在其中一个实施例中，弹性柱包括弹簧、外壳和调节件，弹簧在位于外壳内，一端抵紧外壳的端部，另一端抵紧调节件；
调节弹簧初始压力时，需要变大初始压力，调节件向压缩弹簧方向移动，促使弹簧压缩，进而提高弹簧的初始压力。
在其中一个实施例中，弹性柱还包括内筒和柔线，外壳和内筒套合，弹簧在外壳和内筒之内，柔线连接外壳和内筒，致使外壳和内筒之间组合体最大长度不变。
在其中一个实施例中，弹簧的弹性系数为K，最小初始压力为Fmin；需要调节的弹簧压缩量为Ln；根据预处理数据分析，得出其中一根弹性柱的实际初始压力要调节为Fn，根据公式，Ln＝(Fn-Fmin)/K，算出弹簧压缩量Ln，调节件向压缩弹簧的方向移动距离Ln；根据上述公式和预处理数据，对应调节出每根弹簧压缩量Ln。
在其中一个实施例中，被测者站立在体重采集器上，体重采集器上还设置有测高杆，测高板在测高杆上滑动，测出人体身高；
轮廓采集器在体重采集器的底部滑动，轮廓采集器包括测量板和分布在所述测量板上的多根测距柱，测距柱顶部有凸头，推动轮廓采集器向人体压迫时，测距柱的凸头抵在人体上，测距柱的长度被压缩，众多的测距柱在测量板上分为A区和B区布置；
处理中心包括A区测距单片微计算机电路、B区测距单片微计算机电路、模拟床单片机微计算机电路；
设置A区测距单片微计算机电路和B区测距单片微计算机电路；A区单片机U1逐个选通A区的测距电路单元，由A区单片机U1第36脚发送测距脉冲，从第37脚接收返回脉冲，计算出A区各测距柱的高度；B区单片机U2逐个选通B区的测距电路单元，由B区单片机U2第36脚发送测距脉冲，从第37脚接收返回脉冲，计算出B区各测距柱的高度；A区单片机U1的串口1与B区单片机U2的串口1连接，将A区所有测距柱的高度数据传输给B区单片机U2的存储器U11存储；
在A区单片机U1的A区程序存储器中装载A区测距柱片选程序模块、A区测距柱初始化程序模块、A区测距程序模块、A区测距显示程序模块、与B区通信程序模块、A区键盘管理程序模块，以上各个程序模块都可以由A区主处理器调用执行；在B区单片机U2的B区程序存储器中装载B区测距柱片选程序模块、B区测距柱初始化程序模块、B区测距程序模块、B区测距显示程序模块、与A区通信程序模块、B区键盘管理程序模块、统一存储程序模块、与弹性驱动板通信程序模块，以上各个程序模块都可以由B区主处理器调用执行；
弹性柱包括弹簧通过电机驱动调节弹簧压缩量初始压力，在弹性柱单片机U4的U4程序存储器中装载与模拟床单片机通信程序模块、压力A/D转换程序模块、电机驱动程序模块、自检程序模块，以上各个程序模块都可以由模拟床主控处理器调用执行；
模拟床在弹性柱的最底部设置压力传感器IC6,一个压力传感电路输出压力模拟电压V0到弹性柱压力检测电机驱动电路，电路中的检测驱动单片机U4的一个P1口的引脚连接压力模拟电压V0；在弹性柱之中，一个电机坐落在压力传感器IC6之上，压力传感器IC6感知经电机传递过来的压力；
电机受检测驱动单片机U4的驱动进行正转和反转，进而控制弹性柱初始压力大小；
在弹性柱压力检测电机驱动电路中设置RS485通信接口MAX487芯片，该芯片连接检测驱动单片机U4的串口和模拟床单片机U3的串口2，检测驱动单片机U4的一组接口连接拨码开关构成的站号设置电路，当模拟床单片机U3发来该站号的驱动数据时，检测驱动单片机U4根据驱动数据驱动电机工作，压迫弹簧，同时，反向的压力施加在传感器IC6之上，压力传感电路输出增大的压力电压V0，检测驱动单片机U4的P1口内部的A/D转换器将模拟电压转为数字数据，经比较，外来数据与本地A/D转换数据相近时，电机停止工作；
