Description

Technical Field

[0001] This disclosure relates to remote operation support methods, remote management devices, remote operation support systems, and computer program products. Background Technology

[0002] Previously, systems with restrictions on remote operation of equipment were known. For example, the system in International Publication No. 2015 / 115572 selects operable functions from multiple functions of the equipment based on whether the operating device is located outdoors (outside the user's facility). The operating device only sets functions with low risk of causing electrical leakage or fire to be remotely operable, thereby ensuring safety. The operating device cannot send operation instructions for inoperable functions, thus preventing the input of useless information and the transmission of operation instructions. Summary of the Invention

[0003] In the system described in Patent Document 1, some functions are designed to be non-remotely operable, thereby ensuring security. However, in the system described in Patent Document 1, the process becomes complicated due to the need for detection of whether the operating device is located outdoors (outside the user's facility).

[0004] Therefore, the purpose of this disclosure is to provide a remote operation support method, remote management device, remote operation support system, and computer program product that can restrict remote operation of a device in a simple way.

[0005] The remote operation support method disclosed herein includes the following steps: a remote management device receives a signal representing a remote operation screen for remote operation of a local device; the remote management device modifies the remote operation screen by deactivating or disabling a label in the received signal that has a specified label name and a specified attribute value; and the remote management device displays the modified remote operation screen.

[0006] The above and other objects, features, aspects and advantages of the present invention will become clear from the following detailed description of the invention, which is understood in conjunction with the accompanying drawings. Attached Figure Description

[0017] The embodiments will now be described with reference to the accompanying drawings.

[0018] Implementation method.

[0019] Figure 1 This is a diagram showing the structure of the remote operation support system according to the implementation method.

[0020] The remote operation support system comprises a local device 1, a local management device 2 for managing and controlling the local device 1, a remote management device 3, and a network 4. The local device 1 is, for example, an air conditioning unit or 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 via a remote operation screen. The local management device 2 and the remote management device 3 are configured to communicate via the network 4.

[0021] Figure 2 This is a diagram showing the structure of the local management device 2. The local management device 2 includes a memory 21, a processor 22, and a communication circuit 23.

[0022] The memory 21 stores the local management program. The communication circuit 23 communicates with the remote management device 3 via the network 4.

[0023] The processor 22 executes the local management program stored in the memory 21. For example, the processor 22 receives a transmission request from the remote management device 3 via the communication circuit 23, indicating a remote operation screen for remote operation of the local device, and transmits the signal indicating the remote operation screen to the remote management device 3 via the communication circuit 23.

[0024] Figure 3 This is a diagram showing the structure 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 34, and a display device 35.

[0025] The memory 31 stores the remote management program. The input device 34 receives input from the 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.

[0026] The processor 32 executes the remote management program stored in the memory 31. For example, the processor 32 requests the local management device 2 to send a signal representing a remote operation screen for remote operation of the local device via the communication circuit 33. The processor 32 receives the signal representing the remote operation screen for remote operation of the local device via the communication circuit 33, corrects the tags with specified tag names and specified attribute values ​​in the received signal to be inactive or not displayed, thereby correcting the remote operation screen, and displays the corrected remote operation screen on the display device 35.

[0027] Figure 4 This is a flowchart illustrating the process of a remote operation support method performed by a remote operation support system according to an implementation.

[0028] In step S101, the processor 32 of the remote management device 3 launches a web (World Wide Web) browser based on a request input by the user of the remote management device 3 from the input device 34.

[0029] In step S102, the processor 32 of the remote management device 3 receives the URL (Uniform Resource Locator) of the web server of the local management device 2 through the input device 34, which is input by the user of the remote management device 3.

[0030] In step S103, the processor 32 of the remote management device 3 generates an HTTP (Hypertext Transfer Protocol) request based on the URL.

[0031] In step S104, the processor 32 of the remote management device 3 sends an HTTP request through the communication circuit 33.

[0032] In step S104, the processor 22 of the local management device 2 receives an HTTP request through the communication circuit 23.

[0033] In step S105, the processor 22 of the local management device 2 generates an HTTP response.

[0034] In step S106, the processor 22 of the local management device 2 sends an HTTP response through the communication circuit 23.

[0035] In step S107, the processor 32 of the remote management device 3 receives an HTTP response through the communication circuit 33.

