Description

工作台面组件及控制方法 技术领域
本发明涉及一种工作台面组件及控制方法，尤其涉及一种可手势控制的垂直调节的工作台面组件及其控制方法。
背景技术
长时间坐在固定式办公桌前，不仅可能导致视力下降，而且会带来颈椎病、腰椎病等办公职业病，所以逐渐发展出了坐站交替式的办公以及办公升降桌，并越来越成为一种流行的健康办公方式，其理念也得到逐渐广泛的认可和应用。
目前的办公升降桌一般多采用手摇杆的人力方式或者电动马达驱动方式。手摇方式的升降效率普遍偏低，调整同样高度，手摇往往是电动的数倍甚至十倍以上。电机驱动虽然是目前的主流，但其操作不够自然。
现有技术如专利文献CN105795709A中公开了一种智能升降桌及其智能升降方法，该升降桌包括微处理器、停止升降信号感应传感器、电路控制与驱动电路等，停止升降信号感应传感器为反射式光电传感器，微处理器通过电路控制与驱动电路控制桌面升降驱动单元动作，实现可升降桌面的升降，同时微处理器通过停止升降信号感应传感器检测停止升降信号，若检测不到则继续升降，若检测到则停止升降。其中，升降命令是指通过触摸屏接收调节桌面高度的升降命令，或者通过麦克风接收调节桌面高度的语音升降命令，或者通过按键接收调节桌面高度的升降命令。使用者需保持自然站立的姿势，上臂下垂，保持前臂与上臂垂直，并且将前臂置于反射式光电传感器的升降路径上，当受前臂遮挡，反射式光电传感器发出的光线有一部分被反射回来并被接收到，停止升降。
上述方案中，开始升降和停止升降的信号分别通过两个物理模块实现，操作比较僵硬，比单纯的按键式操作反而增加了复杂度。停止升降信号的操作逻辑非常模糊，操作性不强，例如，当传感器收到非前臂的其他物体遮挡，也会产生错误信号而引入误操作。
有鉴于此，如何设计一种新的工作台面组件及控制方法，以消除现有技术中的上述缺陷和不足，是业内相关技术人员亟待解决的一项课题。
发明内容
为了克服上述现有技术中存在的问题，本发明提供了一种操作便利、可实施性强的可手势控制的垂直调节的工作台面组件及其控制方法。
本发明第一方面，公开了一种手势控制垂直调节的工作台面组件，包括：
高度可调的支撑柱，所述支撑柱用于垂直调节工作台面相对于地面的高度；
联接到所述支撑柱的工作台面，所述工作台面上设置有自控模块，所述自控模块包括手势传感器、控制单元和显示单元，其中，
所述手势传感器用于实时检测作用在感应区内的手势特征，所述感应区包括距离所述工作台面的上表面或下表面高度为H的区域；
所述控制单元，用于实时访问读取所述手势传感器检测到的手势特征，并控制所述支撑柱的垂直调节；
所述显示单元用于显示所述工作台面相对于地面的实时高度。
在另一优选例中，所述手势传感器包括测距传感器、光电传感器、人体接近传感器或超声传感器。
在另一优选例中，所述手势特征包括上升手势、下降手势或水平手势。
在另一优选例中，所述手势传感器位于所述工作台面的上表面。
在另一优选例中，所述手势传感器位于所述工作台面的上表面和下表面。
在另一优选例中，所述高度H的范围为7-8cm至15-20cm。
本发明第二方面，提供了一种本发明第一方面所述的工作台面组件的手势控制方法，包括步骤：
(1)在所述感应区内维持T1时间的第一手势特征，所述手势传感器实时检测所述第一手势特征的起点和所述第一手势特征距离工作台面的第一高度h1；
(2)所述控制单元实时读取所述第一手势特征和所述第一高度h1，启动支撑柱的垂直调节；
(3)提供第二手势特征，所述手势传感器实时检测所述第二手势特征及其起点，所述控制单元实时读取所述第二手势特征并控制支撑柱的垂直调节，直至所述工作台面与所述第二手势特征终点的距离达到h1。
