为了更清楚地说明本公开实施例的技术方案,下面将对实施例描述中所需要使用的附图作简单地介绍,显而易见地,对于本领域普通技术人员而言,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。

图4为根据本公开一实施例提供的不集尘指令的示意图。
详述
为使本公开的目的、技术方案和优点更加清楚,下面将结合本公开实施例的附图,对本公开实施例中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公开的一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例,都属于本公开保护的范围。
在后续的描述中,使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本公开的说明,其本身并没有特定的意义。因此,“模块”与“部件”可以混合地使用。
相关技术中,针对清洁机器人与基站之间需要数据通信的问题,通常采用的是无线传输方式,即分别在清洁机器人、基站上安装无线收发模块,如Sub 1G的433Mhz、蓝牙以及WiFi等,实现“点对点”全双工数据传输。
根据本公开实施例的一方面,提供了清洁系统,如图1所示,该系统包括:清洁机100及与清洁机100对接的基站200,清洁机100与基站200对接形成物理通信链路300。
本公开实施例中,清洁机可以是扫地机、拖地机以及扫拖一体机等。基站是提供给清洁机进行充电、补水、垃圾回收以及停靠待机等功能的站点。清洁机与基站对接可以通过红外信号对接,如基站上设置红外发射装置向外发出红外光束,清洁机上设置红外接收装置因而根据接收到的红外信号找到对准位置,进而进入到对准位置完成与基站的对接。此外,还可以通过激光对接,如基站上设置激光发射装置向外发出激光光束,清洁机上设置激光接收装置因而根据接收到的激光信号找到该对准位置。清洁机和基站上分别可以设置用于对接的电触点或信号触点,以形成上述的物理通信链路,例如,清洁机上设置有充电触点,基站上设置有供电触点,对接完成时,充电触点与供电触点接触而电连接,形成充电回路,据此基站可以向清洁机充电。由于充电触点和供电触点电连接而在充电回路中可以进行电信号传输,因此该充电回路还可以作 为上述物理通信链路。
清洁机100被配置为在满足预设条件的情况下基于物理通信链路300向基站200发出工作指令。
本公开实施例中,清洁机与基站对接是为了接受基站提供的功能服务,即清洁机在与基站对接之前或对接上时,先判断是否有功能需求,如是否需要集尘、是否需要回收污水、是否需要补充清水以及是否需要烘干拖布等等,因此该预设条件可以包括但不限于相应的集尘条件、回收污水条件、补充清水条件以及烘干拖布条件等。存在上述需求,且满足相应条件,清洁机即可基于该物理通信链路相机站发出工作指令。
基站200被配置为执行工作指令。
本公开实施例中,上述工作指令包括控制基站执行其具有的功能的指令,如集尘指令、污水回收指令、清水补给指令、拖布烘干指令等,可以理解的是,随着基站功能的扩展,上述工作指令也相应扩展。
本公开实施例中,基站相应的设置有集尘装置、污水回收装置、清水补水装置、烘干装置中的至少一种,基站根据接收到的工作指令,控制对应的装置动作,以为清洁机提供其所需功能。
下面以集尘功能为例对清洁机及基站的结构和控制逻辑进行重点说明。
如图2所示,在某些实施方案中,清洁机100包括被配置为收集垃圾的尘盒101,尘盒具有出尘口102;基站200包括风机201,基站200还设有集尘口202及集尘空间203,集尘口202被配置为对接出尘口102,并与集尘空间203连通,风机201与集尘空间203连通,风机201被配置为将尘盒101内的垃圾抽吸至集尘空间203内;可以理解的,集尘空间203内可以采用尘袋或旋风分离器来收纳垃圾。
在某些实施方案中,出尘口和集尘口可以通过过盈配合对接,还可以在出尘口和集尘口的接触区域设置橡胶条,以使出尘口和集尘口对接时封闭对接口,防止对接口存在缝隙而泄露空气或垃 圾,由此风机在产生相同的吸力的情况下能够更好地抽吸尘盒中的垃圾,不仅提高集尘效率,还防止垃圾外泄。
在某些实施方案中,基站上还可以设置机械臂,其用于基站执行集尘指令时,控制机械臂从清洁机机体中抽出尘盒,并倾倒垃圾。
