Description

[Technical Field]

[0001] The present disclosure relates to a remote operation support method, a remote management device, a remote operation support system, and a remote operation support program. [Background technology]

[0002] Systems that restrict the remote operation of appliances have been known for some time. For example, the system disclosed in Patent Document 1 selects operable functions from among a plurality of functions possessed by the appliance depending on whether the operating device is located outside the home (outside the customer facility). The operating device can ensure safety by setting only those functions of the appliance that have a low risk of causing, for example, an electric leakage accident or a fire as remotely operable. Since the operating device cannot transmit operating instructions for functions that cannot be operated, the input of unnecessary information and transmission of operating instructions are prevented.

[0009] Hereinafter, embodiments will be described with reference to the drawings. Embodiment FIG. 1 shows a configuration of a remote operation support system according to an embodiment.

[0010] The remote operation support system includes a local device 1, a local management device 2 that manages and controls the local device 1, a remote management device 3, and a network 4. The local device 1 is, for example, an air conditioning device or an elevator installed in a building. The local management device 2 directly controls or manages the local device 1. The remote management device 3 controls or manages the local device 1 through the local management device 2 in accordance with a remote operation screen. The local management device 2 and the remote management device 3 are configured to be able to communicate with each other via the network 4.

[0011] 2 is a diagram showing the configuration of the on-site management device 2. The on-site management device 2 includes a memory 21, a processor 22, and a communication circuit .

[0012] The memory 21 stores a local management program. The communication circuit 23 communicates with the remote management device 3 via the network 4.

[0013] The processor 22 executes the on-site management program stored in the memory 21. For example, upon receiving a request from the remote management device 3 via the communication circuit 23 to transmit a signal representing a remote operation screen for remotely operating on-site devices, the processor 22 transmits the signal representing the remote operation screen to the remote management device 3 via the communication circuit 23.

[0014] 3 is a diagram showing the configuration of the remote management device 3. The remote management device 3 includes a memory 31, a processor 32, a communication circuit 33, an input device , and a display device .

[0015] The memory 31 stores a remote management program. The input device 34 receives input from a user (monitor) of the remote management device 3. The display device 35 displays a remote operation screen for remotely operating the local device 1. The communication circuit 33 communicates with the local management device 2 via the network 4.

[0016] The processor 32 stores the remote management program stored in the memory 31. For example, the processor 32 requests the on-site management device 2 to transmit a signal representing a remote operation screen for remotely operating the on-site device via the communication circuit 33. The processor 32 receives the signal representing the remote operation screen for remotely operating the on-site device via the communication circuit 33, and modifies the remote operation screen by modifying, among the tags included in the received signal, tags having a specified tag name and a specified attribute value to be inactive or hidden, and displays the modified remote operation screen on the display device 35.

[0017] FIG. 4 is a flowchart showing the procedure of the remote operation support method by the remote operation support system according to the embodiment.

[0018] In step S101, the processor 32 of the remote management device 3 starts up a Web (World Wide Web) browser in response to a request from the user of the remote management device 3 via the input device .

[0019] In step S102, the processor 32 of the remote management device 3 accepts an input of the URL (Uniform Resource Locator) of the Web server of the local management device 2 by the user of the remote management device 3 via the input device .

[0020] In step S103, the processor 32 of the remote management device 3 creates an HTTP (Hypertext Transfer Protocol) request based on the URL.

[0021] In step S104, the processor 32 of the remote management device 3 transmits an HTTP request through the communication circuit 33.

[0022] In step S104, the processor 22 of the on-site management device 2 receives the HTTP request through the communication circuit .

[0023] In step S105, the processor 22 of the on-site management device 2 creates an HTTP response.

[0024] In step S106, the processor 22 of the on-site management device 2 transmits an HTTP response through the communication circuit 23.

[0025] In step S107, the processor 32 of the remote management device 3 receives the HTTP response through the communication circuit 33.

[0026] In step S109, if the HTML (Hyper Text Markup Language) file included in the HTTP response contains a tag specified in the Disable table, the process proceeds to step S110.

