另外,为了更好的说明本公开,在下文的具体实施方式中给出了众多的具体细节。本领域技术人员应当理解,没有某些具体细节,本公开同样可以实施。在一些实例中,对于本领域技术人员熟知的方法、手段、元件和电路未作详细描述,以便于凸显本公开的主旨。
图1示出根据本公开实施例的一种自移动设备的模块图,其中本公开实施例提供的自移动设备可以是能够自动行进的设备,其可以包括任意的智能 机器人,例如智能扫地机、智能扫雪机、智能割草机、智能洒水机、智能摄像机器人等,只要能够自动行走即可以作为本公开实施例的自移动设备。
本公开实施例可以为自动移动设备配置无线充电站,该无线充电站可以用于为自动设备充电,即为自动设备提供电力。自移动设备可以根据设备的类型在工作区域内移动工作,在满足充电条件时即会向无线充电站移动,以通过无线充电站执行充电操作。
如图1所示,本公开实施例的自移动设备100可以包括:
无线充电接收模块101,其配置为基于从无线充电站上的无线充电发射模块接收的无线充电信号执行充电操作;
回归引导模块102,其配置为检测用于引导自移动设备向无线充电站移动的引导信息;
到位感测模块103,其配置为感测到位引导装置;
第一控制模块104,其配置为根据检测到的引导信息控制自移动设备向无线充电站移动,并配置为在感测到到位引导装置时,调节自移动设备的运行参数,运行参数包括:运行速度和/或运行方向。
其中,为自移动设备执行充电操作的无线充电站中可以包括到位引导装置,自移动设备在向无线充电站移动的过程中可以通过感测该到位引导装置确定无线充电站的位置。图2示出根据本公开实施例自移动设备与无线充电站对接时的示意图。其中,无线充电站200的充电底板203上可以包括到位引导装置201和无线充电发射模块202,其中,无线充电发射模块202用于发射无线充电信号,自移动设备在移动到无线充电站的充电区域时,可以通过无线充电发射模块发射的无线充电信号进行充电操作。
如上述实施例所述,自移动设备可以通过回归引导模块102检测引导其向无线充电站200移动的引导信息,通过该引导信息可以确定无线充电站的位置,从而实现自主移动设备移动至无线充电站的引导回归。同时自移动设 备还可以通过到位感测模块103感测到位引导装置201确定即将到达或者已经到达无线充电站200,从而执行运行参数的调节。
在一种可能的实施方式中,自移动设备可以根据剩余电量的情况确定是否满足充电条件,在满足充电条件时,控制回归引导模块检测引导信息。图3示出根据本公开实施例的自移动设备的另一模块图。如图3所示,其中相较于图1的实施例,本公开实施例中的自移动设备还可以包括检测模块105和电源模块106,其中检测模块105可以用于检测自移动设备是否满足充电条件。电源模块106用于为自移动设备的工作提供电量,其可以与无线充电接收模块101连接,以通过无线充电接收模块101接收的无线充电信号执行电源模块106的充电操作。其中,检测模块105可以与电源模块106连接,用于获取电源模块106当前的剩余电量值,并可以根据检测到的剩余电量值确定是否满足充电条件,例如,可以确定剩余电量值是否超过参考电量,如超过参考电量,则不满足充电条件,如未超过参考电量,则满足充电条件。其中,参考电量可以根据电源模块的电池容量以及充电需求设定,具体数值本公开实施例不进行限定。或者,检测模块105也可以根据剩余电量与电源容量之间的比值确定是否满足充电条件,其中在该比值大于参考比值时,判断为不满足充电条件,在该比值小于参考比值时,判断为满足充电条件,同样该参考比值也可以根据设备的电源容量以及充电需求设定,例如可以设为10%等,本公开不进行具体限定。
