Embodiment Construction

[0074] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0075] A charging method for a wireless rechargeable sensor network, such as figure 1 As shown, the method includes:

[0076] determining the charging traversal path of the wireless rechargeable sensor node according to the remaining lifetime of the wireless rechargeable sensor node;

[0077] Charging the wireless rechargeable sensor nodes on the charging traversal path one by one;

[0078] Wherein, when charging the wireless rechargeable sensor node on the charging traversal path, data transmission is performed according to the path with the lowest cost value from the wireless rechargeable sensor node to the base station or mobile power supply and data collection vehicle, when the wireless rechargeable sensor node is not charged When the wireless rechargeable sensor nodes on the charging traversal path are charging, data tran...

Abstract

The invention provides a charging method and a charging system of a wireless rechargeable sensor network, A method includes A charging traversal path is determined and charged according to the remaining lifetime of the wireless chargeable sensor node when the electric quantity of a wireless rechargeable node is less than a electric quality threshold, and the wireless chargeable sensor node is selected to transmit data to a base station or a path of low value in a mobile power supply and data collection vehicle during the charging process. The technical proposal provided by the invention can solve the problem of energy void due to uneven energy in the wireless rechargeable sensor network, can improve the endurance of the wireless rechargeable sensor network, and can ensure the normal operation of the wireless rechargeable sensor.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a charging method for a wireless rechargeable sensor network. Background technique [0002] A wireless sensor network is a sensor network composed of wireless rechargeable sensor nodes, base stations, and mobile power supply and data collection vehicles; during its operation, the mobile charging vehicle in the wireless sensor network usually uses inductive coupling technology, electromagnetic radiation technology, etc. Wireless energy supply technologies such as magnetic coupling and resonance technology supplement energy for nodes, have good endurance performance, and create conditions for the monitoring system to work in harsh environments. [0003] With the rapid development of wireless sensor networks in recent years, wireless sensor networks are widely used in military, transportation, environmental monitoring, medical and health and other fields, and these monitoring...
