其中，本发明实施例中提供的自移动设备用以智能化的执行作业任务，将用户从费时费力的繁琐工作中解放出来。该自移动设备可以是智能割草机、智能打草机、智能修枝机，智能扫雪机等自动、半自动的机器。以下实施例中，该自移动设备以智能割草机为例。
在本发明的第一实施例中，该边界识别模块包括位置检测模块，利用位置检测模块识别工作区域的边界。如图3所示，自移动设备以智能割草机100，工作区域以草坪200为例，智能割草机100在一草坪200内执行切割任务的同时，会利用位置检测模块11检测智能割草机100的当前位置，将当前位置与一预设的地图比较来识别草坪的边界201，当检测到当前位置为草坪的边界201时，控制模块30控制智能割草机100转向或后退等，使得智能割草机100不会越出该边界，始终能够在草坪200内行走并工作。其中，该位置检测模块11包括卫星信号获取单元，卫星信号获取单元例如为GPS定位模块，该位置检测模块利用GPS模块获取卫星信号，基于卫星信号来计算智能割草机100的当前位置。
上述实施例中的预设的地图可以是用户预先操作具有位置检测模块11的自移动设备100在边界201行走形成的边界地图，其可以是用户亲自引导自移动设备100在边界行走的方式，也可以是用户遥控自移动设备100在边界行走的方式，或者用户预先操作从自移动设备100上拆卸的位置检测模块11检测边界201以生成的边界地图，当然，也可以是用户预先使用具有位置检测功能的其他定位模块检测边界201生成的边界地图，再将该边界地图传输到自移动设备100，又或者是自移动设备100预先从云端获取的边界地图，当然可实现地，自移动设备也可以不获取地图，而是将当前位置与云端存储的边界地图比较，判断自移动设备100的当前位置与边界地图的位置关系，从而控制其自身在边界限制的工作区域200的移动。总之，该获取该预设的地图的形式并不限定。
在另一个实施例中，上述位置检测模块也可以通过与在工作区域的边界位置设置的多个定位信标通信而获取自移动设备的当前位置，例如，在工作区域的边界位置设有多个定位信标，自移动设备上设置有定位元件，该定位元件能够与定位信标通信，在定位元件跟随自移动设备移动的同时，自移动设备获取自身到该定位信标的距离，最终获取工作区域边界位置的集合，即获取工作区域的边界地图。自移动设备在执行任务过程的同时，会获取自身的当 前位置，判断当前位置与边界地图的位置关系，最终控制自移动设备能够一直在工作区域内行走并工作。本实施例中，定位信标和定位元件采用超宽带标签定位(UWB)技术进行位置计算，即定位元件为超宽带定位元件，或称超宽带定位标签，定位信标为超宽带标签定位模块。在另一个实施例中，定位信标和定位元件采用超声波定位技术进行位置计算，当然，其他的定位方式也是可行的，如红外定位技术、WIFI定位技术、蓝牙定位技术、Zigbee定位技术等方式。
在本发明的第二实施例中，边界识别模块包括表面特征识别模块，表面特征识别模块基于工作区域表面的特征与非工作区域表面特征的不同而识别工作区域的边界。以工作区域内为草坪，工作区域外为马路为例，草坪与马路的表面特征是不同的，而自移动设备的表面特征识别模块能够分辨出两者的不同，从而能够识别出两者的分界。其中，表面特征识别模块可以是图像获取模块、电容检测模块、毫米波雷达检测模块、多光谱检测模块、红外激光图像检测模块的其中一种或多种。本领域技术人员可理解地，图像获取模块通过识别草地的颜色和/或纹理特征等而识别边界。电容检测模块通过识别草地的水分特征而识别边界。毫米波雷达检测模块通过识别草地表面的回波特征而识别边界。多光谱检测模块通过识别草地的叶绿素含量而识别边界，红外激光图像通过来获取草地图像中像素的离散度来识别边界。本发明实施例中的表面特征识别模块只要能够有效识别草地与非草地的区域特征以识别边界即可，种类并不限定。
利用上述各实施例的边界识别模块识别工作区域的边界时，可在边界位置设置磁性装置，以辅助限定工作区域的边界。具体地，磁性装置用于设置在信号不可靠的边界位置，其中，信号不可靠的边界位置包括卫星信号不可靠的边界位置，或工作区域的表面特征和/或非工作区域表面特征不可靠的位置。将磁性装置设置在边界位置，以解决只利用边界识别模块识别边界，由于边界识别模块识别的信号不可靠，造成对边界识别的误判的问题。下面实施例具体介绍。
