Since common items are displayed between the devices selected in this way, it is easy to compare the display results.

[Comparative example]
Next, effects of the present embodiment will be described while comparing with modes assumed in the prior art. FIG. 5 is a diagram illustrating an example of a screen display according to a comparative example of the present embodiment. As shown in FIG. 5, in the comparative example, items to be selected for each device are displayed for the ten devices 01 to 10. When displaying information on a plurality of devices, it is easier for the user to compare the display results if a common item is selected for each device. In FIG. 5, when a common item is selected among the selected display target devices, the operation amount of the user increases in proportion to the number of devices. As a first example, when the item 01 is selected for the devices 01 to 10, the user checks 10 locations. As a second example, when selecting item 01 and item 02 for device 01 to device 10, the user must check 20 locations. Furthermore, as a third example, when selecting item 01 to item 03 for device 01 to device 10, the user must check 30 locations. Further, it is difficult to fit the display of FIG. 5 within one screen in the limited display space of the terminal device 50. For this reason, it is necessary to display the screen over a plurality of pages or to reduce the identifier, and the visibility is lowered.

  On the other hand, in the present embodiment, a device selection screen 21 for selecting a device and an item selection screen 22 for selecting an item are separately provided so that only common items can be selected for each selected device. It is configured (see FIG. 2). Thereby, compared with the comparative example (FIG. 5), a user's operation amount is reduced. In addition, since it is not necessary to perform display for selecting an item for each device, the display space of the selection screen can be reduced as compared with the comparative example (FIG. 5). Thereby, a plurality of items related to a plurality of devices can be selected in a limited display space. Moreover, since the data display screen 23 which shows a selection result with the apparatus selection screen 21 and the item selection screen 22 can be displayed in the predetermined screen 20, visibility is high compared with a comparative example (FIG. 5).

(Second Embodiment)
Next, a second embodiment will be described. Below, the description of the structure common to 1st Embodiment is abbreviate | omitted, and only a different structure is demonstrated.
The device information display system 100A of the present embodiment is a remote monitoring system that monitors a monitoring target device 30 (corresponding to “a plurality of devices” of the present invention) with a management server.

  Next, the terminal device 50B displays the item selection screen 22 on the maintenance monitor screen 20 (see FIG. 11), and the user selects an item (step S104). In FIG. 11, the user has selected identification numbers 3Δ, 3 × (incoming water temperature, outgoing hot water temperature) corresponding to two items from among 100 items.

  Next, the terminal device 50B acquires data (step S105). In the system selection screen 24 displayed on the maintenance monitor screen 20 (see FIG. 11), when the user inputs a 4-digit authentication number (optional but for example 0000) in the authentication number input box and selects the start button, the terminal A list of selected devices and items is transmitted from the Web browser of the device 50B to the management server 40, and an acquisition request (list of devices and items) is transmitted from the management server 40 to the terminal device 50B. The terminal device 50B acquires the monitor information of the items included in the acquisition request received from the management server 40 from each device of the monitoring target device 30, and when the acquisition of the monitor information of all items is completed, the terminal device 50B returns an acquisition response (device and List of items and acquired data).

  Next, the terminal device 50B displays the acquired data (step S106). In the system selection screen 24 displayed on the maintenance monitor screen 20 (see FIG. 11), after the user selects the start button, the Web browser of the terminal device 50B inquires the server about the acquisition result at intervals of 1 second. Then, the terminal device 50B displays the acquisition result on the data display screen 23 of the maintenance monitor screen 20. On the data display screen 23, two items (identification numbers) 3Δ, selected on the item selection screen 22 for the syscon SC1, the hot water heater WH1, and the hot water heater WH2 that are display target devices selected on the device selection screen 21. Data relating to 3 × (incoming water temperature, outgoing temperature) is displayed. In FIG. 11, the data for item 3Δ (incoming water temperature) of hot water heater WH1 is 26.5 ° C., and the data for item 3 × (hot water temperature) of hot water heater WH1 is 27.5 ° C. The data for item 3Δ (incoming water temperature) of hot water heater WH2 is 27.0 ° C., and the data for item 3 × (outlet temperature) of hot water heater WH2 is 27.0 ° C. Here, since the two items (identification numbers) 3Δ and 3 × are items meaningful only for the water heater, the system controller SC1 does not display the corresponding data.

  Finally, the terminal device 50B stops data acquisition (step S107). As soon as the server 40 receives the acquisition response from the terminal device 50B, the server 40 repeats the process of transmitting the same acquisition request as the previous time. As a result, the latest acquisition result updated sequentially is displayed on the data display screen 23. Here, in the system selection screen 24 displayed on the maintenance monitor screen 20 (see FIG. 11), when the user selects the stop button or 30 minutes have elapsed from the start of data acquisition, the operation stops.

  According to the present embodiment, the item selection screen is also used in the remote monitoring system 100B of the type in which the management server 40 monitors the plurality of water heaters WH1 to WH24 and the system controllers SC1 to SC3 that control the number of these water heaters. Since it is not necessary to provide for each type of device, it is possible to suitably realize the selection display of the monitoring target device 30 and its items.

  In this embodiment, the system controller, which is the second type of equipment, is configured to control the number of water heaters operated by a plurality of SC1 to SC3, but is controlled by a single system controller. Also good. For details of the operation number control function by a single system controller, see, for example, Japanese Patent Publication No. 8-30607.
