[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] The maintenance work order generation method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated on server 104 or placed on the cloud or other network servers. The maintenance work order generation method provided in the embodiments of this application can be executed independently by terminal 102 or server 104, or it can be executed collaboratively by terminal 102 and server 104. Taking independent execution by terminal as an example: Data information of the power distribution network supporting power operation is obtained, including at least one of: power equipment information, equipment connection point information, or hierarchical structure information; a power distribution network topology is constructed based on the power distribution network data information; security verification is performed on the power equipment and equipment connection points in the power distribution network topology; a maintenance work order is generated based on the equipment in the power distribution network topology that has failed the security verification, and this maintenance work order is used to instruct the target object to repair the equipment that has failed the security verification.

[0044] The terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, and smart in-vehicle systems. Portable wearable devices can include smartwatches, smart bracelets, and head-mounted devices. The server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0045] In one embodiment, such as Figure 2 As shown, a method for generating maintenance work orders is provided, which can be applied to... Figure 1 Taking the terminal in the example, the explanation includes the following steps:

[0046] S202. Obtain data information of the power distribution network that supports power operation. The data information of the power distribution network includes at least one of the following: power equipment information, equipment connection point information, or hierarchical structure information.

[0047] Among them, the lines that directly supply power to users are called distribution lines, and the network composed of distribution lines is called a distribution network, or simply a distribution grid. The data information of a distribution grid can include at least one of the following: power equipment information, equipment connection point information, or hierarchical structure information.

[0048] Among them, power equipment refers to the relevant equipment that can support power operation, equipment connection point refers to the equipment that connects the power equipment together, and the hierarchical structure is the hierarchical relationship obtained by dividing the power equipment into hierarchical levels based on the functional granularity of each power equipment.

[0049] In this embodiment, the power equipment can be directly connected to other power equipment, or it can be connected to other power equipment through a connection point. The connection point can be directly connected to the power equipment or it can be connected to the power equipment through other connection points. This application does not limit this.

[0050] In some embodiments, the terminal may obtain data information about the distribution network from a geographic information system or a production management system. Data information about the distribution network may also be obtained from other channels, and this application embodiment does not limit this. The distribution network in this application embodiment may also be referred to as the main distribution network, and this name does not constitute a limitation on the embodiments of this application.

[0051] S204. Construct the distribution network topology based on the data information of the distribution network.

[0052] In some embodiments, the data information of the power distribution network includes power equipment information, equipment connection point information, and hierarchical structure information. Based on the hierarchical structure information, power equipment belonging to each level can be identified. For each power equipment within each level, based on the power equipment information of that power equipment, the power equipment and its connection points connected to that power equipment in the upper level, as well as the power equipment and its connection points connected to that power equipment in the lower level, can be identified. Based on the connection relationships between each power equipment and the equipment in the upper and lower levels, the power distribution network topology is determined.

[0053] In some embodiments, after obtaining the data information of the distribution network, an integrated model of the main and distribution networks can be established, and the data topology of the main and distribution networks, i.e., the distribution network topology, can be established based on the integrated model of the main and distribution networks.

[0054] S206. Perform security verification on power equipment and equipment connection points in the power distribution network topology.

[0055] In some embodiments, for power equipment, the operating parameters and rated parameters of the power equipment can be obtained, and the power equipment can be subjected to safety verification based on the operating parameters and rated parameters. If the verification passes, it is determined that the power equipment has no safety problems; if the verification fails, it is determined that the power equipment has safety problems.

[0056] In some embodiments, for a device connection point, the operating parameters, rated parameters, the proportion of power equipment with safety issues among the connected power equipment, and the connection status with the power equipment can be obtained. Based on the obtained information, a safety verification can be performed on the device connection point. If the verification passes, it is determined that the device connection point has no safety issues; if the verification fails, it is determined that the device connection point has safety issues.

[0057] If any electrical device or any device connection point has a safety issue, execute S208. If none of the electrical devices or any device connection points have a safety issue, execute S206 again after a preset time interval.

