Description

Technical Field

[0001] The present application relates to the field of electric bicycle charging detection, and particularly to the field of an electric bicycle charging detection and alarm system for non-intrusive load identification. Background Art

[0002] With the gradual increase in the ownership of residential electric bicycles, there is an urgent need for a system to detect the charging behavior of electric bicycles indoors. After detecting the charging of an electric bicycle, the alarm information will be sent to the supervision platform, so as to facilitate the supervisors to promptly stop the indoor illegal electric bicycle charging behavior within the jurisdiction and reduce the fires caused by the indoor illegal electric bicycle charging of residents.

[0003] When different electrical appliances are operating, the characteristics reflected by their current and voltage are anisotropic. The current and voltage characteristic data during the operation of a certain electrical appliance device are extracted in advance and stored in the system. Then, the current and voltage of the power consumption circuit are monitored, and the monitored values are compared with the current and voltage characteristics of this electrical appliance device stored in the system in real time. When the characteristics match, it can be determined that this electrical appliance device is operating in the power consumption circuit. Those skilled in the art usually refer to this electrical appliance identification technology based on the comparison of current and voltage characteristics as the power fingerprint technology.
