Embodiments for Carrying Out the Invention

[0015] Embodiments for carrying out the invention are shown below. As can be understood from what is shown in FIG. 1, the present embodiment relates to a box 1 for housing electrical and electronic equipment in which electrical and electronic equipment is housed inside a housing 11.

[0016] In general, the box 1 for housing electrical and electronic equipment is composed of electrical and electronic equipment such as a circuit breaker 63, a switch, a transformer 62, a relay, a communication device, a measuring device, a control device, a sensor device, an air conditioning device, a server, etc., and a housing 11 for housing them. For example, it refers to a distribution board, a switchboard, a control panel, high-voltage power receiving equipment (including cubicle-type high-voltage power receiving equipment), a system rack, etc. However, here, the box 1 for housing electrical and electronic equipment is assumed to include a work box. In general, the work box is equipped with a communication device, lighting equipment, a desk, a chair, etc., and is for people to work inside.

[0017] Here, a monitoring device 3 installed in the box 1 for housing electrical and electronic equipment will be described. As can be understood from what is shown in Fig. 2, the monitoring device 3 installed in the box 1 for housing electrical and electronic equipment in this embodiment is installed in the box 1 for housing electrical and electronic equipment where electrical and electronic equipment is housed inside the housing 11. Also, as can be understood from what is shown in Fig. 3, this monitoring device 3 includes a monitoring unit 32 for monitoring at least any one of events occurring in an electrical and electronic device, the housing 11, the environment inside the housing 11, or the surroundings of the housing 11, and a driving unit 33 for moving inside or on the outer surface of the housing 11. Therefore, it is possible to grasp events occurring in various places near the housing 11 of the box 1 for housing electrical and electronic equipment with a small number of sensors, and it is also possible to improve the workability of the installation work and inspection work of the sensors. Note that it is preferable that the monitoring device 3 is movable on a rail 7 installed inside or on the outer surface of the housing 11 (see Figs. 4 and 5).

[0018] Also, a monitoring system for monitoring the box 1 for housing electrical and electronic equipment using the monitoring device 3 installed in the box 1 for housing electrical and electronic equipment, wherein the monitoring device 3 is controlled to move inside or on the outer surface of the housing 11 for monitoring, is preferable.

[0019] The monitoring device 3 installed in the box 1 for housing electrical and electronic equipment is installed so as to be movable inside or on the outer surface of the box 1 for housing electrical and electronic equipment. The monitoring device 3 monitors the inside and outside of the housing 11 of the box 1 for housing electrical and electronic equipment and detects abnormalities and dangers in the housing 11. For example, it may be a device that photographs the presence or absence of rust, holes, dents, etc. on the surfaces (ceiling surface, left and right side surfaces, front and rear side surfaces, bottom surface, etc.) constituting the housing 11, the door 12, columns, frames, etc. with a camera, or a device that measures or detects small animals and insects that invade the inside of the box 1 for housing electrical and electronic equipment with an infrared sensor, rainwater, flood, etc. with a water level sensor, etc. Also, it may be a device that monitors the electrical and electronic equipment housed in the housing 11 and detects abnormalities and dangers in the electrical and electronic equipment. For example, it may be a device that measures or detects temperature abnormalities and discharge events at the terminal part of the circuit breaker 63, abnormal vibrations and sounds of the transformer 62, etc. with various sensors.

[0020] The monitoring device 3 includes a monitoring unit 32 that can be used to monitor events occurring in the electrical and electronic equipment, the housing 11, the environment inside the housing 11, or the surroundings of the housing 11, and a driving unit 33 that can be used to move inside or on the outer surface of the housing 11. The monitoring device 3 of the embodiment includes a main body 31 to which they are attached, but the monitoring device 3 may be provided with other functional parts such as a power unit and a communication unit.

[0021] The monitoring unit 32 provided in the monitoring device 3 is a sensor, a camera, etc., and can monitor events occurring in the electrical and electronic equipment housed in the housing 11, the internal space of the housing 11, the members constituting the housing 11, or the surroundings of the housing 11. The sensor and the camera may be exposed outside the monitoring device 3, but if they are covered with a transparent member, the function will not be impaired and the sensor and the camera can be protected from dust and dirt.

[0022] Various types of sensors can be considered for the monitoring unit 32, for example, the following ones. Sensors for monitoring the environment inside the housing 11 (temperature sensor, humidity sensor, CO2 sensor, barometric pressure sensor, etc.), sensors for monitoring the state of the electricity flowing through the electrical and electronic equipment (current sensor, voltage sensor, power sensor, discharge accident detection sensor, insulation degradation detection sensor, etc.), sensors for monitoring the vibration, strength, failure, and damage of the housing 11 and the electrical and electronic equipment (acceleration sensor, pressure sensor, sound sensor, etc.), sensors for monitoring the fire inside the housing 11 (flame sensor, smoke sensor, light sensor, odor sensor, dust sensor, etc.), sensors for monitoring natural disasters to the housing 11 and the electrical and electronic equipment (acceleration sensor, lightning sensor, water immersion sensor, water level sensor, snow accumulation sensor, etc.), and other sensors (ultraviolet sensor, infrared sensor, etc.). Of course, not only the sensors exemplified here can constitute the monitoring unit 32, but any sensor that can measure or detect at least an event occurring in any one of the electrical and electronic equipment, the housing 11, the environment inside the housing 11, or the surroundings of the housing 11 may be used. Also, the grouping of the sensors is not limited to these.

[0023] On the other hand, the camera that constitutes the monitoring unit 32 may be any camera that captures the appearance and interior of the box 1 for storing electrical and electronic devices and the status of the electrical and electronic devices by means of still images or moving images. It may be equipped with known camera functions such as a function to change the angle of the camera, a zoom function for an object at a remote location, and an infrared imaging function that can capture images even in the dark.

