[0071] Through the above-mentioned drawings, the specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and text descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiments

[0072] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of the devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0073] First, the nouns involved in the present application are explained:

[0074] Power grid topology model: A power grid topology model is a model used to describe the connection relationships and physical layouts of various electrical components (such as generators, transformers, transmission lines, busbars, loads, etc.) in a power system, presenting the power grid architecture and its characteristics in an abstract mathematical structure and graphical form.

[0075] Work ticket: A work ticket is a document used in power equipment maintenance, repair, and other work to record information such as work tasks, work scopes, safety measures, and work times, clarify the responsibilities of all parties such as work permit issuers, work leaders, and work team members, and ensure the safe and orderly progress of power maintenance work.

[0076] To clearly understand the technical solution of this application, the following details the solutions of the prior art.

[0077] With the progress of technology, the application of intelligent wearable devices in the power industry is becoming increasingly widespread. Especially in power grid outage maintenance work, it can effectively avoid and prevent risks during the period after work completion and before power restoration when not all personnel have been evacuated.

[0078] In the prior art, traditional positioning devices mainly rely on geographical location information maps for display. However, in the complex wiring environment of the power grid, although this method can roughly locate the personnel position, it cannot accurately reflect the specific position of maintenance personnel in the power grid wiring diagram. Figure 1 Schematic diagram for showing the position of maintenance personnel in the geographical location information map, as Figure 1 shown. Although the geographical location information map provides a macroscopic view, it lacks the necessary precision in details, making it difficult for dispatchers to accurately determine whether maintenance personnel are working or evacuating on a specific line or segment.

[0079] Obviously, this limitation poses potential safety hazards to power grid outage maintenance work. Since dispatchers cannot effectively identify the precise position and working status of maintenance personnel, it may lead to failure to confirm that all staff have safely evacuated from the designated line before power restoration, thus triggering personal safety accidents.

[0080] To address the technical problems in the above background art, when the inventor was researching a positioning processing method, it was found that by displaying the real-time position of maintenance personnel obtained from the wearable devices worn by the maintenance personnel in the power grid topology diagram, dispatchers can effectively judge whether the maintenance personnel are working or evacuating on a certain designated line based on this power grid topology diagram.

[0081] Based on the above technical concept of the inventors, the positioning processing method based on the power grid topology provided in this application obtains the power grid topology map of the maintenance area of the maintenance personnel, and obtains the real-time position information of the maintenance personnel through the wearable device worn by the maintenance personnel. Then, according to the real-time position information and the position information of each device in the power grid topology map, the position where the maintenance personnel are located is displayed in the power grid topology map. This method provides technical support for the dispatching and command work of the dispatcher, can effectively prevent personal safety accidents caused by the failure of on-site personnel to evacuate, and is used to achieve the effect of improving the safety of power grid maintenance operations.

[0082] It should be understood that the solution provided in this application can be applied to computer devices in the regional server of the power grid system, such as the provincial main station.

[0083] The following uses specific embodiments to detail the technical solutions of this application and how the technical solutions of this application solve the above technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below in conjunction with the drawings.

[0084] Figure 2 It is a schematic flow chart of the positioning processing method based on the power grid topology provided in the first embodiment of this application. As Figure 2 shown, this method includes:

[0085] S101. Obtain the power grid topology map of the maintenance area of the maintenance personnel, where the power grid topology map includes the power-off equipment and power-off lines in the maintenance area.

[0086] In this solution, before the maintenance operation, the on-site work leader will first make a work ticket for this operation. Among them, the work ticket includes at least the power-off area of this operation, as well as the power-off equipment and power-off lines included in the power-off area. It should be understood that the power-off area includes the maintenance area and the non-maintenance area.

[0087] In this step, before the maintenance operation, the power-off equipment and power-off lines in the maintenance area can be selected in the pre-established power grid topology model according to the maintenance area indicated in the work ticket, and the automatic mapping technology is used to obtain the power grid topology map for visual display, where the power grid topology map includes the power-off equipment and power-off lines in the maintenance area.

[0088] S102. Obtain the real-time position information of the maintenance personnel through the wearable device worn by the maintenance personnel.

[0089] In this step, since the work permit also includes the maintenance personnel who need to carry out maintenance operations, and before the maintenance operations are carried out, a wearable device that each maintenance personnel needs to wear will be distributed. Therefore, when carrying out maintenance operations, the real-time location information of the maintenance personnel can be obtained according to the wearable devices worn by the maintenance personnel. Among them, the location information includes the longitude, latitude and altitude of the location where the maintenance personnel are located.

[0090] In a specific implementation manner, the wearable device of the maintenance personnel can be bound to the work permit by responding to the work permit binding operation of the user.

[0091] In this implementation manner, based on the work supervisor using an electronic device to scan the two-dimensional code in the wearable device worn by the maintenance personnel, the binding of the wearable device and the work permit can be completed. Among them, the electronic device can include a smart phone, a tablet, a computer, etc.

