Details of the procedure of turning on and off the ascending operation unit 503u and the descending operation unit 503d also serving as the lighting display member will be described in the configuration of the control device 60 hereinafter.

[Control device 60]
The control device 60 is for controlling the operation of the multi-car elevator device 1, and is constituted by, for example, a computer. The computer is hardware used as a so-called computer. The computer includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). Further, the computer includes a non-volatile storage and a network interface. The control procedure performed by each unit included in the control device 60 is a program stored in the ROM or a program loaded into the RAM from an external device and stored.

  The control device 60 includes three car drive control units 61 that control the movement of the car A1 to C2 by driving the drive pulleys 31a and 32a, an operation mode determination unit 62, a landing function control unit 63, And an output control unit 64.

-Cage drive control unit 61-
One of the three car drive control units 61 synchronizes a pair of drive pulleys 31a and 32a on which a first main rope 41A and a second main rope 42A held by a pair of riding cages A1-A2 are mounted. It is configured to drive control. Similarly, the other one car drive control unit 61 synchronizes a pair of drive pulleys 31a and 32a on which the first main rope 41B and the second main rope 42B are mounted, and further drives one other car. The control unit 61 is configured to control the driving of the pair of drive pulleys 31a and 32a on which the first main rope 41C and the second main rope 42C are mounted in synchronization.

  In particular, the car drive control unit 61 is configured to control the driving of the three sets of drive pulleys 31a and 31b in two operation modes, a normal operation mode and a degenerate operation mode.

  The normal operation mode is an operation mode in which all of the three pairs of riding carts A1-A2, B1-B2, and C1-C2 are circulated in one direction, as shown in FIG. Here, as an example of the normal operation mode, all of the three pairs of riding carts A1-A2, B1-B2, and C1-C2 are circulated in the clockwise circulation direction x. In this case, of the landing doors 11 and 12 shown in FIG. 2, the landing door 11 on the left side is a door only for going up, and the landing door 12 on the right side is a door only for going down.

  On the other hand, FIG. 3 is a schematic configuration diagram illustrating a degenerate operation mode of the multi-car elevator device 1 according to the first embodiment. As shown in this figure, the degenerate operation mode means that, of the three pairs of riding baskets A1-A2, B1-B2, and C1-C2, only one pair of riding baskets A1-A2 reciprocates vertically in the hoistway 10. This is an operation mode for moving. Then, this is an operation mode in which the remaining two pairs of riding cages B1-B2 and C1-C2 are stopped at the upper and lower portions of the hoistway 10 as traveling stops.

  FIG. 4 is a schematic configuration diagram illustrating a floor in the degraded operation mode of the multi-car elevator device 1 according to the first embodiment. In the degenerate operation mode, the landing doors 11 and 12 shown in FIG. 4 are ascending and descending doors, respectively.

  Returning to FIG. 3, the positions where the two pairs of riding cages B <b> 1-B <b> 2 and C <b> 1-C <b> 2 to be stopped in the degraded operation mode are stopped are a retracting part 10 a provided at the upper part of the hoistway 10 and a lower part of the hoistway 10. Is a shunting unit 10b provided in the storage unit. These shelters 10a and 10b are located at positions where the pair of riding baskets A1-A2 does not hinder movement between the lowermost floor F1 and the uppermost floor F4 that stop in the degenerate operation mode. It is assumed that For this reason, the upper refuge 10a sets the interval [D1] required for stopping the riding baskets A1 and A2 moving at the normal speed on the floor F4, for example, at the interval between the riding baskets A1 and A1 stopped on the floor F4. It is provided above A2 and is set higher than A2. In addition, the lower evacuation section 10b sets an interval [D2] required for stopping the riding baskets A1 and A2 moving at the normal speed on the floor F1, for example, of the riding baskets A1 and A2 stopped on the floor F1. It is provided at the lower part and is set lower than that.

  The drive control of the drive pulleys 31a and 32a by the respective car drive control units 61 as described above is performed by the determination result of the operation mode determination unit 62, the operation of the landing call operation units 53a and 53b, and the destinations in the ride baskets A1 to C2. The operation is performed based on an operation of a floor operation unit (not shown) in accordance with an instruction from an input / output control unit 64 described below.

-Driving mode determination unit 62-
The operation mode determination unit 62 is configured to determine whether to switch the operation mode of the riding carts A1 to C2 by the car drive control unit 61 between the normal operation mode and the degenerate operation mode. The determination of the switching of the operation mode by the operation mode determination unit 62 is performed, for example, as follows.

  As a first example, the determination of the switching of the operation mode by the operation mode determination unit 62 is performed based on the driving conditions of the riding baskets A1 to C2. In this case, for example, when the driving frequency of the drive pulleys 31a and 32a by the car drive control unit 61 or the operation frequency of the hall call operation units 53a and 53b falls below a predetermined value, the driving mode determination unit 62 sets the driving pulley 31a, A determination is made to switch the driving of the motor 31b from the normal operation mode to the degenerate operation mode. In addition, the operation mode determination unit 62 determines to switch the driving of the drive pulleys 31a and 31b from the degenerate operation mode to the normal operation mode based on the opposite determination. Thereby, the operation of the multi-car elevator device 1 can be performed in the degraded operation mode without giving a stress to the user of the multi-car elevator device 1, and the running cost of the multi-car elevator device 1 can be reduced.