[0024] It may also be configured to have a function of determining the images captured by a camera or the like. In this case, as an example, the determination based on the captured images may be to grasp abnormalities and dangers by comparing a plurality of images with different shooting times and locations. For example, changes, abnormalities, or dangers may be detected by comparing images taken at different times of the same location on the housing 11 or the same electrical and electronic device. Of course, the state of electrical and electronic devices and the like may also be determined using a plurality of types of information obtained by changing the shooting angle.

[0025] Also, the camera and the sensor may be interlocked. For example, after an abnormality or danger is detected by the sensor, the camera may capture the target location, or conversely, after an abnormality or danger is detected by the image captured by the camera, the sensor may be used to investigate the cause.

[0026] The measurement, detection, and imaging by the monitoring unit 32 may be performed at regular intervals, or may be performed by means of remote operation or the like. The data and information obtained by the measurement, detection, imaging, etc. by the monitoring unit 32 may be directly communicated by the communication unit, but may also be communicated after the data and information are determined by the monitoring unit 32 or a determination unit connected to the monitoring unit 32. At this time, it may be such that communication is performed only when an abnormality is determined as a result of the determination.

[0027] In the monitoring unit 32, measurement, detection, and imaging are performed constantly, but not all data and information are determined by the determination unit. It may be such that determination and communication are performed at regular intervals.

[0028] The determination by the determination unit may be to set a predetermined threshold value for each event and determine it as abnormal when the threshold value is exceeded or fallen below. Alternatively, it may be to compare information measured or detected at different times or locations, or photographed data or information, or compare them after calculation to determine an abnormality.

[0029] At this time, when the event to be monitored is temperature or humidity, since the influence of the temperature outside the housing 11 on the temperature measured inside the housing 11 is large, it is preferable that after performing calculations such as subtracting the temperature measured outside the housing 11 from the temperature measured inside the housing 11, it is determined by the determination unit.

[0030] The monitoring device 3 in the present invention can move inside or on the outer surface of the housing 11, and can measure, detect, or photograph data and information at different locations in the same time zone. Therefore, it is possible to achieve more accurate monitoring with one monitoring device 3. For example, in the same time zone, determination can be made using the temperature information measured at a position close to the target electrical and electronic device and the temperature information measured on the outer surface of the housing 11, or determination can be made using the temperature information measured at a position close to the electrical and electronic device and the temperature information measured at a position inside the housing 11 that is not affected by the heat from the electrical and electronic device in the same time zone, and so on.

[0031] The monitoring device 3 is provided with a drive unit 33 so that the monitoring unit 32 provided in the monitoring device 3 can be moved to various locations. For example, the drive unit 33 includes wheels having a tread portion 33ab and a gear portion 33aa, and a drive shaft such as a shaft that transmits the power generated by a power unit such as a motor to the drive wheels.

[0032] In the example here, the drive unit 33 includes a first wheel 33a1 located on the traveling side of the monitoring device 3 and a second wheel 33a2 located inside the main body 31 (see FIGS. 4 and 5). The power generated by the power unit is preferably transmitted to at least the wheels that contact the surface constituting the housing 11 or the traveling surface 76 on the rail 7.

[0033] The movement of the monitoring device 3 may be controlled by a program. In this case, it is preferable to control (program) so that it moves to a predetermined position at a predetermined time for monitoring and returns to the return point after the monitoring is completed. Also, when a decrease in the remaining battery level of the monitoring device 3 is detected, it is also preferable to control it to move to a location where there is a power supply means. Note that the monitoring device 3 may be operated from the outside of the housing 11 by remote control.

[0034] The power unit used to move the drive unit 33 usually converts electrical energy into power energy, such as an electric motor or a motor. It is preferable to transmit the power generated by the power unit to the wheels serving as drive wheels via a drive shaft to enable the main body 31 to move, but other modes may also be acceptable.

[0035] Although it is not essential to configure the monitoring device 3 to include a communication unit, it is preferable to configure it to include a communication unit. The communication unit is preferably capable of communicating information regarding the drive device and events or data measured, detected, or photographed by the monitoring unit 32. For example, it may communicate with a communication device provided inside or outside the electric and electronic equipment storage box 1.

[0036] In the example shown in FIG. 3, the monitoring device 3 includes a drive unit 33 on the running side and a monitoring unit 32 on the non-running side. The monitoring device 3 can move to various locations by running, but when an event that hinders running occurs (for example, an obstacle blocking the path or an abnormality in the drive unit 33 or the monitoring unit 32), it is preferable to stop the monitoring operation, communicate the event by a communication device, and be programmed in advance to return to the return point. Also, when running on the rail 7, it may be provided with a brush or the like capable of sweeping dust and dirt on the rail 7 during running to prevent an event that hinders running in advance.

[0037] Rather than running on the rail 7 attached to the members constituting the housing 11, it is conceivable that the monitoring device 3 runs on the members constituting the housing 11. More specifically, it is conceivable to run on the ceiling surface, left and right side surfaces, front and rear side surfaces, bottom surface of the housing 11, the door 12, columns, frames, members spanning between frames, etc. In this case, if the configuration is such that the first wheel 33a1 contacts the members constituting the housing 11, it becomes possible to run on the members constituting the housing 11 by transmitting the power created by the power unit to the first drive shaft. In this case, the monitoring device 3 may or may not move along a predetermined path.

[0038] When the monitoring device 3 is configured to run on the rail 7 installed on the members constituting the housing 11, in addition to the first wheel 33a1 located on the running side of the monitoring device 3, a second wheel 33a2 is provided inside the main body 31, and it is preferable to adopt a structure in which the rail 7 is sandwiched between the first wheel 33a1 and the second wheel 33a2. Regarding the power created by the power unit, it suffices to be transmissible to at least one of the first wheel 33a1 and the second wheel 33a2 to enable movement.

[0039] Here, an explanation will be given regarding the rail 7 that determines the running path of the monitoring device 3. The rail 7 can make the monitoring device 3 run at a position separated from the members constituting the housing 11. To enable such a thing, the rail 7 typically includes a support portion 71 which is one end having an installation surface 75, a running portion 72 which is the other end having a running surface 76, and a connecting portion 73 which is the part connecting the support portion 71 and the running portion 72.

