This invention provides a method and
system for near-end meter reading and calibration via
Bluetooth for power meter maintenance in
transformer substations. The
system includes a power meter module, a maintenance terminal module, and a cloud-based maintenance platform. The maintenance terminal module communicates with the power meter module via encrypted
Bluetooth and synchronizes data with the cloud-based maintenance platform via
wireless communication. This integrates the entire process of meter reading, calibration, recording, and synchronization, which can be completed by maintenance personnel using a general-purpose mobile terminal. This significantly reduces the maintenance time per meter and greatly improves efficiency. Furthermore, a two-way
authentication system, consisting of an identity
verification unit and an identity
authentication unit, establishes an encrypted connection to prevent unauthorized access and data leakage. Simultaneously, an
environmental adaptation unit monitors the ambient temperature,
humidity, and
electromagnetic interference in real time, dynamically adjusting the
Bluetooth communication power and rate to ensure stable connection and reliable
data transmission even in harsh environments.