在另一种可能的实施方式中,检测模块105也可以根据接收到的充电指令判断为满足充电条件。如图3所示,自移动设备还可以包括第一通信模块107,该第一通信模块107可以执行与其他设备之间的通信。例如,第一通信模块107可以包括蓝牙单元、wifi单元或者其他通信单元,只要能够执行通信操作即可以作为本公开实施例中的第一通信模块107。第一通信模块107可以接收其他设备(如控制器)传输的充电控制指令,并将该充电控制指令传输 给检测模块105,在检测模块接收到充电控制指令时即可以判断为自移动设备满足充电条件。另外,检测模块106也可以检测用户输入的指令信息,例如自移动设备上可以设置有输入模块108,该输入模块可以包括触控屏、键盘、语音输入模块等输入接口,用户可以通过输入模块输入控制指令,例如充电控制指令、开机指令、关机指令等用于控制自移动设备的指令。检测模块106可以与输入模块108连接,接收输入模块108传输的充电控制指令,在接收到该充电控制指令时,即可以判断为满足充电条件。
以上仅为示例性的说明满足充电条件的情况,在本公开的其他实施例中,可以通过其他方式判断是否满足充电条件,本公开对此不进行具体限定,只要能够对充电条件进行判断,即可以作为本公开实施例。
在检测出满足充电条件时,第一控制模块104即可以通过回归引导模块102检测引导信息。本公开实施例的回归引导模块104可以通过检测自移动设备的工作区域边界信息确定引导信息,或者也可以通过获得的无线充电站的第二位置信息确定引导信息。
图4示出根据本公开实施例的自移动设备的回归无线充电站的示意图。其中,在自移动设备的工作区域的边界处围设有产生边界信息的引导线109,该引导线109可以与无线充电站200电连接,由于无线充电站200可以向引导线109供电,因此在引导线109中传输有电力,基于引导线传输的电力信号可以产生引导信息,例如,基于引导线中传输的电力可以在引导线周围产生电磁场,引导信息可以是电磁场的磁力信号,进而回归引导模块102可以检测该磁力信号作为引导信息,第一控制模块104可以接收回归引导模块102检测的引导信息,并根据该检测到的引导信息控制自移动设备沿引导线向无线充电站200移动。在一种可能的实施方式中,回归引导模块102可以包括设置在自移动设备的充电底座203两侧的两个第一检测单元,两个第一检测单元可以分别检测作为引导信息的磁力信号,第一检测单元可以包括磁力传感器。 其中,在自移动设备在工作区域未到达引导线109的位置时,第一控制模块104可以根据两个第一检测单元检测到的磁力信号的强度确定引导线的位置,由于距离引导线越近的位置磁力信号的强度越强,因此可以根据第一检测单元检测到的磁力信号的强度控制自移动设备向引导线移动。
当自移动设备移动至引导线的位置处,此时第一控制单元可以根据两个第一检测单元检测到的磁力信号的强度来控制自移动设备沿引导线移动至无线充电站。同样的,在沿引导线移动的过程中,第一控制模块104可以控制自移动设备沿两个第一检测单元检测到的磁力信号强度相同并且实时采集的磁力信号的强度也相同的方向移动,从而可以沿引导线移动至无线充电站。
或者,在本公开的另种实施例方式中,回归引导模块102可以根据磁力信号的相位作为引导信息,第一控制模块也可以根据两个第一检测单元检测到的磁力信号的相位控制自移动设备沿引导线移动,其中第一检测单元可以分别检测磁力信号的相位值,并且,在两个第一检测单元检测的磁力信号的相位值一致时,表明两个第一检测单元对称的位于引导线的两侧,此时第一控制模块可以控制自移动设备沿着两个第一检测单元检测到的磁力信号相位一致的方向移动。
在另外一种实施例中,第一控制模块104可以根据两个第一检测单元检测的磁力信号强度控制自移动设备移动到引导线的位置,再根据两个第一检测单元检测到的磁力信号的相位控制自移动设备沿着两个第一检测单元检测到的磁力信号相位一致的方向移动,这种方式能够控制自移动设备跨引导线回归,左右摆幅能够做到±20mm以内,最终移动到无线充电站的位置,与无线充电站对接。
根据本公开实施例,第一控制模块104可以控制自移动设备沿引导线109移动至无线充电站200,同时到位感测模块103可以感测无线充电站200中的 到位引导装置201,该到位引导装置201可以设置在无线充电发射模块202的附近,或者构造为无线充电发射模块202,从而在感测到到位引导装置201时,第一控制模块104执行自移动设备的降速或者停止运行的控制。
