数字示波器是电子工程师常用的基本工具，随着技术的发展，数字示波器一次测量中，短时间可以记录下来大量的波形，在后续分析时，需要把之前记录下来的波形找出来。在现有技术中，数字示波器的存储方式通常有单段或者多段存储方式。在单段储存方式下，波形寻找的方式通常是在波形显示区域上方设一个导航区，在导航区设有标志，提示波形显示区域的波形在整个记录数据中的位置和大小；而在多段存储方式下，通常的波形查找方法是逐个波形翻查。因此，当波形的记录深度不深，例如只有几屏或者几十屏波形，在上述两种查找方式不失为方便的方式。但是，记录的深度决定了其测量波形的多少，在现在的技术条件下，用户通常会希望大的存储深度，近年的技术发展的趋势也是这样的。但是，如果波形的记录深度很深，例如，记录了几千个或者几十万个波形的时候，如果再用上述两种查找方法，就变成很没有效率了，因为这种逐一查看的方式很难从几千个或几十万个波形中找到用户希望看到的异常波形的具体位置。

具体实施方式
为了使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的技术方案进行清楚、完整的描述，显然，所描述的实施例是本发明的部分实施例，而不是全部实施例。基于本发明的实施例，本领域普通技术人员在没有付出创造性劳动的前提下所获得的所有其他实施例，都属于本发明的保护范围。
本发明较佳实施例的数字示波器的波形搜索方法流程如图1所示，同时参阅图10和图11，该方法用于快速从至少数千条波形中搜索到目标波形，包括以下步骤：
步骤S1、在获取到用户输入的波形搜索模式触发指令时，进入波形搜索模式；
步骤S2、在波形搜索模式下，在搜索导航区显示第一层波形搜索条，第一层波形搜索条包含：对待查找的所有波形按预设规则进行划分而得到的多个一级区块，每个一级区块对应包含一条或者多条波形数据；
步骤S3、突出显示当前搜索指针对应的一级区块，实时获取用户输入的搜索指针位置调整信息，并根据新的当前搜索指针位置对应突出显示新的一级区块；
步骤S4、在波形显示区中，以重叠方式显示当前搜索指针对应的一级区块中所包含的所有波形；
步骤S5&S6、直接在搜索导航区显示第二层波形搜索条(即图1中虚线箭头指示的流程)，或者在获取到用户输入的选择进一步查看某个一级区块的指令时，进一步在搜索导航区显示第二层波形搜索条；第二层波形搜索条包含：对第一层波形搜索条中被选择的一级区块中所包含的所有波形按预设规则进行进一步划分而得到的多个二级区块，所有二级区块中所包含的波形条数总和 等于被选择的一级区块中的波形条数；
步骤S7、第一层波形搜索条中搜索指针位置不变，将当前搜索指针位置移至第二层波形搜索条，突出显示当前搜索指针对应的二级区块，第一层波形搜索条中被选择查看的一级区块保持突出显示状态；
步骤S8、实时获取用户输入的搜索指针位置调整信息，并根据新的当前搜索指针位置改变突出显示的二级区块；
步骤S9、在波形显示区中以重叠方式显示当前搜索指针对应的二级区块中所包含的一条或多条波形。
通过上述步骤S2-S9，可对数千条、数万条、甚至数十万条波形进行初步的一级区块划分，每个一级区块对应包含一条或者多条波形数据，并以波形搜索条的形式进行区块显示，方便用户进行分区查找，同时在波形搜索区以重叠的方式对当前搜索指针对应的一级区块中包含的所有波形进行显示，用户可直接看到当前搜索指针对应的一级区块中是否有异常波形，如果有异常波形，用户可进一步进行第二层波形搜索条，查看当前一级区块内的所有波形，而在第二层波形搜索条中，再进一步将所包含的波形进行二级区块的划分，并在波形显示区重叠显示当前搜索指针对应的二级区块中的所有波形，使得异常波形所在位置更加容易查找。
如图10所示，当前在搜索条导航区显示的是第一层波形搜索条A1，在波形显示区B中重叠显示的是第一层波形搜索条中T1指示的一级区块中包含的所有波形。
