[0073] Specifically, allocating the first work order to the corresponding first operation and maintenance personnel according to the order of the first distances from small to large includes:

[0074] Get the personnel number of the operation and maintenance personnel;

[0075] According to the order of the first distances from small to large, the first distance corresponding to each first terminal is used as the second distance;

[0076] Determining whether the personnel number of the first operation and maintenance personnel corresponding to the first terminal with the smallest second distance is repeated according to the personnel number;

[0077] If there is no duplication, the first work order corresponding to the first terminal with the smallest second distance is assigned to the corresponding first operation and maintenance personnel;

[0078] If there is a duplicate, the second distances of the first operation and maintenance personnel with the duplicate personnel number are compared in order from small to large according to the second distance, and the first work order with the smaller second distance is assigned to the first operation and maintenance personnel.

[0079] In a preferred embodiment of the present invention, there are three idle operation and maintenance personnel, numbered A01, A02 and A03, and the work orders to be processed are numbered B01, B02 and B03. The first distance includes the distance between A01 and B01, B02 and B03, which are 100m, 200m and 300m respectively; the distance between A02 and B01, B02 and B03, which are 100m, 250m and 350m respectively; the distance between A03 and B01, B02 and B03, which are 80m, 190m and 290m respectively. It is judged that the distance between work order B01 and operation and maintenance personnel A03 is the smallest, and work order B01 is assigned to operation and maintenance personnel A03. At this time, the distance between work order B02 and operation and maintenance personnel A01 is 200m, and the distance between work order B02 and operation and maintenance personnel A02 is 250m, so the B02 work order is assigned to the A01 operation and maintenance personnel, and the B01 work order is assigned to the A02 operation and maintenance personnel.

[0080] Preferably, the terminal collected data includes: terminal node voltage, terminal node current and terminal node power; the operation and maintenance personnel status includes: idle, work order receipt and on-site processing; the work order status includes: pending, registered and processed;

[0081] The method further comprises:

[0082] The terminal corresponding to the second work order whose current work order status is registered is used as the third terminal;

[0083] The terminal corresponding to the third work order whose current work order status is processed is used as the fourth terminal;

[0084] The operation and maintenance personnel whose current status is work order signing is used as the second operation and maintenance personnel;

[0085] The operation and maintenance personnel whose current operation and maintenance personnel status is on-site processing shall be regarded as the third operation and maintenance personnel;

[0086] The first terminal, the second terminal, the third terminal, the fourth terminal, the first operation and maintenance personnel, the second operation and maintenance personnel and the third operation and maintenance personnel are marked with different colors on the preset power grid map.

[0087] Pending work orders refer to work orders that have not been assigned to operation and maintenance personnel; registered work orders refer to work orders that have been assigned to operation and maintenance personnel but have not been processed yet, which reflects the work tasks that the operation and maintenance personnel currently need to handle; processed work orders refer to work orders that have been processed and archived, which record the history and completion status of operation and maintenance work. The total number of work orders can be calculated based on the number of pending work orders, registered work orders, and processed work orders. The total number of work orders refers to the total number of all registered, pending, and processed work orders in the system, which reflects the total amount and load of system operation and maintenance work.

[0088] Provide operation and maintenance personnel with positioning devices that support positioning functions (such as smart phones, GPS locators, etc.). The positioning devices regularly upload the location data of the operation and maintenance personnel to the server, and then mark the current location of the operation and maintenance personnel on the GIS map according to the different status of the operation and maintenance personnel, and use different icons or colors to distinguish different personnel. The terminal's location data is regularly collected through the terminal's built-in GPS module or network positioning service, and the collected terminal location data is stored in the database. Then the terminal's location is updated in real time on the GIS map, and the movement of the terminal is displayed using dynamic markers or trajectory lines. Terminals and operation and maintenance personnel in different states are marked with different colors on the power grid map, so that managers can intuitively understand the current operation and maintenance status. This visual management method facilitates rapid identification of problem areas and timely adjustment of strategies, thereby providing higher quality services.