当所有弹性柱的初始压力都设定结束后，模拟床单片机U3连接的弹性显示单元显示各个弹性柱的初始压力设定状态，此时，被被测者到模拟床上体验舒适程度，主观提出改进要求，此时通过弹性命令键盘电路和弹性数据键盘电路输入改进数据，改变相关部位弹性柱的初始压力，至被被测者满意，并记录最终数据，存入SD卡之中。
人体卧姿数据采集系统包括体重采集器，用于采集被测者的体重数据；
轮廓采集器，用于采集被测者的背部轮廓数据；
体重采集器或轮廓采集器至少之一设置有身高采集功能，用于采集被测者的身高数据；
控制台，处理中心位于控制台内，用于接收体重数据、背部轮廓数据和身高数据，并对接收体重数据、背部轮廓数据和身高数据进行预处理，形成预处理数据；

本发明所提供的技术方案具有以下的优点及效果：
利用体重采集器和轮廓采集器采集被测者的体重和轮廓数据，也同时采集被测者的身高数据，这些数据获取后在处理中心中进行预处理，然后模拟床接收到该数据，用于调节弹性柱初始压力。调节后的弹性柱初始压力不同位置会有所不同，如人体臀部位置，躺下时，要将弹性柱压缩更多，这时，将该部分的弹性柱的初始压力设置较小，而人体腰部位置，躺下时，弹性柱的压缩量小，所以为了确保被测者躺下后，各弹性柱承受的力度相接近，所以将腰部位置的初始压力调节较大，将臀部初始压力调节较小，所以被测者躺下后身体各个部位受力相接近，再根据被测者的主观体验，进行调节，达到被测者合适的软硬度，然后存储个性化床垫数据。此时的个性化床垫数据再发送到工厂加工。

如图1至图7所示，人体卧姿数据采集系统，包括：
体重采集器10，用于采集被测者的体重数据；轮廓采集器，用于采集被测者的背部轮廓数据；体重采集器10或轮廓采集器至少之一设置有身高采集功能，用于采集被测者的身高数据；控制台40，处理中心位于控制台40内，用于接收体重数据、背部轮廓数据和身高数据，并对接收体重数据、背部轮廓数 据和身高数据进行预处理，形成预处理数据；模拟床50，根据预处理数据，将弹性柱52调节出指定的初始压力，提供给被测者体验舒适度。
而具体在本实施例中，身高采集器包括测高杆20和测高板30，测高杆20安装在体从体重采集器10上，测高板30在该测高杆20上移动，用于接触被测者的头部，完成身高的检测。体重采集器10和轮廓采集器之前是集成一体，在被测者站立在体重采集器10上后就可以实现轮廓采集器的数据采集。而在身高采集器上表面有称重台11和滑道12，其中滑道12与轮廓采集器配合。
轮廓采集器包括测量板13和分布在所述测量板13上的多根测距柱131。
模拟床50包括弹性柱52、承接板51和外罩53，弹性柱52安装在承接板51上，外罩53覆盖弹性柱52。弹性柱52包括弹簧521、外壳522、内筒524、柔线525和调节件523，弹簧521在位于外壳522内，一端抵紧外壳522的端部，另一端抵紧调节件523。而具体地，外壳522套合在内筒524的外侧，内筒524可以伸入至外壳522内，而弹簧521位于外壳522和内筒524内。调节件523包括电机5231、螺杆5232和螺纹板5233，电机5231驱动螺杆5232转动，螺纹板5233跟随移动，通过电机5231控制顺时针或逆时针转动，实现螺纹板5233向上移动或向下移动，即可以向上压缩弹簧521，向下释放弹簧521。
如图1至图7所示，人体卧姿数据采集方法，包括如下步骤：
被测者站立在体重采集器10上，体重采集器10采集被测者的体重数据；
被测者站立，轮廓采集器采集被测者的背部轮廓数据；
被测者身高数据在所述体重采集器10或所述轮廓采集器上采集；
处理中心接收到所述体重数据、背部轮廓数据和身高数据，处理中心对所述体重数据、背部轮廓数据和身高数据进行预处理，并将预处理后的预处理数据发送至模拟床50；
模拟床50接收到预处理数据，根据预处理数据，对模拟床50内的多根弹性柱52的初始压力调节；