[0040] Among the rails 7, in the case of an integrated rail having the support portion 71, the running portion 72, and the connecting portion 73 in one member, a rail with a substantially I-shaped cross-section is a typical example. It is installed on the installation surface 75 provided at one end, and typically, the monitoring device 3 runs on the running surface 76 provided at the other end. Note that the width of the connecting portion 73 is narrower than the widths of the support portion 71 and the running portion 72.

[0041] The rail 7 does not necessarily have to be limited to the above-described form. For example, the rail 7 shown in FIG. 6 is a separable rail in which a running part 72 having a running surface 76 and a support part 71 for supporting the running part 72 are configured to be separable. In the example shown in FIG. 6, the support part 71 is installed in the housing 11 with a predetermined interval. With such a configuration, it becomes possible to reduce the weight of the rail 7 and suppress the load on the housing 11.

[0042] In this example, the connection between the running part 72 and the support part 71 is performed by a connecting part 73 extending to the side opposite to the installation surface 75 of the support part 71, but the connecting part 73 and the running part 72 may be fixed by a fastening tool such as a screw. Note that the width of the connecting part 73 is narrower than the widths of the support part 71 and the running part 72.

[0043] Note that whether it is an integral rail or a separable rail, the installation surface 75 may be installed on any object such as the surface of the housing 11, the frame constituting the housing 11, or the attachment member attached to the housing 11.

[0044] Rails 7 of various lengths and various shapes are manufactured, and it is preferable that a plurality of these rails 7 are combined to form a running route. Hereinafter, an example of a separable rail will be mainly described, but these descriptions generally also apply to an integral rail. Further, when a running surface 76 is formed by processing a part of the member constituting the housing 11 into a shape similar to that of the running part 72 of the rail 7 and the monitoring device 3 is made to run, it also generally applies.

[0045] Next, the movement of the monitoring device 3 will be described. First, the movement in a linear or planar manner (where the movement range of the monitoring device 3 has a one-dimensional or two-dimensional spread) will be described. In a typical case where the rail 7 is installed such that the running surface 76 is positioned on the upper side and the monitoring device 3 is moved horizontally (moved with the rail 7 positioned below the monitoring device 3), an example of the structure can be that the first wheel 33a1 is brought into contact with the running surface 76 of the rail 7 and runs. In this case, for example, the monitoring device 3 can be made movable by transmitting the power generated by the power unit to the first wheel 33a1. In addition, in order to prevent the monitoring device 3 from falling off the rail 7, it is preferable to provide a wall extending from the running surface 76 of the rail 7 or the like and sandwich the monitoring device 3 with a plurality of walls.

[0046] Next, the movement in which the movement range of the monitoring device 3 has a three-dimensional spread will be described. When the monitoring device 3 moves three-dimensionally inside or on the outer surface of the housing 11, the rail 7 is installed over a plurality of surfaces. For this reason, the rail 7 may be arranged not only with the running surface 76 positioned at the upper part but also with the running surface 76 positioned at the lower part of the rail 7, or the running surface 76 of the rail 7 may be installed so as to extend in the vertical direction. That is, there are various installation modes of the running surface 76, and the monitoring device 3 running on it will also run in various directed states.

[0047] In this way, in the running process, the positional relationship between the monitoring device 3 and the rail 7 can change, such as when the monitoring device 3 is positioned above the rail 7, when it is positioned below the rail 7, or when it is horizontally adjacent to the rail 7. Of course, depending on the installation mode of the rail 7, not all of these can occur, but changes in two of the above-mentioned cases often occur.

[0048] When installing such that the running surface 76 is positioned above the rail 7, the monitoring device 3 may be placed on top of the rail 7 so that the drive wheels are brought into contact with the running surface 76 and can move. However, even in this case, the monitoring device 3 may still fall off the rail 7. Further, when the rail 7 extends in the vertical direction, it is difficult to move the monitoring device 3 as described above. Due to such circumstances, the monitoring device 3 of the embodiment is configured to have a function of preventing detachment from the rail 7.

[0049] In the embodiment, the detachment prevention function can be exerted by the arrangement structure of the portion of the monitoring device 3 that can come into contact with the rail 7. More specifically, the detachment prevention function can be exerted by arranging a member that can rotate while in contact with the rail 7.

[0050] In the example shown in FIGS. 4 and 5, the detachment prevention function can mainly be exerted by the wheels. In this example, as the wheels, a first wheel 33a1 and a second wheel 33a2 are provided. The first wheel 33a1 is provided on the running side of the monitoring device 3 and is provided so as to be distributed in all four directions on the running side. More specifically, the first wheel 33a1 having a rotation axis formed in a direction orthogonal to the longitudinal direction of the rail 7 is configured to be able to sandwich the rail 7.

[0051] Note that in this example, when the monitoring device 3 is placed on the upper side of the horizontally extending rail 7, the first wheel 33a1 will be positioned below the running surface 76. This first wheel 33a1 does not necessarily always have to be in contact with the rail 7 and may be such that it comes into contact with the rail 7 when the monitoring device 3 moves or topples in the short-side direction of the rail 7.

[0052] Also, in this example, when the monitoring device 3 is placed on the upper side of the rail 7 extending in the horizontal direction, the second wheel 33a2 will be located above the running surface 76. The second wheel 33a2 is arranged on the side opposite to the running direction compared to the first wheel 33a1, and in the embodiment, it is provided inside the main body 31. The second wheel 33a2 and the running surface 76 of the rail 7 do not necessarily always contact each other, but by contacting, the monitoring device 3 can achieve smooth running.

