Abstract

The invention relates to a micro energy collector for an Internet of things node, which comprises a solar panel based on a chip BQ25504. The solar panel is connected with a central control module and a super capacitor via a solar MPPT; a micro vibration generator is connected with the central control module and the super capacitor via a voltage stabilization circuit; the solar panel and the micro vibration generator together form mutually-complementary energy supply circuits; the central control module is respectively connected with the super capacitor, a rechargeable lithium battery and a DC-DC conversion circuit; the super capacitor and the rechargeable lithium battery are connected with the DC-DC conversion circuit for providing power for the DC-DC conversion circuit; and the DC-DC conversion circuit is connected with a sensor node. The micro energy collector for the Internet of things node is widely applicable to power supply for the wireless sensor node in various environments, uninterrupted work of the sensor node is realized, and the theoretical value and the application value are good.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things and micro energy collectors, in particular to a micro energy collector oriented to nodes of the Internet of Things. Background technique [0002] With the rapid development of the Internet of Things, an important part of the Internet of Things - wireless sensor networks are also playing an increasingly important role. The nodes of the wireless sensor network have more and more stringent requirements on the lifespan and energy density of the power supply. The traditional power supply method adopts battery power supply, but the battery power supply has the disadvantages of short life and difficult maintenance and replacement. As the number of sensor nodes increases, the labor cost also increases greatly. In order for the nodes to work continuously and reliably, the renewable energy in the environment must be used to the maximum extent. [0003] Solar power supply can provide contin...
