I have. As described above, if the holder 13 that can be connected to the plurality of environment information detecting units 12 is provided, it is not necessary to connect the monitoring module 31 and the environment information detecting unit 12 individually, and the holder 13 and the environment information If the wiring section 14 is provided by wiring in advance to the detection means 12, even if an item to be newly measured is created, the function of the electrical and electronic equipment storage box 1 is stopped for a long time for wiring work. You can avoid the situation that must be done. Therefore, it is possible to obtain monitoring information as needed. At the beginning of shipment, if the monitoring module 31 having only necessary functions is connected to the holder 13, the initial cost of the monitoring module 31 can be reduced.

  In the example shown in FIG. 1, the holder 13 is installed in the box body 11, and the environment information detecting unit 12 that transmits information to the monitoring module 31 connected to the holder 13 is inside and outside the box body 11. Has also been installed. In the example shown in FIG. 1, the monitoring module 31 calculates information obtained from the environment information detecting means 12 and sends the calculation result to the recording device 2 connected by wire. Further, a sub-module 32 used to extend the function can be connected to the monitoring module 31 shown in FIG. Note that the monitoring module 31 may access the environment information detecting means 12 to acquire information.

  Here, the holder 13 will be described. In the example shown in FIG. 2, the holder 13 is provided with a sensor connection portion 51 so as to be connectable to a plurality of environmental information detecting means 12. The sensor connection unit 51 of the embodiment includes a plurality of terminals, and wiring is performed so that the environmental information detection unit 12 is connected to all or some of the terminals. In the embodiment, the environment information detecting means 12 and the terminal portions are connected so as to correspond one-to-one, and in the case of the example shown in FIG. Wired to the terminal.

  For example, in the case of a switchboard, the sensor connection unit 51 supplies power to the monitoring module 31 via the sensor connection unit 51 if it is connected to a bus bar or the like provided inside the box body 11 by wiring. it can. In addition, for example, the wiring of the power supply unit 15 provided in any of the environment information detection units 12 may be connected to the sensor connection unit 51. In this way, power can be supplied to the monitoring module 31 from the holder 13 that is electrically connected to the power supply unit 15 in the box body 11. Therefore, it is possible to supply power to the monitoring module 31 only by connecting the monitoring module 31 to the holder 13 without separately preparing an external power supply.

  The holder 13 is provided with a monitoring module connection section 52 so that the information input to the sensor connection section 51 can be output to the monitoring module 31. The monitoring module connection part 52 is a part that can be electrically connected to the terminal connection part 33 provided in the monitoring module 31. By connecting the monitoring module connection unit 52 and the terminal connection unit 33, the sensor connection unit 51 and the monitoring module 31 are electrically connected. In the embodiment, the monitoring module connection part 52 is provided inside the holder 13, and the sensor connection part 51 is provided outside the holder 13.

  The holder 13 of the embodiment has a guide 42 so that the monitoring module 31 can be slid. When the monitoring module 31 is moved so that the terminal connection part 33 of the monitoring module 31 is in contact with the monitoring module connection part 52 of the holder 13, the guide 42 can be used, so that the terminal connection part 33 and the monitoring module can be smoothly connected. The connecting portion 52 can be brought into contact. Note that the guide 42 of the embodiment is provided in a convex shape, and a groove 41 into which the convex guide 42 can be inserted is provided in the monitoring module 31.

  As can be understood from FIG. 2, the holder 13 preferably has a guide 42 on the inner side surface. Further, when viewed in the mounting direction of the monitoring module 31, it is preferable that one of the four sides is open, and it is particularly preferable that the lower end be open. By doing so, it becomes possible to lengthen the monitoring module 31 and the like to the open side. For example, when the lower end is open, the monitoring module 31 attached to the holder 13 can be attached even if it is elongated downward. Further, the monitoring module 31 can be attached to the holder 13 even if the sub-module 32 is connected below the monitoring module 31.