[0089] Indicatively, it also includes:

[0090] Acquire a third number for indicating the number of terminals planned to be installed in the power grid to be managed;

[0091] Calculating the terminal coverage rate of the power grid to be managed according to the first number and the third number;

[0092] According to the terminal coverage rate and a preset coverage rate threshold, determining whether the power grid to be managed meets the collection conditions;

[0093] If so, the first number of power grids to be managed is maintained; if not, a first prompt message is generated according to the terminal coverage rate, so that the operation and maintenance personnel can speed up the progress of the operation and maintenance work according to the first prompt message.

[0094] Based on the terminal coverage rate, operation and maintenance resources can be reasonably allocated to avoid waste of resources; by generating prompt information in a timely manner, operation and maintenance personnel can be prompted to deal with problems in a timely manner, thereby improving the operating efficiency and stability of the power grid; by optimizing the progress of operation and maintenance work, unnecessary operation and maintenance work can be reduced, thereby reducing operation and maintenance costs.

[0095] In another preferred embodiment of the present invention, the terminal online rate refers to the proportion of metering terminals that can communicate normally with the main station and report data to the total number of installed terminals at the current moment or statistical period, which reflects the communication stability and reliability of the terminal; the terminal coverage rate refers to the proportion of metering terminals (such as smart meters, data acquisition terminals, etc.) that have been installed and put into use to the total number of terminals that should be installed. A high terminal coverage rate means that the site already has a good acquisition infrastructure, and the existing terminals can operate normally and transmit data. It also includes the automatic meter reading rate, which is calculated based on the number of terminals that can upload terminal acquisition data and the total number of meter reading terminals. The automatic meter reading rate refers to the proportion of terminals that successfully read and upload electricity data automatically through the metering automation system to the total number of terminals that should be read, which reflects the ability and efficiency of the system's automatic meter reading. It also includes the file consistency rate, which is calculated based on the number of terminals whose terminal file information stored in the system is consistent with the actual installation situation on site to the total number of terminals that have been filed, reflecting the accuracy and completeness of the system file information.

[0096] For the terminal online rate, the terminal online rate index is calculated based on the distributed computing framework, and the online rate index of special transformers, public transformers, and concentrators is summarized and calculated according to the statistical type (real-time online rate, daily average online rate, monthly average online rate), organizational structure (provincial, municipal, district and county bureaus, power supply stations), and statistical caliber (full caliber, direct supply and direct management, county-level subsidiaries). For the terminal coverage rate, the terminal coverage rate index is calculated based on the distributed computing framework, and the collection completeness rate index is summarized and calculated according to the organizational structure (provincial, municipal, district and county bureaus, power supply stations), statistical caliber (full caliber, direct supply and direct management, county-level subsidiaries), time type (time point, time period), and statistical type (real-time, daily, monthly). For the automatic meter reading rate, the automatic meter reading rate index is calculated based on the distributed computing framework, and the automatic meter reading rate index is summarized and calculated according to the organizational structure (provincial, municipal, district and county bureaus, power supply stations), statistical caliber (full caliber, direct supply and direct management, county-level subsidiaries), data type (daily data, monthly data, zero-hour data), and time category (time point, time period).

[0097] Preferably, it also includes:

[0098] Obtain the actual node power of the power grid to be managed;

[0099] Calculating the power error rate of the power grid to be managed according to the actual node power and the terminal node power;

[0100] According to the power error rate and the preset power error threshold, the power accuracy of the managed power grid is evaluated to obtain a power accuracy evaluation result;

[0101] When the power error rate is less than the power error threshold, determining that the power accuracy assessment result is high, and generating a power accuracy assessment report;

[0102] When the power error rate is greater than or equal to the power error threshold, the power accuracy assessment result is determined to be low power assessment accuracy, and a second prompt message is generated and displayed on a preset power grid map.

