Abstract

An electric energy meter comprises a housing; a data processor, a CPU card seat module and a safety module, and a clock chip circuit are arranged in the housing; the data processor is connected with the CPU card seat module, the safety module, and the clock chip circuit; the data processor employs a FM331x main data processor; the CPU card seat module comprises a CPU card seat circuit; the CPU card seat circuit comprises an interface CARD1 binding post; the work voltage VDD is connected with one end of a resistor R101 and the first pin of the CARD1 binding post in sequence. The electric energy meter has an anti-power stealing function, is higher in usage safety factor, and can save social energy; the electric energy meter employs the cpu card seat module, is strong in information processing ability, safe in information storage, has a lightning protection function, and stronger in interference immunity, thus reducing electric energy meter components damage risks caused by current fluctuations.

Description

technical field [0001] The invention belongs to the technical field of electronic electric meters, and in particular relates to an electric energy meter with a CPU card holder. Background technique [0002] Most of the traditional electric energy meters only have data storage and display function settings, and the meter reading in the power bureau can only be copied by hand. Some users will use some means to steal electricity in order to use it, which affects the safety factor of the meter. There is a risk of electricity theft of the meter, which affects the power supply of the power grid and causes a waste of social energy. [0003] The CPU card is a smart card. The integrated circuit in the card has a microprocessor CPU, a storage unit (including random access memory RAM, program memory ROM (FLASH), user data memory EEPROM) and a chip operating system COS. The CPU card equipped with COS is equivalent to a microcomputer, which not only has the function of data storage, but...
