[First Embodiment]
FIG. 1 is a block diagram showing a functional configuration of a connector identification system according to the first embodiment of the present invention. 1 includes an RFID tag 10, a database (DB) 20, an RFID reader / writer 30, a video camera 40, a CRT (Cathode Ray Tube) 50, a PC (Personal Computer) 60, and an operation input unit 70 such as a keyboard. It comprises.

  The RFID tag 10 is attached to the tip of the connector 100. The RFID tag 10 includes a light emitting element 11 such as an LED (Light Emitted Diode). A serial number that can identify the connector 100 is recorded in the RFID tag 10 in advance.

The database 20, the RFID reader / writer 30, the video camera 40, the CRT 50, and the operation input unit 70 are connected to the PC 60.
The PC 60 receives a user instruction from the operation input unit 70. The user inputs information such as facility information and customer information to the operation input unit 70. Here, the facility information is information indicating the date of manufacture of the connector 100, the manufacturing company, and the like, and the customer information is information indicating the service type, the customer name, and the like. The PC 60 reads the serial number stored in the database 20 based on an instruction from the operation input unit 70. The database 20 stores facility information, customer information, etc., and serial numbers in association with each other.

Further, the PC 60 outputs the serial number read from the database 20 to the RFID reader / writer 30. The RFID reader / writer 30 modulates radio waves in the radio frequency band with the serial number from the PC 60 and irradiates the RFID tag 10 with the radio waves.
The RFID tag 10 causes the light emitting element 11 to emit light when the serial number received via radio waves matches the serial number of the RFID tag 10 itself. The video camera 40 images the light emission state of the RFID tag 10 and outputs video data to the PC 60.

The PC 60 performs predetermined processing on the video data from the video camera 40 and then displays the video on the CRT 50.
FIG. 2 is a schematic diagram showing the configuration of the RFID tag 10 according to the first embodiment of the present invention. The RFID tag 10 in FIG. 2 includes a light emitting element 11, an RFID chip 12, and a receiving antenna 13.

  The receiving antenna 13 is formed in a loop shape within the RFID tag 10. When receiving the radio wave from the RFID reader / writer 30, the reception antenna 13 transmits a reception signal to the RFID chip 12. Further, the receiving antenna 13 can cause electromagnetic induction by radio waves from the RFID reader / writer 30 and supply power to the RFID chip 12.

FIG. 3 is a block diagram showing a functional configuration of the RFID chip 12 according to the first embodiment of the present invention. The RFID chip 12 in FIG. 3 has functions of a serial reception unit 121, a determination unit 122, a storage unit 123, and an LED activation unit 124.
The serial reception unit 121 receives the serial number transmitted via the radio wave and transfers the serial number to the determination unit 122.

The storage unit 123 stores in advance a unique serial number that can be specified by the connector 100. The storage unit 123 outputs the unique serial number to the determination unit 122 in response to an instruction from the determination unit 122.
When the determination unit 122 receives the serial number from the serial reception unit 121, the determination unit 122 instructs the storage unit 123 to return the unique serial number. The determination unit 122 compares the serial number from the serial reception unit 121 and the unique serial number from the recording unit 123, and determines whether these serial numbers match. When these serial numbers match, the determination unit 122 outputs a match notification to the LED activation unit 124.

  When at least one of facility information and customer information is input via the external input IF 65, the search unit 61 searches for facility information, customer information, and a serial number corresponding to the input information. The search unit 61 transfers the input information to the database 20 via the DB transmission / reception IF 66 and makes the database 20 respond to the facility information, customer information, and serial number corresponding to the input information. Thereby, the facility information, customer information, and serial number designated by the input information are read from the database 20. The database 20 stores, for example, as shown in FIG. 4, a table 1 in which facility information and serial numbers are associated, and a table 2 in which customer information and serial numbers are associated.

  The search unit 61 outputs the serial number read from the database 20 to the RFID reader / writer 30 via the RFID reader / writer IF 67. Further, the search unit 61 outputs the facility information, customer information, and serial number read from the database 20 to the light emission recognition unit 64. The search unit 61 may output at least one of facility information and customer information to the light emission recognition unit 64.

  The video capture unit 62 captures video data captured by the video camera 40 via the video camera IF 68. The video capturing unit 62 outputs the video data to the light emission recognition unit 64. In addition, the video capturing unit 62 outputs video data to the video processing unit 63 when a recognition notification is received from the light emission recognition unit 64.

  The light emission recognition unit 64 performs image analysis on the video data from the video capture unit 62 and determines whether or not there is light emission by the light emitting element in the video. When the light emission recognition unit 64 recognizes the light emission, the light emission recognition unit 64 determines that there is light emission by the light emitting element, and outputs a recognition notification to the video capturing unit 62. Further, when the light emission recognition unit 64 recognizes the light emission, the light emission recognition unit 64 outputs the facility information, the customer information, and the serial number to the video processing unit 63. At this time, the light emission recognizing unit 64 issues an instruction regarding the display position to the video processing unit 63 so that these pieces of information are displayed in accordance with the light emission position in the video. Note that the light emission recognition unit 64 may output at least one of the facility information and customer information to the video processing unit 63.