被测者躺上调节后的模拟床50，并根据被测者主观描述，对模拟床50进行调节，至被测者合适；
处理中心采集被测者合适后的模拟床50调节数据。
利用体重采集器10和轮廓采集器采集被测者的体重和轮廓数据，也同时采集被测者的身高数据，这些数据获取后在处理中心中进行预处理，然后模拟床50接收到该数据，用于调节弹性柱52初始压力。如图4所示，调节后的弹性柱52初始压力不同位置会有所不同，如人体臀部位置，躺下时，要将弹性柱52压缩更多，这时，将该部分的弹性柱52的初始压力设置较小，而人体腰部位置，躺下时，弹性柱52的压缩量小，所以为了确保被测者躺下后，各弹性柱52承受的力度相接近，所以将腰部位置的初始压力调节较大，将臀部初始压力调节较小，所以被测者躺下后身体各个部位受力相接近，再根据被测者的主观体验，进行调节，达到被测者合适的软硬度，然后存储个性化床垫数据。此时的个性化床垫数据再发送到工厂加工。
如图1和图2所示，体重采集器10、轮廓采集器集成一体，被测者在采集体重数据，身高数据也进行采集，背部轮廓数据也在轮廓采集器中采集。
测量板13和被测者站立板相对移动，测距柱131接触到被测者的背部；测量板13移动到预设位置后停止移动，轮廓采集器获取测距柱131被压缩的位置数据。此时采集的数据为被测者背部轮廓的数据，即人体的个性化数据。
进一步地，测量板13向被测者背部移动，测距柱131逐步接触到被测者的背面轮廓，并被压缩，直至其中一根测距柱131被压缩到最大压缩量，测量板13停止移动；此时被测者身体正面投影范围内，所有测距柱131均与被被测者的身体接触，轮廓采集器获取测距柱131位置数据。达到最大压缩量后才停止移动测量板13，确保人体的背部轮廓完全被测距柱131接触到，采集的数据更加准确。
处理中心预处理数据包括，根据所述体重数据、背部轮廓数据和身高数据，计算出被测者人体体重的分布。该人体体重的分布可以为后续模拟床50上的弹性柱52调节提供数据支持。
调节弹簧521初始压力时，需要变大初始压力，调节件523向压缩弹簧521方向移动，促使弹簧521压缩，进而提高弹簧521的初始压力。因为人体在侧卧时，不同部位的凹陷程度不同，所以通过调节弹簧521的压缩量对弹性柱52的初始压力调节，满足人体侧卧时，各个部位受力大小均衡。
弹性柱52还包括内筒524和柔线525，外壳522和内筒524套合，弹簧521在外壳522和内筒524之内，柔线525连接外壳522和内筒524，致使外壳522和内筒524之间组合体最大长度不变。该设置即为保证弹性柱52的最长尺寸不变，所以在自然状态下，模拟床50的表面是平整的。
如图4至图5所示，具体弹性柱52的力度调控。弹簧521的弹性系数为K，最小初始压力为Fmin；需要调节的弹簧521压缩量为Ln；根据预处理数据分析，得出其中一根弹性柱52的实际初始压力要调节为Fn，根据公式，Ln＝(Fn-Fmin)/K，算出弹簧521压缩量Ln，调节件523向压缩弹簧521的方向移动距离Ln；根据上述公式和预处理数据，对应调节出每根弹簧521压缩量Ln。此时通过调节件523将弹簧521压缩Ln的长度，满足指定弹性柱52的调节。其余不同的弹性柱52根据预处理数据调节出指定的实际初始压力。
具体地，如图8至图24所示，
轮廓采集器在体重采集器10的底部滑动，轮廓采集器包括测量板13和分布在所述测量板13上的多根测距柱131，测距柱131顶部有凸头39，推动轮廓采集器向人体压迫时，测距柱131的凸头39抵在人体上，测距柱131的长度被压缩，众多的测距柱131在测量板13上分为A区和B区布置；

