[0046] In order to make the objectives, technical solutions and advantages of the present application more apparent, the following will describe example embodiments according to the present application in detail with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application described in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present application.

[0047] Based on the foregoing technical problem, the application provides a power equipment wiring diagram data display method, which comprises the following steps: selecting a current data updating mode from a plurality of preset data updating modes; and updating an initialization xml file according to measurement point data to display a graph element corresponding to the measurement point data in a browser when a trigger condition required by the current data updating mode is met. According to the embodiment of the application, the initialization xml file can be updated according to the measurement point data to display the graph element of different shapes and colors corresponding to the measurement point data in the browser when the trigger condition required by the current data updating mode is met, and the graph element type can be customized according to requirements, so that the display mode is more flexible.

[0048] The scheme of the power equipment wiring diagram data display method according to the embodiment of the application will be described in detail below with reference to the accompanying drawings. The features of each embodiment of the application can be combined with each other on the premise of no conflict.

[0049] Figure 1 A schematic flowchart of the power equipment wiring diagram data display method according to the embodiment of the application is shown. As shown in the figure, the power equipment wiring diagram data display method 100 according to the embodiment of the application can comprise the following steps S101 and S102. Figure 1

[0050] In step S101, a current data updating mode is selected from a plurality of preset data updating modes.

[0051] In one example, the plurality of data updating modes comprises a periodic updating mode and a measurement point value change updating mode.

[0052] The measurement point data comprises at least one group of remote signaling values of the power equipment. When the measurement point data comprises at least two groups of remote signaling values, each remote signaling value in the at least two groups of remote signaling values corresponds to one graph element. Remote signaling refers to the input quantity of remote communication data, such as the open / close state of a circuit breaker or disconnector, the action / restoration of a protection signal, the input / output of an AGC / AVC function, etc., which is usually represented by one or two binary bits. For example, the circuit breaker in the open and closed states corresponds to different graph elements, which can be graph elements of different shapes or graph elements of different colors, which are not limited herein.

[0053] The graph element comprises a scalable vector graphics (SVG) graph.

[0054] In step S102, the initialization xml file is updated according to the measurement point data to display the graph element corresponding to the measurement point data in the browser when the trigger condition required by the current data updating mode is met.

[0055] ​In an embodiment of the present application, the current data updating mode is the periodic updating mode.

[0056] When the trigger condition required by the current data updating mode is met, the initialization xml file is updated according to the measurement point data to display the graph element corresponding to the measurement point data in the browser, including: A1, receiving the first power equipment measurement point data sent by the power equipment every first time interval, and storing the first power equipment measurement point data to the real-time database; A2, acquiring the first power equipment measurement point data in the real-time database every second time interval; A3, updating the initialization xml file according to the first power equipment measurement point data to display the graph element corresponding to the measurement point data in the browser.

[0057] The first time interval can be set as needed. For example, the measurement point data sent by the power equipment is received every 0.1 seconds. After receiving the measurement point data sent by the power equipment each time, the measurement point data can be stored in the real-time database. The second time interval can be set as needed, for example, the real-time database is accessed and the graph element is updated every 1 second. Only the graph element in which the measurement point data has changed can be updated, or all graph elements can be updated.

[0058] In addition, the xml file of the present application generates SVG graphs. When modification of the graph element is needed, the script file needs to be used to update, color, display the telemetry value, and control the content of the corresponding field in the xml file to realize the function.

[0059] XML generally refers to Extensible Markup Language, which is a subset of Standard Generalized Markup Language, and is abbreviated as XML. It is a markup language used to mark electronic files to have structure. The xml file of the present application can be written by a script language, which can include at least one of the following: JavaScript, VBScript, ASP, and PHP.

[0060] In a specific example, as shown in Figure 5 Fig. 1 is a screenshot of the topological relationship of each power equipment and conductor in the real-time database. The incoming line circuit breaker (the equipmentId of the incoming line circuit breaker is 200) is taken as an example for description. The script file calls the equipmentId of the incoming line circuit breaker (for example, the equipmentId of the incoming line circuit breaker is 200) stored in the real-time database, and then the script file finds the graph element specified by the id by searching the graph element template xml file in the system, and refreshes the incoming line circuit breaker graph element on the interface

[0061] Generally, the color, line width and line color have initial values, or the values of the last time. When the xml file is executed, the graph element corresponding to the measurement point data of the incoming line breaker can have new values of the fill color, line width and line color by calling the measurement point data of the incoming line breaker in the real-time database. At this time, the values of the fill color, line width and line color can be directly updated in the xml file, that is, the graph element description is updated, so as to realize the display of the power equipment wiring diagram data.

