Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0041] A charging method for a mobile robot in a wireless charging sensor network system, comprising the steps of:

[0042] (1) First construct a wireless sensor network system, which includes base stations with multiple charging points, sensor nodes with wireless power receiving devices, and mobile robots with wireless charging functions.

[0043] In addition to processing the environment collected by sensor nodes, the base station has access to Group mobile robot charging points, and adopt the largest number of mobile robot configurations. This configuration makes even if a mobile robot cannot be in a dormant state due to failure, there will be a spare mobile robot instead of work, which enh...

Abstract

The invention discloses a charging method for a mobile robot in a wireless charging sensor network system. The system comprises a base station, sensor nodes with wireless power receiving devices and the mobile robot with a wireless charging function, wherein the base station is provided with a plurality of charging points. A moving strategy of the mobile robot, a network energy balance method and a sensor node data processing method are provided on this basis. Data interaction is carried out among the base station, the sensor nodes and the mobile robot in a wireless communication manner. The charging period and each charging quantity are determined according to the energy consumption state of each sensor node. The overall energy utilization efficiency is finally improved by the system; and different energy supplements are carried out on the nodes with relatively fast energy consumption and the nodes with relatively slow energy consumption, so that the network energy consumption is balanced.

Description

technical field [0001] The invention relates to a charging method for a mobile robot in a wireless charging sensor network system, belonging to the technical field of sensor networks. Background technique [0002] In recent years, WSN (Wireless Sensor Networks, wireless sensor network) has been continuously applied in many fields, especially in industrial monitoring, and it is widely used. [0003] Due to the limited energy of sensor nodes, the continuous monitoring of nodes in the application cannot be realized. In the present invention, a mobile robot is equipped with a wireless power transmission device, and according to the path planning algorithm and energy management algorithm in the system, the nodes in the network are Charging, in order to improve the charging efficiency during the charging process, the node energy consumption model is introduced to predict the energy consumption of the node, and obtain the saturation value of the node during the charging process, th...
