Hereinafter, the configuration of the TM branch office 10 and the configuration of the management center 50 will be described.

As shown in FIG. 1, the TM branch office 10 has fuses 1A, 1B, relays 1F, and 1G as a plurality of devices for acquiring water level, water pressure, and the like (device 1 when it is not necessary to distinguish each device). (Called) is provided. The moving unit 20 is movably provided in the TM branch office 10. The moving unit 20 is composed of a first acquisition unit 21 composed of a temperature sensor, an infrared sensor, etc. to acquire device information J1 and position information J3, and an abnormality information J2 composed of a voltage sensor, a current sensor, a resistor, and the like. It includes a second acquisition unit 22 for acquisition. Further, the TM branch office 10 outputs the device information J1, the position information J3, and the abnormality information J2 acquired by the mobile unit 20 to the management center 50 via the network N, and is based on a command from the management center 50. A first communication processing unit 5 that controls each device 1 is provided.

As shown in the perspective view of FIG. 2, each device 1 (fuse 1A, 1B, relay 1F, 1G, etc.) and the first communication processing unit 5 are housed in the housing 8 of the TM branch office 10. .. Further, these plurality of fuses and relays are arranged together as a fuse portion and a relay portion, respectively. In the figure, for convenience, two fuses 1A and 1B are shown for fuses, and two relays 1F and 1G are shown for relays, but the number and types of devices 1 actually used in the TM branch office 10 are limited to this. It is not something that can be done.
Further, in the housing 8, a plurality of rails 7 are installed in a grid pattern so as to face each device 1 housed in the housing 8. The movement of the moving unit 20 in the TM branch office 10 is performed by moving on the rail 7.
Hereinafter, when the position of the moving portion 20 in the housing 8 and the position of each device 1 are shown, one point in the housing 8 is set as the reference coordinate (X, Y: 0,0), and the position is on the X, Y plane. Shown using coordinates.

As shown in FIG. 1, the management center 50 is provided with a second communication processing unit 51. The second communication processing unit 51 acquires the device information J1, the position information J3, and the abnormality information J2 acquired in the TM bureau section 10 via the network N, and controls each device 1 of the TM bureau section 10. It outputs a command to do so. The device information J1, the position information J3, and the abnormality information J2 acquired by the second communication processing unit 51 are input to the processing unit 30. The processing unit 30 uses the abnormality determination data 31 used for determining the abnormality of the device information J1, the device correspondence data 32 for identifying the device 1 from the position information J3, and the abnormality type data 33 used for determining the abnormality information J2. , The device information J1 and the abnormality information J2 are analyzed. The processing result in the processing unit 30 is displayed on the display unit 40.

Further, the processing unit 30 has predetermined movement route information K for moving the moving unit 20 within the TM branch office 10. Then, the movement of the moving unit 20 is performed according to the movement route information K designated by the processing unit 30.

Hereinafter, the processing in the maintenance device of the present embodiment will be described with reference to the drawings.
FIG. 3 is a flow chart showing processing in the maintenance device of the present embodiment.
FIG. 4 is a diagram showing a configuration example of device-compatible data 32 included in the processing unit 30 shown in FIG.
FIG. 5 is a diagram showing a configuration example of the abnormality type data 33 included in the processing unit 30 shown in FIG.
FIG. 6 is a diagram showing an overall image E of each device 1 displayed on the display unit 40 shown in FIG. 1 and a processing result in the processing unit 30.

First, the processing of the maintenance device is started in a state where each device 1 of the TM branch office 10 is operating in order to monitor information such as water level and water pressure (step S1).
The moving unit 20 acquires device information J1 such as a temperature indicating the state of each device 1 at any time by the first acquisition unit 21 while moving on the rail 7 according to the moving path information K in the TM branch office 10. At this time, each time the moving unit 20 acquires the device information J1, the position information J3 of the moving unit 20 at the time when the device information J1 is acquired is added to the acquired device information J1 (step S2). The position information J3 of the moving unit 20 indicates the moving distance (unit, m) from the reference coordinates (X, Y: 0, 0) on the X and Y coordinates.

The device information J1 and the position information J3 acquired by the moving unit 20 moving in this way are output to the management center 50 at any time via the first communication processing unit 5.

The second communication processing unit 51 of the management center 50 outputs the device information J1 acquired via the network N to the processing unit 30.
The processing unit 30 detects an abnormality in the device 1 based on the acquired device information J1 and the abnormality determination data 31 (step S3).

