Equipment information management system and equipment information management method

The present invention relates to an equipment information management system and an equipment information management method.

In recent years, technologies for using robots to specify the position of the robot and to obtain information about the robot's surroundings have been studied. For example, by installing a number of two-dimensional codes with current location information embedded in them indoors, and reading the two-dimensional codes and other information using a camera mounted on a self-propelled robot, the robot's current location can be determined. In addition, a device that adds information about the location of the photograph to a photograph taken indoors is conceivable.

Here, Patent Document 1 discloses a position estimation device. The summary of the position estimating device in Patent Document 1 states, ``A code that can identify the position is installed on the equipment floor, and the position estimating device 1 takes images of the surrounding area and calculates the distance to surrounding objects. The self-position is estimated by measuring and obtaining scan data, detecting the code from the image, and matching the scan data and map data based on the position of the detected code. ``can reduce misperceptions.''

The information extraction unit 24 detects the moving object detection unit 1 from the appearance information and identifies the rack 10. Furthermore, the information extraction unit 24 can extract the second identifier indicated by the two-dimensional code displayed on the information display unit 13 from the appearance information. Further, the information extraction unit 24 can also identify the model of the device 11 and the mounting position of the rack in which the device 11 is mounted from the appearance information.

The map creation unit 25 creates two-dimensional map data based on data acquired from the surrounding environment scanning unit 31 and the inertial measurement unit 32.

The information integration unit 23 identifies the position of the rack 10 on the two-dimensional map and associates it with the first identifier. The information integration unit 23 can also manage the position of the device 11 by linking the second identifier to the same location as the mounting position of the moving object detection unit 1 on the two-dimensional map. Furthermore, if the power state of the restarted device 11 and the power lamp state of the video captured by the information acquisition device 20 match, the information integration unit 23 adds a second identifier to the two-dimensional map. , the location of the device 11 may be managed by linking the first identifier to the same location as the mounting location of the moving object detection unit 1. Further, the information integration unit 23 may transmit a two-dimensional map in which the second identifier is linked to the same location as the mounting position of the moving object detection unit 1 to the machine room management unit 50.

The machine room management section 50 is composed of a server. The servers that make up the machine room management unit 50 include a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), HDD (Hard Disk Drive), input/output I/F (Interface), and communication. An I/F and a media I/F are provided. The machine room management unit 50 aggregates information about the machine room 100 and automatically installs new racks 10, updates databases when devices 11 are installed, and arranges for troubleshooting.

When the machine room management unit 50 receives the unknown first identifier, it instructs the information acquisition device 20, which is a moving object, to search for the newly installed rack and moves it, and distinguishes between a moving object detection signal and an undetected signal. The position of the rack 10 is estimated based on the range in which the detection signal is received and the information on the inaccessible place. The machine room management unit 50 also instructs the information acquisition device 20 to take a video of external appearance information in a direction from which entry is not possible from the center where the detection signal was received, and restarts the device 11 with the second identifier. let Note that the machine room management unit 50 is not limited to the instruction to shoot a video, but may also be an instruction to record the video.

The worker WK is a worker who works on-site based on a work request (arrangement) from the machine room management department 50.

<First embodiment>
In the first embodiment of the present invention, the worker WK newly installs a rack in the machine room 100, and the equipment information management system manages the rack position.

FIGS. 2A to 2C are flowcharts showing the process by which the equipment information management system manages the standing position of the rack.

First, worker WK installs a new rack 10 and erects it (step S1). Further, the worker WK installs the moving object detection section 1 and the detection information control section 2 on the rack 10 (step S2). Then, the worker WK connects the detection information control section 2 to the machine room management section 50 (step S3). When the worker WK connects the detection information control section 2 to the machine room management section 50, the detection information control section 2 can communicate with the machine room management section 50.

The detection information control section 2 sets the identifier "A" (first identifier) of the moving object detection section 1 and transmits it to the machine room management section 50 at the timing when there is no one left after the work of the worker WK is completed. . The identifier of the moving object detection section 1 can be, for example, a serial number set at the time of manufacturing the moving object detection section 1, and the detection information control section 2 uses the undetected signal and the identifier "A" of the moving object detection section 1. , to the machine room management section 50.

The machine room management section 50 waits to receive a not found signal from the detection information control section 2 (No in step S4), and upon receiving the not found signal (Yes in step S4). , it is determined whether the identifier "A" of the moving object detection section 1 is a signal from the moving object detection section 1 whose identifier has not yet been mapped on the two-dimensional map held by the machine room management section 50 (step S5). Note that the machine room management unit 50 has previously acquired a two-dimensional map created by the map creation unit 25 of the information acquisition device 20.

