体重检测装置是生活中觉见的设备，人们常常使用它对自己的身体健康数据进行监测。
现有的体重检测装置(例如：体脂秤、体重秤等)都是通过其底部脚垫(托盘)施加压力给传感器，该传感器发生弹性形变，从而使阻抗发生变化，同时使用激励电压发生变化，输出一个变化的模拟信号，该信号经放大电路放大输出到模数转换器，转化为数字信号，再经过CPU处理得出体重值。
现有技术中只是对传感器的返回值做处理，从而得出体重值。若体重检测装置放置于在不合适的位置(例如：放置于地毯等较软的地面、放置不平衡等情况)时，不能很好地规避外界因素对它产生的影响，从而使传感器的返回值有误，产生的体重值有误。因此，现有的体重检测装置的测量精度较低，用户体验较差。

具体实施方式
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对照附图说明本发明的具体实施方式。显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图，并获得其他的实施 方式。
为使图面简洁，各图中只示意性地表示出了与本发明相关的部分，它们并不代表其作为产品的实际结构。另外，以使图面简洁便于理解，在有些图中具有相同结构或功能的部件，仅示意性地绘示了其中的一个，或仅标出了其中的一个。在本文中，“一个”不仅表示“仅此一个”，也可以表示“多于一个”的情形。
在本发明的一个实施例中，如图1所示，一种体重检测装置的测量方法，其特征在于，包括：
步骤S100当接收到第一操作时，获取各(体重检测装置底部的)支撑部在竖直方向上的加速度值；
其中，第一操作可以理解为使用体重检测装置的操作，例如：用户站在体重检测装置上想进行称量，或者，通过手机向体重检测装置发送了使用请求等操作，并站在体重检测装置上时。
步骤S200当各支撑部对应的竖直方向上的加速度值不都位于预设加速度范围内时，(则认为体重检测装置位于软质地面)控制各所述支撑部中的伸缩结构伸出；
其中，当各支撑部对应的竖直方向上的加速度值都位于预设加速度范围内时，测量得到用户的称量信息。
软质地面包括：放置了地毯、泡沫塑料等软性材料的地面；因体重检测装置不直接与硬质地面接触，其实质是放置在软质地面(例如：铺着地毯的地板)上，因此，测量结果会有一定的误差。硬质地面包括：地板、水泥地、瓷砖等硬质材料的地面。
每个支撑部都会有一个相应的加速度传感器，当用户站在体重检测装置上时，通过加速度传感器来获取各支撑部对应的竖直方向上的加速度值。
当支撑部位于软质地面时，用户站在体重检测装置上，当体重检测装置受到用户的压力时，软质地面会对体重检测装置一个反弹的力，从而使支撑部获取的加速度值与体重检测装置在硬质地面上获取的加速度值有 变化。
当支撑部位于硬质地面时，支撑部对应的竖直方向上的加速度值就是9.8(m/s2)，考虑到各加速度传感器的误差，因此，设置了预设加速度范围，例如：误差为±0.5，预设加速度范围可以为9.3-10.2，可以包含端点值。
当各支撑部对应的竖直方向上的加速度值位于此预设加速度范围时，说明各支撑部都放置于硬质地面上，因此，不需要后续的校正工作，直接进行测量用户的称量信息即可。
当各支撑部对应的竖直方向上的加速度值不都位于此预设加速度范围时，说明至少有一个支撑部是位于软质地面上的，因此，需要控制各支撑部的伸缩结构伸出，进行校正工作。
步骤S300获取各所述支撑部在所述伸缩结构伸出过程中竖直方向上的动态加速度值；
其中，伸缩结构伸出过程是指伸缩结构从伸出开始，到受到无法穿透的阻碍结束继续伸出并维持当前的伸出状态的这段时间中的动态加速度值。动态加速度值是指这段时间内几个加速度值组成的动态加速度值，例如：加速度传感器测量频率为50次/秒，伸缩结构伸出过程的时间为0.5秒，那么动态加速度值就是由25个加速度值组成。
受到无法穿透的阻碍可以理解为，例如：体重检测装置位于地毯上时，伸缩结构要穿透地毯，与地板直接接触，那么地毯较软的质地使伸缩结构可以穿透，因此伸缩结构的伸出过程不算结束，而穿透地毯后碰到地板时，伸缩结构无法再穿透地板，因此，碰到地板后伸出过程就结束了。当然，有的软质地面的材料伸缩结构可能也无法穿透，例如：泡沫塑料，原因为：1)碍于体重检测装置的体积，伸缩结构并不是无限长的，可能无法完全穿透泡沫塑料；2)考虑到不损伤地板等问题，伸缩结构与软质地面接触的部分可能仅仅是平面或具有圆滑过渡的尖端，穿刺能力并不是很强；因此，在碰到软质地面也无法穿透时，也认为伸出过程结束。