如图4所示，例如用户家的草坪200内的某一处或几处设置有树木、灌丛，卫星信号获取单元在该处接收到的卫星信号质量较差或者根本无法收到卫星信号，卫星信号获取单元无法接收到可靠的卫星信号的位置我们可以称之为阴影区域，当智能割草机100行走到阴影区域时，无法准确检测自身的当前位置，当该阴影区域位于边界201时，位置检测模块11很容易产生误判，例如，智能割草机200基于位置检测模块11的判定结果，认为该位置位于边界201内，而此时智能割草机100继续行走工作，则会驶出边界201外，智能割草机多次行走到工作区域外，会影响其切割效率，还会存在安全隐患。此时，为了准确检测边界201，在 边界201的阴影区域设置磁性装置300，阴影区域在图4中以斜线填充表示，磁性装置会引起磁场变化，产生磁信号，智能割草机100在草坪200内工作时，除了通过位置检测模块11检测其自身的当前位置，比较当前位置与边界201的位置关系外，还会实时地通过磁信号检测模块20检测磁性装置30产生的磁信号，控制模块300会结合位置检测模块11和磁信号检测模块20的检测结果来判断智能割草机100的当前位置，例如，智能割草机200行走到阴影区域时，控制模块30利用卫星信号获取单元接收的卫星信号不可靠，无法准确反映智能割草机200的当前位置与边界位置的关系，此时，控制模块控制磁信号检测模块20检测到磁性装置30产生的磁信号，当智能割草机200行走到磁性装置30的有效检测范围内，即可基于检测到的磁信号的强度和/或方向计算出智能割草机100的当前位置与边界201位置的距离和方向，以判断智能割草机100的当前位置是否为边界位置，若磁信号检测模块20检测到边界201，则控制模块30即可控制智能割草机100执行转向或后退等动作，以控制智能割草机100远离边界201或者控制智能割草机100沿着边界201切割，以执行沿边界切割的修边模式。可理解的是，该磁性装置30不仅可以设置在信号不可靠的边界附近位置，还可以设置在信号不可靠的其他位置，例如两个工作区域被一空间分离，该空间内卫星信号不可靠，此时在空间内设置磁性装置，以便于引导智能割草机沿着磁性装置从一个区域进入到另一个区域，该实施例会在下文中介绍。
如图5所示的实施例中，工作区域200的边界位置由于斑驳草地，智能割草机100在工作的过程中，利用电容传感器等表面特征识别模块12无法清楚分辨边界201，很容易造成对边界201检测的误判，例如智能割草机100很容易行走到工作区域外部，发生危险，因此，用户可以在工作区域的表面特征和/或非工作区域表面特征不可靠的边界位置设置磁性装置300，也就是说，用户可以在特征不清晰的边界位置设置磁性装置300，该特征不清晰的边界位置在图5中以斜线填充表示，表面特征识别模块12将边界识别结果输出至控制模块，控制模块经过判断后，例如，控制模块判断到表面特征识别模块的识别结果不准确时，控制模块控制磁信号检测模块20检测磁性装置300以辅助检测边界201，即使在表面特征识别模块12检测结果不准确的情况下，还能够利用磁信号检测模块20检测磁性装置限定的边界201，以提高检测边界的准确性。当然，根据需要，表面特征识别模块12和磁信号检测模块20可以同时进行检测，综合两者的检测结果来分析工作区域的边界。
同样，在利用表面特征识别模块识别边界的第二实施例中，磁性装置不仅可以设置在边界附近位置，还可以设置在其他位置，下文会进行介绍。
上述各实施例中，磁性装置300的设置位置基于预设的地图生成，也就是说，该预设的 地图上显示可以设置磁性装置的位置，例如，在由GPS等位置检测模块检测边界，生成预设地图时，该预设地图上会显示卫星信号不可靠的位置，在卫星信号不可靠的位置会生成可以设置磁性装置的提示，用户根据需要在提示的位置设置磁性装置，可理解的，当预设的地图是由自移动设备从外部获取时，该预设的地图上也可以显示设置磁性装置设置位置的提示。
如图6所示，本发明实施例中的自动工作系统还包括供自移动设备停靠的停靠站400，以供自移动设备100停靠在停靠站400上待机或充电，若停靠站附近由于灌木等原因，造成卫星信号不可靠，形成阴影区域(在图6中以斜线填充表示)，自移动设备100无法准确检测自己的位置，导致无法顺利回归停靠站400，则在停靠站400位置处设置磁性装置300，利用磁信号检测装置检测磁性装置300，以引导自移动设备100回归到停靠站400，具体地，磁性装置设置在指示自移动设备与停靠站对接的方向上，即磁性装置在水平方向上的延伸方向与自移动设备的行走方向平行，距离停靠站越近，磁场信号越强烈。自移动设备利用GPS、视觉等技术回归到停靠站附近时，磁信号检测模块会检测到磁性装置300的磁信号时，并将检测到的磁信号传输给控制模块，控制模块基于磁场信号的强度和/或方向判断出自移动设备距离停靠站的距离和/方向，控制自移动设备100沿着磁性装置300向停靠站400靠近，最终引导自移动设备100回归到停靠站400处。其中，停靠站附近具体可以指以停靠站为圆心小于1.5米范围内的环境。
