[0041] The working process of the entire power emergency communication guarantee system is introduced below, which is divided into four steps, each of which is divided into two small steps:

[0042] Step S1: Data collection and local processing

[0043] Step S11: In the field of power facilities, the embedded computer 11 of the edge computing node 1 connects the field devices such as power sensors, monitoring cameras, etc. through multiple communication interfaces 13, collects the operation data (such as voltage, current, temperature, etc.) and field video images of the power facilities, etc.

[0044] Step S12: The embedded computer 11 performs preliminary processing on the collected data, such as data cleaning, filtering, feature extraction, etc., to reduce data volume and improve data quality, and then stores the processed data into the local distributed storage system for subsequent query and analysis.

[0045] Step S2: Data transmission

[0046] Step S21: The communication interface 13 of the edge computing node 1 converts the data into a unified format through the communication protocol conversion module 14, and then sends it to the remote communication interface 22 of the emergency communication management center 2 through wireless data transmission (4G / 5G network). In the process of data transmission, end-to-end encryption technology is adopted to ensure the security and integrity of data.

[0047] Step S22: After receiving the data, the remote communication interface 22 transmits the data to the remote server 21 through gigabit Ethernet.

[0048] Step S3: Centralized storage and management of data

[0049] Step S31: After receiving the data, the remote server 21 stores it into the remote storage device 23 connected through DAS, realizing centralized storage and management of data.

[0050] Step S32: The remote server 21 further analyzes and processes the stored data, such as data mining, fault diagnosis, etc., to provide support for power emergency decision-making.

[0051] Step S4: Emergency decision and response

[0052] Step S41: The emergency communication management center 2 formulates corresponding emergency decisions, such as dispatching emergency repair teams, adjusting power operation parameters, etc., based on the centrally stored and analyzed data and in combination with power emergency plans.

[0053] Step S42: The remote server 21 sends the emergency decision information back to the edge computing node 1 through the remote communication interface 22, and the embedded computer 11 of the edge computing node 1 controls the field devices to perform corresponding operations, such as remotely controlling switches and adjusting transformer taps, etc., to achieve rapid response and emergency disposal.

[0054] The power emergency communication guarantee system disclosed in the embodiment has the following advantages:

[0055] The power emergency communication guarantee system adopts a high-performance embedded computer 11 based on ARM architecture, which has the characteristics of multi-core processing, low power consumption, and high efficiency, meeting the task requirements of data acquisition and processing, and providing strong performance support for local data processing.
