Description

一种足部状态预警方法及装置 技术领域
本发明属于可穿戴电子设备技术领域，尤其涉及一种足部状态预警方法及装置。
背景技术
糖尿病溃疡是糖尿病的一种并发症，多发于患者脚部，因此又称为糖尿病足，其为导致糖尿病患者致残死亡的主要原因之一。研究表明，在用户已确诊糖尿病的情况下，若用户的足部皮肤温度出现异常，则该用户将有较大的概率会引起糖尿病足。而在确诊糖尿病足时，用户通常已经出现了足底溃疡以及肢端坏疽等症状，甚至可能到了需要截肢的地步。因此，加强对足部皮肤温度的监测，能够有助于提醒用户及时就诊，降低其患有糖尿病足的风险，达到了预警的效果。
为了监测用户的足部皮肤温度，目前市面上出现了可用于测量温度的保健袜子。用户只要穿上该袜子，便能迅速地完成足底温度的测量。然而，在用户的日常活动过程中，由于袜子不可能无时无刻都紧贴着用户的足部皮肤，故采集得到的实时温度值可能会与用户的实际足部皮肤温度有较大的差距，由此降低了足温测量的准确率。基于错误的足温数据来发出预警提示信息，将会导致误报率较高的情况出现。
发明内容
有鉴于此，本发明实施例提供了一种足部状态预警方法及装置，以解决现有技术中，足温测量准确率低以及预警提示信息误报率较高的问题。
本发明实施例的第一方面提供了一种足部状态预警方法，包括：
控制第一温度传感器采集袜子所处环境的环境温度值，并同步控制位于所述袜子的袜体的多个第二温度传感器分别采集预设的人体足部位置的足部温度值；
若任一所述第二温度传感器所采集到的所述足部温度值与同一时刻采集到的所述环境温度值相同，且该第二温度传感器与其位置相邻的所述第二温度传感器所采集到的所述足部温度值之间的差值大于第一预设阈值，则控制该第二温度传感器以第二采集频率进行温度采集；
若任一所述第二温度传感器所采集到的所述足部温度值与同一时刻采集到的所述环境温度值不同，则控制该第二温度传感器以第一采集频率进行温度采集；
对采集到的所述足部温度值进行分析处理，并基于分析结果，发出足部状态预警信息；
其中，所述第一采集频率小于所述第二采集频率。
本发明实施例的第二方面提供了一种足部状态预警装置，包括：
第一采集单元，用于控制第一温度传感器采集袜子所处环境的环境温度值，并同步控制位于所述袜子的袜体的多个第二温度传感器分别采集预设的人体足部位置的足部温度值；
第一控制单元，用于若任一所述第二温度传感器所采集到的所述足部温度值与同一时刻采集到的所述环境温度值相同，且该第二温度传感器与其位置相邻的所述第二温度传感器所采集到的所述足部温度值之间的差值大于第一预设阈值，则控制该第二温度传感器以第二采集频率进行温度采集；
第二控制单元，用于若任一所述第二温度传感器所采集到的所述足部温度值与同一时刻采集到的所述环境温度值不同，则控制该第二温度传感器以第一采集频率进行温度采集；
第一预警单元，用于对采集到的所述足部温度值进行分析处理，并基于分析结果，发出足部状态预警信息；
其中，所述第一采集频率小于所述第二采集频率。
本发明实施例的第三方面提供了一种足部状态预警装置，包括存储器、处理器以及存储在所述存储器中并可在所述处理器上运行的计算机程序，所述处理器执行所述计算机程序时实现如上述第一方面所述足部状态预警方法的步骤。
本发明实施例的第四方面提供了一种计算机可读存储介质，所述计算机可读存储介质存储有计算机程序，所述计算机程序被处理器执行时实现如上述第一方面所述足部状态预警方法的步骤。
本发明实施例中，通过同步采集环境温度值以及人体足部位置的足部温度值，在足部温度值与同步测量得到的环境温度值相同的情况下，能够确定当前时刻所测量得到的足部温度值可能不是人体足部位置的足部温度值，可能是温度传感器并未紧贴用户足部皮肤时采集到的环境温度值；通过计算足部温度值与其位置相邻的温度传感器所采集到的足部温度值的差值，在该差值大于预设阈值的情况下，能够确定出该足部温度值确实为环境温度值而非足温值，从而准确地识别出了异常数据。在异常数据出现的情况下，通过增大温度传感器的采集频率，保证了在尽量短的时间内可以重新采集到正确的足部温度值。在异常数据未出现的情况下，由于足部温度在短暂时间内相对稳定，因而以较低的采集频率采集足部温度值，能够降低袜子的能耗。本发明实施例在提高足温测量准确率的同时，基于准确率较高的足温数据来发出预警提示信息，由此也进一步地降低了预警提示信息的误报率。