再如图6所示，磁性装置300设置在停靠站400的延伸位置，磁性装置300的一端与停靠站400的一端连接或者十分接近，在自移动设备100的回归过程中，磁信号检测模块检测周围环境的磁信号，当磁信号检测模块检测到磁性装置产生的磁信号时，控制模块基于磁信号的强度和/或方向控制自移动设备100沿着磁性装置300移动，以引导自移动设备100回归到停靠站400上，如有必要地，再利用停靠站400上的导轨等对接技术引导自移动设备100准确停靠在停靠站上的对接位置。
如图7-8所示，至少部分磁性装置300还可以设置在停靠站400上，具体地，磁性装置400可以设置在停靠站的底座401的中轴线402上。当自移动设备100回归到停靠站400附近时，磁信号检测模块检测到磁性装置的磁信号，并且在磁性装置的作用下沿着磁性装置300不断向停靠站的对接位置靠近，理想地，自移动设备100的中轴线101会与磁性装置300不断靠近并最终重合，并实现自移动设备100与停靠站400的准确对接。
上述在停靠站处设置磁性装置的方案也同样适用于本发明利用表面特征识别模块识别工作区域的边界的第二实施例，利用磁性装置辅助引导自移动设备回归到停靠站。
请再参阅图8所示，本实施例中，地磁检测模块的数量为2个，磁信号检测模块20包括 第一地磁检测模块2011和第二地磁检测模块2012，第一地磁检测模块2011和第二地磁检测模块2012分别安装于自移动设备100前进方向的两侧，具体地，可以对称设置在自移动设备前进方向的两侧，并分别用于检测磁性装置300产生的第一磁信号和第二磁信号，当自移动设备200靠近停靠站400的过程中，第一地磁检测模块2011和第二地磁检测模块2012实时检测第一磁信号和第二磁信号并实时调整机器的行走方向，当调整到检测到的第一磁信号和第二磁信号的方向相反时，表示自移动设备100的两个地磁检测模块位于磁性装置的两侧，具体的，假设第一地磁检测传感模块2011设置于自移动设备行走方向上的前侧靠右位置，第二地磁检测模块2012设置于自移动设备行走方向上的前侧靠左位置，则当第一磁场信号的强度大于第二磁场信号的强度时，控制模块300可以控制自移动设备100向左调整位置；当第一磁场信号的强度小于第二磁场信号的强度时，控制模块300可以控制自移动设备100向右调整位置；当第一磁场信号的强度与第二磁场信号的强度相等时，控制模块300可以控制自移动设备100直行。当自移动设备100到达到对接位置时，例如当磁信号强度到达预设强度时，控制自移动设备停止。可理解的是，自移动设备100会行走的较为缓慢且转动幅度较小，以随时做出纠正动作。本实施例通过在自移动设备上设置两个对称的地磁检测传感模块，检测灵敏度高，更方便准确地判定出自移动设备相对于停靠站的距离和方位，从而实现自移动设备的精确回归以及自动充电。
如图9所示，自移动设备的工作区域通常是不连续的，例如用户家的前院和后院是分离的，通常通过一通道相连，以前院为第一工作区域202，后院为第二工作区域203为例，该第一工作区域202和第二工作区域203被一空间500分离，当自移动设备在第一工作区域202完成工作任务需要进入到第二工作区域203执行任务，或者自移动设备在第一工作区域202工作时电量不足需要回归到第二工作区域203的停靠站进行充电等情况时，自移动设备100需要从第一工作区域202进入到第二工作区域203时，此时为了方便引导自移动设备100从第一工作区域202进入到第二工作区域203，可以在该空间500内设置磁性装置300，尤其设置在第一工作区域边界的附近位置，该磁性装置300的设置方向指示能够穿越空间500从第一工作区域202进入到第二工作区域203的方向上，当自移动设备100需要穿越该空间500时，自移动设备100可以沿着第一工作区域202的边界行走，以检测空间500内的磁性装置300，当检测到磁性装置300的磁信号时，控制模块30基于磁信号的强度和/或方向控制自移动设备100沿着磁性装置300移动，以穿越该空间500从第一工作区域202进入第二工作区域203。其中，自移动设备以沿着第一工作区域边界移动的路线来检测磁性装置，使得自移动设备有规律且快速的检测到磁性装置，防止自移动设备在工作区域内盲目地行走检测，影 响检测到磁性装置的效率。