[0058] S208. Based on the devices in the power distribution network topology that have failed the security verification, generate a maintenance work order. The maintenance work order is used to instruct the target object to repair the devices that have failed the security verification.

[0059] In some embodiments, the terminal can add information such as the device identifier, device location, and device type of the device that failed the security verification in the power distribution network topology to the work order template to obtain a maintenance work order.

[0060] In some embodiments, the terminal can dispatch maintenance work orders to target recipients via SMS, social media applications, email, or other means. The target recipient can be the maintenance personnel's communication address, social media account, email address, etc. The maintenance personnel can view the maintenance work orders, perform maintenance on the corresponding equipment based on the information contained in the work orders, and then report the maintenance results back to the terminal through the target recipient.

[0061] The target object can be specified or it can be bound to a device that has failed the security verification. This application embodiment does not limit this.

[0062] In the above embodiments, data information of the power distribution network supporting power operation is obtained. This data information includes at least one of the following: power equipment information, equipment connection point information, or hierarchical structure information. Based on this data information, a power distribution network topology is constructed. Security checks are performed on the power equipment and equipment connection points in the power distribution network topology. Based on the equipment in the power distribution network topology that fails the security check, a maintenance work order is generated. This work order instructs the target object to repair the equipment that failed the security check. The power distribution network topology in this embodiment can not only be used to display the connection relationships of power equipment but also to provide security protection for power operation and generate maintenance work orders, ensuring that equipment with security issues is repaired promptly.

[0063] In some embodiments, see Figure 3 As shown, the steps for performing security verification on electrical equipment in a power distribution network topology include:

[0064] S301. Identify single-function and non-single-function devices from the power equipment in the power distribution network topology.

[0065] In the power distribution network topology, electrical equipment includes single-type equipment and non-single-type equipment. Single-type equipment can be understood as equipment of the same type that does not exist in other parts of the power distribution network topology, while non-single-type equipment can be understood as equipment of the same type that exists in other parts of the power distribution network topology.

[0066] In some embodiments, it is possible to determine which electrical devices are singular and which are non-singular from all electrical devices in the distribution network topology for subsequent classification verification.

[0067] For single-function devices, security verification is performed via S302; for non-single-function devices, security verification is performed via S303.

[0068] S302. Obtain a first ratio between the operating parameters and rated parameters of the single device; if the first ratio is less than or equal to the corresponding threshold, determine that the single device has passed the security verification.

[0069] In some embodiments, after identifying a single device from all power devices in the distribution network topology, for each single device, its operating parameters and rated parameters can be obtained, and the ratio between the operating parameters and rated parameters can be calculated. For ease of distinction, this ratio is referred to as the first ratio in this embodiment. The first ratio is compared with a preset threshold. If the first ratio is less than or equal to the preset threshold, the single device is determined to have passed the security verification. If the first ratio is greater than the preset threshold, the single device is determined to have failed the security verification.

[0070] S303. Obtain a second ratio between the operating parameters and rated parameters of the non-single device; obtain a third ratio between the operating parameters of the non-single device and the operating parameters of similar devices; if both the second and third ratios are less than or equal to the corresponding thresholds, determine that the non-single device has passed the security verification.

[0071] In some embodiments, after identifying non-singular devices from all power devices in the distribution network topology, for each non-singular device, on the one hand, the operating parameters and rated parameters of the non-singular device can be obtained, and the ratio between the operating parameters and rated parameters of the non-singular device can be calculated. For ease of distinction, this ratio is referred to as the second ratio in this embodiment. On the other hand, the ratio between the operating parameters of the non-singular device and the operating parameters of similar devices can be obtained. For ease of distinction, this ratio is referred to as the third ratio in this embodiment. The second ratio is compared with a preset threshold, and the third ratio is also compared with a preset threshold. If the second ratio is less than the preset threshold, and the third ratio is also less than the preset threshold, it is determined that the non-singular device has passed the security verification. If the second ratio is greater than or equal to the preset threshold, and / or the third ratio is greater than or equal to the preset threshold, it is determined that the non-singular device has failed the security verification.