An example of the abnormality detection method in step S3 will be described.
For example, it is assumed that the acquired device information J1 is temperature information, and the abnormality determination data 31 is "abnormal at 80 ° C. or higher". In this case, if the temperature of the acquired device information J1 is lower than 80 ° C., the processing unit 30 determines that there is no abnormality (step S3, No). In this case, the processing unit 30 returns to step S2 and causes the moving unit 20 to continue acquiring the device information J1.
Further, when the temperature of the acquired device information J1 is 80 ° C. or higher, the processing unit 30 determines that “an abnormality has occurred” (step S3, Yes). In this case, the processing unit 30 causes the moving unit 20 to complete the acquisition of the device information J1.

When an abnormality is detected in step S3, the processing unit 30 determines the device 1 in which the abnormality has occurred based on the position information J3 added to the device information J1 in which the abnormality is detected and the device correspondence data 32. Is specified from among the plurality of devices 1 (step S4).

An example of the device identification method in step S4 will be described.
As shown in FIG. 4, the device correspondence data 32 identifies the device 1 for which the moving unit 20 has acquired the device information J1 from among the plurality of devices 1 based on the position information J3 added to the device information J1. Is. For example, it is assumed that the position information J3 of the moving unit 20 added to the device information J1 in which the abnormality is detected is the coordinates (X, Y: 0.4, 1.5). In this case, from the device correspondence data 32, it can be seen that the device 1 corresponding to the position information J3 (X, Y: 0.4, 1.5) is the fuse 1B. In this way, the processing unit 30 identifies the fuse 1B in which the abnormality has occurred from among the plurality of devices 1.

Next, the processing unit 30 identifies and shows the fuse 1B in which the abnormality has occurred on the display unit 40 (step S5).
As shown in FIG. 6, the display unit 40 displays the entire image E of each device 1 in the TM bureau unit 10, and the fuse 1B in which the abnormality has occurred is specified as an “abnormality”.
The entire image E may be a photograph of the overall configuration of the plurality of devices 1 in the TM branch office 10, or a drawing showing the overall configuration of the device 1.
Further, in the acquisition of the device information J1 in step S2, when the moving unit 20 is moved according to the moving path information K, the device 1 (fuse 1B) in which the abnormality has occurred is identified in the overall image E of the display unit 40, and the device 1 (fuse 1B) is identified. It is also possible to superimpose this movement route information K on the entire image E.

Next, the processing unit 30 causes the second acquisition unit 22 of the moving unit 20 to acquire the abnormality information J2 such as the voltage value, the current value, and the resistance value of the terminal in the fuse 1B in which the abnormality has occurred (step S6). The abnormality information J2 acquired in this way is output to the management center 50 via the first communication processing unit 5. The second communication processing unit 51 of the management center 50 outputs the abnormality information J2 acquired via the network N to the processing unit 30.

Next, the processing unit 30 determines the abnormality type of the fuse 1B in which the abnormality has occurred based on the acquired abnormality information J2 and the abnormality type data 33 (step S7).
An example of the abnormality type determination method in step S7 will be described.
As shown in FIG. 5, the abnormality type data 33 indicates the abnormality type related to the content of the acquired abnormality information J2 for each device 1. For example, it is assumed that the acquired abnormality information J2 is the voltage information at the terminal of the fuse 1B. In this case, when the acquired abnormality information J2 of the fuse 1B is "terminal voltage value 0V", the processing unit 30 determines that the abnormality type is "fuse blown" from the abnormality type data 33.

In this way, through the steps S1 to S7, the maintenance device identifies the device 1 (fuse 1B) whose temperature (device information J1) has abnormally risen from among the plurality of devices 1 possessed by the TM branch office 10. Further, the maintenance device determines the abnormality type (fuse blown) of the device 1 (fuse 1B) in which the abnormality has occurred.
The staff of the management center 50 performs the maintenance work of the TM branch office 10 based on the processing result by the maintenance device thus obtained.

Although the moving unit 20 has been described as moving on the rail 7 in accordance with the moving route information K in the TM bureau section 10 in step S2, it may move randomly on the rail 7. When the moving unit 20 randomly moves on the rail 7, the processing unit 30 does not have the moving route information K.
Further, in the above, an example in which the TM branch office 10 includes one mobile unit 20 is shown, but the present invention is not limited to this. A plurality of moving units 20 may be provided depending on the configuration of the TM bureau unit 10.

