技术领域
本发明涉及自动割草机及其控制方法，特别是一种具有修边功能的自动割草机及其控制方法。
背景技术
随着科学技术的发展，智能的自移动设备为人们所熟知，由于自移动设备可以自动预先设置的程序执行预先设置的相关任务，无须人为的操作与干预，因此在工业应用及家居产品上的应用非常广泛。
以自动割草机为例，自动割草机一般在草地上工作，由用户设定其工作区域，自动割草机检测与工作区域的相对位置关系，使其保持在工作区域内，防止走出边界。自动割草机的切割模块一般为刀片等刚性元件，在其高速运动割草的过程中，容易对人体或其他物体造成伤害，为了避免这种伤害，切割模块周围通常安装有护罩。而为了兼顾自动割草机的通过性要求，护罩保持在一定的高度，且水平方向上与切割模块存在一定距离。也就是说，当自动割草机行走在工作区域边界上，包括障碍物边界，切割模块与实际边界之间仍然存在一段距离，而这段距离造成了草地上存在自动割草机无法切割到的区域，需要用户进行二次处理。

具体实施方式
下面将结合附图对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
参考图1-图11，自动割草机包括壳体100，安装于壳体100的移动模块、切割模块300、修边模块200、检测模块，移动模块包括由驱动马达的驱动轮110和不受驱动马达驱动的从动轮120，检测模块用于检测工作区域边界。自动割草机还包括控制模块，用于控制移动模块、切割模块或修边模块，从而控制自动割草机移动和工作。切割模块300包括切割驱动部和切割部，切割驱动部驱动连接切割部，切割部包括切割元件。修边模块200包括修边驱动部和修边部，修边驱动部驱动连接修边部包括修边元件，修边部工作形成修边区域，修边区域超出壳体100。本实施例中，修边元件的至少一 个特性不同于切割元件，如材质不同，锋利程度不同，重量不同、大小不同等等。
通过修边模块200和切割模块300配合，自动割草机可以扩大修剪范围，能够修剪工作区域边缘一带的草等植物，或者减少工作区域边缘一带的草等植物没有被修剪的范围，极大降低了用户的工作量，提高了用户工作效率和农业生产效率。
可以理解的是，本实施例提供的自动割草机还包括检测模块、通信模块或定位模块等，用于帮助自动割草机维持在用户设定的工作区域内工作，并实现避障等功能。工作区域可以为整块区域或中间具有假山、湖泊等障碍物的区域；工作区域可以为草坪、田地、花园等地形。在一些实施例中，自动割草机可以通过通信模块接收远程设备的发送的信号，远程设备可以包括服务器、用户设备等，控制模块可以根据通信模块接收的信号控制自动割草机进行相应的动作。
本实施例中，壳体100的纵向为壳体的行走方向；壳体100的横向为垂直于壳体的行走方向和高度方向。
如图2所示，在一个实施例中，切割模块300包括刀盘和安装于刀盘的切割元件，修边模块200包括打草头及安装与打草头的打草绳，切割模块300以第一转轴旋转形成切割区域，切割区域具体为由切割元件旋转形成的区域，修边模块200以第二转轴旋转形成修边区域，修边区域具体为由打草绳旋转形成的区域。
在一个实施例中，切割模块300可以设置在壳体100底部的任意位置；可选地，切割模块300偏离壳体100的纵向的中轴线设置，且修边模块200与切割模块300分别设置在壳体100的中轴线的两侧，以使该切割模块300与修边模块200配合可以更好的修剪工作区域内及其边缘一带的草等植物，以使自动割草机的结构更加紧凑，使得壳体100能够同时容纳修边模块200和切割模块300，而避免大幅度增加自动割草机的长度或宽度。
在一个实施例中，沿壳体100高度方向，修边驱动部的投影相对于壳体100位置固定。通过令修边驱动部的投影相对于壳体100位置固定，以简化修边模块200的结构，进而简化自动割草机的结构。
