  As shown in detail in FIG. 4, the elevator control device 31 includes a microcomputer 310, a ROM 311 that stores software codes that serve as means for controlling the elevator, a RAM 312 that stores parameters for control, and input ports 313 and 314. Etc. In the elevator control device 31, control data is generated by calculation in the microcomputer 310, and a control signal is transmitted to the elevator car 1 through the transmission interface 32. In addition, at the input port 313, the magnitude of the earthquake such as the predicted seismic intensity transmitted from the earthquake information prediction device 11 and the predicted arrival time of the main motion are input and stored in the RAM 312, and the control operation is determined based on this. To do. In addition, in the input port 314, the long-period vibration generation prediction signal transmitted from the long-period vibration generation prediction device 14 is input and stored in the RAM 312. Based on this, the control operation for the long-period vibration is determined.

  The transmission interface 32 performs smooth data transmission between the elevator control device 31 and the car 1 or the input / output device 15. As shown in detail in FIG. 5, the microcomputer 320 controls the data transmission. The communication program code is read from the ROM 321, data such as parameters is extracted from the RAM 322, and data transmission processing is performed. The control signal transmitted from the elevator control device 31 in FIG. 3 is temporarily stored in the 2-port RAM 323 and is sequentially taken out. Then, the data is converted by the serial interface 324, and the driver 326 transfers the control signal to the car 1 in FIG. 3. Sent. Data transmitted from the elevator car 1 is received by the receiver 327 and transmitted to the elevator controller 31 via the serial interface 324 and the 2-port RAM 323.

  3 is received by the receiver 329 via the input / output device 15 and transmitted to the elevator control device 31 via the serial interface 325 and the 2-port RAM 323. As shown in detail in FIG. 6, the car call registration device 26 (FIG. 3) operates by the microcomputer 260, reads the program code from the ROM 261, takes out data such as parameters from the RAM 262, and performs transmission processing. The signal of the call button 22 that has been subjected to the car call registration operation on the car operation panel 2 is transmitted to the transmission interface 32 via the input port 263.

  The long-period vibration detecting means 12 can be appropriately selected from known seismometers, vibration detectors, deflection measuring instruments, and the like, for example, in the hoistway 4 or in a building equipment room (not shown). When the long-period vibration detecting means 12 detects long-period vibration, detection information including the maximum amplitude and period is transmitted to the earthquake information database 13 and further via the input / output device 15 and the transmission interface 32. It is transmitted to the elevator control device 31. When the earthquake information database 13 receives the detection information from the long-period vibration detection means 12, the earthquake information database 13 records it as a database together with earthquake information such as magnitude and epicenter position included in the emergency earthquake bulletin 9 received immediately before. The earthquake information database 13 can also include simulation data and past earthquake record data.

  Further, when the elevator control device 31 constituting the elevator control panel 3 receives the detection information (signal) from the long-period vibration detection means 12, control operation control for long-period vibration, for example, in a non-resonant floor, according to the detection information. After the car 1 is moved to a certain fifth floor 75 so that the passenger can be safely lowered, the operation is stopped. When the long-period vibration occurrence prediction device 14 receives the earthquake information from the earthquake information receiving device 10 when an earthquake occurs, the long-period vibration occurrence prediction device 14 is based on the earthquake information from the earthquake information receiving device 10 and the information recorded in the earthquake information database 13. Whether or not a long-period earthquake will occur is predicted, and a long-period vibration detection signal is transmitted to the elevator control device 31. When the elevator control device 31 receives the long-period vibration detection signal, the elevator control device 31 moves the car 1 to the fifth floor 75, which is a non-resonant floor of the building, and then stops the operation.

  Next, the operation of the first embodiment configured as described above will be described. First, in normal operation, operation of the call buttons 22 (221 to 226), the door opening button 23, and the door opening / closing 24 provided on the car operation panel 2 in the elevator car 1 in FIG. The elevator control panel 3 receives the button information and information on the hall call buttons (not shown) provided at the halls 7 (first floor 71 to sixth floor 76) via the transmission interface 32. A normal service is performed by the elevator control device 31. On the other hand, the earthquake information receiving device 10 receives the earthquake early warning 9 including information such as the occurrence time of the earthquake, the position of the epicenter, and the seismic intensity distributed from the Japan Meteorological Agency or the like via communication means such as the Internet or a telephone line. When the earthquake information receiving device 10 receives the emergency earthquake bulletin 9, the earthquake information is transmitted to the earthquake information prediction device 11.

  The earthquake information prediction apparatus 11 is based on the emergency earthquake bulletin 9, and the time at which the initial tremor wave of the earthquake reaches the point according to the registered point, that is, the position where the building is installed. The initial expected tremor arrival time, the main motion arrival time, which is the time when the main motion wave reaches the same point, and the predicted seismic intensity of the seismic wave are obtained by calculation. From the information on the magnitude of the shaking such as the predicted arrival time of the main motion and the predicted seismic intensity of the seismic wave received from the earthquake information prediction apparatus 11, the elevator control device 31, for example, when the predicted seismic intensity exceeds a preset threshold value, A control signal for controlling the elevator during earthquake control is generated and stopped at the nearest stop floor (4th floor 74 in this example) at that time by a drive control device (not shown) via the transmission interface 32. A control operation is performed at the time of earthquake, and the control signal is transmitted to the elevator car 1 to notify the passengers in the car 1 by, for example, the speaker 25 or a display device (not shown).

