具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
在一个实施例中,请参见图1,本申请实施例提供一种自动行走设备的行走控制方法,包括以下步骤:
S110、通过第一草地识别传感器和第二草地识别传感器获取草地识别信号。
S120、根据草地识别信号,判断第一草地识别传感器与第二草地识别传感器是否检测到非草地。
S130、若第一草地识别传感器与第二草地识别传感器均检测到非草地,控制自动行走设备进行转向。
其中,自动行走设备底部安装有至少一个第一草地识别传感器和至少一个第二草地识别传感器。第一草地识别传感器和第二草地识别传感器可以对称设置,也可以不对称设置。自动行走设备在工作区域朝向某一方向移动,将该方向定义为行走方向。自动行走设备底部安装有位于自动行走设备行走方向两侧的第一草地识别传感器和第二草地识别传感器。第一草地识别传感器和第二草地识别传感器的位置可以根据实际草况进行安装,示例性地,自动行走设备设置有与行走方向平行的中轴线,第一草地识别传感器和第二草地识别传感器可以位于中轴线的两侧。
第一草地识别传感器和第二草地识别传感器的数量可以根据实际草况进行选择,至少一个第一草地识别传感器可以构成第一草地识别传感器组,至少一个第二草地识别传感器可以构成第二草地识别传感器组。可以理解的是,第一草地识别传感器和第二草地识别传感器的数量可以是一个、两个等。
具体地,第一草地识别传感器和第二草地识别传感器对自动行走设备是否处于非草地进行检测,并输出对应的草地识别信号。根据第一草地识别传感器和第二草地识别传感器分别输出的草地识别信号,判断第一草地识别传感器与第二草地识别传感器是否检测到非草地,若第一草地识别传感器与第二草地识别传感器均检测到非草地,控制自动行走设备进行转向。
可以理解的是,若第一草地识别传感器与第二草地识别传感器均检测到非草地,可以控制自动行走设备向任意方向转弯以使自动行走设备尽快回到工作区域。
本实施例中,在第一草地识别传感器与第二草地识别传感器均检测到非草地时,控制自动行走设备进行转向,避免自动行走设备的多次转向,提高自动行走设备的通过性,从而提高自动行走设备的工作效率。
在一个实施例中,控制自动行走设备进行转向,包括:控制自动行走设备每次转向第一预设角度。其中,可以根据实际情况设置第一预设角度的大小,本申请对第一预设角度的大小不做具体限定。
在一个实施例中,第一预设角度为5度至90度。即第一预设角度可以为5度至90度中的随机角度,示例性的,第一预设角度可以为5度、30度、45度、60度、90度。优选地,第一预设角度为5度至60度中的任意随机角度。
本实施例中,为了提高自动行走设备的工作效率,控制自动行走设备每次转向第一预设角度,且第一预设角度为5度至90度,优选地,第一预设角度为5度至60度中的任意随机角度。通过合适的设置自动行走设备每次转向的角度,可以缩短自动行走设备进行转向的时间,提高自动行走设备的工作效率。
在一个实施例中,请参见图2,根据草地识别信号,判断第一草地识别传感器与第二草地识别传感器是否检测到非草地,包括:
S210、根据草地识别信号,确定第一草地识别传感器和第二草地识别传感器均检测到非草地的第一持续时间。
S220、若第一持续时间大于第一预设时间时,则判断第一草地识别传感器与第二草地识别传感器均检测到非草地。
具体地,第一草地识别传感器和第二草地识别传感器对自动行走设备是否处于非草地进行检测,并输出对应的草地识别信号。当第一草地识别传感器和第二草地识别传感器在第一次检测到为非草地时,控制自动行走设备继续前行一段距离,例如10cm至15cm,在前进的这段延迟时间内,持续通过第一草地识别传感器和第二草地识别传感器进行检测。可以根据第一草地识别传感器、第二草地识别传感器分别输出的草地识别信号,确定第一草地识别传感器和第二草地识别传感器均检测到非草地的第一持续时间。将第一持续时间与第一预设 时间进行比较,若第一持续时间大于第一预设时间,则判断第一草地识别传感器与第二草地识别传感器均检测到非草地。本实施例中,通过检测到非草地的草地识别信号的持续时间,提高自动行走设备对非草地判断的准确性。
