随着社会的不断发展，人们的生活水平不断提高，人们对于自身的健康情况越来越重视。体重是反映日常饮食摄入量是否达标的重要指标，当一个人的体重过低时，代表这个人日常饮食摄入量过低，其能量摄入未能满足自身的能量消耗；当一个人的体重过高时，代表这个人日常饮食摄入量过高，其能量摄入超出自身的能量消耗。并且，当一个人的体重在短时间内发生明显变化时，很有可能是这个人患有疾病的表现，因此，体重是衡量人们健康状况的重要参数。
目前，市场上的体重测量仪种类繁多，通常包括称重平台，在称重平台设置称重传感器，检测结果通过显示模块进行显示。工作时，在检测到称重平台承重后，开始启动仪器并进行测量。
这种方式虽然能够及时快速的启动和称重，但是显示模块在显示称重结果时，需要正对数字显示的方向观看，而若使用者站到了错误的方向，测量仪照常启动，虽然也能够积进行测量，则可能对称重结果的观察不够方便，现有产品还有改进的空间。

将显示模块4隐藏在称重平台1内，并且在显示模块4未进行显示时，称重平台1呈一个整体，不会突兀的表现为一个体重秤，易于搭配环境，具有隐层的效果。
在需要测量体重时，使用人员向体重测量装置靠近，若其靠近和站在称重平台1的方向为正确方向，即由图4的下方靠近和站在称重平台1，则人 体检测模块52获取到使用人员的信息之后发送给处理模块6，处理模块6判断使用人员所站立方向正确后，启动体重测量装置的称重功能。
接着，称重传感器51获取四个边角受到的重力大小，之后传送至处理模块6，处理模块6通过预置的算法对重力大小进行分析，综合计算处当前所受到的重力大小，并且将称重结果发送至驱动电路41，驱动电路41将称重结果转化为显示信息，经由显示模块4进行显示，发光LED点亮后透过盲孔3的透光内壁，向称重平台1的顶侧发出，进而被人体观察得到。
而在显示模块4显示达标准时长时，光致变色罩81变为透明，光线照射至荧光块8，荧光块8开始吸收光能，而在显示模块4的显示时长达到预设时长时，显示模块4停止光照，而此时荧光块8开始发光，继续保持一段时间的显示效果，更为节能。
以上所述仅是本实用新型的优选实施方式，本实用新型的保护范围并不仅局限于上述实施例，凡属于本实用新型思路下的技术方案均属于本实用新型的保护范围。应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型原理前提下的若干改进和润饰，这些改进和润饰也应视为本实用新型的保护范围。