[0036] In step S109, if the HTML (Hyper Text Markup Language) file contained in the HTTP response contains a tag specified by the Disable table, the process proceeds to step S110.

[0037] In step S110, if the value of the attribute of the tag specified by the Disable table in the HTML file is consistent with the value of the attribute specified by the Disable table, the process proceeds to step S111.

[0038] In step S111, the processor 32 of the remote management device 3 corrects the HTML file by setting the specified tags in the HTML file to Disable, and stores the corrected HTML file in the memory 31.

[0039] In step S112, if the HTML (Hyper Text Markup Language) file contained in the HTTP response contains the tag specified by the Hidden table, the process proceeds to step S113.

[0040] In step S113, if the value of the attribute of the tag specified by the Hidden table in the HTML file is consistent with the value of the attribute specified by the Hidden table, the process proceeds to step S114.

[0041] In step S114, the processor 32 of the remote management device 3 corrects the HTML file by setting the specified tags in the HTML file to Hidden, and stores the corrected HTML file in the memory 31.

[0042] In step S115, the processor 32 of the remote management device 3 displays the content of the corrected HTML file on the display device 35 through a web browser.

[0043] Figure 5 This is a diagram showing an example of an HTML file received by the remote management device 3. Figure 6 It means according to Figure 5 The image displayed is an HTML file.

[0044] HTML file contains Figure 5 The input tag shown in (1). In this input tag, the value of the type attribute, which represents the shape of the component, is "submit", the value of the name attribute, which represents the name of the component, is "initialize", and the value attribute, which represents the initial value of the component, is "initial setting". Based on this input tag, such as Figure 6 As shown in (A), a text box is displayed that records the "initial settings" as the initial value.

[0045] HTML file contains Figure 5 The input tag shown in (2) has the following properties: In this input tag, the value of the `type` attribute (representing the shape of the component) is "submit", the value of the `name` attribute (representing the name of the component) is "opentest", and the value attribute (representing the initial value of the component) is "open test". Based on this input tag, such as... Figure 6 As shown in (B), a text box is displayed with "Activation Test" as the initial value.

[0046] Figure 7 This is a diagram illustrating an example of the Disable table. The Disable table specifies the tag to be set to Disable using the tag name and the values ​​of one or more attributes. Figure 7 The Disable table specifies that tags with the type attribute value of "submit", the name attribute value of "initialize", and the value attribute value of "initialization" in the input tag should be set to Disable.

[0047] Figure 8 This is a diagram illustrating an example of a Hidden table. A Hidden table specifies tags that are set to Hidden using the tag name and the values ​​of one or more attributes. Figure 8 The Hidden table specifies that tags with the type attribute value of "submit", the name attribute value of "opentest", and the value attribute value of "open test" in the input tag should be set to Hidden.

[0048] Figure 9 This is a diagram showing an example of an HTML file modified by the remote management device 3. Figure 10 It means according to Figure 9 The image displayed is based on the corrected HTML file.

[0049] The revised HTML file includes Figure 9 The input tag shown in (1) is an example of an input tag. "input" is related to... Figure 7 The label name matches the one specified in the Disable table. In this input tag, the value of the type attribute is "submit", the value of the name attribute is "initialize", and the value attribute is "initialization". Therefore, it matches... Figure 7 The value of the attribute specified in the Disable table is consistent with the value of the input tag. Therefore, the input tag is set to Disable. Thus, as Figure 10 As shown in (A), a text box is displayed that will not allow you to enter (inactive) "Initial settings" as an initial value.

[0050] The revised HTML file includes Figure 9 The input tag shown in (2) is an example of an input tag. "input" is related to... Figure 8 The tag name matches the one specified in the Hidden table. In this input tag, the value of the type attribute is "submit", the value of the name attribute is "opentest", and the value of the value attribute is "open test". Therefore, it matches... Figure 8 The value of the attribute specified in the Hidden table is consistent with the value of the input tag. Therefore, the input tag is set to Hidden. Thus, as Figure 10 As shown in (B), the text box that sets "Open Trial" as the initial value is not displayed.

[0051] As described above, according to this embodiment, remote operation of the device can be restricted in a simple way. In this embodiment, setting changes and device control via remote operation can be prohibited, thus ensuring security. Remote operation can be restricted without requiring the local management device's web server to be modified for remote operation. Setting changes and device control can be performed remotely from devices other than the local management device or other remote management devices without restriction.
