performed.
[0028]
Subsequently, the detailed data of the inspection result is recorded in the self-diagnosis result storage memory 13D (same procedure 65). At this time, together with the inspection result data, the type of the optical fiber is recorded in the self-diagnosis result storage memory 13D. Then, the presence / absence of an error is determined from the inspection result (same procedure 66). When it is determined that there is no error, the functions and operating states of the drive mechanism 15 and the image observation unit 18 before the optical fiber fusion are normal. A message to that effect is displayed on the display unit 12 (procedure 67). On the other hand, when it is determined that there is an error, the display unit 12 displays that the functions and operating states of the drive mechanism 15 and the image observation unit 18 before the fusion of the optical fiber are abnormal (same procedure 68). At this time, the display unit 12 displays the trouble occurrence part and the recommended countermeasure according to the content.
[0029]
Here too, the operator looks at the information on the display unit 12 and decides whether or not to continue the self-diagnosis. When the self-diagnosis is continued, the operation unit 11 instructs the start of the self-diagnosis process, and The process is executed from the beginning.
[0030]
Next, it is determined whether or not the discharge power is calibrated in the discharge unit 14 (same procedure 69). If calibration is not yet performed, the discharge power is calibrated (same procedure 70), and the above steps 58 to 63 are performed. Run repeatedly.
[0031]
Next, the discharge unit 14 is controlled to fuse and connect the optical fibers on the stage (procedure 71 in FIG. 4). And the connection part of each optical fiber is imaged by the image observation part 18, and the fusion splicing state of an optical fiber is test | inspected based on the image data (same procedure 72). Specifically, as shown in FIG. 5, the inspection contents include the discharge state of the discharge section 14 such as the number of discharges, the outer diameter deformation (thickness, thinning) of the optical fiber connection section due to the connection conditions, and bubbles. Examples include inspection of occurrence, shaft misalignment, and core deformation.
[0032]
Subsequently, the detailed data of the inspection result is recorded in the self-diagnosis result storage memory 13D (procedure 73). At this time, along with the inspection result data, information such as the calibrated discharge power, the number of discharges, and the end face angle of the optical fiber is recorded in the self-diagnosis result storage memory 13D. Then, the presence / absence of an error is determined from the inspection result (same procedure 74), and when it is determined that there is no error, the display unit 12 displays that the optical fiber connection state is normal (same procedure 75). . On the other hand, when it is determined that there is an error, the display unit 12 displays that the optical fiber connection state is abnormal (same procedure 76).
[0033]
Here too, the operator looks at the information on the display unit 12 and decides whether or not to continue the self-diagnosis. When the self-diagnosis is continued, the operation unit 11 instructs the start of the self-diagnosis process, and The process is executed from the beginning.
[0034]
As described above, the function inspection of each part of the hardware of the fusion splicer 2, the inspection of the function / operation state of the drive mechanism 15 and the image observation unit 18 before the optical fiber fusion, the optical fiber connection state after the optical fiber fusion By performing this inspection, it is possible to easily diagnose all the elements that affect the performance of the fusion splicer 2 and the elements related to the connection quality of the optical fiber.
[0035]
In the above processing, the three inspections are performed as a continuous flow, but each inspection may be performed independently. In this case, the operator performs an input operation on the operation unit 11 and gives an instruction to start each inspection.
[0036]
As shown in FIG. 6, the data management terminal 4 includes a data processing unit 20, an operation unit 21, a display unit 22, and a memory unit 23.
[0037]
The data processing unit 20 performs maintenance management processing for the fusion splicer 2. Specifically, the data related to the fusion splicer 2 (hereinafter simply referred to as fusion splicer data) stored in the memory unit 13 of the fusion splicer 2 is received, predetermined data processing is performed, and fusion splicing is performed. Processing for updating various parameters and programs stored in advance in the memory unit 13 of the connection device 2 is performed. As described above, the fusion splicer data includes detailed data of self-diagnosis results, optical fiber connection data, various parameters (see FIG. 8), and the like.
[0038]
The operation unit 21 instructs to take out the fusion splicer data, and selects parameter data and programs to be updated. The display unit 22 displays information such as fusion splicer data. The memory unit 23 stores management terminal software (see FIG. 8) such as an installer and a file creator in advance, and stores fusion splicer data fetched from the memory unit 13 of the fusion splicer 2.
[0039]
FIG. 7 is a flowchart showing details of the maintenance management processing procedure of the fusion splicer 2 by the data processing unit 20.