具体实施方式
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、技术之类的具体细节，以便透彻理解本发明实施例。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施例中也可以实现本发明。在其它情况中，省略对众所周知的系统、装置、电路以及方法的详细说明，以免不必要的细节妨碍本发明的描述。
为了说明本发明所述的技术方案，下面通过具体实施例来进行说明。
首先，对本发明实施例中提及的袜子进行解释说明。本发明实施例中所涉及的袜子，其由柔性面料制成，且在柔性面料非贴近人体皮肤的一侧镶嵌有多个温度传感器。每个温度传感器固定于袜子的不同位置点，以使得用户穿上该袜子之后，各个温度传感器能够透过该柔性面料，间接贴附于用户足部的各个位置点。
在具体实现中，示例性地，对于每一只袜子来说，在其外表面设置有电线以及控制模块。控制模块内部包含有电路板以及电池，所述电池用于为所述电路板以及为与所述电路板电性相连的各个温度传感器供电。所述控制模块固定于袜子的袜口处，且位于非贴近人体皮肤的一侧。作为另一种具体的实现方式，控制模块及其焊接处都包裹有防水胶，电线外侧也包裹有防水胶，使得该袜子能够被洗涤。
在本发明的各个实施例中，控制模块可通过有线、无线或者蓝牙等连接方 式，与远程的终端设备通信。所述终端设备为具有显示屏的智能终端，例如手机、平板、笔记本电脑以及计算机等。该终端设备内部运行有应用程序客户端，基于该应用程序客户端，可以实现与控制模块之间的数据交换。例如，控制模块可将采集到的足温数据通过无线网络传输至远程的终端设备中，以供用户实时查看自身的足温数据。并且，控制模块也可根据终端设备所下发的指令，根据该指令来控制温度传感器执行运作等。
为了说明本发明所述的技术方案，下面通过具体实施例来进行说明。
图1示出了本发明实施例提供的足部状态预警方法的实现流程，详述如下：
S101：控制第一温度传感器采集袜子所处环境的环境温度值，并同步控制位于所述袜子的袜体的多个第二温度传感器分别采集预设的人体足部位置的足部温度值。
温度传感器是指能感受温度并转换成可用输出信号的传感器。示例性地，温度传感器可以由热敏电阻来实现，其电阻阻值会随温度增加而降低。因此，根据预设的电阻阻值与温度值的对应关系，可将实时测量得到的电阻阻值转换为温度数据。
在本发明实施例中，第一温度传感器集成于电路板。由于电路板位于控制模块内部，因而在第一温度传感器执行运作时，其不会与人体皮肤接触，故第一温度传感器所采集得到的温度值为袜子所处环境的环境温度值。示例性地，包含该第一温度传感器的控制模块缝制于袜口的外侧，且控制模块具有防水外壳。对于位于袜子的袜体的多个第二温度传感器而言，当用户在使用该袜子时，足部将放置于袜体之内，故第二温度传感器将透过袜体的柔性面料，贴附于对应的人体足部位置，由此将第二温度传感器所采集得到的温度值确定为人体足部位置的足部温度值。
在第一温度传感器工作的同时，第二温度传感器也同步执行工作。在本发明实施例中，基于相同时刻而采集到的各个温度值之间存在对应关系。
S102：若任一所述第二温度传感器所采集到的所述足部温度值与同一时刻 采集到的所述环境温度值相同，且该第二温度传感器与其位置相邻的所述第二温度传感器所采集到的所述足部温度值之间的差值大于第一预设阈值，则控制该第二温度传感器以第二采集频率进行温度采集。
通常情况下，人体足部位置的皮肤温度与环境温度值之间会存在偏差。在任一时刻，若第二温度传感器采集得到的足部温度值与其对应的环境温度值相同，则表示该足部温度值存在采集异常的可能性，可能的原因是该第二温度传感器并未紧贴用户的足部皮肤。但是，由于足部温度值也可能出现与环境温度值相同的情况，因此，为了进一步确认该足部温度值的正确性，确定出与该第二温度传感器处于相邻位置的另一第二温度传感器，并读取确定出的该第二温度传感器在同一时刻所采集得到的足部温度值。