[0027] In step S110, if the attribute value of the tag specified in the Disable table in the HTML file matches the attribute value specified in the Disable table, the process proceeds to step S111.

[0028] In step S111, the processor 32 of the remote management device 3 modifies the HTML file by setting the specified tag in the HTML file to Disable (inactive), and stores the modified HTML file in the memory 31.

[0029] In step S112, if the tag specified in the Hidden table is present in the HTML (Hyper Text Markup Language) file included in the HTTP response, the process proceeds to step S113.

[0030] In step S113, if the attribute value of the tag specified in the Hidden table in the HTML file matches the attribute value specified in the Hidden table, the process proceeds to step S114.

[0031] In step S114, the processor 32 of the remote management device 3 modifies the HTML file by setting the specified tag in the HTML file to Hidden, and stores the modified HTML file in the memory 31.

[0032] In step S115, the processor 32 of the remote management device 3 displays on the display device 35 the contents of the HTML file modified by the Web browser.

[0033] Fig. 5 is a diagram showing an example of an HTML file received by the remote management device 3. Fig. 6 is a diagram showing a screen displayed in accordance with the HTML file of Fig. 5.

[0034] The HTML file contains the input tag shown in Figure 5 (1). The value of the type attribute of this input tag, which indicates the shape of the component, is "submit", the value of the name attribute, which indicates the name of the component, is "initialize", and the value attribute, which indicates the initial value of the component, is "initialization". Based on this input tag, a text box with "initialization" written as the initial value is displayed, as shown in Figure 6 (A).

[0035] The HTML file contains the input tag shown in Figure 5 (2). The value of the type attribute of this input tag, which represents the shape of the component, is "submit", the value of the name attribute, which represents the name of the component, is "opentest", and the value of the value attribute, which represents the component's initial value, is "open test". Based on this input tag, a text box with "open test" written as the initial value is displayed, as shown in Figure 6 (B).

[0036] Figure 7 shows an example of a Disable table. The Disable table specifies tags to be set to Disable by their tag names and the values ​​of one or more attributes. The Disable table in Figure 7 specifies that, among input tags, tags whose type attribute value is "submit", whose name attribute value is "initialize", and whose value attribute value is "initial setting" are to be set to Disable.

[0037] Figure 8 shows an example of a Hidden table. The Hidden table specifies tags to be set to Hidden by their tag names and one or more attribute values. The Disable table in Figure 7 specifies that input tags with a type attribute value of "submit", a name attribute value of "opentest", and a value attribute value of "Open Test" are to be set to Hidden.

[0038] Fig. 9 is a diagram showing an example of an HTML file after correction by the remote management device 3. Fig. 10 is a diagram showing a screen displayed in accordance with the HTML file after correction of Fig. 9.

[0039] The corrected HTML file contains the input tag shown in Figure 9 (1). "Input" matches the tag name specified in the Disable table in Figure 7. The value of this input tag's type attribute is "submit", the value of its name attribute is "initialize", and the value of its value attribute is "initialization", which match the attribute values ​​specified in the Disable table in Figure 7. Therefore, this input tag is set to Disable. As a result, a text box that cannot be entered (is inactive) and has "initialization" as its initial value is displayed, as shown in Figure 10 (A).

[0040] The corrected HTML file contains the input tag shown in Figure 9 (2). "input" matches the tag name specified in the Hidden table in Figure 8. The value of the type attribute of this input tag is "submit", the value of the name attribute is "opentest", and the value of the value attribute is "open test", which match the attribute values ​​specified in the Hidden table in Figure 8. Therefore, this input tag is set to Hidden. As a result, the text box with the initial value "open test" is not displayed, as shown in Figure 10 (B).

[0041] As described above, according to this embodiment, remote operation of a device can be restricted in a simple manner. In this embodiment, remote operation of setting values ​​and control of the device can be prevented, thereby ensuring security and safety. Remote operation can be restricted without modifying the Web server of the on-site management device for remote operation. Setting values ​​can be changed and devices can be controlled remotely without restriction from devices other than the remote management device, such as the on-site management device.