在本公开的另一种实施例中,也可以不设置上述引导线,回归引导模块102还可以用于检测自移动设备是否在工作区域的边界,从而第一控制模块可以控制自移动设备沿该工作区域的边界移动。即回归引导模块102还可以根据检测到的草地信息作为引导信息。其中,回归引导模块102可以包括分别设置在自移动设备的底座两侧的两个第二检测单元,该两个第二检测单元可以用于检测草地信息从而判断是否为工作区域边界信息,例如,第二检测单元可以包括摄像头和图像识别单元,从摄像头获取的图像可以传输至图像识别单元。图像识别单元可以识别获得的图像中是否包括草地,并将识别结果传输给第一控制模块。其中,第一控制模块可以在一个第二检测单元识别出草地且另一个第二检测单元的图像中不包括草地时,判断出自移动设备的位置为工作区域的边界,此时可以控制自移动设备沿着两个第二检测单元中的一个检测单元检测到的草地而另一个检测单元检测不到草地的方向移动,从而可以根据工作区域的边界移动至无线充电站。
或者,本公开实施例的第二检测单元也可以为电容传感器,由于电容传感器可以与草地接触,从而检测到草地的电容值,第一控制模块104可以根据两个第二检测单元所检测到的电容值确定自移动设备是否在工作区域,或者是否在工作区域的边界。其中,如果两个检测单元检测到的电容值相同,且为预存储的电容值,则表明自移动设备在工作区域内,如果两个检测单元检测到的电容值相同,且不是预存储的电容值,说明自移动设备移动到工作区域外部,此时第一控制模块可以控制自移动设备调整运行方向移动至工作区域内,另外,如果两个第二检测单元中一个第二检测单元检测到的电容值为预存储的电容值,另一个第二检测单元检测到的电容值不是预存储的电容 值时,此时可以确定自移动设备位于工作区域的边界,此时第一控制模块104可以控制自移动设备沿工作区域的边界移动。
在另一种可能的实施方式中,回归引导模块可以检测自移动设备的第一位置信息,如回归引导模块还可以包括GPS定位单元,用于获取自移动设备的位置。并且在自移动设备中还可以存储有无线充电站的第二位置信息,或者无线充电站也可以向外部发送其第二位置信息,自移动设备可以接收该第二位置信息。对应的,第二控制模块可以根据回归引导模块检测到的自移动设备的第一位置信息,以及自移动设备内存储的无线充电站的第二位置信息,引导自移动设备向无线充电站移动。其中,第二控制模块可以将第一位置信息和第二位置信息之间的差值作为引导信息,并根据该差值调节自移动设备的运行方向,并向无线充电站移动。
根据本公开实施例,可以实现通过回归引导模块102获取的引导信息,控制自移动设备向无线充电站移动。上述实施例仅为回归引导模块示例性说明,在本公开的其他实施例中,回归引导模块也可以通过其他方式获得引导信息,从而第一控制模块根据该引导信息控制自移动设备向无线充电站移动。
自移动设备在朝向无线充电站移动时,可以感测无线充电站设置的到位引导装置,在感测到该到位感测装置时可以降低自移动设备的运行速度,或者控制自移动设备停止运动。下面对到位引导装置进行详细说明。
图5示出根据本公开实施例中的无线充电站的到位引导装置的结构示意图。其中,在一种可能的实施方式中,到位引导装置201可以设置在无线充电站的充电底座203中并且到位引导装置201可以包括磁体组件,并且对应的,自移动设备100中的到位感测模块103可以包括磁性检测元件,该磁性检测元件可以检测磁体的磁场信号,并将磁场信号的参数值传输给第一控制模块104,其中,磁场信号的参数值可以包括磁场的磁力值,即磁场信号的磁 场强度。其中磁性检测元件可以包括磁体传感器或者其他能够检测磁体的磁力的器件,本公开实施例对此不进行限制。第一控制模块104可以接收磁性检测元件传输的磁场信号的参数值,并在磁性检测元件检测磁场信号的参数值符合第一预设条件时,确定为自移动设备到达到位引导装置201,此时可以调节自移动设备的运行参数。
