具体实施方式
图1为本申请实施例提供的一种在离床与体动监测系统的结构示意图，参考图1，该在离床与体动监测系统包括：在离床与体动监测床垫110、光发生器111、光接收器112和比较电路114；在离床与体动监测床垫110包括光纤导线结构113、第一垫层115和第二垫层116；光纤导线结构113位于第一垫层115与第二垫层116之间；光发生器111与光纤导线结构113的第一端连接，光发生器111设置为发射第一光信号并将第一光信号输入至光纤导线结构113的第一端；光接收器112与光纤导线结构113的第二端连接，光接收器112设置为接收光纤导线结构113的第二端输出的第二光信号；比较电路114与光接收器112连接，比较电路114设置为获取光接收器112接收的第二光信号，并将第二光信号转换为光功率值，并将光功率值分别与异常体动基准值和离床基准值进行比较并输出比较结果。
示例性的，光发生器111在不同时刻发射的第一光信号都是相同的，用户躺在在离床与体动监测床垫110上时，用户可以与第一垫层115接触或与第二垫层116接触。本实施例以用户与第一垫层115接触为例进行说明，用户躺在在离床与体动监测床垫110上且与第一垫层115接触时，第一垫层115会受到用户施加的压力，位于第一垫层115一侧的光纤导线结构113也会受到压力而 发生形变，当光纤导线结构113发生形变时，光发生器111输出的第一光信号的光强等参数将在光纤导线结构113内将发生变化，因此，光纤导线结构113的第二端输出的第二光信号与第一光信号将不同。
光接收器112设置为接收第二光信号，比较电路114可以将获取到的第二光信号转化为光功率值，用户躺在在离床与体动监测床垫110上的光功率值与用户离开在离床与体动监测床垫110上的光功率值是不同的，比较电路114可以检测所获取的第二光信号对应的光功率值与离床基准值的大小，示例性的，当用户躺在在离床与体动监测床垫110上时，比较电路114检测出其所获取的第二光信号对应的光功率值大于离床基准值，当用户离开在离床与体动监测床垫110后，比较电路114检测出其所获取的第二光信号对应的光功率值小于离床基准值，因此，可以根据第二光信号对应的光功率值与离床基准值来判断用户是否离开在离床与体动监测床垫110。用户离开在离床与体动监测床垫110有可能是意外跌床，因此，可以根据比较结果判断用户是否发生意外跌床。
用户躺在在离床与体动监测床垫110上且身体不发生异动的光功率值与用户躺在离床与体动监测床垫110上且身体发生异动的光功率值是不同的，比较电路114可以检测其所获取的第二光信号对应的光功率值与异常体动基准值的大小，示例性的，当用户躺在在离床与体动监测床垫110上且身体不发生异动时，比较电路114检测出其所获取的第二光信号对应的光功率值大于异常体动基准值，当用户躺在离床与体动监测床垫110上且身体发生异动时，比较电路114检测出其所获取的第二光信号对应的光功率值小于异常体动基准值，因此，可以根据第二光信号对应的光功率值与异常体动基准值的大小来判断用户是否有异常体动，异常体动包括意外拔管，示例性的，若用户的胳膊发生移动而将氧气管意外拔掉时，可以根据比较结果来判断用户是否发生异常体动。
另外，比较电路114也可以计算多组连续的第二光信号对应的光功率值的标准差，将标准差与第一标定值进行对比输出异常体动的信号，比较电路114输出异常体动信号表示用户存在异常体动，示例性的，当标准差小于第一标定 值时，比较电路114输出异常体动信号。比较电路114还可以计算多组连续的第二光信号对应的光功率值的平均值，将平均值与第二标定值进行对比，输出用户的在、离床信号，比较电路114输出离床信号，表示用户已离开在离床与体动监测床垫110，示例性的，当平均值小于第二标定值时，比较电路114输出离床信号。本实施例中的第一标定值和第二标定值的大小可以根据实际需求进行设置。
需要说明的是，光发生器111、光接收器112和比较电路114可以设置于在离床与体动监测床垫110左上角。图1只是示例性的画出光纤导线结构113的尺寸小于第一垫层115的尺寸和第二垫层116的尺寸，以及示例性的画出第一垫层115的尺寸小于第二垫层116的尺寸，图1所示的结构并非对本申请的限定，在实际应用中，可以根据实际需求设置光纤导线结构113的尺寸、第一垫层115的尺寸和第二垫层116的尺寸。
本申请实施例提供一种在离床与体动监测系统，在离床与体动监测系统中包括在离床与体动监测床垫、光发生器、光接收器和比较电路，在离床与体动监测床垫包括光纤导线结构、第一垫层和第二垫层，光纤导线结构位于第一垫层与第二垫层之间，光发生器输出第一光信号至光纤导线结构的第一端，当用户施加在在离床与体动监测床垫上的压力不同时，光纤导线结构的第二端输出的第二光信号将不同，且第二光信号与第一光信号不同，比较电路从光接收器中获取第二光信号并将第二光信号对应的光功率值分别与异常体动基准值和离床基准值进行比较并输出比较结果，工作人员可以根据比较结果判断用户的是否离床以及用户是否发生异常体动。本申请实施例提供的一种在离床与体动监测系统，可以监测用户的在、离床情况以及异常体动情况。
可选的，图2为本申请实施例提供的又一种在离床与体动监测系统的结构示意图，参考图2，比较电路114包括处理器11、第一比较器12和第二比较器13；处理器11与光接收器112、第一比较器12的第一输入端和第二比较器13的第一输入端连接，处理器11设置为获取光接收器112接收的第二光信号，并 将第二光信号转换为电信号，并根据电信号得到引起光纤导线结构发生形变的光功率值，并将光功率值分别发送至第一比较器12的第一输入端和第二比较器13的第一输入端；第一比较器12的第二输入端设置为输入异常体动基准值，第一比较器12设置为比较光功率值与异常体动基准值大小，并输出第一比较结果；第二比较器13的第二输入端设置为输入离床基准值，第二比较器13设置为比较光功率值与离床基准值的大小，并输出第二比较结果。
示例性的，当光功率值大于异常体动基准值时，可以设定第一比较器12的输出端输出第一高电平信号，当光功率值小于或等于异常体动基准值时，第一比较器12的输出端输出第一低电平信号，可以根据第一比较器12的输出端输出的电平信号的高低来判断用户是否有异常体动。当光功率值大于离床基准值时，可以设定第二比较器13的输出端输出第二高电平信号，当光功率值小于或等于离床基准值时，第二比较器13的输出端输出第二低电平信号，可以根据第二比较器13的输出端输出的电平信号的高低来判断用户的在离床情况。还需要设定第一比较器12的第一输入端输入的光功率值小于或等于离床基准值时，第一比较器12不输出电平信号。
可选的，光纤导线结构113为网状。
示例性的，光纤导线结构113可以为微弯的网状结构，光纤导线结构113为网状时易发生形变，灵敏度更高，即使用户的身体发生微弱的变动，光纤导线结构113也能发生微弯，光纤导线结构113中多区域发生微弯，会使光纤导线结构113中的光信号损耗增大，使比较电路114得到的光功率值将更精确，从而可以更准确地分析出用户的在、离床情况以及异常体动情况。
