Embodiment Construction

[0058] After 2020, mobile communication technology and industry will enter the fifth generation of communication, which will expand economic life from the mobile Internet to the field of the Internet of Things. With the rapid development of LPWA products, consumers are tired of messy cables and batteries that need to be recharged frequently. How to reduce the power consumption of LPWA products or prolong the service life of products has become a problem that needs to be solved.

[0059] There are a variety of near-field and far-field charging wireless technologies currently on the market, including inductive, resonant, ultrasonic and infrared charging, etc. These technologies need to follow different standards. Charging cannot meet the application requirements of IoT products. With the continuous development of wireless radio frequency charging technology, short-distance and medium-distance wireless charging technology has gradually matured, and the current coverage can reach ...

Abstract

The invention discloses a method and equipment for supplying power to LPWA equipment, which are used for solving a problem that the volume of a power supply battery of the LPWA equipment is too largein the prior art. In the embodiments of the invention, the LPWA equipment in an awakening state judges whether to enter a dormant state from the awakening state or not; and after the LPWA equipment enters the dormant state from the awakening state, the battery is stopped to supply the power, and the power is supplied by an energy source provided by wireless power supply equipment which is receivedthrough a radio frequency wireless transmission mode. The electric quantity required by the LPWA equipment is all provided by the battery in the prior art; when the LPWA equipment is in the dormant state, the power is supplied to maintain equipment operation through a wireless radio frequency mode; when the LPWA equipment is in an activated state, the power is supplied by the battery, so that thebattery configured by the LPWA equipment only needs to maintain the electric quantity required by the activated state of the equipment, and thus the electric quantity demand of the battery configuredby the LPWA equipment is reduced, and the volume of the battery is also reduced.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a method and device for supplying power to LPWA (Low Power Wide Area, low power wide area technology) equipment. Background technique [0002] The development of Internet of Things technology has given birth to LPWA technology. LPWA is a new type of wireless access technology that can adapt to M2M (Machine To Machine, machine-to-machine) services and has the characteristics of small traffic and large number of connections. Cost of wireless access network. LPWA technology generally adopts "use of low-frequency band coverage to improve the breadth and depth of coverage, use frequency reuse based on sub-channels to increase the capacity of a single base station, simplify the interaction process between terminals and the network to save terminal energy consumption, and through standardization and industry alliances Formal operation to control costs" and other...
