    摘要： An elevator system includes a microprocessor-based cab controller mounted directly on an elevator car, which controls the operation of the elevator door. Elevator door motion is commanded in response to the difference in actual door velocity from a desired, dictated door velocity in accordance with desired rates of acceleration and deceleration, and desired maximum velocity, acceleration and deceleration, the point at which deceleration is to begin, and a velocity at which decleration is to decrease. The disclosed invention provides a bench velocity, a final, slow velocity, by controlling the velocity at which deceleration is to decrease, so that the acceleration vs time of the profile exceeds the deceleration vs time of the profile by an amount resulting in the desired, final bench velocity. An exemplary elevator system, an exemplary microprocessor-based controller, and logic flowcharts for an overall door control program, illustrative of an environment of the invention, as well as details of the invention, are disclosed herein.

    摘要： An actual position value transmitter for an elevator position control circuit includes a pulse transmitter in the form of a digital tachometer which is driven by way of a cable and a car distance counter responsive to the pulses for generating an actual position signal. Stopping errors of the elevator car caused by slip of the cable are avoided by utilizing a correction table in the form of a write-read memory, in which correction values assigned to the floors and corresponding to the stopping errors are stored. The correction table is connected to the car distance counter and on departure of the elevator car from a floor or on passing a floor, a correction value assigned to the next floor is fetched from the correction table and fed to the car distance counter for the purpose of correction of the actual position signal.

    摘要： An elevator system includes a microprocessor-based cab controller mounted directly on an elevator car, which controls the operation of the elevator door. Elevator door motion is commanded in response to the difference in actual door velocity from a desired, dictated door velocity in accordance with desired rates of acceleration and deceleration, maximum velocity, acceleration and deceleration, the point at which deceleration is to begin, and a velocity at which deceleration is to decrease. The disclosed invention provides selective modification in maximum velocity along with the point at which deceleration is to begin, the velocity at which deceleration is to decrease along with the point at which deceleration is to begin, and/or simply the point where deceleration is to begin, so that door velocity profiles may be tailored to suit any particular door of a given type. An exemplary environment for and details of the present invention are disclosed.

    摘要： Provided are a control system for an electric lifting desk and an electric lifting desk. The control system includes a controller and a motor driver circuit, and the controller includes a microprocessor, a measured voltage acquisition circuit and a measured voltage acquisition terminal. The motor driver circuit is configured to drive the lifting of at least one column, and the motor driver circuit includes a measured voltage generation circuit and a measured voltage output terminal. When the number of columns and/or the column type of the electric lifting desk is different, the value of a measured voltage output by the measured voltage generation circuit is different. The microprocessor is configured to determine whether the controller is connected to the motor driver circuit according to a voltage signal provided by the measured voltage acquisition circuit, and to determine the number of columns and/or the column type.
