By combining the wireless electric energy transmission technology, the solar power supply technology and the wireless electric energy feedback technology, the flexibility and continuity of power supply of the intelligent garbage can are improved, and the problems of resource consumption and the like are solved.
Description
technical field [0001] The invention belongs to the field of wireless energy transmission, and relates to a two-way integrated wireless power supply system for an intelligent trash can and a control method thereof. Background technique [0002] With the implementation of the new regulations on garbage classification, how to correctly classify garbage has become a difficult task. The emergence of intelligent trash cans has made the automatic classification of trash cans a reality. , mobile network, overflow alarm and other functions in one, so the power supply mode of the smart trash can has also become an important factor restricting its further development. At present, there are three main power supply schemes for smart trash cans: wired power supply, battery power supply and solar power supply. Wired powered trash cans need to be placed at fixed points, and the application flexibility is poor; battery powered trash cans need to be replaced periodically, which takes time. ...
