Abstract

PROBLEM TO BE SOLVED: To reduce the danger of erroneously recognizing a cable insertion port to be operated by an operator.SOLUTION: Each of cable insertion ports 104 arranged in a matrix on a distributing board 103 includes an LED lit when the cable insertion port is an operation target. In each of rows and columns where the cable insertion ports 104 are arranged, a visible light radiation unit 108 is disposed to illuminate the row or the column when the row does not include the operation target cable insertion port. An operation inhibition area is illuminated by the visible light output from the visible light radiation unit 108. In each of the rows and the columns, a laser 107 and a photodetector 109 are arranged to face each other.

Description

  The present invention relates to an erroneous work prevention technique for preventing erroneous connection and removal of cables in a cable housing device such as an optical termination.

  A cable housing device such as an optical termination has a socket connector (cable insertion port) into which a plug connector attached to the end of the cable is inserted. By inserting the plug connector into this cable insertion port, A cable is connected to the cable receiving device.

  By the way, when connecting a cable to a cable accommodating apparatus, generally, it is as follows. First, an operator confirms a cable insertion port for connecting a cable based on a design drawing and marks it with tape. Thereafter, the worker connects the connection target cable to the marked cable insertion port. Also, when a cable is removed from the cable housing device, the cable insertion port to which the cable to be removed is connected is marked with tape, and then the cable is removed from the marked cable insertion port.

  However, the above-described general connection / extraction method has a problem that it takes time and effort because the cable insertion port to be worked by the worker must be marked with tape.

  Therefore, in order to solve such a problem, a light emitting element is arranged in the vicinity of each cable insertion port, and the light emission arranged in the vicinity of the cable insertion port to be worked upon when connecting and disconnecting the cable is performed. There has been proposed a technique of causing an element to emit light (see, for example, Patent Documents 1 and 2).

However, since the techniques described in Patent Documents 1 and 2 only cause the light emitting elements arranged in the vicinity of the cable insertion port to be a work target to emit light, There is a risk of misrecognizing the mouth. For example, as shown in FIG. 12, when the light emitting element 100a for the cable insertion port 200a is caused to emit light, the cable insertion port 200b provided on the upper side is mistakenly recognized as the cable insertion port to be worked.

Otherwise, there is a possibility that there is an error in the updated contents. Have the instructor check the contents of the update instruction.

  Next, the operation of the present embodiment will be described in detail.

  Referring to FIG. 10, the work instructor of the management apparatus 2 creates work target optical termination information for the work to be performed this time (step S101).

  More specifically, the work instructor first inputs from the input unit 207 a floor drawing creation instruction including the floor ID of the floor on which the current work is performed. As a result, the control unit 202, based on the floor information recorded in association with the floor ID from the floor information storage unit 204, sets the installation position and optical termination frame of each optical termination frame installed on the floor. A floor diagram indicating the ID is created and displayed on the display unit 208. Thereafter, the worker determines an optical termination used in the work to be performed this time based on the floor drawing, and inputs a search instruction including the optical termination ID from the input unit 207. As a result, the control unit 202 retrieves the optical termination installation information recorded in association with the optical termination ID from the optical termination installation information storage unit 205 and displays it on the display unit 208.

  After that, when the work to be performed this time is a connection work, the work instructor determines a cable insertion port to be used in the current connection work from among the cable insertion holes whose mounting information is “unused”. Then, an input unit for creating a work target optical termination information including the cable insertion ID, the ID of the optical termination used in the current work already determined, and the work type “connection” Input from 207. Thereby, the control unit 202 creates work target optical termination information including the ID of the optical termination to be worked, the ID of the cable insertion port to be worked, and the work type “connection”. A unique work ID is generated together. Thereafter, both are associated and recorded in the work target optical termination information storage unit 206 and displayed on the display unit 208. On the other hand, when the work to be performed this time is an extraction work, a cable insertion port from which the optical cable is to be extracted is determined from the cable insertion ports whose mounting information is “unpluggable”, and the cable insertion port ID is determined. Then, from the input unit 207, an operation target optical termination creation instruction including the ID of the optical termination used in the current work already determined and the work type “extraction” is input. Thereby, the control unit 202 creates work target optical termination information including the ID of the optical termination to be worked, the ID of the cable insertion port to be worked, and the work type “removal”. And a unique work ID is generated. Thereafter, both are associated and recorded in the work target optical termination information storage unit 206 and displayed on the display unit 208. Further, the work instructor transmits the work ID to the portable terminal device of the worker who actually performs the work, and notifies the worker of the work ID.