If the identifier “A” of the moving body detection unit 1 is a signal from the moving body detection unit 1 whose identifier is not mapped on the two-dimensional map of the machine room management unit 50 (Yes in step S5), the machine room management unit 50: It is determined that the rack is standing, and the information acquisition device 20 is instructed to search for the rack 10 (step S6).

On the other hand, if the identifier "A" of the moving object detection section 1 is a signal from the moving object detection section 1 whose identifier is mapped on the two-dimensional map (No in step S5), the process returns to step S4 and the undetected signal is not received. Waiting.

FIG. 3 is an explanatory diagram showing a process in which the machine room management section determines that the rack is standing and instructs the information acquisition device to search for the rack. As shown in FIG. 3, upon receiving the undetected signal from the detection information control unit 2, the machine room management unit 50 instructs the information acquisition device 20 to search for the rack 10.

Returning to FIG. 2A, the explanation continues. The information acquisition device 20 moves randomly on the two-dimensional map of the machine room 100 (step S7).

The information acquisition device 20 generates and updates a two-dimensional map based on the information collected by the surrounding environment scanning unit 31 and the inertial measurement unit 32 (step S8 in FIG. 2B).

The machine room management unit 50 waits to receive the detection signal of the target identifier “A” from the detection information control unit 2 (No in step S9), and upon receiving the detection signal of the identifier “A” ( (Yes in step S9), the information acquisition device 20 is instructed to perform rack position specifying processing (step S10).

FIG. 4 is an explanatory diagram illustrating a situation in which the machine room management department discovers the position of a newly installed rack in the information acquisition device.

As shown in FIG. 4, the machine room 100 is provided with existing racks 200 to 206 and a new rack 300. A moving object detection section 1 and a detection information control section 2 are installed in the newly installed rack 300. In FIG. 4, the moving object detection unit 1 detects the information acquisition device 20, and the detection information control unit 2 assigns an identifier “A” and outputs a detection signal, so that the machine room management unit 50 detects the information acquisition device 20. Instructs the rack position specifying process.

Note that the moving object detection unit 1 is adjusted to detect only an area that is the same as the width of the newly installed rack 300 and a range of 40 [cm] in front of the newly installed rack 300, for example.

Returning to FIG. 2B, the explanation continues. The information acquisition device 20 moves randomly around its own device and determines the position of the information acquisition device 20 at the moment when it receives the detection signal or the undetected signal from the detection information control unit 2, together with the detected signal or the undetected signal. Mapping is performed on a two-dimensional map (step S11). In addition, in the drawings, the meaning of "or" may be expressed as "/".

FIG. 5 is an explanatory diagram illustrating a situation in which the machine room management section instructs the information acquisition device to perform rack position identification processing.

As shown in FIG. 5, in the machine room 100, the information acquisition device 20 moves randomly until the position of the newly installed rack 300 is estimated. When the machine room management unit 50 receives the undetected signal from the detection information control unit 2, it causes the information acquisition device 20 to return to the range where the detection signal was received, and then moves randomly again.

The detection information control unit 2 transmits a detection signal to the machine room management unit 50 if the information acquisition device 20 is within the detection range (within the width of the newly installed rack 300), and if the information acquisition device 20 moves outside the detection range. , transmits an undetected signal to the machine room management section 50. In step S11, the machine room management unit 50 maps the position of the information acquisition device 20 at the moment of receiving the detected signal or the undetected signal on a two-dimensional map together with the detected signal and the undetected signal, thereby detecting the detected signal. The receiving range is estimated to be the position of the newly installed rack 300.

Returning to FIG. 2B, the explanation continues. The machine room management unit 50 determines whether or not the location of the newly installed rack 300 can be estimated by finding a location within the reachable range of the detection signal and which is inaccessible (step S12). Here, a place that cannot be entered is, for example, a place that can be moved randomly on the two-dimensional map, but it is a place that cannot be entered due to the two-dimensional map being updated by the surrounding environment scanning unit 31 and the inertial measurement unit 32. It refers to a place where it is no longer possible to do something.

FIG. 6 is a conceptual diagram in which the machine room management department maps the position of the information acquisition device, detected signals, and undetected signals on a two-dimensional map.