如图2所示，在一个实施例中，沿壳体100高度方向，第二转轴在高度 方向上的投影位于壳体100内部，进一步的，修边模块200的主体部分位于壳体100。因此，在正常工作情况下，自动割草机可以最大限度地保持原有的移动和工作方式，而不受修边模块200的影响。
在一个实施例中，修边区域的至少部分超出壳体100，当自动割草机沿墙或其他障碍物行走时，超出壳体100的修边区域能够实现对障碍物边缘的完全切割。
在一个实施例中，修边模块200包括用于修剪植物的柔性修剪元件210，柔性修剪元件210包括打草绳、柔性塑料刀片或柔性橡胶刀片，或者其他结构；可选地，柔性修剪元件210在碰到人体、篱笆、墙体等物时可以发生形变，或者柔性修剪元件210在碰到人体、篱笆、墙体等物时缩回柔性塑料刀片或柔性橡胶刀片等刀片，而减少对人体、篱笆、墙体等物的损坏，尤其是减少或者避免人体的损伤；柔性修剪元件210在碰到草或者类似于草的植物时，基本不发生形变，以确保柔性修剪元件210可以修剪草或者类似于草的植物。
在一个实施例中，切割模块300包括用于修剪植物的刚性切割元件，如刚性刀片等结构，因此切割模块300接触人体、篱笆、墙体等物时损坏相对更大，因此，在横向上，切割模块300距离壳体100边缘的距离相对较大，以利用壳体100进行防护。而为了实现切割到边，修边模块200产生的修边区域超出壳体100。若第二转轴与中轴线的距离大于等于第一转轴与中轴线的距离，则导致修边区域的半径大于切割区域的半径，修边模块200会对在切割模块300工作的区域重复工作，提高修边模块200的能耗。因此，本实施例中，以第一转轴与中轴线的距离为第一距离，以第二转轴与中轴线的距离为第二距离，第一距离小于第二距离。
在一个实施例中，修边模块200的修边区域的行走轨迹与切割模块300的切割区域的行走轨迹的重叠最大尺寸不小于5mm；以避免修边模块200的修剪区域与切割模块300的切割区域之间存在盲区，进而避免靠近工作区域的边缘一带的草等植物不能被修剪。
可选地，修边模块200的修边区域的行走轨迹与切割模块300的切割区域的行走轨迹的重叠最大尺寸为5mm、6mm、8mm、10.5mm或者20mm等，重叠区域的大小可以根据自动割草机的结构或工作场景等进行确定，不作具体 限制。
本实施例中修边模块200的修边区域的行走轨迹与切割模块300的切割区域的行走轨迹的重叠，包括修边模块200的修边区域与切割模块300的切割区域重叠或者不重叠的方式。例如，修边模块200的修边区域与切割模块300的切割区域在壳体100高度方向的投影具有重叠部分；又如，修边模块200的修边区域与切割模块300的切割区域在壳体100高度方向的投影间隔设置，但是修边模块200的修边区域与切割模块300的切割区域在壳体的横向的投影具有重叠部分；又或其他设置方式。
在一个实施例中，以第一转轴到中轴线的距离为第一距离，以第二转轴到中轴线的距离为第二距离，第二距离与第一距离的差值小于等于主切割区域与辅助切割区域的半径之和。在移动过程中，切割模块300工作后的区域约为宽度等于主切割区域直径的区域a，修边模块200工作后的区域约为宽度等于辅助切割区域直径的区域b。若区域a和区域b在横向上存在间隙，即第二距离与第一距离的差值大于主切割区域与辅助切割区域的半径之和，就导致切割模块300和修边模块200工作后在障碍物周围仍然留有未切割区域。这样，控制模块控制移动模块与工作区域边界之间的相对距离再次沿着工作区域边界行走，从而实现对未切割区域的切割。这种工作方式不仅增加了控制模块的负荷，也降低了自动割草机的工作效率。因此，当第二距离与第一距离的差值小于等于主切割区域与辅助切割区域的半径之和时，区域a和区域b在横向上相切或相交，确保切割模块300和修边模块200工作后障碍物周围已经实现完全切割。