在一个实施例中,第一草地识别传感器安装于自动行走设备行走方向的第一侧,第二草地识别传感器安装于自动行走设备行走方向的第二侧。若第一草地识别传感器与第二草地识别传感器均检测到非草地,控制自动行走设备进行转向,包括:
若第一草地识别传感器检测到非草地的时刻早于第二草地识别传感器检测到非草地的时刻,控制自动行走设备向第二侧转向。或
若第一草地识别传感器检测到非草地的时刻晚于第二草地识别传感器检测到非草地的时刻,控制自动行走设备向第一侧转向。
可以理解的是,自动行走设备的第一侧与第二侧可以是自动行走设备的左右两侧,本实施例中以第一侧为左侧,第二侧为右侧示例性的进行说明,并不对自动行走设备的第一侧与第二侧做出具体地限定。自动行走设备设置有与行走方向平行的中轴线,自动行走设备的底部安装有位于中轴线左侧的第一草地识别传感器和位于中轴线右侧的第二草地识别传感器。
当草地斑驳时,若第一草地识别传感器检测到非草地的时刻早于第二草地识别传感器检测到非草地的时刻,由于第一草地识别传感器安装于自动行走设备的左侧,则控制自动行走设备向右转向,以使尽快检测到草地。
当草地斑驳时,若第一草地识别传感器检测到非草地的时刻晚于第二草地识别传感器检测到非草地的时刻,由于第二草地识别传感器安装于自动行走设备的右侧,则控制自动行走设备向左转向,以使尽快检测到草地。
在一个实施例中,该方法还包括:在向第一侧转向或向第二侧转向的过程 中,当第一草地识别传感器或第二草地识别传感器检测到草地时,控制自动行走设备停止转向并前进。
当草地斑驳时,若第一草地识别传感器检测到非草地的时刻早于第二草地识别传感器检测到非草地的时刻,由于第一草地识别传感器安装于自动行走设备的左侧,则控制自动行走设备向右转向,在向右转向的过程中,第一草地识别传感器与第二草地识别传感器中的任一传感器检测到草地,自动行走设备停止转向。接着,控制自动行走设备沿着当前方向前移以使自动行走设备处于工作状态,从而提高自动行走设备的工作效率。
当草地斑驳时,若第一草地识别传感器检测到非草地的时刻晚于第二草地识别传感器检测到非草地的时刻,由于第二草地识别传感器安装于自动行走设备的右侧,则控制自动行走设备向左转向,在向左转向的过程中,第一草地识别传感器与第二草地识别传感器中的任一传感器检测到草地,自动行走设备停止转向。接着,控制自动行走设备沿着当前方向前移以使自动行走设备处于工作状态,从而提高自动行走设备的工作效率。
在一个实施例中,请参见图3,该方法还包括以下步骤:
S310、在向第一侧转向或向第二侧转向的过程中,当第一草地识别传感器或第二草地识别传感器检一直检测到非草地,计算自动行走设备的转向角度,并控制自动行走设备进行转向的角度。
S320、若转向角度大于第二预设角度时,控制自动行走设备进行回转至预设方向。
其中,自动行走设备可以安装有方向传感器,比如电子罗盘传感器。自动行走设备在工作区域内沿着任意方向行走,可以通过方向传感器获取自动行走设备行走方向对应的第一角度。获取到自动行走设备行走方向对应的第一角度 后,控制自动行走设备绕着行走方向进行转向,在自动行走设备转向的过程中,可以实时通过方向传感器获取转向后的自动行走设备所处方向对应的第二角度。通过获取的第一角度和第二角度,计算两者的角度差,确定自动行走设备的转向角度。可以理解的是,可以将转向前的起始方向记为0角度,并记录转向了A角度,则确定转向角度为A。进一步地,若自动行走设备的转向角度大于预设角度,控制自动行走设备进行回转至预设方向。其中,预设方向可以根据实际工况而设定。
本实施例中,通过在向第一侧转向或向第二侧转向的过程中,当第一草地识别传感器或第二草地识别传感器检一直检测到非草地,计算自动行走设备的转向角度,且控制自动行走设备进行转向的角度。当转向角度大于第二预设角度时,控制自动行走设备进行回转至预设方向,减少自动行走设备转向所花费的时间,提高自动行走设备的整机通过性。
