Description

  The present invention relates to a connector plug and a connector adapter to which the plug is connected, and in particular, a connector insertion / removal management that manages information about a tool for inserting / removing a plug and the adapter and the plug and presents it to an insertion / removal operator and an administrator. The present invention relates to a system and a management method.

  A connector connection board in which connector adapters are unitized uses connector plugs integrated with each adapter. Therefore, an operator who inserts / removes a connector plug through this connection panel finds the specified plug from a number of plugs or adapters, and repeats the confirmation work from the viewpoint of preventing human error, and then removes the specified plug from the adapter. Or, insert the specified plug into the specified adapter.

  In recent years, the density of plugs has been increased for the purpose of space saving, and the erroneous insertion and removal of plugs has increased. Therefore, there is a method in which a light emitting element such as an LED is arranged in the vicinity of the connector adapter, and the light emitting element arranged at the adapter position where the plug is removed is turned on to guide the adapter performing the removal work to the operator. It has been proposed (see Patent Document 1).

  However, with the insertion / extraction guidance method by lighting the light emitting element in the connector connection board as described above, although it is possible to visually guide the connector adapter to be connected / disconnected, the operator can directly obtain information on the adapter to be worked on. Therefore, there is a risk of misrecognition (human error) of the work target, which may cause erroneous connection or erroneous removal. In addition, although the connector adapter has a function of recognizing a connection target, the method does not include an identification method for the connector plug.

  On the other hand, in the current connector connection board, the introduction of QR codes is progressing for the purpose of connector plug connection. However, since the QR reader has a hardware decoding function, it is expensive and there is a demand for a reduction in price.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a conceptual diagram showing a configuration of a connector connecting apparatus to which a connector insertion / extraction tool, a connector insertion / extraction management system, and a management method according to the present invention are applied. In FIG. 1, reference numerals 111 to 113 denote existing connector connection boards in which n stations (5 stations in the figure) MU (Miniature Unit) connector adapter 12 are integrally formed. Each of the connector connection boards 111 to 113 is mounted on circuit boards 131 to 133 by printed wiring arranged in m rows (3 rows in the figure). On the circuit boards 131 to 133, the light display elements 14 such as LEDs are arranged in the plug insertion direction so as to be positioned in the vicinity of the respective connector adapters 12 of the connector wiring boards 111 to 113 mounted thereon. Placed.

  The circuit boards 131 to 133 are mounted and wired in parallel to the mother board 15, respectively. The motherboard 15 includes an information storage unit 16 for storing connector connection information of all the connector adapters 12, and displays the display of each optical display element 14 by an operator's operation input or a general-purpose PC (Personal Computer) management computer device ( Hereinafter, it is connected to a display control device (hereinafter referred to as “PCBOX”) 17 that is controlled in accordance with a designated input from the management PC) 21. The PCBOX 17 is connected to the management PC 21 through a USB (Universal Serial Bus) cable (may be a LAN cable or the like), and centrally manages information related to connection of all connector adapters of a large number of connector connection devices through the management PC 21. It is connected to the database server 22 and can acquire the identification information of the connector adapter in any connector connection device.

  The PCBX 17 constitutes a connector insertion / removal management function together with the information storage unit 16. FIG. 2 shows a specific configuration of the connector insertion / extraction management function. In FIG. 2, the PCB BOX 17 is connected to the management PC 21 via USB to input / output information, an operation input unit 172 that accepts operator's instruction operation input, and each light corresponding to all the connector adapters 12. A display processing unit 173 that controls display of the display element 14 and a display unit 174 that displays information necessary for processing of the display processing unit 173 are provided. The display processing unit 173 takes out identification information corresponding to each connector adapter 12 from the information storage unit 16 in accordance with an instruction input from the management PC 21 through the interface unit 171 or an instruction by an operation input from the operation input unit 172. The display information of the optical display element 14 is controlled.