在一个实施例中，工作区域边界可以是由用户布置在工作区域边缘或边缘附近的边界线或其他信号发生装置，也可以是由工作区域中篱笆、花坛等形成的物理边界，也可以是由自动割草机识别工作表面或定位等方式确定的界限。相应的，检测模块可以包括检测边界信号的传感器，检测物理边界的传感器，检测工作表面的传感器或定位传感器等。
在一个实施例中，修边模块200的修边区域与切割模块300的切割区域在壳体100高度方向上的投影不重叠。若修边区域和切割区域存在重叠，当修边模块200和切割模块300在同一高度，修边模块200和切割模块300同时启动会造成相互干扰，导致切割元件和修边元件在工作过程中接触而造成 损坏。因此，修边区域与切割区域不重叠能够提高修边元件和/或切割元件的使用寿命，从而减少用户干预次数。
在一个实施例中，控制模块用于控制移动模块以使自动割草机沿着第一方向行走工作区域边界时，控制切割驱动部以驱动切割模块300工作和/或控制修边驱动部以驱动修边模块200工作。控制模块还用于控制移动模块以使自动割草机沿着第二方向行走工作区域边界时，控制修边驱动部以驱动修边模块200工作和/或控制切割驱动部以驱动切割模块300工作；其中，第二方向为第一方向的反方向。通过修边模块200和切割模块300配合，以更好的修剪工作区域内以及工作区域边缘一带的草等植物。

可选地，切割模块300包括用于切割植物的刚性切割元件。刚性切割元件包括金属切割刀片或石质切割刀片，或者其他材质。刚性切割元件的修剪草等植物的效果优于柔性修剪元件210。
可选地，修边模块200包括柔性修剪元件210，切割模块300包括刚性切割元件。通过包括柔性修剪元件210的修边模块200和包括刚性切割元件的切割模块300配合，以更好的修剪工作区域内以及工作区域边缘一带的草等植物。
在一个实施例中，修边模块200位于中轴线的一侧，这里，位于中轴线一侧并不特指整个修边模块200位于中轴线一侧，而是第二转轴位于中轴线的一侧。自动割草机包括修边模式，在修边模式中，控制模块接收检测模块的检测信号，从而壳体相对于工作区域边界的位置，基于此，控制自动割草机沿着工作区域边界移动，使得第二转轴所在的一侧朝向工作区域外。同时，控制模块控制修边模块工作，使得自动割草机沿着工作区域边界进行修边。
本实施例中，可选的，切割模块300位于中轴线或中轴线的某一侧，在修边模式中，可选的，控制模块控制切割模块300与修边模块同时工作，或控制模块控制切割模块不工作。
本发明的一个实施例提供上述自动割草机的控制方法，包括如下步骤：
检测工作区域边界；
判断是否满足修边启动条件，则控制修边模块200工作，移动模块沿工作区域边界移动，使修边模块200所在的一侧朝向所述工作区域外。
在一个实施例中，自动割草机包括沿边模式和修边模式，在沿边模式中， 控制模块控制切割模块300工作，并控制自动割草机沿工作区域边界移动。在修边模式中，控制模块控制修边模块200工作，并控制自动割草机沿工作区域边界移动。参考图18，本实施例中，修边模块200位于中轴线的一侧在修边模式中，控制模块控制自动割草机沿工作区域边界移动，使得修边模块200所在一侧朝向工作区域外。也就是说，若修边模块200位于中轴线的左侧，在修边模式中，自动割草机沿工作区域边界以顺时针方向移动。若修边模块200位于中轴线的右侧，在修边模式中，自动割草机沿工作区域边界以逆时针方向移动。
本实施例中，可选的，切割模块300位于中轴线或位于中轴线的某一侧，若切割模块300位于中轴线上，在沿边模式中，控制模块控制自动割草机沿边界顺时针移动或逆时针移动皆可。若切割模块300位于修边模块200的同一侧，控制模块控制自动割草机沿边界移动，且移动方向与修边模式相同。若切割模块300位于修边模块200的不同侧，控制模块控制自动割草机沿边界移动，且移动方向与修边模式相反。
