River monitoring system and method based on array type spherical piezoelectric-triboelectricity composite energy collection

Abstract

The invention discloses a river monitoring system and method based on array type spherical piezoelectric-triboelectricity composite energy collection. The river monitoring method comprises the steps of: collecting the energy caused by the vibration of balls floating on a river due to the flowing of the river through using an array type spherical piezoelectric-triboelectricity energy collector; outputting electric energy in a piezoelectric mode and a triboelectric mode, storing collected energy in a capacitor through using a rectifying circuit and an energy collecting and storing device, and supplying power to all parts of a river monitoring device. When the river monitoring system and the method are applied, the river environment information collected by a river monitoring sensing device is sent to a base station in a wireless mode and then displayed on user terminal equipment. According to the river monitoring system, river kinetic energy is converted into electric energy and stored in the super capacitor, the energy conversion efficiency is high, and self power supply of the river monitoring device is achieved; meanwhile, river energy is fully utilized, and benefits are brought to environment-friendly development.

Description

technical field [0001] The invention relates to the technical field of energy collection, in particular to a river monitoring system and method based on arrayed spherical piezoelectric-triboelectric composite energy collection. Background technique [0002] Flood disasters are a huge threat to people's lives and properties. The flood disaster in 2020 caused 11.22 million disasters in 26 provinces (autonomous regions and municipalities) including Guangxi, Guizhou, Guangdong, Hunan, Jiangxi, and Chongqing, 571,000 people were urgently relocated and resettled, and 213,000 people needed emergency living assistance; more than 9,300 houses The collapse caused 171,000 rooms to be damaged to varying degrees; the affected area of ​​crops was 861,000 hectares; and the direct economic loss was 24.1 billion yuan. In order to better deal with this kind of natural disaster, it is necessary to take certain measures to monitor the river for a long time. [0003] Most of today's river wirel...

Problems solved by technology

However, in the field of energy supply, the traditional energy supply method is still adopted, that is, chemical energy batteries are used as the main energy supply system. Although chemical energy batteries are widely used due to their convenience, they require frequent battery replacement or charging, and material waste , environmental pollution, recycling difficulties and other issues are becoming increasingly prominent