  The monitoring module 31 of the embodiment can be connected to a sub-module 32 used to extend the function. This submodule 32 is connected so as to overlap with the monitoring module 31. In the example shown in FIGS. 3 and 4, the monitoring module 31 has a guide groove 34. The sub-module 32 is provided with a projecting portion 35 that can be inserted into the guide groove 34. The guide groove 34 is provided with a portion where the distance of the facing surface becomes longer toward the back side, and the projecting portion 35 is provided with a portion which becomes wider toward the distal end side so as to correspond to the guide groove 34. I have. For this reason, the projecting portion 35 can be fitted and slid in the guide groove 34, and the sub-module 32 can be easily attached or detached. The monitoring module 31 may be provided with a projecting portion 35, and the submodule 32 may be provided with a guide groove 34 corresponding to the projecting portion 35.

  As understood from the examples shown in FIGS. 3 and 4, the sub-modules 32 can be connected so that the sub-modules 32 overlap each other. The sub-module 32 has a guide groove 34. The sub-module 32 is provided with a projecting portion 35 that can be inserted into the guide groove 34. The guide groove 34 and the projecting portion 35 have the same shape as the guide groove 34 and the projecting portion 35 used in the monitoring module 31 and the submodule 32. The connection structure between the monitoring module 31 and the sub-module 32 and the connection structure between the sub-modules 32 are not limited to the present embodiment, but may be such that concave portions and convex portions are provided and engaged.

  As can be understood from FIG. 5, the monitoring module 31 of the embodiment includes a sub-module connection unit 36 that can be electrically connected to the sub-module 32 used to extend the function. Therefore, if the sub-module 32 is connected to the monitoring module 31 when necessary, the sub-module 32 corresponding to the added environment information detecting means 12 can be connected even if the environmental information detecting means 12 not corresponding to the monitoring module 31 is additionally connected. If added, the information of the environment information detecting means 12 can be transmitted and received, and the information can be transmitted and received between the monitoring module 31 and the sub-module 32. The sub-module connection section 36 has a portion used as an input portion or an output portion of a power supply and a portion used as an input portion or an output portion of information. The sub-module connection unit 36 is also provided in the sub-module 32, and can transfer power and information only when the sub-module connection units 36 are at opposing positions. Note that the sub-module connecting portion 36 may connect the connectors to each other for electrical connection.

  In the embodiment, the monitoring module 31 includes a module power supply unit 81 that supplies power to each unit, a measurement unit 82 that detects measurement information of each environment information detection unit 12, a processing unit 83 that calculates measurement information, An output unit 84 for outputting information to the outside, and a display unit 85 for displaying information output from the output unit 84 on the monitoring module 31 are provided. Further, the sub-module 32 includes a measuring unit 82 for detecting the measurement information of each environment information detecting unit 12 and a processing unit 83 for calculating the measurement information. In the embodiment, the display unit 85 is formed on the monitoring module. However, the display unit 85 can be displayed not on the monitoring module 31 but on a display device (not shown) formed outside via the output unit 84. .

  The module power supply unit 81 provided in the monitoring module 31 can supply power to the submodule 32 via the submodule connection unit 36. When connected so that information can be transmitted between the sub-module 32 and the monitoring module 31 via the sub-module connection unit 36, the result calculated by each processing unit 83 of the sub-module 32 is The data can be collected by the processing unit 83A and output to the outside by the output unit 84.

  By the way, in the example shown in FIG. 1, the holder 13 is attached to the middle door 18 of the box 1 for storing electric and electronic equipment, but as shown in FIG. 6, the opening of the box body 11 of the box 1 for storing electric and electronic equipment is closed. The holder 13 may be attached to the door 17. The holder 13 is preferably attached to a door or a protective cover that covers the power supply unit 15 in the box body 11. In this case, the holder 13 can be used only by a specific person such as the installer of the electric and electronic equipment storage box 1. Further, it may be attached to a member that covers the device, such as a meter panel. It is preferable that the holder 13 be attached to the back surface of the door 17 or the like so that the holder 13 is exposed when the door 17 or the like is opened. In this case, the monitoring module 31 is connected without touching internal devices and wiring. be able to.

