The utility model discloses a full-life-cycle data traceable terminal, and belongs to the field of power equipment. An existing electric energy meter can only trace back metering errors, cannot recordtoo much data and cannot effectively monitor the electric energy meter. The system comprises a flash storage module, a reading protocol design module, a structure design module, a reading authority control module and a reading and writing program design module. And the flash storage module is used for data storage. According to the utility model, the flash memory is adopted; compared with an existing electric energy meter storage device, the electric energy meter storage device can store a large amount of data, meanwhile, various data processing modules are arranged in the terminal, writing and reading of the data are controlled, comprehensive monitoring and quality tracing of the terminal are facilitated, meanwhile, online upgrading of the terminal can be achieved, the use cost is low, and the user experience is good.