  Writing or changing information in the information storage unit 16 is performed according to an operation input instruction from the operation input unit 172 using the display processing unit 173 and the display unit 174. In addition, an instruction from the management PC 21 may be received through the interface unit 171. The information storage unit 16 stores information such as connection information with the connector plugs of the connector adapters 12 of the connector connection boards 111 to 113, connection destination devices, service provision destination lists, wiring work histories, workers, and the like. It is held as necessary, and arbitrary information can be acquired even if the management PC 21 and the database server 22 are not connected. It is assumed that the retained data can be retained as sound or an image in addition to text data.

  As shown in FIG. 3, the circuit boards 131 to 133 include display information discriminating units A1 to An and modulation driving units B1 to Bn for each of the optical display elements 141 to 14n, and give identification information to be displayed from the PCB 17. If this is the case, it is determined whether or not the managed optical display element is the target, and in the target system, the modulation driving units B1 to Bn modulate and drive the optical display elements 141 to 14n according to the input display information, thereby identifying them. Information is transmitted on signal light. In general, intensity modulation or frequency modulation can be used as a modulation method. By providing a mode for modulating with visible light and a mode for modulating with invisible light, an operator visually confirms a specific terminal. It becomes possible.

  The operation of the connector connection system having the above configuration will be described below.

  As shown in FIG. 1, the optical display element 14 is installed in the vicinity of the terminal of the connector adapter 12 of the connector connection boards 111 to 113, and the display state of the optical display element 14 is controlled by the PCB 17. The optical display element 12 is attached to the vicinity of the connector adapter 12 on the connector connection board side of the circuit boards 131 to 133. In the connector connection boards 111 to 113 configured by n-series MU connector adapters, the display elements 3 are arranged on the circuit boards 131 to 133 according to the terminal positions of the connector adapter 12. The number of wirings can be minimized by connecting the PCB 17 and the optical display element 14 by a matrix circuit. Further, by attaching the optical display element 14 to the circuit boards 131 to 133, it can be easily attached to an existing connector connection board. By using a matrix circuit for the wiring between the PCBX 17 and the optical display element 14, the number of wirings for the plurality of optical display elements 14 can be reduced.

  When a connector plug (not shown) is connected to the designated connector adapter 12, the connection terminal can be clearly indicated by emitting the designated terminal with visible display light. The terminal display light corresponding to the connector adapter 12 can be blinked in addition to being turned on and off, and can be given meaning. When circuit boards having the optical display elements 14 mounted on both sides of the connector adapter 12 are disposed, the optical display elements 14 on both sides of the connector terminals are caused to emit light, thereby clearly indicating the positions of the connector terminals. be able to. Thus, the operator only needs to connect the connector plug to the terminal located in the vicinity of the light display element 14 that emits light, and the operation of searching for the terminal can be simplified.

  By changing the display color of the display light of the optical display element 14, it is possible to clearly indicate the type of service provided. The light display element 14 can use an LED. Small-sized LEDs are also widespread, and can be sufficiently installed even with high-density MU connector connection boards.

  In the present embodiment, the information storage unit 16 is mounted on the mother board 15 to which the connector connection boards 111 to 113 are connected. Thereby, the information storage unit 16 can hold information regarding each terminal of the connector adapter 12. Also, connection information with a connector plug or the like can be held. The information storage unit 16 can hold information such as a connection destination device, a list of service provision destinations, a history of wiring work, and workers. In addition to text data, the stored data can be stored as sound or images.

  Information is written to or changed from the information storage unit 16 using the information processing unit 173 and the display unit 174 of the PCB 17. Further, the interface unit 171 is connected to a management PC 21 using a general-purpose PC (Personal Computer), and identification information can be input / output with the PC 21.

  In the connector connection system of the above embodiment, the present invention has (1) a connector plug identification function and (2) the same erroneous connection / extraction function with respect to the connector adapter guide method using the optical display element. By using an insertion / extraction tool and (3) a connector insertion / extraction management system that uses the previous two techniques, human error of the operator is prevented, and simplification of work and reduction of work time are realized.

