Description

一种用于生理组织的探测器和探测方法 技术领域
本发明涉及探测器领域，具体而言，涉及一种用于生理组织的探测器和探测方法。
背景技术
传统的生物传感器有压力传感器、超声传感器、电磁传感器等等。压力传感器如传统的袖带式血压计，需要在人体组织上施加一定的压力，才能测到血压等生理特征，但是这样的测试往往令人不舒服。超声传感器需要专门的仪器和专业操作人员以及专业解读人员，不是普通大众所能家里配备的。
近几年流行的电磁传感器，是利用电磁场或者电磁波的变化，来探测人体的生理组织的状况。这种传感器无侵入、小巧、携带方便、操作简易，是将来人体组织探测的发展方向。现有技术中，接收天线接收到携带生理信号的无线探测电磁信号之后，通过一个匹配器进行阻抗匹配，以使接收电路解调出生理信号。但是，由于人体的差异性，以及天气、温度、湿度、衣物、年龄等等的差异性，都对测量人体生理组织的生物传感器提出了不同的天线和电路要求。所以，现有技术的探测器只能适应一部分人群，例如对20岁至50岁的人群比较适用，而其他年龄的人群由于生理情况差异较大，测试时误差较大，影响准确度。
但是这种传感器容易受到人体差异性的影响，从而影响探测结果。例如，男人女人、冬天夏天、雨天晴天、手腕粗细等等，都能造成测试的差异性很大，对天线和电路的要求的差异性也很大。
针对上述的问题，目前尚未提出有效的解决方案。

