Description

本申请涉及温湿度测量技术领域，尤其涉及一种温度测量方法及装置。
背景技术
体温是度量人体冷热的物理量，实际应用中大多是通过温度计测量皮肤表面的温度。不同部位的皮肤表面情况差异较大，大部分受测皮肤表面在测量时裸露在空气中，受环境影响较大，测量结果的准确度较低。而位于相对较为封闭的空间中的皮肤表面如腋下、口腔等，与人体温度的关系相对稳定，所以，腋下、口腔等部位成为体温测量的标准位置。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在连续温度测量的应用场景中，包括侵入式温度测量和非侵入式温度测量。本申请实施例提供的温度测量方法主要是针对非侵入式温度测量方式提出的。非侵入式温度测量是指测量待测对象(例如人体)的表面温度的测量方式。在非侵入温度测量方式下，为了使得测量到的温度值尽量接近待测对象的真实温度值，选定一具有封闭状态的空间进行温度测量。在本申请实施例中，将用于温度测量的空间称为温度测量空间。
本申请发明人想到温度测量空间的封闭状态可能会被破坏。例如，在连续体温测量过程中，以腋下测量为例，受测者可能发生如举手、抬手臂、晃动肩膀等动作，从而导致腋下相对封闭的空间被破坏。温度测量空间的封闭状态一旦被破坏，温度传感器很容易受到环境温度的影响，导致测量到的温度值与受测者的实际温度值有一定误差，测量结果不够准确。
针对上述问题，本申请实施例提供一种解决方案，主要原理是：采用至少两个温度传感器，结合温度测量空间的状态的识别，在识别出温度测量空间从封闭状态转换为非封闭状态时，基于至少两个温度传感器在温度测量空 间处于非封闭状态时的测量值，获得待测对象的温度值，而不是直接将温度传感器的测量值作为待测对象的温度值，充分考虑了环境温度对温度传感器的影响，有利于降低测量到的待测对象的温度值与待测对象的实际温度值之间的误差，提高温度测量的准确性。
以下结合附图，详细说明本申请各实施例提供的技术方案。
本申请各实施例提供的温度测量方法可基于图1所示温度测量系统实现，但不限于此。如图1所示，该温度测量系统包括：控制设备10以及温度测量设备20。
温度测量设备20包括至少两个温度传感器，主要用于测量其所在位置或所处环境的温度。所述至少两个包括两个或两个以上。本实施例并不限定温度传感器的具体数量。
例如，在温度测量设备20的一种可选结构中，温度测量设备20包括两个温度传感器，两个温度传感器相对设置于温度测量设备20的主体上，以在温度测量时实现互补。
另外，值得说明的是，根据温度测量场景的不同，定温度测量设备20的实现结构以及外形都会有所不同。可选的，温度测量设备20可以是扁平近似椭圆的水滴形，这种外形可以降低使用时的异物感。
在本实施例中，将需要测量温度的对象称为待测对象。根据应用场景的不同，待测对象会有所不同，例如可以是人体、动物或某些密闭空间等。待测对象具有一定的温度测量空间，温度测量设备20位于温度测量空间内进行温度测量，这意味着，至少两个温度传感器位于温度测量空间内。
例如，待测对象为人体，则温度测量空间可是腋下、口腔、肛门等部位形成的相对较为封闭的空间；相应的，温度测量设备20可置于人体的腋下、口腔、肛门等部位，以便测量人体体温。例如，若温度测量设备20为扁平近似椭圆的水滴形，且包括相对设置的两个温度传感器，则可以通过医用胶布将温度测量设备20置于人体的腋下，其中一个温度传感器紧贴腋下皮肤。
控制设备10与温度测量设备20之间可以是无线或有线网络连接，主要 用于采集至少两个温度传感器的测量值，对采集到的测量值进行处理，以获得待测对象的温度值。在实现上，控制设备10可以是任何具有一定处理能力的设备，例如计算机、智能手机、笔记本、平板电脑、服务器等。
在本实施例中，若控制设备10通过移动网络与温度测量设备20通信连接，该移动网络的网络制式可以为2G(GSM)、2.5G(GPRS)、3G(WCDMA、TD-SCDMA、CDMA2000、UTMS)、4G(LTE)、4G+(LTE+)、WiMax等中的任意一种。控制设备10除了通过移动网络与温度测量设备20通信连接之外，还可以通过Wi-Fi、蓝牙、红外等无线方式与温度测量设备20通信连接。
其中，温度测量空间的封闭状态属于正常的温度测量状态。在温度测量空间处于封闭状态的情况下，至少两个温度传感器几乎不受环境温度的影响，至少两个温度传感器的测量值比较相近，也比较接近待测对象的温度值。在这种情况下，控制设备10可以连续采集至少两个温度传感器的测量值，并选择最大测量值作为待测对象的温度值。