  In addition, the monitoring system 10 of the electrical and electronic equipment storage box 1 may collect environmental information by adding an environmental information detecting unit 12 that is not connected to the wiring unit 14. In the example shown in FIG. 7, an environment information detecting unit 12 including an RFID (Radio Frequency Identification) tag 61 is added. Further, the sub-module 32 provided with the RFID tag 61 is connected to the monitoring module 31 in order to correspond to the environment information detecting means 12 provided with the RFID tag 61. In this way, it is possible to perform wireless communication between the environment information detecting means 12 having the RFID tag 61 and the submodule 32 having the RFID tag 61. Therefore, the labor for connecting the environment information detecting means 12 and the holder 13 in advance can be reduced.

  The wiring section 14 may be connected to a sensor holder 16 to which the environmental information detecting means 12 can be attached, in addition to the plurality of environmental information detecting means 12. In the example shown in FIG. 8, the environment information detecting means 12 is attached to the sensor holder 16 connected to the wiring section 14. Since the wiring between the sensor holder 16 and the holder 13 is made in advance, it can be easily performed later when the environmental information detecting means 12 is incorporated into the electric / electronic equipment storage box 1 later.

  In the example shown in FIG. 1 and the like, the monitoring module 31 is connected to the recording device 2 by wire, and transmits information from the monitoring module 31 to the outside. A different device may be used. For example, in the example shown in FIG. 9, information is transmitted from the environment information detecting means 12 attached to the box body 11 to the outside. For this reason, one of the environmental information detecting means 12 is capable of transmitting information bidirectionally with the monitoring module 31. Further, the information of the monitoring module 31 is communicated with the outside using the communication unit 71 provided in the environment information detecting means 12. In this way, a monitoring company or the like can obtain information even when the monitor is away from the electric / electronic device storage box 1. Further, since it is not necessary to incorporate the communication unit 71 that communicates with the recording device 2 into the monitoring module 31, the monitoring module 31 can be prevented from becoming complicated and can be downsized. In addition, it is preferable that the environmental information detecting means 12 including the communication unit 71 such as an antenna is mounted outside the box 1 for storing electric and electronic equipment.

  By the way, the monitoring module 31 may be always mounted on the holder 13 or may be mounted on the holder 13 for a specific period (such as a period during which information is input to the recording device 2). When the monitoring module 31 is always mounted on the holder 13, it is preferable to connect the monitoring module 31 mounted on the holder 13 to the recording device 2 by connecting the connector 72 to the monitoring module 31 when extracting information. (See FIG. 10). In this case, when the connector connecting portion 74 for connecting the connector 72 is exposed, the connector 72 can be connected to the monitoring module 31.

  When the monitoring module 31 is mounted on the holder 13 only during a specific period such as a period during which information is input to the recording device 2, one monitoring module 31 may be used for a plurality of electric / electronic device storage boxes 1. (See FIG. 11). In this case, since the monitoring module 31 does not need to be incorporated in each electrical and electronic equipment storage box 1, the initial cost of the electrical and electronic equipment storage box 1 can be reduced. Further, the holder 13 may be arranged in a box 100 for storing electrical and electronic equipment other than the box 1 for storing electrical and electronic equipment to be measured (see FIG. 12).

  The type of the environmental information detecting means 12 and the information sent by the environmental information detecting means 12 are not particularly limited, but include an outside air sensor for detecting temperature and humidity, a wireless antenna, an auxiliary signal of a circuit breaker, an alarm signal, Examples include the internal temperature signal of the transformer and the capacitor, the voltage, current, power, power signal of each system, the door open / close signal, the insulation deterioration signal of the box body 11, the leakage detection signal, and the like.

  As described above, the present invention has been described by taking the embodiment as an example. However, the present invention is not limited to the above embodiment, and can be various modes. For example, the box for storing electrical and electronic equipment of the present embodiment is a cubicle, but may be a switchboard or the like. Further, a breaker, a transformer, an internal device, a bus bar used for power supply, and the like can be arranged inside.