  The video processing unit 63 processes the video data from the video capturing unit 62 so that information from the light emission recognition unit 64 is displayed at a position designated by the light emission recognition unit 64. The video processing unit 63 outputs the processed video to the CRT 50 via the CRT IF 69. FIG. 5 is a schematic diagram showing a display example of the CRT 50. When the light emitting element 11 emits light, the CRT 50 displays the serial number of the connector 100, the manufacturing date and manufacturing company as equipment information, the service type and customer name as customer information.

  Next, the operation in the above configuration will be described. Here, as shown in FIG. 6, connectors 100-1 to 100-4 are attached to the optical fiber on the optical splitter 200 side, and connectors 100-5 and 100-2 on the drop fiber side are attached to the connectors 100-1 and 100-2. The case where 100-6 is respectively connected is demonstrated. RFID tags 10-1 to 10-6 are attached to the connectors 100-1 to 100-6, respectively.

FIG. 7 is a sequence diagram when the PC 60 according to the first embodiment of the present invention irradiates the RFID tags 10-1 to 10-6 with radio waves.
In FIG. 7, first, the user inputs at least one of facility information and customer information to be searched by the operation input unit 70. In FIG. 7, a case where a customer name as customer information is input will be described as an example.

  The external input IF 65 receives the customer name input by the user (S71). The external input IF 65 transfers this customer information to the search unit 61 (S72). The search unit 61 transmits the customer name to the database 20 via the DB transmission / reception IF 66 (S73) (S74).

  The database 20 reads the facility information, customer information, and serial number corresponding to the entered customer name with reference to Table 1 and Table 2. The database 20 returns these pieces of information to the search unit 61 via the DB transmission / reception IF 66 (S75) (S76). The search unit 61 outputs the serial number to the RFID reader / writer 30 via the RFID reader / writer IF 67 (S77) (S78). Further, the search unit 61 outputs the facility information, customer information, and serial number to the light emission recognition unit 64. Accordingly, the serial number is transmitted from the RFID reader / writer 30 to the RFID tags 10-1 to 10-6 by radio waves having RF.

FIG. 8 is a flowchart when the RFID chip 12 of the RFID tag 10-1 shown in FIG. 6 causes the light emitting element 11-1 to emit light.
First, the serial receiving unit 121 receives a serial number carried by radio waves from the RFID reader / writer 30 (S81). The serial reception unit 121 transfers the serial number to the determination unit 122.

  The determination unit 122 determines whether the serial number from the serial reception unit 121 matches the unique serial number stored in the recording unit 123 (S82). If these serial numbers match (Yes in S82), the determination unit 122 outputs a match notification to the LED activation unit 124.

Upon receiving the coincidence notification from the determination unit 122, the LED activation unit 124 causes the light emitting element 11-1 to emit light (S83), and the process ends.
If the serial numbers do not match in S82 (No in S82), the process ends.
Thereby, the light emitting element 11-1 of the RFID tag 10-1 attached to the connector 100-1 emits light.

FIG. 9 is a sequence diagram when displaying information of the connector 100-1 on the CRT 50.
The video camera 40 always images the connectors 100-1 to 100-6 and outputs the video data to the PC 60.
The video camera IF 68 receives the video data captured by the video camera (S91). The video camera IF 68 transfers this video data to the video capture unit 62 (S92). The video capture unit 62 transfers the video data from the video camera IF 68 to the light emission recognition unit 64 (S93).

  The light emission recognition unit 64 performs image analysis on the video data from the video capture unit 62, and determines whether or not there is light emission from the light emitting elements 11-1 to 11-6 in the video data. When the light emission recognition unit 64 recognizes the light emission of the light emitting element 11-1, the light emission recognition unit 64 outputs a recognition notification to the video capturing unit 62 (S94). In addition, when the light emission recognition unit 64 recognizes the light emission of the light emitting element 11-1, the facility information, customer information, and serial number output from the search unit 61 are output to the video processing unit 63 and the light emitting element 11- The video processing unit 63 is instructed to display such information at the position 1 (S95).

  The video capturing unit 62 outputs video data to the video processing unit 63 in response to the recognition notification from the light emission recognition unit 64 (S96). The video processing unit 63 generates a processed video in which the above information is displayed on the video data from the video capturing unit 62, and outputs the processed video to the CRT 50 via the CRT IF 69 (S97) (S98).