设置A区测距单片微计算机电路和B区测距单片微计算机电路；A区单片机U1逐个选通A区的测距电路单元31，由A区单片机U1第36脚发送测距脉冲，从第37脚接收返回脉冲，计算出A区各测距柱131的高度；B区单片机U2逐个选通B区的测距电路单元31，由B区单片机U2第36脚发送测距脉冲，从第37脚接收返回脉冲，计算出B区各测距柱131的高度；A区单片机U1的 串口1与B区单片机U2的串口1连接，将A区所有测距柱131的高度数据传输给B区单片机U2的存储器U11存储；
在A区单片机U1的A区程序存储器中装载A区测距柱131片选程序模块、A区测距柱131初始化程序模块、A区测距程序模块、A区测距显示程序模块、与B区通信程序模块、A区键盘管理程序模块，以上各个程序模块都可以由A区主处理器调用执行；在B区单片机U2的B区程序存储器中装载B区测距柱131片选程序模块、B区测距柱131初始化程序模块、B区测距程序模块、B区测距显示程序模块、与A区通信程序模块、B区键盘管理程序模块、统一存储程序模块、与弹性驱动板通信程序模块，以上各个程序模块都可以由B区主处理器调用执行；
弹性柱52包括弹簧521通过电机5231驱动调节弹簧521压缩量初始压力，在弹性柱52单片机U4的U4程序存储器中装载与模拟床50单片机通信程序模块、压力A/D转换程序模块、电机5231驱动程序模块、自检程序模块，以上各个程序模块都可以由模拟床50主控处理器调用执行；
模拟床50在弹性柱52的最底部设置压力传感器IC6,一个压力传感电路输出压力模拟电压V0到弹性柱52压力检测电机5231驱动电路，电路中的检测驱动单片机U4的一个P1口的引脚连接压力模拟电压V0；在弹性柱52之中，一个电机5231坐落在压力传感器IC6之上，压力传感器IC6感知经电机5231传递过来的压力；
电机5231受检测驱动单片机U4的驱动进行正转和反转，进而控制弹性柱52初始压力大小；
在弹性柱52压力检测电机5231驱动电路中设置RS485通信接口MAX487芯片，该芯片连接检测驱动单片机U4的串口和模拟床50单片机U3的串口2，检测驱动单片机U4的一组接口连接拨码开关构成的站号设置电路，当模拟床50单片机U3发来该站号的驱动数据时，检测驱动单片机U4根据驱动数据驱动电机5231工作，压迫弹簧521，同时，反向的压力施加在传感器IC6之上，压力传感电路输出增大的压力电压V0，检测驱动单片机U4的P1口内部的A/D 转换器将模拟电压转为数字数据，经比较，外来数据与本地A/D转换数据相近时，电机5231停止工作；
当所有弹性柱52的初始压力都设定结束后，模拟床50单片机U3连接的弹性显示单元显示各个弹性柱52的初始压力设定状态，此时，被被测者到模拟床50上体验舒适程度，主观提出改进要求，此时通过弹性命令键盘电路和弹性数据键盘电路输入改进数据，改变相关部位弹性柱52的初始压力，至被被测者满意，并记录最终数据，存入SD卡之中。

凸头39为弧形，舒适地与人体接触，钩孔391用于人工复位上柱筒；
反射面35用于反射超声波发生器33发出的超声波，超声波接收器34接收到超声波脉冲串后，测距电路单元31，将信号传输回A区单片机U1或B区单片机U2第37脚,计算出该测距柱131的高度，测距脉冲是从第36脚发出。
A区单片机U1或B区单片机U2每次从第36脚发出测距脉冲，只能检测一个测距柱131的高度，所以对63个测距柱131要顺序检测，片选工作由CD4066数字电路芯片完成，选通哪一个测距柱131，由A区单片机U1或B区单片机U2的一个I/O引脚输出高电平，该引脚连接的CD4066控制端打开该测距柱131与单片机第36脚的连接，A区单片机U1或B区单片机U2完成对该测距柱131的测量，将测距数据暂存在内存之中，关闭该测距柱131与A区单片机U1或B区单片机U2，再启动A区单片机U1或B区单片机U2下一个I/O引脚输出高电平，对下一个测距柱131进行测距。