步骤S400根据各所述支撑部对应的竖直方向上的动态加速度值，执 行相应的操作。
其中，碰到硬质地面时的动态加速度值和碰到软质地面时的动态加速度值是不一样的，因此，可以通过此来判断是否校正成功，从而执行后续相应的操作。
具体的，本实施例中，当用户使用体重检测装置时，会先判断体重检测装置是否位于软质地面，若是的话，会伸出伸缩结构执行校正，在判断是否校正成功后，再执行相应的操作，保证了用户的称量信息是体重检测装置经过校正后测量得到的，称量信息更准确，提高了用户的使用体验。
优选地，步骤S400包括：步骤S410当各所述支撑部对应的竖直方向上的动态加速度值都趋于并稳定于所述预设加速度范围内时，(则认为体重检测装置已经校正完毕，此时体重检测装置位于硬质地面，因此，可以)测量得到用户的称量信息。
具体的，伸缩结构在刺穿软质地面时，支撑部竖直方向上的加速度值是小于位于硬质地面时的加速度值的，例如：以9.3为基准值，在刺穿软质地面时会小于9.3，其在接触到硬质地面，并不再伸缩后，其竖直方向上的加速度值会大于9.3，并稳定于预设加速度范围内。
因此，可以通过判断动态加速度值的趋势来确认其是否经过校正后位于硬质地面上，如果其趋于并稳定于预设加速度值范围，则认为其校正成功，当前体重检测装置位于硬质地面上，可以测量用户的称量信息。称量信息包括：体重信息。
本实施例中，根据动态加速度值的趋势来判断是否校正成功，只有在校正成功时，才测量用户的称量信息，使测量得到的称量信息的精确度更高。
优选地，所述步骤S100包括：步骤S110获取各支撑部在水平方向上的第一加速度值；步骤S100之后还包括：步骤S500当各支撑部对应的竖直方向上的加速度值都位于预设加速度范围内时，根据各所述支撑部对应的水平方向上的第一加速度值，判断体重检测装置是否处于水平状态；步骤S520当所述体重检测装置处于水平状态时，测量得到用户的称量信息。
具体的，通过测量静态重力加速度变化，转换成倾角变化，从而进行水平状态确认。可以安装有专门的水平传感器来测量体重检测装置的水平状态，也可以通过各支撑部上的加速度传感器测量得到的水平方向的第一加速度值，然后对数据进行处理，从而进行水平状态的判断。
对体重检测装置处于水平状态进行判断，以保证测量得到的称量信息比较准确。
优选地，所述步骤S500和所述步骤S520之间还包括：步骤S510当所述体重检测装置不处于水平状态时，调整相应的支撑部中的伸缩结构，使所述体重检测装置处于水平状态。
具体的，当体重检测装置位于硬质地面时，可能由于硬质地面的铺设问题使体重检测装置不处于水平状态，因此，需要使相应的伸缩结构伸出，抬高体重检测装置较低的位置，以使体重检测装置处于水平状态，保证精确的称量信息的测量。
在其他实施例中，除与上述相同的之外，步骤S410包括：步骤S411当各所述支撑部对应的竖直方向上的动态加速度值都趋于并稳定于所述预设加速度范围内时，获取各支撑部在水平方向上的第二加速度值；步骤S412根据各所述支撑部对应的水平方向上的第二加速度值，判断体重检测装置是否处于水平状态；步骤S413当所述体重检测装置不处于水平状态时，调整相应的支撑部中的伸缩结构，使所述体重检测装置处于水平状态；步骤S414当所述体重检测装置处于水平状态时，测量得到用户的称量信息。
具体的，当伸缩结构刺穿软质地面，抵到硬质地面时，已经完成了体重检测装置对放置的地面的材质的校正，进一步对其水平状态的确认，保证了后续称量信息的准确性。
在判断了伸缩结构抵到硬质地面时，再获取各加速度传感器当前的水平方向的第二加速度值，以保证获取的水平方向的第二加速度值可以准确地判断体重检测装置是否处于水平状态。
在称量时，既对体重检测装置放置的地面的材料进行校正、又对体重 检测装置的水平状态进行校正，保证了测量得到的用户的称量信息的精确性，提高了用户的使用体验。
优选地，步骤S400包括：步骤S420当至少一个所述支撑部对应的竖直方向上的动态加速度值趋于波动状态时，(则认为体重检测装置校准失败，仍位于软质地面)发出提示信息。
具体的，当体重检测装置无法成功刺穿软质地面(例如：泡沫)时，其伸出过程中的动态加速度值会来回跳动，且多次小于9.3(例如：以9.3作为参考基准)，动态加速度值不稳定，处于波动状态，且伸缩结构伸出过程中受到阻碍停止并维持当前的伸出状态时，因为还是处于软质地面，其最后的加速度值不会稳定于预设加速度范围内。