具体实施方式
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，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，都应当属于本发明保护的范围。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本发明的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含。
根据本发明实施例，提供了一种用于生理组织的探测器的实施例，图1是根据本发明第一实施例的用于生理组织的探测器的示意图，如图1所示，该探测器包括如下组成部分：
第一接收天线，用于接收探测电波，其中，探测电波中携带有生理信号，探测电波可以是一种频率的，也可以是多种频率的。
第一切换开关，与第一接收天线连接，用于切换电路连接，第一切换开关可以控制切换与第一匹配器或第二匹配器的连接，第一切换开关只能连接第一接收天线或第二接收天线中的一个。
第一匹配器，其中，在第一切换开关将第一匹配器接入电路时，第一匹配器对探测电波进行阻抗匹配，得到第一匹配信号。
第一接收电路，与第一匹配器连接，用于从第一匹配信号中解调出第一生理信号。由于第一匹配信号中携带有第一生理信号，因此，可以从第一匹配信号中解调出第一生理信号。
第二匹配器，其中，在第一切换开关将第二匹配器接入电路时，第二匹配器对探测电波进行阻抗匹配，得到第二匹配信号，第二匹配器和第一匹配器的阻抗不同，第一匹配器和第二匹配器的匹配状态不一样，可以是第一匹配器和第二匹配器的阻抗不用，也可以是其他匹配参数不同，由于第一匹配器和第二匹配器的匹配状态不一样，第一匹配器和第二匹配器的能够匹配出的生理信号的特征也可能不同，这样可以适应不同的人群的生理差异。
第二接收电路，与第二匹配器连接，用于从第二匹配信号中解调出第二生理信号。
处理器，用于控制第一切换开关将高质量信号所对应的匹配器接入电路，其中，高质量信号为第一生理信号和第二生理信号中质量参数较高的信号。由于不同人群的生理差异，例如，男性、女性、老年、青年、儿童等群体的生理差异，不同人体的生理信号的强度不同，同样的生理信号在不同的匹配器匹配后的匹配信号不同，从匹配信号中解调出的生理信号也不用，因此，两个匹配器中的生理信号质量参数不同，选取其中质量参数较高的一个信号来计算待测生理组织的生理参数，能够提高生理参数检测结果的准确性。处理器还用于根据高质量信号计算待测生理组织的生理参数。
通过上述实施例，采用不同参数的匹配器对携带生理信号的探测电波进行匹配，能够适应不同人群生理差异性得到更加精确的生理组织检测结果，解决了现有技术中通过电磁方法测量人体生理参数时，因人群差异导致的测试结果不准确、普适性差的技术问题，达到了提高生理参数检测结果准确性和人群普适性的技术效果。
在本发明实施例中，第一接收天线接收第一频率的探测电波，第一匹配器对第一频率的探测电波进行阻抗匹配，得到第一匹配信号，第二匹配器对第一频率的探测电波进行阻抗匹配，得到第二匹配信号。
在本发明实施例中，M组天线接收探测电波，其中，探测电波中携带有生理信号；多路切换开关实现M组接收天线与N路匹配器的连接；N路匹配器分别对接收信号进行匹配，得到N路匹配信号；N路匹配信号连接L路接收电路；L路接收电路解调出L路生理信号；处理器控制多路切换开关实现电路连接的切换，从L路生理信号中，选择信号质量较好的一路或多路用于生理信息处理。M，N和L都是正整数，其数值可以是多种数值的组合。
在本发明实施例中，将所述匹配切换方法可以类推到更多种组合，通过多组天线 实现多个频率、多个位置探测电波的接收，通过不同参数的匹配器对携带生理信号的探测电波进行匹配，可以获得多路优质信号，能够适应不同人群生理差异性得到更加精确的生理组织检测结果，进而解决了现有技术中通过电磁方法测量人体生理参数，因人群差异带来的测试结果不准确、普适性差的技术问题。
图2是根据本发明第二实施例的用于生理组织的探测器的示意图，如图2所示，接收天线一310接收到检测到的携带生理信号的频率为f1的无线探测电磁信号，由切换开关340进行两路切换。当开关340切换到第一路时，第一匹配器120进行阻抗匹配，阻抗匹配使得接收到的信号幅度增大、信噪比也增强，以使接收电路130解调出生理信号。当开关340切换到第二路时，第二匹配器220进行阻抗匹配，使得第二路接收到的信号幅度增大、信噪比也增强，以使接收电路230解调出生理信号。处理器(可以是主处理器CPU)比较两路接收到的信号质量，然后控制切换开关340始终处于较好质量的那一路上。在此，第一匹配器120和第二匹配器220的匹配状态不一样，以适应更多的人群。处理器还用于根据高质量信号计算待测生理组织的生理参数。
作为一种可选的实施方式，第一接收天线用于接收第一频率和第二频率的探测电波，第一匹配器用于对第一频率的探测电波进行阻抗匹配，得到第一匹配信号，第二匹配器用于对第二频率的探测电波进行阻抗匹配，得到第二匹配信号。
图3是根据本发明第三实施例的用于生理组织的探测器的示意图，如图3所示，接收天线一310接收到检测到的携带生理信号的频率为f1的无线探测电磁信号，同时，接收天线一310也接收到检测到的携带生理信号的频率为f2的无线探测电磁信号。由切换开关340进行两路切换。当切换开关340切换到第一路时，第一匹配器120进行阻抗匹配到f1的探测信号，使得接收到的信号幅度增大、信噪比也增强，以使接收电路130解调出生理信号。当开关340切换到第二路时，第二匹配器220进行阻抗匹配到f2的探测信号，使得第二路接收到的信号幅度增大、信噪比也增强，以使接收电路230解调出生理信号。主处理器CPU比较两路接收到的信号质量，然后控制开关始终处于较好质量的那一路上。在此，第一匹配器120和第二匹配器220的匹配状态不一样，以适应更多的人群。处理器还用于根据高质量信号计算待测生理组织的生理参数。

通过本发明实施例的上述步骤，采用不同参数的匹配器对携带生理信号的探测电波进行匹配，能够适应不同人群生理差异性得到更加精确的生理组织检测结果，实现了提高生理参数检测结果准确性的技术效果，进而解决了现有技术中通过电磁方法测量人体生理参数时，因人群差异导致的测试结果不准确、普适性差的技术问题。
