[0024] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] Data flow process of the overall system architecture of the present invention: The master metering and collection station is responsible for sending metering tasks and collection files to the concentrator APP; the concentrator APP then uses carrier or 485 communication methods to read relevant real-time data and event information from the electricity meters. After collecting this data, the concentrator APP will immediately judge the validity of the data and discard the invalid ones. Once it is recognized that the data is valid and is an important event, the concentrator APP will actively report this event information to the power outage APP, and if it is real-time data, it will be reported to the non-metering APP; subsequently, the power outage APP and the non-metering APP will upload the received data to the power supply service system and the digital substation micro-application respectively through the property management platform to ensure the timeliness and accuracy of the data; the interface should uniformly adopt the MQTT+JSON method;

[0026] Non-metering APP query process for electricity meter files: The non-metering APP requests all file information from the concentrator APP. The format is shown in Table 1 below. If the request type is 0, it means requesting all files from the concentrator APP, and the concentrator APP will reply with all measurement point numbers, electricity meter addresses, port numbers, etc. stored in the parameter library; the non-metering APP is used to send a file query request to the concentrator APP and receive the electricity meter file information returned by the concentrator APP; among them, the non-metering APP can send two types of query requests: a full file query request, used to request the concentrator APP to return all electricity meter file information; a partial file query request, used to request the concentrator APP to return the electricity meter file information within a specified range; the non-metering APP sends a query request to the concentrator APP through the MQTT protocol.

[0027]

[0028] Table 1 Non-metering APP request format for all files

[0029] The non-metering APP requests partial collection file information from the centralized meter reading APP. The format is as shown in Table 2 below. If the request type is 1, it means requesting partial range measurement point number files from the centralized meter reading APP. The centralized meter reading APP will reply with corresponding information such as the measurement point numbers, meter addresses, port numbers, etc. existing in the parameter library, which improves the stability and reliability of the system.

[0033] Table 2 Non-metering APP Request Partial File Format

[0034] Reporting process of real-time data required by the non-metering APP: The digitalized substation area micro-application issues non-metering collection tasks to the property management platform, and the property management platform forwards the corresponding tasks to the non-metering APP on behalf; the non-metering APP reads the existing non-metering collection tasks in the centralized meter reading APP through the corresponding interface of the MQTT protocol, and judges whether non-metering tasks are read. The reading format is as described in Table 3 below. The centralized meter reading APP will reply to the non-metering APP with all non-metering tasks existing in the parameter library, including task numbers, execution frequencies, data types, and specific data items.

[0036]

[0037] Table 3 Non-metering APP Request Collection Task Format

[0038] If non-metering tasks are read, then judge whether the non-metering tasks to be issued are consistent with the non-metering tasks already existing in the centralized meter reading APP. If they are consistent, end. When they are inconsistent, the non-metering APP sends a command to the centralized meter reading APP to request deleting the existing non-metering collection tasks, and issues the collection tasks received from the property management platform to the centralized meter reading APP. The format is as shown in Table 4 below; if non-metering tasks are not read, issue the collection tasks received from the property management platform to the centralized meter reading APP, and the format is as

[0039] shown in Table 4.

[0040]

[0041]

[0042] Table 4 Non-metering APP Set Collection Task Format

[0043] Reporting process for real-time data required by the non-metering APP: The meter reading APP reads the real-time data of the electric meter, such as voltage, current, power, etc., through carrier or 485 communication, and then determines whether these data items belong to the command items of the non-metering collection task. If so, the meter reading APP uploads the real-time data to the non-metering APP in the format specified by MQTT+JSON, as shown in Table 5 below. The uploaded content includes various real-time information, including the electric meter address, reading time, command item, command value, etc.; after receiving the real-time data report, the non-metering APP immediately sends the data to the property management platform, and the property management platform then transmits the data to the digital substation micro-application; otherwise, it ends.

[0044]

[0045] Table 5 Format for reporting real-time data to the non-metering APP

[0046] Reporting process for real-time data required by the power outage APP: The meter reading APP collects important events of the electric meter, such as power outage events, meter cover opening events, etc., through carrier or 485 communication, and then determines whether these data items belong to the command items of the non-metering collection task. If so, the meter reading APP uploads the event data to the power outage APP in the format specified by MQTT+JSON, as shown in Table 6 below. The content information includes the electric meter address, occurrence time, end time, etc.; after receiving the event data report, the power outage APP immediately sends the data to the property management platform, and the property management platform then transmits the data to the power supply service system; if not, the reporting ends.
