This invention provides a photovoltaic support bracket full lifecycle
traceability device,
system, and method based on
passive sensing and digital twins. The
traceability device includes a housing and a main control MCU module encapsulated within the housing, as well as a
power management module, an
EEPROM storage module, a sensor monitoring module, and an NFC communication module. The output of the
power management module is connected to other modules to supply power. The main control MCU module is connected to the
EEPROM storage module, the sensor monitoring module, and the NFC communication module respectively, controlling
data acquisition, transmission, and storage, and is responsible for
data scheduling. The
EEPROM storage module stores UID, production batch, tamper-proof status bit, and historical
environmental monitoring data. The sensor monitoring module monitors the ambient temperature,
humidity, and stress state of the support bracket. The NFC communication module enables passive / semi-active near-field communication with a handheld terminal APP. This invention achieves "one item, one code" full-chain management from raw materials to end-of-life recycling, and realizes visualized management of project progress.
