对主从结构而言，主机和从机修护、安装和更换灵活可变且方便，只是每次安装后，都需要以人工录入的方式重新让主机获取对应从机的地址，不仅操作繁琐，且容易出错，不适于大规模普及。

具体实施方式
为使本申请的上述目的、特征和优点能够更加明显易懂，下文中将结合附图对本发明的具体实施方式做详细说明。下文所描述的各具体实施方式仅为示例，并非用以限制本发明。在不违背本发明精神的情况下，能够实现本申请实施例的各类修改、改进和变换均由本申请所附的权利要求书所涵盖。
在本申请中，术语“通信”有时也使用“通讯”。
图1是一种主从通信系统的结构示意图。如图所示，该主从通信系统包括主机110和多个从机120。多个从机120中的每一个都被配置有唯一的编码地址。各从机120通过并行线路220并行连接到主机110。例如，图中示例的三个从机120，彼此以并行连接的方式连接到主机110，从而在主机110与各从机120之间分别构建通信线路。此外，主机110与多个从机120以主机110位首通过串联线路210串行连接，也就是说，主机110是该串行连接中的第一个节点。在本申请的示例中，将与主机110直接串行连接的从机称呼为第一从机。
图2是根据本申请示例的从机位置识别方法的流程图，下文将结合图1阐述如图2所示的从机位置识别方法的执行。
在步骤S10，多个从机120中的第一从机通过串联线路210接收主机110发送的位置识别信息，处理该位置识别信息并获取自身相对于主机的位置信息。按照本申请的一些示例，主机110通过串联线路210所发送位置识别信息包括用于多个从机的位置信息。
依次串行连接的各从机，分别通过串联线路210接收前一从机通过串联线路发送的处理后的位置识别信息，处理并获取自身相对于主机的位置信息。依次串行连接的各从机是以第一从机为首，包括依次串行的其它从机。在各从机的串行连接中，前一从机是发送给当前从机位置识别信息的从机，按照本申请， 前一从机即串行连接中挨着当前从机且更早接收到位置识别信息的从机。在下文的一些示例中，也将前一从机称作上一个从机，相对地将当前从机称作下一个从机。
在步骤S20，主机110通过并行线路220分别与各从机120通信以获取各从机的编码地址。编码地址是各从机的识别地址。
根据本申请的一些示例，从机对位置识别信息进行处理指的是从机从位置识别信息中获取其自身相对于主机的位置信息并从位置识别信息中删除自身相对于主机的位置信息(也称作自身位置信息)，由此，处理后的位置识别信息中将包括尚未收到位置识别信息的各从机的位置信息，而不再包括当前从机自身位置信息。根据本申请的又一些示例，从机对位置识别信息进行处理指的是从机从位置识别信息中获取其自身相对于主机的位置信息，并按照预设的相关算法产生用于其它从机的位置信息。从机对位置识别信息进行处理的方式还可以是其它形式，只要能够使得各从机具有可标识的相对于主机的位置即可。
在本申请中，用于多个从机并行连接到主机的并行线路只要能够实现主机与各从机的并行通信即可，本申请并不对其具体的实现进行限制。同样地，用于主机和各从机串行连接的串联线路也可采用各种实现方式，只要能够实现从主机开始到各从机的串行连接即可。举例来说，通过主机、从机的串行接口依次连接从而实现串行连接等。
下文将同时参照图1至图4阐述根据本申请的一种示例性的从机识别方法。在该示例性的描述中，示例而非限制地，用于实现串行连接的串联线路称作串联总线，用于实现并行连接的并行线路称作通信总线。
一种主从通信系统的从机位置识别方法，所述主从通信系统包括主机110和多个从机120，每一所述从机120均包括唯一的编码地址，所述主机110和 从机120均通过通信总线220并联连接，且通过串联总线210以主机110为首的串联连接。
按照本示例，设置了一个主机110及多个与主机110配合的从机120。主机110包括具有发送功能的第一主机引脚111和具有信息通讯功能的第二主机引脚112，从机120包括具有接收功能的第一从机引脚121、具有发送功能的第二从机引脚122和具有信息通讯功能的第三从机引脚123，其中，主机110通过第二主机引脚112接入通讯总线220，从机120通过第三从机引脚123接入通讯总线220，以及，主机110通过第一主机引脚111与从机120的第一从机引脚121连接，实现串联通信。从机120再通过第二从机引脚122与下一个从机120的第一从机引脚121连接，实现串联通信。主机110和从机120均通过通信总线220实现“一问一答”的通信，主机110和从机120通过串联总线210实现以主机110为首的依次串联通信，将主机110的输出信号依次传输至各从机120中。
其中，主机110和从机120之间均设有对应的处理模块(如处理器或处理电路)，以实现各种功能。为了提高语言简洁性，本示例中提出的主机110和从机120的相关功能操作，默认是由其内部的处理模块实现，以及相关引脚是指处理模块的引脚。
