Description

一种光学检测设备及检测方法 技术领域
本申请涉及光学检测技术领域，尤其涉及一种光学检测设备及检测方法。
 背景技术
当前专业光学物质检测设备，多是接触式的检测，如拉曼光谱仪等，由于光学检测设备上透镜的焦点是固定的，激光有一个固定的焦距，因此，只要将物质放置在焦点位置即可进行检测。但是，由于用户自身操作手持不稳，或者对焦点的把控不到位，使得物质的检测结果受到较大影响。所以，目前很多的检测设备采用一个凸起探头的结构，使光学焦点恰好位于凸起探头的最前端，也就是将待测物质抵在探头上时，物质正好位于焦点位置。
 技术问题
发明人在研究现有技术的过程中发现，现有的光学检测设备上的凸起结构能够使得物质正好位于光学焦点位置，然而，未经过培训的使用者或首次使用的测试人员依然在很多时候不能将物质准确放置在焦点位置，另外，物质还未处于焦点位置时，先选择了检测激光发射，然后才将物质移动到焦点位置，或者检测尚未结束就将物质移开等都可能造成检测信噪比降低甚至检测错误的情况发生。
因此，需要避免上述不能准确放置物质的情况和检测异常状况的发生。
 技术解决方案
本申请部分实施例所要解决的技术问题在于提供一种光学检测设备及检测方法，用以解决使用光学检测设备检测物质的过程中不能准确放置待检测的物质的情况。
本申请的一个实施例提供了一种光学检测设备，包括：设备主体、检测探头和压力传感器，压力传感器设置在检测探头上，检测探头对准设备主体的光线出入口，压力传感器与设备主体建立通信连接；压力传感器，用于检测检测探头承受的压力值，并将压力值传输给设备主体；设备主体，用于获取压力传感器传输的压力值，根据压力值判断是否有放置的待检测物，并在确定有放置的待检测物后启动检测过程。
本申请的一个实施例还提供了一种检测方法，应用于上述实施例中的光学检测设备，包括：压力传感器将检测的检测探头承受的压力值传输到设备主体；设备主体根据压力值判断是否有放置的待检测物；设备主体确定有放置的待检测物后启动检测过程。
 有益效果
相对于现有技术而言，本申请部分实施例中在检测探头上设置压力传感器，使设备主体能够通过压力传感器传输的压力值实时了解检测探头上是否有放置的待检测物，且在确定有放置的待检测物之后开始检测，避免了因人为因素放置待检测物位置不准确影响检测结果的现象发生，另外，通过设置压力传感器，设备主体能够根据压力值判断待检测物放置的状况，不需要用户根据使用经验去放置待检测物，由此，即使是未经过培训的使用者或第一次使用的人也能够快速简单的使用该光学检测设备，提高了用户的操作体验。

 本发明的实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请部分实施例进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。然而，本领域的普通技术人员可以理解，在本申请的各实施例中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施例的种种变化和修改，也可以实现本申请所要求保护的技术方案。
本申请的第一实施例涉及一种光学检测设备，包括：设备主体10、检测探头20和压力传感器30，如图1所示，压力传感器30设置在检测探头20上，检测探头20对准设备主体10的光线出入口（图中未示出），压力传感器30与设备主体10建立通信连接；
压力传感器30，用于检测检测探头20承受的压力值，并将压力值传输给设备主体10；设备主体10，用于获取压力传感器30传输的压力值，根据压力值判断是否有放置的待检测物，并在确定有放置的待检测物后启动检测过程。
具体的，检测探头20用于与待检测物接触的位置设有凸起部；其中，压力传感器30用于检测凸起部承受的压力值。需要说明的是，在启动光学检测设备检测待检测物时，需预先将待检测物放置在检测探头的焦点位置，才能够使得光学检测设备能够准确的对待检测物进行检测，使得收集获取的待检测物光谱更准确、检测结果更可靠，也就是说，压力传感器用于检测凸起部承受的压力值，使设备主体在检测时能够根据压力传感器传输的压力值确保待检测物放置于焦点位置，提升了检测设备的智能性。
值得一提的是，本实施例中仅是以检测探头顶端即为焦点位置的接触式光学检测设备为例进行说明，对于非接触式光学检测设备，可以将压力传感器设置于焦点位置处的其他部件上，只要在放置待检测物时，使得压力传感器能够感知到压力变化即可。