其中,无线充电发射模块202、到位引导装置201均设置在充电底座203中,并且到位引导装置201还可以设置在充电底座的底部,从而避免对于自移动设备的移动的影响。另外,充电底座203与自移动设备执行充电操作的一面上可以与地面平齐的安装,或者嵌入至地面内,不需要突出与地面,从而可以进一步避免对自移动设备的影响。
另外,第一控制模块104在确定接收到的磁场信号的磁场强度大于或者等于参考强度值时,确定为磁场信号满足第一预设条件。也可以是根据磁场强度的关系满足参考强度关系,确定为磁场信号满足第一预设条件,该参考强度值或参考强度关系可以根据设置的磁体组件的磁性、数量、排布方式确定,本公开实施例可以根据需求以及上述变量设定不同的参考强度值或参考强度关系,即本公开实施例对此不进行具体限定,只要该强度值或强度关系能够表明自移动设备移动至到位引导装置的位置处,即可以作为本公开实施例。
另外,本公开实施例中,构造成充电底座203中的到位引导装置201的磁体组件包括条状磁体组件,该条状磁体组件可以包括至少一个磁条或者由磁性物体排列成的条状磁体组件,且该至少一个磁条或者磁性物体可以依次安装在充电底座203上。例如沿水平方向依次排列,或者也可以沿垂直方向排列,本公开对此不进行限定。
基于上述配置,在自移动设备移动中的到位感测模块103感测到到位引导装置201时,即表明自移动设备移动到无线充电站200的位置处,此时第一 控制模块104可以控制自移动设备降低运行速度或控制自移动设备停止运行。
如图5所示的其中一种实施例中,在条状磁体组件中磁条或者磁性物体的安装方向与自移动设备运行方向垂直时,该条状磁体组件至少包括两组,如第一组条状磁体组件和第二组条状磁体组件,并且,自移动设备先经过第一组条状磁体组件。对应的,第一控制模块104可以在磁性检测元件检测到第一组条状磁体组件的磁场信号强度达到第一预设阈值时控制自移动设备降低运行速度,在检测到第二组条状磁体组件的磁场信号强度符合第二预设阈值时控制自移动设备停止运行。其中,第一预设阈值和第二预设阈值可以根据各组的磁体组件的设置数量以及无线充电发射模块202的位置确定,本公开对此不进行限定。也就是说,本公开实施例可以根据设置的磁体组件的磁场信号强度的变化,精确的定位到无线充电站的无线充电发射模块202。
在另外一种实施例中,当条状磁体组件的数量包括多组时,例如第三个磁条为停机的位置,当自移动设备行走越过了第三个磁条时,还可以后退,重新检测条状磁体组件,重新对接。
在另外一种实施例中,当条状磁体组件的数量为一组时,则检测到磁场信号时降低运行速度,磁场强度符合一定值时,自移动设备停止运行。
另外,如图6所示,条状磁体组件201的安装方向也可以与自移动设备运行方向平行,此时第一控制模块104可以在磁性检测元件检测的磁场信号强度符合第三预设阈值时控制自移动设备降低运行速度,检测到磁场信号强度符合第四预设阈值时控制自移动设备停止运行。同样的,第三预设阈值和第四预设阈值可以根据各组的磁体组件的设置数量以及无线充电发射模块202的位置确定,本公开对此不进行限定。也就是说,本公开实施例可以根据设置的磁体组件的磁场信号强度的变化,精确的定位到无线充电站的无线充电发射模块202。同样,本公开实施例可以根据设置的磁体组件的磁场信号强 度的变化,精确的定位到无线充电站的无线充电发射模块202。
在本公开的另一些实施例中,到位引导装置201还可以包括无线信号发射组件,以及到位感测模块103可以包括无线信号接收组件,或者到位引导装置201可以包括无线信号接收组件,以及到位感测模块103可以包括无线发射组件。其中无线信号发射组件可以发射无线信号,同时无线信号接收组件可以接收无线信号发射组件发射的发现信号,并且本公开实施例中无线信号可以在预设距离内传输。其中,无线信号发射组件可以包括RFID(射频)发射器,对应的无线信号接收组件包括RFID阅读器。
在一种可能的实施方式中,到位引导装置201为RFID发射器,到位感测模块103为RFID阅读器,RFID阅读器检测到RFID发射器发射的射频信号时向第一控制模块发送第一信号,表明检测到到位引导装置。对应的第一控制模块在接收到第一信号时执行自移动设备的降速调节或者控制自移动设备停止运行。