As shown in FIG. 6, the machine room management unit 50 creates a detected signal range area AR1 and an undetected signal range area AR2, and estimates the location of the newly installed rack 300 to be a place that cannot be entered within the range where the detected signal can reach. do.

Returning to FIG. 2B, the explanation continues. In step S12, if the machine room management unit 50 determines that the position of the newly installed rack 300 has been estimated (Yes in step S12), the information acquisition device 20 is moved to the center of the detection signal range area AR1, and the position of the newly installed rack 300 is estimated. It is made to face the estimated position (step S13).

On the other hand, if it is determined that the position of the newly installed rack 300 cannot be estimated (No in step S12), the machine room management section 50 determines whether an undetected signal has been received from the detection information control section 2 (step S14), If an undetected signal is received (Yes in step S14), the information acquisition device 20 is moved to the range where the detected signal was present (step S15), and the process returns to step S11. On the other hand, if the undetected signal has not been received (No in step S14), the machine room management section 50 returns to step S11.

In step S13, when the machine room management unit 50 causes the information acquisition device 20 to face the estimated position of the newly installed rack 300, the information acquisition device 20 acquires appearance information of the newly installed rack 300 using the external information acquisition unit 30 ( Step S16 in FIG. 2C).

FIG. 7 is an explanatory diagram showing a situation in which the information acquisition device acquires external appearance information of a newly installed rack. As shown in FIG. 7, the information acquisition device 20 acquires appearance information of the newly installed rack 300.

Returning to FIG. 2C, the explanation continues. The information acquisition device 20 analyzes the acquired information and detects the moving object detection unit 1 (step S17). The information acquisition device 20 previously holds the appearance information of the moving object detection unit 1 as data, and refers to it when the information acquisition device 20 analyzes the appearance information to identify the moving object detection unit 1. In this case, the information acquisition device 20 analyzes the appearance information using the information extraction unit 24, and when the moving object detection unit 1 is detected, the newly installed rack 300 is determined.

The information acquisition device 20 maps the position of the newly installed rack 300 on the two-dimensional map (step S18), and transmits the map information of the created two-dimensional map to the machine room management unit 50 (step S19).

The machine room management unit 50 instructs the detection information control unit 2 to change the signal emission policy (step S20), and ends the processing from FIG. 2A to FIG. 2C.

Here, changing the signal emission policy means that in the process described above, all the detection signals of the moving object detection unit 1 were sent to the machine room management unit 50, but the position of the newly installed rack 300 is determined. As a result, from now on, for example, it will be changed to transmit only when the detection signal continues for 15 seconds or more. This makes it possible to invalidate the case where a person simply passes in front of the rack 10, and it is possible to determine only the case where some work has been done on the rack 10.

<Second embodiment>
In the second embodiment of the present embodiment, the equipment information management system detects that the worker WK is working in front of a rack 10, moves the information acquisition device 20 to the rack 10, and acquires information on the device 11. .

FIGS. 8A and 8B are flowcharts showing a process in which the equipment information management system detects the work of a worker in front of a rack and acquires rack information. Note that in the second embodiment, the device 11 mounted on the rack 10 includes an information display section 13. Further, in the second embodiment, it is assumed that the position of the rack 10 has been specified in the first embodiment.

First, in the second embodiment, after the position of the rack 10 is determined according to the first embodiment, the vendor delivers the device 11 and the worker WK who carries out the work of loading it on the rack 10 enters the machine room 100. (Step S100).

The worker WK mounts the device 11 in the empty space of the rack 10 and connects the cable so that it can communicate with the machine room management section 50 (step S101). The worker WK turns on the device 11 and confirms that the two-dimensional code is displayed on the information display section 13 (step S102).

The detection information control unit 2 determines whether or not a not found signal is received after the detection (found) signal from the moving object detection unit 1 to the detection information control unit 2 continues for 15 seconds or more ( Step S103).

That is, the detection information control unit 2 waits to receive an undetected signal after the detection signal continues for 15 seconds or more (No in step S103), and waits to receive the undetected signal after the detection signal continues for 15 seconds or more. If so (Yes in step S103), the undetected signal is transferred to the machine room management section 50 (step S104).

The machine room management unit 50 waits to receive an undetected signal from the detection information control unit 2 (No in step S105), and when the undetected signal is received from the detection information control unit 2 (Yes in step S105), the machine room management unit 50 detects a moving object. Upon receiving the notification (identifier "A") from the detection unit 1, the information acquisition device 20 is caused to start moving to the position of the moving object detection unit 1 (step S106).

