[0004] However, because IC tags and reader / writers used in conjunction with IC tags communicate via radio waves, proper communication may not be possible if there is an obstacle between the IC tag and the reader / writer. This is particularly true when the obstacle is metal. For this reason, electrical and electronic equipment storage boxes made of metal have not been equipped with both IC tags and reader / writers. In addition, because many devices are installed inside an electrical and electronic equipment storage box, there are significant limitations on the installation range and orientation of IC tags and reader / writers. This has led to the belief that communication between IC tags and reader / writers inside an electrical and electronic equipment storage box is impractical. This is also one of the reasons why specific consideration has not been given to equipping an IC tag and a reader / writer inside an electrical and electronic equipment storage box. Summary of the Invention [Problem to be solved by the invention]

[0005] While pursuing various possibilities for electrical and electronic equipment storage boxes, the inventors of this invention wondered if there was a way to use IC tags and reader / writers to detect events in electrical and electronic equipment storage boxes made of metal.

DETAILED DESCRIPTION OF THE INVENTION

[0017] 1 to 4, an electrical / electronic device storage box 1 according to this embodiment includes a housing 2 capable of storing electrical / electronic devices and having at least a portion made of metal, and an outer door 3 capable of covering the housing 2. Also included within the housing 2 are an IC tag 11 that stores information about an event occurring in an object detected or measured by a sensor, a reader / writer 12 that communicates with the IC tag 11 via radio waves and collects the information, and a radio wave attenuator disposed between the IC tag 11 and the reader / writer 12 and that includes a material that attenuates, reflects, or absorbs radio waves. This allows a new means to be employed for detecting events in the electrical / electronic device storage box 1.

[0018] The IC tag 11 used in this embodiment is a so-called UHF tag, which can use radio waves in the frequency band from 300 MHz to 3 GHz. This UHF tag is capable of communication up to several meters, so the IC tag 11 has a sufficient communication distance for communication within the electrical and electronic equipment storage box 1.

[0019] In this embodiment, a radio wave attenuator having a material that performs one or more of blocking, reflecting, and absorbing radio waves is located between the IC tag 11 and the reader / writer 12. This radio wave attenuator performs one or more of blocking, reflecting, and absorbing radio waves directly between the IC tag 11 and the reader / writer 12. Typical examples of radio wave attenuators include metals that reflect or absorb radio waves, concrete that attenuates radio waves, high-density materials such as earthen walls and heat insulation materials, and wood. However, radio wave attenuators are not limited to these.

[0020] It is preferable that at least one of the radio wave attenuators is any one of an electrical / electronic device, a conductive member electrically connected to the electrical / electronic device, a fixing member used to fix the electrical / electronic device, and an inner door 4 arranged to face at least a part of the electrical / electronic device.

[0021] The presence of radio wave attenuating objects limits radio wave communication (direct communication) using the shortest path between the IC tag 11 and the reader / writer 12, but experiments by the inventor have revealed that radio waves can still communicate between the IC tag 11 and the reader / writer 12 by reflecting off walls, floors, objects, etc. (See FIG. 5.) Note that FIG. 5 shows examples of radio waves traveling from the reader / writer 12 to the IC tag 11 via the shortest distance, and radio waves traveling from the reader / writer 12 to the IC tag 11 using reflection, but when radio waves travel from the IC tag 11 to the reader / writer 12, they can also travel a similar path in the opposite direction.

[0022] Examples of radio wave reflecting members that reflect radio waves include metal walls that constitute the housing 2, the outer door 3, the inner door 4, conductive members such as electric wires and copper bars 61, conductive parts of electrical and electronic devices (terminals and contacts of electrical and electronic devices, etc.), fixing members that fix electrical and electronic devices (rail members 51, base members 52, bolts, nuts, etc.), and metal members that are installed on the housing 2, doors, or inside the housing 2, such as the inner door support member 53. Note that by providing the metal members with a bent shape or with holes, diffused reflection of radio waves is facilitated, which may facilitate communication with IC tags 11 that are in blind spots.

[0023] The IC tag 11 may be a passive tag that uses radio waves from the reader / writer 12 as an energy source, or an active tag or semi-passive tag that has a built-in battery, but the former is preferred from the standpoint of cost and battery maintenance.