在实际应用中，温度测量空间很可能会被破坏。针对该情况，结合图1所示温度测量系统，本申请实施例从控制设备10的角度，提供了一种温度测量方法。如图2所示，所述温度测量方法包括：
201、采集至少两个温度传感器的测量值，所述至少两个温度传感器位于待测对象的温度测量空间内。
202、根据所述至少两个温度传感器的测量值的变化趋势，确定所述温度测量空间从封闭状态转换为非封闭状态。
203、根据所述至少两个温度传感器在所述温度测量空间处于非封闭状态时的测量值，获得所述待测对象的温度值。
一般来说，待测对象的温度不同于环境温度，或者高于环境温度，或者低于环境温度。在温度测量空间的封闭状态被破坏的情况下，至少两个温度传感器的测量值都会趋向于环境温度，并且至少两个温度传感器的测量值趋向于环境温度的速度不同，暴露越多的温度传感器的测量值趋向于环境温度的速度越快。基于此，控制设备10可根据至少两个温度传感器的测量值的变 化趋势，判断温度测量空间的封闭状态是否被破坏。
在一可选实施方式中，待测对象的温度高于环境温度。例如，在测量人体体温的应用中，人体体温一般高于环境温度。在这种情况下，如果温度测量空间的封闭状态被破坏，温度传感器的测量值会逐渐下降以趋于环境温度。基于此，控制设备10可以判断至少两个传感器的测量值是否呈下降趋势，并且至少两个温度传感器的测量值之间的差值是否符合设定温差条件；当至少两个传感器的测量值呈下降趋势，且至少两个温度传感器的测量值之间的差值符合设定温差条件时，确定温度测量空间从封闭状态转换为非封闭状态。
根据应用场景的不同，上述温差条件会有所不同。例如，以温度测量设备20包括相对设置的两个温度传感器为例，则一种温差条件可以是要求两个温度传感器的测量值至少相差一定度数，例如0.4度。在该示例中，控制设备10可以判断两个传感器的测量值是否呈下降趋势，并且两个温度传感器的测量值是否至少相差0.4度；如果判断结果均为是，则确定温度测量空间从封闭状态转换为非封闭状态。
在一可选实施方式中，待测对象的温度低于环境温度。例如，在测量冰柜或冰箱的制冷效果的应用中，冰柜或冰箱里的温度一般低于环境温度。在这种情况下，如果温度测量空间的封闭状态被破坏，温度传感器的测量值会逐渐上升以趋于环境温度。基于此，控制设备10可以判断至少两个传感器的测量值是否呈上升趋势，并且至少两个温度传感器的测量值之间的差值是否符合设定温差条件；当至少两个传感器的测量值呈上升趋势，且至少两个温度传感器的测量值之间的差值符合设定温差条件时，确定温度测量空间从封闭状态转换为非封闭状态。
当确定温度测量空间的封闭状态被破坏，即从封闭状态转换为非封闭状态时，至少两个温度传感器的测量值会受环境温度的影响，与待测对象的实际温度值有一定误差。对此，控制设备10不再是直接选择最大测量值作为待测对象的温度值。考虑到很多时候，温度测量空间的封闭状态一般是暂时性被破坏，很快会重新恢复到封闭状态，此时温度传感器的测量值不会下降很 多。基于该考虑，控制设备10可以根据至少两个温度传感器在温度测量空间处于非封闭状态时的测量值，通过一定补偿算法获得待测对象的温度值。这充分考虑了环境温度对温度传感器的影响，有利于降低测量到的待测对象的温度值与待测对象的实际温度值之间的误差，提高温度测量的准确性。
在上述实施例或下述实施例中，在待测对象为人体等情况下，待测对象的温度一般会高于环境温度。在这种情况下，当温度测量空间从封闭状态转换为非封闭状态时，温度传感器的测量值会下降，按照传热学原理，温度传感器的测量值会按照下述公式(1)所示非线性衰减关系下降。
T＝(T0-C)e-Bt+C  (1)
其中，T表示温度传感器在温度测量空间处于非封闭状态时的测量值；T0是温度传感器在温度测量空间处于封闭状态时的测量值，即待测对象的温度值；B表示温度传递系数，所述温度传递系数是指至少两个温度传感器所在温度测量设备的系数，该系数可通过测量或实验获得，一般设备出厂时该系数就确定了；C为一常量；t表示时间。
但，本申请发明人经过研究发现，在较短时间内，温度传感器的测量值可认为是线性下降的，并发现可以用公式(2)所示线性衰减关系表示温度传感器的测量值的下降。基于此，可以用公式(2)代替公式(1)，以简化计算复杂度，提高获得待测对象的温度值的效率。
T＝kt+T0  (2)