在一个实施例中,请参见图4,若转向角度大于第二预设角度时,控制自动行走设备进行回转至预设方向,包括以下步骤:
S410、若转向角度大于第二预设角度时,控制自动行走设备回转至转向前的行走方向,并控制自动行走设备沿着转向前的行走方向向后移动。
S420、当向后移动至第一预设距离时,再次控制自动行走设备进行转向。
其中,第二预设角度的选取关系到自动行走设备转向的次数和时间,该第二预设角度太大不能保证自动行走设备工作的效率。第二预设角度太小又会影响自动行走设备的通过性,同时还可能影响用户体验,所以第二预设角度的设置可以根据实际情况进行确定,在本实施例中,第二预设角度例如为90-135度的任意角度,在另外的实施例中,并不限定第二预设角度的具体数值。具体地,若自动行走设备的转向角度大于第二预设角度,并控制自动行走设备沿着转向 前的行走方向向后移动;当向后移动至第一预设距离时,再次控制自动行走设备进行转向。可以理解的是,在某些情况下,自动行走设备沿着转向之前的行走方向可以前进,也可以后退。
第一预设距离的选取关系到自动行走设备的工作效率,该第一预设距离太大不能保证自动行走设备的工作效率。第一预设距离太小又会导致自动行走设备转向次数过多,也会影响自动行走设备的工作效率,同时还可能影响用户体验,所以第一预设距离的设置可以根据实际情况进行确定,此处并不限定第一预设距离的具体数值,比如,第一预设距离可以是15cm至30cm。具体地,若自动行走设备转向角度大于预设角度,控制自动行走设备回转至转向之前的行走方向,且自动行走设备沿着转向之前的行走方向移动一段距离。当自动行走设备移动至第一预设距离时,再次控制自动行走设备绕着转向之前的行走方向进行转向。
本实施例中,若转向角度大于第二预设角度时,控制自动行走设备回转至行走方向,并控制自动行走设备沿着行走方向移动,当移动至第一预设距离时,再次控制自动行走设备进行转向。实现了对自动行走设备转向的控制,防止自动行走设备多次无目的的转向,并进一步地提高了自动行走设备的运行效率。
在一个实施例中,请参见图4,当向后移动至第一预设距离时,再次控制自动行走设备进行转向,包括以下步骤:
S510、获取转向前第一草地识别传感器检测到非草地的时刻和第二草地识别传感器检测到非草地的时刻。
S520、若转向前第一草地识别传感器检测到非草地的时刻晚于第二草地识别传感器检测到非草地的时刻,则控制自动行走设备向第一侧转向。或
S530、若转向前第一草地识别传感器检测到非草地的时刻早于第二草地识 别传感器检测到非草地的时刻,控制自动行走设备继续向第二侧转向。
具体地,获取转向前第一草地识别传感器检测到非草地的时刻和第二草地识别传感器检测到非草地的时刻,将第一草地识别传感器检测到非草地的时刻与第二草地识别传感器检测到非草地的时刻进行比较。
若转向前第一草地识别传感器检测到非草地的时刻晚于第二草地识别传感器检测到非草地的时刻,且第一草地识别传感器安装于自动行走设备的左侧,且为了尽快检测到草地,控制自动行走设备前移或者后退至第一预设距离时,则再次控制自动行走设备向右转向,从而提高自动行走设备的工作效率和通过率。
若第一草地识别传感器检测到非草地的时刻晚于第二草地识别传感器检测到非草地的时刻,且第二草地识别传感器安装于自动行走设备的右侧,且为了尽快检测到草地,控制自动行走设备前移或者后退至第一预设距离时,则再次控制自动行走设备向左转向,从而提高自动行走设备的工作效率和通过率。
在一个实施例中,在自动行走设备前进时,该控制方法还包括:
当仅第一草地识别传感器检测到非草地时,获取第一草地识别传感器检测到非草地的第二持续时间;若第一持续时间大于第二预设时间时,控制自动行走设备向第二侧转向。或
当仅第二草地识别传感器检测到非草地时,获取第二草地识别传感器检测到非草地的第三持续时间;若第三持续时间大于第二预设时间时,控制自动行走设备向第一侧转向。
