As shown in FIG. 2, the landing call buttons 3 on the 1st to 15th floors transmit binary signals different from each other when operated. Specifically, the detection signal during energy saving standby and the detection signal when the landing call button 3 on the 1st to 15th floors is operated are H level or L level for four signal lines. At this time, the combination of the H level or the L level for the four signal lines has 16 patterns so as to be able to distinguish between the energy saving standby and the operation of the landing call button 3 on the 1st to 15th floors. As a result, the car device control device 11 and the control device 17 can detect the operated landing call.

Next, the operation of the control device 17 will be described with reference to FIG.
FIG. 3 is a flowchart for explaining the operation of the control device of the elevator system according to the first embodiment.

In step S1, the control device 17 determines whether or not the condition for shifting the operation mode of the elevator to the energy saving mode is satisfied. If the condition for shifting the elevator operation mode to the energy saving mode is not satisfied in step S1, the control device 17 performs the operation of step S1. When the condition for shifting the operation mode of the elevator to the energy saving mode is satisfied, the control device 17 performs the operation of step S2.

In step S2, the control device 17 cuts off the supply of electric power from the power source to the elevator. After that, the control device 17 performs the operation of step S3. In step S3, the control device 17 determines whether or not any of the plurality of landing call buttons 3 has been operated.

If none of the plurality of landing call buttons 3 is operated in step S3, the control device 17 performs the operation of step S3. When any of the plurality of landing call buttons 3 is operated in step S3, the control device 17 performs the operation of step S4.

In step S4, the control device 17 restarts itself. After that, the control device 17 performs the operation of step S1.

Next, the operation of the car device control device 11 will be described with reference to FIG.
FIG. 4 is a flowchart for explaining the operation of the car device control device of the elevator system according to the first embodiment.

In step S11, the car device control device 11 determines whether or not the energy saving mode transition preparation command from the control device 17 has been received. If the energy saving mode transition preparation command from the control device 17 is not received in step S11, the car device control device 11 performs the operation of step S11. When the energy saving mode transition preparation command from the control device 17 is received in step S11, the car device control device 11 performs the operation of step S12.

In step S12, the car device control device 11 supplies electric power from the emergency battery 23. After that, the car device control device 11 performs the operation of step S13. In step S13, the energy saving mode transition completion signal is transmitted to the control device 17.

After that, the car device control device 11 performs the operation of step S14. In step S14, the car device control device 11 determines whether or not any of the plurality of landing call buttons 3 has been operated. When none of the plurality of landing call buttons 3 is operated in step S14, the car device control device 11 performs the operation of step S14. When any of the plurality of landing call buttons 3 is operated in step S14, the car device control device 11 performs the operation of step S15.

In step S15, the car device control device 11 determines whether or not the floor on which the operated landing call button 3 is provided and the floor on which the car 4 is stopped are the same. If the floor on which the landing call button 3 operated in step S15 is provided and the floor on which the car 4 is stopped are not the same, the car device control device 11 operates in step S14. When the floor on which the landing call button 3 operated in step S15 is provided and the floor on which the car 4 is stopped are the same, the car device control device 11 operates in step S16.

In step S16, the car device control device 11 opens the car door 5. After that, the car device control device 11 ends the operation of the car device control device 11.

According to the first embodiment described above, when the floor on which the landing call button 3 is provided and the floor on which the car 4 is stopped are the same, the car device control device 11 re-controls the control device 17. The car door 5 is opened before the activation is completed. Therefore, on any floor, the car 4 in front of the user can be made to open the car door 5 in a short time from the energy saving mode.

If the floor on which the landing call button 3 is provided and the floor on which the car 4 is stopped are not the same, the car device control device 11 does not open the car door 5. Therefore, it is possible to prevent the car door 5 from opening unnecessarily.

Further, the car device control device 11 determines the floor on which the car 4 is stopped by using the power of the emergency battery 23 in a state where the power supply from the power supply P is cut off. Therefore, it is possible to more reliably determine the floor where the car 4 is currently stopped.

The car device control device 11 opens the car door 5 using the electric power from the power source P before the restart of the control device 17 is completed. Therefore, the power consumption of the emergency battery 23 can be suppressed.

Further, the plurality of landing call buttons 3 transmit different binary signals from each other. Therefore, the operated landing call button 3 can be detected with a smaller number of wires than the number of landing call buttons 3.

When the elevator is in operation, the lighting device 7 may be turned on by using the electric power from the power source P. When the power supply from the power source P is cut off, the lighting device 7 may be turned off. After that, when one of the plurality of landing call buttons 3 is operated to transmit a signal using the electric power from the emergency battery 23, the lighting device 7 is turned on before the restart of the control device 17 is completed. Just let me do it. As the electric power at this time, the electric power from the power source P may be used. In this case, not only can the car 4 in front of the user open the car door 5 in a short time from the energy saving mode, but also the inside of the car 4 can be brightened.
