Determination apparatus for intelligent mower location inside or outside virtual line and determination method thereof

Abstract

The invention discloses a determination apparatus for an intelligent mower location inside or outside a virtual line and a determination method thereof. The determination apparatus comprises: a virtual line, which is arranged around a lawn; a direct current output device; at least a permalloy magnetoresistance sensor, which is arranged inside an intelligent mower; and a circuit control device, which is electrically connected with the sensor. The determination method comprises the following steps that: step one, the intelligent mower and the determination apparatus are started; step two, the circuit control device determines whether the intelligent mower is inside the virtual line or outside the virtual line at the beginning; step three, if the intelligent mower is outside the virtual line, the intelligent mower is shut down and is dragged in the virtual line to start the intelligent mower again; step four, if the intelligent mower is inside the virtual line, mowing is carried out and a walking path is programmed; and simultaneously, it is determined whether the intelligent mower is inside the virtual line or outside the virtual line; and step five, if the intelligent mower is inside the virtual line, the intelligent mower is controlled to carry out mowing; if the intelligent mower is outside the virtual line, the intelligent mower is controlled to be enter the virtual line to continuously carry out mowing. According to the determination apparatus and the determination method thereof in the invention, location of an intelligent mower can be determined; and it is determined whether the intelligent mower is inside or outside the virtual line; therefore, the intelligent mower can be effectively controlled to safely and reliably work inside the virtual line of the lawn.

Description

technical field

[0001] The invention relates to a judging device and method for judging whether an intelligent lawn mower is inside or outside a virtual line. Background technique

[0002] The current smart lawn mower randomly looks for a place with grass in the user's yard (virtual lines buried around the yard) to mow grass when it is working, so it is easy to run outside the yard (outside the virtual line). If you go outside the virtual line, you may run out of control and hit people, damage the machine or other accidents. The virtual line passes through an AC signal, and it is impossible to judge the direction of the magnetic induction line inside and outside the virtual line, so as to determine whether the intelligent lawn mower is inside or outside the virtual line. It can only ensure that the machine does not run out of the virtual line when the intelligent lawn mower is originally in the virtual line. It cannot stop working immediately when the machine is outside the...
