Wireless communication system, wireless communication method and self-propelled apparatus

Abstract

A wireless communication system, a wireless communication method, and a self-propelled apparatus are provided. The wireless communication system includes a plurality of self-propelled apparatuses. Each of the self-propelled apparatuses is configured to transmit respective moving information and receive moving information of another self-propelled apparatus in the self-propelled apparatuses. At least one of the self-propelled apparatuses forwards the received moving information of another self-propelled apparatus, so that dead spots in the environment in which the self-propelled apparatuses arelocated are reduced, and a communication distance between the self-propelled apparatuses is expanded.

Description

technical field [0001] The invention relates to a communication technology, in particular to a wireless communication system, a wireless communication method and a self-propelled device. Background technique [0002] With the development of science and technology, self-propelled devices have been widely used in various fields, such as self-propelled cleaning devices in the field of environmental cleaning, self-propelled spraying devices or self-propelled mowing devices in the agricultural field Grass machine device, and self-propelled handling device used in the industrial field, etc. [0003] Generally speaking, when there are multiple self-propelled devices in the environment, each self-propelled device can transmit its own movement information to other self-propelled devices through wireless transmission to avoid collisions between multiple self-propelled devices . However, there may be communication dead spots in the environment between two self-propelled devices, so t...

AI Technical Summary

Problems solved by technology

However, there may be communication dead spots in the environment between two self-propelled devices, so that the self-propelled device cannot receive the mobile information of another self-propelled device in the communication dead spot, or the mobile information sent by the self-propelled device in the communication dead spot Movement information cannot be received by another self-propelled device

As a result, communication between multiple self-propelled units can be affected by communication dead spots in the environment

In addition, since the strength of wireless signals will attenuate with the increase of propagation distance, the effective communication distance between multiple self-propelled devices will also be limited