[0092] Optionally, based on the Message Queuing Telemetry Transport (MQTT) communication component in the wearable device, the real-time location information of the maintenance personnel wearing the wearable device can be received.

[0093] In a specific implementation manner, obtaining the real-time location information of the maintenance personnel through the wearable device worn by the maintenance personnel includes:

[0094] Step 1: Receive the encrypted real-time location information sent by the wearable device, where the encrypted real-time location information is obtained by encrypting the real-time location information through the SM4 algorithm;

[0095] Step 2: Decrypt the encrypted real-time location information through the SM4 algorithm to obtain the real-time location information.

[0096] In this implementation solution, in order to ensure the security of information transmission, the wearable device encrypts the real-time location information it sends through the SM4 algorithm in a software and hardware combined manner to obtain the encrypted real-time location information, and sends the encrypted real-time location information to the computer device of the regional server. Therefore, after receiving the encryption sent by the wearable device, the computer device needs to decrypt the encrypted real-time location information through the SM4 algorithm to obtain the real-time location information of the maintenance personnel.

[0097] Among them, the wearable device encrypts the real-time location information it sends by using the SM4 algorithm in a software-hardware combination manner, including: in the wearable device, the wearable device performs operations such as key generation, storage, update, and distribution based on the software therein; based on the dedicated security chip configured therein, according to the key obtained by distribution, it performs operations such as round key addition, S-box transformation, and linear transformation of the SM4 algorithm to generate the encrypted real-time location information. Exemplarily, Figure 3 is the structural schematic diagram of the SM4 algorithm, as Figure 3 shown, the wearable device generates round keys through key expansion, and performs 32 rounds of iterative operations in the basic round function using operations such as round key addition, S-box transformation, and linear transformation, and finally encrypts the 128-bit plaintext into 128-bit ciphertext.

[0098] In the specific application of this solution, the real-time status information of the maintenance personnel can also be obtained through the wearable device worn by the maintenance personnel. Exemplarily, the status information of the maintenance personnel can be obtained according to the living body detection sensor in the wearable device.

[0099] S103. According to the real-time location information and the location information of each device in the power grid topology diagram, display the location of the maintenance personnel in the power grid topology diagram.

[0100] In this step, according to the real-time location information of the maintenance personnel obtained through the wearable device and the location information of each device in the power grid topology diagram, the location of the maintenance personnel can be displayed in the power grid topology diagram, where the location information of the device includes the longitude, latitude, and altitude of the location where the device is located.

[0101] Exemplarily, Figure 4 is the schematic diagram for displaying the location of the maintenance personnel in the power grid topology diagram, as Figure 4 shown, the power grid topology diagram includes the power-off equipment and power-off lines in the maintenance area, as well as the illustration of the maintenance personnel. The dispatcher can accurately judge whether the maintenance personnel are near the power-off equipment or lines in the maintenance area according to the Figure 4 schematic diagram shown.

[0102] In a specific implementation manner, the method in Step 1 to Step 2 can be used to obtain the location information of each device in the power grid topology diagram, and this method includes:

[0103] Step 1. According to the work ticket corresponding to the maintenance personnel, obtain the structured work ticket corresponding to the work ticket, where the structured work ticket includes at least the identifiers, location information, and line relationships between devices in the power grid topology diagram.

[0104] In this step, the structured work ticket corresponding to each work ticket needs to be stored in the computer in advance. Based on this, in the actual application of this solution, the structured work ticket corresponding to the work ticket of the maintenance personnel can be obtained according to the work ticket. Among them, the structured work ticket at least includes the identification, location information of each device in the power grid topology diagram, and the line relationship between each device.

[0105] Specifically, before step 1, the method in steps a to c can be used to obtain the work ticket. This method includes:

[0106] Step a: In response to the user's operation, select at least one power-off device from the power grid topology model.

[0107] In this step, based on the technology of generating a work ticket from a dot diagram, the user needs to determine the power-off area according to the power-off requirements of the maintenance operation, and select the power-off devices included in the power-off area in the pre-established power grid topology model.

[0108] Step b: Generate a structured work ticket according to at least one power-off device and the line relationship between the power-off devices;

[0109] In this step, according to the line relationship between the power-off devices in the power grid topology model, determine the power-off lines between the power-off devices, and generate a structured work ticket according to the power-off devices and the power-off lines.

[0110] Step c: Generate a work ticket corresponding to the structured work ticket based on the structured work ticket.

[0111] In this step, based on the structured work ticket obtained by using the technology of generating a work ticket from a dot diagram, generate the work ticket corresponding to the structured work ticket. Among them, the work ticket at least includes the maintenance personnel who need to carry out this maintenance operation, the power-off area of this maintenance operation, and the power-off lines of the power-off devices included in the power-off area.

[0112] Step 2: Obtain the location information of each device in the power grid topology diagram according to the structured work ticket and the identification of each device in the power grid topology diagram.