[0040]
In the figure, it is first determined whether or not to obtain fusion splicer data from the memory unit 13 of the fusion splicer 2 (procedure 81). This determination is performed based on an instruction input from the operation unit 21 or an instruction signal sent from the maintenance station management apparatus 8. When acquiring the fusion splicer data, a data output request signal is sent to the control processing unit 10 of the fusion splicer 2 (procedure 82). Thereafter, the fusion splicer data stored in the memory unit 13 of the fusion splicer 2 is received (procedure 83).
[0041]
Subsequently, it is determined whether or not the fusion splicer data is to be edited (procedure 84). When editing, the fusion splicer data received from the fusion splicer 2 or the fusion splicer already stored in the memory unit 23 is determined. The destination connection machine data is edited (procedure 85). Subsequently, a data file is created by fusing the fusion splicer data in a predetermined format (procedure 86). This filed data group is a standardized number, items, order, etc. of diagnostic contents in the detailed data of the self-diagnosis results. Subsequently, it is determined whether or not the fusion splicer data is to be stored (procedure 87), and when it is stored, the fusing splicer data filed is stored in the memory unit 23 (procedure 88).
[0042]
Next, it is determined whether or not the filed fusion splicer data is transmitted to the maintenance station management apparatus 8 (procedure 89), and when it is transmitted, as shown in FIG. The connection device data is transmitted to the maintenance station management apparatus 8 by a predetermined file transfer function (procedure 90). At this time, since the fusion splicer data is filed in a predetermined format, the data transfer procedure between the data processing unit 20 and the maintenance station management device 8 can be easily automated. The file transfer function can be used by providing a commercially available e-mail function. In this case, data transfer can be easily performed.
[0043]
In this manner, the data processing unit 20 can comprehensively manage the fusion splicer data from the fusion splicer 2.
[0044]
Thereafter, it is determined whether there is update parameter data or an update program sent from the maintenance station management apparatus 8 (procedure 91), and if there is such update parameter data or an update program, it is received (procedure 92). These are filed in the same format as described above.
[0045]
Next, it is determined whether or not the parameter or program stored in the memory unit 13 of the fusion splicer 2 is to be updated (procedure 93). When updating, either one or both of the update parameter data and the update program is performed. Is sent to the control processing unit 10 of the fusion splicer 2 and stored in the memory unit 13 (procedure 94). The update parameter data and update program at this time include those input by the operation unit 21 and those transmitted from the maintenance station management apparatus 8 (see FIG. 8).
[0046]
Next, it is determined whether or not the maintenance management process for the fusion splicer 2 has been completed (procedure 95). If the maintenance management process has not been completed, the process returns to the procedure 81 and the above process is repeatedly executed. On the other hand, when the maintenance management process is completed, the maintenance management result is displayed on the display unit 22 (procedure 96), and the maintenance management result is transmitted to the maintenance station management apparatus 8 (procedure 97).
[0047]
FIG. 9 is a flowchart showing details of the maintenance management processing procedure of the fusion splicer 2 by the maintenance station management device 8.
[0048]
In the figure, first, it is determined whether or not there is a data file sent from the data processing unit 20 of the data management terminal 4 (procedure 101). If there is such a data file, it is received and displayed on the display unit (not shown). (Procedure 102).
[0049]
Here, the maintenance manager in the maintenance station 6 analyzes the received data, grasps the problem of the fusion splicing operation of the fusion splicer 2, and determines the response. Specifically, it is determined whether to update the program stored in the program memory 13A of the fusion splicer 2 or the parameter stored in the parameter memory 13B. Select and input with an operation unit (not shown).
[0050]
Then, the maintenance station management device 8 determines whether or not the response to the fusion splicer 2 is a program update (procedure 103). When the program is updated, the selected update program is prepared (procedure 104). ). Subsequently, it is determined whether or not the update program is transmitted to the data management terminal 4 (procedure 105). When the update program is transmitted, the update program file is stored in the data processing unit 20 of the data management terminal 4 as shown in FIG. (Procedure 106).
[0051]
Next, it is determined whether or not the update parameter data is to be edited (procedure 107). When editing the data, the selected update parameter data is edited (procedure 108). Then, an update parameter data file in which the edited update parameter data is filed in the same format as described above is created (procedure 109). Subsequently, it is determined whether or not the update parameter data is to be transmitted to the data management terminal 4 (procedure 110). When the update parameter data is transmitted, the update parameter data file is stored in the data management terminal 4 as shown in FIG. The data is sent to the unit 20 (procedure 111).