在另一优选例中，所述第一手势特征为水平手势，并且所述第二手势特征为上升手势或下降手势。
本发明第三方面，提供了一种本发明第一方面所述的工作台面组件的手势控 制方法，包括步骤：
(a)在所述感应区内维持T1时间的水平手势，所述手势传感器实时检测水平手势，所述控制单元实时读取水平手势，启动支撑柱的垂直调节；
(b)提供第三手势特征，所述手势传感器实时检测所述第三手势特征及其起点，所述控制单元实时读取所述第三手势特征并控制支撑柱的垂直调节，直至所述第三手势特征水平抽离感应区或超出感应区的范围。
在另一优选例中，所述第三手势特征为上升手势或下降手势。
与现有技术相比较，本发明所提供的技术方案具有以下优点：
1.本发明中的利用手势控制可垂直调节的工作台面组件，采用手势传感器(包括但不限于测距传感器、红外传感器等)测量用户的手与工作台面之间的距离，当手势保持在感应区范围内时，发出开始升降以及升降的指令，当手势离开感应区范围时，发出升降停止的指令。
2.本发明中，工作台面的上方和/或下方存在一定范围作为感应区，只对限定高度范围内的用户手势进行响应，并且用户的手势需稳定在一定高度一段时间后再开启调节，而结束调节只需要把手势离开感应区即可。
3.本发明中，工作台面的上表面或下表面均可设置传感器，传感器的分开设置更加符合用户的行为习惯，手势上升控制工作台面上升，手势下降控制工作台面下降；同时，分开设置的传感器也可以避免因手势不稳造成的升降错误。
4.本发明中工作台面的升降信号感应和停止信号感应均采用同一组传感器，用户操作便利，可实施性强，不额外增加复杂度。
5.双传感器的设定极大地减少了误干扰情况的发生，用户需要使用平时较少用到的双手手势进行控制；同时，传感器的设置位置尽量远离正常书写和办公可能的手部位置，结合双手手势控制，极大地减少了错误触发。

术语解释
控制单元：负责协调整个工作台面组件各子模块的协同工作，并且实时读取手势传感器检测到的手势特征的变量值。
手势传感器：本发明中的手势传感器实时检测用户在感应区内的手势特征(包括但不限于水平放置、上升/上抬、下降/下压)，传送至控制单元，以引发支撑柱的垂直调节。本发明中，优选的手势传感器包括测距传感器、红外传感器、人体接近传感器或超声传感器等。手势传感器的数量、安装位置可根据用户需要进行设置，本发明不做特别限定。
感应区：指手势传感器可以感应到用户的手势特征的区域，优选地，本发明中，感应区为距离工作台面的上表面和/或下表面为7-8cm至15-20cm范围的区域。
实施例一
如图1所示，显示了本发明第一种实施方式中的工作台面上表面和下表面的手势传感器的位置平面示意图，其中，测距传感器分别设置在工作台面的上表面和下表面。
本发明的工作台面组件包括底座、立柱、支撑柱等(图示未标出)与自控模块。
本实施例中，采用的手势传感器为测距传感器，如图2所示，在工作台面的上表面和下表面分别设置两个测距传感器，呈交替排布，其中，工作台面下表面的传感器用于控制工作台面的上升，上表面的传感器用于控制工作台面的下降。
测距传感器104在靠近用户一侧的桌板上设置，以用户位置为中线，左右对称，更加靠近左右两侧桌沿。工作台面下表面的测距传感器的分布位置可不与上表面一致。
预设的感应区高度指距离工作台面的上表面或下表面为H的区域，H的范围为7-8cm至15-20cm，本领域技术人员可根据工作组件本体的高度、用户情况等其他条件进行设定，本发明不做特别限制。工作台面的上方和下方可设置不同的感应区高度，更加符合人体工程学，例如下方的感应区高度更小一些。因此，介于感应区范围内的手势才会触发升降指令。