本发明的一个实施例提供上述自动割草机的控制方法，包括如下步骤：
判断是否满足沿边启动条件，若满足，则控制切割模块300工作，移动模块沿工作区域边界移动；
判断是否满足修边启动条件，若满足，则控制修边模块200工作，移动模块沿工作区域边界移动，使修边模块200所在的一侧朝向所述工作区域外。
在一个实施例中，沿边启动条件包括控制模块接收到沿边启动信号，工作区域切割完成信号，回归信号等。修边启动条件包括控制模块接收到沿边完成信号，还可以包括修边启动信号，工作区域切割完成信号，回归信号等。可以理解的是，本实施例中，沿边工作在修边工作开始前完成，但不限制沿边工作与修边工作是否连续进行。
继续参考图18，在一个实施例中，修边模块200位于中轴线的一侧，切割模块300位于中轴线的另一侧，在沿边模式中，控制模块控制自动割草机沿工作区域边界移动，使得切割模块300所在的所述另一侧朝向工作区域外。在沿边模式中，控制模块控制切割模块300工作，自动割草机以第一方向沿工作区域边界行走，使得切割模块300所在的一侧朝向工作区域外，因 而切割模块300能够最大限度地切割到工作区域边界。在修边模式中，控制模块控制修边模块200工作，自动割草机以第二方向沿工作区域边界行走，使得修边模块200所在的一侧朝向工作区域外，因而修边模块200能切割到切割模块300无法达到的区域。本实施例中，控制模块控制沿边模式先于修边模式启动。当沿边模式完成后，方可启动修边模式。可选的，在修边模式中，自动割草机沿工作区域边界移动的距离或时间满足预设值，则判断沿边模式完成。可选的，控制模块可以控制自动割草机在沿边模式完成后即进行修边模式，完成自动割草机的修边工作。控制模块也可以控制自动割草机在修边模式完成后进入其他模式，待接收到修边模式启动信号后进入修边模式。
本发明的一个实施例提供上述自动割草机的控制方法，包括如下步骤：
判断是否满足沿边启动条件，若满足，则控制切割模块300工作，移动模块以第一方向沿工作区域边界移动，使切割模块300朝向工作区域外。
判断是否满足修边启动条件，若满足，则控制修边模块200工作，移动模块沿工作区域边界移动，使修边模块200所在的一侧朝向所述工作区域外。以该方向为第二方向。由于切割模块300和修边模块200分别位于中轴线两侧，第一方向和第二方向为相反方向。
在其他所实施例中，参考图5，可选的，若切割模块300位于所述中轴线上，在沿边模式中，控制模块可控制自动割草机沿工作区域边界以顺时针方向移动，或以逆时针方向移动。
在一个实施例中，自动割草机的控制方法，包括如下步骤：
检测是否满足修边启动条件，若满足，则控制切割模块300和修边模块200工作，移动模块沿工作区域边界移动，使修边模块200朝向工作区域外。本实施例中，当移动模块沿工作区域边界移动，切割模块300和修边模块200同时工作。可选的，第一转轴位于中轴线上。
本发明的一个实施例提供一种自动割草机的控制方法，包括如下步骤：
启动沿边模式，自动割草机沿着第一方向行走工作区域边界，修边模块200工作和/或切割模块300工作；可选地，工作区域边界可以为环形、直线形、曲线形、不规则形或者其它形状。
之后，启动修边模式，自动割草机沿着第二方向行走该工作区域边界， 切割模块300工作和/或修边模块200工作；其中，第二方向为第一方向的反方向，也即自动割草机沿着该工作区域边界反方向行走。
也就是说，启动沿边模式后，自动割草机可以沿着第一方向行走工作区域边界，修边模块200工作修剪植物，切割模块300停止工作；之后，启动修边模式，自动割草机沿着第二方向行走该工作区域边界，切割模块300工作修剪切割植物，修边模块200停止工作；