  FIG. 7 is a flowchart showing a specific example of the control operation selection operation when the elevator control device 31 receives a long-period vibration detection signal. When the elevator performing normal operation in step S1 receives the detection signal of the long-period vibration detecting means 12 for detecting long-period vibration of the building in step S2, the elevator 1 is moved to the nearest stop floor in step S3. Stop and get off the passengers. After stopping at the nearest stop floor in step S3, referring to the vibration detection level of the long-period vibration detection means 12 in step S4, if the detection level of the long-period vibration is equal to or higher than a travelable threshold (Yes), In step S5, the elevator operation is stopped at the nearest stop floor because it is impossible to travel.

  In step S4, if the detected vibration detection level of the long-period vibration detection means 12 is less than the threshold value (No), it is determined that the vehicle can travel, and the car 1 is affected by the long-period vibration of the building in step S6. It moves to a few non-resonant floors (5th floor 75), and in step S5, the operation of the elevator is stopped at the non-resonant floor (5th floor 75). In step S2, if the detection signal from the long-period vibration detection means 12 has not been received (No), and the emergency earthquake bulletin 9 has not been received in step S7 (No), The normal operation that is the operation of is continuously executed. Moreover, when the earthquake early warning 9 is received in step S7 (Yes), the predicted seismic intensity and the predicted arrival time are calculated from the emergency earthquake early warning 9 in step S9, and the predicted seismic intensity calculated in step S10 is compared with the threshold value. When the predicted seismic intensity is smaller than the threshold value (No), the normal operation that is the current elevator operation is continued in step S8.

  In step S10, the predicted seismic intensity is compared with the threshold value. If the predicted seismic intensity is larger than the threshold value (Yes), the first seismic control operation for immediately stopping the elevator at the nearest stop floor is performed in step S11. When stopping at the nearest stop floor in step S11, the long-period vibration occurrence predicting device 14 may generate long-period vibration using the received information on the emergency earthquake warning 9 and the earthquake information recorded in the earthquake information database 13. And a long-period vibration generation prediction signal is transmitted to the elevator control device 31. In step S12, when the elevator control device 31 does not receive the long-period vibration generation prediction signal (No), the elevator performs operation stop at the nearest stop floor in step S5. In step S12, when the elevator control device 31 receives the long-period vibration generation prediction signal (Yes), in step S6, the car 1 is directed to the non-resonant floor (the fifth floor 75) before the long-period vibration is generated. Then, the operation shifts to the second seismic control operation that travels and stops, and the speaker 25 notifies that fact, and the operation is stopped at the non-resonant floor (the fifth floor 75) in step S5.

  As described above, the elevator operation control system for an earthquake according to the present invention can use the earthquake early warning 9 delivered from the Japan Meteorological Agency or the like immediately after an earthquake, and can be derived from the earthquake early warning before the seismic wave reaches the elevator. The elevator will be controlled during an earthquake, such as quickly stopping the car 1 to the nearest stop floor using the estimated time of arrival of the main movement. Furthermore, when the long-period vibration of the building is detected by the long-period vibration detection means 12, the nearest stop floor or the building vibration moves to a non-resonant floor where the elevator does not affect the elevator. At that time, the information included in the earthquake early warning 9 and the long-period vibration detection information are recorded in the earthquake information database 13, and when another earthquake early warning is received, the received data of the recorded earthquake information database 13 is distributed. Long-period vibration is predicted by the long-period vibration generation prediction device 14 based on the emergency earthquake bulletin 9, and the control operation at the time of the earthquake is performed for the long-period vibration.

  Therefore, according to the first embodiment of the present invention, by performing an emergency earthquake control operation using an emergency earthquake warning, the elevator can be shifted to a stop operation earlier, and passenger safety can be improved. In addition, by predicting the occurrence of long-period vibrations, it is possible to perform control operations for long-period vibrations, such as by waiting for the elevators to a position where the effects of resonance due to long-period vibrations are small, almost immediately after the occurrence of an earthquake. The possibility of damage to the elevator equipment can be further reduced.

  In the first embodiment, the explanation has been made centering on the emergency operation of the elevator by the earthquake early warning 9 provided by the Japan Meteorological Agency or the like. For example, a conventional earthquake detection device (not shown) using a wave detector, an accelerometer, etc. is further provided, and the elevator control device 31 constantly monitors the operation of the earthquake detection device and the reception of the emergency earthquake warning 9 to When the earthquake bulletin 9 is received first, the earthquake control operation is performed as exemplified in the first embodiment. For example, the earthquake detection device is first activated without receiving the emergency earthquake bulletin due to a communication line failure or the like. When an earthquake is detected, or when the epicenter is close to the building and the earthquake sensing device senses an earthquake earlier than the reception of the earthquake early warning 9, the detection signal of the earthquake sensing device is Flip be controlled to perform a seismic control operation with desirable.
