Hereinafter, an embodiment according to the jumper switching construction support system of the present invention will be described in detail with reference to the drawings.
The jumper switching construction support system 10 according to the present embodiment is configured based on a work management terminal 20, a work instruction terminal 40, and a worker terminal 60.
The work management terminal 20 (hereinafter referred to as a management PC 20) creates a jumper switching management database (hereinafter referred to as a jumper switching management DB), outputs a jumper switching management table at a pre-operation stage, and rewrites the jumper switching management table. It plays a role of updating the jumper switching management DB associated with the specification change.

  The jumper switching management DB is created by wiring materials (visible table) sent from the requester of switching work of the telephone exchange, terminal position conversion table in the main wiring board (MDF), and list of persons in charge of construction at the switching work site. It is created based on data such as telephone office names. An example of the visible table is shown in FIG. 4, an example of the terminal position conversion table is shown in FIG. 5, and an example of the jumper switching management DB is shown in FIG.

  As shown in FIG. 2, the management PC 20 is basically configured to include a storage unit 24, a calculation unit 22, an output unit 28, an input unit 30, and the like. The storage means 24 is a large-capacity storage means such as a hard disk, and at least a visible table, a terminal position conversion table, a construction person list, jumper switching construction support software, database creation software (part of the functions of the jumper switching construction support software) ), Jumper switching management DB before construction (hereinafter referred to as JP switching management table (before work)), and jumper switching management table after construction (hereinafter referred to as JP switching management table (hereinafter referred to as “JP switching management table”). It is recommended that “after work”) be stored.

  The computing means 22 in this embodiment is a general term that combines a central processing unit (CPU) and a small-capacity storage means such as a memory. The calculation means 22 plays a role of reading various programs and data stored in the storage means 24 and performing various processes. For example, in the case of the present embodiment, the data required for creating the jumper switching management DB is a visible table, a terminal position conversion table, a construction staff name list, and a telephone office name. A program for creating the switching management DB is database creation software.

  The output unit 28 is a data writing unit or the like for a display, a printer, and a portable storage unit such as an FD, a CD, a DVD, and a nonvolatile memory. The display plays a role of displaying various data and the created jumper switching management DB as a visible state. The printer also plays a role of printing the content displayed on the display on a sheet. The data writing means plays a role of outputting data such as the created jumper switching management DB and jumper switching management table as data to the portable storage means.

  The input means 30 is a keyboard, a mouse, and a means for reading data stored in the portable storage means. The keyboard and mouse play a role of selecting icons and data displayed on the display and inputting characters and the like. The data reading means plays a role of enabling the data to be displayed on the display or stored in the storage means 24 by reading the data stored in the portable storage means.

  In the management PC 20 having such a basic configuration, the output means 28 and the input means 30 are connected to the storage means 24 and the calculation means 22 via the interface 26, and the storage means 24 and the calculation means 22 are connected to the interface 26. Data is exchanged via the bus 32. For example, when the database creation software icon displayed on the display is selected by the mouse, the calculation means 22 executes a process of reading a database creation program from the storage means 24. When the database creation software is activated by this process, for example, a display button for designating data and item names used to create a desired database is displayed on the display. Here, when a button is selected or a file name or item name of various data is input via the input unit 30, the calculation unit 22 reads various data from the storage unit 24 and creates a database by sorting the associated item names. .

  The JP switching management table (before work) is output by converting a table having the same contents as the created database (jumper switching management DB) into Excel data or the like, or the calculation means 22 is input from the jumper switching management DB. It is created by outputting data divided into construction units based on input information by means. The created JP switching management table (before work) is written to the portable storage means via the output means, and becomes data that can be used by the work instruction terminal 40 described later in detail.

  For the management PC 20 that performs such processing, a jumper switching management table after completion of the work is returned from a work instruction terminal 40 (referred to as a work PC 40), which will be described in detail later. The JP switching management table (after work) is returned as data input to the portable storage means, and the management PC 20 stores the data in the storage means 24 and executes an update for rewriting the jumper switching management DB.