本实施例中,当自动行走设备运行过程中,在第二预设时间内仅有1个传感器检测到草地,则此时自动行走设备向有草一侧转一定角度后前进或者后退。本实施例中,第二预设时间的选取关系到自动行走设备的工作效率,该第二预 设时间太大不能保证自动行走设备的工作效率。第二预设时间太小又会导致自动行走设备转向次数过多,也会影响自动行走设备的工作效率,同时还可能影响用户体验,所以第二预设时间的设置可以根据实际情况进行确定,此处并不限定第二预设时间的具体数值,比如,预设时间可以是1秒或2秒等。
在一个实施例中,在自动行走设备前进时,该方法还包括:
当仅第一草地识别传感器检测到非草地时,获取第一草地识别传感器检测到非草地的第一运动距离;若第一运动距离大于第二预设距离时,控制自动行走设备向第二侧转向;或
当仅第二草地识别传感器检测到非草地时,获取第二草地识别传感器检测到非草地的第二运动距离;若第二运动距离大于第二预设距离时,控制自动行走设备向第一侧转向。
本实施例中,当自动行走设备运行过程中,在第二预设距离内仅有1个传感器检测到草地,则此时自动行走设备向有草一侧转一定角度后前进或者后退。本实施例中,第二预设距离的选取关系到自动行走设备的工作效率,该第二预设距离太大不能保证自动行走设备的工作效率。第二预设距离太小又会导致自动行走设备转向次数过多,也会影响自动行走设备的工作效率,同时还可能影响用户体验,所以第二预设距离的设置可以根据实际情况进行确定,此处并不限定第二预设距离的具体数值,比如,第二预设距离可以是0.5米。
在一个实施例中,第一草地识别传感器和第二草地识别传感器分别为电容传感器。
在一个实施例中,第二预设角度为90度,需要说明的是,第二预设角度也可以小于或者等于135度。
在一个实施例中,请参见图6,本申请实施例提供的自动行走设备的行走控 制方法包括以下步骤:
S611、通过第一草地识别传感器检测自动行走设备的左侧是否为草地。
S612、通过第二草地识别传感器检测自动行走设备的右侧是否为草地。
S620、当仅有1个传感器检测到草地时,自动行走设备向有草一侧转一定角度后前进。
S630、当第一草地识别传感器与第二草地识别传感器均检测到非草地,获取自动行走设备行走方向对应的第一角度。
S641、若第一草地识别传感器检测到非草地的时刻早于第二草地识别传感器检测到非草地的时刻,控制自动行走设备向右转向并检测草地。
S651、在向右转向的过程中,当第一草地识别传感器或第二草地识别传感器检测到草地时,控制自动行走设备停止转向,并沿着第二角度对应的方向前移。
S661、当第一草地识别传感器与第二草地识别传感器均继续检测到非草地时,判断转向角度是否大于第二预设角度。
S671、若转向角度大于第二预设角度时,控制自动行走设备左转至行走方向,并控制自动行走设备沿着行走方向后退。
S681、当移动至第一预设距离时,再次控制自动行走设备继续向右转向。
S642、若第一草地识别传感器检测到非草地的时刻晚于第二草地识别传感器检测到非草地的时刻,控制自动行走设备向左转向并检测草地。
S652、在向左转向的过程中,当第一草地识别传感器或第二草地识别传感器检测到草地时,控制自动行走设备停止转向,并沿着第二角度对应的方向前移。
S662、当第一草地识别传感器与第二草地识别传感器均继续检测到非草地 时,判断转向角度是否大于第二预设角度。
S672、若转向角度大于第二预设角度时,控制自动行走设备右转至行走方向,并控制自动行走设备沿着行走方向后退。
S682、当移动至第一预设距离时,再次控制自动行走设备继续向左转向。
本实施例中,在自动行走设备运行过程中,在预设时间内仅有一侧的传感器检测到草地,则此时自动行走设备向有草一侧转一定角度后前进,若两个传感器均检测到非草地时,自动行走设备读取方向传感器,获取此时自动行走设备的朝向,并控制自动行走设备开始转向,判断两个传感器谁先检测到草地,则向先检测到草地的方向转弯,转弯同时检测草地,直到转弯到至少其中一个传感器检测到草地时,停止转向。如果连续转弯大于预设角度,比如90°,则自动行走设备回转到自动行走设备转向前的朝向,并后退预设距离,继续向先检测到草地的方向转弯,比如左侧传感器首先检测到非草地,则右转。所转角度可以是5°到90°之间的任意角度。如果两个传感器同时检测到非草地,则转向随机。
