AI Technical Summary

Technical Problem

Existing electricity meter equipment suffers from metering errors due to temperature variations over a wide temperature range. In particular, traditional compensation schemes cannot adapt to continuous temperature changes and equipment aging, leading to error drift. Furthermore, relying on additional sensors increases equipment costs and failure rates.

Method used

A dynamic digital compensation method that requires no additional hardware is adopted. By constructing a historical temperature-error relationship database and an adaptive compensation model, the measurement results are adjusted in real time using the existing temperature sensing module of the equipment, realizing a nonlinear mapping between temperature and error, and adapting to measurement error correction over a wide temperature range.

Benefits of technology

Within a wide temperature range of -40℃ to 85℃, the measurement error is controlled within ±1.5℃, which reduces costs and failure rates, improves measurement accuracy and stability, and meets the high-precision measurement requirements of special environments such as extreme cold and high temperature.
