Abstract: A method, a power adapter and a system for determining a location of the power adapter are provided. The method includes: determining whether the power input plug is engaged with an AC power output wall socket of a power source; if the power input plug is not engaged with the AC power output wall socket, instructing the beacon circuit module to broadcast tag information corresponding to the power adapter; else if the power input plug is engaged with the AC power output wall socket, enabling the tag reader to read a tag circuit of the power source; identifying an identification number detected from the tag circuit; determining a location of the power adapter according to the identification number and a location mapping table; sending a plug notification to a remote control center; and instructing the beacon circuit module for receiving a further tag information of a further power adapter.

Abstract: The present invention provides a power adapter comprising a positioning module for determining its location based on GPS, Wi-Fi access point fingerprinting, RFID, NFC and/or other positioning technologies; sensors for collecting operational/environmental data, including but not limited to air quality, electric current usage, temperature, humidity, altitude, illuminance, infrared radiation, ultraviolet radiation and nuclear radiation; a communication module configured to communicate wirelessly via protocols of various technology standards, including but not limited to cellular (3G/4G etc.), Wi-Fi, Bluetooth and NB-IoT; and a recording module and recognizing module for recording and identifying suspects of surrounding area. With the built-in location tracking, data collection and wireless communication functions, the power adapter of the present invention allows the extension of internet connectivity to existing non-internet-enabled devices without significant infrastructure modifications.