因此，可以通过动态加速度值的波动状态来确认是否对软质地面的问题校正成功，若不成功的，发出提示信息。这里的提示信息可以包括：语音提示、信息提示、灯光闪烁提示等。
例如：体重检测装置语音播报“处于软质地面，可能导致测量结果不准确，请移动体重检测装置(体脂秤)”；体重检测装置也可以将此提示信息发送给后台服务器，让后台服务器转发到用户的手机上(后台服务器分别与体重检测装置和手机通信连接)，让用户了解体重检测装置的当前情况；也可闪烁红光提示用户移动体重检测装置等。
当体重检测装置因外界因素无法保证称量信息的准确性时，提示信息的发出可以让用户及时了解当前的问题，提高用户的使用体验。

步骤S410当各所述支撑部对应的竖直方向上的动态加速度值都趋于并稳定于所述预设加速度范围内时，测量得到用户的称量信息；步骤S410包括：步骤S411当各所述支撑部对应的竖直方向上的动态加速度值都趋于并稳定于所述预设加速度范围内时，获取各支撑部在水平方向上的第二加速度值；步骤S412根据各所述支撑部对应的水平方向上的第二加速度值，判断体重检测装置是否处于水平状态；步骤S413当所述体重检测装置不处于水平状态时，调整相应的支撑部中的伸缩结构，使所述体重检测装置处于水平状态；步骤S414当所述体重检测装置处于水平状态时，测量得到用户的称量信息；
步骤S420当至少一个所述支撑部对应的竖直方向上的动态加速度值趋于波动状态时，发出提示信息；
步骤S500当各支撑部对应的竖直方向上的加速度值都位于预设加速度范围内时，根据各所述支撑部对应的水平方向上的第一加速度值，判断体重检测装置是否处于水平状态；步骤S510当所述体重检测装置不处于水平状态时，调整相应的支撑部中的伸缩结构，使所述体重检测装置处于水平状态；步骤S520当所述体重检测装置处于水平状态时，测量得到用户的称量信息。
具体的，本实施例中当用户使用体重检测装置时会对其当前放置的地面状态、水平状态进行校正，以保证用户测量得到的称量信息的准确性；当校正失败时，也会发出提示信息，以提醒用户，提高用户的使用体验。
在本发明的另一个实施例中，如图3、图5所示，一种体重检测装置，包括：体重检测装置本体1；多个支撑部2，分别设置于所述体重检测装置本体1的底部；每个支撑部2上还设置有一伸缩结构3，其可沿远离于所述体重检测装置本体的底部方向伸出，可沿靠近于所述体重检测装置本 体的底部方向缩进；当伸缩结构3未伸出时，伸缩结构的表面不高于支撑部的表面；所述伸缩结构具有圆滑过渡的尖端。
体重检测装置还包括：
控制模块10；加速度获取模块20，与所述控制模块10电连接，当接收到第一操作时，在所述控制模块的控制下，所述加速度获取模块用于获取各支撑部在竖直方向上的加速度值；以及，在所述控制模块的控制下，所述加速度获取模块用于获取各所述支撑部在所述伸缩结构伸出过程中竖直方向上的动态加速度值；
所述控制模块10，还用于当各支撑部对应的竖直方向上的加速度值不都位于预设加速度范围内时，所述控制模块控制各所述支撑部中的伸缩结构伸出；以及，所述控制模块根据各所述支撑部对应的竖直方向上的动态加速度值，执行相应的操作。
具体的，第一操作可以理解为使用体重检测装置的操作，例如：用户站在体重检测装置上想进行称量，或者，通过手机向体重检测装置发送了使用请求等操作，并站在体重检测装置上时。
当各支撑部对应的竖直方向上的加速度值都位于预设加速度范围内时，测量得到用户的称量信息。加速度获取模块可以由加速度传感器来实现。
软质地面包括：放置了地毯、泡沫塑料等软性材料的地面；因体重检测装置不直接与硬质地面接触，其实质是放置在软质地面(例如：铺着地毯的地板)上，因此，测量结果会有一定的误差。硬质地面包括：地板、水泥地、瓷砖等硬质材料的地面。
每个支撑部都会有一个相应的加速度传感器，当用户站在体重检测装置上时，通过加速度传感器来获取各支撑部对应的竖直方向上的加速度值。
当支撑部位于软质地面时，用户站在体重检测装置上，当体重检测装置受到用户的压力时，软质地面会对体重检测装置一个反弹的力，从而使支撑部获取的加速度值与体重检测装置在硬质地面上获取的加速度值有 变化。

碰到硬质地面时的动态加速度值和碰到软质地面时的动态加速度值是不一样的，因此，可以通过此来判断是否校正成功，从而执行后续相应的操作。
本实施例中，当用户使用体重检测装置时，会先判断体重检测装置是否位于软质地面，若是的话，会伸出伸缩结构执行校正，在判断是否校正成功后，再执行相应的操作，保证了用户的称量信息是体重检测装置经过校正后测量得到的，称量信息更准确，提高了用户的使用体验。