[0053] As can be understood from the above, the first wheel 33a1 and the second wheel 33a2 are structured such that they can be located on opposite sides around the running portion 72 of the rail 7, and the running portion 72 of the rail 7 can be interposed between the first wheel 33a1 and the second wheel 33a2. Note that it is not necessary for both the first wheel 33a1 and the second wheel 33a2 to always contact the rail 7, and for the wheels that are not in contact, they may come into contact when the orientation of the monitoring device 3 is changed.

[0054] In the above example, the rail 7 can be pinched from two different directions by pinching the rail 7 between the first wheels 33a1 and further between the first wheel 33a1 and the second wheel 33a2. More specifically, by pinching the connecting portion 73 of the rail 7 between the first wheels 33a1 and further pinching the running portion 72 of the rail 7 between the first wheel 33a1 and the second wheel 33a2, the other pinching is performed in a direction orthogonal to one pinching direction (for example, the vertical direction) (for example, the horizontal direction). With such a configuration, it is possible to prevent the monitoring device 3 from falling off the rail 7.

[0055] When the monitoring device 3 of the embodiment is placed on the upper side of the rail 7 extending in the horizontal direction, for example, when the monitoring device 3 moves in the short-side direction of the rail 7, it is mainly suppressed by the first wheels 33a1 to prevent it from falling off. Also, for the rail 7 extending in the vertical direction, mainly by the first wheels 33a1 and the second wheels 33a2 sandwiching the rail 7, it is prevented that the monitoring device 3 falls off the rail 7. As can be understood from this example, it is preferable to be able to sandwich the rail 7 from a plurality of directions and suppress the falling off from the rail 7.

[0056] Incidentally, when the monitoring device 3 is placed on the upper side of the rail 7 extending in the horizontal direction, the second wheels 33a2 come into contact with the running surface 76 of the rail 7. In this example, the second wheels 33a2 are those to which the power from the power unit is transmitted, and by the second wheels 33a2 rotating, the monitoring device 3 can be made to run on the rail 7.

[0057] Also, in this example, when the monitoring device 3 is hung below the rail 7 extending in the horizontal direction, by bringing the first wheels 33a1 into contact with the surface located on the opposite side to the above example, smooth running can be realized. In this example, the first wheels 33a1 are those to which the power from the power unit is transmitted, and by the first wheels 33a1 rotating, the monitoring device 3 can be made to run on the rail 7.

[0058] However, when either the first wheels 33a1 or the second wheels 33a2 are not those to which the power from the power unit is transmitted, if the wheel to which the power is transmitted moves away from the running part 72, there is a possibility that smooth running cannot be realized. For example, when the rail 7 is installed so as to extend in the vertical direction and the monitoring device 3 is to be made to run upward, there is a possibility that one or both of the first wheels 33a1 and the second wheels 33a2 move away from the running part 72 of the rail 7. To avoid such a situation, for at least one of the first wheels 33a1 or the second wheels 33a2, a spring-like member such as a suspension that presses against the running part 72 of the rail 7 may be connected so as to maintain contact of the wheels with the rail 7.

[0059] However, depending only on those structures, it may be difficult to travel upward in the vertical direction. Therefore, in the examples shown in FIGS. 4 and 5, the second wheel 33a2 is formed to include a gear portion 33aa and a tread portion 33ab. The rail 7 is provided with uneven portions 77 that mesh with the gear portion 33aa. By climbing while meshing the gear portion 33aa with the uneven portions 77, smooth travel upward in the vertical direction can be realized (see FIG. 7). Note that it may be possible not to provide the tread portion 33ab, but if the tread portion 33ab is provided, it becomes possible to select various traveling methods.

[0060] As can be understood from this example, it is preferable that the monitoring device 3 has a configuration including a gear portion 33aa capable of meshing with the uneven portions 77 provided on the rail 7 and a tread portion 33ab capable of traveling on the upper surface of the rail 7 on at least one of the wheels provided in the drive unit 33. In this way, for example, horizontal movement can be performed using the tread portion 33ab, and upward and downward movement can be performed using the gear portion 33aa.

[0061] Also, by using a spring-like member to press the first wheel 33a1 or the second wheel 33a2 against the traveling portion 72 of the rail 7 while meshing the gear portion 33aa with the uneven portions 77, smoother travel can be achieved. This applies not only when traveling upward in the vertical direction but also when the monitoring device 3 travels in any direction. In the examples shown in FIGS. 4 and 5, the gear portion 33aa is sandwiched from both sides by the tread portion 33ab, but the number and positional relationship of the gear portion 33aa and the tread portion 33ab are not limited to this example.

[0062] Regarding the shape of the rail 7, the preferable shape varies depending on the size of the gear portion 33aa that constitutes the second wheel 33a2. When the diameter of the gear portion 33aa is larger than the diameter of the tread portion 33ab (see FIGS. 4 and 5), it is preferable to provide a groove portion 79 for inserting the gear portion 33aa at a position corresponding to the gear portion 33aa on the running surface 76 of the rail 7 so as to avoid the gear portion 33aa coming into contact with the running surface 76 or the like at unnecessary locations. The groove portion 79 is preferably formed to a depth such that the gear portion 33aa is in a floating state (not in contact with the bottom of the groove portion 79) when the tread portion 33ab is in contact with the running surface 76.

[0063] When the running surface 76 is located on the upper surface of the rail 7, it is not always necessary to form the uneven portion 77 in the groove portion 79. However, when the monitoring device 3 runs at a position parallel to the rail 7 in the horizontal direction (when the rail 7 extends in the vertical direction) or when the running surface 76 is located at the lower part of the rail 7, it is preferable to form the uneven portion 77 in the groove portion 79. By doing so, when the monitoring device 3 runs, the gear portion 33aa and the uneven portion 77 can run while meshing with each other, so that it can run smoothly.

[0064] At this time, it may be possible to run more smoothly by further bringing the tread portion 33ab into contact with the running surface 76. As described above, this can be realized by pressing the first wheel 33a1 or the second wheel 33a2 against the running portion 72 of the rail 7 by means of a suspension or the like.

