Description

附图说明
为了更清楚的说明本发明实施例中的方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图得到其他的附图。
图1为一种实施例的睡眠监测仪示意图；
图2为呼吸传感器的结构示意图；
图3为压电模块的结构示意图；
图4为脉搏传感器的结构示意图；
图5为一种睡眠监测仪带头的结构示意图；
图6为控制电路板中电子线路70的一种示意图。
具体实施方式
为使本发明的目的、方案和优点更加清楚，下面将结合附图对本发明的具体实施方式作进一步地详细描述。
请参看图1，一种睡眠监测仪1呈扁长条带形状，包括带头10和长条带20。呼吸传感器30和脉搏传感器40设置于长条带20内，呼吸传感器30和脉搏传感器40的个数在这里不限制。当呼吸传感器30与脉搏传感器40有多个时，呈阵列排列。长条带20由轻型薄片材料构成，长条带20的一端连接有带头10。
图2为呼吸传感器30的一种结构示意图。请参看图2，呼吸传感器30为双面拱型结构，包括拱型的上部分31和拱型的下部分32。
拱型的上部分31或者拱型的下部分32上有压电模块33，该压电模块33为长方形结构。压电模块33是由聚偏二氟乙烯(PVDF)高分子复合材料所做成的，灵敏度高。请参看图3，图3为压电模块33的结构示意图。该压电模块33包括PVDF材料331、绝缘膜332、电极333、聚酯膜334。PVDF材料331的四周被一层绝缘膜332围住，绝缘膜332的上下两面各粘贴有一层镀有电极333的聚酯膜334，该电极优选为康铜箔电极，该聚酯膜334保证电极333与PVDF材料331的镀层有良好的电接触。电极333用以保护和定性PVDF材料331的形状，避免短路。电极333还用于传输电信号，电极333用两根导线335 引出，通过导线335接入到控制电路当中。
呼吸传感器的拱型的上部分和拱型下部分分别向相反的方向拱起，拱型的上部分31和拱型下部分32结合成一种弹簧结构，在呼吸作用下，拱型的上部分31和拱型下部分32都会产生应力，通过压电模块33将传递的应力波动转换成电信号，由两跟导线335将电信号传递到控制电路当中。呼吸传感器30的双面拱形结构当受到应力时，拱型的上部分31和拱型下部分32都会受到应力，提高了传感器的灵敏度和信号的强度。
图4为脉搏传感器40的一种结构示意图。请参看图4，脉搏传感器40采用“薄壳”结构，该“薄壳”结构优选为双曲扁壳“薄壳”。脉搏传感器40包括压电模块43、收容槽41和位于压电模块43下的柱状空心结构42，柱状空心结构42置于收容槽41的内部，压电模块43置于收容槽41开口的一侧，具体地，收容槽为橡胶槽。压电模块43的结构请参看图3。当使用脉搏传感器40时，脉搏产生的应力会作用在压电模块43上，压电模块43将传递的应力波动转换成电信号传递到控制电路中。脉搏传感器40的“薄壳”结构由于中间是空的，因此应力会全部作用在压电模块43上，可以提高压电模块输出的电信号强度，使得压电模块43对微弱的脉搏信号反映灵敏。
图5为带头10的一种结构示意图。请参看图5，控制电路板11设置于带头10内，控制电路板11包括微处理器111、无线通讯模块112以及电子线路70。压电模块通过电极连接的两根导线335与控制电路板11相连。微处理器111与无线通讯模块112电连接。该睡眠监测仪通过无线通讯模块112与移动终端上绑定的相应应用程序相互通讯，该无线通讯模块112可以为蓝牙无线通讯模块。
