摘要： A pulse generator is coupled to a car drive motor directly coupled to a sheave, over which a rope suspending an elevator car is passed, and the position of the car is calculated through the counting of pulses produced from the pulse generator. First and second car position detectors for detecting respective first and second car positions are provided within a hatchway, and the number of pulses produced during a period from the actuation of the first car position detector till the actuation of the second car position detector is detected. A count value for calculating the car position is corrected according to the difference between the detected pulse number and a reference pulse number corresponding to the distance between the first and second car position detectors, thereby effecting the compensation for the wear of the sheave and rope to improve the precision of the car position detection.

摘要： In an elevator control system, in which the elevator car is controlled on the basis of elevator car positions obtained through the counting of distance pulses provided in proportion to the distance travelled by the car and floor height data indicative of the heights of individual floors, the distance pulses are counted by moving the car at a low speed from the lowest floor to the highest floor, and the count at the time of the actuation of a floor position detector, which is actuated when the car passes by each floor, is stored as the floor height value of that floor in a RAM (Random Access Memory). With this arrangement, the measurement of the floor heights is facilitated, and also the preparation of a ROM (Read-Only Memory) for storing the floor height data for each elevator car is made needless to promote the standardization.
摘要翻译：在电梯控制系统中，电梯轿厢是根据通过计算由轿厢行驶的距离成比例地提供的距离脉冲获得的电梯轿厢位置和指示各楼层的高度的楼层高度数据来控制的，通过将轿厢从最低楼层移动到最高楼层来计算距离脉冲，并且当轿厢经过每层楼时启动的地板位置检测器的启动时的计数被存储为 RAM（随机存取存储器）中该楼层的楼层高度值。通过这种布置，便于对地板高度的测量，并且不需要准备用于存储每个电梯轿厢的楼层高度数据的ROM（只读存储器）来促进标准化。

摘要： A bridge circuit including a couple of thyristors and a two diodes is connected between a three-phase ACpower supply and a three-phase induction motor for driving an elevator car. The bridge circuit is adapted to make up a controlled rectifier circuit or an inverse-parallel connection circuit of thyristors, as the case may be, by switching a plurality of contactors. At the time of starting and accelerating the elevator car, the bridge circuit is changed to constitute an inverse-parallel connection circuit of thyristors to which a signal for a sufficiently high speed command is applied. This speed command is applied to a phase shifter, which fires the thyristors in inverse-parallel connection at a sufficiently large conduction angle. In consequence, the three-phase induction motor produces a sufficiently large accelerating torque, so that the car is accelerated according to differences between the accelerating torque and the elevator car load torque. When the accelerated car reaches a deceleration-starting point, the speed command in changed to another command decelerating the car at a predetermined rate toward a destination. At the same time, the phase shifter is changed over to receive a deviation signal between the speed command signal and the output signal of the tachometer generator connected to the motor. The inverse-parallel connection of thyristors is changed over to the controlled rectifier circuit connection. The motor is thus decelerated by a speed feedback control system of a DC braking type.