According to the maintenance device of the present embodiment configured as described above, the processing unit 30 is provided with the position information J3 of the moving unit 20 by the moving unit 20 provided so as to be movable in the TM branch office 10. Acquire the device information J1 of the device 1. Then, the maintenance device identifies the device 1 in which the abnormality has occurred from among the plurality of devices 1 based on the device information J1 to which the position information J3 is added. As a result, even if an abnormality occurs in a device 1 such as a fuse or a relay that does not have a self-abnormality determination function, the device 1 in which the abnormality has occurred can be quickly identified in the management center 50. Therefore, it is not necessary for the staff of the management center 50 to go to the TM branch office 10 to conduct a survey to identify the device 1. As a result, the time from the occurrence of an abnormality to the restoration of the TM branch office 10 can be significantly shortened without causing a time delay due to the ordering of the replacement device of the device 1. In this way, maintenance work can be made more efficient.

In addition, the replacement work of the specified device 1 is also performed remotely by the staff from the management center 50 using a robot arm or the like, so that the TM branch office 10 can perform the replacement work from the identification work of the device 1 in which the abnormality has occurred. It is also possible to do it without the staff going to.

Further, the moving unit 20 is configured to be movable within the TM branch office 10, and acquires the device information J1 of each device 1 while moving. Therefore, it is not necessary to individually provide a sensor for each device 1, and it is possible to reduce the cost and space.
Further, the maintenance device can determine the abnormality type of the device 1 in which the abnormality has occurred based on the abnormality type data 33. As a result, the maintenance device can give the staff of the management center 50 a guideline necessary for determining the replacement or repair of the device 1 in which the abnormality has occurred. As a result, the efficiency of business can be further improved.

Further, the moving portion 20 is installed on the rail 7 and moves in the TM branch portion 10. With such a simple configuration using the rail 7, the moving unit 20 can be moved within the TM branch office 10 to acquire the device information J1 of each device 1.
Further, the moving unit 20 can also move according to the predetermined movement route information K possessed by the processing unit 30. In this case, as compared with the case where the moving unit 20 randomly moves on the rail 7 and acquires the device information J1 of each device 1, the moving unit 20 moves in the TM branch office 10 without bias according to the moving route information K, and each moves. The device information J1 of the device 1 can be acquired.

Further, the device 1 in which the abnormality has occurred is identified and shown on the overall image E of the display unit 40. As a result, the staff of the management center 50 can visually and quickly grasp which part of the TM branch office 10 the device 1 has an abnormality, and can obtain a guideline for maintenance work.
Further, when the moving unit 20 moves in the TM branch office 10 according to the moving route information K, it is possible to display the moving route information K on the entire image E of the display unit 40. As a result, the staff of the management center 50 can visually and quickly grasp which part of the TM branch office 10 the mobile unit 20 moves, and can obtain a guideline for maintenance work.

In the above, the two-dimensional coordinates of X and Y are used as the position information J3. However, the present invention is not limited to this, and when the rail 7 is configured three-dimensionally, the three-dimensional coordinates of X, Y, and Z may be used as the position information J3. Further, the position information J3 may be indicated by using a method other than the coordinates.

Further, the configurations of the device correspondence data 32 and the abnormality type data 33 are not limited to the configurations shown above. The device correspondence data 32 may have a configuration in which the device 1 for which the moving unit 20 has acquired the device information J1 can be specified from among the plurality of devices 1 based on the position information J3 added to the device information J1. Further, the abnormality type data 33 may be any data that can identify the abnormality type related to the content of the acquired abnormality information J2.

Further, in step S3, the processing unit 30 has detected an abnormality in the device 1 using the abnormality determination data 31, but the processing unit 30 uses the storage device information in addition to the abnormality determination data 31 to detect the device 1. It may be the one that detects the abnormality of 1. This storage device information is the storage of the device information J1 of the device 1 acquired in the past by the processing unit 30. An example of the abnormality detection method in step S3 using this storage device information will be described.

