具体实施方式
以下将以附图配合文字叙述公开本发明的多个实施方式,为明确说明起见,许多实务上的细节将在以下叙述中一并说明。然而,应了解到,这些实务上的细节不应用以限制本发明。此外,为简化图式起见,一些已知的结构与元件在图式中将以简单示意的方式绘出。
本发明为一种感测器的自动校正方法,较佳适用于人体移动感测器,例如焦电型红外线感测器(Pyroelectric Infrared Radiation Detector,PIR),但不以此为限。在其他实施例中,也可应用于其他类似的感测器,只要是利用物体移动侦测进一步控制设备的用途,皆可导入本发明中。
请参阅图1A及图1B,为一种感测器1,本实施例以焦电型红外线感测器(Pyroelectric Infrared Radiation Detector,PIR)为例,但不限于此。感测器1具有底部11、连接端部12、进线口13、感测单元14、中盖15、透镜16、遮片17及外盖18。连接端部12及进线口13设置于底部11上,可提供与其他被控设备(例如照明设备、门禁开关、监控设备及电器自动控制系统等)电连接。感测单元14为焦电型红外线感测器,与连接端部12电连接。中盖15设置于感测单元14相反于底部11的一侧。透镜16设置于中盖15相反于底部11的一侧并覆盖于感测单元14上,主要用以聚焦感测光线,以及划分感测区域(例如划分为明区、暗区)。遮片17设置于透镜16相反于底部11的一侧并包覆于透镜16之上,此外,为用以聚焦感测光线,透镜16有部分区域未被遮片17遮蔽。遮片17上具有多个折线供使用者自行折断,使用者可依据不同感测范围的需求折断部分遮片17。外盖18设置于遮片17相反于底部11的一侧。本技术领域的通常知识者应可了解其组成及原理。
本发明的自动校正方法,请参阅图2及图3A的实施例流程图。本实施例的流程及其定义的方程式/演算法,可以软件或硬件的方式写入至上述感测单元14(例如与其连接的控制电路板(图未示出)上的运算单元)中,用以控制被控设备。
自动校正方法较佳包含下列步骤:(A1)设定预设触发值;(A2)取样信号并累积信号值以进行信号判断;(A3)确认是否达到触发条件;(A4)若是,则记录达到触发条件的累积信号值,若否,则回到步骤(A2);(A5)分析并更新该预设触发值。
步骤(A1)设定预设触发值,此步骤较佳执行于感测器1处于暖机的状态下。详细来说,当感测器1被开通,即感测单元14通电且功能(例如I/O输入输出)稳定之后,执行步骤(A1-1)取样感测单元的基准电压V1。接着执行步骤(A1-2)依据基准电压V1与电路设计在一定时间内(Δt,本实施例以100~250ms为例,但不以此为限)设定感测器在暖机状态下取得的初始环境感测信号值S1。具体而言,S1可定义为下列关系式:
S1=∫∣(V-V1)∣dt,
其中V为在Δt时间内所取得的代表环境的电压的感测单元的单点电压。
须说明的是,设定初始环境感测信号值S1需同时考量基准电压V1与上述单点电压V。基准电压包含有环境因素。主要为了适应操作环境及安装方式。然而,其数值会因不同的操作环境及安装方式而有所不同。安装方式大致可分为入墙式(in-wall)、壁挂式(wall-mount)及吸顶式(ceiling),但不以此为限。
继续执行步骤(A1-3)依据基准电压V1,取得初始触发值S2。其关系式如下:S2=S1+Sdef,其中Sdef为预设的触发经验值。Sdef依不同设备会有不同的经验数值。在此暖机状态下,通过上述流程而定义出预设触发值Swin=S2。在此实施例中,预设触发值可视为感测器1的最高感度。
