Description

一种体重检测装置的预热控制方法及体重检测装置 技术领域
本发明属于体重检测技术领域，特别涉及体重检测装置的预热控制方法及体重检测装置。
背景技术
随着人们生活水平的不断提高，健康问题也越来越得到重视，促进人体测量科学的发展。人们通常可以利用体重秤获取体重信息，利用体脂秤测量人体脂肪百分比、人体水分百分比、人体肌肉百分比、骨骼重量等人体成分。
人体脂肪是人体的重要组成部分，在人体内有重要的功能和作用，例如：提供能量、保护内脏、维持体温、协助水溶性维生素的吸收等。健康的身体，在于体内脂肪的平衡，脂肪过量积聚会对身体产生危害，导致各种疾病，例如：糖尿病、心脑血管疾病等。
其中，体脂秤，是利用秤体表面的电极片与用户的双脚接触后，通过一定的安全电流，测量人体电阻。由于肌肉内含有较多血液等水份，是可以导电；而脂肪不导电；从流过的电流可知肌肉的重量。由此可判断出，在体重的比例中，人体脂肪的含量。
目前，市场上有很多体重秤都没有预热功能，尤其是体脂秤，在用户利用体脂秤测量体脂时，为了测得准确的数据，其脚部与秤表面不能绝缘，需要光脚踩在体脂秤的表面。当体脂秤的表面温度过低时，会对用户的使用体验造成影响，使得用户在外界温度较低的情况下，减少体脂秤的使用次数，进而失去对用户身体健康的监控。

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。
如图1所示，根据本发明的一个实施例，一种体重检测装置的预热控制方法，包括以下步骤：S10、按照第一预设间隔时间(例如2S、5S等)在各个发射方向上发射出的发射微波，在所述发射方向上遇到被测对象后，反射回来的部分发射微波作为反射微波；所述发射微波的波长在1毫米～1米。
S20、根据反射回来的反射微波、以及所述反射微波的接收时间，识别出所述发射方向上的被测对象是否为新增被测对象；当所述被测对象为新增被测对象时，则执行步骤S30；否则，执行步骤S10。
S30、根据反射回来的反射微波、以及所述反射微波的接收时间，识别出所述新增被测对象是否处于运动状态；当所述新增被测对象处于运动状态时，则执行步骤S50；否则，执行步骤S40。
S40、当所述新增被测对象处于静止状态时，则所述新增被测对象所处发射方向上的发射微波按照第二预设间隔时间(例如10S、20S等)发射出发射微波后；执行步骤S30；所述第二预设间隔时间大于所述第一预设间隔时间。
S50、根据当前反射回来的当前反射微波、以及所述当前反射微波的当前接收时间，计算出所述新增被测对象当前至所述发射微波所处发射地的当前距离。
S60、所述体重检测装置上的加热器根据所述当前距离，对所述体重检测装置上的受热区进行预热控制。
具体的，体重检测装置包括体脂秤、体重秤等；将体脂秤或体重秤放置在房间内的一位置处，在距离体脂秤或体重秤0.6m内没有障碍物，体脂秤或体重秤上的加热器处于关闭状态。安装在体脂秤或体重秤上的微波收发器每隔2S在各个方向上(体 脂秤或体重秤的周侧方向)发射波长为1m的发射微波。
体脂秤或体重秤放置在房间的一位置处时，预先向体脂秤或体重秤四周周侧发射波长为1m的预设发射微波，利用接收到的预设反射微波，以及接收预设反射微波的预设接收时间，探测出体脂秤或体重秤所处环境，从而了解体脂秤或体脂秤的周围环境，作为识别是否出现新增被测对象的参考标准。
由于每种物体对微波的吸收能力、反射能力、穿透能力不同，可以识别出被测对象的种类。根据预设接收时间、微波的传输速度，预设发射微波的预设发射时间，计算出被测对象至体脂秤或体重秤的距离。结合被测对象的种类、距离、发射方向，得到体脂秤或体重秤的周围环境。
当微波检测范围内(体脂秤或体重秤周侧距离体脂秤或体重秤1m的范围)出现新增被测对象，其当前反射微波、当前接收时间，相对于预设反射微波、预设接收时间来说，发生了改变。
当微波检测范围内出现新增被测对象，进一步识别出新增被测对象是静态的，还是动态的。若新增被测对象是动态的，根据新增被测对象的当前距离，体脂秤或体重秤上加热器对受热区进行预热，其预热电流根据用户站在体重检测装置时，所花费的时间，以及目标加热温度确定。
微波是指频率为300MHz～300GHz的电磁波，即波长在1毫米～1米之间的电磁波，是分米波、厘米波、毫米波的统称。微波作为一种电磁波具有波粒二象性。微波的基本性质通常呈现为穿透、反射、吸收三个特性。对于玻璃、塑料和瓷器，微波几乎是穿越而不被吸收。对于水和食物等就会吸收部分微波而使自身发热。而对金属类东西，则会反射部分微波。
如图2、图4、图7所示，根据本发明的又一个实施例，一种体重检测装置的预热控制方法，包括以下步骤：S10、按照第一预设间隔时间(例如2S、5S等)在各个发射方向上发射出的发射微波，在所述发射方向上遇到被测对象后，反射回来的部分发射微波作为反射微波；所述发射微波的波长在1毫米～1米。