[0072] It should be noted that the preset thresholds used for comparison with the first ratio, the preset thresholds used for comparison with the second ratio, and the preset thresholds used for comparison with the third ratio can be the same or different, and the embodiments of this application do not limit this.

[0073] Among them, the similar equipment of non-single equipment can be power equipment at the same level as the non-single equipment, or it can be power equipment connected to the same equipment connection point and belonging to the same type. This application embodiment does not limit this.

[0074] In the above embodiments, single-function devices and non-single-function devices are identified from the power equipment in the power distribution network topology. For single-function devices, a first ratio between the operating parameters and rated parameters of the single-function device is obtained. If the first ratio is less than or equal to a corresponding threshold, the single-function device is determined to have passed the security verification. For non-single-function devices, a second ratio between the operating parameters and rated parameters of the non-single-function device is obtained. A third ratio between the operating parameters of the non-single-function device and the operating parameters of similar devices is obtained. If both the second and third ratios are less than or equal to the corresponding thresholds, the non-single-function device is determined to have passed the security verification. This method can promptly detect power equipment with security issues, thereby improving the safety of power operation.

[0075] In some embodiments, see Figure 4 As shown, the steps for performing security verification on device connection points in a power distribution network topology include:

[0076] S401. Obtain the proportion of electrical devices that have not passed the security verification among the electrical devices connected to the device connection point.

[0077] S402. Obtain the fourth ratio between the operating parameters and the rated parameters of the equipment connection point.

[0078] S403. Obtain the connection status between the device connection point and the power equipment.

[0079] S404. If the ratio is greater than the preset ratio, or if the third ratio is greater than the set value, or if the connection status indicates that the device connection point cannot be properly connected to the power equipment, it is determined that the device connection point has failed the security verification.

[0080] In some embodiments, for each device connection point in the power distribution network topology, on the one hand, the number of power devices connected to the device connection point that failed the security verification is obtained, and the proportion of the number of power devices that failed the security verification to the total number of power devices connected to the device connection point is calculated. On the other hand, the operating parameters and rated parameters of the device connection point are obtained, and the ratio between the operating parameters and rated parameters of the device connection point is calculated. For ease of distinction, this ratio is referred to as the fourth ratio in this embodiment. Furthermore, the connection status between the device connection point and the power equipment is obtained. If the above ratio is greater than a preset ratio, or if the fourth ratio is greater than a set value, or if the connection status indicates that the device connection point cannot connect to the power equipment normally, it is determined that the device connection point has failed the security verification. If the above ratio is less than or equal to a preset ratio, and the fourth ratio is less than or equal to a set value, and the connection status indicates that the device connection point can connect to the power equipment normally, it is determined that the device connection point has passed the security verification.

[0081] In the above embodiments, the proportion of electrical equipment connected to the device connection point that failed the safety verification is obtained; a fourth ratio between the operating parameters and rated parameters of the device connection point is obtained; the connection status between the device connection point and the electrical equipment is obtained; if the proportion is greater than a preset proportion, or if the fourth ratio is greater than a set value, or if the connection status indicates that the device connection point cannot connect to the electrical equipment normally, it is determined that the device connection point has failed the safety verification. This method can not only detect safety problems in electrical equipment but also safety problems in device connection points, allowing for timely repair of the device connection points and greatly improving the safety of power operation.

[0082] In some embodiments, the maintenance work order generation method provided in this application further includes: obtaining historical time points when each power device in the power distribution network topology experiences anomalies, and historical time points when each device connection point experiences anomalies; for each power device, determining whether the current power device has a periodic fault based on the historical time point when the current power device experiences anomalies, and if the current power device has a periodic fault, providing a fault warning for the current power device based on the fault cycle corresponding to the current power device; for each device connection point, determining whether the current device connection point has a periodic fault based on the historical time point when the current device connection point experiences anomalies, and if the current device connection point has a periodic fault, providing a fault warning for the current device connection point based on the fault cycle corresponding to the current device connection point.

[0083] In some embodiments, operating status data of power equipment can be recorded, including historical time points when anomalies occurred, and the historical time points when anomalies occurred can be obtained from the operating status data.