[0113] In this step, it is necessary to obtain the location information of each device in the power grid topology diagram according to the identification and location information of each device in the structured work ticket, and the identification of each device in the power grid topology diagram.

[0114] In this implementation manner, a structured work ticket is obtained in advance based on the point-to-ticket technology, and a work ticket including the maintenance personnel required for this maintenance operation and the power outage area of this maintenance operation is generated. In actual maintenance operations, the structured work ticket corresponding to the work ticket can be obtained according to the work ticket of the maintenance personnel, and the position information of each device in the power grid topology can be successfully obtained according to the identification and position information of each device included in the structured work ticket, laying a foundation for displaying the position information of the maintenance personnel on the power grid topology.

[0115] The positioning processing method based on the power grid topology provided in this embodiment obtains the power grid topology of the maintenance area of the maintenance personnel, obtains the real-time position information of the maintenance personnel through the wearable device worn by the maintenance personnel, and then displays the position where the maintenance personnel are located on the power grid topology according to the real-time position information and the position information of each device in the power grid topology. It provides technical support for the dispatching and command work of dispatchers, can effectively prevent personal safety accidents caused by the failure of on-site personnel to evacuate, and is used to achieve the effect of improving the safety of power grid maintenance operations.

[0116] Furthermore, Figure 5 It is a schematic flowchart of the positioning processing method based on the power grid topology provided in the second embodiment of this application. On the basis of the above embodiment, this embodiment introduces in detail how to display the position where the maintenance personnel are located on the power grid topology according to the real-time position information and the position information of each device in the power grid topology:

[0117] Step S201: Calculate the distance between the maintenance personnel and each power outage device in the power grid topology, and the distance between the maintenance personnel and each power outage line according to the real-time position information, the position information of each device, and the line relationship between the devices.

[0118] In this step, according to the real-time position information of the maintenance personnel and the position information of each device, the distance between the maintenance personnel and each device in the topology can be calculated; according to the position information of each device and the line relationship between the devices, the position information of each line can be determined; according to the actual position information of the maintenance personnel and the position information of each line, the distance between the maintenance personnel and each power outage line can be calculated.

[0119] Step S202: Determine the display mode of the maintenance personnel on the power grid topology according to the distance between the maintenance personnel and each power outage device in the power grid topology, the distance between the maintenance personnel and each power outage line, and a preset safety distance threshold.

[0120] In this step, the distances between the maintenance personnel obtained through calculation and each power outage device in the power grid topology map will be calculated. The distances between the maintenance personnel and each power outage line will be compared with a preset safety distance threshold. Based on the comparison results, the display mode of the maintenance personnel in the power grid topology map can be determined, where the display mode is used to indicate whether the maintenance personnel are in a dangerous area or a safe area.

[0121] In a specific implementation manner, the following method can be used to determine the display mode of the maintenance personnel in the power grid topology map:

[0122] Based on the distances between the maintenance personnel and each power outage device in the power grid topology map, the distances between the maintenance personnel and each power outage line, and the preset safety distance threshold, it is determined whether the maintenance personnel are in the dangerous area within the preset range of the power outage device or power outage line; if so, the display mode is determined to be the mode indicating that the maintenance personnel are in the dangerous area; otherwise, the display mode is determined to be the mode indicating that the maintenance personnel are in the safe area.

[0123] Optionally, the safety distance threshold corresponding to each device and line can be determined according to the voltage level of the device or line. Exemplarily, if the voltage level of the device or line is 500V, the safety distance threshold can be set to 5m; if the voltage level of the device or line is 220V, the safety distance threshold can be set to 3m; if the voltage level of the device or line is 35V, the safety distance threshold can be set to 1m; if the voltage level of the device or line is 10V, the safety distance threshold can be set to 0.7m. This application does not limit the selection of the safety distance threshold.

[0124] Step S203: Display the illustration of the maintenance personnel in the power grid topology map through the display mode.

[0125] Exemplarily, if it is determined that the display mode indicates that the maintenance personnel are in the dangerous area, in the power grid topology map, the illustration of the maintenance personnel can be displayed at the device or line closest to them; if it is determined that the display mode indicates that the maintenance personnel are in the safe area, the illustration of the maintenance personnel will not be displayed in the power grid topology map.

[0126] The positioning processing method based on the power grid topology provided in this embodiment calculates the distances between the maintenance personnel and each power outage device in the power grid topology diagram, and the distances between the maintenance personnel and each power outage line according to the real-time position information, the position information of each device, and the line relationship between the devices; then determines the display mode of the maintenance personnel in the power grid topology diagram according to the distances between the maintenance personnel and each power outage device in the power grid topology diagram, the distances between the maintenance personnel and each power outage line, and a preset safety distance threshold; finally, by means of displaying the illustration of the maintenance personnel in the power grid topology diagram in the display mode, the real-time position of the maintenance personnel is successfully displayed in the power grid topology diagram, facilitating the dispatcher to accurately grasp whether the maintenance personnel have safely exited the maintenance area and improving the safety of power grid maintenance operations.
