摘要： A system for controlling operation of an elevator car door includes a torque command output device for outputting a torque command for controlling a car door driving motor on the basis of a difference between a speed command commanding the operating speed of the motor and the actual speed of operation of the motor, a door position detector for detecting the position of the car door in terms of the number of pulses in a pulse train produced by an encoder connected to the motor, and a memory for storing torque limit values as a function of the door position. The system also has a controller which reads the torque limit value corresponding to the car door position detected by the door position detector. The controller then compares the read torque limit value with a torque command output from the torque command output device and generates a reversing instruction to be given to the motor upon determining that the torque command is not smaller than the torque limit value. An obstruction of the door is sensed as a rise in the torque command so that the car door is reversed to ensure safety.

摘要： When an excitation of a servo motor is released due to an emergency stop, a power outage, or another operation performed on a positioning device, the positioning device uses air supplied from an air supply source to vary pressure of an air balance, which cancels a self-weight of a vertical axis driven by the servo motor, thereby moving the vertical axis.

摘要： An improved method of detecting the presence of an obstacle in the path of a motor-driven panel by computing the slope of a measured motor speed signal in a way that cancels the effect of periodic undulation of the speed signal, and comparing the computed slope to a slope threshold that is selected as a function of the average motor speed. A position sensor produces a series of pulses corresponding to panel movement, and a microprocessor-based controller stores an array of speed-related samples corresponding to the time periods between successively produced sensor pulses. The average speed is computed at two different points in the array, and the slope of the stored speed samples is determined according to a difference between the computed average speeds. Periodic variation in successive motor speed samples due to a periodic variation in the sensor pulse spacing has a repetition interval corresponding to a fixed number of samples, and the average speeds are computed based on speed samples that are separated by one-half of the repetition interval to substantially eliminate the effect of the periodic variation. The slope threshold for obstacle detection decreases with increasing average motor speed so that obstacle detection occurs when the obstacle exerts a given force on the panel, regardless of the panel speed.
摘要翻译： 通过以消除速度信号的周期波动的影响的方式计算测量的电动机速度信号的斜率，并将计算出的斜率与计算出的斜率进行比较，从而检测电动机面板路径中存在障碍物的改进方法 作为平均电动机速度的函数选择的斜率阈值。 位置传感器产生对应于面板移动的一系列脉冲，并且基于微处理器的控制器存储对应于连续产生的传感器脉冲之间的时间段的速度相关样本的阵列。 在阵列中的两个不同点计算平均速度，并且根据计算的平均速度之间的差来确定所存储的速度样本的斜率。 由于传感器脉冲间隔的周期性变化，连续的电动机速度样本的周期性变化具有对应于固定数量样本的重复间隔，并且基于以重复间隔的一半分开的速度采样计算平均速度 以基本上消除周期性变化的影响。 障碍物检测的斜率阈值随着电机平均速度的增加而减小，当障碍物在面板上施加一定的力时，无论面板速度如何，都会发生障碍物检测。

摘要： A gate operator with an extensible actuating arm adapted for light to moderate gate passing traffic. The operator comprises a small drive unit, such as an electric motor drive, and a rotatable drive shaft, such as a worm shaft driven through operation of the motor. An extensible shaft or so-called ball race shaft, cooperates with the rotatable shaft and extends inwardly or outwardly in response to rotation of the rotatable shaft. A microprocessor operated control circuit is used with or forms part of the operator, and measures a number of counts generated by magnetic elements rotatable with the worm shaft, and which are equivalent to distance units of measurement. In this way, the distance on the opening and closing movement is measured and stored in the microprocessor, so that on subsequent movements, the gate can open and close to precisely the open and closed positions without stopping short of or banging into such end positions. The motor mechanism of the operator is pulsed during the complete first opening movement and the complete first closing movement due to the fact that the operator does not know the exact position of the gate when the operator is first started. In this way, in the event of any bottoming out of the extensible and retractable arm, such as the ball race shaft against the end of the worm shaft, damage to the operator will not result.