FIG. 10 is a schematic diagram showing a display example of the CRT 50. When the light emitting element 11-1 emits light, the CRT 50 displays the serial number of the connector 100-1, the date of manufacture and manufacturing company as equipment information, the service type and customer name as customer information.
As described above, in the first embodiment, the RFID tag 10 stores in advance a unique serial number that can identify the connector 100. The RFID tag 10 issues the light emitting element 11 when the serial number conveyed by the RFID reader / writer 30 matches the unique serial number. For this reason, especially when there are a plurality of connectors in a very narrow range such as an aerial optical closure, only a corresponding RFID tag emits light while a large number of optical fibers are accommodated. Thereby, the worker can find the connector to be worked from a plurality of connectors very easily. In addition, it is possible not only to avoid accidentally disconnecting another connector, but also to inadvertently cause loss to the communicating optical fiber when searching for an RFID tag. It becomes possible. That is, the possibility of affecting communication is reduced. Furthermore, the connector identification system according to the present embodiment can recognize the position of the cord with the light emitting position even when the relative position of the connector in the aerial optical closure is not fixed. Therefore, it can be used in many scenes.

In the first embodiment, the connector serial number, facility information, and customer information are displayed at the display position of the light emitting element on the CRT. Thereby, the connector identification system can display highly accurate information.
In the first embodiment, the light emission recognition unit 64 recognizes the light emission of the light emitting element 11 mounted on the RFID tag 10 to identify the connector. Accordingly, the corresponding connector can be easily detected based on the video data, and the video data captured by the video camera 40 can be extremely easily processed on the PC 60. Therefore, the required specifications for the PC 60 can be relaxed.

  Moreover, in the said 1st Embodiment, the system which displays an image | video on CRT50 with the light emission position as a trigger is employ | adopted. Thus, in the connector identification system according to the present embodiment, the relative position and coordinates of the connector in the aerial closure are shown, and further, a marker or the like necessary for general image recognition is not required. Becomes easy.

  In the first embodiment, power is supplied to the RFID chip 12 by electromagnetic induction generated by the receiving antenna 13. This makes it possible to cause the light emitting element 11 to emit light using radio waves from the RFID reader / writer 30, so that it is not necessary to place a battery on the RFID tag 10. For this reason, the RFID tag 10 can be manufactured at a lower cost than when a battery is placed. In addition, since it is not necessary to consider battery discharge or the like, the RFID tag 10 can be expected to be used for a longer period of time.

  When the facility information 1, 2, customer information 1, 2 and serial number 1, 2 are returned from the database 20, the search unit 610 retrieves the serial number 1, 2 through the RFID reader / writer IF 67 and the RFID reader / writer. Output to 30. In addition, the search unit 610 outputs the facility information 1, 2, customer information 1, 2 and serial numbers 1, 2 from the database 20 to the light emission recognition unit 612. The search unit 610 may output at least one of the facility information and the customer information to the light emission recognition unit 612.

  The light emission recognition unit 612 performs image analysis on the video data from the video capture unit 62 and determines whether or not there is light emission from the light emitting element in the video. When the light emission recognition unit 612 recognizes the light emission, the light emission recognition unit 612 determines that there is light emission by the light emitting element, and outputs a recognition notification to the video capturing unit 62.

  In addition, the light emission recognition unit 612 determines the connector type of the connector according to the number of light emission of the light emitting element. For example, if the light emission recognition unit 612 recognizes that three light emitting elements emit light, the light emission recognition unit 612 determines that the connector type of the connector is a socket. When the light emission recognition unit 612 recognizes that one light emitting element emits light, the light emission recognition unit 612 determines that the connector type of the connector is a plug.

  When the light emission recognition unit 612 recognizes the light emission, it outputs the facility information 1, 2, customer information 1, 2, and serial numbers 1, 2 to the video processing unit 611. At this time, the light emission recognition unit 612 issues an instruction to the video processing unit 611 so as to display the facility information 1, the customer information 1, and the serial number 1 at a position corresponding to the connector whose connector type is a socket. In addition, the light emission recognition unit 612 instructs the video processing unit 611 to display the facility information 2, the customer information 2, and the serial number 2 at a position corresponding to the connector whose connector type is a plug. Note that the light emission recognition unit 612 may output at least one of facility information and customer information to the video processing unit 611.

The video processing unit 611 processes the video data from the video capture unit 62 so that information from the light emission recognition unit 612 is displayed at a position designated by the light emission recognition unit 612. The video processing unit 611 outputs the processed video to the CRT 50 via the CRT IF 69.
Next, the operation in the above configuration will be described. Here, as shown in FIG. 13, connectors 100-1 to 100-4 are attached to the optical fiber on the optical splitter 200 side, and connectors 100-5 and 100-5 on the drop fiber side are attached to the connectors 100-1 and 100-2. The case where 100-6 is respectively connected is demonstrated. RFID tags 10-1 to 10-6 are attached to the connectors 100-1 to 100-6, respectively.

