- the rotational speeds of the hoisting machines 4a and 4b are detected by speed detectors 9a and 9b, respectively, and the tensions of the ropes 5a and 5b are detected by load detectors 10a and 10b, respectively.
- the load detectors 10a and 10b function as a weighing device that detects the load in the car by measuring the displacement of the panel that expands and contracts when the load increases or decreases when the passenger gets in and out of the car 6. Since the panel displacement is in principle proportional to the rope tension, the rope tension is measured and it also functions as a tension detector.
- the hoisting motors la and lb are driven and controlled by a drive control device 11.
- the drive control device 11 determines the traveling pattern of the car 6 and sends a speed command, and compares the speed command from the operation management unit 12 with the speed detection value by the speed detectors 9a and 9b.
- the speed control units 13a and 13b that calculate the torques to be output by the two lifting motors la and lb, respectively, and send torque commands, and the lifting motors la according to the torque commands from the speed control units 13a and 13b Power control that controls the power supplied to the hoisting motors la and lb according to the commands from the torque control units 14a and 14b and the torque control units 14a and 14b. It consists of vessels 15a and 15b.
- the elevator control system of the present invention outputs a feedback control signal to the drive control device 11 according to the tension difference between the two ropes detected by the load detectors 10a and 10b as tension detectors.
- a compensator 16 for controlling the rotational speed of the hoisting motors la and lb is provided. This compensator 16 increases the rotational speed of at least one lifting machine only when the tension difference between the two ropes detected by the load detectors 10a and 10b as the tension detector exceeds a predetermined value.
- a feedback control signal is output to the drive control device 11 for control, and the rotation speed is increased due to the difference in the rope tension, and the speed of the upper lifting motor is decreased so as to adjust to the lower level. .
- FIG. 2 is a block diagram showing an internal configuration of the compensator 16.
- the compensator 16 is sent from the operation management unit 12 to the speed control unit 13 (generically 13a and 13b).
- a compensation element 18 that sends a compensation amount of gain K according to the tension difference between the two ropes detected by the load detectors 10a and 10b as tension detectors, Based on the speed detection values from the detectors 9a and 9b and the Tonlek command from the speed control units 13a and 13b, the hoist with a low speed is selected as a reference, and the compensation amount of the gain K of the compensation element 18 is reduced.
- the speed controllers 13a, 13b are based on the speed difference or speed feedback of both the upper aircraft.
- the difference between the Tonlek command values output from each is smaller than the predetermined value, the gain of the compensation element 18 is reduced and the gain K is not corrected, thereby making the dynamics insensitive to the torque difference, that is, the eccentric load.
- Compensation calculation Unit 19 and an abnormality detection unit 20 for determining an abnormality when the compensation amount from compensation element 18 is greater than a predetermined value and sending an emergency stop command.
- the operation management unit 12 determines a traveling pattern of the force 6 and outputs a speed command to the speed control unit 13.
- the speed control unit 13 compares the speed command from the operation management unit 12 and the rotational speeds of the two lifting machines 4a and 4b (the lifting motors la and lb) detected by the speed detectors 9a and 9b. In comparison, the torques to be output by the two lifting motors la and lb are calculated, and torque commands are sent to the torque control units 14a and 14b.
- the torque control units 14a and 14b operate the power converters 15a and 15b in accordance with the respective Tonerek commands to control the torques generated by the motors la and lb.
- the brakes 2a and 2b are operated to stop the rotation of the sheaves 3a and 3b, and the power supply to the hoisting motors la and lb is cut off to perform a series of operations. finish.
- the springs 8a and 8b are for preventing vibration propagation from the ropes 3a and 3b to the car 6 and ensuring a comfortable ride for passengers.
- the springs 8a and 8b expand and contract when a person in the car 6 gets on and off and the load increases or decreases. Therefore, the load in the car can be detected by measuring the displacement of the panel. You can. This panel displacement is proportional to the rope tension in principle, so the rope tension is measured.
- the load detectors 10a and 10b apply, for example, this principle and detect the tension of the ropes 3a and 3b, respectively. There are other methods for detecting the rope tension, and the invention described here does not depend on the detection method.
- the compensator 16 should control the rotational speed of at least one hoisting machine only when the tension difference between the two ropes exceeds a predetermined value.
- a feedback control signal is output to the drive control device 11, and works to lower the speed of the hoisting motor with the higher rotational speed and lower it according to the difference in rope tension.
- the compensation element 18 allows the compensation amount of the gain K for the speed command sent from the operation management unit 12 to the speed control unit 13 (13a and 13b are collectively referred to) according to the tension difference between the two ropes.
- the dynamic compensation calculation unit 19 uses the hoisting machine with a low speed as a reference. By selecting and compensating the gain K of the compensation element and reducing the gain of the higher speed aircraft, the speed of both the upper aircraft, that is, the rope tension, is made to match.
- the load detectors 10a and 10b as the balance device for detecting the load in the force ring also serve as the tension detector, the load detector 10a, 10b can be configured at low cost. It is possible to check for malfunctions when the scale is detected.
- the safe side can be designed by compensating for the direction of lowering the speed.