  When the worker goes to the work site, first, using his / her portable terminal device, the worker transmits a work instruction request including a work ID for specifying the work to be performed this time to the management apparatus 2 (step S102). In addition, you may make it incorporate the work instruction request transmission means which transmits the work instruction request containing work ID to the management apparatus 2 in the optical termination.

  When the control unit 202 in the management apparatus 2 receives the work instruction request, the control unit 202 displays the optical termination ID, the cable outlet ID, and the work type information recorded in association with the work ID included in the work instruction request. Search from the termination information storage unit 206. Thereafter, the control unit 202 transmits a work instruction including the searched cable insertion port ID and work type information to the optical terminal indicated by the searched optical terminal ID (step S103). Now, for example, if the received work ID requesting work instruction is “SID1” and the content of the work target optical termination information storage unit 206 is as shown in FIG. A work instruction including a cable insertion port ID “A32, A35” and work type information “connection” is applied to an optical termination (with optical termination 1-1) having a rack ID “HID1”. Will be sent.

  When the control unit 121 in the optical termination 1-1 receives the work instruction via the network 3 and the transmission / reception unit 120, the control unit 121 performs the process of step S104. In step S <b> 104, the control unit 121 first instructs the lamp driving unit 127 to turn on the work location lamp 101. As a result, the lamp driving unit 127 lights the work location lamp 101 provided at the upper front of the housing of the optical termination 1-1, so that the worker can definitely select the optical termination to be worked on. Can be recognized.

  Next, the control unit 121 passes the cable insertion port ID “A32, A35” and the work type information “connection” included in the work instruction to the LED drive unit 124. Accordingly, as shown in FIG. 11, the LED driving unit 124 causes the LED 105 corresponding to the cable insertion port with the cable insertion port ID “A32, A35” to emit light according to the work type information “connection” ( For example, the light emission color is yellow). That is, the LED 105 arranged in the third row and second column and the LED 105 arranged in the third row and fifth column emit yellow light. As a result, the worker can connect the cable insertion port (the cable insertion port arranged in the third row, second column and the third row, fifth column) corresponding to the LED 105 that emits light to the work target. It can be recognized that the work type is “connection”.

  Thereafter, the control unit 121 gives the IDs “A32, A35” of the cable outlets to be worked, which are included in the work instructions, to the visible light drive unit 123, the laser drive unit 125, and the cutoff detection unit 126. hand over.

  As a result, the visible light driving unit 123 includes a row in which the cable insertion port 104 is arranged, a row in which the cable insertion port 104 to be operated is not arranged, among the visible light emitting units 108 corresponding to the respective columns. And the visible light radiation unit 108 corresponding to the column is driven. The driven visible light radiation unit 108 outputs visible light, and the cable insertion port to be operated is arranged in the row portion and the column portion where the cable insertion port on the wiring board 103 is arranged. Illuminate the row and column parts that are not done. Thereby, the worker can recognize the cable insertion port 104 that should not be a work target.

  Further, the laser driving unit 125 drives the laser 107 corresponding to the row and the column where the cable insertion port 104 to be worked is not arranged. Moreover, the interruption | blocking detection part 126 cannot receive the laser beam from the opposing laser 107 more than fixed time in the light receiving element 109 corresponding to the row | line | column and column which the cable insertion port 104 made into work object is not arrange | positioned. When it is detected that a light receiving element is present, a blockage detection notification is output to the control unit 121. Therefore, the laser beam can be received for a predetermined time or longer by blocking the laser beam by the operator's hand trying to insert the optical cable into the cable insertion port other than the cable insertion port that is the work target. When a light receiving element that has disappeared is generated, a shutoff detection notification is output from the shutoff detection unit 126 to the control unit 121. In response to this, the control unit 121 controls the speaker driving unit 128 to output a warning sound from the speaker 102. Is output, so that the worker can recognize that he or she is about to make a mistake. In addition, when a light receiving element that can no longer receive laser light is generated, a warning sound is not generated immediately, but when a light receiving element that has been unable to receive laser light for a predetermined time or longer is generated, a warning sound is generated. This is to prevent a warning sound from being emitted when the laser beam is interrupted for a short time by an optical cable or the like.

  Note that the processing performed in step S104 when the work type information included in the work instruction sent from the management apparatus 2 is “removal”, the LED drive unit 124 changes the light emission form of the LED 105 to the work type information. Is the same as that in the case where the work type information is “connected” except that the operation type is different from that in “connected” (for example, the emission color is orange).