一个具体实现中，设置于凸起部的压力传感器为环形压力传感器，则在检测探头20上设置转换电路，转换电路与压力传感器30电连接，且与设备主体10通信连接；转换电路将压力传感器30输出的信号转换为电压值，并传输电压值到设备主体10。
需要说明的是，由于环形压力传感器的结构能够很好的贴合于凸起部，且能够准确检测凸起部环形部分的压力分布，根据环形压力传感器的结构特征，需要在检测探头上设置匹配环形压力传感器的转换电路，使设备主体能够根据环形压力传感器传输的压力值了解到检测探头上环形部分的压力分布，进而了解到待检测物是否放置于焦点位置。
值得一提的是，在检测探头的凸起部还可设置其他类型的压力传感器，如半导体压力传感器，因设置不同的压力传感器需要设计不同的转换电路，上述仅是举例说明，并不限制设置于凸起部的压力传感器类型和转换电路的结构。
具体的，在检测的过程中，设备主体10确定有放置的待检测物的过程为：判断压力值是否大于或等于预设门限值，若是，则确定有放置的待检测物。
需要说明的是，可以更新实际检测的需要设置预设门限值的取值，由于不同的待检测物的质量不同对应的预设门限值也可能不同，例如，检测质量较轻的待检测物时，可将预设门限值设为2，压力传感器检测到凸起部的压力值大于2，设备主体根据不为2的压力值可确定检测探头上有放置待检测物；检测质量较重的待检测物，如金属等，可将预设门限值设为5，压力传感器检测到凸起部的压力值大于5，设备主体可根据压力值确定检测探头上有放置待检测物。此处仅为举例说明，具体不限制预设门限值的取值。
具体的，在开始检测之后，可通过预设信噪比或检测时长确定检测是否结束，如检测开始后获取待检测物的光谱数据，并计算信噪比，当计算获得的信噪比小于或等于预设信噪比时，则说明检测过程完成；或者，在检测开始之后记录检测的时间，当检测时间大于或等于预设的检测时长，则说明检测过程完成。确定检测过程完成不限于上述提到的方式，此处仅为举例说明。
值得一提的是，在检测开始之后，检测尚未完成时，若压力传感器检测到检测探头承受的压力值减小，为避免影响检测结果，设备主体用于：在确定获取到的压力值从大于或等于预设门限值变化为小于预设门限值时，保存已获得的光谱数据或记录的检测时长，并发出检测尚未完成的提示；若在预设时长内确定获取到压力值大于或等于预设门限值，则提取已获得的光谱数据继续进行检测。
一个具体的实现中，若检测过程是多次收集待检测物的光谱数据，则有检测中断发生时，保存当前已获取的光谱数据，在后续确定继续检测之后，若有必要可选择丢弃最后一次的收集的光谱数据，并继续收集待检测物的光谱数据，直到确定收集物质光谱的次数满足检测物质光谱的次数要求，则说明检测完成。
需要说明的是，最后一次收集的光谱数据由于检测中断导致光谱数据不完整，为了保证检测结果的准确性，将最后一次收集的光谱数据丢弃，并在继续检测之后对收集光谱的次数增加一次，以保证能够得到完整的待检测物的光谱数据。
值得一提的是，光谱数据至少包括物质光谱和反射光谱中的一个。
另一个具体实现中，根据检测时长确定是否完成检测，若有检测中断的情况发生，检测计时也暂停，后续恢复检测后继续计时，直至检测时长达到预设的检测时长，则确定检测结束。
需要说明的是，具体判断检测结束的依据并不局限于上述提到的检测时长或预设信噪比，在检测过程中若发生因待检测物位置变化而中断检测的，恢复检测后确定检测结束的依据取决于具体的物质光谱数据收集策略，此处不做限制。
相对于现有技术而言，在检测探头上设置压力传感器，使设备主体能够通过压力传感器传输的压力值实时了解检测探头上是否有放置的待检测物，且在确定有放置的待检测物之后开始检测，避免了因人为因素放置待检测物位置不准确影响检测结果的现象发生，另外，通过设置压力传感器，使得设备主体能够根据压力值判断待检测物放置的状况，不需要用户根据使用经验去放置待检测物，由此，即使是未经过培训的使用者或第一次使用的人也能够快速简单的使用该光学检测设备，提高了用户的操作体验。
本申请的第二实施例涉及一种光学检测设备，第二实施例与第一实施例大致相同，主要区别之处在于，在第二实施例中压力传感器的设置位置发生了改变，其结构如图2所示。
