Solar active tag

The utility model relates to the RFID technology field, particularly to a solar active tag. The solar active tag comprises an active wireless RFID unit composed of an RF circuit and a microprocessor. The solar active tag further comprises a low voltage solar power supply system and an electric capacity device, wherein the low voltage solar power supply system comprises a solar cell panel, a charge-and-discharge control module, a voltage reduction and stabilization module, and a lightening proof surge protection module; and the solar cell panel, the lightening proof surge protection module, and the charge-and-discharge control module are sequentially connected with the voltage reduction and stabilization module. The solar active tag of the utility model combines the solar cell technology and the electric capacity storage technology together, thereby having long service lifetime. The solar cell continuously converts the luminous energy into the electric energy, thereby charging the electric capacity storage unit with low current. The electric capacity storage unit then provides electric energy to the working circuit of the active electronic label.