一般而言，相邻的足部皮肤的温度不会相差太大，因而若两个第二温度传感器所采集得到的足部温度值的差值大于预设阈值，则表示存在异常可能性的足部温度值的确为环境温度值而不是人体足部位置的温度值。故对该足部温度值进行删除处理，并增大该第二温度传感器的采集频率，以重新采集人体足部位置的温度值。由此可以在该第二温度传感器重新贴附人体足部位置的时刻，以最快的速度重新获取该位置的足部温度值。
在本发明实施例中，第二温度传感器默认以第一采集频率进行工作，且为了方便描述和区分，将增大后的第二温度传感器的采集频率称为第二采集频率。
若采集到的足部温度值与同一时刻采集到的环境温度值相同，且与位置相邻的第二温度传感器所采集到的足部温度值之间的差值小于第一预设阈值，则保持第二温度传感器的采集频率为第一采集频率。
S103：若任一所述第二温度传感器所采集到的所述足部温度值与同一时刻采集到的所述环境温度值不同，则控制该第二温度传感器以第一采集频率进行温度采集。
若第二温度传感器所采集到的足部温度值一直与同一时刻采集到的环境温度值不同，则令第二温度传感器保持以第一采集频率进行足温数据的采集。若 根据上述S102的实现原理，判断得出第二温度传感器所采集到的足部温度值存在异常，并增大了该第二温度传感器的采集频率，则在重新检测到其采集到的足部温度值与同一时刻采集到的环境温度值不同时，再次令该第二温度传感器以第一采集频率进行足温数据的采集。
S104：对采集到的所述足部温度值进行分析处理，并基于分析结果，发出足部状态预警信息；其中，所述第一采集频率小于所述第二采集频率。
在预设时长内，对第二温度传感器所采集得到的各个足部温度值进行分析，确定出以第一采集频率采集得到的各个足部温度值。由于第二温度传感器以第一采集频率所采集到的足部温度值均为人体足部位置的正常温度值，而不是在非紧贴人体足部时所采集到的温度值，因而本发明实施例中，基于筛选出的足部温度值来判断是否需要发出足部状态预警信息。
本发明实施例中，通过同步采集环境温度值以及人体足部位置的足部温度值，在足部温度值与同步测量得到的环境温度值相同的情况下，能够确定当前时刻所测量得到的足部温度值可能不是人体足部位置的足部温度值，可能是温度传感器并未紧贴用户足部皮肤时采集到的环境温度值；通过计算足部温度值与其位置相邻的温度传感器所采集到的足部温度值的差值，在该差值大于预设阈值的情况下，能够确定出该足部温度值确实为环境温度值而非足温值，从而准确地识别出了异常数据。在异常数据出现的情况下，通过增大温度传感器的采集频率，保证了在尽量短的时间内可以重新采集到正确的足部温度值。在异常数据未出现的情况下，由于足部温度在短暂时间内相对稳定，因而以较低的采集频率采集足部温度值，能够降低袜子的能耗。本发明实施例在提高足温测量准确率的同时，基于准确率较高的足温数据来发出预警提示信息，由此也进一步地降低了预警提示信息的误报率。
作为本发明的一个实施例，如图2所示，上述S101具体包括：
S1011：在待机模式下，控制所述多个第二温度传感器以第三采集频率分别进行温度采集。
在用户并未使用袜子之前，位于袜体上的各个第二温度传感器工作于待机模式，并以待机模式所对应的第三采集频率分别采集预设的各个位置点的足部温度值。值得注意的是，此时第二温度传感器采集到温度值并非人体真正的足部温度值，仅用于区别于第一温度传感器所采集得到的环境温度值。其中，第三采集频率低于上述第一采集频率。此时，第一温度传感器也工作于待机模式，并以待机模块所对应的第三采集频率来采集袜子所处环境的环境温度值。
S1012：若多个所述第二温度传感器所采集到的所述足部温度值同步发生变化，且所述环境温度值保持不变，则控制所述多个第二温度传感器以第一采集频率分别进行温度采集；其中，所述第三采集频率小于所述第一采集频率。
在预设时长内，每一第二温度传感器均可连续采集得到多个足部温度值，第一温度传感器也可连续采集得到多个环境温度值。若在任一时刻，位于袜子的袜体上的多个第二温度传感器所对应采集到的足部温度值均同时出现了升温或者降温的情况，而该时刻对应采集到的环境温度值依然与上一时刻所采集到的环境温度值相同，则确定当前时刻用户正在使用袜子，用户的足部进入了袜体之内。此时，令第一温度传感器以及第二温度传感器工作于正常模式，并控制第一温度传感器以及第二温度传感器以正常模式对应的第一采集频率分别采集各个位置点的温度值。