如图11所示，当前在搜索条导航区显示的是第一层波形搜索条A1和第二层波形搜索条A2，在波形显示区B中重叠显示的是第二层波形搜索条中T2指示的二级区块中包含的所有波形。
优选地，如图2所示，同时参阅图12，上述波形搜索方法进一步包括：
步骤S21、直接在搜索导航区显示第三层波形搜索条，或者在获取到用户输入的选择进一步查看某个二级区块的指令时，进一步在搜索导航区显示第三层波形搜索条；第三层波形搜索条包含：对第二层波形搜索条中被选择的二级区块中所包含的所有波形，按该二级区块的波形条数，以预设规则进行进一步划分而得到的多个三级区块，所有三级区块中所包含的波形条数均等，并且总和等于被选择的二级区块中的波形条数；
步骤S22、第二层波形搜索条中搜索指针位置不变，即第二层波形搜索条的突出显示的区块保持突出显示状态，将当前搜索指针位置移至第三层波形搜索条，突出显示当前搜索指针对应的三级区块；
步骤S23、实时获取用户输入的搜索指针位置调整信息，并根据新的当前搜索指针位置改变突出显示的三级区块；
步骤S24、在波形显示区中以重叠方式显示当前搜索指针对应的三级区块中所包含的一条或多条波形。
通过上述步骤S21-S24，在第二层波形搜索条中找到目标异常波形所在二级区块后，可将待查看波形进行进一步的分层显示，以缩短查找时间，提高查找效率。
如图12所示，当前在搜索条导航区显示的是第一层波形搜索条A1和第二层波形搜索条A2、第三层波形搜索条A3，在波形显示区B中重叠显示的是第三层波形搜索条中T3指示的三级区块中包含的所有波形。
更优选地，如图3所示，同时参阅图13，上述波形搜索方法进一步包括步骤：
步骤S31、直接在搜索导航区显示第四层波形搜索条，或者在获取到用户 输入的选择进一步查看某个三级区块的指令时，进一步在搜索导航区显示第四层波形搜索条；第四层波形搜索条包含：对第三层波形搜索条中被选择的三级区块中所包含的所有波形按预设规则进行进一步划分而得到的多个四级区块，所有四级区块中所包含的波形条数均等，并且总和等于被选择的三级区块中的波形条数；
步骤S32、第三层波形搜索条中搜索指针位置不变，即第三层波形搜索条的突出显示的区块保持突出显示状态；将搜索指针位置移至第四层波形搜索条，突出显示当前搜索指针对应的四级区块；
步骤S33、实时获取用户输入的搜索指针位置调整信息，并根据新的当前搜索指针位置改变突出显示的四级区块；
步骤S34、在波形显示区中以重叠方式显示当前搜索指针对应的四级区块中所包含的一条或多条波形。
通过上述步骤S31-S34，在第三层波形搜索条中找到目标异常波形所在三级区块后，可将待查看波形进行进一步的分层显示，以缩短查找时间，提高查找效率。
如图13所示，当前在搜索条导航区显示的是第一层波形搜索条A1和第二层波形搜索条A2、第三层波形搜索条A3、第四层波形搜索条A4，在波形显示区B中重叠显示的是第四层波形搜索条中T4指示的四级区块中包含的所有波形。
如图4所示，当用户需要将搜索指针从第二层波形搜索条返回至第一层波形搜索条，查看另一一级区块中的所有波形时，上述方法进一步包括：
步骤S41、判断是否获取到用户输入的选择退出查看当前层波形搜索条的指令？其中，当前层波形搜索条具体是指上述第二层波形搜索条、第三层波形 搜索条或第四层波形搜索条。
步骤S42、在搜索导航区取消显示当前层波形搜索条，将搜索指针移回到上一层波形搜索条中当前被突出显示的区块。其中，上一层波形搜索条具体是指上述第一层波形搜索条、第二层波形搜索条、第三层波形搜索条。
通过上述步骤S41-S42，可方便用户从下一层波形搜索条退回至上一层波形搜索条，以进一步查看上一层波形搜索条中另一区块内的波形。