  The (1) connector plug identification function described above is realized by adding a QR code to each plug and using a QR reader that enables reverse encoding (decoding) of the code. Here, by using a software decode reader as the QR reader, it is possible to realize flexible cooperation with a PC application at a lower price than the existing hardware decode.

  The above-described (2) function of preventing incorrect connection / disconnection of the connector plug is realized by a light detection unit and a solenoid by a light receiving element (PD) provided in the insertion / extraction tool. That is, the operator irradiates position information from the light emitting element provided in the connector adapter with modulated light immediately before insertion / extraction, and the solenoid directly connected to the connector gripping lever only when the information is correct by the PD provided at the tip of the insertion / extraction tool. A function to prevent erroneous connection / removal of connector plugs including human error is realized by passing current and releasing the grip lock.

  The connector insertion / extraction management system that uses the above-described (3) connector plug identification method and connector plug erroneous connection / erroneous removal prevention function performs overall control by an application installed in the management PC 21.

  In FIG. 1, a feature of the connector insertion / extraction management system according to the present invention is that a management PC 21 equipped with a management system application is used, and an optical display element (light emitting element) 14 is connected to the management PC 21 with a connector adapter 12. The circuit boards 131 to 133 according to the arrangement of the above, the mother board 15 that integrates and controls a plurality of the boards, and the PCB 17 that integrates and controls the motherboard 15 are connected via a bus interface such as a USB. Further, the insertion / removal tool 23 and the QR reader 24 are connected to the management PC 21 so as to have a connector plug identification function and a connector plug erroneous connection / removal prevention function. At this time, the insertion / extraction tool 23 and the QR reader 24 may be connected to the management PC 21 or may be connected directly to the PCB 17. The working mode will be described below.

  When connecting / disconnecting, the worker carries the management system application and the management PC 21 that incorporates the subscription information database or can be externally linked using a LAN or the like, and visits the workplace. Next, the insertion / extraction tool 23 with PD and the QR reader 24 are connected to the PC 21 or the PCBOX 17, and the connection between the PCB 17 provided on the connection board and the PC 21 is performed. After confirming that they are completely connected, the worker inputs work information for connection / disconnection to the application. From this input information, the database server 22 quotes the connector plug, adapter number, and if necessary, detailed subscriber information from the subscriber information database.

  FIG. 4 shows a specific configuration when the QR reader is integrated in the connector insertion tool 23 with PD, and FIG. 5 shows a specific configuration when the QR reader is detachable. 4 and 5, (a) shows the overall configuration, and (b) shows the structure of the tip.

  The insertion / extraction tool 23 shown in FIGS. 4 and 5 manages the extending portion 231 provided with a gripping mechanism for gripping the connector plug 25 at the distal end portion, and the gripping mechanism disposed at the distal end portion of the extending portion 231. A gripping control unit 232 that performs drive control under management by the PC 21 is provided.

  The grip control unit 232 includes switches SW1 to SW4 that perform physical and electrical control of work. SW1 is a QR code reading switch, SW2 and SW3 are Y / N control switches for sending Yes / No instructions to the management PC 21, and SW4 is an ON / OFF detection switch for detecting on / off of the connection command lever 233. is there. On the other hand, a switch SW5 for detecting whether or not the connector plug 25 is gripped is provided at the distal end of the extending portion 231 so that the insertion / extraction tool 23 can be enhanced in function. In addition, a solenoid 234 that restricts the movement of the lever is mounted on the grip control unit 232, and the lever drive is turned ON / OFF by control from the application. That is, unless there is authentication from the application, the human error is prevented by not pulling the lever 233 of the insertion / extraction tool physically.

