Description

  The present invention relates to an earthquake control operation recovery system that efficiently implements an operation of recovering an earthquake control operation that operates when an earthquake occurs.

At the time of the current earthquake, in order to keep the elevator in a normal condition, it is necessary to inspect with specialized maintenance personnel.
Specialized maintenance personnel return after inspection.

  In addition, it has been proposed that a check operation is automatically performed when an earthquake occurs, and a normal operation can be restored if there is no safety problem.

Further, in the inspection operation after the occurrence of an earthquake, an obstacle detection device is provided above and below the car, the speed of the earthquake inspection operation is set at a very low speed, and the elevator is stopped when an obstacle is detected.
JP-A-6-227770 (paragraph numbers 009 to 023, FIGS. 1 to 5) JP 2002-128408 A (drop number 006-034, FIGS. 1-5)

  According to the above-mentioned conventional technology, inspection operation is automatically performed after the occurrence of an earthquake, and if there is no problem, it is returned to normal, so if there is a bent rail or a derailed rail, etc. Etc., and the condition is further deteriorated.

  In addition, although the above-described inconvenience can be solved by providing an obstacle detection device, there is a problem that the time required for the inspection increases because the inspection operation of the earthquake always runs at a very low speed.

  An object of the present invention is to provide a seismic control operation recovery system that can safely and quickly perform seismic control operation recovery work.

  To achieve the above objective, connected to the seismic detector that operates when an earthquake is detected, the seismic control operation device that performs seismic control operation that stops the elevator at the nearest floor when the seismic detector operates, and the control panel that controls the elevator Recovering seismic control operation with a monitoring terminal that detects elevator abnormalities and machine inspections, and a monitoring center that is connected to multiple monitoring terminals via a communication line and performs elevator abnormality monitoring and machine inspection diagnostic management The system comprises safety device detection means for detecting the operation of a safety device that stops the elevator tonight when operated, and motor load determination means for detecting that the running motor load exceeds a threshold, at least the safety device being When the motor load is within a threshold value with no operation, a seismic control operation cancel command for canceling the seismic control operation is provided, and the seismic control operation canceling means The inspection operation of the elevator that has been released from the seismic control operation is provided with an operation command means at the time of an earthquake that makes the speed at the position where the car and the counterweight intersect each other very slow, and the seismic control operation release command is reset at the monitoring center It is possible.

  Since it did in this way, check the operation of the safety device and check the motor load determination means for abnormalities such as the counterweight coming off the rail due to the increase in motor load during travel, and cancel the earthquake control operation Therefore, it is not necessary to return the switch of the seismic detector, the slow speed operation at the time of inspection operation is only at the position where the car and the counterweight intersect, and it is canceled when the earthquake occurs again after the earthquake control operation restoration work, etc. Seismic control operation can be returned at the monitoring center.

  According to the present invention, when it is detected that the elevator can travel safely in the earthquake control operation restoration work, the operated earthquake control operation is canceled, and the speed of the inspection operation is also only at the position where the car and the counterweight intersect. Since the speed is very low, the earthquake control operation can be restored safely and in a short time, and the seismic control operation in the event of an aftershock can also be performed at the monitoring center, so that the safety of elevator users can be improved.

  Hereinafter, the recovery system for seismic control operation will be described with reference to the drawings. FIG. 1 is a configuration diagram showing the configuration of a recovery system for seismic control operation. In addition, in each figure, the same code | symbol shows the same or equivalent part.

A main rope 10, a position detection device 11 for detecting that the position of the car 1 is in the door zone, and a guide rail (for the car) 12 for guiding the vertical movement of the car 1. A guide rail (for counterweight) 13 for guiding the counterweight 9 to move up and down, a load detecting means 14 for detecting the load of the motor driving the car, and a business connected to the monitoring center 6 via the telephone line 5 A personal computer 15, a safety device 16 that detects that the elevator has operated abnormally and stops the elevator, and a temporary restoration site storage unit 17 that stores the site that is connected to the monitoring center 6 and temporarily restored after the inspection operation.

  In the load detection device for detecting the load amount of the 14 motors, the load amount is detected by a current or torque flowing through the motor.