如图11所示，当前搜索指针位于第二层波形搜索条的T2对应的二级区块位置，如此时获取到用户输入的退出查看第二层波形搜索条，欲返回第一层波形搜索条，则下一显示状态对应如图10所示，第二层波形搜索条消失，当前搜索指针回到第一层波形搜索条中T1对应的一级区块位置。
上述波形搜索方法中，如图5所示，同时参阅图1、图2和图3，在波形显示区中，以重叠方式显示当前搜索指针对应的一级区块、二级区块、三级区块或四级区块中所包含的所有波形的具体方式包括：
步骤S51、以两个状态交替显示；
其中，参阅图13，第一状态为，以第一特征颜色重叠显示当前区块中的所有波形，同时以第二特征颜色重叠显示当前层中除去当前块中波形之外的所有波形；
参阅图14，第二状态为，隐藏第一状态中以第一特征颜色重叠显示的当前区块中的所有波形，而只以第二特征颜色重叠显示当前层中除去当前块中波形之外的所有波形；
例如，第一特征颜色为高亮色，第二特征颜色为红色或其他彩色的背景色；
其中，当前区块为一级区块、二级区块、三级区块或四级区块，一级区块对应的当前层为第一层波形搜索条，二级区块对应的当前层为第二层波形搜索 条，三级区块对应的当前层为第三层波形搜索条，四级区块对应的当前层为第四层波形搜索条。
通过采用上述第一状态和第二状态的交替显示，可更加快速的分辨出当前区块中是否包含待寻找的目标异常波形。如图14中，当隐藏当前区块中的波形后，剩余的波形中，目标特征消失，则说明需要寻找的特征波形仅包含在当前区块中，用户只需在当前区块中进一步查找即可，进一步提高了波形查找效率。
如图6所示，上述波形搜索方法进一步包括：
步骤S61、在波形搜索模式下，实时检测用户是否输入书签设置指令；
步骤S62、在获取到用户输入的书签设置指令时，记录波形显示区中当前显示的一条或多条波形对应的显示参数，显示参数包括时基信息、时延信息、当前块信息、当前层信息、波形颜色信息和触发设置信息；
步骤S63、存储在一次书签设置指令下所记录的全部显示参数，并以一个书签标记按钮作为触发形式显示在数字示波器的人机交互界面中。
如图7所示，上述波形搜索方法进一步包括步骤：S71、在波形搜索模式下，实时检测用户是否选择书签标记按钮；S72、在获取到用户选择书签标记按钮的触发信息时，读取所存储的该书签标记按钮对应的全部显示参数；S73、将所读取的全部显示参数加载至当前波形显示系统，以将波形显示区B的波形显示还原至书签标记时的状态。
通过上述步骤S61-S63以及步骤S71-S73，使得用户在波形搜索模式下，可随时对当前查看的波形设置书签，以便于通过该书签功能随时回看感兴趣的波形区块。
优选地，上述波形搜索方法中，在获取到用户输入的多次书签设置指令时， 分别记录各个书签设置指令对应的显示参数，并在数字示波器的人机交互界面显示多个不同的书签标记按钮。用户可根据需要设置一个或多个书签标记按钮，进一步提高波形查找效率。
进一步地，上述波形搜索方法中，搜索指针移动方式为：根据用户输入的搜索指针位置调整信息，将搜索指针在当前层波形搜索条的多个区块上连续滑动、以依次突出显示当前层波形搜索条上相邻的区块，当前层波形搜索条为第一层波形搜索条、第二层波形搜索条、第三条波形搜索条或第四条波形搜索条；或者，根据用户输入的搜索指针位置调整信息，将搜索指针在不同层的波形搜索条之间移动，以供选择进一步查看某个区块对应的下一层波形，或者退出观察某一层波形，回到上一层的区块。
进一步地，上述波形搜索方法中，如图9所示，搜索指针移动方式进一步包括以下步骤：
步骤S81、实时检测搜索指针位置对应的区块是否为边界区块，其中边界区块包括：第二层波形搜索条的左侧边界区块或右侧边界区块、第三层波形搜索条的左侧边界区块或右侧边界区块、第四层波形搜索条的左侧边界区块或右侧边界区块；
步骤S82、判断是否获取到用户输入的向左调整搜索指针位置的调整信息？
