[0029] Specific implementation method 1. Combination Figure 1 to Figure 2 This embodiment is described. The embodiment described in this embodiment is a power system relay protection measurement and control device based on web page interaction. The measurement and control device includes a measurement and control device body 4. It is characterized in that the measurement and control device also includes a configuration module 1, a web page module 2 and a function module 3;

[0030] The configuration module 1, webpage module 2 and function module 3 are all arranged in the measurement and control device body 4;

[0031] Configuration module 1, used for configuring the service type of webpage module 2 for function module 3 in the power device when the power device is started;

[0032] The webpage module 2 is used to receive a service request sent by an external browser, determine the function module 3 involved in the service request, generate a response result including the response data according to the data format of the service type of the webpage module 2 configured by the function module 3 involved in the service request, and feed back the response result to the external browser;

[0033] Functional module 3 is used to respond to the business request through functional module 3 involved in the business request to obtain response data.

[0034] In this embodiment, the usage process of the measurement and control device during maintenance is: first, start the power device and configure the business type of the web page module 2 for the functional module 3 in the power device; then the functional module 3 receives the business request sent by the external browser and determines the functional module 3 involved in the business request; secondly, the functional module 3 involved in the business request responds to the business request to obtain response data; thirdly, the configuration module 1 generates a response result including the response data according to the data format of the business type of the web page module 2 configured by the functional module 3 involved in the business request; finally, the response result is fed back to the external browser.

[0035] Specific implementation method 2: This implementation method further limits the power system relay protection measurement and control device based on web page interaction described in specific implementation method 1. In this implementation method, the web page module 2 is used to determine that the service request includes:

[0036] Parsing the service request to obtain the service type of the service request;

[0037] According to the service type of the service request, the functional module 3 involved in the service request is determined.

[0038] In this implementation, for the case where the service type is to perform a setting operation type, such as modifying a protection setting value, modifying a self-test report frequency, etc., the specific processing of the corresponding service function module is as follows:

[0039] The business function module involved in the business request performs the corresponding setting operation and returns the result of success or failure of the setting operation.

[0040] For example, if the business type is to modify the protection setting, the corresponding business function module modifies the protection setting and returns the result of modification success or modification failure.

[0041] Specific implementation method three: This implementation method further limits the power system relay protection measurement and control device based on web page interaction described in specific implementation method one. In this implementation method, the business type of the business request is to obtain system wiring diagram information, then the module 3 involved in the business request converts the wiring diagram information of the power device into a scalable vector graphics file, and obtains response data including the scalable vector graphics file.

[0042] In this implementation manner, if the service type of the service request is to obtain a system wiring diagram, the wiring diagram information of the power device is converted into an SVG file.

[0043] Specific implementation method four: This implementation method further limits the power system relay protection measurement and control device based on web page interaction described in specific implementation method one. In this implementation method, the request business type of the business request is to obtain menu information, then the function module 3 involved in the business request generates a menu organization structure according to the business function module actually configured in the power device, and obtains response data including the menu organization structure.

[0044] In this embodiment, if the business type of the business request is to obtain menu information, a menu organization structure is generated according to the actual functional configuration of the power device, and the menu organization structure contains the business type index of the web page WEB business module associated with the menu; taking the business type of "obtain menu information" as an example, the data format of the business type named "obtain menu information" is set to "table format", then the web page WEB business module receives the response data including the menu organization structure returned by the business function module involved in the "obtain menu information" business type, and the web page WEB business module organizes the response data in a table format to generate a response result, thereby ensuring that the response data including the menu organization structure is ultimately presented in a table format in an external browser.

[0045] Specific implementation mode 5: This implementation mode further limits the power system relay protection measurement and control device based on web page interaction described in specific implementation mode 1. In this implementation mode, a display screen 5 is provided on the top of the measurement and control device body 4;

[0046] The display screen 5 is used to display the response data obtained by the functional module 3.

[0047] In this embodiment, the response data is displayed on the display screen 5 in a table format or in a menu organization structure format. The display screen 5 is arranged on the top of the measurement and control device body 4 for easy observation.

[0048] Specific implementation method 6: This implementation method further limits the power system relay protection measurement and control device based on web page interaction described in specific implementation method 1. In this implementation method, a ventilation hole 7 is opened on the side wall of the measurement and control device body 4;

[0049] There are multiple ventilation holes 7, and the ventilation holes 7 are strip-shaped structures; the ventilation holes 7 in multiple strip-shaped structures are arranged in parallel.

[0050] In this embodiment, the ventilation holes 7 have the function of ventilation and heat dissipation. The provision of the ventilation holes 7 can prevent the measurement and control device body 4 from overheating to a limited extent, thereby reducing the service life of the measurement and control device.

[0051] Specific implementation method VII. This implementation method further limits the power system relay protection measurement and control device based on web page interaction described in specific implementation method 1. In this implementation method, the measurement and control device further includes a fixing frame 6;

[0052] The fixing frame 6 includes N fixing blocks of block structure, and the N fixing blocks are all fixed on the side wall of the measurement and control device body 4, and the bottom surface of the fixing block and the bottom surface of the measurement and control device body 4 are in the same plane;

[0053] A fixing hole is provided at the center of the fixing block; the fixing hole is circular;

[0054] The N is an integer greater than 1.

[0055] In this embodiment, the fixing block is fixed by screwing a bolt or a screw into the fixing hole, so that the measurement and control device body 4 is in a fixed state, reducing unnecessary damage; at least two fixing blocks are used to fix the measurement and control device body 4. If only one fixing block is used, it is easy to rotate with the bolt or screw as the rotation axis, and the fixing effect cannot be achieved.

[0056] Specific implementation eight, this implementation further limits the power system relay protection measurement and control device based on web page interaction described in specific implementation seven. In this implementation, the number of fixed blocks included in the fixing frame 6 is four;

[0057] The four fixing blocks are respectively fixed at the four corners of the measurement and control device body 4.

[0058] In this embodiment, four fixing blocks have the best fixing effect, and too many fixing blocks waste floor space.

[0059] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
