The invention relates to an intelligent charging socket based on Internet of Things. According to the intelligent charging socket, an intelligent charging system which consists of an NB-IOT module, amaster control MCU module, a metering module and a power-supply module is arranged in the interior of a module box. The master control MCU module performs judgment by comparing the real-time data withthe preset threshold value. The metering module acquires the real-time voltage and current of a zero line and a live wire by L line current sampling, N line current sampling and voltage sampling; andthe real-time information of each parameter of the socket is calculated by the metering module. By operating in the mode of the Internet of Things, the socket can be converted into the intelligent socket without changing the socket shape. Meanwhile, the intelligent charging socket is provided with corresponding controlling unit, communication system, measurement system and security mechanism protective functions. Charging can be accomplished by scanning the two-dimensional code by a user. The charging state is monitored in real time and the data is reported timely to a server. Electrical power is switched off automatically by the intelligent socket if an abnormal state occurs, so that user safety can be ensured.
