Description

对待检测物质进行拉曼检测的方法和终端 技术领域
本公开涉及拉曼检测领域，尤其涉及一种对待检测物质进行拉曼检测的方法和终端。
背景技术
目前，拉曼检测技术普遍用于检测待检测物质的成分。拉曼检测中，让激光照射在待检测物质上，利用在激光作用下待检测物质发出的拉曼信号来检测各成分和各成分占比。对于液体来说，拉曼检测不但能准确检测待检测物质的成分，还能准确检测各成分占比。这是因为，对于液体来说，由于液体是流动的，可以达到分子间的充分混合，因此激光焦点照射范围内已经包含了无数多个充分混合的不同物质分子，因此占比分析是准确的。而对于粉末状固体物质来说，各成分混合无法达到绝对的均匀。即使粉末能够达到宏观的充分混合，但因为粉末的单颗直径比起激光焦点来说依然较大，也就使得每次检测过程中激光照射范围内的各成分比例都不同，所以输出结果都不同，无法充分反映出待检测物质的真实混合比例。而且，如果激光焦点只照射到一个颗粒上，则检测结果会输出为单种物质而非混合物，更不用说各成分比例了。因此，需要一种技术来解决拉曼检测检测粉末状物质时各成分占比检测不精确的问题。
应当理解的是，以上的一般描述仅是对相关技术的示例性解释，并不表示属于本公开的现有技术。

SP/f<a，                              ——公式1
其中a是预设常量。
根据本公开实施例的第二方面，提供了一种对待检测物质进行拉曼检测的终端，包括：
放置待检测物质的检测头；
发出用于拉曼检测的激光的激光光路；
震动马达，在所述待检测物质是粉末状物质的情况下，在拉曼检测中，带动所述待检测物质相对于所述激光光路震动。
在一个示例性实施例中，所述终端还包括：图像识别设备，用于拍摄所述待检测物质的图像，并从拍摄的图像中识别出所述待检测物质为粉末状物质。
在一个示例性实施例中，所述图像识别设备还从拍摄的图像中识别所述待检测物质的颗粒大小。所述终端还包括：处理器，用于基于识别出的颗粒大小，确定所述震动马达的震动频率。
在一个示例性实施例中，震动马达安装在所述检测头上，从而在拉曼检测中，震动马达带动所述待检测物质震动。
在一个示例性实施例中，震动马达安装在所述激光光路上，从而在拉曼检测中，震动马达带动所述激光光路震动。
在一个示例性实施例中，震动马达安装在封装所述激光光路的检测主体的壁上，从而在拉曼检测中，震动马达带动所述待检测物质和所述激光光路震动。

SP/f<a，                              ——公式1
其中a是预设常量。
本公开的实施例提供的技术方案可以包括以下有益效果：
本公开的一种实施例中，如果待检测物质是粉末状物质，在拉曼检测中，用震动马达带动粉末状物质相对于激光光路震动。因此，尽管激光照射在待检测物质上的区域有限，但由于这种震动，使得待检测物质的其它区域的颗粒随着这种震动进入激光照射的区域，让激光焦点的照射范围内包含了更多不同成分的颗粒。这样，就能够更精确地检测待检测物质的不同成分的占比，从而克服了静态检测中，进入激光照射在待检测物质上的区域的颗粒太少，检测精确性低的问题。
本公开的其他特性和优点将通过下面的详细描述变得显然，或部分地通过本公开的实践而习得。

具体实施方式
下面将参考若干示例性实施方式来描述本公开的原理和精神。应当理解，给出这些实施方式仅仅是为了使本领域技术人员能够更好地理解进而实现本公开，而并非以任何方式限制本公开的范围。相反，提供这些实施方式是为了使本公开更加透彻和完整，并且能够将本公开的范围完整地传达给本领域的技术人员。
