Lifting and dropping of the mechanical arm are realized through ball screw driven by gear motor with belt brake , meanwhile , double security protection is applied , namely , at normal operation limit , the proximity switch is adopted and at upper or lower limit , the stroke switch is available 上下动作采用带刹车减速电机带动滚珠丝杆实现,并采用二级安全保护,即正常工作限位采用接近开关,上下限限位采用行程开关。
Cg - 1 magnets sensors also known as pm proximity switch sensor in the elevator shafts for flat layer control . because of its speed is faster , high reliability and energy - saving advantages , it can be widely used in various movements to control spacing and other equipment for automatic control system for sensing element role Cg - 1型永磁感应器cg - 1型永磁感应器亦称永磁接近开关在电梯中作井道传感元件使用,即电梯平层控
For the safety , protecting sets were used to avoid the system from hitting with other wheel sets . optoelectronic switches were used to protect the movement units and sensors . self - detecti ng program could detect the status of sensors and wheel set 系统安全性设计上采用挡轮装置防止前后轮对碰撞在检轮对,系统可靠性设计上硬件采取光电开关和接近开关装置,防止运动超限或传感器发生碰撞,软件上采用自检程序检测各传感器及板卡工作状态,具有自动诊断功能。
With the mathematic model of tracking beam current by velocity , real - time tracking can be obtained ; with current simulation controlling transducer and subsection linearity , precision of velocity ( error in ? 1 % ) is triumphantly can be controlled ; with inspection of the pulse numbers of switches , the position of all vehicles are checked to eliminate the error of calculating distance between all ones 通过建立速度跟踪束流的数学模型,较好地解决了速度跟踪束流的实时性问题;通过采取用电流模拟量控制变频器和分段线性处理的办法,成功地解决了速度精度问题(误差在士1 %内) ;通过检测接近开关触发的脉冲数,适时校核所有小车位置,消除各车之间距离计算误差,从而很好地解决了距离累计计算误差。