[0062] In the conventional technology, since the power equipment wiring diagram needs to be recolored every time the measurement point data is received, the efficiency of the display of the power equipment wiring diagram data will be directly affected. The embodiment of the present application can call the graph element that needs to be recolored through the script file, and update the display of the graph element that needs to be recolored, instead of recoloring all the power equipment wiring diagram, so as to improve the efficiency of the display of the power equipment wiring diagram data.

[0063] In one of the examples, according to the first power equipment measurement point data, the initialization xml file is updated, and before the graph element corresponding to the measurement point data is displayed in the browser, the method further comprises: B1, retrieving the first power equipment measurement point data in the real-time database to determine whether the first power equipment measurement point data is stored in the real-time database; B2, when the first power equipment measurement point data is not stored in the real-time database, obtaining the first device topology upstream and downstream power-on logic, judging the graph element corresponding to the power equipment without measurement point data according to the first device topology upstream and downstream power-on logic, then directly calling the graph element corresponding to the power equipment without measurement point data in the initialization xml file, and displaying the graph element corresponding to the power equipment without measurement point data in the browser.

[0064] In a specific example, as shown in FIG. 2(a), it is a transformer graph element schematic diagram before updating, and as shown in FIG. 2(b), it is a transformer graph element schematic diagram after updating. In the following code, the transformer power-on and power-off states are two graph elements, and the following xml file code realizes the switching of the graph elements, and the corresponding xml file code is as follows:

[0074]

[0075] < / object>

[0076] In the embodiments of the present application, some electric power equipment has no measuring point data, for example, the transformer body has no measuring point data, in this case, the graphic element description of the electric power equipment can be updated by the xml file, for example, the fill color, line width and stroke color of the graphic element corresponding to the transformer are directly set in the xml file to realize dynamic update of the graphic element corresponding to the transformer.

[0077] In the displayed graphic element, the graphic element description of the fill color, line width and stroke color of the transformer graphic element can also be set according to the state of the transformer. For example, the measuring points are the transformer winding temperature and core temperature. In the initial state, the winding temperature and core temperature of the transformer are T a = 0.00 ℃, T b = 0.00 ℃, T c = 0.00 ℃, T l = 0.00 ℃, the color of the graphic element corresponding to the transformer; after the measuring point data is updated, the winding temperature and core temperature of the transformer are updated to T a = 33.98 ℃, T b = 36.62 ℃, T c = 33.25 ℃, T l = 60.72 ℃, at this time, the color of the graphic element corresponding to the transformer becomes orange red. This part belongs to refreshing of the telemetry text information, and the principle is the same as that of the refreshing of the telemetry text information introduced below.

[0078] In another embodiment of the present application, the current data update mode is the measuring point value change update mode. When the trigger condition required by the current data update mode is met, the initialized xml file is updated according to the measuring point data of the electric power equipment to display the graphic element corresponding to the measuring point data in the browser, including: at any time, receiving the second electric power equipment measuring point data sent by the electric power equipment, updating the initialized xml file according to the second electric power equipment measuring point data to display the graphic element corresponding to the measuring point data in the browser.

[0079] In one example, updating the initialized xml file includes: calling the graphic element corresponding to the measuring point data by a function in a script file, and sending the graphic element to the browser for display.

[0080] In one example, before updating the initialized xml file to display the graphic element corresponding to the measuring point data in the browser according to the measuring point data, the method includes: associating the graphic element with the initialized xml file.

[0081] In an embodiment of the present application, the initialization xml file includes an element for the graphic element description. The initialization xml file is updated by assigning values to the attributes of the element for the graphic element description in the initialization xml file to generate a graphic element conforming to the graphic element description.

[0082] The element includes at least one of a graphic element shape, a fill color, a line width, and a line color.

[0083] In a specific example, there are multiple ways to change the graphic element shape, such as redrawing the graphic element or processing part of the line of the graphic element.

[0084] The measured point data of the same power equipment can be different, and therefore different graphic elements are needed to represent the measured point data of the same power equipment. In the present solution, different graphic elements are referenced according to the different measured point data (remote signaling values) of the power equipment, and the graphic elements are modified very conveniently, only the graphic element description in the script file needs to be modified, without modifying each instance and without recompilation, and migration is also very convenient. The following takes the circuit breaker trolley graphic element as an example to introduce the method of dynamically updating the display style of the trolley graphic element.

[0096] As shown in FIG. 3(a), it is a trolley graphic element schematic diagram before switching the trolley graphic element style and refreshing the remote measurement value text information update according to the embodiment of the present application; as shown in FIG. 3(b), it is a trolley graphic element schematic diagram after switching the trolley graphic element style and refreshing the remote measurement value text information update according to the embodiment of the present application. In the figures, the measured point data of the trolley in the initial state is: I a = 000.00 A, I b = 000.00 A, I c = 000.00 A. In the next state, the measured point data of the trolley is updated to: I a = 0.58 A, I b = 0.54 A, I c = 0.53 A. Since the phase current of the trolley changes, the graphic element style of the trolley needs to be updated.I a , I b , I c The remote measurement text information of the incoming line cabinet current state of the external power supply changes using the text information refreshing method below. The trolley on-off state depends on the actual device trolley on-off state, and is irrelevant to whether there is current.

