紫外线是指波长为100-400nm的太阳辐射的总称。紫外线强度的大小与人们生活息息相关。当太阳中的紫外线强度过大时，可能会对人体的皮肤、眼睛等组织或器官造成损伤。比如，强度较大的紫外线可能会引发皮肤癌、白内障等疾病，或者会使得人体的免疫系统的免疫能力降低。但是，适量的紫外线照射有助于人体合成维生素D，促进人体对钙的吸收。因此，如何防止紫外线过度照射，引起了人们的广泛关注。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明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仅用以解释本发明，并不用于限定本发明。
本发明实施例的目的在于提供一种紫外线强度检测方法，以解决现有技术 中对于紫外线强度进行检测时，通常由专用的紫外线强度检测仪进行检测，这种检测方式需要购买昂贵的检测设备，而且紫外线强度检测仪携带较为不便，不利于用户随时随地进行紫外线强度检测。为了提高检测的便利性，现有技术可以使用移动终端进行紫外线强度的查看，通过查看气象服务台发布的紫外线强度，提高了用户使用的便利性，但是这种紫外线强度数据是针对某个区域的紫外线强度，使得用户获取的紫外线强度的精度不高。下面结合附图，对本发明作进一步的说明。
实施例一：
图1示出了本发明第一实施例提供的紫外线强度检测方法的实现流程，详述如下：
在步骤S101中，获取当前的时间和日期、用户终端当前的位置以及获取用户终端当前位置对应的云层数据。
具体的，本发明实施例中
本发明实施例所述当前的时间，是指在一天24小时中的一个时间点。比如，所述当前的时间可以为中午12点20分18秒。所述时间的精度可以根据用户的精度需要，保留或者略去时间中的秒值部分的数据。比如，用户在对精度要求一般的情况下，可以直接使用时间12点20分。所述时间的获取，可以直接读取用户终端的本地时间，也可以向网络时间服务器发送网络时间获取请求，得到网络服务器返回的精准时间。
所述当前的日期，是指在一年365天中具体处于哪一天。可以采用“月份”和“日”相结合的方式表示日期，比如可以用“6月22日”表示具体的日期。同样，所述日期的获取可以直接读取用户终端的本地日期，也可以向网络时间服务器发送网络时间获取请求，得到网络服务器所返回的准确的日期。
所述用户终端当前的位置，可以通过卫星定位的方式获取，也可以通过移动信号的基站定位的方式获取，或者还可以根据WIFI接入点定位。可以根据用户终端的场景需要，智能的选择定位的方式。比如高楼林立的室外场景，卫星 定位信号可能不是特别强，可以通过移动基站进行定位，或者根据WIFI接入点进行定位。
所述用户终端当前位置对应的云层数据，是指用户终端的位置与太阳的位置之间的云层数据，所述云层数据的大小，可以影响紫外线强度。当云层数据越大时，用户终端所在位置的紫外线强度越小，当云层数据越小时，用户终端所在位置的紫外线强度也越大。所述云层数据的获取，可以由用户根据当前的情景，接收用户输入的云层数据，也可以根据用户的位置，获取与所述位置对应的紫外线强度，或者还可以通过拍照的方式，获取所述云层数据。
所述云层数据可以包括云层的厚度，也可以包括云层的形状、亮度等。
所述用户终端可以为智能手机、平板电脑、笔记本电脑等。通过设置与本发明所采集的数据对应的传感电路，以及数据通信电路，结合数据处理模块，使得用户可以方便的使用其获取当前场景的紫外线强度数据。
另外，本发明在获取时间、日期、位置和云层数据之前，还可以包括对当前场景的亮度进行检测的步骤，当亮度小于预设的阈值时，则不进行上述数据的获取。只有亮度大于预设的阈值时，才进行上述数据的获取。通过这种智能控制方式，可以有效的节省用户终端的电能的同时，也可以使得用户终端的系统的资源利用更加优化。
在步骤S102中，根据当前的时间和日期以及用户终端当前的位置，在预设的数据库中查找用户当前时间和位置对应的第一紫外线强度。
