Definitions
- Elevator systems are equipped with a governor and an emergency stop device to constantly monitor the ascending and descending speed of the car and bring the car to an emergency stop if it becomes overspeeding to a certain extent.
- the car and the governor are connected by a governor rope, and when an overspeeding state is detected, the governor restrains the governor rope, activating the emergency stop device on the car side and bringing the car to an emergency stop.
- the elevator system of the present invention comprises a car, an emergency stop device provided in the car, and an electric actuator that activates the emergency stop device, and also comprises a first control device that detects and stores the running state of the car during a power outage, and a second control device that returns the electric actuator that was activated in response to the power outage to a standby state based on the running state stored by the first control device.
- elevator equipment equipped with an electric emergency stop device can be smoothly restored when power is restored.
- FIG. 1 is a schematic configuration diagram of an elevator system according to an embodiment of the present invention
- FIG. 2 is a plan view showing a mechanism of the electric actuator according to the embodiment.
- 1 is an operational state diagram showing an example of the operation of an elevator car of an embodiment during a power outage and upon power restoration.
- 4 is a flowchart showing a processing operation of the safety control device in the embodiment at the time of a power outage. 4 is a flowchart showing a processing operation for returning an electric operating device to a normal state in the elevator control device according to the embodiment.
- an image sensor may be used as the speed sensor.
- the position and speed of the car 1 are detected based on image information of the surface condition of the guide rail 4 acquired by the image sensor. For example, the speed is calculated from the moving distance of the image feature in a given time.
- the drive shaft 12 is driven by the biasing force of the drive spring 13 (Fig. 1) in the direction from the fixed part 14 (Fig. 1) to the pressing member (Fig. 1) received by the pressing member 15 (Fig. 1) of the drive shaft 12.
- the first link member (operating lever 11 and first operating piece 16: Fig. 1) connected to the drive shaft 12 rotates around the first operating shaft 19 (Fig. 1).
- the second link member (connecting piece 17 and second operating piece 18: Fig. 1) connected to the drive shaft 12 rotates around the second operating shaft 20 (Fig. 1). This causes the lifting rod 21 (Fig. 1) connected to the second operating piece 18 to be pulled up.
- the motor control device 112 has a drive circuit for the motor 37 and controls the rotation of the motor 37 in response to a control command from the elevator control device 7.
- the motor 37 may be either a DC motor or an AC motor.
- the monitoring device 600 monitors the operating status of the elevator equipment based on information held by the elevator control device 7. When an abnormality occurs in the elevator equipment, the monitoring device 600 transmits an abnormality alert signal and information on the operating status indicating the abnormality via the communication network 700 to a monitoring server 801 installed in a control center 800 located geographically away from the installation location of the elevator equipment.
- the electric actuator 10 When the emergency stop device 2 is deactivated, the electric actuator 10 returns to the standby state by driving the electromagnet 35a to return the movable element to the standby position.
- the elevator control device 7 is equipped with a computer system such as a microcomputer, independent of the safety control device 103. This computer system executes a specific program, causing the elevator control device 7 to execute the recovery process for the electric actuator 10.
- step S402 the elevator control device 7 determines whether data related to the running state of the car 1 during a power outage, i.e., data on the running direction, speed, and position, is stored in the non-volatile memory device 130 in the safety control device 103. Therefore, in step S402, the elevator control device 7 determines whether the safety control device 103 has executed the power outage processing described above (FIG. 5).
- step S405 the elevator control device 7 uses the monitoring device 600 to report an abnormality to the monitoring server 801 installed in the control center 800, and puts the elevator device into a pause state.
- step S403 If the elevator control device 7 determines that the travel direction, speed, and position data are stored (YES in step S402), it then executes step S403.
- step S406 determines that the traveling direction is not a downward direction, that is, that the traveling direction is an upward direction or the car 1 is stopped and the return operation of the electric operator 10 is possible (NO in step S403), it then executes step S406.
- step S404 determines that the speed of the car 1 is equal to or greater than the threshold value (YES in step S404), i.e., that it is difficult to restore the electric actuator 10, it next executes step S405.
- the elevator control device 7 uses the monitoring device 600 to report an abnormality to the monitoring server 801 installed in the control center 800, and puts the elevator device into a paused state.
- step S404 determines that the speed of the car 1 is not equal to or greater than the threshold (NO in step S404), that is, that the return operation of the electric actuator 10 is possible, it then executes step S406.
- step S406 the elevator control device 7 determines whether the current position of the car 1 is lower than the position of the car 1 before it stopped at the time of the power outage, which is stored in the non-volatile memory device 130, based on data regarding the running state of the car 1 obtained from the non-volatile memory device 130 provided in the safety control device 103.
- the elevator control device 7 regards the stopping position of the car 1 at the time of the power outage, which is stored in the non-volatile memory device 130, as the current position of the car 1. Furthermore, if there are multiple pieces of position data before the car 1 stops at the time of the power outage, the position before the car 1 stops at the time of the power outage is the position indicated by any one of the multiple pieces of data. Therefore, in step S406, the elevator control device 7 determines whether the car descended during the power outage.
- step S407 the elevator control device 7 operates the car 1 in the upward (UP) direction. At this time, the elevator control device 7 controls the upward operation of the car 1 based on the position of the car 1 stored in the non-volatile memory device 130.
- step S408 the elevator control device 7 uses the motor control device 112 to rotate the return motor (motor 37 in FIG. 2) forward and reverse, as described above, to return the electric operator 10 to the standby state.
- the safety control device 103 which controls the electric operator 10 to activate the emergency stop device 2, detects and stores the running state of the car 1 during a power outage, and when power is restored, the elevator control device 7 returns the electric operator 10 to a standby state according to the running state of the car 1 stored by the safety control device 103.
- the elevator control device 7 returns the electric operator 10 to a standby state according to the running state of the car 1 stored by the safety control device 103.
- the safety control device 103 detects and stores the running state of the car 1 during a power outage, but a control device for detecting the running state during a power outage may be provided independent of the safety control device 103. Since the safety control device 103 has a function for emergency stopping the car 1 according to the running state of the car 1, even if it further has a function for executing the power outage processing as shown in FIG. 5, the number of parts such as microcomputers does not increase.
- the elevator system may have a machine room, or it may be a so-called machine room-less elevator that does not have a machine room.
