Embodiment 1

[0069] Embodiment 1: The environmental energy harvester may include at least one set of rotating inner skeleton structures 7 and rotating-stationary friction groups. In this example, if figure 1 and figure 2 As shown, the environmental energy harvester includes a top wave fan blade, a rotating inner skeleton structure 7, a rotating-stationary friction group and a high-performance external environment isolation package.

[0070] like figure 1 As shown, the top of the ambient energy harvester is a wave-shaped fan blade, which includes a wave-shaped fan blade 1 and a rotating shaft 2 . The number M of wave-shaped fan blades 1 can be changed according to the size of the environmental energy harvester, but it needs to be ensured that M≥3; this can ensure that the rotation can be smoothly driven by wind energy or water energy in any direction. At the same time, the M pieces of corrugated fan blades 1 have the same bending direction, and this structure can make the generated rota...

Embodiment 2

[0078] Embodiment 2: as Figure 5 As shown, the self-driven forest environment monitoring and fire early warning system is composed of an environmental energy collector, a power management and energy storage module, a low-power wireless sensor node, and a remote wireless monitoring terminal. The environmental energy collector is the embodiment 1 An environmental energy harvester recorded in . The input port of the power management and energy storage module is connected to the output port of the environmental energy collector, and the electrical output of the environmental energy collector is stored in the energy storage capacitor of the power management and energy storage module. The input port and power management of the low-power wireless sensor node are connected with the energy storage capacitor of the energy storage module.

[0079] Preferably, the low-power wireless sensor node includes a sensor and a wireless transmission control module, and its basic function is that ...

Abstract

The invention discloses an environmental energy collector and its early warning system and application method, relates to the field of micro energy technology and micro system, and solves the problem of inconvenient use of batteries and cables of sensing nodes in outdoor environments such as forests. The present invention includes that the rotating inner skeleton structure (7) converts rotational energy into electrical energy through a rotating-stationary friction group; the rotating-stationary friction group includes a comb-toothed metal electrode, a negative friction material layer (8) and a positive friction material layer ( 10), the positive friction material layer (10) is attached to the rotating inner skeleton structure (7), the two comb-tooth-shaped metal electrodes are staggered to surround multiple separation areas, and the negative friction material layer (8) is filled in multiple The blades in the partition area, the positive friction material layer (10) is attached to the blades. The invention utilizes green energy to realize independent power supply and independent operation.

Description

technical field [0001] The invention relates to the field of micro energy technology and micro system, in particular to an environmental energy collector, an early warning system and an application method thereof. Background technique [0002] With the development of Internet of Things technology, wireless sensor networks (WSN) based on data acquisition unit, data transmission unit, data processing unit and energy supply unit are widely used in environmental monitoring. The energy supply unit of traditional WSN relies heavily on batteries and power grids, but due to problems such as power grid configuration and battery life, it will encounter many obstacles when it is used for forest environment monitoring. In order to overcome the disadvantages that conventional energy supply units cannot be applied, the concept of a self-propelled system is accepted. [0003] The proposal of the triboelectric effect ushered in an important change in the energy supply unit of the self-prop...