[0065] In addition, dust, dirt, water, etc. may accumulate on the rail 7. Regarding the dust, dirt, water, etc. deposited on the running surface 76, it may be removed by a brush or the like provided in the monitoring device 3. However, it may be difficult to remove the dust, dirt, water, etc. that have accumulated in the groove portion 79 and the uneven portion 77.

[0066] Therefore, it is preferable that the rail 7 has a structure in which dust, dirt, water, etc. do not easily accumulate. For example, by forming holes in the groove portion 79, the uneven portion 77, etc. of the rail 7, dust, dirt, water, etc. can pass through the holes and not accumulate. In the case of an integral rail, by also providing holes in the connecting portion 73 so as to communicate with the holes provided in the running portion 72, dust, dirt, water, etc. that have entered through the holes in the running portion 72 may be discharged from the holes in the connecting portion 73.

[0067] On the other hand, there is a possibility that dust, dirt, water, etc. may clog the holes provided in the rail 7. In particular, when the holes provided in the uneven portion 77 are clogged, there is a possibility that the gear portion 33aa and the uneven portion 77 may not mesh and the monitoring device 3 may not run smoothly. Therefore, it is preferable to adopt a structure in which a part of the gear portion 33aa is inserted into the holes provided in the uneven portion 77 so that the monitoring device 3 runs while the gear portion 33aa pushes out the dust, dirt, water, etc. clogged in the holes.

[0068] When the diameter of the gear portion 33aa is smaller than the diameter of the tread portion 33ab (see FIGS. 8 and 9), usually, the tread portion 33ab contacts the running surface 76 or the like. Therefore, when the running surface 76 is positioned on the upper surface of the rail 7, it is assumed that the tread portion 33ab and the running surface 76 are in contact and move. At this time, the gear portion 33aa is in a floating state.

[0069] On the other hand, when the rail 7 changes from a state of extending in the horizontal direction to a state of extending in the vertical direction, for example, an uneven portion 77 can be provided at a position corresponding to the gear portion 33aa in the running portion 72 of the rail 7, and a recessed portion 78 formed by recessing the running surface 76 by a certain amount can be formed (see FIG. 10). In this way, it is possible to suppress the shaking of the monitoring device 3 even when the gear portion 33aa and the uneven portion 77 start to mesh. Note that by changing the length of the rail 7 in the short side direction, it is also possible to form a rail 7 in which the recessed portion 78 is not provided in the running portion 72 and only the uneven portion 77 is formed in a part of the running portion 72.

[0070] When providing the recessed portion 78 in the running gear 72, if the recessed portion 78 is formed by recessing to such an extent that the tread surface portion 33ab does not come into contact in a state where the gear portion 33aa and the uneven portion 77 are engaged, it becomes possible to run smoothly. However, it is also preferable to provide the recessed portion 78 to such an extent that the tread surface portion 33ab comes into contact in a state where the gear portion 33aa and the uneven portion 77 are engaged. By doing so, not only does the gear portion 33aa engage with the uneven portion 77, but also the tread surface portion 33ab comes into contact with the recessed portion 78, making it possible to run smoothly.

[0071] Incidentally, the monitoring device 3 is required to stop at a predetermined position of the rail 7 in order to monitor events occurring in the electric and electronic equipment or the housing 11 and the periphery of the housing 11. However, in a case where the rail 7 is installed so as to extend in the vertical direction, even if the gear portion 33aa and the uneven portion 77 are engaged, there is a possibility that it may move in the direction of gravity without stopping. For this reason, in a state where power is not being transmitted from the power unit, it is preferable that the drive unit 33, particularly the drive wheels, have a structure that does not rotate. Further, it is preferable to provide a stopping means for stopping the movement when the monitoring device 3 is in a stopped state.

[0072] For example, it can be exemplified that the stopping means has a structure that fits into the uneven portion 77 in a stopped state, and the downward movement is restricted by the engagement between the gear portion 33aa and the uneven portion 77 and the fitting between the stopping means and the uneven portion 77. Also, the stopping means may have a structure that increases the frictional force with the rail 7 when stopped. For example, a structure that increases the frictional force by more strongly sandwiching the rail 7 with the first wheel 33a1 or the first wheel 33a1 and the second wheel 33a2 can be exemplified. In addition, the stopping means may be anything as long as it has a structure that can stop the monitoring device 3.

[0073] The monitoring device 3 preferably includes a monitoring unit 32, a driving unit 33, a power unit, and a communication unit. However, it may also be configured to have various other functions. However, if many functions are added to the monitoring device 3, there are concerns that manufacturing costs, maintenance costs, etc. will increase, and the size of the monitoring device 3 will become larger. Therefore, auxiliary means 8 for assisting the attached electrical and electronic devices is preferably provided on the rail 7 for attaching the electrical and electronic devices to the housing 11 of the electrical and electronic device storage box 1 in which the electrical and electronic devices are stored inside the housing 11, or so as to face the rail 7. By configuring the rail system in this way, the rail system attached to the electrical and electronic device storage box 1 can assist the functions of the electrical and electronic devices attached to the housing 11 of the electrical and electronic device storage box 1.

[0074] Examples of the auxiliary means 8 include a function (communication means) for relaying the communication of the monitoring device 3, a function (power supply means) for supplying power to the monitoring device 3, a function (position grasping means) for grasping the position of the monitoring device 3, a function (switching means 89) for switching the traveling route of the moving monitoring device 3, and the like.

[0075] Note that the auxiliary means 8 provided in the rail system is not limited to assisting the monitoring device 3. Any means that can assist the attached electrical and electronic devices may be used. However, the electrical and electronic devices assisted by the rail system are preferably installed so as to be movable on the rail 7. Further, the auxiliary means 8 preferably includes at least one of a means for supplying power to the electrical and electronic devices, a means for relaying the communication of the electrical and electronic devices, and a means for grasping the position of the electrical and electronic devices, but it may also include other means.