  The work PC 40 is a personal computer arranged at the MDF jumper switching construction site and plays a role of giving work instructions to the worker (person in charge) at the construction site. As shown in FIG. 3, the work PC 40 includes a storage means 44, a calculation means 42, an output means 48, an input means 50, an interface 46, and a bus 52 as in the case of the management PC 20. 58, transmission means 54, and reception means 56 are basically provided.

  The storage means 44 includes a JP switching management table (before work) created by the management PC 20, a jumper switching construction result database (hereinafter referred to as construction result DB), jumper switching construction support software, database creation software (jumper switching construction). And a voice guidance software (may be a partial function of the jumper switching construction support software). Here, the construction performance DB is data edited by reflecting the construction performance based on the input JP switching management table (before work). Specifically, the name of the person in charge who performed the work, details of the work execution date and time, and the like are input. The roles and functions of the computing means 42, the output means 48, the input means 50, etc. are the same as those of the management PC 20 described above.

  The voice conversion means 58 is means for converting the data read from the construction performance DB into voice data, and may be an extension board for voice conversion. The transmission unit 54 is a unit for transmitting the data converted by the voice conversion unit 58 to the worker terminal 60 described later in detail, and is a generic name including an oscillator and an antenna.

  In the work PC 40 having such a configuration, the JP switching work management table (before work) stored in the portable storage means is read via the input means 50 and stored in the storage means 44. When the database creation software is activated via the input means 50 and necessary items are input, a construction performance DB is created based on the JP switching construction management table (before work) stored in the storage means 44 and stored in the storage means. Remembered.

  When the voice guidance software is activated after reading the construction result DB from the storage unit 44, the character data in the construction result DB is converted into voice data and transmitted to the worker terminal 60 via the transmission unit 54. Further, as will be described in detail later, a signal indicating completion of work or skipping work is transmitted from the worker terminal 60. When the reception means 56 receives a signal (data) indicating the progress of work, the voice guidance software advances the voice guidance in accordance with the received signal. For example, after transmitting the voice guidance data, if a signal indicating that the work in accordance with the transmitted voice guidance is completed is received, the voice guidance data corresponding to the next work is transmitted. On the other hand, after transmitting voice guidance data, if a signal indicating that the work in accordance with the transmitted voice guidance is skipped (skip) is received, the work can proceed without being affected by the transmitted voice guidance data Send voice guidance data for.

  The worker terminal 60 is a terminal based on a receiver 62 and a remote controller 68. The receiver 62 plays a role of receiving voice guidance data transmitted from the work PC and outputting it as voice that can be heard by the worker. For this reason, the receiver 62 includes at least a receiving unit 64 for receiving voice guidance data and a speaker (output unit 66) for outputting the received voice guidance data. In addition, the remote control 68 indicates that the work is completed after the worker has performed the work transmitted by the receiver 62, or that the work cannot be performed for some reason and the instruction work is skipped (skip). It plays a role of transmitting to the work PC 40. For this reason, the remote control 68 includes at least input means 72 for inputting that the work is completed or that the work is to be skipped, and a transmission means 70 for transmitting a signal indicating that the work has been input to the work PC 40 as data. It is done.

  In the worker terminal 60 having such a basic configuration, the receiver 62 outputs the voice guidance data transmitted from the work PC 40 as voice. When a signal indicating completion of work or skipping is input via the input means 72 of the remote control 68, a signal matching the information input from the transmission means 70 of the remote control 68 to the work PC 40 is transmitted.

  Next, a flow of data management by the jumper line switching construction support system 10 according to the present embodiment will be described with reference to FIG. First, the jumper switching work support software is activated on the management PC 20. When the jumper switching construction support software is activated, a window as shown in FIG. 8, for example, is displayed on the display. Here, of the two buttons shown as the activation mode, the “data management mode” button is a mode for mainly reading data necessary for creating the jumper switching management DB and the like. On the other hand, the “construction result management mode” button is a mode for inputting data associated with actual construction. The telephone office selection field is a field for selecting a telephone office that owns the exchange to be constructed, and the user name selection field is a field for selecting a user name to log in.