For example, it is assumed that the average value of the past device information J1 accumulated as the storage device information by the processing unit 30 is "30 ° C", and the abnormality determination data 31 is "abnormal at 80 ° C or higher". Then, it is assumed that the newly acquired device information J1 is "50 ° C.". In this case, although the temperature "50 ° C." of the newly acquired device information J1 is lower than the "80 ° C." of the abnormality determination data 31, the processing unit 30 indicates the storage device information "30" indicating the state of the device 1 in the past. It is determined that the temperature has risen abnormally compared to "° C" and that "abnormality has occurred".
In this way, in the abnormality detection of the device 1, by using the stored device information in addition to the abnormality determination data 31, it is possible to detect the abnormality as compared with the normal operation. As a result, the accuracy of abnormality detection of the device 1 in the processing unit 30 can be improved.

In the above, after the abnormality of the device information J1 is detected in step S3, the device 1 in which the abnormality occurs in step S4 is specified from among the plurality of devices 1. However, the order of the processes is not limited, and steps S3 and S4 may be performed in the reverse order. In this case, it is assumed that the abnormality determination data 31 has a value set for each device 1. Then, the processing unit 30 identifies the device 1 corresponding to the acquired device information J1 based on the position information J3 added to the device information J1 (step S4). After that, it is determined whether or not an abnormality has occurred in the specified device 1 by using the value of the abnormality determination data 31 corresponding to the specified device 1 (step S3). In this case, the accuracy of abnormality detection in the processing unit 30 is improved.

Further, the processing unit 30 may constantly move the moving unit 20 within the TM branch office 10 for 24 hours to acquire the device information J1. Alternatively, the moving unit 20 may be moved at predetermined time intervals such as 5 o'clock, 10 o'clock, and 15 o'clock to acquire the device information J1. In the case where the moving unit 20 is made to acquire the device information J1 at each predetermined time interval, after it is determined that there is no abnormality in step S3 (steps S3, No), a predetermined time interval is set before returning to step S2. It is good to provide it.
When the processing unit 30 constantly moves the moving unit 20 to acquire the device information J1, there is an advantage that an abnormality in the device 1 can be quickly detected. Further, when the processing unit 30 moves the moving unit 20 at predetermined time intervals, the processing load on the processing unit 30 can be reduced.

The moving unit 20 acquires the device information J1 of the predetermined device 1 based on the device position information J4 added to the moving route information K while moving on the rail 7 according to the moving route information K (step S202).

As described above, in the present embodiment, the moving unit 20 acquires the device information J1 of the predetermined device 1 designated by the device position information J4. Therefore, the process of adding the position information J3 for identifying the device 1 to which the moving unit 20 has acquired the device information J1, which was performed in step S2 of the first embodiment, to the device information J1 is not performed.

Next, the processing unit 30 detects an abnormality in the predetermined device 1 based on the device information J1 of the predetermined device 1 acquired by using the device position information J4 and the abnormality determination data 31. That is, the processing unit 30 can identify the device 1 in which the abnormality has occurred from among the plurality of devices 1 by using the device position information J4 (step S203).
Next, the processing unit goes through the same steps as in steps S5 to S7 shown in FIG. 3 of the first embodiment to identify and show the device 1 in which the abnormality has occurred on the display unit 40, and the abnormality has occurred. Determine the abnormal type of device 1.

According to the maintenance device of the second embodiment configured as described above, the same effect as that of the first embodiment is obtained, and the device 1 in which the abnormality has occurred is identified from among the plurality of devices 1. As a result, maintenance work can be streamlined and equipment can be restored quickly.
Further, the moving unit 20 moves on the rail 7 according to the moving route information K designated by the processing unit 30, and only the device information J1 of the predetermined device 1 according to the device position information J4 added to the moving path information K. To get. As a result, the processing load in the processing unit 30 can be reduced.

Further, when only the device information J1 of the predetermined device 1 in the predetermined movement route information K is continuously acquired and stored as the storage device information, the storage device information is the predetermined device information J1 in the predetermined movement route information K. It is waveform data with the horizontal axis as the time axis, which shows the transition of the value of. In this case, in step S203, the storage device information (temperature waveform) in the predetermined movement path information K and the predetermined device information J1 in the newly acquired predetermined movement path information K during the normal operation of the TM branch office 10 ( The abnormality of the device 1 may be detected by comparing with the temperature waveform). In this way, the abnormality detection method of the device 1 in the processing unit 30 can be diversified to improve the detection accuracy.
Further, the storage device information (temperature waveform) in which the device information J1 of the predetermined device 1 in the predetermined movement path information K may be stored may be displayed on the display unit 40. In this case, the staff of the management center 50 can easily visually grasp the temperature state of the predetermined device 1 in the TM branch office 10 by a waveform graph or the like.