  The QR reader-integrated insertion / extraction tool 23 shown in FIG. 4 further displays a camera function unit 235 for reading a QR code, a QR code reading result, instruction / control information from the PC 21 and the like on the grip control unit 232. A display unit 236 is provided. The QR reader separation type insertion / extraction tool 23 shown in FIG. 5 has a structure in which the QR reader 24 is detachable and is automatically connected to the tool 23 side when the QR reader 24 is attached. In FIG. 5, a QR reader 24 is an interface unit (not shown) that enables transmission and reception of information when attached to the insertion / extraction tool 23, a switch SW1 for instructing QR code reading, and photographing of the QR code. And a display unit 243 for displaying a QR code reading result, insertion / extraction instruction information, and the like.

  When performing work using the above-mentioned tool, the operator can accurately recognize the adapter to be connected / disconnected by turning on the optical display element 14 close to the adapter. Next, after confirming the work plug using the QR reader 24 or its function, the insertion / extraction tool 23 is arranged at a position where the optical display element 14 can receive light. At this time, the database information and the work information are matched, and only when they match, the solenoid 234 in the insertion / extraction tool 23 is energized, and the lock on the lever 233 of the insertion / extraction tool 23 is released. As a result, the connector plug 25 can be removed, and erroneous removal and insertion / removal can be prevented when an operator mistakenly places the insertion / extraction tool 23 in a plug / adapter at a location different from the lighting position of the light display element 14. it can.

  Although this work has been described for the case where the database server 22 in which the subscription information is registered is used, when inputting the information of the connector plug / adapter to perform the work, accurate connection / removal work can be performed without using the database. Is possible.

  Here, a plurality of forms of the insertion / extraction tool are conceivable. For example, in FIG. 1, a total of three USBs are used, but space saving (reduction of the number of USBs used, tool integration) and human error that occurs when reading a flag (plug loss when changing QR reader and insertion / extraction tool) From the viewpoint of prevention and cost reduction, it is conceivable to integrate the QR reader and the insertion / extraction tool as shown in FIG.

  On the other hand, if the insertion / extraction tool 23 and the QR reader 24 are made detachable as shown in FIG. 5, the human error (the plug is lost when the insertion / extraction tool 23 and the QR reader 24 are changed) according to the business form. ) Can be combined to use the tool 23, or the QR reader 24 can be separated from the tool 22 and used for the purpose of improving handling and portability. Furthermore, as an advantage of using the separation mechanism, it is possible to replace at low cost when either the insertion / extraction tool 23 or the QR reader 24 breaks down. As will be described later, even when a separation mechanism is provided, the functions of light reception by the light detection unit PD, various controls by the switches SW1 to SW5, and prevention of erroneous removal by the solenoid are not impaired.

  FIG. 6 is a block diagram showing a circuit configuration when a QR reader is incorporated in the connector insertion / extraction tool 23 and connected to the management PC 21. The tool 23 includes a USB interface unit 23a for USB connection to the management PC 21. And the I / O control unit 23b for inputting / outputting instruction / control information to / from the PC 21 through the USB interface unit 23a, and unlocking the lever 233 (not shown) according to the instruction from the I / O control unit 23b. Solenoid 234 for displaying, a first display unit 236 for displaying its instruction / control information, a camera function unit 235 for reading the QR code, and a second display unit 237 for displaying the content of the read QR code (first display) In response to the operation input of the switches SW1 to SW5, and based on the respective instructions, Read, and a control unit 238 for controlling the connector plug grip like.

  On the other hand, the PC 21 side includes a USB interface unit 211, an image processing decoding unit 212, a serial data output unit 213, and an application unit 214. When the QR code is photographed by the camera function unit 235 of the QR reader part on the tool 23 side. The image is taken in via USB, image processing is performed by the image processing / decoding unit 212, serial data is output to the application unit 214 by the serial data output unit 213, and work plug information is extracted by the QR code conversion processing program. Send it back to the tool 23 side. As a result, it is possible to handle the heavy work of QR code image processing by the PC 21 and reduce signal processing on the tool 23 side.

