背景技术
中国己于1999年10月提前进入人口老龄化国家的行列，并以年均3.32％的速度持续增长。根据统计资料约79.1％的老人至少有一种或一种以上的慢性病，高龄老年人自我照料能力减弱，对家庭、社区、政府依赖程度加大。家庭式护理对老年人的关照也日趋减弱，客观上增加了老年人、残疾人护理的困难。
医疗护理器械高新技术含量越来越多，对新工艺、新设计、新材料的要求越来越高。国外多功能的护理器械造价高昂，国内护理病床的发展远远不能满足实际的需要，功能比较单一、自动化程度不高等原因是现有一些多功能护理病床得不到大众化推广的原因之一。
护理床是行动不方便的病人在住院或居家护理时使用的病床，更舒适和便于医护人员进行康复的电动病床，不仅具有护理作用，还能促进病人病情的缓和和康复。
现在医院使用的病床多数是手摇病床，病人如果需要调整病床高度，还需要他人的帮助，病人很受约束，同时少部分可通过电控制的电动病床，其在使用的过程中，功能简单，在护理应用的过程中，容易出现使用不便的问题，从而影响护理使用的效果。
为此，本发明团队提出了一系列解决技术方案，以期提高电动病床的智能化程度，诸如CN106137612A、CN106137614A、CN106074043A、CN105997396A、CN105997397A、CN106137613A、CN106176085A、CN106176093A、CN106074040A、CN106137605A、CN105997398A、CN106074035A、CN105997391A、CN106137604A、CN106074046A、 CN106074045A、CN106074041A、CN106137615A、CN106137621A、CN106074042A、CN106074049A、CN106074048A、CN106137619A、CN106137620A、CN106074047A、CN106020069A、CN106176094A、CN105997392A、CN106137618A、CN106074036A、CN106137617A、CN106137616A、CN106137606A、CN106074044A、CN106667684A。通过采用单核或者双核、单轮、双轮、四轮驱动实现对电动病床的智能化。这些内容通过参考结合于此文。

在本发明的一个实施例中，为了更加平稳，平缓在移动或者推动过程中频繁的刹车和启动造成的顿挫感，所述STM32系列芯片采用双核的控制方式实时控制。
该基于STM32医用电动病床，在使用时，将各部件组装完成后，当患者躺在床板5上，可通过遥控设备操控各设备的运转，当需要对床板5的高度进行升降调节时，通过STM32系列的芯片控制器，启动第一电推杆2伸缩，第一电推杆2在伸缩时，带动支撑顶框4和床板5高度的调节，同时当需要床板5的水平旋转时，启动第一电机9转动，由第一电机9转动带动床板5在支撑顶框4上旋转，对水平角度进行旋转，同时当需要对床板5两端腰部支板15和腿部支板13的翻转时，启动第二电机11或者第三电机12，第二电机11和第三电机12转动时，会启动对应的第二蜗杆32和第一蜗杆31转动，第一蜗杆31和第二蜗杆32转动时，分别通过蜗轮带动丝杠23的转动，使得丝杠23转动时，调节滑板24向第一电机9方向移动，滑板24移动时，通过第一斜推杆6和第二斜推杆7，带动第一翻杆19或者第二翻杆20向上翻转，进而将腰部支板15或者腿部支板13在固定支板14的一侧翻转，实现对腰部支板15或者腿部支板13的角度调节，满足躺靠的需求，并在腰部支板15翻转的过程中，还可以启动靠垫17下方第三电推杆的伸缩，调节靠板伸缩，使躺靠时更舒服，以及在腿部支板13水平时，可启动第二电推杆8伸展，由第二电推杆8伸展，将桌板16从腿部支板13内的顶出，可将桌板16顶出使用。