在暖机完成后,即开始执行人体移动侦测及自我学习的阶段。执行步骤(A2)取样信号并累积信号值以进行信号判断。例如,每隔一段时间进行取样。举例来说,每隔Δt时间(例如每隔100~250ms等)取样n(例如n=150)点,关系式如下:St=∫∣(V-V1)∣dt,其中V为在Δt时间内取得的感测单元的单点电压,如图3B所示。
信号取样完成后,执行步骤(A3)确认是否达到触发条件,如达到触发条件则进行步骤(A4)记录达到触发条件的累积信号值:
St=∫∣(V-V1)∣dt≥V1·t。如图3C所示,当信号超过预设触发值(Swin)时即判定为触发,系统依上述演算法进行运算。需说明的是,为避免将未触发(即介于Swin与V1·n之间的区域)的数据纳入计算,在计算时需限制条件,即≥V1·n。
承上,继续执行步骤(A5)分析并更新该预设触发值。具体来说,为在一定时间内成功触发N1次(以10次为例,但不以此为限),在实际情况下,可视为感测器在一定时间内侦测到物体在感测范围内触发N1次。
进行步骤(A5-2)删除相对远离该平均值的数笔数据。主要针对感测距离做分析与修正。举例来说,从中删除K1笔相对远离平均值Savg的数据,剩下M1笔数据。其目的在于,过滤掉感测器在感测时所得到相对远的距离数值,用以降低误判率。并且,每次过滤数据都须重新计算Savg,亦即,数据每次过滤K1笔,剩下M1笔数据,如此持续循环过滤,最后剩下的M1笔数据小于等于Kmin笔时,即可得到修正距离后的感测值Sadj,其中Kmin为数据过滤后所剩下的最少笔数据。其关系式定义如下:
前述步骤(A5-2)删除相对选择该平均值的数笔数据,请一并参考图3D,举例而言,目前感测到有20笔数据储存到阵列S,S中包含(S1~S20),过滤(删除)K1=6笔数据后剩下M1=20-K1笔数据,即M1=14笔最靠近平均值的数据。持续过滤6笔(14→8→2)直至M1=2笔(即K1≥Kmin=2)最靠近平均值的数据(以S3及S8为例)。此外,假设系统目前感测到另一数据数值S21相对S3更靠近Savg时,系统会自动将S3数据排除并将S21纳入,此时Savg也会对应变动,例如变为Savg2。依此,即可得到最即时且最靠近的Kmin笔数据。
通过上述关系式,进行步骤(A5-3)更新预设触发值。更新后的触发值定义为Swin=Sadj。
须说明的是,在步骤(A3)中,如判断未达到触发条件,则继续判断是否持续达到预设时间仍未触发(即,步骤A3-1)。如是,则进行步骤(A5);若否,则回到步骤(A2)。
本发明的另一实施例,在实际情况下,为感测器1在安装完成后使用者即离开,亦即,感测器1可能无法在上述Tm1时间内达到N1次触发。然而,即便使用者离开,感测器1仍必需保有其功用。因此,感测单元14会以最高感度持续运作并进行以下流程。
接着进行步骤(A5-2)删除相对远离该平均值的数笔数据。主要针对感测距离做分析与修正。举例来说,从中过滤相对远离平均值Savg的K2笔数据,而后剩下M2笔数据。其目的在于,过滤掉感测器在感测时所得到相对远的距离数值,用以降低误判率。数据每次过滤K2笔,剩下M2笔数据,如此持续循环过滤,最后剩下的M2笔数据小于等于Kmin笔时,即可得到修正距离后的感测值Sadj,其中Kmin为数据过滤后所剩下的最少笔数据。其关系式定义如下:
前述步骤(A5-2)删除相对远离该平均值的数笔数据,也请参考图3D,其细节不在此赘述。
通过上述关系式,进行步骤(A5-3)取得该数笔数据的平均值用以更新该预设触发值。类似地,更新后的触发值定义为Swin=Sadj。
相较于现有技术,本发明的感测器的自动校正方法,能使感测器具有自我学习的功能,持续进行自我校正,能有效地省去耗时且繁复的手动调整作业。