参考图2，在本实施例中，所述从机位置识别方法包括步骤：
步骤S10、从机120通过串联总线210依次接收及处理从主机110发送的位置识别信息，并获取自身相对于主机110的位置信息；
步骤S20、主机110通过通信总线220与各位置的从机120进行通信，获取对应位置上从机120的编码地址。
通过串联总线210将主机110的位置识别信息依次发送至各从机120中， 根据各从机120的接收顺序，获取不同的位置信息，从而获取自身相对于主机110的位置信息。以及，再通过各从机120已知自身位置信息的基础上，通过通信总线220进行地址识别通信，获取每一位置上的从机120所对应的编码地址，从而实现在不知道从机120信息的基础上，智能获取各位置上从机120的编码地址。
根据本申请的实施例，所述位置信息是各从机相对于主机的先后排列顺序。
结合图3进一步阐述根据本申请示例的从机位置识别方法。
在步骤S11，主机110通过串联总线210发送位置识别信息，每一从机120在接收到位置识别信息后进行处理，并将处理后的位置识别信息通过串联总线210发送至下一个从机120。
在步骤S12，从机120分别从位置识别信息中获取自身相对于主机110的位置信息。
在步骤S21，主机110再通过通信总线220发送包含位置信息的地址配对信息给各相应的从机，从机120在接收到地址配对信息后进行处理以提取所述位置信息。
在步骤S22，从机120将对与自身位置信息相同的地址配对信息进行处理，形成具有编码地址的配对成功信息，并通过通信总线220发送配对成功信息至主机110。与自身位置信息相同指的是地址配对信息中包含的位置信息即为接收到该地址配对信息的从机的位置信息。
步骤S23、主机110根据配对成功信息获取对应位置上从机120的编码地址。
具体的，通过步骤S11和步骤S12，依靠串联总线210需要经过每一从机120才能到下一从机120的特性，从机120通过串联总线210发送位置识别信 息，位置识别信息应包括对应的位置信息，或在经过从机120后，为下一个从机120提供新的位置信息。例如，位置识别信息为一串连续数字的字符串，如1至9排序的字符串，第一位置的从机120获取位置识别信息后，根据预设算法提取第一位的数字，再将所述位置识别信息修改，如删除第一位字符串形成新的位置识别信息，并发送给下一个从机120，每一从机120将获取对应位置，即相对于主机110位置的位置信息。再例如，位置识别信息为一编码，第一个从机120先接收所述编码，并通过预设算法或数据库提取位置信息，即可通过编码认为当前从机120的位置信息为“1号”，再通过预设算法或数据库将编码修改为另一可被从机120识别且表示“2号”的新的位置识别信息，通过上述操作每一从机120均可获取对应位置，即相对于主机110位置的位置信息。
以及，通过步骤S21至步骤S23，依靠通信总线220实现主机110和多个从机120的通信，例如每一从机120均获取自身相对于主机110的位置信息，通过包含特定位置信息的地址配对信息，获取每一位置信息所对应的地址，即，主机110经由通信总线220分别与各从机120的相互通信，使得主机110能获取每一位置的从机120的编码地址。后续，主机110根据智能控制或远程命令控制，根据已获知的编码地址来实现对对应于该编码地址的从机120的控制。根据本申请示例的从机位置识别方法，主机110可智能获取各从机120的编码地址，而无需要提前知晓从机120编码地址，由此提高了主机110和从机120结构的灵活性。据此，在修护、安装和更换过程中，不需要工作人员特意将编码地址输入至主机110或总系统中，即使后续由于工作人员将各从机120的位置调换，也能及时获取对应编码地址的从机120的位置。
举例来说，从机120将对与自身位置信息相同的地址配对信息进行处理是将自身地址增加至地址配对信息中形成配对成功信息。如地址配对信息是(1) AAA，配对成功信息是(1)(XXX)AAA，其中(1)属于位置信息，(XXX)属于编码地址，AAA属于附加信息。再例如，将自身地址融合至地址配对信息中形成配对成功信息，如地址配对信息是(1)AAA，配对成功信息是(1XXX)AAA或(1)AXAXAX，主机110可通过特定算法将编码地址XXX提取出，防止信号干扰，提高保密性能。当然，所述串联总线210和通信总线220均可通过高低电平实现，这均属于现有信息传输的常规技术，不再一一描述。
图4是根据本申请示例的从机120处理地址配对信息的流程图。如图4所示，在步骤S221，从机120接收到地址配对信息后进行处理以提取所述位置信息。在步骤S222，从机120将从地址配对信息提取的位置信息与从位置识别信息获取的位置信息进行比较，若符合预设地址匹配条件，则对地址配对信息进行处理。在步骤S223，形成具有编码地址的配对成功信息，并通过通信总线220发送配对成功信息至主机110。