上述实施例中，磁性装置优选设置在空间内信号不可靠的位置，例如在利用位置检测模块，如利用GPS模块检测自移动设备的位置时，若该空间内由于灌木等原因，导致该空间内的卫星信号质量不可靠，此时，自移动设备无法基于卫星信号而得到自己的位置，也就无法穿越该空间，此时，在该空间内设置磁性装置，当自移动设备检测到磁性装置时沿着磁性装置行走，能够准确引导自移动设备穿越该空间。可理解的是，该实施例也同样适用于利用表面特征识别模块识别边界的情况，例如连接第一工作区域和第二工作区域的该空间一般为通道，该通道通常为为了方便用户行走而铺设的石板路等没有杂草的路面，而智能割草机的表面特征识别模块识别到该通道为非工作区域，此时智能割草机会远离该通道，也就无法穿越该通道，此时在该通道内设置一起引导作用的磁性装置，当智能割草机需要从第一工作区域进入到第二工作区域时，利用磁信号检测模块检测磁性装置，并沿着磁性装置移动，最终穿越该空间进入到第二工作区域。
在一个具体的实施例中，磁性装置还可以设置在工作区域内的排除区域，起到禁止自移动设备进入到排除区域的作用。如图10所示，用户家的草坪200内包括一花坛204，草坪200是需要智能割草机执行任务的工作区域，而该花坛204是不需要智能割草机执行切割任务的区域的排除区域，排除区域定义为工作区域内禁止自移动设备执行工作任务的区域，此时，用户可以在排除区域，即在花坛204的周围设置磁性装置，起到隔离墙的作用，当智能割草机在草坪内执行切割任务时，还会同时利用磁性检测装置检测磁性装置，控制模块根据检测到的磁信号的强度和/或方向判断智能割草机与花坛204的距离和/或方向，当接近花坛204时，控制模块控制智能割草机后退或转向以远离到花坛204，防止智能割草机进入到花坛204切割，对花坛204造成伤害，或者控制智能割草机沿着花坛边界行走切割，以将花坛204周边的杂草切割干净。
可理解的是，本发明上述各实施例中的自移动设备的控制模块会判断边界识别模块的识别结果可靠度，例如边界识别模块为GPS模块时，控制模块分析GPS模块接收卫星信号的可靠度，当可靠度在一预设范围时，控制模块判断此时卫星信号可靠性高，则控制模块以GPS模块检测边界的结果为边界识别的结果，相应地，此时控制模块不采用磁信号检测模块检测边界的结果，而当控制模块分析到GPS模块接收的卫星信号可靠度超过预设范围时，此时表示卫星信号可靠性差，利用GPS模块识别的边界误差性大，此时，控制模块以磁信号检测模块检测的边界结果为准来控制自移动设备的移动方式，忽略GPS模块的检测结果。如此设置是为了防止在由于卫星信号不可靠时，GPS模块检测结果不可靠，而自移动设备以不可靠的 检测结果为准造成误判，影响工作效率，还有可能造成对自移动设备或工作区域的损坏。
在另一实施例中，若自移动设备不设置边界识别模块的识别结果可靠度，还可以采用以下方案，即若当磁信号检测模块的检测结果与边界识别模块的识别结果不同时，控制模块基于磁信号检测模块的检测结果控制自移动设备的移动方式。举例说明，当利用GPS模块检测到某一位置为非边界区域，而磁信号检测模块检测到该位置的磁信号，判断该位置为边界，则控制模块以磁信号检测模块的检测结果为准，判断该位置为边界，控制自移动设备的移动。
本发明实施例还提出了一种自动工作系统的工作方法，该自动工作系统包括上述各实施例中介绍的在边界限定的工作区域内移动并执行工作任务的自移动设备，用于设置在工作区域内或工作区域边界附近位置的磁性装置，该自移动设备包括边界识别模块、磁信号检测模块及控制模块，该控制方法包括以下步骤：
步骤S1：识别工作区域的边界；
步骤S2：检测磁性装置以进一步识别工作区域的边界和/或引导自移动设备；
步骤S3：基于边界识别模块的识别结果和/或磁信号检测模块的检测结果控制自移动设备的移动方式。
本发明实施例还提出了一种自移动设备，该自移动设备包括边界识别模块、磁信号检测模块及控制模块，边界识别模块用于识别工作区域的边界，控制模块控制自移动设备在边界限制的工作区域内移动并执行工作任务；磁信号检测模块检测磁信号以进一步识别工作区域的边界和/或引导自移动设备；控制模块基于边界识别模块的识别结果和/或磁信号检测模块的检测结果控制自移动设备的移动方式。可理解的是，该磁信号由用于设置在工作区域内或工作区域边界附近位置的磁性装置产生。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