[0052]
Thereafter, the maintenance management result sent from the data management terminal 4 is received (procedure 112). Then, it is determined whether or not the maintenance management process of the fusion splicer 2 has been completed (procedure 113). If the maintenance management process has not been completed, the process returns to the procedure 101 and the above process is repeatedly executed.
[0053]
Next, a method for performing maintenance management of the fusion splicer 2 in the maintenance management system 5 configured as described above will be described.
[0054]
First, a maintenance manager in the maintenance station 6 instructs the maintenance station management device 8 to take out the fusion splicer data. Then, the fusion splicer data including the detailed data of the latest self-diagnosis result stored in the memory unit 13 of the fusion splicer 2 is sent to the maintenance station management device 8 through the data management terminal 4, It is displayed on the display unit (not shown) of the maintenance station management device 8. The maintenance manager sees the detailed data of the self-diagnosis result and accurately grasps the situation such as whether or not a failure has occurred in the fusion splicing operation of the fusion splicer 2. At this time, by comparing the self-diagnosis result data sent from the fusion splicer 2 with the data left at the time of shipment from the factory, it is possible to know the change in the situation of the fusion splicer 2.
[0055]
If there is a defect in the fusion splicing operation of the fusion splicer 2, the maintenance manager determines a measure for the defect, transmits update parameter data to the fusion splicer 2, and connects the optical fiber. The parameter related to the function is changed or the update program is transmitted to the fusion splicer 2 to upgrade the software related to the optical fiber connection function. Also, if the fusion splicing operation has a minor problem, only a simple operation instruction may be given to the local worker. Thereby, the maintenance management service for the fusion splicer 2 at a remote location can be performed with sufficient contents.
[0056]
In addition, the fusion splicer 2 can be maintained and managed in the field. In this case, first, the operation unit 21 of the data management terminal 4 instructs to take out the fusion splicer data. Then, the fusion splicer data including the detailed data of the latest self-diagnosis result stored in the memory unit 13 of the fusion splicer 2 is displayed on the display unit 22 of the data management terminal 4. And based on the detailed data of the self-diagnosis result, the fusion splicer 2 is maintained and managed by the same method as described above.
[0057]
As described above, according to the present embodiment, detailed data when the optical fiber connection function of the fusion splicer 2 is self-diagnosed is stored in the memory unit 13 of the fusion splicer 2. The maintenance station 6 can also retrieve the detailed data of the self-diagnosis result whenever necessary. Accordingly, it is not necessary to operate the fusion splicer 2 one by one and reproduce the trouble situation one by one, as in the case where maintenance management of the fusion splicer 2 is performed based on the image data of the malfunction status of the fusion splicing operation. Thereby, maintenance and maintenance management of the fusion splicer 2 can be easily supported even from a remote place.
[0058]
Further, since the fusion splicer 2 is not particularly provided with a communication control device or the like for communicating with the maintenance station management device 8, the fusion splicer 2 is advantageous in terms of cost and size.
[0059]
FIG. 10 is a configuration diagram showing an embodiment of a fusion splicing device according to the present invention and another example of the maintenance management system thereof. In the figure, members that are the same as or equivalent to those shown in FIG.
[0060]
In the figure, a maintenance management system 30 enables maintenance / management of a plurality of fusion splicers 2 in, for example, a maintenance station 31 in an optical parts factory. Each fusion splicing device 1 is always connected to a maintenance station management device 33 via a network 32 such as a LAN.
[0061]
In such a maintenance management system 30, the maintenance station management device 33 monitors the state of each fusion splicer 2 constantly or periodically, so that recovery and maintenance when an abnormality occurs can be easily performed. Moreover, the parameter setting and software version upgrade of each fusion splicer 2 can be efficiently performed collectively. Further, as a result of self-diagnosis of the optical fiber connection function of the fusion splicer 2, when it is determined that there is some abnormality in the fusion splicer 2, the fact and the detailed data of the self-diagnosis result are notified to the maintenance station management device. 33 can be configured to automatically transmit to 33.
[0062]
The present invention is not limited to the above embodiment. For example, in the fusion splicing apparatus 1 of the above embodiment, the data management terminal 4 is always connected to the fusion splicer 2, but this is not a limitation, and the fusion splicer 2 is connected to the fusion splicer 2 only when necessary. You may make it acquire the detailed data when the data management terminal 4 is connected and the optical fiber connection function of the fusion splicer 2 is self-diagnosed.