  That is, overall function control is performed by the application unit 214 on the PC 21 side through a bus interface such as USB. The application unit 214 also cooperates with the database server 22 in which the subscription information is registered. Specifically, the acquired image of the QR reader is software decoded by the image processing / decoding unit 212 in the PC 21, and the information is used by the application unit 214. Also, just before insertion / extraction, the light detection unit (PD) 230 disposed at the tip of the tool 23 makes a correct / incorrect determination on each light emitting element using this application, and when it is correct, the solenoid 234 is turned on to turn on the lever 233. unlock. This function is processed regardless of whether the tool and QR reader are integrated or separated.

  FIG. 7 is a block diagram showing a circuit configuration when the connector insertion / extraction tool 23 and the QR reader 24 are separately provided and detachable. In FIG. 7, the connector insertion / extraction tool 23 side moves the I / O control unit 23 b that executes signal processing in accordance with the instruction / control information from the PC 21, the instructions by the operation inputs of the switches SW 2 to SW 5, and the movement of the lever 233 (not shown). A solenoid 234 to be regulated and a first display unit 236 for displaying instruction / control information and the like in the I / O control unit 23b are provided. Further, the QR reader 24 side is connected to the tool 23 by USB (may be directly connected to the PC 21 by USB), a USB interface unit 241, a camera function unit 242 for reading a QR code, and a QR code reading result. And a control unit 244 that performs a QR code reading process in response to an operation input of the switch SW1. By doing in this way, the connector insertion tool 23 and QR reader 24 can be easily combined and separated.

  The configuration on the PC 21 side in this case is the same as that in FIG. 6, and the QR code reading process of the QR reader 24 is processed on the PC 21 side, whereby the process of the QR reader 24 can be reduced and the cost can be reduced. be able to.

  The procedure of adapter connection / removal work using the connector insertion / extraction tool 23 and the QR reader 24 (same when integrated) will be described with reference to the flowchart shown in FIG.

  First, when work information is input by an operator (step S1), a connector plug and an adapter number corresponding to the input work information are searched from the subscription information database (step S2), and a connector connection / extraction instruction is input for the search result. Wait (step S3). If there is an input instruction, the connector selection screen is displayed (step S4), the operator's selection result is input (step S5), and the designation of the connector and adapter number is determined (step S6). If specified, the light emitting element (optical display element) corresponding to the specified adapter terminal on the connector connection board is caused to emit light with a predetermined modulation (step S7).

  Subsequently, the QR code of the plug to be connected is read by the QR reader 24 (step S8), and it is determined whether the QR code is for the designated plug (step S9). It is determined whether the predetermined modulated light emitted is received by the light detection unit 230 disposed at the tip of the insertion / extraction tool 23 (step S10). If the light is received, the lever 233 of the insertion / extraction tool 23 is unlocked. (Step S11), the connector connecting / disconnecting operation can be executed (Step S12).

  That is, according to the above processing procedure, the operator can accurately recognize the adapter to be connected / disconnected by turning on the optical display element 14 in the vicinity of the adapter during the work. Next, after confirming the work plug using the QR reader 24, the insertion / extraction tool 23 is arranged at a position where the optical display element 14 can receive light. At this time, the database information and the work information are matched, and only when they match, the solenoid 234 in the insertion / extraction tool 23 is energized and the lock on the lever 233 of the insertion / extraction tool 23 is released. As a result, the connector plug 25 can be removed, and erroneous removal and insertion / removal can be prevented when an operator mistakenly places the insertion / extraction tool 23 in a plug / adapter at a location different from the lighting position of the light display element 14. it can.

  In the flowchart shown in FIG. 8, the connector connection / disconnection instruction input determination in step S3 and the QR code reading process in steps S8 and S9 are optional and may be omitted.

  By using the connector insertion / extraction tool and the connector insertion / extraction management system with the above-described configuration and processing, the connector plug insertion / extraction operator can be surely recognized the connector plug and the adapter to be operated, thereby It is possible to prevent human error and reduce working time and work.
