[0182] Abnormal alarm: When abnormal energy consumption (such as sudden power surge) is detected, an alarm is triggered: an alarm message is sent to the user's WeChat, DingTalk or SMS. The alarm details and suggested handling methods are displayed on the App interface.

[0183] Energy saving suggestions: Provide personalized energy saving suggestions, such as reminding users to use electricity during off-peak hours and recommend shutting down devices that have not been used for a long time.

[0184] Historical analysis: users can view historical energy consumption data by day, week, month, and year. Generate personalized energy consumption reports, including energy consumption overview, energy saving suggestions, and abnormal records.

[0185] Step 7: System maintenance and upgrade

[0186] Module upgrade: users can replace modules according to their needs (such as upgrading communication modules to support faster networks). The system automatically detects the new module and completes initialization.

[0187] Fault monitoring: The system monitors the operating status of each module in real time. When a module abnormality is detected (such as the edge computing module temperature is too high), an alarm is triggered.

[0188] User authority management: different users (such as administrators and ordinary users) access different functions, and the corresponding interface and operation options are displayed according to the authority.

[0189] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