步骤S83、在搜索指针位置对应的区块为左侧(或右侧)边界区块，且获取到用户输入的向左(或向右)调整搜索指针位置的调整信息时，暂不执行该次搜索指针位置调整指令，开始计数和计时；
步骤S84、判断计时是否满足预设时间？
步骤S85、当计时满足预设时间后，看计数是否满足预设计数值；
步骤S86、若否，则取消该次搜索指针位置调整指令；
步骤S87、若是，则将搜索指针位置调整至当前左侧(或右侧)边界区块对应的上一层波形搜索条中当前突出显示区块的左侧(或右侧)区块位置。
同样，根据上述步骤S81-S87可知，在搜索指针位置对应的区块为右侧边界区块，且获取到用户输入的向右调整搜索指针位置的调整信息时，暂不执行该次搜索指针位置调整指令，开始计数和计时，当计时满足预设时间后，看计数是否满足预设计数值，若否，则取消该次搜索指针位置调整指令，若是，则将搜索指针位置调整至当前右侧边界区块对应的上一层波形搜索条中当前突出显示区块的右侧区块位置。
根据上述步骤，当用户需要跨边界操作搜索指针时，会遇到上述故意设置的操作障碍，以便于提醒用户该操作将同时改变上一层的搜索指针位置和当前层的搜索指针位置，增强操作感，防止误操作。
例如，第一层波形搜索模块有120个一级区块，当前突出显示的是第50个一级区块；第二层波形搜索模块有60个二级区块，当前突出显示的是从左往右数的第1个二级区块；当用户操作搜索指针继续向左移动，经过上述障碍操作之后，第一层的搜索指针移动至第49块，第二层的搜索指针移动至从左往右数的第60个二级区块。
参见图15和图16，在图15中，第二层波形搜索条中突出显示的是第17个二级区块(T2所示位置)，第三层波形搜索条中突出显示的是第1个三级区块(T31所示位置)，用户继续向左移动搜索指针，经过上述障碍操作之后，新的显示状态如图16所示，其中，第二层波形搜索条中突出显示的是第16个二级区块(T21所示位置)，第三层波形搜索条中突出显示的是最右侧的三级区块(T32所示位置)，即完成一次向左的跨边界操作。
进一步地，上述波形搜索方法中，如图9所示，将第一层波形搜索条按预设规则对待查找的所有波形进行划分而得到多个一级区块的具体步骤包括：
步骤S101、将第一层波形搜索条分成固定的多份，每一份代表一帧的数据；
步骤S102、按时间顺序依次检测每一帧是否含有触发波形；
步骤S103、将检测到有触发波形的帧作为一个单独的一级区块进行显示；
步骤S104、在检测到某一帧没有触发波形时，将其与下一相邻的帧合并；
步骤S105、判断是否合并到有触发波形的帧；
步骤S106、直到合并到有触发波形的帧后，将所有被合并的帧作为一个单独的一级区块进行显示。
例如，先检测第一帧是否含有触发波形，如果有，则作为一个单独的一级区块显示，然后检测第二帧是否含有触发波形，如果没有，则继续检测第三帧是否含有触发波形，如果仍然没有，继续检测第四帧是否含有触发波形，如果第四帧含有触发波形，则将第二帧、第三帧和第四帧一起作为第二个二级区块显示，如此按时间往后依次检测每一帧。采用该波形划分方法，可减少最终显示的一级区块数量，进一步节省用户的查找时间，提高查找效率。
进一步地，上述波形搜索方法中，对第二层波形搜索条、第三层波形搜索条和第四层波形搜索条进行区块划分的方法具体为：按照各层波形搜索条中波形的条数均匀分块。例如，第二层波形搜索条中包含10000条波形，则可将其分为100个二级区块，每个二级区块中包含100条波形。如此，对于每个二级区块对应的第三层波形搜索条中包含的100条波形，可继续等分，例如分成10个三级区块，每个三级区块中包含10条波形。如此可大大节省搜索时间，提高搜索效率。
上述各实施例中，第二层波形搜索条A2、第三层波形搜索条A3、第四层波形搜索条A4，可根据用户的指令来显示，也可以直接显示在搜索导航区。或者，可进一步显示第五层波形搜索条等。