其中，上述足部温度值同时出现变化的第二温度传感器的数量至少为两个以上。
本发明实施例中，基于人体足部温度与环境温度值不同的原理，通过确定出多个足部温度值同时出现变化的时刻，并判断该时刻下环境温度值是否同时出现改变，能够在环境温度值未发生改变而足部温度值发生改变的情况下，自动控制位于袜子的袜体的各个温度传感器以正常模式对应的采集频率采集用户足部的温度值，保证了用户不再需要手动启动足温检测功能后才能执行足温的测量，提高了足温数据采集的智能化程度。
作为本发明的另一实施例，如图3所示，上述足部状态预警方法还包括：
S105：分别控制位于所述袜子的袜体的各个压力传感器采集预设的人体足部位置的压力值。
本发明实施例中，在袜子的袜底上除了设置温度传感器外，还设置有多个压力传感器。压力传感器包括弹性体以及粘贴于弹性体表面的电阻应变片。由于袜子由弹性面料制作而成，因而当用户穿上袜子时，足部皮肤将对袜子产生压力，使得压力传感器中的弹性体以及粘贴于其表面的电阻应变片也随之产生形变，电阻应变片的电阻阻值也发生改变。因此，通过对该电阻应变片的电阻阻值进行测量，根据预设的电阻阻值与压力值的对应关系，能够确定出各个时刻的所检测到的压力值。
S106：根据各个所述人体足部位置的压力值，生成用户的第一足部压力分布模型。
当各个压力传感器位于袜子的袜底时，基于测量得到的各个足底位置的压力值，可生成足部压力分布平面图。上述足部压力分布平面图属于第一足部压力分布模型。
示例性地，对第一足部压力分布模型的生成过程进行描述：在终端界面中渲染人体足部区域示意图，所述人体足部区域示意图包括多个足底位置区域；根据压力传感器在袜子中所固定的位置点，将各个压力传感器所测量得到的压力值标记于人体足部区域示意图中的相应足底位置区域，并以压力值所对应的压力等级色彩元素来渲染各个足底位置区域。
S107：获取与用户的个人属性数据匹配的第二足部压力分布模型。
本发明实施例中，在终端设备所运行的应用程序客户端中，请求用户输入其个人属性数据，包括但不限于身高、年龄、体重、脂肪率以及血糖率等。终端设备将用户的个人属性数据上传至远程服务器，以使远程服务器通过大数据处理技术，对该个人属性数据进行分析处理，并返回与该个人属性数据匹配的第二足部压力分布模型。
其中，远程服务器返回的第二足部压力分布模型与用户的第一足部压力分 布模型的生成方式相同。
S108：获取第三足部压力分布模型，所述第三足部压力分布模型基于所述用户的历史压力值所生成。
获取预设的与用户相关的历史足部压力分布模型，该历史足部压力分布模型即为上述第三足部压力分布模型，其根据用户在非运动状态下所采集得到的历史压力值生成。其中，各个历史压力值所分别对应的各个足底位置区域均与当前时刻所采集到的各个压力值所分别对应的各个足底位置区域相同。
S109：计算所述第一足部压力分布模型与所述第二足部压力分布模型的第一相似度以及计算所述第一足部压力分布模型与所述第三足部压力分布模型的第二相似度。
本发明实施例中，第一相似度以及第二相似度的计算方式可以利用现有的图像相似度算法来实现，也可以利用其他算法来实现，在此不作限定。
例如，在上述示例中，第一足部压力分布模型中包含有以多种色彩元素标记的足底位置区域，而第二足部压力分布模型也包含有以多种色彩元素标记的足底位置区域，则根据每一足部位置区域在两个模型中所分别对应的色彩元素的色彩吻合度，可将该色彩吻合度确定为该足底位置区域的相似度。计算出各个足底位置区域的相似度后，根据各个足底位置区域所对应的预设权重，可计算出第一足部压力分布模型与第二足部压力分布模型的相似度。
S110：对所述第一相似度以及第二相似度进行加权处理，得到模型相似度。
第一相似度以及第二相似度分别具有对应的一个权重比值。若通过上述S109所得到的第一相似度为a，其对应预设的权重比值为A，第二相似度为b，其对应预设的权重比值为b，则计算得到的模型相似度为A*a+B*b。
S111：若所述模型相似度小于第二预设阈值，则发出足部状态预警信息。
若模型相似度小于第二预设阈值，则表示当前使用袜子的用户的足部压力分布与正常状态下的足部压力分布存在较大的差异，故当前用户很有可能会产生足部局部压迫的问题，由此容易导致血流不畅，从而增大了患有糖尿病足的 风险，因此，发出足部状态预警信息。
