Abstract
(EN) The invention relates to the technical field of electric tools, and particularly discloses a boundary signal generation and detection method, a boundary signal generation system and a mowing robot. The boundary signal generation method comprises the following steps: determining periodic characteristics of an interference signal in a preset space; and determining an initial generation moment of a boundary signal according to the periodic characteristic. According to the boundary signal generation method, the periodic characteristic of the interference signal in the preset space is determined firstly, and then the initial generation moment of the boundary signal is determined according to the periodic characteristic of the interference signal, so the boundary signal can be effectively prevented from being generated at the moment when the interference signal exists or the interference signal is relatively strong, and the boundary signal is prevented from being influenced by the interference signal.
(ZH) 本发明涉及电动工具技术领域,具体公开了一种边界信号的产生和检测方法、产生系统和割草机器人。边界信号的产生方法包括确定预设空间内的干扰信号的周期特性;根据所述周期特性,确定边界信号的起始产生时刻。上述边界信号的产生方法,首先确定预设空间内的干扰信号的周期特性,再根据干扰信号的周期特性确定边界信号的起始产生时刻,由此可有效避免在存在干扰信号或干扰信号较强的时刻产生边界信号,进而防止边界信号受到干扰信号的影响。