[0097] For example, at this time, the interface circuit breaker handcart is in the off state. Subsequently, the substation staff closes the handcart. At this time, the monitoring screen needs to be updated. At this time, the script file first calls the measured point data of the handcart (for example, equipmentId = 76) in the real-time database. Secondly, the graphic element corresponding to the measured point data is determined through the control statement bingdingValue. Then, the updated graphic element is called through the script function setEquipShape() provided by the script file, and the graphic element name after # in the control statement in the xml file is filled into shape = mxgraph.wd_electric.XXX to achieve graphic element switching, thereby changing the display style of the graphic element. The updated handcart graphic element style is shown in Figure 3(b).

[0098] In an embodiment of the present application, the initialized xml file further includes an element for text description. Updating the initialized xml file includes: assigning values to the attributes of the element for text description in the initialized xml file to generate text conforming to the text description, thereby generating text information conforming to the actual telemetry value and displaying it on the browser.

[0099] In a specific example, when updating the text information in the display interface, it is necessary to retrieve all the measured point data of the power equipment from the real-time database. Taking the external power supply incoming line cabinet as an example, the process of dynamically updating the text information of the external power supply incoming line cabinet is introduced below. The following is the xml file code of the text information of the external power supply incoming line cabinet:

[0100] <mxCell parent="1" style="text;html=1;strokeColor=none;fillColor=none;align=center;verticalAlign=middle;whiteSpace=wrap;rounded=0;value="000.00";" vertex="1">

[0101] <mxGeometry as="geometry" height="50" width="80" y="1" x="1" / >

[0102]

[0103] <!-The above are static graphic elements, and the following are graphic elements that can dynamically refresh text information->

[0104] -<object id="UmFyeW21i_9IjySDc-rB-18" equipmentName="External power supply incoming line cabinet multifunction meter" equipmentId="21" label=" <font style＝"font-size:40px"> <font style="font-size:40px">000.00 < / font>"tagDesc="Phase voltage Ua" tagID="286">

[0105] - <mxCell parent="1" style="text;html=1;strokeColor=none;fillColor=none;align=center;verticalAlign=middle;whiteSpace=wrap;rounded=0;fontColor=#ffffff;fontSize=40;" vertex="1">

[0106] <mxGeometry as="geometry" height="50" width="80" y="1" x="1" / >

[0107]

[0108]

[0109] In the present application, the script file calls the measured point data (text information) of the external power line cabinet (for example, equipmentId=21) in the real-time database, the value corresponding to the measured point data is the content of the text information, the description statement in the xml is updated in real time, and the content of the text information in the real-time database is displayed in the display interface.

[0110] As shown in Figure 5 , it is a screenshot of the topological relationship of each power equipment and wire in the real-time database. Taking JXPTSC-JXPT wire (equipment_id is 75) as an example, the upstream (from_id) of JXPTSC-JXPT wire in the entire topological relationship is the incoming line pt handcart (equipment_id is 57), and the downstream (to_id) is the incoming line pt (equipment_id is 56). The logic for determining whether JXPTSC-JXPT wire is colored as the power-on color is as follows: ① Determine the incoming line pt handcart on-off state. At this time, the real-time database pt handcart on-off state remote transmission value is used to determine whether the state of the incoming line pt handcart is on or off; ② Determine whether the incoming line pt handcart is powered on. Search whether the upstream wire JXQF-JXPTSC (equipment_id is 74) of the pt handcart equipment topology is in the power-on state; ③ Determine that the incoming line pt handcart is in the on state and the power-on state. The script file will update the JXPTSC-JXPT wire color description in the xml file to the power-on color through the function, and then this state is successfully refreshed in the browser interface. Please refer to FIG. 4(a) and FIG. 4(b) for the refresh effect.

[0111] In addition, the incoming line pt (equipment_id is 56) shown in FIG. 4(a) and FIG. 4(b) is also consistent with the transformer described in the first specific example, which is a non-measuring point device, and the incoming line pt is a downstream device of the conductor JXPTSC-JXPT (equipment_id is 75) mentioned above. The coloring logic also depends on the power-on state of the topological upstream conductor. If the conductor is live, the pt device is directly colored.

[0112] When the trigger condition required by the current data updating mode is met, the embodiment of the application can update the initialization xml file according to the measuring point data to display the different shapes and colors of the graphic elements corresponding to the measuring point data in the browser. In addition, the graphic element type can be customized according to the requirements, and the display mode is flexible.