[0084] In some embodiments, any power device in the distribution network topology can be considered as the current power device. Based on the historical time points of anomalies in the current power device, it can be determined whether the current power device has periodic faults. If the current power device has periodic faults, a fault warning is issued before the next fault cycle arrives. If the current power device does not have periodic faults, a first average of the time intervals between two consecutive anomalies is calculated based on the historical time points of anomalies in the current power device. When the time without anomalies in the current power device reaches the first average, a fault warning is issued. The above operations can be performed on each power device in the distribution network topology, thereby enabling fault warnings for power devices with potential safety hazards. This allows maintenance personnel to inspect power devices with potential safety hazards in advance, avoiding the negative consequences of faults.

[0085] In some embodiments, the operating status data of the device connection point can be recorded. The operating status data includes historical time points when anomalies occur, and the historical time points when anomalies occur can be obtained from the operating status data.

[0086] In some embodiments, any device connection point in the power distribution network topology can be designated as the current device connection point. Based on historical anomalies at the current device connection point, it can be determined whether a periodic fault exists. If a periodic fault exists, a fault warning is issued for the current device connection point before the next fault cycle arrives. If no periodic fault exists, a second average of the time intervals between two consecutive anomalies is calculated based on historical anomalies at the current device connection point. A fault warning is issued when the duration of no anomalies at the current device connection point reaches the second average. The above operations can be performed on every device connection point in the power distribution network topology, thereby enabling fault warnings for device connection points with potential safety hazards. This allows maintenance personnel to inspect potential device connection points in advance, avoiding negative consequences from faults.

[0087] In some embodiments, when recording the operating status data of power equipment, the rated status parameters of the power equipment can be recorded, and the operating status parameters of the power equipment can also be recorded. The difference between the operating status parameters recorded in the kth time and the operating status parameters recorded in the 1st time can be calculated, where k is greater than 1, and these differences are recorded. The rated status parameters and these differences can be used as the operating status data of the power equipment.

[0088] In some embodiments, for each power device, the difference values ​​in the operating status data of the power device can be extracted, a fitting curve can be constructed based on these difference values, and the future difference values ​​can be predicted by the fitting curve. If the future difference values ​​exceed the set safety value, it is determined that the power device may have a safety problem in the future, and an early warning is issued for the power device.

[0089] In some embodiments, when recording the operating status data of the device connection point, the rated status parameters of the device connection point can be recorded, and the operating status parameters of the device connection point can also be recorded. The difference between the operating status parameters recorded in the kth time and the operating status parameters recorded in the 1st time can be calculated, where k is greater than 1, and these differences are recorded. The rated status parameters and these differences can be used as the operating status data of the device connection point.

[0090] In the above embodiments, historical time points of anomalies in each power device and each device connection point in the power distribution network topology are obtained. For each power device, based on the historical time points of anomalies, it is determined whether the current power device has periodic faults. If periodic faults exist, a fault warning is issued based on the corresponding fault cycle. For each device connection point, based on the historical time points of anomalies, it is determined whether the current device connection point has periodic faults. If periodic faults exist, a fault warning is issued based on the corresponding fault cycle. This enables fault warnings for power devices and device connection points with potential safety hazards, allowing maintenance personnel to inspect these devices and connection points in advance and avoid negative consequences from faults.

[0095] For single-function devices, S504 determines whether the security verification has passed. For non-single-function devices, S505 determines whether the security verification has passed. For device connection points, S506-S509 determine whether the security verification has passed.

[0096] S504. Obtain a first ratio between the operating parameters and rated parameters of the single-function device; if the first ratio is less than or equal to the corresponding threshold, determine that the single-function device has passed the security verification.

[0101] S509. If the ratio is greater than the preset ratio, or if the fourth ratio is greater than the set value, or if the connection status indicates that the device connection point cannot be properly connected to the power equipment, determine that the device connection point has failed the security verification.

This work order instructs the target object to repair the equipment that failed the security check. The power distribution network topology in this embodiment can not only be used to display the connection relationships of power equipment but also to provide security protection for power operation and generate maintenance work orders, ensuring that equipment with security issues is repaired promptly.