本领域技术人员知道，本公开的实施方式可以实现为一种系统、装置、设备、方法或计算机程序产品。因此，本公开可以具体实现为以下形式，即：完全的硬件、完全的软件(包括固件、驻留软件、微代码等)，或者硬件和软件结合的形式。
根据本公开的实施方式，提出了一种对待检测物质进行拉曼检测的方法和终端。
下面参考本公开的若干代表性实施方式，详细阐释本公开的原理和精神。
如图1所示，根据本公开的一个实施例，提供了一种对待检测物质进行拉曼检测的方法，包括：
步骤S110：确定所述待检测物质是粉末状物质；
步骤S120：获取用于对待检测物质进行震动的震动马达的震动频率；
步骤S130：按照所述震动频率，在拉曼检测中，使震动马达带动粉末状物质相对于激光光路震动，所述激光光路用于发出用于拉曼检测的激光。
在对这些步骤进行详细描述之前，如图2A-4B所示，先对实现上述方法的终端的结构进行简要描述。
在一个实施例中，如图2A-4B所示，对待检测物质进行拉曼检测的终端包括检测头2和检测主体1。检测主体1具有发出用于拉曼检测的激光的激光光路11和用于感测待检测物质发出的拉曼信号强度的拉曼信号传感器12。将待检测物质放置到试剂瓶21后，置于检测头2上。激光光路11向待检测物质发出激光。在激光的作用下，待检测物质发出拉曼信号。拉曼信号传感器12感测待检测物质发出的拉曼信号强度，转换成电信号发送给处理器14进行分析。处理器14根据拉曼光谱以及可能还需要的其它检测参数，调用匹配算法确定待检测物质的成分及成分占比，发送到显示器15进行显示。检测头2和检测主体1通过连杆3连接。震动马达4设置在终端中。在拉曼检测中，震动马达4带动待检测物质相对激光光路11的震动，所述激光光路11用于发出用于拉曼检测的激光。
虽然图2A-4B示出了实现本公开的一个实施例的方法的终端的具体实现结构。但是，本领域技术人员应当理解，本公开不局限于这些具体结构。例如，虽然在图2A-4B中，将待检测物质放置到试剂瓶21后，置于检测头2上，本领域技术人员应当理解，待检测物质也可以直接放置在检测头2上。虽然在上述图中，激光光路11、拉曼信号传感器12、显示器15放置在检测主体1内部，应当理解，它们也可以放置在检测主体1外部。而且，在某些实施例中，检测主体1是可以打开的，并且可以将检测头2也放置在检测主体1内部并与激光光路11保持一定距离。在一些实施例中，也可以不采用拉曼信号传感器12感测待检测物质发出的拉曼信号强度，而是用本领域已知的其它方法获得待检测物质发出的拉曼信号强度。显示器15根据需要也可以替换成播放器，用于将拉曼检测结果语音播报而不是显示出来。另外，检测头2与检测主体1之间也不一定需要连杆3连接。例如，检测头2与检测主体1可以直接连接，只要检测头2与激光光路11保持一定距离。或者，检测头2月检测主体1也可以是独立的，其中检测主体1在激光光路11向外发激光的位 置设置透明窗口，以保证激光光路11发出的激光能照射到待检测物质。但在这种情况下，要人工使检测头2放置在距离该透明窗口一定距离的前方，从而保证待检测物质基本位于激光光路的焦点附近。
下面，对步骤S110-S130分别详细描述。
在步骤S110中，确定所述待检测物质是粉末状物质。
在一个实施例中，步骤S110可以通过检测在输入接口16的输入的方式实现。如图2A-4B所示，在检测主体1设置输入接口16，例如触摸屏。用户自行判断待检测物质是粉末状物质，然后在输入接口16上进行输入，例如触摸触摸屏上“粉末状物质”的选项。基于检测到的输入接口16上的用户输入，来确定所述待检测物质是粉末状物质。在图2A-4B所示的例子中，步骤S110可以由处理器实现。
