TH35287A - Elevator door control device - Google Patents

Abstract

DC60 (10/08/41) in an elevator door control device that controls the closing force that will be generated by the driving motor. Door in response to deviation between speed commands for door movement And the output of the speed detector for detecting the gate speed, its improvement is in such a way that the closing force generated by the motor is reduced to zero when there is no effect. The exit of the speed detector is detected under the condition of the occurrence of speed commands. According to this invention, passengers caught by the door can be safely guarded without The lack of overall elevator performance In the elevator door control device, it controls the closing force that is generated by the driving motor. The door in response, but the deviation between the speed commands for the door movement. And the output of the speed detector for detecting the gate speed, its improvement is in such a way that the closing force generated by the motor is reduced to zero when there is no effect. The exit of the speed detector is detected under the condition of the occurrence of speed commands. According to this invention, passengers caught by the door can be safely guarded without The lack of overall elevator performance

Claims (5)

1.Elevator door control device Which activates and closes the door by driving a motor that is driven. The gate follows the command value of the motor voltage, which is sent out in response to the deviation between the command values. The gate speed, which was calculated in response to the gate opening and closing command, and the actual door speed, which This was achieved by detecting the rotational speed of the motor that drives the gate. Whose characteristics are Elevator door control devices are also provided. The control path, which is given when the door speed command value is a predetermined value, and when the actual speed of the door is 0 continuously for the specified time, the opening and closing torque is given. Give the door a zero by setting Zero of the motor voltage command value It is a set period of time and when the number of times the motor's rated difference command is set to zero exceed the set number of times. Which outputs fault signals to keep the elevator in resting state and another control path, which As a result, when the door was manually moved after the elevator was In the state of rest by the previous control path and when the switch for detecting the closed and open ends of the door was operated under the condition where the actual speed of the door was not zero, output stopped Of the fault signal and returned to the elevator to normal operation from the rest state. 2. Elevator door control device according to claim 1 that has the characteristics of Door control device The elevator is equipped with a counter which counts the number of times for setting up the process of command values. The motor potential difference is zero when the motor speed is zero continuously. The period specified under the condition that the motor voltage command value is set to zero in an interval. The time limit 3. The elevator door control device according to claim 2 has a unique feature that the counter is reset. When a negative value is detected it is the motor speed under the condition where the motor voltage command value is set to zero for a set period of time. 4. Elevator door control device according to claim 2, which is characterized by an excess of count. That time has been determined An error contract was sent out. 5. The elevator door control device according to claim 4, which is characterized by: Under no matter what conditions The door-end detection path or the door-end detection path can detect up to Door open end Or the end of the door closed due to the operation of opening and closing of the door after being done Provide an output of the fault signal When the motor speed which was detected is other than zero, the counter is reset.
