Electric energy data recovery device of electric instrument

Provided is an electric energy data recovery device of an electric instrument. The device is characterized in that the device comprises an MCU, a communication module and an ICC interface module or an SPI module, wherein the ICC interface module or the SPI module communicates with a ferroelectric memory and/or an EPPROM memory. The MCU is in coupling connection with other modules, reads electric energy data in a set address in the ferroelectric memory and/or the EPPROM memory via the ICC interface module or the SPI module, and sends the read electric energy data to a data center via the communication module, so processing and analysis for the electric energy data are carried out. The device is capable of quickly and precisely recovering electric energy data when the electric instrument fails to work normally caused by aging of a power supply or abnormity of a single-chip microcomputer.
