  The elevator control devices 1A and 1B are set to output a restoration signal to the seismic control operation command device 12 even when it is detected that the mobile terminal device 20 is detached from the terminals 2Aa and 2Ba. The seismic control operation command device 12 cancels the test mode and returns to the normal mode in response to the restoration signal from the elevator control devices 1A and 1B, and outputs the test mode release signal to the elevator control devices 1A and 1B and the earthquake detector 8. It is set to be. The elevator control devices 1A and 1B and the earthquake detector 8 are set to cancel the test mode in accordance with the test mode cancel signal and return to the normal mode.

  The earthquake control operation command device 12 includes a communication device 13D, and can communicate with the control center 15 via the communication device 13D. The mobile terminal device 20 can communicate with the control center 15.

  The seismic control operation test is conducted as follows. Here, an earthquake control operation test for Unit 1 A will be described as an example.

  As shown in FIG. 3, first, when a maintenance person gets on the car 2A of the first car A and connects the mobile terminal device 20 to the terminal 2Aa (step S1), the elevator control device 1A of the first car A becomes the mobile terminal device 20 Is detected (procedure S2 → procedure S3 → procedure S4a). Along with this, the elevator control devices 1A and 1B switch from the normal mode to the first unit test mode and output a mode switching command signal to the seismic control operation command device 12.

  When receiving the mode switching command signal, the earthquake control operation command device 12 switches from the normal mode to the test mode (step S5), and outputs a switching completion signal to the elevator control device 1A and the earthquake detector 8.

  When the elevator control devices 1A and 1B receive the switching completion signal from the seismic control operation command device 12, the elevator control devices 1A and 1B enter a test preparation completion state (step S6). The test preparation completion state in the elevator control device 1A of Unit 1 A is a state in which the acceleration information for testing from the mobile terminal device 20 can be relayed, and the earthquake control operation is performed in accordance with the command from the earthquake control operation command device 12 It is. The test preparation completion state in the elevator control device 1B of Unit 2 B is a state in which the command for the earthquake control operation from the earthquake control operation command device 12 is invalidated.

  When the seismic detector 8 receives the switching completion signal from the seismic control operation command device 12, the seismic detector 8 switches from the normal mode to the test mode (step S7).

  The maintenance staff in the car 2A looks at the screen displayed on the monitor of the mobile terminal device 20 to confirm that the preparation completion signal is input to the mobile terminal device 20, and then operates the mobile terminal device 20 to operate the mobile terminal device 20A. The pitch test acceleration information and the roll test acceleration information are transmitted to the elevator control apparatus 1A (step S8). The test acceleration information is transmitted to the seismic control operation command device 12 by relay of the relay means 1Ab of the elevator control device 1A, and further functions as an acceleration imparting means of the seismic control operation command device 12, thereby making the seismic control. It is given to the earthquake detector 8 from the operation command device 12. Accordingly, in the earthquake detector 8, the earthquake information creation means (the calculation / control device 11A and the storage device 11B) creates test information based on the test acceleration information given from the earthquake control operation command device 12, This test earthquake information is output to the earthquake control operation command device 12 (step S9).

  When the earthquake control operation command device 12 receives the test earthquake information from the earthquake detector 8, the earthquake control operation command device 12 commands the elevator control device 1A to perform the earthquake control operation corresponding to the test earthquake information (step S10). That is, as shown in FIG. 4, when the seismic control operation command device 12 inputs the test earthquake information from the earthquake detector 8 (step S101), first, the test acceleration information indicated by the test earthquake information is obtained. It is determined whether it indicates pitch or roll (step S102). When the test earthquake information indicates acceleration that is equal to or greater than the pitch threshold, the elevator controller 1A is commanded to perform seismic control operation during pitching (procedure S102 → procedure S103 → procedure S104). If the test earthquake information indicates acceleration that is equal to or greater than the roll threshold, the elevator controller 1A is commanded to perform seismic control operation during roll (step S102 → step S105 → step S106). When the acceleration indicated by the seismic control operation is not equal to or greater than the threshold value, the seismic control operation is not instructed regardless of the pitching or rolling (NO in step S103 or NO in step S105).

  Returning to FIG. 3, the elevator control device 1 </ b> A executes the earthquake control operation when receiving the command of the earthquake control operation from the earthquake control operation command device 12 (step S <b> 11). During the execution of the seismic control operation test, seismic control operation information indicating the operation status of Unit 1 A is transmitted to the mobile terminal device 20.

  The mobile terminal device 20 displays the earthquake control operation information from the earthquake control operation command device 12 on the monitor (step S12). The maintenance staff confirms whether the earthquake control operation is normally performed from the earthquake control information displayed on the monitor of the mobile terminal device 20 and the actual operation of the car 2A.

  Thereafter, when the maintenance staff removes the portable terminal device 20 (procedure S13), the elevator control device 1A detects this (procedure S14), and outputs a restoration signal to the seismic control operation command device 12. When receiving the restoration signal, the earthquake control operation command device 12 cancels the test mode, returns to the normal mode (step S15), and outputs the test mode release signal to the elevator control devices 1A and 1B and the earthquake detector 8. To do. When the elevator control devices 1A and 1B receive the test mode cancel signal, the elevator control devices 1A and 1B cancel the first unit test mode and return to the normal mode (step S16). The earthquake detector 8 also returns to the normal mode when the test mode release signal is input (step S17).

  When the portable terminal device 20 is connected to the terminal 2Ba of the second machine B, the elevator control devices 1A and 1B enter the second machine test mode, and the earthquake control operation test of the second machine B is performed in the same manner as in the first machine mode described above. Will be able to do.