    轮廓采集器在体重采集器的底部滑动，轮廓采集器包括测量板和分布在所述测量板上的多根测距柱，测距柱顶部有凸头，推动轮廓采集器向人体压迫时， 测距柱的凸头抵在人体上，测距柱的长度被压缩，众多的测距柱在测量板上分为A区和B区布置；
    处理中心包括A区测距单片微计算机电路、B区测距单片微计算机电路、模拟床单片机微计算机电路；
    设置A区测距单片微计算机电路和B区测距单片微计算机电路；A区单片机U1逐个选通A区的测距电路单元，由A区单片机U1第36脚发送测距脉冲，从第37脚接收返回脉冲，计算出A区各测距柱的高度；B区单片机U2逐个选通B区的测距电路单元，由B区单片机U2第36脚发送测距脉冲，从第37脚接收返回脉冲，计算出B区各测距柱的高度；A区单片机U1的串口1与B区单片机U2的串口1连接，将A区所有测距柱的高度数据传输给B区单片机U2的存储器U11存储；
    在A区单片机U1的A区程序存储器中装载A区测距柱片选程序模块、A区测距柱初始化程序模块、A区测距程序模块、A区测距显示程序模块、与B区通信程序模块、A区键盘管理程序模块，以上各个程序模块都可以由A区主处理器调用执行；在B区单片机U2的B区程序存储器中装载B区测距柱片选程序模块、B区测距柱初始化程序模块、B区测距程序模块、B区测距显示程序模块、与A区通信程序模块、B区键盘管理程序模块、统一存储程序模块、与弹性驱动板通信程序模块，以上各个程序模块都可以由B区主处理器调用执行；
    弹性柱包括弹簧通过电机驱动调节弹簧压缩量初始压力，在弹性柱单片机U4的U4程序存储器中装载与模拟床单片机通信程序模块、压力A/D转换程序模块、电机驱动程序模块、自检程序模块，以上各个程序模块都可以由模拟床主控处理器调用执行；
    模拟床在弹性柱的最底部设置压力传感器IC6,一个压力传感电路输出压力模拟电压V0到弹性柱压力检测电机驱动电路，电路中的检测驱动单片机U4的一个P1口的引脚连接压力模拟电压V0；在弹性柱之中，一个电机坐落在压力传感器IC6之上，压力传感器IC6感知经电机传递过来的压力；
    电机受检测驱动单片机U4的驱动进行正转和反转，进而控制弹性柱初始 压力大小；
    在弹性柱压力检测电机驱动电路中设置RS485通信接口MAX487芯片，该芯片连接检测驱动单片机U4的串口和模拟床单片机U3的串口2，检测驱动单片机U4的一组接口连接拨码开关构成的站号设置电路，当模拟床单片机U3发来该站号的驱动数据时，检测驱动单片机U4根据驱动数据驱动电机工作，压迫弹簧，同时，反向的压力施加在传感器IC6之上，压力传感电路输出增大的压力电压V0，检测驱动单片机U4的P1口内部的A/D转换器将模拟电压转为数字数据，经比较，外来数据与本地A/D转换数据相近时，电机停止工作；
    当所有弹性柱的初始压力都设定结束后，模拟床单片机U3连接的弹性显示单元显示各个弹性柱的初始压力设定状态，此时，被被测者到模拟床上体验舒适程度，主观提出改进要求，此时通过弹性命令键盘电路和弹性数据键盘电路输入改进数据，改变相关部位弹性柱的初始压力，至被被测者满意，并记录最终数据，存入SD卡之中。
  10. 人体卧姿数据采集系统，其特征在于，包括：
    体重采集器，用于采集被测者的体重数据；
    轮廓采集器，用于采集被测者的背部轮廓数据；
    体重采集器或轮廓采集器至少之一设置有身高采集功能，用于采集被测者的身高数据；
    控制台，处理中心位于控制台内，用于接收体重数据、背部轮廓数据和身高数据，并对接收体重数据、背部轮廓数据和身高数据进行预处理，形成预处理数据；
    模拟床，根据预处理数据，将弹性柱调节出指定的初始压力，提供给被测者体验舒适度。
