Forest environment energy collection method

Abstract

A forest environment energy collection method is used for completely utilizing the existing energy of forest environment such as biological electric energy and wind energy and collecting and storing the energy to solve the power supply problem of application of wireless sensor network nodes in the forest. The forest environment energy collection method includes a standing tree soil voltage collection and connection circuit, a power generation small windmill, a wind power collection and voltage doubling rectifying circuit, a standing tree soil electric and wind power automatic switching circuit, a passive boosting circuit and an energy accumulation storage circuit. The collection method is characterized in that voltage signals between stranding trees and the soil where the trees grow and voltage signals generated by the power generation small windmill arranged on the trees under the effect of natural wind in the forest can be collected, the collected voltage signals of the standing trees and the soil where the trees grow and voltage signals generated by the power generation small windmill and passing through the voltage doubling rectifying circuit are compared, the signals with high voltage are automatically connected with the passive boosting circuit, the voltage is boosted to 3v by the passive boosting circuit and collected by a super capacitor, energy is stored, and a lithium battery is charged under the control of a micro loss intelligent charging controller.

Description

technical field [0001] The invention relates to a forest environment energy collection method, which can solve the problem that batteries of wireless sensor network nodes in harsh environments or unmanned forest areas cannot be charged in time or difficult to replace. Background technique [0002] Wireless sensor network is a kind of environmental information collection and monitoring network developed in recent years, which uses wireless communication technology to realize remote data collection, monitoring and control. Due to the limitation of hardware conditions, the nodes of wireless sensor networks are usually powered by batteries, and the battery energy is limited, and the nodes of wireless sensor networks are usually placed in harsh environments or unmanned areas, and the batteries cannot be charged or replaced in time during use. Solving the power supply problem of wireless sensor network nodes has become a research hotspot in related fields. Wireless sensor network...