  By performing the process of step S104, the work place lamp 101 of the optical termination rack to be worked is turned on, and the LED 105 corresponding to the cable insertion port to be worked is turned on in a light emission form corresponding to the work type. The work-prohibited portion (mask portion) is illuminated by the visible light output from the visible light emitting unit 108, and the warning sound generation region is set by the laser light output from the laser 107. After that, an operator performs an optical cable connection / extraction operation.

  First, the worker searches for an optical termination (for example, optical termination 1-1) for which the work location lamp 101 is lit and is a work target. Thereafter, the worker confirms the cable insertion port 104 to be worked on based on the lit LED 105 and the mask portion illuminated by visible light, and the work type is an optical cable based on the emission color of the LED 105. Check if it is a connection or removal. After that, if the work type is “connected”, the worker inserts the optical cable drawn in advance under the optical termination 1-1 into the work target cable insertion port 104. If the work type is “unplug”, the optical cable is removed from the cable insertion port 104 to be worked.

  At the time of work by the worker, the following processing is performed in the optical termination 1-1 (step S105).

  When connecting or disconnecting an optical cable, try to connect an optical cable to a cable insertion port other than the target cable insertion port, or remove an optical cable from a cable insertion port other than the target cable insertion port. When the light receiving element 109 that cannot receive the laser beam from the facing laser 107 by a worker's hand or the like is generated for a predetermined time or longer is generated, the cutoff detection unit 126 notifies the control unit 121 of the cutoff detection. In response to this, a warning sound generation process is performed in which the control unit 121 controls the speaker driving unit 128 to output a warning sound from the speaker 102 in response. This warning sound generation process can alert the worker. In addition, when an optical cable is connected to the cable insertion port 104, the removal detection unit 122 outputs a connection detection notification (including the ID of the cable insertion port to which the optical cable is connected) to the control unit 121, The control unit 121 performs a process of transmitting a connection notification including the ID of the self-lighted termination and the ID of the cable outlet notified by the connection detection notification to the management device 2. When the optical cable is removed from the cable insertion port 104, the removal detection unit 122 outputs a removal detection notification (including the ID of the cable insertion port from which the optical cable has been removed) to the control unit 121. A process is performed in which the control unit 121 transmits a removal notification including the ID of the self-lighted termination and the ID of the cable insertion port 104 notified by the removal detection notification to the management device 2. The above is the process performed in step S105.

  When the connection notification is sent from the optical termination 1-1, the control unit 202 of the management apparatus 2 displays it on the display unit 208 and is recorded in the optical termination mounting information storage unit 205. The mounting information recorded in association with the ID of the optical termination 1-1 and the ID of the cable outlet included in the connection notification is updated to “connection available”. . Further, when the removal notification is sent from the optical termination 1-1, it is displayed and the above removal notification in the mounting information recorded in the optical termination mounting information storage unit 205 is displayed. The mounting information recorded in association with the ID of the included optical termination 1-1 and the ID of the cable outlet is updated to “unused” (step S106).

  The work instructor of the management apparatus 2 sends the connection notification displayed on the display unit 208 and the corresponding work target optical termination information read from the work target optical termination information storage unit 206 (which was sent in step S102). When it is determined that the cable connection work in the optical termination 1-1 has been completed based on the work target optical termination information recorded in association with the work ID included in the work instruction request, the person in charge of the test Is instructed to perform a normality confirmation test of communication with END-TO-END for the optical cable that has been connected (step S107).

  If there is no problem in the test result, the work instructor sends information indicating the mounting information to be updated from the input unit 207 (the ID of the cable insertion port to which the optical cable is connected in the current connection work and the cable difference). An update instruction including the ID of the optical termination 1-1 having a slot and the updated content “in operation” is input. When an update instruction whose updated content is “in operation” is input, the control unit 202 first determines whether or not the mounting information to be updated is currently “connection available”. Check out. If “connection is available”, the corresponding mounting information is updated to “under implementation”. On the other hand, if “connection is not available”, there is a possibility that there is an error in the information indicating the update target in the update instruction, and this is displayed on the display unit 208 (step S108).