在另一种可能的实施方式中,到位引导装置201可以为RFID阅读器,到位感测模块103可以为RFID发射器,无线充电站和自移动设备之间还包括传输信号的通信模块,RFID阅读器检测到RFID发射器发射的射频信号,且自移动设备接收到无线充电站传输的通信信号时,第一控制模块104可以确定为检测到到位引导装置,此时执行自移动设备的降速调节或者控制自移动设备停止运行。
另外,在本公开的另外一些实施例中,无线充电站200的到位引导装置201可以包括无线充电发射模块202,即无线充电发射模块202即可以作为提供充电电力,也可以用于定位感应体。由于无线充电发射模块202中包括充电线圈,则对应的到位感测模块103可以包括线圈感应模块,以用于感测充电线圈。由于充电线圈的磁场的影响,靠近充电线圈的金属、线圈、磁体等器件的等效阻抗会放生变化,此时可以根据该等效阻抗的变化确定检测到到 位引导装置201。使用无线充电发射模块作为到位引导装置,不仅增加了检测系统的可靠性,还降低了成本。
图7示出根据本公开实施例中自移动设备的线圈感应模块检测无线充电发射模块的示意图。如图7所示,线圈感应模块103由PCB板载线圈、电容和Inductance to Digital Converter(简称“检测IC”)组成,通过线圈感应模块103能够检测无线充电发射模块202,即检测到到位引导装置201。图8示出根据本公开实施例中自移动设备的线圈感应模块检测无线充电发射模块的另一示意图。如图8所示,本公开实施例中的自移动设备100中的线圈感应模块103可以为金属探测模块103,金属探测模块103可以在在接近包括无线充电发射模块的到位引导装置201中的线圈等器件时产生阻抗的变化,因此,第一控制模块104可以根据金属探测模块103的输出等效阻抗确定是否检测出无线充电发射模块202。其中,第一控制模块104与金属探测模块103连接以获取金属探测模块输出的等效阻抗,在金属探测模块103输出的等效阻抗变化至预设范围时,确定为检测到无线充电发射模块202。其中,预设范围可以表明此时金属探测模块103与无线充电发射模块202的距离达到距离要求,此时可以确定为检测出到位引导装置,因此对于预设范围的取值本公开实施例不进行限定,具体可以根据不同的需求设定。
图9示出自移动设备与无线充电站回归对接过程的示意图。图10为图9另一方向的示意图。如图9-10所示,在本公开实施例中,当金属探测模块103在无线充电发射模块202的正上方时,金属探测模块103输出的等效阻抗最小,且当金属探测模块103输出的等效阻抗处于某一预设范围内时(事先予以检测设定),就可确定当金属探测模块103在无线充电发射模块202的上方。此时第一控制模块104可以控制自移动设备100减速行走一段时间就可确保自移动设备100上的无线充电接收模块101处于无线充电发射模块发送模块202的正上方,便可待机充电了。
另外,本公开实施例中的线圈感应模块103也可以包括LC振荡器,并且第一控制模块104可以与LC振荡器连接以获取LC振荡器的等效阻抗。并且第一控制模块104可以在LC振荡器输出的等效阻抗变化至预设范围时,确定为检测到到位引导装置。其中,预设范围可以表明此时LC振荡器与无线充电发射模块201的距离满足距离要求,此时可以确定为检测出到位引导装置,因此对于预设范围的取值本公开实施例不进行限定,具体可以根据不同的需求设定。
本公开实施例中的,LC振荡器可以包括一下结构中的至少一种:
图11示出根据本公开实施例中的LC振荡器的组成结构示意图,其中如图9所示,LC振荡器可以包括分别并联连接的第一电感L1、第一电容C1、第一电阻R1和第一振荡器LC1。

基于上述LC振荡器可以实现通过检测LC振荡器输出的等效阻抗的变化来判断LC振荡器是否接近无线充电发射模块202,本公开实施例中,可以在距离无线充电发射模块202越近时,LC振荡器的输出的等效阻抗越小,并且 在LC振荡器位于无线充电发射模块202的正上方时等效阻抗最小。
