The design and development of intelligent power metering system meeting the requirements of data encryption transmission is the key to the optimal operation of energy internet and consumption of large-scale renewable energy. The characteristics of the existing power metering system and the operation requirements of the energy internet are analyzed

and the basic architecture of the intelligent power metering system in the energy internet environment is proposed; The entropy measurement data confusion encryption degree model is set up

and the the data confusion encryption method in the intelligent power metering system is defined; Such main elements as STM32 and BC28 and the economic and technical data of typical cloud services are analyzed

and the implementation method of each subsystem in the intelligent power metering system is given; Some users in a area of certain city in south of Xinjiang are taken as an example

the feasibility of the design and development method of the proposed intelligent power metering system is verified by experiments.