在公式(2)中，T表示温度传感器在温度测量空间处于非封闭状态时的测量值；T0是温度传感器在温度测量空间处于封闭状态时的测量值，即待测对象的温度值；t表示时间。
基于上述分析，结合图1所示温度测量系统，本申请又一实施例提供了一种温度测量方法。所述方法主要从控制设备10的角度进行描述。如图3所示，所述温度测量方法包括：
301、采集至少两个温度传感器的测量值，所述至少两个温度传感器位于 待测对象的温度测量空间内。
302、根据所述至少两个温度传感器的测量值的变化趋势，确定所述温度测量空间从封闭状态转换为非封闭状态。
303、根据温度传递系数，确定线性补偿时间范围。
304、在线性补偿时间范围内，叠加至少两个温度传感器在所述温度测量空间处于非封闭状态时的测量值，作为待测对象的温度值。
关于步骤301-302，可参见前述方法实施例中的相应描述，在此不再赘述。
在本实施例中，在确定温度测量空间从封闭状态转换为非封闭状态的情况下，控制设备10可以根据温度传递系数，确定线性补偿时间范围；所述线性补偿时间范围是指在确定温度测量空间从封闭状态转换为非封闭状态后，可以采用线性方式进行温度补偿的时间段，该时间段一般是指确定温度测量空间从封闭状态转换为非封闭状态后的一小段时间。
在线性补偿时间范围内，控制设备10以线性方式，叠加至少两个温度传感器在温度测量空间处于非封闭状态时的测量值，作为待测对象的温度值。
在上述线性补偿方案中，线性补偿时间范围的确定是关键。本申请发明人在经过大量研究后发现，温度传递系数与线性补偿时间范围存在下述公式(3)所示的关系。基于此，可以根据下述公式(3)，计算线性补偿时间范围。
B*t<G  (3)
在公式(3)中，B表示温度传递系数；t表示线性补偿时间范围；G为基于温度误差允许范围确定的经验值。其中，根据应用场景的不同，温度误差允许范围会有所不同。例如，在体温测量应用中，温度误差允许范围为5％左右，当然根据精度要求的不同5％可以变化。
为便于推导G，设温度误差允许范围为δ，则为了可以使用线性补偿，将上述公式(1)中的e-Bt利用泰勒级数进行线性展开，得到e-Bt≈1+(-Bt)。其中，为了保证温度误差满足精度要求，对e-Bt的线性展开需要在满足温度误差允许范围的条件下成立，即(e-Bt-(1+(-Bt)))/e-Bt≤δ。假设δ＝5％，则可以根据公式(e-Bt-(1+(-Bt)))/e-Bt＝5％，计算出Bt＝0.287，即G＝0.287。
可选的，在线性补偿时间范围内，叠加至少两个温度传感器在温度测量空间处于非封闭状态时的测量值的步骤，可以为：基于上述公式(2)所示测量值的线性衰减关系，可以确定至少两个温度传感器各自对应的线性叠加系数；在线性衰减时间范围内，基于至少两个温度传感器各自对应的线性叠加系数，以线性方式，叠加至少两个温度传感器在温度测量空间处于非封闭状态时的测量值，作为待测对象的温度值。
在一应用示例中，温度测量设备20包括相对设置的两个温度传感器，记为第一温度传感器和第二温度传感器。在该示例中，结合公式(2)推导出两个温度传感器各自对应的线性叠加系数。具体推导过程如下：
设在温度测量空间从封闭状态转换为非封闭状态后的时间t内，第一温度传感器和第二温度传感器的测量值分别表示为：
T1＝k1t+T0                  (4)
T2＝k2t+T0                  (5)
基于上述公式(4)和公式(5)，分别计算时间t，公式如下：
t＝(T1-T0)/k1                 (6)
t＝(T2-T0)/k2                 (7)
进一步，基于公式(6)和(7)，可以获得下述公式(8)-(13)：
(T1-T0)/k1＝(T2-T0)/k2          (8)
T1k2-T0k2＝T2k1-T0k1          (9)
T0(k1-k2)＝T2k1-T1k2          (10)
T0＝T2k1/(k1-k2)+T1k2/(k2-k1)    (11)
K1＝k1/(k1-k2)                (12)
K2＝k2/(k2-k1)                 (13)
在上述推导过程中，T1表示第一温度传感器在温度测量空间处于非封闭状态时的测量值；k1表示第一温度传感器对应的衰减系数；K1表示第一温度传感器的线性叠加系数；T2表示第二温度传感器在温度测量空间处于非封闭状态时的测量值；k2表示第二温度传感器对应的衰减系数；K2表示第二温度 传感器的线性叠加系数；T0是温度传感器在温度测量空间处于封闭状态时的测量值，即待测对象的温度值；t表示时间。