或者,在本公开实施例中,到位感测模块103也可以是线圈组件,该线圈组件可以根据无线充电发射模块202发射的信号而产生阻抗变化,第一控制模块可以根据该阻抗变化至预设范围时,判断出感测到到位引导装置201。

另外,到位组件2022可以包括与自移动设备100之间相互感应的传感器组件或使自移动设备100运动状态发生突变的机械结构组件。其中,传感器组件可以包括上述实施例中的无线信号发射器/接收器,例如为RFID发射器/接收器、磁性组件,例如磁条或磁钢等,到位组件检测单元基于检测到的信号控制自移动设备停止运行。机械结构组件可以是突出或凹陷于充电底座203上的结构,并可以在自移动设备移动到充电底座上时使得自移动设备停 止运动,并且此时,自移动设备的无线充电接收模块可以位于无线充电发射模块的正上方。到位组件检测单元可以检测磁力信号,第一控制模块可以在磁力信号确满足第一预设条件时控制自移动设备停止运行。

也就是说,本公开实施例可以将无线充电站200的无线充电发射模块202设置在环形组件中,到位感测模块103可以感测该环形组件并且第一控制模块可以根据到位感测模块103感测到的信息控制移动至无线充电发射模块202进行充电。

另外,本公开实施例中外环组件2013和内环组件2014上可以传输有不同的信号,例如,外环组件2013和内环组件2014都可以构造为线圈,并且均可与信号发生器连接,并接收不同的信号,从而使得外环组件2013和内环组件2014可以传输不同的信号参数,例如为种类不同的两种电信号或者频率不同的同种电信号。因此,到位感测模块的内环组件检测单元可以在检测到与内环组件相匹配的磁力信号时,向第一控制模块发送第二信号,此时第一控制模块可以控制自移动设备减速运行或者停止运行。可以理解的是,内环组件检测单元也可以包括两个内环组件检测单元,根据两个内环组件检测单元检测的信号的强度和/或相位进一步调整自移动设备的姿态,使其向着无线充电发射模块202的圆心运动。
另外,内环组件2014也可以包括磁条,相应的内环组件检测单元也可以包括磁性检测单元,从而在该磁性检测单元在检测到与磁条相匹配磁力值时,向第一控制模块发送第二信号,此时第二控制模块可以控制自移动设备减速运行或者停止运行。
基于本公开实施例的上述配置,可以通过多种方式实现自移动设备向无线充电站的移动,且通过感测到位引导装置进一步精确无线充电发射模块的定位,方便的实现自移动设备的充电。
另外,本公开实施例中,第一控制模块104还可以在自移动设备100进入预定充电位置对应的覆盖范围时,控制无线充电接收模块接收无线充电站发送的无线充电信号,即可以执行充电操作。其中,在自移动设备100向无线充电站移动的过程中,可以确定自移动设备是否进入到预定充电位置对应的 覆盖范围,其中通过可以通过下述方式中的至少一种确定自移动设备进入到预设充电位置对应的覆盖范围:

在本公开的另一些实施例中也可以根据其他的方式确定自移动设备是 否进入预定充电位置对应的覆盖范围,例如,自移动设备可以在通过到位感测模块103感测到无线充电站中的到位引导模块201时,确定为进入预定充电位置对应的覆盖范围。即只要能够确定自移动设备进入预定充电位置的覆盖范围则可以作为本公开实施例。

另外,本公开实施例中,自移动设备还包括检测模块105(如图3所示),在充电过程中,检测模块检测对自移动设备的充电是否完成,如果充电已完成,则控制无线充电站进入低功耗模式。检测模块105可以和自移动设备的电源模块106电连接,以检测电源模块的电量,在电源模块的电量符合预定的电量时,例如达到电源的总容量值时,及确定对自移动设备的充电完成。此时第一控制模块可以通过第一通信模块向无线充电站发送充电完成消息,无线充电站的第二通信模块接收到该充电完成消息后,第二控制模块控制无线充电站进入低功耗状态。可理解地,在低功耗状态下,无线充电站只保持无线通信功能。
基于上述配置,可以实现在自移动设备移动至预定充电位置对应的覆盖范围的情况下,执行无线充电接收设备的启动,从而利用无线充电站执行充电操作。
