图11是根据本申请的一些实施例所示的探测组件以串并混合方式连接到数据控制板时的示例数据采集模块的示意图。如图11所示，探测组件210-1，210-2，……，210-(k-1)(k可以表示任何大于1的整数)以串联方式与数据控制板220相连，探测组件210-(k-1)与数据控制板220直接相连，探测组件210-1，210-2，……，通过探测组件210-(k-1)与数据控制板220相连。探测组件210-m，……，210-n(m，n可以表示任何大于1的整数)以串联方式与数据控制板220相连，探测组件210-n与数据控制板220直接相连，探测组件210-m，……，通过探测组件210-n与数据控制板220相连。类似地，其他探测组件可以以并联(例如，探测组件210-5和210-6以并联方式与数据控制板220直接相连)、或串联方式等与数据控制板220相连。探测组件210-1,210-2，……，210-(k-1)，……，210-m，……，210-n与数据控制板220之间的工作过程同图9描述的类似。在一些实施例中，探测组件210-1，210-2，……，210-(k-1)，……，210-m，……，210-n可以使用相同的线缆设计，信号在系统的电路板和线缆上的飞行时间相同；所述探测组件的型号及硬件程序可以相同，使得每个探测组件的处理时间保持相同。在一些实施例中，当两个探测组件以并联方式连接到数据控制板220时，补偿相同的时间延迟。在一些实施例中，当两个探测组件以串联方式连接到数据控制板220时，补偿不同的时间延迟。例如， 探测组件210-3直接连接到数据控制板220，探测组件210-4和210-5分别直接连接到探测组件210-3并通过探测组件210-3连接到数据控制板220。对探测组件210-3补偿的时间延迟可以为T3，则对探测组件210-4和210-5补偿的时间延迟可以为T3-C1。同T1和C类似，T3和C1代表一个时间值。
图12是根据本申请的一些实施例所示的探测组件以串并混合方式连接到数据控制板时的示例数据采集模块的示意图。所述数据采集模块可以包括探测组件210-1，……,210-k，……，210-n(k，n可以表示任何大于1的整数)，和一个数据控制板220。探测组件210可以包括一个时钟恢复模块510，一个判断模块520，一个补偿模块530和一个解析模块540。
如图12所示，探测组件210-1，……，210-k，……，210-n与数据控制板220相连，与数据控制板220组成多个通道。例如，探测组件210-1，……，210-k与数据控制板220组成第一个通道，在所述第一个通道中，探测组件210-1，……，210-k之间串联连接，探测组件210-k与数据控制板220直接相连。数据控制板220可以通过探测组件210-k的引脚识别所述第一个通道。在所述第一个通道中，探测组件210-1，……，210-k可以对应不同的通道位置号，所述通道位置号可以是连续的编号，所述连续的编号可以是数字、字母、或者下划线等标识符中的一种或几种的组合。在所述第一个通道中，探测组件210-1，……，210-k和数据控制板之间可以通过探测组件210-k进行信息(例如，一个命令数据包)的传递。类似的，探测组件210-n可以与其他一个或多个探测组件以并联、串联或串并混合等方式连接到数据控制板220，并与数据控制板220组成第N个通道(N可以表示任何大于1的整数)，探测组件210-n与数据控制板220直接相连。
上文已对基本概念做了描述，显然，对于本领域技术人员来说，上述发明披露仅仅作为示例，而并不构成对本申请的限定。虽然此处并没有明确说明，本领域技术人员可能会对本申请进行各种修改、改进和修正。该类修改、改进和修正在本申请中被建议，所以该类修改、改进、修正仍属于本申请示范实施例的精神和范围。
同时，本申请使用了特定词语来描述本申请的实施例。如“一个实施例”、“一实施例”、和/或“一些实施例”意指与本申请至少一个实施例相关的某一特征、结构或特点。因此，应强调并注意的是，本说明书中在不同位置两次或多次提及的“一实施例”或“一个实施例”或“一替代性实施例”并不一定是指同一实施例。此外，本申请的一个或多个实施例中的某些特征、结构或特点可以进行适当的组合。