  Also, in the figure, the monitoring terminal 4 has a processing device 41, a ROM 42, a RAM 43, and an input / output device 44, and a storage means for storing a standard value of the car drive motor load during the inspection operation. The comparison determination performed by the ROM 42 and comparing the detection value detected by the load detection device 14 with the standard value stored in the ROM 42 to determine whether the deviation value between them is equal to or greater than a certain value is a processing device 41 (corresponding to a comparison determination means). ) Do.

  Moreover, the monitoring terminal 4 can change the traveling speed of the elevator via the control panel 3, and can be arbitrarily changed to a low-speed traveling that travels at, for example, 15 m / mim and a low-speed traveling that travels at, for example, 5 m / min. Have.

  Next, the earthquake control operation recovery system will be described with reference to the drawings. FIG. 2 is a flowchart showing the entire processing procedure of the restoration system for the seismic control operation.

  First, when an earthquake occurs and the seismic detector 7 is activated (step 100), the control panel 3 stops the traveling car 1 at the nearest floor, opens the door 2, and a predetermined time when the passenger will get off. Later, the door 2 is closed.

  Next, after a certain period of time has elapsed since the earthquake (step 101), the maintenance staff at the sales office issues an inspection operation start command to the monitoring terminal 4 from the personal computer 15 at the sales office via the monitoring center 6 (step 102). .

  Next, the monitoring terminal 4 determines whether the seismic sensor 7 is operating only on the first contact or the second contact (step 103), and only the first contact is operating, that is, the local seismic intensity. If the value is equal to or less than the predetermined value, the process proceeds to step 104. If the second contact is also operating, the process proceeds to step 106.

  Next, the monitoring terminal 4 determines from the information on the control panel 3 whether the elevator was running or stopped when the earthquake occurred (step 104). If the elevator was running when the earthquake occurred, the process proceeds to step 105, If stopped, the process proceeds to step 106.

  Next, the monitoring terminal 4 determines whether the safety device 16 is operating from the information on the control panel 3 (step 105). If the safety device 16 is operating, the process proceeds to step 106, and if it is not operating Then, go to Step 107.

  If the monitoring terminal 4 determines that the elevator inspection operation is impossible, the monitoring terminal 4 continues to stop the elevator (step 106) and proceeds to step 114.

  Further, the monitoring terminal 4 determines that the elevator inspection operation is possible, and the earthquake detector 7 is electrically short-circuited (step 107), the inspection operation is performed (step 108), and the process proceeds to step 109. Details of the processing at this time will be described later with reference to FIG.

  Next, it is determined whether the monitoring terminal 4 has detected an abnormality in the elevator (step 109). If an abnormality in the elevator is detected, the process proceeds to step 116, and if not detected, the process proceeds to step 110.

  Next, the monitoring terminal 4 transmits the travel result such as the motor load during the inspection operation to the sales office personal computer 16 via the monitoring center 6 (step 110).

  Next, a specialized maintenance staff determines whether it is safe to return the elevator from the result of the inspection operation displayed on the sales office personal computer 16 (step 111). If it is determined that it is not safe, the process proceeds to step 117.

  Next, the electrical short circuit of the earthquake sensor 7 is maintained, the elevator is temporarily restored, and temporary restoration information is stored in the temporary restoration site storage unit 17 provided in the monitoring center 6 by the monitoring terminal 4 via the telephone line 5. (Step 112), and the monitoring center 5 informs a specialized maintenance staff via the personal computer 16 of the sales office that the site registered in the temporary recovery site storage unit 17 needs to be handled (step 113). Then, a specialized maintenance staff mechanically restores the earthquake detector 7 and finishes the process (step 114).

  If an abnormality in the elevator is detected in step 109, the elevator is automatically stopped by the monitoring terminal 4, the electrical short circuit of the earthquake detector 7 is released (step 115), and the process proceeds to step 117.

  On the other hand, if a specialized maintenance staff judges that the elevator is abnormal or if an earthquake is detected again at the temporary restoration site, the elevator is stopped at the monitoring terminal 4 via the monitoring center 6 by the sales office personal computer 16, and the earthquake is stopped. The electrical short circuit of the sensor 7 is released (step 116), and a specialized maintenance person rushes to the site to check whether the elevator is safe (step 117).