用户在感应区内保持水平手势T 1时间(优选地为3-5s)后，测距传感器实时读取该水平手势及其距离工作台面的距离，控制单元输出升降指令，启动支撑柱 的垂直调节，工作台面开始随用户手势的上升或下降而上升或下降，直至手势离开感应区范围，控制单元输出停止升降指令。
优选地，本实施例中的工作台面组件还包括提示单元，提示单元可包括显示单元和声音播放单元，显示单元显示工作台面当前距离地面的高度，声音播放单元用于提示用户工作台面升降的开启和停止。
如图3所示，显示了本发明第一种实施方式中的控制流程：
(1)用户把双手放置在工作台面上表面的测距传感器的感应区范围内，保持高度维持时间3-5s，声音提示单元提示开始调节；
(2)工作台面开始随用户手势上升或下降进行垂直调节，显示单元显示工作台面当前距离地面的高度，该过程中用户需维持双手在感应区内，只要双手离工作台面上表面的距离不超过感应区范围的上限值，工作台面会持续上升或下降；
(3)用户可通过观察显示单元显示的实时高度，只要达到用户的目标舒适高度，仅需将双手抽离平面感应区域或者抬高/降低超出感应区高度范围，升降停止。
实施例二
本实施例中，工作台面组件仅在工作台面的上表面分布有两个测距传感器，同时控制工作台面的上升和下降。同实施例一，测距传感器同样在靠近用户一侧的桌板上设置，以用户位置为中线，左右对称。
用户双手在感应区内维持高度T 1(优选地为3-5s)后，控制单元输出升降指令，且记录当前双手与工作台面之间的初始距离h 2，作为后续工作台面调节高度的依据。
起始时用户双手距离工作台面的距离的当前值为h 1，工作台面依据当前的h 1，使其达到h 2。例如，上升手势时，h 1变大，此时h 1>h 2，为了使得h 1缩小至h 2，工作台面会上升，直至上升至h 1＝h 2；同理，下降手势时，h 1变小，此时h 1<h 2，为了使得h 1变大至h 2，工作台面会下降，直至下降至h 1＝h 2。
如图4所示，显示了本发明第二种实施方式中的控制流程：
(1)用户将双手放置在工作台面上表面测距传感器的感应区范围内，保持高度维持时间3-5s，声音提示单元提示开始调节；
(2)手势向上移动到目标高度附近，工作台面上升，使得手与工作台面之间的距离h 1逐步降低直至达到h 2。
优选地，工作台面的垂直调节启动时，双手均处于感应区。
优选地，初始距离h 2可采用单手设定，垂直调节启动后，仅以单侧手距离工作台面的高度计h 1，为了防止单侧手位置不稳定而出现的忽而上升忽而下降的情况，可在当前调节方向的反方向设置一最低高度h 3，当高度调节的变动不超出最低高度h 3时，可认为已经达到用户的目标高度，从而停止垂直调节。
优选地，上述控制流程还包括步骤(3)：当h 1达到h 2后，如果再次抬手，则工作台面继续升高，此时如果下压手，h 1与h 2的高度差不超过h 3，则认为上升结束；如果h 1与h 2的高度差超过h 3，则工作台面下降以调整。
如无特别说明，本文中出现的类似于“第一”、“第二”的限定语并非是指对时间顺序、数量、或者重要性的限定，而仅仅是为了将本技术方案中的一个技术特征与另一个技术特征相区分。同样地，本文中出现的类似于“一”的限定语并非是指对数量的限定，而是描述在前文中未曾出现的技术特征。同样地，本文中在数词前出现的类似于“大约”、“近似地”的修饰语通常包含本数，并且其具体的含义应当结合上下文意理解。同样地，除非是有特定的数量量词修饰的名词，否则在本文中应当视作即包含单数形式又包含复数形式，在该技术方案中即可以包括单数个该技术特征，也可以包括复数个该技术特征。
本说明书中所述的只是本发明的较佳具体实施例，以上实施例仅用以说明本发明的技术方案而非对本发明的限制。凡本领域技术人员依本发明的构思通过逻辑分析、推理或者有限的实验可以得到的技术方案，皆应在本发明的范围之内。