S22、当所述反射微波、接收时间与预设反射微波、预设接收时间不一致时，识别出所述发射方向上的被测对象是新增被测对象；
S23、当所述反射微波、接收时间与预设反射微波、预设接收时间一致时，识别出所述发射方向上的被测对象不是新增被测对象。当所述被测对象为新增被测对象时，则执行步骤S30；否则，执行步骤S10。
S30、根据反射回来的反射微波、以及所述反射微波的接收时间，识别出所述新增被测对象是否处于运动状态；当所述新增被测对象处于运动状态时，则执行步骤S50；否则，执行步骤S40。
S40、当所述新增被测对象处于静止状态时，则所述新增被测对象所处发射方向上的发射微波按照第二预设间隔时间发射出发射微波后，执行步骤S30；所述第二预设间隔时间大于所述第一预设间隔时间。
S50、根据当前反射回来的当前反射微波、以及所述当前反射微波的当前接收时间，计算出所述新增被测对象当前至所述发射微波所处发射地的当前距离。

S62、当所述当前距离小于所述预设距离时，则所述体重检测装置上的加热器对所述体重检测装置上的受热区进行预热；
S63、当所述当前距离大于、等于所述预设距离时，则所述体重检测装置上的加热器放弃对所述体重检测装置上的受热区进行预热。
S70、统计每个发射方向上出现新增被测对象的对象新增频率、以及所述新增被测对象发生运动的运动频率；
S80、逐一判断每个发射方向上的对象新增频率是否大于预设对象新增频率，以及所述运动频率是否小于预设运动频率；当一个发射方向上的对象新增频率小于预设对象新增频率时，则执行步骤S81；当一个发射方向上的对象新增频率大于预设对象新增频率、且所述运动频率小于预设运动频率时，则执行步骤S82。
S81、提示用户关闭或自动关闭在该发射方向上发射出发射微波；
S82、该发射方向上的发射微波按照第二预设间隔时间(例如12S、25S等)发射发射微波后，执行步骤S20；所述第二预设间隔时间大于所述第一预设间隔时间。
具体的，根据统计周期(例如一周、两周)，统计一下各个发射方向上出现新增被测对象的对象新增频率；以及新增被测对象发生运动的运动频率。当一个发射方向上的对象新增频率为零，提示用户关闭或自动关闭该发射方向上发射出发射微波的功能。当一个发射方向上的新增频率大于零，运动频率比较少，则延长该发射方向上发射微波的发射间隔时间，即将第一预设间隔时间修改为第二预设间隔时间。当一个发射方向上的新增频率大于零，运动频率比较多，则维持该发射方向上发射微波的发射间隔时间(第一预设间隔时间)。

S50、根据当前反射回来的当前反射微波、以及所述当前反射微波的当前接收时间，计算出所述新增被测对象当前至所述发射微波所处发射地的当前距离。
S60、所述体重检测装置上的加热器根据所述当前距离，对所述体重检测装置上的受热区进行预热控制。
优选的，所述步骤S60进一步包括：S61、判断所述当前距离是否小于所述预设距离；所述预设距离可以设置为0.6m、0.4m等。

根据本发明的又一个实施例，一种体重检测装置的预热控制方法，包括以下步骤：设备开启工作状态，开始向某一个方向发出一定波长的微波(可在一定程度上保证直线传输)；在发射的同时开始接收和分析反射回来的微波信号。
由于发射到接收到反射波有一定的时延和能损，且不同物质对同一种微波的反射和吸收能力不同，故通过实验便可获取到不同距离及物质对本发明所用微波的吸收和反射数据。将实验获取到的数据作为原始数据，以便和工作时的环境信息做对比，从而建模，分析出空间内的环境信息。
设备在使用过程中，会将无运动趋势的物体作为“静态物质”对待，如果设备发现某一方向没有出现过运动物体时，会选择自动或提醒用户关闭此方向的发射及接收设备。当此方向很少出现运动设备时，会减少此方向上发射及接收设备的开启时长，以降低功耗。
当空间内出现运动体时，反射回来的微波会存在反射时延的变化，从而分析出该物体的运动趋势及运动信息；当空间内出现生命体时，可通过查询数据库内的数据，从而得到反射 源的相关信息。
将获取的数据进行分析、建模，然后进行下一步处理。
当符合人类学的运动体向电子秤运动，且运动距离达到之前设定的某一个阈值时，设备启动预热模式；当用户走到电子秤时，刚好可以使用电子秤。
设备可在用户使用频率低的时段主动降低发射频率；设备可控制侧边上的不同发射和接受装置，当发现某一方向不可能有人出现时(如墙体)，可自动关闭某一个发射与接收设备。。
具体的，首次使用时，设备向某个方向发射出一定波长的微波，同时接收反射回来的微波，对周围环境进行分析建波，得到原始数据。当有生命体在电子秤所在空间；系统发出一定波长的微波，并接收反射回来的微波。通过与之前或得到的数据进行比对，发现空间内的新增、运动的物体，判断出其运动趋势。持续进行发出微波，当发现有符合人类信息的运动物体向电子秤走来时，系统启动预热模式；设备侧边的信号发射与接受源分离，互不干扰，从而实现同时接受和发射信号。
应当说明的是，上述实施例均可根据需要自由组合。以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