本发明实施例中，在袜体上设置压力传感器，结合足温数据以及足部压力数据来发出足部状态预警信息，加强了对用户足部状态的监测；通过计算用户当前时刻的足部压力分布模型与基于大数据所得到的不具有糖尿病足风险的用户的足部压力分布模型的第一相似度以及计算用户当前时刻的足部压力分布模型与历史足部压力模型的第二相似度，并获取加权后的模型相似度，能够综合用户自身的历史足部压力分布以及同类型用户的足部压力分布来发出足部状态预警信息，使得糖尿病足风险的判断准确度更高，因而提高了预警的有效性。
作为本发明的一个实施例，对足部状态预警信息的生成过程作进一步的限定。如图4所述，上述S104具体包括：
S1041：在预设时长内，获取与同一人体足部位置对应的各个所述足部温度值。
第二温度传感器位于袜体上的一个固定位置点，因而其对应的人体足部位置也固定。对于每一第二温度传感器来说，其在预设时长内采集得到的各个足部温度值即为对应同一人体足部位置的各个足部温度值。
S1042：若对应于同一所述人体足部位置的各个所述足部温度值均不属于预设的足温区间范围之内，则发出基于该人体足部位置的足部状态预警信息。
由上述分析可知，以第一采集频率采集得到的各个足部温度值均为人体足部位置的实际温度值。本发明实施例中，对在预设时长内以第一采集频率采集得到的各个足部温度值进行判断处理，确定该预设时长内的各个足部温度值是否持续超出预设的足温区间范围。其中，预设的足温区间范围为采集这些足部温度值的第二温度传感器所对应的人体足部位置的正常温度范围。例如，足背的足温区间范围为26℃至32℃。
若预设时长内的各个足部温度值都超过了预设的足温区间范围，则表示用户的足温异常状况已经不是瞬间发生的事情，已经持续了一小段时间，因而糖尿病足的患病风险相对较高，因此，发出这些足部温度值所对应的人体足部位 置的足部状态预警信息，提醒用户及时就诊，并提醒用户该人体足部位置可能是问题所在的区域。
本发明实施例中，仅在预设时长内所采集到的各个足部温度值均不属于预设的足温区间范围的情况下，才发出足部状态预警信息，提高了预警的准确率，不会因出现瞬间突发的温度异常现象就发出预警提示信息，减少了不必要的预警信息产生，降低了误报率。
作为本发明的又一实施例，如图5所示，上述S104还包括：
S1043：在显示界面中渲染包含足部各血管的足部透视模型。
本发明实施例中，显示界面包括终端设备的终端界面，也包括镶嵌于袜子外表面的显示屏。足部透视模型表示足部立体模型图，且该足部立体模型图中展示有各足部血管，包括人体脚掌内部的血管以及小腿上的血管。
当发出足部状态预警信息时，在显示界面中，同步渲染该足部透视模型。
S1044：基于发出了所述足部状态预警信息的人体足部位置，确定所述足部透视模型中与该人体足部位置关联的所述血管。
S1045：以预设的色彩元素标记确定出的所述血管，并将包含所述色彩元素的所述足部透视模型进行存储。
人体的各个足部位置区域均有对应的足部血管来完成供血，每个足部位置所对应的供血血管即为与该人体足部位置关联的血管。通过S1042确定出具有潜在风险的人体足部位置后，根据预存储的人体足部位置与血管的对应关系表，能够匹配出与该人体足部位置关联的血管。此时，在足部透视模型中，确定出表示这些血管的模型位置，并与预设的一种色彩元素将这些模型位置一一标记出来。
在实时展示了具有色彩元素标记的足部透视模型时，将该足部透视模型进行存储。例如，在终端界面中执行截图处理，并存储包含该足部透视模型的截图。
本发明实施例中，通过发出基于人体足部位置的预警信息，并在足部透视 模型中标记出与该人体足部位置关联的血管，使得用户根据当前所实时标记的足部血管，能够了解自己足部的哪些血管可能出现血流不畅，可能是导致足温异常的根源，便于用户加强对这些血管的保健以及护理。通过将包含色彩元素的足部透视模型进行存储，使得用户在就诊时，能够调用预存储的足部透视模型供医护人员参考，提高了诊断效率。
应理解，上述实施例中各步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
