Multi-energy energy collection system based on capacitor pool

Abstract

The invention provides a multi-energy energy collection system based on a capacitor pool, which comprises an electromagnetic energy collection circuit, a light energy collection circuit, a temperaturedifference energy collection circuit, and a multi-element energy collection circuit. The system converts various kinds of energy (electromagnetic energy, light energy and temperature difference energy) into electric energy through the circuit modules and collects the electric energy, the electric energy is released when needed, and thus, the originally wasted energy can be effectively used, energy waste can be avoided to a great extent, the phenomenon that a single energy source collects energy and the collection efficiency is limited is remedied, and stable use of the low-power-consumption internet-of-things equipment can be ensured.

Description

technical field [0001] The invention belongs to the application field of passive sensing, and in particular relates to a multi-energy energy collection system based on a capacitor pool. Background technique [0002] The Internet of Things brings convenience to human life, but batteries are still used as node energy in most of the deployed Internet of Things. The use and periodic replacement of a large number of batteries not only puts a huge burden on the operation of the Internet of Things, but also seriously pollutes the ecological environment we depend on for survival. If the Internet of Things can get rid of its dependence on batteries and use ambient energy to power the nodes of the Internet of Things, then the application of the Internet of Things will be more extensive. [0003] Energy sources are abundant in nature. These energy sources may come from light energy, kinetic energy, mechanical energy, heat energy, and the ubiquitous electromagnetic energy. Light ener...

Problems solved by technology

[0004] Existing energy harvesting technologies have their own shortcomings. Light energy is limited by the use time and environmental conditions, such as continuous cloudy and rainy days with insufficient light, wild nights or underground environments; it is difficult to collect mechanical energy when it is static; The energy that can be brought by the temperature difference, but because the temperature difference in the environment changes little in most cases, the energy harvesting efficiency is extremely low