上述波形搜索装置中，搜索条显示模块20还用于直接在搜索导航区显示第四层波形搜索条，或者在获取到用户输入的选择进一步查看某个三级区块的指令时，进一步在搜索导航区显示第四层波形搜索条；第四层波形搜索条包含：对第三层波形搜索条中被选择的三级区块中所包含的所有波形按预设规则进行进一步划分而得到的多个四级区块，所有四级区块中所包含的波形条数均等，并且总和等于被选择的三级区块中的波形条数；搜索指针模块30，还用于将搜索指针位置移至第四层波形搜索条；搜索条显示模块20，还用于突出显示当前搜索指针对应的四级区块；波形显示模块40，还用于在波形显示区中以重叠方式显示当前搜索指针对应的四级区块中所包含的一条或多条波形。
如图13所示，当前在搜索条导航区显示的是第一层波形搜索条A1和第二层波形搜索条A2、第三层波形搜索条A3、第四层波形搜索条A4，在波形显示区B中重叠显示的是第四层波形搜索条中T4指示的四级区块中包含的所有波形。当用户在第三层波形搜索条中找到目标异常波形所在三级区块后，可将待查看波形进行进一步的分层显示，以缩短查找时间，提高查找效率。
上述波形搜索装置中，如图18所示，波形显示模块40包括以两个状态交替显示的第一波形显示单元和第二波形显示单元；其中，第一波形显示单元41，用于以第一特征颜色重叠显示当前区块中的所有波形，同时以第二特征颜 色重叠显示当前层中除去当前块中波形之外的所有波形；第一波形显示单元42，用于隐藏第一状态中以第一特征颜色重叠显示的当前区块中的所有波形，而只以第二特征颜色重叠显示当前层中除去当前块中波形之外的所有波形；其中，当前区块为一级区块、二级区块、三级区块或四级区块，一级区块对应的当前层为第一层波形搜索条，二级区块对应的当前层为第二层波形搜索条，三级区块对应的当前层为第三层波形搜索条，四级区块对应的当前层为第四层波形搜索条。
通过采用上述第一状态和第二状态的交替显示，可更加快速的分辨出当前区块中是否包含待寻找的目标异常波形。如图14中，当隐藏当前区块中的波形后，剩余的波形中，目标特征消失，则说明需要寻找的特征波形仅包含在当前区块中，用户只需在当前区块中进一步查找即可，进一步提高了波形查找效率。
上述波形搜索装置中，如图19和图20所示，同时参阅图6，波形搜索装置进一步包括书签设置模块50，具体包括：书签检测单元51，用于在波形搜索模式下，实时检测用户是否输入书签设置指令；书签设置单元52，用于在获取到用户输入的书签设置指令时，记录波形显示区中当前显示的一条或多条波形对应的显示参数，显示参数包括时基信息、时延信息、当前块信息、当前层信息、波形颜色信息和触发设置信息；书签标记单元53，用于存储在一次书签设置指令下所记录的全部显示参数，并以一个书签标记按钮作为触发形式显示在数字示波器的人机交互界面中。
进一步地，上述波形搜索装置中，如图19和图21所示，同时参阅图7，波形搜索装置进一步包括波形回看模块60，具体包括：触发信息检测单元61，用于在波形搜索模式下，实时检测用户是否选择书签标记按钮；参数读取单元 62，用于在获取到用户选择书签标记按钮的触发信息时，读取所存储的该书签标记按钮对应的全部显示参数；书签波形显示单元63，用于将所读取的全部显示参数加载至当前波形显示系统，以将波形显示区的波形显示还原至书签标记时的状态。
这样使得用户在波形搜索模式下，可随时对当前查看的波形设置书签，以便于通过该书签功能随时回看感兴趣的波形区块，以免用户需要重新再次进行查找，节省了查找时间。
在进一步的波形搜索装置中，搜索条显示模块20还用于在获取到用户输入的选择退出查看当前层波形搜索条的指令时，在搜索导航区取消显示当前层波形搜索条；搜索指针模块30，还用于在取消显示当前层波形搜索条时，将搜索指针移回到上一层波形搜索条中当前被突出显示的区块。可方便用户从下一层波形搜索条退回至上一层波形搜索条，以进一步查看上一层波形搜索条中另一区块内的波形。
