The network N is, for example, a network such as the Internet, a dedicated line, or a LAN (Local Area Network). In the device management system 5, a wireless tag T is attached to each of a plurality of devices E installed in an area such as a room R, information is read from each wireless tag T by the reading device 2, and the read information is read by the device management device. It is transmitted to 1 and the information of each device E is managed by the device management device 1.

Each device E is a device to be managed, and includes various devices such as a PC (Personal Computer), a tablet computer, a smartphone, a feature phone, a router, and a switch. The device E is not limited to the electronic devices as described above, and may include various articles such as desks, chairs, and shelves. Each device E is, for example, a management target of fixed assets. In FIG. 1, each device E is installed in a room R in a building B.

Each wireless tag T records information (for example, device ID, device name, etc.) about the device E to which the wireless tag T is attached, and this information can be read by the reading device 2. For example, RFID (Radio Frequency Identification) can be used as a technique for reading information on a wireless tag. The radio tag T is, for example, an active RF (Radio Frequency) tag, and the information recorded on the radio tag T can be read by the reading device 2 at a position separated by 1 m or more.

Specifically, the layout information generation unit 113 superimposes the physical position information of each device E and the logical connection information of each device E in the designated building in steps S15 and S16. It is stored in the storage unit 12 in association with the ID and the room ID. The output control unit 114 generates an output screen including a layout diagram (update data) stored in the storage unit 12, transmits it to the user terminal 3 via the communication unit 13 and displays it.

Then, the device management device 1 ends the processing of the flowchart shown in FIG. As described above, the layout diagram in which the position information and the connection information of each device E installed in the designated room R are arranged is output. The position information of the reading device 2 may be arranged in the layout drawing.

FIG. 10 is a diagram showing an example of an output screen according to the embodiment. FIG. 10 shows an output screen 500 including a layout diagram displayed on the user terminal 3.

The output screen 500 displays the layout diagram 501. The layout diagram 501 includes a plan view 502 of the designated room R, an image 503 showing the position of each device E in the room R, and an image 504 showing the network connection information of each device E. In this figure, the network connection information is represented by a line connecting the images 503 of each device E. The output screen 500 displays the identifiers of the designated building B and room R (“building a” and “room b” in the figure).

The output screen 500 allows the user to easily confirm the physical position of the device. The user can easily find each device E when he / she visits the room R, for example, by printing the output screen 500 or displaying the output screen 500 on the portable user terminal 3.

In the above-described embodiment, the device management device 1 generates and outputs a layout drawing of a specific date and time. In one modification, the device management device 1 may generate and output a layout drawing of a date and time specified by the user.

Specifically, the device information receiving unit 111 stores the device information of each device acquired at different timings (for example, different dates) in the device information storage unit 122 in association with different acquisition dates and times 122f. That is, the device information of each device is managed by date and time. Further, the layout information acquisition unit 112 stores the layout information of each room R acquired at different timings (for example, different dates) in the layout information storage unit 123 in association with different creation date and time 123e. That is, the layout information of each room R is managed by date and time.

In the layout diagram output process, the output control unit 114 receives the designation of the date and time from the user terminal 3 in addition to the building ID and the room ID of the building B and the room R for which the layout diagram is created. Instead of accepting the date and time, a predetermined date and time (for example, the latest date and time) may be acquired. The layout information generation unit 113 reads out the layout diagram (original data) 123d included in the layout information associated with the designated or acquired date and time and the corresponding creation date and time 123e. Further, the layout information generation unit 113 uses the position information and connection of each device E by using the read layout diagram (original data) and the device information in which the designated or acquired date and time and the corresponding acquisition date and time 122f are associated with each other. Generate a layout diagram that reflects the information.

In this way, the user can easily confirm the physical position of each device in the room R at the designated date and time. Further, the user can confirm the correct layout diagram of the specified date and time even when the layout diagram (original data) of the room R is updated by remodeling the room R or the like.

The output control unit 114 may accept from the user terminal 3 the designation of two dates and times (the first date and time and the second date and time after that) that the user wants to compare with respect to the room R of the same building B. In this case, the layout information generation unit 113 associates the device information of each device E in which the first date and time received and the corresponding acquisition date and time 122f are associated with the second date and time received and the corresponding acquisition date and time 122f. The difference is specified by comparing with the device information of each device E. For example, if the device information is added on the second date and time, the layout information generation unit 113 can specify the device E added in the room R. Further, for example, if the device information is deleted on the second date and time, the layout information generation unit 113 can identify the deleted (removed) device E from the room R. Further, for example, if the position 122d or the detailed data 122e of the device information of the same device E is changed, the layout information generation unit 113 can specify the device E whose position or connection relationship has been changed in the room R.

Further, the layout information generation unit 113 reads out the layout diagram (original data) 123d included in the layout information associated with the creation date and time 123e corresponding to the second date and time. Then, the layout information generation unit 113 generates a layout diagram that reflects the position information and connection information of each device E by using the read layout diagram (original data) and the device information of the second date and time. At this time, the layout information generation unit 113 reflects the information indicating the difference between the position information and the connection information of each device E on the second date and time by using the device information on the first date and time. The output control unit 114 displays the position information and the connection information of the added device E in a manner different from that of the other devices E. Further, the output control unit 114 displays the position information and the connection information of the deleted (removed) device E in a mode different from that of the other devices E. Further, the output control unit 114 displays the position information and the connection information before and after the change in the device E whose position has been changed in a mode different from that of the other devices E. Further, the output control unit 114 displays the connection information before and after the change in the device E whose connection relationship has been changed in a mode different from that of the other devices E.
