Embodiment Construction

[0034]Wireless power supply technology has always been a hot topic in human research, mainly to transmit power to power supply equipment in a non-contact manner. The research on wireless charging started as early as 1840 when the law of electromagnetic induction was discovered. However, the traditional wireless charging technology has problems such as too short transmission distance and inability to pass through obstacles, so it has not been widely used. In the past two years, magnetic induction coupling resonant wireless energy transfer technology has developed rapidly as an emerging wireless energy transfer technology, and has caused great repercussions in the field of wireless energy transfer. This technology can not only transmit wireless energy for several meters, but also pass through a variety of non-metallic obstacles and transmit high power within a certain distance. As a new type of wireless charging method, magnetic induction coupling resonant wireless charging has ...

Abstract

The invention relates to a wireless charging magnetic induction sensor node device and system and an application method. The sensor node device which comprises a sensor, a microprocessor, a signal sending circuit, a signal receiving circuit, a changeover switch, a coupling coil, a rectifying and filtering circuit, a voltage stabilizing circuit, a charging management circuit, a charging power supply and a numerical control switch is designed. Systematic application architecture and a practical and efficient work application method are constructed. In practical applications, the device is mainlyused in the underground environment. When the sensor node device is buried underground, a charging device wirelessly charges the sensor node device through magnetic resonance coupled resonance, whicheffectively solves the problem of power supply of the underground sensor node and prolongs the life cycle of a wireless sensor network.