[0103] In another preferred embodiment of the present invention, the line loss calculation rate is calculated based on the power supply and the power sales. The line loss calculation rate refers to the degree of proximity between the line loss rate calculated by the system and the actual line loss rate, and the line loss calculation rate is compared with the actually measured line loss rate to evaluate the accuracy of the line loss calculation rate. According to the ratio of the load actually carried by the distribution transformer to its rated capacity, the distribution transformer load rate is calculated to evaluate the operating status of the distribution transformer and timely discover overload or underload problems. According to the ratio of the actual published voltage data to the total published voltage data, the voltage publication completeness rate is calculated, and the voltage publication completeness rate is used to evaluate the comprehensiveness and accuracy of the voltage data. The remote inspection rate of the metering device refers to the ratio of the number of metering devices inspected remotely to the total number of metering devices. The statistical method is: the system application indicator statistical unit will record the metering device information of each remote inspection, including the inspection time, inspection results, etc. By calculating the ratio of the number of metering devices inspected remotely to the total number of metering devices, the remote inspection rate of the metering device can be obtained to evaluate the efficiency and effectiveness of the remote inspection work.

[0104] In a preferred embodiment of the present invention, it also includes:

[0105] Obtain the upgrade package and terminal version data of the terminal of the power grid to be managed in real time;

[0106] Determining the upgrade environment of the corresponding terminal according to the upgrade program package;

[0107] According to the upgrade environment, a communication channel with the corresponding terminal is established;

[0108] Sending the upgrade package to the corresponding terminal through the constructed communication channel, so that the terminal performs terminal upgrade according to the upgrade package;

[0109] Compare the terminal version data after the terminal upgrade with the terminal version data before the upgrade to determine whether the terminal has been successfully upgraded;

[0110] If not, resend the upgrade package, re-determine whether the terminal is successfully upgraded, and generate a third prompt message if the second upgrade fails;

[0111] According to the third prompt information and the preset work order format, a work order with a work order status of pending is generated.

[0112] Specifically, by obtaining the latest terminal upgrade package and the currently running terminal version data in real time, and parsing the upgrade package, it is possible to clarify which terminals need to be upgraded and the specific hardware and software environment requirements of these terminals, so that each terminal can use the upgrade package suitable for its specific environment to avoid upgrade failures due to incompatibility. Establishing a stable and secure communication channel is the key to a successful upgrade. This step ensures that the upgrade package can be reliably transmitted to the target terminal and that two-way communication can be performed when necessary to solve possible problems; once the communication channel is established, the upgrade package can be transmitted. After the terminal device receives the upgrade package, it will self-update according to the preset program, which usually includes software replacement, configuration adjustment and other operations. In order to verify the effect of the upgrade, it is necessary to compare the version data before and after the upgrade. If the two are inconsistent, it means that the upgrade may not be completed as expected, and further inspection or re-upgrade is required. If the initial upgrade attempt fails, the system will automatically try to resend the upgrade package and upgrade. If it fails again, a prompt message will be generated to notify the operation and maintenance team of potential problems. When continuous upgrade failures occur, the system will create a new work order based on the predefined work order template and set its status to "pending", which can help operation and maintenance personnel quickly locate the problem and take corresponding measures.

[0113] Indicatively, it also includes:

[0114] Generate a test instruction according to a preset test start time, a preset test end time, and preset test items;

[0115] Sending a detection instruction to each terminal of the power grid to be managed, so that each terminal performs terminal detection according to the detection instruction and generates a terminal detection message;

[0116] According to the terminal detection message and the preset detection message format, judging whether each terminal executes the detection instruction correctly;

[0117] If the terminal detection message is inconsistent with the preset detection message format, determine the terminal error type according to the code in the terminal detection message and the preset error code database;

[0118] If the terminal detection message is consistent with the preset detection message format, it is determined that the terminal executes the detection instruction correctly.

[0119] Indicatively, for traffic statistics, terminal traffic statistics analysis is provided, and traffic statistics by day, month, and year are supported; terminal traffic analysis and statistics are supported according to organization, query time, and statistical type (by organization, by manufacturer); analysis of terminal traffic status (normal, general abnormality, severe abnormality) ratio is supported, and the terminal traffic and excessive traffic of each management unit are displayed in a visual way such as map and list. For terminal whitelist management, it supports the inclusion of terminals that do not require access verification into the whitelist, and supports whitelist maintenance and query.