在进一步的波形搜索装置中，搜索指针模块30还包括：边界检测单元，用于实时检测搜索指针位置对应的区块是否为边界区块，边界区块包括：第二层波形搜索条的左侧边界区块或右侧边界区块、第三层波形搜索条的左侧边界区块或右侧边界区块、第四层波形搜索条的左侧边界区块或右侧边界区块；障碍设置单元，用于在搜索指针位置对应的区块为左侧边界区块，且获取到用户输入的向左调整搜索指针位置的调整信息时，暂不执行该次搜索指针位置调整指令，开始计数和计时，当计时满足预设时间后，看计数是否满足预设计数值，若否，则取消该次搜索指针位置调整指令，若是，则将搜索指针位置调整至当前左侧边界区块对应的上一层波形搜索条中当前突出显示区块的左侧区块位置；或者，在搜索指针位置对应的区块为右侧边界区块，且获取到用户输入的 向右调整搜索指针位置的调整信息时，暂不执行该次搜索指针位置调整指令，开始计数和计时，当计时满足预设时间后，看计数是否满足预设计数值，若否，则取消该次搜索指针位置调整指令，若是，则将搜索指针位置调整至当前右侧边界区块对应的上一层波形搜索条中当前突出显示区块的右侧区块位置。
采用上述方案，当用户需要跨边界操作搜索指针时，会遇到上述故意设置的操作障碍，以便于提醒用户该操作将同时改变上一层的搜索指针位置和当前层的搜索指针位置，增强操作感，防止误操作。
例如，第二层波形搜索模块有80个一级区块，当前突出显示的是第40个一级区块；第三层波形搜索模块有60个二级区块，当前突出显示的是从左往右数的第60个三级区块；当用户操作搜索指针继续向右移动，经过上述障碍操作之后，第二层的搜索指针移动至第41块，第三层的搜索指针移动至从左往右数的第1个三级区块。向左侧跨边界操作的例子可参见图15和图16，及前述方法实施例部分的描述。
在进一步的波形搜索装置中，搜索条显示模块20包括：划分单元，用于将第一层波形搜索条分成固定的多份，每一份代表一帧的数据；波形检测单元，用于按时间顺序依次检测每一帧是否含有触发波形；分区显示单元，用于将检测到有触发波形的帧作为一个单独的一级区块进行显示，在检测到某一帧没有触发波形时，将其与下一相邻的帧合并，直到合并到有触发波形的帧后，将所有被合并的帧作为一个单独的一级区块进行显示。
例如，先检测第一帧是否含有触发波形，如果没有，则继续检测第二帧是否含有触发波形，如果仍然没有，则继续检测第三帧是否含有触发波形，如果仍然没有，继续检测第四帧是否含有触发波形，如果第四帧含有触发波形，则将第二帧、第三帧和第四帧一起作为第一个二级区块显示，如此按时间往后依 次检测每一帧。采用该波形划分方法，可减少最终显示的一级区块数量，进一步节省用户的查找时间，提高查找效率。
在本发明的另一实施例中，还提供了一种数字示波器，其中包括前述任一实施例中的波形搜索装置，或者采用前述任一项的波形搜索方法进行波形搜索或查找。经实践证明，采用本实施例的数字示波器，可对数千条、数万条、甚至数十万条波形进行初步的一级区块划分，每个一级区块对应包含一条或者多条波形数据，并以波形搜索条的形式进行区块显示，方便用户进行分区查找，同时在波形搜索区以重叠的方式对当前搜索指针对应的一级区块中包含的所有波形进行显示，用户可直接看到当前搜索指针对应的一级区块中是否有异常波形，如果有异常波形，用户可进一步进行第二层波形搜索条，查看当前一级区块内的所有波形，而在第二层波形搜索条中，再进一步将所包含的波形进行二级区块的划分，并在波形显示区重叠显示当前搜索指针对应的二级区块中的所有波形，使得异常波形所在位置更加容易查找。或者，进一步对二级区块的波形进行进一步的分层划分区块，以进一步提高波形查找效率。
应当理解的是，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本发明所附权利要求的保护范围。