[0024] Furthermore, the reader / writer 12 can read the IC tag 11 by transmitting data in response to a signal received from the reader / writer 12. In this case, it is possible to read information from multiple tags. Alternatively, it is possible to transmit data when the IC tag 11 receives a transmission command from the reader / writer 12. In this case, it is possible to control the communication of the IC tag 11.

[0025] The IC tag 11 may be a sticker-type tag, a tag made of ceramic material, or a tag for a specific purpose, but it is preferable that it is a metal-compatible tag that is less susceptible to the influence of metal, such as a metal-compatible tag that can be read even when attached to a metal surface.

[0026] The radio waves emitted from the reader / writer 12 (strictly speaking, from an antenna provided in the reader / writer 12 or an antenna connected to the reader / writer 12) can be linearly polarized or circularly polarized, and the ease of reading information varies depending on the installation direction of the IC tag 11. Since circularly polarized waves are compatible with reading IC tags 11 in a wider variety of orientations, it is preferable that the radio waves emitted from the reader / writer 12 be circularly polarized.

[0027] Incidentally, the radio waves emitted from the reader / writer 12 include radio waves that reach the IC tag 11 directly and radio waves that reach the IC tag 11 after being reflected by surrounding objects, and therefore a phenomenon may occur in which the radio waves strengthen or weaken each other.

[0028] The electrical and electronic equipment storage box 1 of the embodiment includes a housing 2 made of a metal plate, and metal plate-like portions exist above, below, to the right, left, and rear as viewed from the center of the housing 2. The outer door 3, which is located in front of the housing 2 when closed, is also made of a metal plate, and a metal plate-like portion exists in front as viewed from the center of the housing 2. In other words, in the embodiment, when the outer door 3 is closed, metal plate-like portions exist on all four sides as viewed from the center of the housing 2, and this configuration makes it easy for radio waves generated within the housing 2 to be reflected.

[0029] The IC tag 11 of the embodiment is integrated with a sensor and stores information detected or measured by the sensor about events occurring in the object, as well as ID information. However, the IC tag 11 and the sensor may not be integrated. In this case, it is preferable that information sent from the sensor to the IC tag 11 be stored in the IC tag 11. It is also preferable that the information stored in the IC tag 11 be updated by sending information from the sensor to the IC tag 11.

[0030] If the sensor and IC tag 11 are integrated, it is expected that the space required for their placement can be reduced and the wiring can be simplified. On the other hand, if the sensor and IC tag 11 are separate, it becomes possible to replace the sensor without changing the IC tag 11.

[0031] Examples of sensors include sensors that monitor the state of electricity flowing through electrical and electronic devices (current sensors, voltage sensors, power sensors, discharge accident detection sensors, insulation degradation detection sensors, etc.). Other examples include sensors that monitor the vibration, strength, failure, and damage of electrical and electronic devices (acceleration sensors, pressure sensors, sound sensors, etc.). Other examples include sensors that monitor abnormal temperatures and fires in electrical and electronic devices (temperature sensors, flame sensors, smoke sensors, light sensors, odor sensors, dust sensors, etc.). Other examples include sensors that monitor the effects of natural disasters on electrical and electronic devices (acceleration sensors, lightning sensors, flood sensors, water level sensors, humidity sensors, etc.). Other examples include sensors that monitor the environmental conditions inside electrical and electronic device storage boxes (humidity sensors, air pressure sensors, illuminance sensors, etc.). However, any sensor that measures or detects events related to electrical and electronic devices may be used. Furthermore, the grouping of sensors is not limited to the above examples.

[0032] Hereinafter, when describing the placement of the IC tag 11, unless otherwise specified, the description will be made assuming that the sensor and the IC tag 11 are one unit. When assuming that the sensor and the IC tag 11 are separate, the placement of the "IC tag 11" can be considered to be a description of the placement of at least one of the "IC tag 11" and the "sensor."

[0033] The IC tag 11 may be attached to any of the housing 2, the door, or the rail member 51 stored within the housing 2, but it is preferable to attach it to a location where it can obtain the information necessary to detect abnormalities in the electrical and electronic equipment or the electrical and electronic equipment storage box 1 based on an event occurring in the object.