具体的，在数据库中预先设置有一第紫外线强度序列，所述第一紫外线强度序列可以通过历史数据筛选的方式获取。比如可以设定在特定的云层数据条件下，得到不同时间和日期，在不同位置的紫外线强度。所述特定的云层数据条件，优选为无云的条件下对应的紫外线强度。所述数据库的获取，可以通过多年数据记录的方式获取(比如通过多年记录的方式，寻找在天气晴朗，没有云层的状态下所对应的紫外线强度)，也可以通过数据记录与合理预测相结合的方式，形成完整的第一紫外线强度查找的数据库。
当然，所述第一紫外线强度也可以为其它特定云层数据下所对应的紫外线强度，比如可以选定云层厚度为指定的一个标准状态，通过多次记录或者计算的方式，获取每个时间、日期，在不同位置所对应的第一紫外线强度。
当然，所述数据库的精度也可以在使用过程中不断的完善，比如可以将当前时间、日期和位置所对应的紫外线强度与气象服务站提供的紫外线强度进行比较。如果两者的差值明显过大，比如超过预先设定的紫外线差值，则可以向服务器发送提醒信息，确认当前的紫外线强度是否与实际相符。
在步骤S103中，根据预设的云层数据与修正系数的对应关系，查找所述获取的云层数据所对应的第一修正系数，根据所述第一修正系数和所述第一紫外线强度，生成第二紫外线强度。
在步骤S102中获取的第一紫外线强度，为特定云层数据下的紫外线强度，为了能够适应云层数据变化的特定，在步骤S103中还包括对云层数据作进一步的修正，从而使得用户终端当前的紫外线强度更加与场景相符。
通过预先设定云层数据与修正系数的对应关系，可以使得用户终端在不同场景下，由云层数据快速的查找对应的第一修正系数。所述云层数据可以包括云层的厚度、云层的形状、云层的颜色等属性。在查找所述云层数据对应的修正系统时，可直接根据云层数据的属性在数据库中查找。
当所述第一紫外线强度为无云场景下对应的紫外线强度时，所述第一修正系数为与所述第一紫外线强度相乘，且数值小于或等于1的系数。随着云层厚度的增加，或者随着云层面积的块状区域的面积加大，或者随着云层颜色的加深，所述第一修正系数逐渐变小，从而使得修正后的第二紫外线强度越小。
当所述第一紫外线强度为特定云层厚度、形状与颜色下的紫外线强度，那么，在其它场景下，所述第一修正系数可能大于1，比如在云层厚度变薄，或者颜色变浅，或者形状细块化的时候，或者也可能小于1，比如随着云层厚度的增加，或者随着云层面积的块状区域的面积加大，或者随着云层颜色的加深等。
另外，本发明还可以对紫外线强度的照射时长进行累计，对不同的紫外线强度设定不同的照射时间阈值，当用户终端处于某一紫外线强度下，照射的时长达到预定的阈值时，则发出提醒信息，提示用户注意紫外线可能会对人体造成伤害。
在获取到紫外线强度后，还可以进一步检测用户处于紫外线强度的场景下的持续时长。可以根据预先设定的紫外线强度与日照时长的对应关系，当用户在紫外线场景下的持续时长超过对应的日照时长时，则可以向用户发出提醒信息。进一步优化的实施方式中，可以预先获取用户的状态数据，根据所述状态数据生成相应的日照时长。所述状态数据可以包括用户的维生素D的含量，或者还可以包括用户的黄疸数据等。
由于本发明生成的第二紫外线强度是根据用户终端当前的时间、日期和位置所查找的第一紫外线强度，并且通过云层数据对第一紫外线强度所修正后的数据，因此，其数值与用户的当前场景更加相符，获取方便的同时，获取的紫外线强度的精度也会更高。
实施例二：
图2示出了本发明第二实施例提供的紫外线强度检测方法的实现流程，详述如下：
在步骤S201中，获取当前的时间和日期、用户终端当前的位置。
在步骤S202中，通过用户终端的摄像头获取太阳与用户之间的云层图像。
具体的，在一天中的不同时间点，所述太阳的位置也会不相同。并且在一年365天中的不同天的同一时间里(比如3月14日的上午11：30与9月12日的上午11：30)，所述太阳的位置也会不同。另外，在同一天的不同时间，太阳的位置也会不同。因此，所述通过用户终端的摄像头获取太阳与用户之间的云层图像步骤具体可以包括：
1.1、根据当前时间和日期，确定太阳所在的位置；
1.2、根据用户终端的运动传感器获取用户终端的状态，根据所述用户终端 的状态确定摄像头的偏转角度；
1.3、当所述摄像头的偏转角度与所述太阳的位置对应时，拍摄得到云层图像。