  In addition, the work instructor of the management device 2 determines that the cable removal work in the optical termination 1-1 has been completed based on the removal notification displayed on the display unit 208 and the corresponding work target optical termination information. Then, an update instruction including information indicating the mounting information to be updated from the input unit 207 and the updated content “unused” is input from the input unit 207. When an update request whose updated content is “unused” is input, the control unit 202 first determines whether or not the mounting information to be updated is currently “connection available”. If the connection information is “available for connection”, the corresponding implementation information is updated to “unused”. If it is not “available for connection”, the update target in the update instruction is indicated. Since there is a possibility that there is an error in the information, the fact is displayed on the display unit 208 (step S108).

  Thereafter, the work instructor of the management apparatus 2 inputs a work completion instruction from the input unit 207. This work completion instruction includes the ID of the optical termination 1-1 in which the optical cable connection and removal work has been completed. When the work completion notification is input, the control unit 202 transmits the work completion notification to the optical termination 1-1 (step S109).

  When receiving the work completion notification, the control unit 121 of the optical termination 1-1 instructs the visible light driving unit 123, the LED driving unit 124, the laser driving unit 125, and the lamp driving unit 127 to stop the driving operation. As a result, the visible light radiation unit 108, the LED 105, the laser 107, and the work location lamp 101 are turned off. Further, the stop detection unit 126 is instructed to stop the stop detection operation (step S110).

  In the above-described embodiment, the optical termination has been described as an example of the cable housing device, but the present invention is not limited to this.

[Effect of the first embodiment]
According to the present embodiment, it is possible to reduce the risk that a worker erroneously recognizes a cable insertion port to be worked. The reason is that the row and column where the cable outlets to be worked are not arranged are illuminated, and the visible ray emitting unit 108 that functions as a row and column illumination means that clearly indicates the work prohibited area on the wiring board 103 is provided. Because.

  In addition, the present embodiment includes a row / column cutoff detecting means composed of a laser 107 and a light receiving element 109 arranged to face each row and each column, and no cable insertion port to be operated is arranged. If any of the light receiving elements of the row or column corresponding to the row or column cannot receive the laser beam, an alarm is issued, so that the worker is likely to make a connection error or disconnection. You can call attention.

[Second embodiment of the present invention]
Next, a second embodiment of the present invention will be described. In the first embodiment described above, after confirming communication with the END-TO-END for the optical cable connected to the optical termination 1-1, the management device 2 performs an operation on the optical termination 1-1. A completion notice is transmitted to turn off all the LEDs 105 of the optical termination 1-1. On the other hand, the present embodiment is characterized in that the light emission form of the LED 105 corresponding to the cable insertion port to which the optical cable whose communication has been confirmed is connected is changed to one indicating “in operation”. Since the difference between the present embodiment and the first embodiment is the processing of step S109 and step S110 in FIG. 10, only this difference will be described below.

  The work instructor of the management apparatus 2 inputs a work completion instruction from the input unit 207 when the process of step S108 ends. This work completion instruction includes the ID of the optical termination 1-1 that has completed the optical cable connection work. When the operation completion instruction is input, the control unit 202 searches the optical termination mounting information storage unit 205 and records the cable outlet ID recorded in association with the ID of the optical termination 1-1. Then, the ID of the cable outlet whose mounting information is “in operation” is obtained. Thereafter, the control unit 202 transmits a work completion notification including the obtained ID to the optical termination 1-1 (step S109).

  When the control unit 121 in the optical termination 1-1 receives a work completion notification from the management device 2, the control unit 121 stops the driving operation for the visible light driving unit 123, the laser driving unit 125, and the lamp driving unit 127. In addition to instructing the interruption detection unit 126 to stop the detection operation. As a result, the visible light radiation unit 108 and the laser 107 included in the optical termination 1-1 are all turned off. Further, the control unit 121 passes the ID of the cable insertion port included in the work completion notification to the LED driving unit 124 and instructs to change the light emission form of the LED 105 to “in operation”. (For example, instructing the emission color to be green). Thereby, the LED driving unit 124 causes the LED 105 corresponding to the cable insertion port 104 indicated by the ID passed from the control unit 121 to emit light in green.

[Effect of the second embodiment]
According to this embodiment, in addition to the effects obtained in the first embodiment, the cable insertion port to which the optical cable in operation is connected is recognized based on the light emission form such as the light emission color of the LED. The effect that it becomes possible can be acquired. The reason is that in response to the work completion notification sent from the management device 2 including the ID of the cable insertion port to which the optical cable that has been confirmed to communicate in END-TO-END is connected, the ID This is because the light emission form of the LED corresponding to the cable insertion port indicated by is changed to one indicating “in operation”.

  The present invention can be applied to a cable housing device for housing a cable, such as an optical termination.