FIG. 9 is an explanatory diagram showing that the machine room management section receives the undetected signal and issues an information acquisition instruction to the information acquisition device.

As shown in FIG. 9, the detection information control section 2 assigns the identifier "A" of the moving object detection section 1 to the detection signal or the undetected signal. If the detection information control unit 2 does not immediately transfer the signal with the identifier "A" and receives an undetected signal after the detection signal continues for 15 seconds or more, it determines that work has occurred on the rack 10. Then, the undetected signal is transferred to the machine room management section 50. Here, when the detection information control unit 2 receives an undetected signal after the detection signal continues for 15 seconds or more, the operator WK simply passes in front of the moving object detection unit 1 by transmitting the undetected signal. cases can be excluded.

The machine room management unit 50 holds a two-dimensional map of the machine room 101 and the position of the target rack 10. Therefore, upon receiving the undetected signal, the machine room management unit 50 outputs an information acquisition instruction to the information acquisition device 20. Since the information acquisition device 20 has the two-dimensional map in the control unit 22 in advance, it moves to the target rack 10.

Returning to FIG. 8B, the explanation continues. The information acquisition device 20 arrives in front of the moving object detection unit 1 that received the notification (step S107). The information acquisition device 20 uses the external information acquisition unit 30 to photograph the external appearance of the rack 10 (step S108).

FIG. 10 is an explanatory diagram showing a situation where the external information acquisition unit of the information acquisition device is photographing the external appearance of the target rack in the machine room.

As shown in FIG. 10, the information acquisition device 20 moves to the front of the target rack 301 with the identifier "A" based on the information on the two-dimensional map.

Returning to FIG. 8B, the explanation continues. The information extraction unit 24 of the information acquisition device 20 identifies the model and the number of units of the device (indicated as "number U" in each figure) by image analysis (step S109). The surrounding environment scanning unit 31 of the information acquisition device 20 measures the vertical width of the rack mounting space in the target rack 301 and calculates the total number of units based on the EIA (Electric Industries Alliance) standard (step S110).

The surrounding environment scanning unit 31 calculates and specifies in which unit each device is located based on the distance from the bottom of the target rack 301 (step S111). The information extraction unit 24 of the information acquisition device 20 reads the two-dimensional code displayed on the information display unit 13 of the target rack 301, and acquires an identifier (second identifier) included in the two-dimensional code (step S112).

The information integration unit 23 maps the acquired equipment identifier to the same location as the moving object detection unit 1 on the two-dimensional map (step S113).

FIG. 11 is an explanatory diagram showing a process in which the information acquisition device acquires external appearance information, extracts the mounting position of the target rack and the device identifier, and maps them onto a two-dimensional map.

As shown in FIG. 11, the external information acquisition unit 30 of the information acquisition device 20 acquires external appearance information of the racks 10 that constitute the target rack 301, and the information extraction unit 24 performs image analysis to Identify the model. Further, the information extracting unit 24 measures the vertical width of the rack mounting space, grasps the entire unit, and specifies in which unit the devices 60 and 61 are located from the bottom of the target rack 301.

The vertical width of the rack 10 is defined as, for example, 44.45 [mm] as one unit, and by repeating the size of this one unit, the entire unit and the mounting position can be specified. Further, a two-dimensional code is displayed on the information display section 13 of the devices 60, 61, and the information extraction section 24 extracts the identifier (second identifier) of the device 60, 61 from the two-dimensional code. . Note that the information acquisition device 20 holds external appearance information of the devices 60 and 61 installed in advance as data, and the information extraction unit 24 can identify the model of the device by analyzing the image.

FIG. 12A is an explanatory diagram showing that a two-dimensional code is displayed on the information display section of the device. For example, a two-dimensional code 62a is displayed on the information display section 62 of the device 60. The information display section 62 is provided on the front side of the device 60, and a two-dimensional code 62a is displayed on a part of the information display section 62. The same applies to the information display section 13 below.

FIG. 12B is an explanatory diagram showing that the device identifier is extracted from the two-dimensional code on the information display section of the device, and the distance from the bottom of the target rack is specified. For example, the information extraction unit 24 of the information acquisition device 20 extracts the identifier “P” of the device 60 from the two-dimensional code 62a of the information display unit 62 of the device 60, and also identifies the model of the device 60 as “XXXXX” from the external appearance information. Specify. Furthermore, the types of devices 60 are mounted in 24 units from the bottom of the rack 10.