  When the “data management mode” button is selected, a window shown in FIG. 9 is displayed. As the first step, the “Visible Table Import” button in the “Pre-Work Process” item is selected, and the visible table sent from the customer is read. The read visible table data is stored in a database configured as a jumper switching management DB (master) in the storage means 24 (step 10). Next, the “Import terminal position conversion table” button in the “Pre-processing” item is selected to read the terminal position conversion table. The read terminal position conversion table is stored in a database configured as a terminal position conversion table in the storage means (step 20). After reading the visible table and the terminal position conversion table, select the “JP switch management DB creation” button in the “Pre-processing” item to create the jumper switch management DB. The jumper switching management DB is created by combining the visible table and the terminal position conversion table (step 30).

  After creating the jumper switching management DB, select the “Create JP switching management (for work) Excel” button in the “JP switching management (work) input / output” item to create the jumper switching management table (before work) ( Step 40).

  Next, the work PC 40 reads the JP switching management table (before work) created by the management PC 20. To read the JP switching management table (before work) in the work PC 40, start the jumper switching construction support software, select "construction result management mode", and in the window as shown in FIG. 10, "JP switching management (for work)" This is performed by selecting a “JP switch management (work) Excel import” button in the “E” item (step 50). The read data of the JP switching management table (before work) is stored in the construction result DB in the storage means 44 (step 60).

After the construction result DB is created, various conditions are input to output a work instruction by voice to the worker terminal 60 and record the work result by the worker (step 70).
After the completion of the jumper switching work, a JP switching management table (after work) reflecting the recorded work results is created. The JP switch management table (after work) is created by outputting the construction result DB data to an Excel file (step 80).

  The JP switching management table (after work) created by the work PC 40 is read by the management PC 20 and the jumper switch management DB is updated. The update of the jumper switching management DB is performed by importing “JP switching management (work) Excel” in the “JP switching management (work) input / output” item in the “data management mode” of the jumper switching construction support software started on the management PC 20. "" Button is selected (step 90).

  FIG. 11 shows the relationship between the MDF 80 to be constructed, the telephone exchange connected to the V-side terminal board 82 in the MDF 80, the subscriber telephone connected to the H-side terminal board 84, and the state of jumper switching construction in the MDF 80. FIG.

  As shown in FIG. 11, the switching operation is performed on the V-side terminal board 82 in the MDF 80 in a state where both the old exchange and the new exchange are connected. This is because the subscriber telephone can be used even during the switching work period. The old exchange is removed after the jumper switching operation is completed. A subscriber telephone or the like is connected to the H-side terminal board 84 in the MDF 80.

  The MDF 80 in such a connection form has a very large scale. For this reason, in the case of the embodiment, the worker A is in charge of the work of the V-side terminal board 82, the worker B is in charge of the work of the H-side terminal board 84, and the new accommodation is possible only on the V-side terminal board 82 side. Two workers are in charge of the old accommodation, and the work PC 40 performs work while transmitting voice guidance data to each worker terminal 60.

FIG. 12 shows a flow of jumper switching construction using the jumper switching construction support system according to the embodiment, and each step will be described.
First, the jumper switching construction support software is activated on the work PC 40, and the “construction result management mode” is selected. In the construction performance management mode window shown in FIG. 10, an operation to be performed is selected from the “construction performance management” item. The work to be selected includes laying work, auxiliary line work, continuity test, removal work, etc., buttons for each work ("laying work result management" button, "attached line work result management" button By selecting one of the “continuity test result management” button and “removal work result management” button, it is possible to select the construction to be executed (step 100). In addition, normal jumper switching work is executed in the order of laying work, additional work, and continuity test. When changing a completed jumper, it is executed in the order of removal work, laying work, additional work, and continuity test.

  In the window shown in FIG. 10, for example, when a “laying construction result management” button is selected, an input screen for various conditions is displayed, and a work target, work classification, work person in charge, and the like are entered. Here, the work target is an item for selecting the purpose of the work, such as whether it is a normal work or a security-related work. The work category is an item for selecting whether the corresponding work is a new work or a rework work. Further, the person in charge of work is an item for selecting the person in charge (worker) of the H-side terminal board 84 and the person in charge (worker) of the V-side terminal board 82, respectively. After selecting or inputting various information, selecting a start of work, for example, selecting a “start work” button (not shown), information on the laying target jumper is displayed on the display, and voice to the worker is displayed. Guidance is started (step 110).