将压力传感器30设置于检测探头20与设备主体10的连接处，压力传感器30可用于检测整个检测探头20承受的总的压力值。需要说明的是，由于压力传感器30设置于检测探头20与设备主体10的连接处，不能具体确定检测探头20某一点的压力值，但是，压力传感器30能够根据压力值确定是否有待检测物与检测探头接触。
由于检测探头20凸起部的顶端即为镜头焦点位置，将待检测物放置于凸起部的前端，设备主体10即能够根据压力传感器30检测到的压力值确定是否有待检测物放置在焦点位置。
需要说明的是，该检测探头还可以在其他的位置设置压力传感器，只要能够获取到检测探头承受的压力值即可，此处不限制压力传感器设置的具***置。
值得一提的是，若在检测探头与设备主体的连接处设置压力传感器，例如，单颗的压力传感器，由于该压力传感器直接能够将获取的压力值反馈给设备主体，不需要设计转换电路，检测探头可以为一个简单金属件或塑料件，结构简单。
相对于现有技术而言，在检测探头和设备主体的连接处设置压力传感器，使得检测探头上不需要设计额外的电路，简化了检测探头的结构，降低了成本。
以上各实施例中，有放置的待检测物，是指待检测物放置在焦点位置。其中，对于接触式光学检测设备，是指待检测物放置在检测探头的前端的焦点位置，若压力传感器设置在检测探头的前端，则待检测物与压力传感器直接接触，否则，待检测物与检测探头的前端直接接触。
本申请的第三实施例涉及一种检测方法，应用于上述第一或第二实施例所涉及的光学检测设备，具体实施流程如图3所示，包括：
步骤301：压力传感器将检测的检测探头承受的压力值传输到设备主体。
一个具体实现中，若压力传感器设置于检测探头的凸起部，则需要设置转换电路，转换电路将压力传感器输出的信号转换为电压值；转换电路将电压值传输到设备主体。
需要说明的是，对于不需要设置转换电路的压力传感器，该压力传感器直接将获取到的压力值传输到设备主体即可，转换电路可依据压力传感器的类型进行设置和调整，此处不做限制。
步骤302：设备主体根据压力值判断是否有放置的待检测物。
具体的，设备主体判断压力值是否大于或等于预设门限值；若是，设备主体确定有放置的待检测物。
步骤303：设备主体确定有放置的待检测物后启动检测过程。
不难发现，本实施方式为与第一实施方式相对应的方法实施例，本实施方式可与第一实施方式互相配合实施。第一实施方式中提到的相关技术细节在本实施方式中依然有效，为了减少重复，这里不再赘述。相应地，本实施方式中提到的相关技术细节也可应用在第一实施方式中。
本申请的第四实施例涉及一种检测方法，第四实施例与第三实施例大致相同，主要区别在于，在本实施例中还包括检测过程中发生检测中断的处理方式，具体如图4所示。
需要说明的是，可能发生的检测中断是在检测过程开始之后，也就是第三实施例步骤303之后，因而本实施例中对于步骤301至步骤303就不再赘述，仅说明步骤303之后增加的步骤。
步骤401：若设备主体确定获取到压力值从大于或等于预设门限值变化为小于预设门限值。
步骤402：设备主体保存已获得的光谱数据或记录的检测时长并发出检测尚未完成的提示。
步骤403：若设备主体在预设时长内确定获取到力值大于或等于预设门限值。
步骤404：设备主体提取已获得的光谱数据继续进行检测。
本实施例是与上述光学检测装置对应的方法的实施例，在上述实施例中提到的技术细节在本实施例中依然适用，此处不再赘述。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
本申请的第五实施例涉及一种计算机可读存储介质，该可读存储介质为计算机可读存储介质，该计算机可读存储介质中存储有计算机指令，该计算机指令使计算机能够执行本申请第三或第四方法实施例中涉及的检测方法。
需要说明的是，本领域的技术人员能够理解，上述实施例中显示方法是通过程序来指令相关的硬件来完成的，该程序存储在一个存储介质中，包括若干指令用以使得一个设备（可以是单片机，芯片等）或处理器（processor）执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器（ROM，Read-Only Memory）、随机存取存储器（RAM，Random-Access Memory）、磁碟或者光盘等各种可以存储程序代码的介质。
本领域的普通技术人员可以理解，上述各实施例是实现本申请的具体实施例，而在实际应用中，可以在形式上和细节上对其作各种改变，而不偏离本申请的精神和范围。
