Description

  The present invention relates to an elevator operation control device during an earthquake.

  None of the conventional elevator seismic sensing devices have been able to perform a sufficiently satisfactory control operation of the elevator because they take measures against the earthquake after sensing that an actual earthquake has occurred. In any case, it is most important to know as soon as possible that an earthquake will occur in the control operation of the elevator. The earlier the earthquake is detected, the safer and more reliable the operation of the operating elevator is. Obviously it can be done.

  In addition, as conventional technology, the earthquake information receiving means for receiving real-time earthquake information including at least the epicenter and the time of occurrence of the earthquake determined from the seismic wave, and the information contained in the real-time earthquake information received by the earthquake information receiving means from the current location An elevator earthquake control operation system having an earthquake prediction means for predicting the arrival time of an earthquake wave and a control means for controlling the control operation of the elevator according to the earthquake arrival time predicted by the earthquake prediction means is known. (For example, see Patent Document 1).

  In a conventional elevator earthquake control operation system, real-time earthquake information based on seismic waves can be used to predict the time of an earthquake and to detect an earthquake sufficiently early, thereby enabling safe elevator operation. However, since no countermeasures have been taken after the elevator has stopped in such a controlled operation, even if the elevator can be safely stopped at the nearest floor, damage may occur due to the shaking of the earthquake after the stop.

  The present invention has been made to solve the above-described problems, and can predict the time of an earthquake using real-time earthquake information based on seismic waves, and can detect an earthquake sufficiently early to perform control operation. For elevators that have been stopped due to control operation in an elevator, a standby mode is provided to prepare for the arrival of an earthquake, thereby providing an elevator operation control device during an earthquake that minimizes earthquake damage after the stoppage. is there.

Reference numeral 12 denotes a car connecting portion that connects the governor rope 7 and the car 1, and 13 is a guide roller provided in the car 1, for example, using an active roller guide, and the guide reaction force of the car 1 is increased. It is increased so that it can cope with the roll load of an earthquake, preventing the rail from being removed or the guide from shifting. Although not shown, the guide roller provided on the counterweight 5 side has the same configuration. 14 is a real-time earthquake information transmitting device, 15 is a real-time earthquake information receiving means, 16 is an earthquake sensing unit, 17 is an elevator control panel, 18 is a control operation control unit provided in the control panel 17, and 19 is provided in the control panel 17. The car state storage unit 20, the car position storage unit 20 provided in the car state storage unit 19, the operation state storage unit 21 provided in the car state storage unit 19, and the control panel 17 It is an earthquake standby operation control unit provided.

Next, the basic operation of the elevator earthquake control operation device will be described with reference to the flowchart of FIG.
First, when the elevator is in normal operation (step S1), when the real-time earthquake information receiving device 15 receives real-time earthquake information (step S2), if the car 1 is running (step S3), earthquake control is performed. The operation stops at the nearest floor (step S4). Next, the car state storage unit 19 stores the car state (step S5). If the car 1 is not traveling in step S3, the process proceeds to step S5, and the car state is stored in the car state storage unit 19. Next, if a passenger is in the car 1, an operation for lowering the passenger to the stop floor is performed (step S6), and then the door is closed (step S7). Then, in the next step S8, the earthquake standby operation according to the present invention is started. If it is determined in step S9 that a predetermined time has elapsed and the shaking due to the earthquake has converged, the process proceeds to step S10, and a recovery operation corresponding to the magnitude of the earthquake is performed. If the shaking due to the earthquake has not converged at step S9, the earthquake standby operation at step S8 is continued.
As the earthquake standby operation in step S8, for example, the guide reaction force of the car 1 and the counterweight 5 is increased so as to be able to cope with the roll load of the earthquake, thereby preventing the rail from being removed and the deviation of the guide. At this time, an active roller guide may be used as the guide roller 13.
In addition, when the building shakes due to the earthquake and the rope largely rolls in resonance with the shake, in the case of the main rope 2, the car 1 or the counterweight 5 is connected to the governor rope 10 in the case of the main rope 2. In this case, the governor rope tensioning wheel 11 swings up and down, and in the case of the balancing rope 7, the balancing wheel 8 swings up and down. Therefore, during the earthquake standby operation in advance, the car 1 and the counterweight 5 are locked by an emergency stop (not shown), and the governor rope tensioning vehicle 11 and the countercar 8 have the rope tension. Operate to increase. Since the emergency stop can lock only the downward movement, it may be locked by adding an upward emergency stop. At this time, the force and operation generated during standby may be changed according to the magnitude of the earthquake and the frequency of shaking predicted from the earthquake information.
In this way, by providing an earthquake standby operation mode in preparation for an earthquake that reaches after the stop for an elevator that is stopped by control operation using real-time earthquake information, it is possible to minimize earthquake damage after the stop. .