清洁机100被配置为在满足预设条件的情况下基于物理通信链路向基站发出集尘指令;基站200被配置为基于集尘指令开启风机201,风机201启动工作产生负压从而能将尘盒101内的垃圾吸入集尘空间203内。对于集尘功能来说,这里的预设条件即为集尘条件,不难理解,预设条件是与清洁机的功能相匹配的,当需要基站回收清洁机内的污水时,预设条件则为污水回收条件,其他功能同理,这里不再赘述。
在某些实施方案中,为了保证最大集尘效率,风机可以直接以最大功率运行,或者可以为了满足静音需求、节能需求等而以较小功率运行,此时为了保证集尘效果,基站可以延长风机运行时长。
在某些实施方案中,清洁机被配置为按照如下方式判断是否满足预设条件:
步骤1,确定当前时刻距离上一次集尘的期间内清洁机的累计清洁次数、累计清洁时长以及尘盒的当前剩余容积中的至少一种;需要说明的是,是否需要集尘的判断条件可以包括但不限于清洁机的累计清洁次数、累计清洁时长以及尘盒的当前剩余容积,本领域技术人员容易想到的其他可以作为是否需要集尘的判断条件亦可,例如,判断尘盒中是否存在不能直接由基站回收的特殊垃圾,如碎玻璃等,若直接由基站回收碎玻璃,可能会导致出尘口、集尘口、风机以及集尘空间损坏,因此若存在此类特殊垃圾,则清洁机不开启集尘,而是将尘盒中携带特殊垃圾的信息同步至与清洁机关联的应用程序上,以提示用户手动处理特殊垃圾。
步骤2,在累计清洁次数大于或等于次数阈值、累计清洁时长大于或等于时长阈值以及当前剩余容积小于或等于容积阈值三者中的至少一种满足的情况下,确定满足预设条件。
本公开实施例中,清洁机的累积清洁次数、累计清洁时长以及 尘盒的当前剩余容积都可以作为是否集尘的判断条件,具体地,三个条件可以设置为满足任一即可判断为满足集尘条件,需要集尘,亦或者可以设置为需同时满足两个、三个才能判定为满足集尘条件,需要集尘,例如,累计清洁次数达到3次且累计清洁时长达到15分钟,则判定满足集尘条件,否则不开启集尘。上述次数阈值、时长阈值以及容积阈值可以根据实际需要进行设置,例如,次数阈值可以为1、2、3及3以上,时长阈值可以为5min、15min、20min等,容积阈值可以是尘盒容积的1/2,1/3等等。
在某些实施方案中,清洁机向基站发出集尘指令的过程包括:控制清洁机的充电芯片交替使能和失能第一预设次数,当第一预设次数大于设定次数时,基站开启风机,充电芯片使能时发出高电平,充电芯片失能时发出低电平。
本公开实施例中,如图3所示,清洁机判断满足集尘条件,即控制充电芯片交替使能和使能第一预设次数,其中,充电芯片使能时输出高电平,充电芯片失能时输出低电平,充电芯片交替使能和失能产生循环的高低电平,当基站接收到的高低电平循环次数(即第一预设次数)大于设定次数时,基站即开启风机进行集尘。可以将大于600mA的电流值设定为逻辑高电平,将小于30mA的电流值设定为逻辑低电平。可以理解的是,高低电平的设置可以根据实际需要进行调整,如大于400mA、大于800mA可以设置为逻辑高电平,小于100mA、小于20mA可以设置为逻辑低电平。上述第一预设次数、设定次数可以根据实际需要进行设置,如设定次数为3次,则只要第一预设次数大于3次,即基站接收到大于3次的循环高低电平,即代表基站接收到集尘指令,需要开启风机对清洁机做集尘处理。
本公开实施例中,充电芯片交替使能和失能的间隔可以控制在预设间隔内,以缩短指令发送时长。另外,在充电芯片交替使能和失能期间,每次使能的持续时长可以等于或大于或小于每次失能的持续时长,这里不做唯一限定。
在某些实施方案中,基站开启风机之后,在风机开启预设时长 后,关闭风机,以结束集尘。
本公开实施例中,可以为基站的每个功能的执行时间预设执行时长,当基站执行某个功能的时长达到该功能预设的执行时长后,基站停止执行。以集尘功能为例,当基站开启风机进行集尘操作达到预设时长后,基站自动关闭风机,以结束集尘,在本实施例中,预设时长可以是10s、15s、20s等。
在某些实施方案中,清洁机可以在基站结束集尘之前判断尘盒状态,若尘盒中依然留存较多垃圾,则可以控制充电芯片交替使能和失能第一预设次数,以再次向基站发送集尘指令,进而使基站延长集尘时间。清洁机判断尘盒状态的方案,在某些实施方案中为检测当前时刻的尘盒重量,并将当前时刻的尘盒重量减去预设尘盒重量,该预设尘盒重量为清空所有垃圾的尘盒重量,当差值大于重量阈值时,判定尘盒中依然留存较多垃圾,需要继续集尘。或者,可以检测当前时刻尘盒的剩余容积,并将当前时刻尘盒的剩余容积与可用容积阈值进行对比,若剩余容积小于可用容积阈值,则判定尘盒中依然留存较多垃圾,需要继续集尘。上述重量阈值可以根据实际需求进行设置,如50克、100克、200克等,上述可用容积阈值也可以根据实际需求进行设置,如总容积的五分之一、四分之一、三分之一等。