  In the laying work, an operator of the H-side terminal board 84 is guided to the trunk line number of the laying jumper line, and an operator of the V-side terminal board 82 is guided to the new accommodation number of the laying jumper line. The worker of the H-side terminal board 84 and the worker of the V-side terminal board 82 perform the jumper laying work in accordance with the respective guidance (step 120). The person in charge (worker) who has finished the work inputs the work completion “OK” or “SKIP” to skip the work with the remote control 68 and transmits it to the work PC 40. In the work PC 40, the work result input by the remote controller is reflected in the construction result DB in real time (step 130).

  Next, the work PC 40 searches for information on jumper lines to be worked. If there is no information on the jumper line to be worked as a result of the search, the laying work is completed, and if there is information on the jumper line to be worked, the process proceeds to the voice guidance to the worker shown in step 120. (Step 140).

  After completing the laying work in this way, the “Attached Line Work Results Management” button is selected to start the attached line work. Similarly, in the line construction, input the various condition input screen displayed by selecting the “Attachment Line Performance Management” button, start the voice guidance by selecting the “Start Work” button, and work according to the voice guidance. I do.

  Since the wiring work is performed on the H-side terminal board 84, the voice guidance is performed only for the operator of the H-side terminal board 84. In the voice guidance, the H-side trunk line number is instructed, and the operator of the H-side terminal board 84 confirms the state of the line to which the jumper is attached using the auxiliary tester, and transmits the result by the remote controller 68. Examples of the line status test result include “vacant”, “busy”, “reverse idle”, and “reverse call”. Note that these test results are also recorded in the construction performance DB when they are transmitted to the work PC 40.

  When the result of the state test is “vacant” or “reverse vacant”, the worker performs the installation work of the target jumper line, and transmits the result to the work PC 40 by the remote controller 68. The result of the supplementary line work transmitted to the work PC 40 is recorded in the construction result DB, and the voice guidance is finished when the construction results of all the target lines are recorded.

  When the “Continuity Test Results Management” button is selected after the completion of the wiring work, the input screen for various conditions is displayed in the same way as the laying work and the wiring work described above, and the former containment worker (person in charge) conducting the continuity test The voice guidance is started by inputting the new containment worker (person in charge) and selecting the “start work” button.

  Each worker conducted the continuity test of the target jumper using the continuity tester according to the voice guidance, and the results such as “OK”, “NG”, “SKIP”, etc. were transmitted to the work PC 40 by the remote control 68. The result is recorded in the construction performance DB. When the test results of all the target lines are recorded, the voice guidance is finished. Note that laying and reworking may be reworked based on the results recorded in the construction performance DB.

  Finally, when selecting the “Removal work management” button and entering various conditions and selecting the “Start work” button, the operator of the H-side terminal board 84 will receive the trunk number of the jumper line to be removed, V The operator of the side terminal board 82 is informed of the new accommodation number of the jumper wire to be removed. Each worker performs the work of removing the target jumper line according to the voice guidance, and transmits the construction result to the work PC 40 by the remote control 68. In the work PC 40, the received work result is recorded in the work result DB in the same manner as each work described above. Then, when the construction results of all the target lines are recorded, the voice guidance for the removal work is finished.

  With the above-described configuration, the jumper switching construction support system 10 that supports construction as described above requires only a work PC 40 and a worker terminal 60 as the equipment to be used for each construction and is not installed. Can be used repeatedly at other construction sites. For this reason, compared with the technique currently disclosed by patent document 1 and patent document 2, the increase in a construction cost can be suppressed significantly. In addition, since the work PC 40 is responsible for reading and recording a large amount of material, it is possible to eliminate human errors such as misreading, skipping, and misunderstanding, and it is possible to reduce time and effort for correcting and recording material.

  In the above embodiment, the CSV format data is described as an Excel file, etc., but the difference between these file formats and storage formats does not affect the effects of the present invention. .