The case where the nearest floor can be stopped before the earthquake arrives by the operation of the elevator operation control system during an earthquake will be described with reference to the flowchart of FIG.
First, when the elevator is operating normally (step S11), when the real-time earthquake information receiving device 15 receives real-time earthquake information (step S12), if the car 1 is traveling (step S13), an earthquake arrives. It is determined whether or not it is possible to stop at the nearest floor before (step S14), and if it is determined that it is possible to stop at the nearest floor before the earthquake reaches, it is stopped at the nearest floor by seismic control operation (step S15). Next, the car state storage unit 19 stores the car state (step S16). Next, if a passenger is in the car 1, an operation of lowering the passenger to the stop floor is performed (step S17), and then the door is closed (step S18). Then, in the next step S19, the earthquake standby operation according to the present invention is started. If it is determined in step S20 that the predetermined time has elapsed and the shaking due to the earthquake has converged, the process proceeds to step S21 to determine whether there is a passenger. If the shaking due to the earthquake has not converged at step S20, the earthquake standby operation at step S19 is continued. If there are no passengers in step S21, a recovery operation corresponding to the magnitude of the earthquake is performed (step S22). If it is determined in step S21 that there is a passenger, the vehicle stops at the nearest floor (step S23), performs an operation to lower the passenger to the stop floor (step S24), and then closes the door (step S25). In step 22, a restoration operation corresponding to the magnitude of the earthquake is performed. If the car 1 is not traveling in step S13, the process proceeds to step S26, the car state is stored in the car state storage unit 19, and then the process proceeds to step S17. If it is determined in step S14 that the nearest floor cannot be stopped before the earthquake arrives, the process proceeds to step S27, where it is determined whether the seismic intensity in the earthquake detector 16 is, for example, seismic intensity 5 or higher. If there is an emergency stop (step S28), the car state is stored in the car state storage unit 19 (step S29), and then the earthquake standby operation in step S19 is started. In step S27, if the seismic intensity in the earthquake detection unit 16 is less than, for example, seismic intensity 5, the process proceeds to step S15 and stops at the nearest floor by seismic control operation.
The earthquake standby operation in step S19 is substantially the same as step S8 in FIG.

Embodiment 2. FIG.
FIG. 4 is a flow chart for explaining the operation of the elevator earthquake control operation apparatus according to Embodiment 2 of the present invention.
The case where there is a sufficient time margin before the nearest floor stops before the earthquake arrives in the operation of the elevator operation control system during an earthquake will be described with reference to the flowchart of FIG.
First, when the elevator is in normal operation (step S31), when the real-time earthquake information receiving device 15 receives real-time earthquake information (step S32), if the car 1 is running (step S33), an earthquake arrives. It is determined whether or not it is possible to stop at the nearest floor before (step S34), and if it is possible to stop at the nearest floor, it is determined whether or not there is sufficient time before stopping at the nearest floor (step S34). S35). If it is determined that there is not enough time, it stops at the nearest floor by the seismic control operation (step S36). Next, the car state storage unit 19 stores the car state (step S37). Next, if a passenger is in the car 1, an operation of lowering the passenger to the stop floor is performed (step S38), and then the door is closed (step S39). Then, in the next step S40, the earthquake standby operation according to the present invention is started. If it is determined in step S41 that the predetermined time has elapsed and the shaking due to the earthquake has converged, the process proceeds to step S42 to determine whether there is a passenger. If the shaking due to the earthquake has not converged at step S41, the earthquake standby operation at step S40 is continued. If no passenger is present in step S42, a recovery operation corresponding to the magnitude of the earthquake is performed (step S43). If it is determined in step S42 that there is a passenger, the vehicle stops at the nearest floor (step S44), performs an operation to lower the passenger to the stop floor (step S45), and then closes the door (step S46). In step 43, a restoration operation corresponding to the magnitude of the earthquake is performed. If the car 1 is not running in step S33, the process proceeds to step S47, the car state is stored in the car state storage unit 19, and then the process proceeds to step S38. If it is determined in step S34 that the nearest floor cannot be stopped before the earthquake arrives, the process proceeds to step S48, where it is determined whether the seismic intensity in the earthquake detector 16 is, for example, seismic intensity 5 or higher. If there is an emergency stop (step S49), the car state is stored in the car state storage unit 19 (step S50), and the earthquake standby operation in step S40 is started. In step S48, if the seismic intensity in the earthquake sensing unit 16 is less than seismic intensity 5, for example, the process proceeds to step S36 and stops at the nearest floor by seismic control operation.
If there is sufficient time before the nearest floor stops before the arrival of the earthquake in step S35, the process proceeds to step S51 to set the safest and most suitable nearest floor of the elevator. The elevator will be stopped at the nearest safe and optimal floor.
The earthquake standby operation in step S40 is substantially the same as step S8 in FIG.