FIG. 14 is a sequence diagram when the PC 60 according to the second embodiment of the present invention radiates radio waves to the RFID tags 10-1 to 10-6.
In FIG. 14, first, the user inputs at least one of facility information and customer information to be searched by the operation input unit 70. Here, in FIG. 7, a case where a customer name as customer information is input will be described as an example.

  The external input IF 65 receives the customer name input by the user (S141). The external input IF 65 transfers this customer name to the search unit 610 (S142). The search unit 610 transmits the customer name to the database 20 via the DB transmission / reception IF 66 (S143) (S144).

  The database 20 reads the facility information 1, 2, customer information 1, 2 and serial numbers 1, 2 corresponding to the input customer name with reference to the tables 1 and 2. Here, the information regarding the connector whose connector type is socket is facility information 1, customer information 1 and serial number 1, and the information regarding the connector whose connector type is plug is facility information 2, customer information 2 and serial number 2. And

  The database 20 returns these pieces of information via the DB transmission / reception IF 66 (S145) to the search unit 610 (S146). The search unit 610 outputs the serial numbers 1 and 2 to the RFID reader / writer 30 via the RFID reader / writer IF 67 (S147) (S148). Further, the search unit 610 outputs the facility information 1, 2, customer information 1, 2 and serial numbers 1, 2 to the light emission recognition unit 612. Thus, serial numbers 1 and 2 are transmitted from the RFID reader / writer 30 to the RFID tags 10-1 to 10-6 by RF radio waves.

FIG. 15 illustrates a case where the RFID chip 12 of the RFID tag 10-1 illustrated in FIG. 13 causes the light emitting elements 111-1 to 113-1 to emit light, and the RFID chip 12 of the RFID tag 10-5 includes the light emitting element 111-5. It is a flowchart at the time of making it light-emit.
First, the serial receiving unit 121 receives a serial number carried by radio waves from the RFID reader / writer 30 (S151). The serial reception unit 121 transfers the serial number to the determination unit 122.

  The determination unit 122 determines whether or not the serial number from the serial reception unit 121 matches the unique serial number stored in the recording unit 125 (S152). When these serial numbers match (Yes in S152), the determination unit 122 outputs a match notification to the LED activation unit 126.

When the LED activation unit 126 receives the coincidence notification from the determination unit 122, the LED activation unit 126 causes the number of light emitting elements corresponding to the number of light emission from the storage unit 125 to emit light among the light emitting elements 111 to 113 (S153), and the process ends.
If the serial numbers do not match in S152 (No in S152), the process ends.

When the light emission recognition unit 612 recognizes the light emission of the light emitting elements 111-1 to 111-3 and 111-5, it outputs a recognition notification to the video capturing unit 62 (S <b> 164). The light emission recognition unit 612 determines that the connector type of the connector 100-1 to which the RFID 10-1 emitting light from the three light emitting elements is attached is a socket. The light emission recognition unit 612 determines that the connector type of the RFID tag 100-5 issued by one light emitting element is a plug.

  Further, when the light emission recognition unit 612 recognizes the light emission of the light emitting elements 111-1 to 113-1 and 111-5, the facility information 1, 2, customer information 1, 2, and serial number 1 received from the search unit 610. , 2 are output to the video processing unit 611. At this time, the light emission recognition unit 612 instructs the video processing unit 611 to display the facility information 1, the customer information 1 and the serial number 1 at the positions where the light emitting elements 111-1 to 113-1 emit light. put out. In addition, the light emission recognition unit 612 issues an instruction to the video processing unit 611 so as to display the facility information 2, the customer information 2, and the serial number 2 at a position where the light emitting element 111-5 emits light (S165).

  In response to the recognition notification from the light emission recognition unit 612, the video capture unit 62 outputs the video data to the video processing unit 611 (S166). The video processing unit 611 generates a processed video in which the above information is displayed on the video data from the video capturing unit 62, and outputs the processed video to the CRT 50 via the CRT IF 69 (S167) (S168).

  The determination unit 142 compares the serial number from the serial reception unit 141 with the unique serial number from the recording unit 143, and determines whether these serial numbers match (S252). When these serial numbers match (Yes in S252), the determination unit 142 outputs a match notification to the LED activation unit 144 and the speaker activation unit 145.

The LED activation unit 144 causes the light emitting element 11 to emit light in response to the coincidence notification from the determination unit 142. In addition, the speaker activation unit 145 causes the speaker 15 to generate a signal sound in response to the coincidence notification from the determination unit 142 (S253).

With the above configuration, the RFID tag 10 generates vibration in addition to light emission when the unique serial numbers match. Thereby, even if it is difficult to visually check, the operator can discriminate by vibration. Therefore, if the contact with the hand is possible, the worker can easily find the connector to be worked.