进一步，基于线性叠加系数的线性叠加步骤，可以表示为如下公式(14)：
T0＝T2K1+T1K2  (14)
在根据上述公式(14)计算待测对象的温度值时，需要区分采集到的测量值是来自于第一温度传感器，还是来自于第二温度传感器。
在一种情况下，温度测量设备20上的温度传感器带有标记，便于区分第一温度传感器和第二温度传感器。在采用温度测量设备20通过腋下测量人体体温时，可以直接将第一温度传感器贴向腋下皮肤，第二温度传感器远离腋下皮肤。
在一种情况下，温度测量设备20上的温度传感器不带有标记，可以任意佩戴。在采用温度测量设备20通过腋下测量人体体温时，在腋下封闭空间形成过程中，贴向腋下皮肤的温度传感器的测量值较高，故可以将较高测量值对应的温度传感器作为第一温度传感器，将另一温度传感器作为第二温度传感器。
在本实施例中，在线性补偿时间范围内，采用线性方式进行温度补偿，不仅可以准确地获得待测对象的温度值，还可以简化计算复杂度，有利于提高获得待测对象的温度值的效率。
结合图3所示实施例，本申请又一实施例还提供一种温度测量方法。如图4所示，所述方法在步骤304之后，还包括：
305、在线性补偿时间范围之外，以非线性方式，叠加至少两个温度传感器在所述温度测量空间处于非封闭状态时的测量值，作为所述待测对象的温度值。
在本实施例中，在线性补偿时间范围内，以线性方式，叠加至少两个温度传感器在温度测量空间处于非封闭状态时的测量值，作为待测对象的温度值。在线性补偿时间范围之外，可以采用非线性方式，叠加至少两个温度传 感器在温度测量空间处于非封闭状态时的测量值，作为待测对象的温度值。例如，可以采用公式(1)叠加至少两个温度传感器在温度测量空间处于非封闭状态时的测量值。
在本实施例中，除了在线性补偿时间范围内，以线性方式进行温度补偿之外，还考虑到线性补偿时间范围之外，以非线性方式进行温度补偿，可以更加全面地获得待测对象的温度值。
结合图4所示实施例，本申请又一实施例提供一种温度测量方法。如图5所示，所述温度测量方法，在步骤305之后，还包括：
306、根据所述至少两个温度传感器的测量值的变化趋势，确定所述温度测量空间处于封闭状态。
307、从所述至少两个温度传感器在所述温度测量空间处于封闭状态时的测量值中，选择最大测量值作为所述待测对象的温度值。
温度测量空间的封闭状态被破坏后，有可能恢复。当恢复到封闭状态时，至少两个温度传感器几乎不受环境温度的影响，至少两个温度传感器的测量值会慢慢趋向于待测对象的真实温度，因此，控制设备10可以根据至少两个温度传感器的测量值的变化趋势，确定温度测量空间处于封闭状态，并从至少两个温度传感器在温度测量空间处于封闭状态时的测量值中，选择最大测量值作为待测对象的温度值。
在一种情况下，待测对象的温度高于环境温度。例如，在测量人体体温的应用中，人体体温一般高于环境温度。在这种情况下，如果温度测量空间从非封闭状态恢复到封闭状态，温度传感器的测量值会逐渐上升以趋于待测对象的实际温度值。基于此，控制设备10可以判断至少两个传感器的测量值是否呈上升趋势并在指定时间内或最终趋于一致；当至少两个传感器的测量值呈上升趋势并在指定时间内或最终趋于一致时，确定温度测量空间从非封闭状态转换为封闭状态。所述趋于一致是指至少两个传感器的测量值的差值小于指定度数，例如小于0.4度。
在另一种情况下，待测对象的温度低于环境温度。例如，在测量冰柜或冰箱的制冷效果的应用中，冰柜或冰箱里的温度一般低于环境温度。在这种情况下，如果温度测量空间从非封闭状态恢复到封闭状态，温度传感器的测量值会逐渐下降以趋于待测对象的实际温度值。基于此，控制设备10可以判断至少两个传感器的测量值是否呈下降趋势并在指定时间内或最终趋于一致；当至少两个传感器的测量值呈下降趋势并在指定时间内或最终趋于一致时，确定温度测量空间从非封闭状态转换为封闭状态。所述趋于一致是指至少两个传感器的测量值的差值小于指定度数，例如小于0.4度。
在本实施例中，充分考虑温度测量空间的封闭状态被破坏和恢复情况，有利于在各种情况下，准确地获得待测对象的温度值。
需要说明的是，上述实施例所提供方法的各步骤的执行主体均可以是同一设备，或者，该方法也由不同设备作为执行主体。比如，步骤201至步骤203的执行主体可以为设备A；又比如，步骤201和202的执行主体可以为设备A，步骤203的执行主体可以为设备B；等等。