  If the safety of the elevator is confirmed in step 117, the process proceeds to step 119. If the abnormality is confirmed, the process proceeds to step 118.

  Next, repair of the elevator is performed by a specialized maintenance staff (step 118), and the specialized maintenance staff carries out a process of restoring the earthquake detector 7 (step 119).

  This completes the entire process of the earthquake control operation recovery system.

  Next, the process at the time of inspection operation of the recovery system for seismic control operation will be described. FIG. 3 is a flowchart showing a processing procedure at the time of inspection operation of the earthquake control operation recovery system of FIG.

  First, the monitoring terminal 4 lowers the car 2 to the lowest floor by low-speed operation (step 200). When the monitoring terminal 4 detects that the car 2 has arrived at the lowest floor (step 201), the monitoring terminal 4 The car 2 is raised to the top floor by low speed operation (step 202), and when the monitoring terminal 4 detects that the car 2 has arrived at the top floor (step 203), the car 2 is moved to the bottom floor by the monitoring terminal 4. It is lowered by low speed operation (step 204).

  Next, when the monitoring terminal 4 detects that the car 2 has arrived at the lowest floor (step 205), the monitoring terminal 4 raises the car 2 to the top floor by high speed operation (step 206). When the monitoring terminal 4 detects arrival at the floor (step 207), the monitoring terminal 4 lowers the car 2 to the lowest floor by high speed operation (step 208).

  Next, when the monitoring terminal 4 detects that the car 2 has arrived at the top floor, the inspection operation is terminated (step 209).

  Details of the processing at the time of low speed operation in Step 200, Step 202 and Step 204 will be described later with reference to FIG.

  This completes the inspection operation processing of the earthquake control operation restoration system.

FIG. 4 is a flowchart showing a low-speed operation processing procedure during the inspection operation of the earthquake control operation recovery system of FIG.

  First, low-speed operation is started (step 300), and the load amount of the car drive motor 8 detected by the motor load amount detection means 14 by the processing device 41 of the monitoring terminal 4 and the car drive during the inspection operation stored in the ROM 42 are detected. The standard value of the load amount of the motor 8 is compared (step 301), and if the deviation value between the detected value and the standard value is equal to or greater than a certain value, the process proceeds to step 309. Proceed to 302.

  Next, the monitoring terminal 4 determines whether or not the current position of the car 2 is in the vicinity of the position detection device 11 or the counterweight 9 (step 302). If not, return to step 300.

  Next, the traveling speed of the elevator is switched from low speed to full speed by the monitoring device 4 (step 303), and the load amount of the car drive motor 8 detected by the motor load amount detection means 14 by the processing device 41 of the monitoring terminal 4; The standard value of the load amount of the car drive motor 8 during the inspection operation stored in the ROM 42 is compared (step 304), and if the difference value between the detected value and the standard value is a certain value or more as a result of the comparison, The process proceeds to step 309, and if it is equal to or smaller than the predetermined value, the process proceeds to step 305.

  Next, the monitoring terminal 4 determines whether or not the current position of the car 2 is in the vicinity of the position detection device 11 or the counterweight 9 (step 305). Return to step 306 if it is not near.

  Next, the traveling speed of the elevator is switched from a very low speed to a low speed by the monitoring device 4 (step 306), the load amount of the car drive motor 8 detected by the motor load amount detecting means 14 by the processing device 41 of the monitoring terminal 4, and the ROM 42 Is compared with the standard value of the load amount of the car drive motor 8 during the inspection operation stored in (step 307), and if the deviation value between the detected value and the standard value is greater than or equal to a certain value, the process proceeds to step 309, where the constant value If it is the following, go to Step 308.

  Next, the monitoring terminal 4 determines whether the current position of the car 2 has arrived at the destination floor (step 308). If it has arrived at the destination floor, the process is terminated. Return.

  In step 309, if the deviation between the detected value and the standard value is large, the elevator guide rail (car) 12 or the guide rail (balance weight) 13 is bent, or the car 2 or the balance weight 9 is Since there is a high possibility of an abnormality in the elevator such as deviation from the guide rail (for the car) 12 or the guide rail (for the counterweight) 13, the elevator is stopped at the nearest floor in the direction opposite to the traveling direction.