在本例中，接收到地址配对信息的从机120将地址配对信息中位置信息与其从位置识别信息中获取的位置信息进行比较以判断是否匹配，是为了避免误处理并非针对本从机的地址配对信息。例如，若地址配对信息是主机110特意发送给该从机120的，该从机120进行处理形成配对成功信息，反馈回主机110，若地址配对信息是主机110特意发送给其他从机120的，该从机120不进行处理。
一般处理方式均是提取所述地址配对信息的位置信息，并与从机120自身的位置信息进行比较，相同就进行后续处理，反之就不处理。
图5是根据本申请示例的基于通知信息的从机位置识别方法的流程图。图6是图5所示例的方法的进一步细化。
参照图5与图1，在步骤S31，主机110先通过通信总线220发送通知信 息，从机120通过通信总线220接收到通知信息后等待接收位置识别信息；其中，通知信息用于指示各从机等待接收位置识别信息。然后，在步骤S32，主机110通过串联总线210发送位置识别信息，每一从机120在接收到位置识别信息后进行处理，并将处理后的位置识别信息通过串联总线210发送至下一个从机120。步骤S32的过程上文已结合各示例描述，不再赘述。
具体的，通知信息最主要作用是防止从机120过多，主机110的位置识别信息无法使全部从机120获取自身位置信息，或者由于中途出错，位置识别信息没有及时传输至对应的从机120中。主机110先通过通信总线220发送通知信息，通知接入通信总线220的所有从机120，主机110将要进行位置信息确定的步骤，从机120进入对应工作模式，等待接收位置识别信息。
参考图6，在步骤S311，主机110通过通信总线220发送通知信息。在步骤S312，从机120通过通信总线220接收到通知信息后，在预设时间内等待接收位置识别信息。在步骤S33，若从机120在预设时间内没有接收到位置识别信息，通过通信总线220发送指示位置识别信息接收失败的反馈信息。在步骤S34，主机110根据指示位置识别信息接收失败的反馈信息获取没有接收到位置识别信息的从机120数量或从机120编码地址，且主机110重新调整位置识别信息，意在使当前所有的从机120都可从位置识别信息中获取位置信息，并再次通过串联总线210发送调整后的位置识别信息。
具体是，当某一从机120在规定时间内未接收到位置识别信息，可认为从机120无法获取自身位置信息，从机120反馈回主机110，即从机120通过通信总线220发送指示位置识别信息接收失败的反馈信息。主机110根据失败反馈信息获取没有接收到位置识别信息的从机120数量或从机120编码地址，且主机110重新调整位置识别信息以满足对应数量的从机120，再次通过串联总 线210发送位置识别信息。智能地调节位置识别信息的内容，以使得不同从机120均可获取自身位置信息。
根据本申请的一些示例，还提供一种主从通信系统。与图1所示的主从通信相比，该主从通信系统可为一个从机或多个从机配置与其并联的可控开关，该可控开关由与其并联的所述从机控制，在受控的情况下，常开；且在未受控的情况下闭合。未受控的情况发生在与该可控开关并联的从机故障、断电等该从机未正常工作的情况下。
如图7所示，所述主从通信系统包括与从机120串联总线210的收发端并联的可控开关300，可控开关300的控制端与对应从机120的控制引脚连接，所述可控开关300在从机120的控制下常开，且当从机120不能正常工作时不再控制可控开关300，可控开关300进入常闭状态。
具体的，每一从机120的第一从机引脚121和第二从机引脚122通过一可控开关300连接，可控开关300包括设置在第一从机引脚121和第二从机引脚122之间的开关310和控制开关310的开启或关闭的控制器320，所述从机120还包括控制控制器320工作的第四从机引脚124，从机120通过第四从机引脚124控制控制器320，以控制开关310常开。以及，在主从通信系统上电时，可控开关300均在从机120控制下，进入常开，当可控开关300脱离从机120的控制，进入常闭，即当从机120有问题不能正常工作，可直接短路第一从机引脚121和第二从机引脚122，使位置识别信息忽略所述从机120，直接进入下一从机120，实现通信的断点传输，提高系统的可靠性。
进一步地，控制器320还接地，实现第四从机引脚124的控制信号的有效传输。
根据本申请的一些示例，还提供用于移动电源的租借装置。
该用于移动电源的租借装置，包括主从通信系统，以及放置于从机的移动电源。主机根据智能控制或远程命令控制，实现从机作为租借设备的正常工作。该用于移动电源的租借装置的主机可采用上文结合各示例描述的主机110，该用于移动电源的租借装置的从机包括一个或多个用于容纳移动电源的容纳仓，或者说电池仓，上文结合各示例描述的从机120可被实现在该用于移动电源的租借装置的从机中。由此，在该用于移动电源的租借装置中可实现上文结合各附图所描述的从机位置识别方法，进而灵活地管理从机。