Similarly, the information extraction section 24 extracts the identifier "Q" of the device 61 from the two-dimensional code on the information display section of the device 61, for example, and specifies the model of the device 61 as "YYYYY" from the appearance information. Further, the models of the devices 61 are installed in 20 units from the bottom of the rack 10.

Returning to FIG. 8B, the explanation continues. When the information acquisition device 20 transmits the created map information to the machine room management section 50 (step S114), the processing in FIGS. 8A and 8B ends.

<Third embodiment>
In the third embodiment of the present embodiment, similarly to the second embodiment, the equipment information management system detects that the worker WK is working in front of the rack 10 and moves the information acquisition device 20 to the rack 10. , obtain information on the device 11. Note that in the third embodiment, it is assumed that the device 11 does not include the information display section 13.

The processing of the third embodiment differs from the second embodiment in the processing after step S112 in FIG. 8B in FIGS. 8A and 8B. Therefore, in the third embodiment, FIG. 13A shows that the same process up to step S111 in FIG. 8B is executed, and FIG. 13B shows that the process from step S200 onwards, which is the process of the third embodiment, is executed. .

In step S200 shown in FIG. 13B, the machine room management unit 50 determines whether there is an identifier of the device 11 that has newly started communication, and if there is an identifier of the device 11 that has newly started communication, (step S200 (Yes), the information acquisition device 20 is instructed to record (shoot a video) the device in front of the target rack 301 (step S201).

On the other hand, if there is no identifier for the device 11 that has newly started communication (No in step S200), the machine room management unit 50 waits until there is an identifier for the device 11 that has newly started communication.

The information acquisition device 20 starts recording the situation in front of the target rack 301 (step S202), and the machine room management unit 50 instructs the device that is newly able to communicate to restart (step S203). ).

When the device 11 is restarted, the power lamp changes from ON to OFF to ON (step S204). The information acquisition device 20 uses the information extraction unit 24 to analyze the video, determine in which unit and which model of device the power lamp changes, and record the time at which the change occurred (step S205).

The machine room management unit 50 records the time when rebooting was instructed, the time when communication with the target device was interrupted, and the time when communication was resumed due to rebooting, for each state of the power lamp recorded by the information extraction unit 24 of the information acquisition device 20. (Step S206 in FIG. 13C).

The information extraction unit 24 of the information acquisition device 20 determines whether the power lamp and the timing of communication ON→OFF→ON match within an error of one minute or not (step S207). If the power lamp and the communication timing match (Yes in step S207), the information extraction unit 24 performs the matching again by restarting the recording and the device, and determines whether they match within the same error (step S207: Yes). S208).

If the power lamp and communication timing match within the same error (Yes in step S208), the information integration unit 23 stores the newly acquired identifier (second identifier) (step S209).

On the other hand, in step S207 or step S208, if the power lamp and the communication timing do not match within the same error, the information extraction unit 24 returns to step S206 and repeats the comparison.

When the information acquisition device 20 transmits the created map information to the machine room management unit 50 (step S210), it ends the processing from FIG. 13A to FIG. 13C.

FIG. 14 is an explanatory diagram showing a process in which the information acquisition device acquires external appearance information, extracts the mounting position of the target rack and the device identifier, and maps them onto a two-dimensional map in the third embodiment.

The information acquisition device 20 continues to take images of the rack 10, and identifies the device to be viewed as the device 70 based on the model information set with the identifier “R”.

When the device 70 with the identifier "R" is restarted, the power lamp changes from OFF to ON. The machine room management unit 50 instructs the restart and compares the timing when the notification from the identifier "R" is stopped and the timing when the power is turned on from OFF, and if the times match with an error of ±1 minute, , this device determines that the identifier is "R". Furthermore, by repeating the restart twice at a predetermined timing, the machine room management unit 50 can eliminate coincidences, determine that the device with the identifier "R" is the device 70, and map the two-dimensional map. can be written to.

FIG. 16 is an explanatory diagram showing that the identifier "R" of the device 70 has been identified for the model name "ZZZZZZ" in the image analysis information 242 of FIG. 15. The machine room management unit 50 can identify the identifier "R" as "ZZZZZZZ" of the device 70 by restarting the power supply of the identifier "R". The information integration unit 23 can map the information of the device 70 as the image analysis information 243 of the target rack 301 by linking it to the identifier “A” (first identifier) of the moving object detection unit 1.

<Fourth embodiment>
In the fourth embodiment, in addition to the second embodiment or the third embodiment, the machine room management section 50 realizes failure handling.