[0076] Here, an example of providing communication means as the auxiliary means 8 on the rail 7 will be described. It is conceivable that the monitoring device 3 is provided with a communication unit and is configured to communicate data and information measured, detected, or photographed by the monitoring unit 32. In this case, the communication destination may be a device outside the housing 11. However, in such a case, it is necessary to make the communication unit of the monitoring device 3 high-performance. Therefore, communication means is provided on the rail 7 so as to be communicable with the communication unit of the monitoring device 3.

[0077] As the installation location of the communication means, any of the running part 72, the connecting part 73, and the supporting part 71 of the rail 7 may be used. However, by providing a plurality of communication means on the rail 7, it becomes possible to always be in a state of being able to communicate with the moving monitoring device 3.

[0078] Also, a communication means may be provided on the rail end structure 8a provided adjacent to the longitudinal end of the rail 7, so that when the monitoring device 3 approaches the communication part, all the measured, detected, or photographed data and information stored in a certain amount by the monitoring device 3 are communicated to the communication means. In this case, since communication is not performed every time measurement, detection, or photographing is performed by the monitoring unit 32, it is possible to suppress the electricity used by the monitoring device 3. Note that the rail end structure 8a in the example of FIG. 11 may have functions other than communication as the auxiliary means 8 provided so as to face the rail 7.

[0079] Communication to the outside of the housing 11 may be performed by each communication means provided so as to face the rail 7 or the rail 7, or a communication device that aggregates data and information from each communication means may be provided inside the housing 11, and communication may be performed from the communication device to the outside of the housing 11. That is, the communication means provided so as to face the rail 7 or the rail 7 may be used as a repeater. Of course, when the monitoring device 3 is near the communication device, it may directly communicate from the communication part of the monitoring device 3 to the communication device.

[0080] [[ID=X]]

[0081] ​As can be understood from these descriptions, when a plurality of communication devices such as the communication unit of the monitoring device 3, the communication means of the rail 7, and the communication device provided inside the housing 11 are provided, the communication range of each communication device can be shortened, and the cost can be reduced.

[0082] Each of the above-described communication devices is not only used to transmit the data, information, measured, detected, or photographed by the monitoring unit 32 of the monitoring device 3 to the outside of the housing 11, but may also be used to transmit various instructions sent from the outside of the housing 11 and received by the monitoring device 3.

[0083] The various instructions include those that change the timing of measurement, detection, or photography by the monitoring unit 32, those that change the range of measurement, detection, or photography, etc., those that change the functions of the monitoring unit 32, those that change the position of the monitoring device 3, those that change the moving speed of the monitoring device 3, etc., and those that change the drive unit 33 or the power unit. Any instructions are acceptable. Further, the movement, measurement, detection, photography, etc. of the monitoring device 3 may be remotely operable.

[0084] Next, an example of providing a power supply means on the rail 7 will be described. The monitoring device 3 of the embodiment includes a power unit, and is capable of moving by transmitting power from the power unit to the drive unit 33. The power unit is a motor or the like that provides kinetic energy and requires electrical energy. The electrical energy needs to be supplied from outside the monitoring device 3. Therefore, in the embodiment, a power supply means is provided on the rail 7 to enable power supply to the power unit of the monitoring device 3.

[0085] As the installation location of the power supply means, any of the running part 72, the connecting part 73, and the supporting part 71 of the rail 7 may be used. However, by providing a plurality of them on the rail 7, it is preferable to always or frequently enable power supply to the moving monitoring device 3.

[0086] Alternatively, a location where power can be supplied to the monitoring device 3 may be provided at a predetermined location limited to one or several locations. For example, a charging spot where power can be supplied to the monitoring device 3 may be provided at a predetermined position of the rail end structure 8a or the rail 7, and power may be supplied when the monitoring device 3 approaches the charging spot. By doing so, the frequency of power supply can be reduced, resulting in power saving. The charging spot may have, for example, a tunnel shape that covers the monitoring device 3 traveling along the rail 7 at a predetermined location (see Fig. 11). In this case, both movement and power supply can be achieved. Note that the monitoring device 3 may stop and be powered inside the charging spot. Also, although the tunnel structure 8b shown in Fig. 11 is used as a charging spot, the tunnel structure 8b may be provided as auxiliary means 8 facing the rail 7 and may have functions other than power supply.

[0087] Next, an example of providing a position detection means in the rail system will be described. When monitoring is performed by the monitoring unit 32, by detecting the position of the monitoring device 3, it becomes possible to accurately detect an abnormal location of the box 1 for storing electrical and electronic equipment. Therefore, it is preferable to enable the detection of the position information of the monitoring device 3, such as by providing an IC chip having position information on the rail 7. The position detection function for detecting the position of the monitoring device 3 may be related to communication means provided on the rail 7 or the like, and the communication means of the rail 7 that communicates with the communication unit of the monitoring device 3 may communicate position information such as the position of the monitoring device 3 and its own position together with data and information from the monitoring device 3, so that the position of the monitoring device 3 can be detected. Also, by communicating position information from the communication means of a plurality of rails 7, it may be possible to detect a more accurate position of the monitoring device 3.

[0088] Next, an example of providing a switching means 89 on the rail 7 will be described (see Fig. 12). The monitoring device 3 travels on the rail 7. However, when it travels only on one rail 7, the range and targets that can be measured, detected, or photographed are limited. Therefore, it is preferable to form a plurality of travel routes on the rail 7 provided inside or on the outer surface of the housing 11 and give the rail 7 the function of being able to switch the travel route. For example, a switching point where two rails 7 can move in conjunction with each other is provided so that the travel route can be selected.

[0089] The auxiliary means 8 provided on the rail 7 or so as to face the rail 7 is not limited to the above-mentioned communication means, power supply means, position grasping means, and switching means 89, and may be any means that assist the monitoring device 3, and they may be attached to the rail 7 as one unit.