上述实施例中，判断所述待检测物质是粉末状物质需要用户进行输入。为了提高待检测物质检测的自动化程度，在一个实施例中，如图6所示，步骤S110具体包括：
S1101、拍摄所述待检测物质的图像；
S1102、从拍摄的图像中识别出所述待检测物质为粉末状物质。
目前，拍摄物品的图像并从图像中识别出物品的性质，可以通过现有的图像识别技术来完成。在图2A-4B所示的例子中，步骤S1101和步骤S1102可以由图像识别设备13来实现。图像识别设备13识别出所述待检测物质为粉末状物质后，发消息通知处理器14。该实施例通过图像识别设备自动判断所述待检测物质是粉末状物质，克服了人工操作带来的检测效率低的问题。
在步骤S120中，获取用于对待检测物质进行震动的震动马达的震动频率。
在一个实施例中，步骤S120通过检测用户在输入接口16输入的震动马达的震动频率进行。由用户根据经验，估计对待检测物质进行拉曼检测所需要的震动马达的震动频率。然后，用户将估计的震动频率通过输入接口16输入。输入接口16将输入的震动频率发送到处理器14。处理器就得到了用于对待检测物质进行震动的震动马达的震动频率。
在另一个实施例中，步骤S120通过检测用户在输入接口16输入的待检测物质的颗粒大小，并根据输入的颗粒大小确定所需要的震动马达的震动频率。事先在处理器14存储颗粒大小与震动马达的震动频率对照表或对应关系公式。根据输入的颗粒大小确定所需要的震动马达的震动频率可以通过根据输入的颗粒大小查找所述对照表或对应关系公式进行。另外，该对照表或对应关系公式也可以不存储在处理器14，而是存储在处理器14外部的存储器(未示)中，该存储器可以在检测接口1内部，也可以在检测接口1外部。
在一个实施例中，待检测物质的颗粒大小可以用预先规定的颗粒大小级别表示。将待检测物质的颗粒大小分为几个级别。从肉眼可以观察到待检测物质的颗粒大小，并判断该颗粒大小所述的级别。然后，用户将判断出的级别输入到输入接口16。
为了提高确定震动马达的震动频率的精度，从而提高待检测物质的检测精确性，在一个实施例中，如图7所示，步骤S120包括：
S1201：拍摄所述待检测物质的图像；
S1202：从拍摄的图像中识别所述待检测物质的颗粒大小；
S1203：基于识别出的颗粒大小，确定所述震动马达的震动频率。
在图2A-4B所示的例子中，步骤S1201、步骤1202是由图像识别设备13执行的。步骤S1203可以通过由处理器14查找颗粒大小与震动马达的震动频率对照表或对应关系公式的方式执行。可以事先在处理器14存储颗粒大小与震动马达的震动频率对照表或对应关系公式。根据步骤S1202中识别出的颗粒大小，查找预先存储的对照表或对应关系公式，可以得到所述震动马达的震动频率。另外，该对照表或对应关系公式也可以不存储在处理器14，而是存储在处理器14外部的存储器(未示)中，该存储器可以在检测接口1内部，也可以在检测接口1外部。该实施例通过图像识别的方式识别待检测物质的颗粒大小，并基于识别出的颗粒大小，确定所述震动马达的震动频率。其相对于人工输入颗粒大小的方式，提高了判断颗粒大小的精确性。另外，步骤S1201-S1203完全由机器自动完成，提高了检测待检测物质的自动化程度。
步骤S130：按照所述震动频率，在拉曼检测中，使震动马达带动粉末状物质相对于激光光路震动。带动粉末状物质相对于激光光路震动包括带动粉末状物质震动和/或带动激光光路震动。
在一个实施例中，步骤S130包括：如图2A-2B所示，使震动马达4安装在放置所述待检测物质的检测头2上，从而在拉曼检测中，震动马达4带动所述待检测物质震动。
