Next, the main part of the 2 nd system 3 will be described with reference to fig. 2.
Fig. 2 is a configuration diagram of a main part of a 2 nd system of the landing power supply system of the elevator according to embodiment 1.
As shown in fig. 2, the 2 nd system 3 includes a plurality of landing power supply systems 19. The landing power supply system 19 includes a wiring branching substrate 20. The wiring branching board 20 is provided to branch the 2 nd ac power supply wiring 14, the 2 nd dc power supply wiring 16, and the 2 nd communication signal wiring 17 to each floor. At the uppermost layer of each group, the 2 nd landing power supply 11 is provided to the landing power supply system 19. At the uppermost layer of each group, the switching device 12 is provided on the wiring branching substrate 20.
The 2 nd landing display control panel 13 includes a control board 21. The control board 21 includes a microcomputer 23. The control board 21 includes a landing-side determination unit 22 at the lowest layer of each group.
At the lowest floor of each group, the landing side determination unit 22 receives a signal from the elevator control panel 4 indicating disconnection or connection. The microcomputer 23 controls the operation of the switching device 12 of the next-lower adjacent group based on the signal received by the hall-side determining unit 22.
The elevator control panel 4 includes a panel-side determination unit 24 and a panel-side control unit 25.
The control panel side determination unit 24 determines whether or not ac power is supplied to the 2 nd landing power supply 11 of each group. The control panel side determination unit 24 transmits a cut-off signal or a restoration signal to the 2 nd layer station display control panel 13 of the group other than the uppermost group based on the determination result of itself. The control panel side control unit 25 controls the operation of the switching device 12 of the uppermost group based on the control panel side determination result.
According to embodiment 1 described above, the 2 nd landing display control panel 13 connects and disconnects the 2 nd ac power supply wiring 14 to and from the 2 nd landing power supply 11 with respect to the switching device 12 corresponding to the 2 nd landing power supply 11 other than the 2 nd landing power supply 11 that supplies dc power to itself. Accordingly, the supply of ac power to the unused group can be cut off. As a result, energy saving can be achieved more reliably with a low-cost structure.
Specifically, at the lowest layer of each group, the 2 nd landing display control panel 13 controls the operation of the switching device 12 of the group adjacent below via the control signal wiring 18. Therefore, energy saving can be more reliably measured, and the number of the 2 nd station power sources 11 and the number of the 2 nd ac power source wirings 14 can be reduced.
The elevator control panel 4 transmits a restoration signal to the group 1 switching device 12 via the control signal wiring 18. In group 1, the switching device 12 connects the 2 nd ac power supply wiring 14 to the 2 nd landing power supply 11 according to the resume signal. Therefore, even when the supply of ac power to all the 2 nd station power sources 11 has been cut off, the supply of ac power to the 2 nd station power sources 11 can be resumed without ensuring power.
The power supply 11 and the switching device 12 for the 2 nd landing may be provided for each of the plurality of 2 nd landing display control panels 13. In this case, energy saving can be achieved more reliably.
In addition, the 2 nd layer display control panel 13 other than the lowermost layer may be selected from each group as the 2 nd layer display control panel 13 for connecting and disconnecting the 2 nd ac power supply wiring 14 to and from the 2 nd layer power supply 11 with respect to the switching device 12 corresponding to the 2 nd layer power supply 11 other than the 2 nd layer power supply 11 for supplying dc power to itself. In this case, energy saving can be achieved more reliably.
The 2 nd ac power supply wiring 14 may be connected in the order of group 4, group 3, group 2, and group 1. In this case, the elevator control panel 4 may control the switching device 12 of the 4 th group via the control signal wiring 18. In this case, energy saving can be achieved more reliably.
