Problems solved by technology

However, due to the fact that the boundary lines of multiple self-driven devices are adjacent, the self-driven device can receive multiple sets of magnetic field signals including its own first magnetic field signal and external magnetic field signals of other self-driven devices. The magnetic field signal is due to the transmission length and The interval time is uncertain, and the sensing unit of the self-driving device cannot distinguish its own first magnetic field signal, which will lead to errors in the judgment of the position information of the self-driving device

Abstract

The invention discloses a self-driven equipment system and a charging station, and the system comprises a boundary line which is used for planning a working area of self-driven equipment; the self-driven equipment automatically walks in the working area for operation; the charging station is electrically connected with the boundary line and is used for generating a coding boundary signal and sending the coding boundary signal to the boundary line; the coding boundary signal flows through the boundary line to generate a first magnetic field signal; the charging station comprises a signal transmitter used for coding in a preset digital modulation coding mode to generate a coding boundary signal; the self-driven equipment is used for receiving the external magnetic field signal and acquiring a decoding boundary signal in a preset decoding mode; and when the decoding boundary signal is matched with the coding boundary signal, determining that an external magnetic field signal received by the self-driven equipment is a first magnetic field signal generated when the coding boundary signal flows through the boundary line. The situation that other external magnetic field signals are mistakenly recognized as the first magnetic field signals is reduced, magnetic field signal misjudgment is reduced, and more accurate position information is obtained.

Description

technical field [0001] Embodiments of the present invention relate to a garden-type electric tool, and in particular, to a self-propelled equipment system and a charging station. Background technique [0002] Self-driving equipment can use sensing technology, positioning technology, boundary recognition technology, full-area coverage path planning technology and autonomous recharging technology to realize fully automatic lawn mowing and maintenance work, without direct human control and operation, greatly reducing labor costs, It is a tool suitable for lawn mowing and maintenance in home gardens and public green spaces. [0003] Existing self-driven equipment usually uses boundary lines to define its working area, and when the self-driven equipment works, it only works within the working area defined by the boundary lines. However, since the boundary lines of multiple self-driven devices are adjacent to each other, the self-driven device can receive multiple sets of magneti...