[0090] Hereinafter, more specific examples will be given for explanation. First, an example of a structure in which a rail 7 is installed inside a cubicle-type high-voltage power receiving facility (hereinafter referred to as a cubicle) and the monitoring device 3 can be moved will be described. The cubicle has a structure with a relatively large internal space so that people can enter and work inside during inspections and the like. More specifically, electrical and electronic devices such as a circuit breaker 61 near the ceiling surface, a transformer 62 near the bottom surface, and a disconnector 63 on the front side are provided, but the electrical and electronic devices are arranged at a certain distance inside the housing 11 (see Figs. 13 and 14). Here, it is an example of providing a rail system inside the housing 11 of such a cubicle.

[0091] In the examples shown in FIGS. 13 and 14, the rail 7 is provided to form two travel routes, and the monitoring device 3 travels along each travel route. One of the two travel routes is for monitoring the entire housing 11 and the transformer 62, and the other is for monitoring the circuit breaker 61 and the disconnector 63 arranged on the front surface of the housing 11. Note that the formation of the travel routes is arbitrary, and it may be possible to monitor the entire housing 11 and all the electrical and electronic devices with a single travel route, or the objects to be monitored may be different for each travel route.

[0092] Alternatively, travel routes may be formed for each monitoring device 3 provided with monitoring units 32 that monitor different events. In this case, for example, a travel route for monitoring the temperature of the entire housing 11 by running a monitoring device 3 equipped with a temperature sensor and a humidity sensor, and a travel route for monitoring the sound of specific electrical and electronic devices by running a monitoring device 3 equipped with a sound sensor and a camera may be formed.

[0093] Of course, a plurality of monitoring devices 3 may travel on a single travel route. In that case, it is preferable to provide an avoidance point in the middle of the travel route so that the plurality of monitoring devices 3 can pass by each other.

[0094] In the examples shown in FIGS. 13 and 14, both of the two travel routes start (end) near the bottom surface on the front side of the housing 11, and the rail 7 extends in various directions of front-back, left-right, up-down, and ends (ends) near the bottom surface on the front side of the housing 11. There is no problem with the locations of the start and end points of the rail 7 at arbitrary positions, but it is preferable to install the rail 7 in consideration of the maintainability of the monitoring device 3. For example, by installing a part of the rail 7 at a position where it can face the opening of the housing 11, the convenience of maintaining the monitoring device 3 can be improved.

[0095] In the example shown in FIGS. 13 and 14, by installing at least a part of the rail 7 on the front side where the door 12 that can cover the opening of the housing 11 is provided, maintenance of the monitoring device 3 can be performed without entering the inside of the housing 11. At this time, the part of the rail 7 installed at a position where it can face the opening of the housing 11 can be anything, but it is preferably a detachment point of the monitoring device 3 (a place where the monitoring device 3 can be detached from the rail 7), a return point of the monitoring device 3 (a place where the monitoring device 3 returns after a series of operations), a charge spot used for power supply of the monitoring device 3, and the like. As can be understood from the example of the charge spot, it is preferable to provide auxiliary means 8 such as power supply means at a position where it can face the opening of the housing 11.

[0096] Also, regarding the position where it can face the opening of the housing 11, any position is acceptable as long as it is a position where it is not necessary to enter the inside of the housing 11 when accessing the monitoring device 3, but it is preferably a position where it can face when the door 12 is opened.

[0097] As can be understood from these descriptions, the rail 7 is preferably installed across a plurality of surfaces of the housing 11, and at least a part of the rail 7 is installed at a position where it can face the opening of the housing 11.

[0098] When providing the rail 7 inside the housing 11, it is necessary to install it considering the distance from conductors such as electric and electronic devices or electric wires connecting electric and electronic devices to each other, and there is a possibility that the monitoring device 3 cannot be brought close to the vicinity of the electric and electronic devices. In such a case, a part of the monitoring device 3 (such as the monitoring unit 32 or the monitoring unit 32 and the main body 31) may be moved separately from the entire monitoring device 3 so that it can be brought close to the vicinity of the electric and electronic devices. For example, some sensors or cameras of the monitoring unit 32 may be made movable with respect to other parts of the monitoring unit 32.

[0099] In addition, when the distance from the electrical and electronic equipment or a conductor such as an electric wire connecting the electrical and electronic equipment cannot be sufficiently maintained, the rail 7 and the monitoring device 3 may be covered with an insulating member.

[0100] Next, an example of a structure in which the rail 7 is installed on the outer surface of the cubicle and the monitoring device 3 is made movable will be described. In this example, the rail 7 is provided on the outer surface of the cubicle (see FIG. 15). More specifically, the rail 7 is arranged on the side surface, ceiling surface, etc. that constitute the housing 11 of the cubicle. In this example, the running route formed on the side surface of the housing 11 is mainly provided for monitoring the side surface, door 12, etc., and the running route formed on the ceiling surface is mainly provided for monitoring the periphery of the housing 11. When the rail 7 is provided on the outer surface of the housing 11, there are concerns about rain, wind, etc. Therefore, for example, the rail 7 and the monitoring device 3 may be covered by a waterproof structure.

[0101] In the examples shown in FIGS. 14 and 15, the ceiling 14 of the cubicle protrudes beyond the door 12, and the eaves portion 15 is formed. Therefore, if the rail 7 is installed below the eaves portion 15, it is possible to protect the monitoring device 3 and the rail 7 from rain. In addition, a ventilation port is provided below the eaves portion 15. It is preferable to process a part of this ventilation port and install the rail 7 so as to pass through this part. In this way, a running route connecting the inside and the outside of the housing 11 can be formed, and it is possible to monitor both the inside and the outside of the housing 11 with one monitoring device 3.

[0102] Next, an example of installing the rail 7 on a distribution board, switchboard, control panel, and system rack will be described. The electrical and electronic equipment storage box 1 includes, in addition to the cubicle, a distribution board, switchboard, control panel, system rack, etc. An example of installing the rail 7 on these will be described next.