其中，所述太阳的位置，为相对于用户终端的位置，比如可以为用户头顶正上方，或者与正上方所成的偏转角。所述太阳所在的位置随着时间变化，可以预先设定指定的周期对所述太阳的位置进行采集，或者根据用户的位置，实时的计算当前时间和日期对应的太阳的位置。
所述用户终端可以包括运动传感器，用于检测用户终端的状态，比如用户终端为平放或者竖起放置的状态等。当所述用户终端有两个摄像头时，可以检测两个摄像头中的任意一个与所述太阳的位置对应时，即任意一个摄像头对准太阳的位置时，则向摄像头发送拍摄指令，由摄像头拍摄当前位置对准太阳的图像。由于该方法可通过摄像头自动的进行云层图像的拍摄，可以使得用户使用更加智能和人性化，提高检测的效率。
在步骤S203中，将获取的云层图像与预先设定的云层样本进行对比，获取所述云层图像对应的云层数据。
在获取到云层图像后，需要对云层图像进行识别，根据云层图像的特征，计算云层对紫外线的拦截效率，从而方便后续对第一紫外线强度进行优化。所述将获取的云层图像与预先设定的云层样本进行对比，获取所述云层图像对应的云层数据步骤包括：
将获取的云层图像的亮度值、云层图像的形状，与预先设定的云层亮度样本和形状样本比较；
根据比较的结果，获取所述云层图像对应的云层亮度样本和形状样本。
在所述云层图像的亮度值的比较时，可以通过关闭摄像头使用的自动曝光等调节功能，得到相机参数一致条件下所拍摄的图像。从而能够对不同时间拍摄的云层图像的亮度值进行有效的对比。
所述云层图像的亮度，可以反应所述云层的厚度。一般情况下，云层图像 的亮度越低，表示云层的厚度越厚，亮度越小，则云层的厚度越薄。
另外，所述云层图像中的云层面积，可以影响紫外线的穿透，当所述形状为较小块形状时，则紫外线穿透或者折射云层的能力越强，如果云层为大块云层时，则紫外线穿透或者折射云层的能力会减小。
通过预先设定的云层亮度样本和云层形状样本，与获取的云层图像进行对比，可查找当前获取的云层图像较为的云层亮度样本和云层的形状样本，即本发明所述的云层数据。根据预先设定的云层数据与修正系数的对应关系，可以查找所述云层数据对应的第一修正系数。
在步骤S204中，根据当前的时间和日期以及用户终端当前的位置，在预设的数据库中查找用户当前时间和位置对应的第一紫外线强度。
在步骤S205中，根据预设的云层数据与修正系数的对应关系，查找所述获取的云层数据所对应的第一修正系数，根据所述第一修正系数和所述第一紫外线强度，生成第二紫外线强度。
步骤S204-S205与实施例一中步骤S102-S103基本相同，在此不作重复赘述。
本发明实施例在实施例一的基础上，进一步介绍了对于云层图像的获取方式，通过智能的检测用户终端的状态，可以更为快捷有效的获取云层图像，并对所述云层图像进行智能的分析和对比，从而有利于用户更加方便有效的获取紫外线强度。
实施例三：
图3示出了本发明第三实施例提供的紫外线强度检测方法的实现流程，详述如下：
在步骤S301中，获取当前的时间和日期、用户终端当前的位置以及获取用户终端当前位置对应的云层数据。
在步骤S302中，根据当前的时间和日期以及用户终端当前的位置，在预设的数据库中查找用户当前时间和位置对应的第一紫外线强度。
在步骤S303中，根据预设的云层数据与修正系数的对应关系，查找所述获取的云层数据所对应的第一修正系数，根据所述第一修正系数和所述第一紫外线强度，生成第二紫外线强度。
步骤S301-S303与实施例一中步骤S101-S103基本相同，在此不作重复赘述。
在步骤S304中，根据当前时间和日期，确定太阳所在的位置；
在步骤S305中，获取用户终端当前所在位置与太阳所在位置之间的臭氧浓度，根据所述臭氧浓度查找对应的第二修正系数，根据所述第二修正系数对所述第二紫外线强度进行修正。
所述臭氧浓度，可以将用户与太阳之间的位置发送至臭氧监测服务器，通过检测太阳与用户终端之间的臭氧浓度，可以对用户终端所在位置的紫外线强度进一步修正。可以通过历史统计的数据确定所述臭氧浓度与修正系数的对应关系。
除此之外，还可以获取用户终端所在场景的能见度、湿度等数据。通过采集能见度、湿度等数据，结合历史统计的数据确定不同能见度、不同湿度所对应的修正系数，从而更进一步对用户终端所在场景的紫外线强度进行修正。进一步提高紫外线强度检测的精度。
