Description

一种防碰撞的电动升降桌控制器
技术领域
本实用新型涉及电动升降桌领域，具体是一种防碰撞的电动升降桌控制器。
背景技术
伏案工作者常常久坐不动，很容易对脊椎颈椎等身体部位造成伤害；能调节高度的电动升降桌可帮助人们坐久时选择站立工作，既不耽误工作，也不影响健康。因而电动升降桌受到越来越多人的关注，特别是得到办公室人员的喜爱。
电动升降桌带给人们方便和健康的同时，也存在一些潜在的危害。电动升降桌运行过程中可能会无意碰撞到其他物体或者人体，造成对物体的损伤或对人体的伤害。
为了解决所述的潜在危害，通常在控制器中设计防碰撞保护功能。当电动升降桌运行过程中受到碰撞，电机电流就会发生变化，控制盒侦测到电流变化，立即停止升降桌的动作或停止后再向反方向退行一段距离。
上述防碰撞保护方式，是靠侦测电流的变化来实现的。若保护设置的太灵敏，即电流变化很小就要起保护，就会造成升降桌运行时，即使没有受到碰撞，也会因电机本身的电流波动而误停止；若保护设置的太迟钝，即电流变化较大才起保护作用，就会造成受到碰撞并产生很大挤压力后才保护，但这时可能已经造成了物体的损坏和人体的伤害。特别是升降桌在负重下降运行时，即使受到较大碰撞阻力，电流变化也不明显，这时该方案的缺陷就更突出。
实用新型内容
为了现有技术中存在的上述技术问题，本实用新型提供了一种防碰撞的电动升降桌控制器，包括MCU，电机驱动电路，电机电流取样电路，电流放大电路，HALL脉冲产生器和HALL滤波器，MCU控制电机驱动电路，HALL脉冲产生器传来的信号，通过HALL滤波器送到MCU，电机电流经电机电流取样电路取样后，经电流放大电路送入MCU，用于侦测电流变化，还包括震动开关，震动开关设置在控制器外部与MCU连接，或者设置在控制器内部。
本实用新型采用电流侦测加震动侦测相结合的方式，提高了防碰撞保护的灵敏度和可靠性。
附图说明
图1是本实用新型的防碰撞的电动升降桌控制器的框架图；
图2是MCU及震动开关的电路图；
图3是电机驱动电路图；
图4是电流放大电路图；
图5是HALL滤波器电路图。
具体实施方式
下面结合附图对本实用新型作进一步说明。
如图1-5所示，本实用新型的防碰撞的电动升降桌控制器，包括MCU，电机驱动电路，电机电流取样电路，电流放大电路，HALL脉冲产生器和HALL滤波器，MCU控制电机驱动电路，通过PWM方式调节电机速度，HALL脉冲产生器传来的信号，通过HALL滤波器滤除马达的杂信，送到MCU，HALL信号反映电机转动的圈数，从而MCU能得知电机速度和位置，电机电流经电机电流取样电路取样后经电流放大电路送入MCU，用于侦测电流变化。还包括震动开关，震动开关设置在控制器外部与MCU连接，或者设置在控制器内部。
电动升降桌正常运行时，运行平稳，不会震动，不会触发保护；当升降桌运行过程中受到碰撞，就会产生震动，震动传递到震动开关，震动开关触发MCU进行保护。
电动升降桌通常由两个或三个电动升降柱组成，这几个升降柱必须保持同步运行，才能保证桌面水平运行。所以在运行过程中，每个电动升降柱必须及时调整速度来达到同步运行，一般都采用PWM的方式进行速度的改变，相当于改变电机的供电电压来改变速度。通常的调整方式是这样的：当A落后于B，就加大A的电压（实际上是增加PWM的DutyCycle，下同），减小B的电压，A就快于B；当A超过B，这时又要减小A的电压，增加B的电压；如此周而复始不断调节AB的电压来实现同步运行。因为每个电动升降柱的电机电压在不断变化，其电流自然就会不断变化。在这种情况下，为了不出现误保护，只能增大起保护时电流变化的阈值（超过电流波动值），从而造成保护更加迟钝，即需要更大的碰撞力才能保护。
本申请在同步处理上采用PID自动控制技术，通过该控制技术，每个升降柱能自动按设定的速度和设定的目标位置保持匀速运行，将两个或三个升降柱设定成相同的速度和相同的目标位置，就能实现同步运行。运行中只要升降柱的负重不发生变化，电机的电压（实际上是PWM的Duty Cycle）就不会再进行调整，也就是不会反复变化，相应地，电流就不会反复变化。这种同步控制方式，电流平稳，不会增加额外的电流波动，因而能提高电流侦测的灵敏度。
