该光电检测电路两个光源与所述测试条的测试区和空白区位置相应，能够发出与所述测试条的测试区和空白区相应的光；光检测器能够接收来自测试区和空白区的反射光线；所述两个光源所发出的光照射到测试条的测试区和空白区，并反射经由所述光检测器接收，然后反馈检测信息给处理器。该方案只需两个光源和一个光检测器，结构简单、成本低、功耗低，且光源充足、光反射效果好。
请结合参阅图5~8，该前导通电极8、9连接电路板7上前电触片15、16，以及连接吸水棒6并通过吸水棒连接检测试纸5的样本接受区域23；该后导通电极10、11连接电路板7上后电触片17、18和检测试纸5的吸水区域25。
采用本发明分析检测装置进行化验物分析，首先通过吸水棒吸取待化验液体，液体经吸水棒流向检测试纸，接通光电检测电路，同时经过检测试纸的液体会接通导通装置，连接电路板的导通装置会将接通信号反映给处理器，光电检测电路读取检测数据并经由处理器分析判断出结果。处理器接收到导通装置的导通信号即表示该检测试纸上样过程完整，检测结果为有效，如果在规定时间内，后导通电极未导通，无导通信号传给处理器存储，即表示该检测试纸上样过程不完整，此结果无效。该装置除了可以电子化检测分析化验物，同时可以感应到吸水区域湿度从而确定检测试纸是否上样，具有更高的检测准确度，减少检测误差。
请结合参阅图9~11，本发明还提供一种分析检测方法，其采用如上所述的带湿度感应功能的分析检测装置，该分析检测装置的处理器设有检测对比的阈值，该分析检测包括如下步骤：
（1）分析检测装置的吸水棒6吸收待检测的液体样本，并经由检测试纸流动传送，当液体样本流经前端导通电极8、9使其导通，光电检测电路启动检测程序，否则输出结果三；
（2）光电检测电路启动检测程序，两个光源交替发光，光电检测电路对检测试纸的检测区24进行检测，根据检测值与阈值对比结果进行判断并输出结果：
若液体样本流经后导通电极10、11使其导通，且检测值大于等于阈值，则输出结果一；
若液体样本流经后导通电极10、11使其导通，且检测值小于阈值，则输出结果二；
若液体样本没有使后导通电极10、11导通，则输出结果三。
输出结果可有多种显示方式或提示方式，可以在显示屏中显示结果，如采用图像或文字显示，在一些实施例中，所述结果一为“Pregnant”，结果二为“NotPregnant”，结果三为“Error”；也可以采用指示灯表示结果，例如采用不同颜色的指示灯显示三种不同结果；也可以采用声音表示结果，例如蜂鸣声或语音。
具体地，吸水棒6吸收到足够的液体样本，前导通电极8、9接触到液体导通，导通电流信号经前电触片15、16传递给微处理器22，显示屏显示等待的漏斗图样。
电路板检测程序启动，光源12、13间歇发光，光感单元14也启动检测,蜂鸣器19响几声，在规定间歇时间内光感单元14不断测试变化值；同时检测试纸5的样本接受区域23接受到液体样本，进而液体流动至检测区域24，再流动到吸水区域25，液体流到吸水区域25的同时，后端导通电极10、11接触到液体导通，电流信号经后电触片17、18传递给微处理器22，蜂鸣器19响几声，微处理器22并记忆存储此信号。
如果液体样本含有被检测物质，则测试区241显色，光感单元14检测显色变化值大于或等于设定值，且规定时间内后导通电极10、11接触到液体导通，微处理器22存储到后端导通信号，则显示屏21显示“Pregnant”，蜂鸣器19响几声，如果规定时间内后导通电极10、11没有接触到液体，微处理器22未存储到后端导通信号，则显示屏21显示“Error”，蜂鸣器19响几声；液体样本无被检测物质，则测试区241不显色或光感单元14检测显色变化值小于设定值，且规定时间内后导通电极10、11接触到液体导通，微处理器22存储到后端导通信号，显示屏21则显示“NotPregnant”，蜂鸣器19响几声, 如果规定时间内后导通电极10、11没有接触到液体，微处理器22未存储到后端导通信号，则显示屏21显示“Error”，蜂鸣器19响几声。
本实施例中，处理器设置有相应的信号存储模块用以存储检测信号和导通信号，时控模块用以控制检测时序，数据比较模块用以将检测值与预设值进行比较并且与设定值模块连接，语音控制模块用于语音提示，显示逻辑控制模块用以显示检测结果。
以上所述仅为本发明的较佳实施例，本发明的保护范围并不局限于此，任何基于本发明技术方案上的等效变换均属于本发明保护范围之内。
