图2为本发明优选实施例的一种小孩踢被子检测装置的框图，如图2所示，该检测装置包括：热电堆红外测温传感器101、弱信号放大和滤波单元102、信号变换单元103、中央处理器104、信号反馈回路处理单元105、机械转动与控制单元106、WIFI或蓝牙通信单元107和大容量存储单元108。
热电堆红外测温传感器101，设置为：感应目标温度信息信号，预处理后传输到下一级弱信号放大和滤波单元102。
弱信号放大和滤波单元102，设置为：接收所述热电堆红外测温传感器101输出的目标温度信息信号，将所述目标温度信息信号放大，然后滤掉特定频率的信号，尽可能保证有用的温度信号清晰无噪波干扰，获取到反映温度特性的温度信号，传输到下一级信号变换单元103。
信号变换单元103，设置为：将所述弱信号放大和滤波单元102获取的温度信号进行模数转换，转换成电信号。
中央处理器104，设置为：处理所述电信号，获取所述待测目标的温度数据，依据获取的所述待测目标的温度数据与预先获取的所述待测目标的温度数据对比分析，得到确定所述待测目标踢被子的信息。
信号反馈回路处理单元105，设置为：在所述中央处理器处理所述电信号失败情况下，调整所述弱信号放大和滤波单元放大温度信息信号的放大参数。

大容量存储单元108，设置为：存储所述中央处理器分析到的所述目标温度数据，用于对比分析出小孩踢被子的信息。
可选地，所述中央处理器104对获取到的电信号进行处理，看该电信号是否符合处理标准，如果符合，得到一个温度信息Ya，合并此时位置信息Xa，组成二维点(Xa，Ya)，并存储到一个设定的二维数组A[n][n]存储区间，所述存储区间位于所述大容量存储单元108中，其中，n为大于一的自然数。
若所述电信号不能够处理成温度数据，则通过所述信号反馈回路处理单元105，将信息反馈到弱信号放大和滤波单元102，设置新的放大器参数，直至所述电信号能够处理成温度数据。
可选地，所述中央处理器对获取到的电信号进行处理，看该电信号是否符合处理标准步骤如下：
a)所述温度信号模数转换后的电信号幅值符合正常范围区间[-1.5V,+1.5V]，其中，电信号的幅值范围可根据数模转换器(ADC)分辨能力来调整；
b)获取的所述待测目标的温度数据符合温度范围[30℃,42℃]。
可选地，所述中央处理器下发下一条控制指令，所述机械转动与控制单 元106带动所述热电堆红外测温传感器101转动一定角度a，获取所述热电堆红外测温传感器101视场位置的温度信息和位置信息，存储至二维数组A[n][n]，其中，a大小可设定。
存储区间数据到达n后，得到一组初步温度信息，所述中央处理器104依据这组温度信息，勾勒待测目标人体的位置。通过判断多点温度高的密集区域为人体头部，勾勒头部外形，选取头部左上角边缘位置作为实际检测起点位置。起点位置就是我们测目标温度的原始二维坐标点，后续控制机械转动与控制单元只需一直朝一个方向转动便可全部测试完成，无需正反方向多次来回转动。
可选地，将获取到的温度数据A[n][n]存储到所述大容量存储单元108中，可作为判断目标是否踢被子的参考数据。
可选地，以坐标原点为起点，所述中央处理器104下发控制指令，控制所述机械转动与控制单元106带动所述热电堆红外测温传感器101转动角度b，此时记录位置L1，得到新的温度信息T1，并将位置L1和温度信息T1存储到一个新存储区间二维数组B[i][i]中的缓冲区域B[1][1]，所述新的存储区间位于所述大容量存储单元108中。其中，b大小可设定，i为大于1的自然数。
所述中央处理器104再下发控制指令给所述机械转动与控制单元106，带动所述热电堆红外感应温度单元101转动到位置L2，得到温度信息T2，将位置L2和温度信息T2存储到二维数组B[i][i]中的缓冲区域B[2][2]。
存储区间数据到达i后，对存储区间B[i][i]的数据进行分析，获得目标区域温度分布数据。所述中央处理器104依据目标区域的温度数据，对区域内目标进行睡眠状态下的踢被子分析。
可选地，如有踢被子的情况，目标躯干部位：腹部及邻近区域温度会比预先获取的参考温度高，高于阀值1度以上且多次测量结果一致，可判断踢被子已经发生，则通过WIFI/蓝牙通信单元发送踢被子信息到绑定的移动终端，提醒有踢被子情况。如没有踢被子的情况，则中央处理器104定期进行巡航检测。参考数据是自该检测装置开机后热电堆红外测温传感器感应待测目标同一部位所预先获取的所述待测目标的温度数据。
本发明实施例的技术方案，运用红外测温原理，热电堆红外测温传感器获取目标温度信息，通过中央处理器对目标温度信息进行处理分析，获得目标是否盖被子的信息，并发送至与所述检测装置绑定的移动终端。检测过程小孩无需佩戴任何物件，不产生任何辐射，检测过程不受小孩睡姿影响，识别准确率高，轻松实现检测功能。