[0103] For example, a distribution board, a switchboard, a control panel, etc. are provided with a door 12 on the front side so as to be able to close the opening of the housing 11 having upper and lower surfaces, left and right surfaces, and a back surface, and electrical and electronic devices are mainly attached to the back side. Note that the rail 7 may be installed on any surface of the housing 11, but by installing the rail 7 particularly on the back surface, it becomes possible to efficiently monitor the electrical and electronic devices.

[0104] Also, inside the housing 11, a protection plate is provided to prevent electrical accidents (such as electric shock accidents) caused by contact with electrical and electronic devices. Since this protection plate is provided at a position that faces the door 12 when the door 12 is closed, the protection plate is exposed when the door 12 is opened. Therefore, for example, by performing processing on a part of the protection plate and arranging the rail 7 so as to be exposed from the back surface side to the front surface side of the protection plate, the maintenance of the monitoring device 3 can be performed without opening the protection plate, and the convenience of maintenance can be improved.

[0105] Also, the system rack includes a mounting member for mounting electrical and electronic devices inside the housing 11. By installing the rail 7 on this mounting member, it becomes possible to efficiently monitor the electrical and electronic devices. For example, by forming a route so that the monitoring device 3 can travel between the electrical and electronic devices attached to the mounting member, it becomes possible to more accurately monitor the electrical and electronic devices. For example, by running a monitoring device 3 equipped with a temperature sensor between the electrical and electronic devices, the heat around the electrical and electronic devices can be monitored, and the failure of the electrical and electronic devices can be prevented.

[0106] In the above example, the example in which the monitoring device 3 travels on the rail 7 fixed to the surface constituting the housing 11 is mainly shown, but it is not necessary to be limited to such a mode. In the following example, the case where the rail 7 on which the monitoring device 3 travels is made movable will be described.

[0107] For example, at least two support members 91 are arranged in parallel, and at least one rail 7 is movably installed so as to span the two support members 91. For example, the two support members 91 are arranged parallel to the left and right sides of the housing 11, and one rail 7 is installed parallel to the front and rear sides so as to be movable in the front-rear direction.

[0108] Alternatively, one support member 91 may be linear and arranged parallel to the side of the housing 11, or one support member 91 may be bent and arranged so as to span a plurality of surfaces of the housing 11. The support member 91 or the rail 7 may be composed of two or more. For example, by configuring the support member 91 with two or more, it is possible to improve the strength. Also, by configuring the rail 7 with two or more, it is possible to increase the types of monitoring devices 3 traveling on the rail 7 and to monitor by dividing the monitoring area.

[0109] In the example shown in FIG. 16, it is a configuration including two support members 91 and one rail 7 installed on the ceiling surface of the housing 11. In order to suppress the types of members to be prepared, it is preferable to use members having the same structure for the support member 91 and the rail 7. Further, when providing a moving member 95 that enables the rail 7 to move along the support member 91, it is preferable to form the moving member 95 with reference to the structure of the monitoring device 3. That is, the moving member 95 preferably forms the main outer shape by processing a part of the same member as the main body 31 of the monitoring device 3 into a shape capable of fixing the rail 7, and has a structure including a drive unit 33.

[0110] In the example shown in FIG. 16, the moving member 95 is provided on each support member 91 so that the rail 7 can move along the support member 91, and further, the monitoring device 3 is movably provided on the rail 7. As a result, the movement in the front-rear direction is enabled by the movement of the rail 7 with respect to the support member 91, and the movement in the left-right direction is enabled by the movement of the monitoring measure with respect to the rail 7. In this way, the movement range of the monitoring device 3 can be made to have a two-dimensional spread.

[0111] Further, separately from the movement of the entire monitoring device 3, only a part of the monitoring device 3 may be formed to be movable. For example, a string or a rope may be attached to the monitoring unit 32 to make the monitoring unit 32 movable with respect to the main body 31, or a string or a rope may be attached to some sensors or cameras of the monitoring unit 32 to make the sensors or cameras movable with respect to other parts of the monitoring unit 32.

[0112] In the example shown in FIG. 16, the rail 7 has the traveling unit 72 installed on the lower side of the rail 7, and the monitoring device 3 is arranged so as to be located below the rail 7. Further, the monitoring unit 32 separated from the main body 31 of the monitoring device 3 or a part of the monitoring unit 32 is suspended in the direction of the bottom surface of the housing 11. That is, by forming a part of the monitoring device 3 to be separable from the main body 31, movement in the vertical direction is enabled. For this reason, the monitoring unit 32 and the like of the monitoring device 3 can realize three-dimensional movement within the housing 11.

[0113] In the above example, the rail 7 is moved linearly, but the movement of the rail 7 does not have to be linear. For example, the rail 7 may be rotated. In the example shown in FIG. 17, the rail 7 is made rotatable by a rotating member 98 capable of rotating the rail 7. In the example shown in FIG. 17, the center of the rail 7 is connected to the rotating member 98, but a structure in which the end of the rail 7 is installed on the rotating member 98 may also be used.

[0114] In the example shown in FIG. 17, the rotating member 98 is installed on the ceiling surface of the housing 11, and the rail 7 is fixed to the rotating member 98. By rotating the rail 7 by the rotating member 98, the direction of the rail 7 can be changed in the front-rear and left-right directions. Further, the monitoring device 3 can travel on the rail 7. By these means, the monitoring device 3 can be moved in the front-rear direction and the left-right direction.

[0115] Even in such an example, similar to the above-described case, by forming a part of the monitoring device 3 to be separable from other parts, movement in the vertical direction may be enabled. If so, the monitoring unit 32 and the like can realize three-dimensional movement within the housing 11.

[0116] The present invention has been described above by taking the embodiments as examples. However, the present invention is not limited to the above embodiments and can be in various forms. For example, a monitoring device may be fixed to a rail provided with auxiliary means.

[0117] Also, the auxiliary means does not necessarily have to face only the running surface that is the end surface located opposite to the mounting surface of the rail. For example, it may face a support portion or a connecting portion, or may face a surface on the side opposite to the running surface of the running portion.