本公开实施例中,如图3所示,在风机运转期间,充电芯片持续输出高电平,以确保集尘操作的顺利进行。
在某些实施方案中,关闭风机后,基站被配置为给清洁机充电。
本公开实施例中,基站关闭风机后,若没有接收到其他工作指令,则响应于持续接收到的高电平,基站开始给清洁机充电。充电过程包括:清洁机控制充电芯片持续使能,以向基站持续输送高电平,进而使基站对清洁机进行充电;当清洁机充电达到设定时长或当清洁机的电量达到设定电量时,控制充电芯片持续失能,以结束充电状态,此后基站可进入待机状态或休眠状态,以维持低功耗。
在某些实施方案中,控制清洁机的充电芯片交替使能和失能第一预设次数之前,控制充电芯片使能或失能至少一次。
本公开实施例中,基站并不是在一接收到清洁机发来的高低电平信号时就开始判断高低电平的循环次数从而识别工作指令,因为存在接触不稳定导致的错误电平信号,因此基站可以在接收到一段稳定电平信号后再计算高低电平的循环次数,从而保证指令接收的准确性。因此,清洁机在控制充电芯片交替使能和失能第一预设次数之前,还需要控制充电芯片使能或失能至少一次。相应的,该第一预设次数可以设置的得比设定次数相对较大,如设定次数为3次,第一预设次数可以设置为10次,从而保证基站可以准确识别到高低电平循环次数大于3次时开启风机进行集尘。
在某些实施方案中,当清洁机不满足预设条件时,控制清洁机的充电芯片交替使能和失能第二预设次数,当第二预设次数小于或等于设定次数时,充电芯片持续使能,基站给清洁机充电,充电芯片使能时发出高电平,充电芯片失能时发出低电平。
本公开实施例中,当清洁机判断不满足预设条件时,即清洁机没有特定的功能需求,此时就直接通知基站对清洁机进行充电。以清洁机判断不需要集尘为例进行说明,若不满足集尘条件,则清洁机向基站发送不集尘指令,如图4所示,即清洁机控制充电芯片交替使能和失能第二预设次数,第二预设次数小于或等于设定次数即通知基站不需要集尘,此后清洁机控制充电芯片持续使能,以向基站发出持续高电平。基站接收到该不集尘指令的情况下,即不需要开启风机,并在无其他指令的情况下,基站响应该持续高电平对清洁机进行充电,即当第二预设次数小于或等于设定次数时,充电芯片持续使能,向基站持续输出高电平,进而使基站给清洁机充电。在本实施例中,设定次数可以是3次,相应的第二预设次数可以是3次、2次或者1次,这里不做唯一限定。
同样地,控制清洁机的充电芯片交替使能和失能第二预设次数之前,控制充电芯片使能或失能至少一次,以确保基站接收指令的准确性。
在某些实施方案中,上述物理通信链路可以基于触点实现。在某些实施方案中,清洁机上设置有充电触点,基站上设置有供电触 点,充电触点被配置为和供电触点电连接,以形成物理通信链路。也即,本实施例中,清洁机与基站之间不仅通过充电触点与供电触点的电接触实现基站对清洁机的充电,还通过充电触点与供电触点的电接触实现清洁机对基站的指令传输,比如,集尘指令、污水回收指令、清水补给指令、拖布烘干指令等。
本公开实施例中,清洁机与基站之间通过物理通信链路进行指令发送、数据传输,可以不需要在基站上独立安装通信模块,节省成本,而是仅仅依靠触点接触,在基站向清洁机充电时,通过清洁机的充电触点和基站的供电触点构建该物理通信链路,以供清洁机向基站发送工作指令。可以理解地,在其他实施方式中,也可以采用其他方式建立清洁机与基站之间的物理通信链路,比如,清洁机与基站之间通过充电触点与供电触点的电接触实现基站对清洁机的充电,通过其他触点实现清洁机对基站的指令传输。基于此方式,清洁机可以实现充电与指令发送同时进行。
在某些实施方案中,基站也可以通过充电触点、供电触点电接触所形成的物理通信链路向清洁机发送基站状态数据,或者通过其他触点电接触形成的物理通信链路向清洁机发送基站状态数据。本实施例中,基站状态数据包括但不限于基站尘袋积尘容量、清水箱水量、污水箱水量、风机状态等工作状态信息。
本实施例中,当基站通过物理通信链路向清洁机发送信号时,清洁机接收基站通过物理通信链路发送的目标电平信号,解析目标电平信号,得到基站的状态信息,将状态信息同步至与清洁机和基站关联的目标应用程序,以通过目标应用程序展示状态信息。用户通过目标应用程序能够实时了解清洁机及基站的工作状态,当清洁机或基站出现异常时还能及时处理。
在某些实施方案中,充电触点与供电触点的数量为至少一对,每一对均可实现该物理通信链路,则在存在多条物理通信链路的情况下,清洁机与基站之间可以同时进行数据通信。
