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 to solve the problem in the prior art that the power supply battery of the LPWA equipment is too large. In the embodiment of the present invention, the LPWA device in the wake-up state judges whether to enter the dormant state from the wake-up state; after entering the dormant state from the wake-up state, stop the battery for power supply, and use the energy provided by the wireless power supply device received through radio frequency wireless transmission. powered by. In the prior art, all the power required by the LPWA device is provided by the battery. However, in the present invention, since the LPWA device is in the dormant state, it is powered by radio frequency to maintain the operation of the device. When the LPWA device is in the active state, it is powered by the battery. In this way, the LPWA device configuration The battery only needs to maintain the power required to maintain the active state of the device. In this way, the power demand of the battery configured by the LPWA device is reduced, and the size 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...