请参看图6，为控制电路板11中电子线路70的一种示意图。电子线路70包括电荷放大电路71、第一滤波器72、电压放大电路73、第二滤波器74、电压提升电路75、A/D转换器76。与电极333连接的两根导线335在控制电路板11上连接着电荷放大电路71、第一滤波器72、电压放大电路73、第二滤波器74，电压提升电路75和一个A/D转换器76后与微处理器111相连。其中，电荷放大电路71用于使微弱电荷变换成与其成正比的电压；第一滤波器72用于过滤掉其他的信号(因为PVDF模块是很多的震动都可以检测到的)；电压放大模块73用于放大过滤后的电压；第二滤波器用于如果是检测脉搏的信号，过滤掉其他的信号，留下脉搏的信号；如果是检测呼吸的信号，过滤掉其他的信 号，留下呼吸的信号；电压提升电路75用于将第二滤波器出来的信号提升到正值以上，以方便A/D转换器76采集信号。具体地，第一滤波器72和第二滤波器74为低通滤波器，优选地，第一滤波器72和第二滤波器74为二阶巴特沃斯有源低通滤波器。
在本实施例中。呼吸传感器30对应有一电子线路，该电子线路中的第一滤波器和第二滤波器用来过滤其他的信号，留下呼吸的信号；脉搏传感器40对应有一电子线路，该电子线路中的第一滤波器和第二滤波器用来过滤其他的信号，留下脉搏的信号。
当压电模块33和/或压电模块43收到应力时，会向四周释放电子产生电信号，在没有电场的情况下，压电模块的压电方程为：
D＝d·σ
其中：D为应力大小及方向，d为压电应力常数矩阵，σ为单位PVDF材料面积方向上的电荷大小。电荷放大电路中有一个电容，假设电容的值为C，电荷放大电路中电容两端的电压，假设为U，则电压与电荷之间的关系式为
Q＝U/C
而
σ＝Q/(A·K)
其中，A为PVDF材料的面积大小，K为PVDF材料的灵敏度常系数，从而得到应力与电压之间的关系式为
D＝d·U/(A·K·C)
PVDF材料受到的应力大小与电压值成正比。
在本实施例中，通过监测电容两端的电压，并且利用压力与电压之间的关系式推算出PVDF材料所受到的压力的大小，并且通过所受的压力的变化来判断用户呼吸频率和脉搏频率。经过滤波后，由于呼吸的振动在一个周期内为连续振动，所以仅由呼吸振动产生的电压曲线为类似于正弦曲线的信号，而脉搏的振动电压信号为尖端脉冲信号，在监测呼吸频率的压电模块及电子线路中过滤掉其他的信号，得到呼吸周期中的信号；同理，在监测脉搏频率的压电模块及电子线路中过滤掉其他的信号，得到每两个尖端脉冲之间的区间即是一个脉搏振动的周期。
当用户压在长条带20上时，微处理器111接收到呼吸传感器或脉搏传感器的信号后，可对信号进行进一步的滤波。例如，微处理器111采用平均值滤波 法。具体地，微处理111将连续得到的n个数值作为一个数列，假设n＝256；每当微处理器111得到一个新的数值时，就把该数列的最后一个值去掉，把新的数值放在数列的首位，使得n始终保持256个；数列256个值中，去掉一个最大值和一个最小值，对剩下的254个值求平均值；将得到的平均值作为输出值。微处理器111的滤波对周期性干扰有良好的抑制作用，能过滤用户身体抖动产生的干扰。
微处理器111还会根据压电模块产生的电压来判定用户是否有翻身的行为。当用户翻身时，用户原本与压电模块接触的部位会离开监测仪，片刻之后，再重新接触，在离开压电模块后，压电模块检测不到振动，而当用户重新接触压电模块的瞬间，压电模块会产生巨大的电压，根据压电模块是否在监测不到振动后又监测到剧烈振动来判定用户是否翻了身。
本发明实施例中的睡眠监测仪通过移动终端应用程序唤起后进行工作，该睡眠监测仪把监测到的呼吸频率和心跳频率通过无线通讯模块112发送至移动终端，移动终端通过接收到的数据来判断睡眠时间，以及浅睡和深睡的时间，并且根据深睡和浅睡的时间来判定睡眠质量的优劣，然后把判定的睡眠时间和睡眠质量的结果在移动终端应用程序界面上显示出来，达到监测睡眠质量的目的。
该睡眠监测仪1中有电池，用以该睡眠监测仪的供电，该电池连接着一个USB接口，可以对电池进行充电。
上述睡眠监测仪只需用户压在上面即可使用，材料轻薄、使用舒适度高，携带方便；采用新型PVDF材料监测脉搏和呼吸频率，仪器灵敏，准确度高。该睡眠监测仪具有使用方便、易于推广的优点。
以上实施例仅为说明本发明的技术方案，而非对其限制，本领域的普通技术人员应当理解，依然可对前述记载的各个实施例进行修改或者采用部分技术特征等同替换，而这些修改和替换并不脱离本发明的技术原理也视为本发明的保护范围。
