具体实施方式
以下结合附图对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
本发明实施例提供基于传感器判断读写状态的方法，如图1所示，包括：
步骤1：基于智能手表中的测量传感器，获得所述智能手表相对于水平面的倾斜角度；
步骤2：根据获得的倾斜角度，判断佩戴所述智能手表的目标用户的目标手臂的放置状态，进而判断所述目标用户是否处于读写状态，并对判断结果进行记录；
步骤3：同时，将判断结果传输到与目标用户的智能手表进行绑定的家长端和教师端进行显示；
其中，所述测量传感器包括：加速度传感器、陀螺仪传感器、电子罗盘传感器、角度传感器和磁传感器中的任一种或多种。
上述目标用户是学生；
上述加速度传感器可以检测交流信号以及物体的振动，人在走动的时候会产生一定规律性的振动，而加速度传感器可以检测振动的过零点，从而判断目标用户处于非读写状态。
其中，如果，在使用加速度传感器在进行倾斜角度检测的过程中，受到运动加速度的影响，使得测量的倾斜角度不够准确时，可以利用陀螺仪传感器、电子罗盘传感器、角度传感器或磁传感器等传感器对倾斜角度进行补偿处理，使其倾斜角度更加准确，以此来判断目标用户的读写状态。
例如，如果倾斜角度不在预设角度范围内，如：预设角度范围是基于水平桌面的[0°，90°]，当目标用户的手部水平放置在水平桌面时，为0°，当用户的肘部垂直支撑在水平桌面时，为90°；
上述家长端和教师端，也可以是智能手表，还可以是智能手机、笔记本等电子设备。
上述技术方案的有益效果是：通过设置的测量传感器，便于确定用户的读写状态，通过将其传输到家长端，便于家长及时了解用户的学习情况。

当所述目标用户佩戴的所述智能手表中的所述加速度传感器检测出存在振动过零点时，判断所述目标用户处于非读写状态。

    其中，
    Figure PCTCN2020121454-appb-100003
    为检验统计量，Φ为感应磁通量，ω为正确佩戴所述智能手表时的感应磁通量；
    步骤4、判断佩戴有所述智能手表的目标用户是否正确佩戴所述智能手表；
    当检验统计量在预设阈值范围内，则称所述目标用户正确佩戴所述智能手表，否则继续执行步骤5；
    步骤5、计算错误偏差；
    Figure PCTCN2020121454-appb-100004
    其中，θ为错误偏差值，Φ为感应磁通量，ω为正确佩戴所述智能手表时的感应磁通量；
    步骤6、确定所述目标用户是取下所述智能手表还是未正确佩戴所述智能手表；
    当错误偏差值
    Figure PCTCN2020121454-appb-100005
    时，则确定佩戴有所述智能手表的目标用户取下所述智能手表；当错误偏差值
    Figure PCTCN2020121454-appb-100006
    时，则确定佩戴有所述智能手表的目标用户未正确佩戴所述智能手表。