[0034] For example, if the information stored in the IC tag 11 is temperature, a conductive part or interior of an electrical or electronic device that is prone to temperature rise, or a conductive member such as an electric wire or copper bar 61, is a preferred attachment position for the IC tag 11. If the information stored in the IC tag 11 is information about insulation deterioration detection, an electric wire or copper bar 61 is a preferred attachment position for the IC tag 11. If the information stored in the IC tag 11 is information about flames or smoke, the upper part of the housing 2 is a preferred attachment position for the IC tag 11. If the information stored in the IC tag 11 is information about flooding or water levels, the lower part of the housing 2 is a preferred attachment position for the IC tag 11.

[0035] It is also preferable to attach the IC tag 11 to the outer surface (the front, side, bottom surface, etc. of the breaker 62) or inner surface (walls around the contact points of the electrical electronic device), the surface of a conductive member such as an electric wire or copper bar 61, the conductive part of the electrical electronic device (terminal part of the electrical electronic device, contact points inside the electrical electronic device, etc.), fixing members used to fix the electrical electronic device (base member 52, rail member 51, etc.), wall surfaces (left and right side surfaces, top surface, bottom surface) that make up the housing 2, the middle door 4, the outer door 3, etc.

[0036] It is preferable that the IC tag 11 is attached to at least one of the housing 2, the outer surface of the electrical and electronic device stored in the housing 2, the inner surface of the electrical and electronic device stored in the housing 2, and a fixing member used to fix the electrical and electronic device.

[0037] In particular, when multiple electrical and electronic devices are placed adjacent to each other, it is preferable to attach IC tags 11 between the electrical and electronic devices (see FIG. 6). This is because such areas tend to trap heat, and therefore infrared sensors cannot detect the information to be detected, even though it contains the information to be detected.

[0038] Furthermore, when copper bars 61 are stacked, heat tends to accumulate more easily in the other copper bars 61 than in the topmost copper bar 61. For this reason, it is possible to attach IC tags 11 to all of the stacked copper bars 61 (see FIG. 7), or to attach IC tags 11 only to copper bars 61 that tend to accumulate heat. In the former case, it becomes possible to compare the copper bars 61 with the other copper bars 61, and in the latter case, it becomes possible to reduce the number of IC tags 11.

[0039] If the IC tag 11 is attached to the copper bar 61 located on the back side of the middle door 4, it will be possible to obtain information using a sensor without opening the middle door 4. On the other hand, if infrared rays or the like are used to measure the temperature of the copper bar 61, it is difficult to measure in a hidden location, and even if measurement is to be performed in a location where measurement is possible, a qualified person will have to open the middle door 4 to do the work; however, if the IC tag 11 is used, such problems can be avoided.

[0040] As can be understood from these descriptions, it is preferable that the IC tag 11 is attached to a conductive member or a conductive part of an electric or electronic device.

[0041] It is also possible to install the IC tag 11 on the inner door 4 or outer door 3. For example, when the IC tag 11 is placed on one side of the inner door 4 and the reader / writer 12 is placed on the other side, communication between the IC tag 11 and the reader / writer 12 can be performed simply by leaving a small gap between the housing 2 and the inner door 4. This is because radio waves can travel while being reflected by the housing 2, inner door 4, outer door 3, etc. (see FIG. 8).

[0042] Because this is possible, it is preferable to further provide an inner door 4 that can cover the conductive parts of multiple electrical and electronic devices stored in the housing 2 and allows access to a portion of the non-conductive part of at least one of the electrical and electronic devices, and to have at least one of the IC tags 11 attached to either the surface of the outer door 3 facing the inner door 4, the surface of the inner door 4 facing the outer door 3, or between the inner door 4 and the outer door 3.

[0043] Here, the reader / writer 12 will be described in more detail. The reader / writer 12 communicates with the IC tag 11 via radio waves, and one of its functions is to acquire information stored in the IC tag 11, but this is not a limitation. For example, if the IC tag 11 is a passive tag, the reader / writer 12 transmits a signal to the IC tag 11 indicating that information is to be transmitted. When the IC tag 11 receives the corresponding radio waves, it operates using the radio waves as its energy source. This is because passive tags do not have an energy source such as a battery. In this way, the radio waves transmitted from the reader / writer 12 can also be used as an energy source for the IC tag 11.