在该实施例中，待检测物质震动，激光光路11不震动。因此，尽管激光照射在待检测物质上的区域有限，但由于这种震动，使得待检测物质的其它区域的颗粒随着这种震动进入激光照射的区域，达到了颗粒的充分混合，让激光焦点的照射范围内包含了更多不同成分的颗粒。这样，就能够更精确地检测待检测物质的不同成分的占比，提高检测精确性。
该实施例的优点在于，震动马达4的震动可以使颗粒的混合更均匀，检测精度高。
在一个实施例中，步骤S130包括：如图3A-3B所示，使震动马达4安装在所述激光光路11上，从而在拉曼检测中，使震动马达带动所述激光光路11震动。
在该实施例中，待检测物质不震动，激光光路11震动。激光光路11不震动时焦点照射在待检测物质上的区域是比较小的区域，但在激光光路11震动时该焦点在待检测物质上不断移动，就使得待检测物质的其它区域的颗粒随着这种震动进入激光照射的区域，让激光焦点的照射范围内包含了更多不同成分的颗粒。这样，就能够更精确地检测待检测物质的不同成分的占比，提高检测精确性。
该实施例的优点在于，震动马达4可以位于检测主体1的内部，不容易受到损坏。
在一个实施例中，步骤S130包括：如图4A-4B所示，使震动马达安装在用于对待检测物质进行拉曼检测的检测主体的壁上，从而在拉曼检测中，使震动马达带动所述待检测物质和所述激光光路震动。
该实施例的优点在于，震动马达4容易安装。
如图5所示，在一个实施例中，该方法还包括S140：调节震动马达的震动频率f和/或向待检测物质照射的激光功率P，使得待检测物质在单位激光功率激发下发出的拉曼信号强度S、震动马达的震动频率f、向待检测物质照射的激光功率P之间满足以下关系：
SP/f<a，                              ——公式1
其中a是预设常量。
如果待检测物质发出的拉曼信号强度很高，这时在待检测物质的检测过程中的预判检测的时间可能过短，造成激光不能充分地照射在待检测物质的尽可能多的颗粒上。这时，如果震动马达的震动频率比较高，就可以让激光在单位时间内更多次往复地照射在待检测物质上，就能够照射到更多颗粒，从而弥补待检测物质发出的拉曼信号强度过强造成的检测精度降低。如果向待检测物质照射的激光功率比较低，也可以弥补这一不足。这是因为，如果向待检测物质照射的激光功率比较低，拉曼信号就会相应减弱，就可以延长积分时间，增加震动的次数，使检测结果更加准确。但是，如果待检测物质发出的拉曼信号强度很高，震动马达的震动频率也较低，并且向待检测物质照射的激光功率也较高，则不能成功弥补上述不足。因此，利用公式1可以考察上述三种因素的关系是否能够达到可接受的检测精度。由于待检测物质单位激光功率发出的拉曼信号强度是不能调节的，是物质自身的特性，只能通过调节震动马达的震动频率和/或向待检测物质照射的激光功率，来使公式1成立。
该实施例的优点是，能够在对待检测物质的检测过程中，在某些特殊原因导致检测精确性降低的情况下，对检测过程进行控制，提高检测精确性。
一般来说，待检测物质在单位激光功率激发下发出的拉曼信号强度S是由待检测物质本身的性质决定的，是不变的。因此，如果公式1不满足，要么调节震动马达的震动频率f，要么调节向待检测物质照射的激光功率P，要么二者都调节。
在只调节震动马达的震动频率f的情况下，认为向待检测物质照射的激光功率P不变，则调节震动马达的震动频率f，使得：
f>SP/a                             ——公式2。
在只调节向待检测物质照射的激光功率P的情况下，认为调节震动马达的震动频率f不变，则调节向待检测物质照射的激光功率P，使得：
P<fa/S                             ——公式3。
