ENVIRONMENTAL ENERGY COLLECTION  ELECTRONIC PRICE TAG
摘要:
This application discloses an environmental energy collection electronic price tag, which includes a solar panel (1), an electronic paper display screen (2), a printed circuit board (3) and a super-capacitor (5). The printed circuit board (3) is provided thereon with a signal transceiver antenna and a radio frequency collection antenna. The signal transceiver antenna is configured to send and receive a wireless radio frequency signal, and the radio frequency collection antenna is configured to collect radio frequency signal energy sent by another electronic price tag in environment. An operation frequency of the signal transceiver antenna and an operation frequency of the radio frequency transceiver antenna are same. The super-capacitor (5) is configured to store electric energy converted by the solar panel (1) and the radio frequency collection antenna and provide the electric energy to the printed circuit board (3) and the electronic paper display screen (2). With this application, energies (such as daylight, radio frequency signals, etc.) contained in the surrounding environment can be converted into electrical energy to power the electronic price tag, which meets application requirements of the electronic price tag in a variety of scenes, reduces maintenance frequency of the electronic price tag, and reduces pollution to the environment.