[0044] If the IC tag 11 is a semi-passive tag (semi-active tag), the IC tag is equipped with a battery, but the radio waves sent from the reader / writer 12 are used as a cue for the need for a response from the IC tag 11. In either case, the IC tag 11 transmits the stored information to the reader / writer 12, which receives it, allowing the information to be collected by the reader / writer 12.

[0045] The reader / writer 12 of the embodiment is capable of external communication to output information to a device other than the reader / writer 12. The reader / writer 12 of the embodiment also includes a determination unit that makes a determination based on the collected information. However, the determination unit does not have to be included in the reader / writer 12, and the determination unit may be included in a device or the like that acquires information as a result of the reader / writer 12 performing external communication.

[0046] The reader / writer 12 of the embodiment can transmit alarm information via external communication based on the determination result of the determination unit. Also, to enable on-site confirmation of an abnormality, a light, a screen, or a movable part provided in the reader / writer 12 may be operated to recognize the abnormality.

[0047] Incidentally, the reader / writer 12 of the embodiment can transmit a signal to transmit information to a plurality of IC tags 11, and can receive information from a plurality of IC tags 11. In this case, if ID information is added to the information from the IC tags 11, it becomes possible to identify the source of each piece of information.

[0048] One of the functions of the reader / writer 12 is to write information to the IC tag 11. For example, the reader / writer 12 transmits a signal to the IC tag 11 indicating that the settings are to be changed. When the IC tag 11 receives the corresponding radio waves, it starts up using the radio waves as its energy source. The IC tag 11 then waits in a setting change mode. After that, when the reader / writer 12 transmits a signal related to the "change information" again, the settings of the IC tag 11 are changed.

[0049] However, considering the directionality of the IC tag 11 and the reader / writer 12, if the IC tag 11 is not located in the direction of the radio waves emitted by the reader / writer 12, or if the reader / writer 12 is not located in the direction of the radio waves emitted by the IC tag 11, it was thought that it would be difficult to communicate between the IC tag 11 and the reader / writer 12 even if there was no radio wave attenuating material between them.

[0050] However, when an experiment was conducted by placing an IC tag 11 and a reader / writer 12 inside the electrical and electronic equipment storage box 1, it was found that communication was possible even with such an arrangement. This is thought to be because radio waves were reflected inside the electrical and electronic equipment storage box 1, and were sent in a direction that allowed them to be received (see Figure 9).

[0051] In other words, it was found that the radio waves sent from the IC tag 11 and the reader / writer 12 can have their direction changed by the presence of a radio wave reflecting material in their path, and therefore the problem of restrictions on the orientation and placement of the IC tag 11 and the reader / writer 12 can be largely resolved.

[0052] For example, if "IC tag 11 is installed in an area where the intensity of radio waves directly emitted from reader / writer 12 is weak, and a radio wave reflecting member is located in an area where the intensity of radio waves directly emitted from reader / writer 12 is strong," or "reader / writer 12 is installed in an area where the intensity of radio waves directly emitted from IC tag 11 is weak, and a radio wave reflecting member is located in an area where the intensity of radio waves directly emitted from IC tag 11 is strong," radio waves transmitted from reader / writer 12 or IC tag 11 can be reflected by the radio wave reflecting member in an area where the intensity of directly emitted radio waves is strong, in other words, an area where stable reading is possible, and communication can be performed even if the receiving target is located in an area where the intensity of directly emitted radio waves is weak, in other words, an area where stable reading is difficult. Note that "direct irradiation" here means irradiation by radio waves that are not reflected.

[0053] For this reason, it is preferable to have an electrical and electronic equipment storage box 1 that is capable of storing electrical and electronic equipment and that comprises a housing 2 that has at least a portion made of metal, and an outer door 3 that can cover the housing 2, and that comprises, within the housing 2, an IC tag 11 that stores information detected or measured by a sensor about an event occurring in the object, and a reader / writer 12 that communicates with the IC tag 11 via radio waves and collects the information, with the IC tag 11 installed in an area where the strength of the radio waves directly irradiated from the reader / writer 12 is weak and a radio wave reflecting member located in an area where the strength of the radio waves directly irradiated from the reader / writer 12 is strong, or the reader / writer 12 is installed in an area where the strength of the radio waves directly irradiated from the IC tag 11 is weak and the radio wave reflecting member located in an area where the strength of the radio waves directly irradiated from the IC tag 11 is strong.

