Intelligent electric meter and electric charge recharging system

Abstract

The invention relates to an intelligent electric meter. The intelligent electric meter comprises a main control module, a data acquisition module, a data processing module, a data storage module, a data display module, a physical unclonable function module and a fingerprint module; the data acquisition module is used for acquiring voltage and current information of the access end of a user; the data processing module is used for processing the voltage and current information of the user and obtaining electric energy information and electric charge; the physical unclonable function module is used for performing unique and unforgeable device numbering of the intelligent electric meter; the fingerprint module is used for entering and identifying fingerprints of the user; the data storage module is used for storing the voltage and current information, the electric energy information, the electric charge and the fingerprint information; the data display module is used for displaying data needed by the user after the fingerprints of the user are identified; and the main control module is used for calling and controlling other various modules. According to the intelligent electric meter and the electric charge recharging system in the invention, the intelligent electric meter has the characteristics of being unique, unforgeable, free from tampering and the like; furthermore, leakage of electricity use information of the user is avoided; and thus, the electricity use privacy of the user is protected.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a smart electric meter and an electricity charging system. Background technique [0002] With the rapid development of smart grids, the demand for intelligent user terminals in countries around the world is also increasing. As smart terminals of smart grids, smart meters are widely used in the construction of smart grids, bringing great convenience to people. However, the existing smart meters still have many technical deficiencies. For example, the user's electricity consumption information is directly displayed on the screen of the smart meter, which may easily lead to the leakage of the user's electricity consumption information and give criminals an opportunity. According to the electricity consumption information, it can be deduced whether the user is going out, and then carry out illegal and criminal activities, posing a threat to the user's personal and property.

Problems solved by technology

However, the existing smart meters still have many technical deficiencies. For example, the user's electricity consumption information is directly displayed on the screen of the smart meter, which may easily lead to the leakage of the user's electricity consumption information and give criminals an opportunity. According to the electricity consumption information, it can be deduced whether the user is going out, and then carry out illegal and criminal activities, posing a threat to the user's personal and property

On the other hand, when the user recharges the electricity bill of the smart meter, he needs to use the device number of the smart meter. Generally, the device number is sent to the user by the power supply company. The user or the user misremembers the device number of the smart meter or the device number of the smart meter is tampered with by criminals, which will cause the user to recharge the electricity bill incorrectly, thus recharging someone else's smart meter

[0003] To sum up, the existing smart meters and recharge methods have problems such as easy disclosure of private information and insecurity, and easy changes of device numbers, which lead to errors in recharge.