此外，本领域技术人员可以理解，本申请的各方面可以通过若干具有可专利性的种类或情况进行说明和描述，包括任何新的和有用的工序、机器、产品或物质的组合，或对他们的任何新的和有用的改进。相应地，本申请的各个方面可以完全由硬件执行、可以完全由软件(包括固件、常驻软件、微码等)执行、也可以由硬件和软件组合执行。以上硬件或软件均可被称为“数据块”、“模块”、“引擎”、“单元”、“组件”或“系统”。此外，本申请的各方面可能表现为位于一个或多个计算机可读介质中的计算机产品，该产品包括计算机可读程序编码。
计算机可读信号介质可能包含一个内含有计算机程序编码的传播数据信号，例如在基带上或作为载波的一部分。该传播信号可能有多种表现形式，包括电磁形式、光形式等等、或合适的组合形式。计算机可读信号介质可以是除计算机可读存储介质之外的任何计算机可读介质，该介质可以通过连接至一个指令执行系统、装置或设备以实现通讯、传播或传输供使用的程序。位于计算机可读信号介质上的程序编码可以通过任何合适的介质进行传播，包括无线电、电缆、光纤电缆、RF、或类似介质、或任何上述介质的组合。
本申请各部分操作所需的计算机程序编码可以用任意一种或多种程序语言编写，包括面向对象编程语言如Java、Scala、Smalltalk、Eiffel、JADE、Emerald、C++、C#、VB.NET、Python等，常规程序化编程语言如C语言、Visual Basic、Fortran 2003、Perl、COBOL 2002、PHP、ABAP，动态编程语言如Python、Ruby和Groovy，或其他编程语言等。该程序编码可以完全在用户计算机上运行、或作为独立的软件包在用户计算机上运行、或部分在用户计算机上运行部分在远程计算机运行、或完全在远程计算机或服务器上运行。在后种情况下，远程计算机可以通过任何网络形式与用户计算机连接，比如局域网(LAN)或广域网(WAN)，或连接至外部计算机(例如通过因特网)，或在云计算环境中，或作为服务使用如软件即服务(SaaS)。
此外，除非权利要求中明确说明，本申请所述处理元素和序列的顺序、数字字母的使用、或其他名称的使用，并非用于限定本申请流程和方法的顺序。尽管上述披露中通过各种示例讨论了一些目前认为有用的发明实施例，但应当理解的是，该类细节仅起到说明的目的，附加的权利要求并不仅限于披露的实施例，相反，权利要求旨在覆盖所有符合本申请实施例实质和范围的修正和等价组合。例如，虽然以上所描述的系统组件可以通过硬件设备实现，但是也可以只通过软件的解决方案得以实现，如在现有的服务器或移动设备上安装所描述的系统。
同理，应当注意的是，为了简化本申请披露的表述，从而帮助对一个或多个发明实施例的理解，前文对本申请实施例的描述中，有时会将多种特征归并至一个实施例、附图或对其的描述中。但是，这种披露方法并不意味着本申请对象所需要的特征比权利要求中提及的特征多。实际上，实施例的特征要少于上述披露的单个实施例的全部特征。
一些实施例中使用了描述成分、属性数量的数字，应当理解的是，此类用于实施例描述的数字，在一些示例中使用了修饰词“大约”、“近似”或“大体上”来修饰。除非另外说明，“大约”、“近似”或“大体上”表明所述数字允许有±20％的变化。相应地，在一些实施例中，说明书和权利要求中使用的数值参数均为近似值，该近似值根据个别实施例所需特点可以发生改变。在一些实施例中，数值参数应考虑规定的有效数位并采用一般位数保留的方法。尽管本申请一些实施例中用于确认其范围广度的数值域和参数为近似值，在具体实施例中，此类数值的设定在可行范围内尽可能精确。
针对本申请引用的每个专利、专利申请、专利申请公开物和其他材料，如文章、书籍、说明书、出版物、文档、物件等，特此将其全部内容并入本申请作为参考。与本申请内容不一致或产生冲突的申请历史文件除外，对本申请权利要求最广范围有限制的文件(当前或之后附加于本申请中的)也除外。需要说明的是，如果本申请附属材料中的描述、定义、和/或术语的使用与本申请所述内容有不一致或冲突的地方，以本申请的描述、定义和/或术语的使用为准。
最后，应当理解的是，本申请中所述实施例仅用以说明本申请实施例的原则。其他的变形也可能属于本申请的范围。因此，作为示例而非限制，本申请实施例的替代配置可视为与本申请的教导一致。相应地，本申请的实施例不仅限于本申请明确介绍和描述的实施例。