[0054] Furthermore, if "the IC tag 11 is installed outside the area directly irradiated by the reader / writer 12 and a radio wave reflecting member is located within the area," or "the reader / writer 12 is installed outside the area directly irradiated by the IC tag 11 and a radio wave reflecting member is located within the area directly irradiated by the IC tag 11," the radio waves transmitted from the reader / writer 12 or the IC tag 11 can be reflected by the radio wave reflecting member, thereby enabling communication even if a receiving target exists outside the area directly irradiated by the radio wave. Note that the "area directly irradiated by the radio wave" here refers to an area irradiated by unreflected radio waves. Also, "outside the area directly irradiated by the radio wave" here is an example of an area where the strength of the directly irradiated radio waves is weak, and "inside the area directly irradiated by the radio wave" is an example of an area where the strength of the directly irradiated radio waves is strong.

[0055] For this reason, it is preferable to have an electrical and electronic device storage box 1 that is capable of storing electrical and electronic devices and that comprises a housing 2 that has at least a portion made of metal, and an outer door 3 that can cover the housing 2, and that comprises, within the housing 2, an IC tag 11 that stores information detected or measured by a sensor about an event occurring in the object, and a reader / writer 12 that communicates with the IC tag 11 via radio waves and collects the information, and that the IC tag 11 is installed outside the direct radio wave irradiation area of ​​the reader / writer 12 and a radio wave reflecting member is positioned within the radio wave irradiation area, or that the reader / writer 12 is installed outside the direct radio wave irradiation area of ​​the IC tag 11 and a radio wave reflecting member is positioned within the radio wave irradiation area.

[0056] Furthermore, if "IC tag 11 is positioned in the direction of radio wave emission from reader / writer 12 as seen from reader / writer 12, but the radio wave receiving unit of IC tag 11 does not face reader / writer 12, and a radio wave reflecting member is positioned in the direction of radio wave emission," or "reader / writer 12 is positioned in the direction of radio wave emission from IC tag 11 as seen from IC tag 11, but the radio wave receiving unit of reader / writer 12 does not face IC tag 11, and a radio wave reflecting member is positioned in the direction of radio wave emission," the radio waves sent from reader / writer 12 or IC tag 11 can be reflected by the radio wave reflecting member, making it possible to perform communication even if the radio wave emission direction and the radio wave receiving unit are not facing each other.

[0057] For this reason, it is preferable to provide an electrical and electronic device storage box 1 that is capable of storing electrical and electronic devices and that comprises a housing 2 that has at least a portion made of metal, and an outer door 3 that can cover the housing 2, and that comprises, within the housing 2, an IC tag 11 that stores information detected or measured by a sensor about an event occurring in the object, and a reader / writer 12 that communicates with the IC tag 11 via radio waves and collects the information, wherein the IC tag 11 is located in the radio wave emission direction of the reader / writer 12 as seen from the reader / writer 12, but the radio wave receiving unit of the IC tag 11 does not face the reader / writer 12 and a radio wave reflecting member is located in the radio wave emission direction, or the reader / writer 12 is located in the radio wave emission direction of the IC tag 11 as seen from the IC tag 11, but the radio wave receiving unit of the reader / writer 12 does not face the IC tag 11 and a radio wave reflecting member is located in the radio wave emission direction.

[0058] Furthermore, if "the IC tag 11 is installed in a direction different from the radio wave irradiation direction of the reader / writer 12 as viewed from the reader / writer 12, and a radio wave reflecting member is positioned in the radio wave irradiation direction," or "the reader / writer 12 is installed in a direction different from the radio wave irradiation direction of the IC tag 11 as viewed from the IC tag 11, and a radio wave reflecting member is positioned in the radio wave irradiation direction," the radio waves transmitted from the reader / writer 12 or the IC tag 11 can be reflected by the radio wave reflecting member, thereby enabling communication even if a receiving target exists in a direction different from the radio wave irradiation direction. Note that the "radio wave irradiation direction" here refers to the direction of irradiation of radio waves that are not reflected. Also, the "direction different from the radio wave irradiation direction" here is an example of an area where the strength of directly irradiated radio waves is weak, and the "radio wave irradiation direction" is an example of an area where the strength of directly irradiated radio waves is strong.