也可以为，启动沿边模式后，自动割草机可以沿着第一方向行走工作区域边界，切割模块300工作修剪切割植物，修边模块200停止工作；之后，启动修边模式，自动割草机沿着第二方向行走该工作区域边界，修边模块200工作修剪植物，切割模块300停止工作。
还可以为，启动沿边模式后，自动割草机可以沿着第一方向行走工作区域边界，修边模块200和切割模块300均工作修剪切割植物；之后，启动修边模式，自动割草机沿着第二方向行走该工作区域边界，修边模块200和切割模块300均工作修剪切割植物。
本发明的一个实施例提供一种自动割草机的控制方法，包括如下步骤：
启动修边模式，自动割草机沿着第二方向行走该工作区域边界，切割模块300工作和/或修边模块200工作；
之后，启动沿边模式，自动割草机沿着第一方向行走工作区域边界，修边模块200工作和/或切割模块300工作；其中，第二方向为第一方向的反方向，也即自动割草机沿着该工作区域边界反方向行走。
可选地，工作区域边界可以为环形、直线形、曲线形、不规则形或者其它形状。
可选地，自动割草机沿着第一方向行走工作区域边界，可以行走全部或者部分工作区域边界，也可以行走一次或者多次工作区域边界；例如工作区域边界为环形时，自动割草机沿着第一方向行走一整圈、多圈或者半圈。
可选地，自动割草机沿着第二方向行走工作区域边界，可以行走全部或者部分工作区域边界，也可以行走一次或者多次工作区域边界；例如工作区域边界为环形时，自动割草机沿着第二方向行走一整圈、多圈或者半圈。
参见图15-图18所示，本实施例的可选方案中，在沿边模式，自动割草机沿着第一方向行走工作区域边界，切割模块300工作，修边模块200停 止工作；如图15和图16，切割模块300工作时，切割模块300未能完全修剪到边。
之后，启动修边模式，自动割草机沿着第二方向行走工作区域边界，修边模块200工作并修剪工作区域边界之外的植物，切割模块300停止工作；如图17和图18，修边模块200工作时，修边模块200可以完全修剪到边。
通过先令包括刚性切割元件的切割模块300进行修剪工作，再令柔性修剪元件210的修边模块200进行修剪工作，以减少柔性修剪元件210的实际切割宽度，使切边效果更好，还减少了柔性修剪元件210的磨损，使柔性修剪元件210更耐用。
针对修边模块200的位置布置，本实施例提供了一组自动割草机行走具有直角转弯的工作区域边界修剪其边缘一带的草等植物示例。参见图12-图14所示，修边模块200分别设置在壳体100靠近机头、靠近机中、靠近机尾三个位置，修边模块200的修剪直径相同。参见图12所示，修边模块200尽可能布置在壳体100前侧，也即靠近机头的位置；参见图13所示，修边模块200尽可能布置在壳体100中间，也即靠近机中的位置；参见图14所示，修边模块200尽可能布置在壳体100后侧，也即靠近机尾的位置。
参见图12-图14所示，修边模块200布置在壳体100不同位置，其转角未切割面积不同；其中，靠近机头的修边模块200未切割面积，小于靠近机中的修边模块200未切割面积；靠近机中的修边模块200未切割面积，小于靠近机尾的修边模块200未切割面积。因此，修边模块200尽可能布置在壳体100前侧，也即靠近机头的位置，转弯时转角未切割面积较小。
结合图15和图17所示，本实施例还提供一种割草系统，包括供电站400和上述的自动割草机；
供电站400用于提供电能给自动割草机。供电站400可以通过有线或者无线的方式供电给自动割草机。
所述割草系统包括上述的自动割草机；上述自动割草机的技术特征也适用于该割草系统，自动割草机已公开的技术特征不再重复描述。所述割草系统具有所述自动割草机的优点，自动割草机所公开的优点在此不再重复描述。