  As a second example, the determination of the switching of the operation mode by the operation mode determination unit 62 is performed based on the power source type of the electric power used for moving the riding baskets A1 to C2. In this case, for example, a private power generation device is installed in a building in which the multi-car elevator device 1 is installed, and a power supply source for operating the multi-car elevator device 1 is changed from a normal power supply supplied from an electric power company. When the operation mode is switched to the private power generator, the operation mode determination unit 62 determines to switch the driving of the drive pulleys 31a and 31bB from the normal operation mode to the degenerate operation mode. In addition, the operation mode determination unit 62 determines to switch the driving of the drive pulleys 31a and 31b from the degenerate operation mode to the normal operation mode based on the opposite determination. Thus, in an emergency where power supply is restricted, it is possible to restrict the operation of the multi-car elevator device 1 and suppress power consumption.

  As a third example, the determination of the switching of the operation mode by the operation mode determination unit 62 is performed based on an input from the input unit for switching the operation mode. In this case, the operation mode determination unit 62 determines whether an instruction to switch the operation mode from the normal operation mode to the degenerate operation mode or an instruction opposite thereto is input to the input unit (not shown). The switching of the operation mode is determined so as to follow the input. Thus, for example, without stopping the operation of the multi-car elevator device 1, the maintenance of the remaining riding cages B1-B2 and C1-C2 can be performed while the pair of riding cages A1-A2 are driven. .

  In addition to the above, the determination of the switching of the operation mode by the operation mode determination unit 62 may be performed based on a preset time. For example, if the building in which the multi-car elevator device 1 is installed is an office building and there is a large demand for dispatching and moving the cars A1 to C2 in a fixed time zone, the normal operation mode is set in that time zone. Alternatively, the configuration may be such that the operation mode determination unit 62 determines the switching of the operation mode so as to be in the degenerate operation mode other than during the time period.

  In addition, the driving mode determination unit 62 may be configured to perform one determination, a plurality of determinations, or a combination of all determinations among the plurality of determinations described above.

-Park function control section 63-
The landing function control unit 63 is for controlling the landing devices 50 provided on each floor F1 to F4. That is, the hall function control unit 63 controls the operation of the hall call operation units 53a and 53b provided outside the hall doors 11 and 12. The hall function control unit 63 controls lighting, extinguishing, and display of the first display units 51a and 51b, the second display units 52a and 52b, and the hall call operation units 53a and 53b.

  That is, the hall function control unit 63 is configured to control the operations of the hall call operation units 53a and 53b in different operation modes corresponding to the normal operation mode and the degenerate operation mode, respectively. Further, the landing function control unit 63 includes different display modes corresponding to the normal operation mode and the degenerate operation mode, respectively, for the first display units 51a and 51b, the second display units 52a and 52b, and the landing call operation units 53a and 53b. Lighting, turning off, and display are configured to be controlled.

  As described above with reference to FIG. 2, in the normal operation mode, of the landing doors 11 and 12, the landing door 11 on the left side is a door only for going up, and the landing door 12 on the right side is only for going down. Become a door. Therefore, the hall function control unit 63 is provided corresponding to the lift operation unit 503u of the hall call operation unit 53a provided for the hall door 11 and the hall door 12 as the operation mode corresponding to the normal operation mode. Only the descending operation section 503d of the landing call operation section 53b functions.

  The hall function control unit 63 sets the display mode corresponding to the normal operation mode to the ascending display unit 501u of the first display unit 51a provided for the hall door 11 and the ascending operation unit 503u of the hall call operation unit 53a. Only the lighting can be performed at the timing described above. The hall function control unit 63 turns on only the descent display unit 501d of the first display unit 51b and the descent operation unit 503d of the hall call operation unit 53b provided at the landing door 12 at the timing described above. Make it possible.

  On the other hand, as described above with reference to FIG. 4, in the degenerate operation mode, the landing doors 11 and 12 are ascending and descending doors, respectively. Therefore, the hall function control unit 63 includes a hall call operation unit 53a provided corresponding to the hall door 11 and a hall call operation unit provided corresponding to the hall door 12 as operation modes corresponding to the degenerate operation mode. 53b.

  In addition, the landing function control unit 63 sets the display mode corresponding to the degraded operation mode to the ascending display unit 501u and the descending display unit 501d of the first display units 51a and 51b provided corresponding to the landing door 11 and the landing door 12, respectively. Further, the ascending operation unit 503u and the descending operation unit 503d of the hall call operation units 53a and 53b can be turned on. The landing function control unit 63, for example, blinks them or turns them on in a color different from that in the display mode corresponding to the normal operation mode so that the visibility is improved when these are turned on at the timing described above. It is configured to light up.

  Furthermore, as a display mode corresponding to the degenerate operation mode, the hall function control unit 63 causes the second display units 52a and 52b provided corresponding to the hall doors 11 and 12 to perform display. For example, when an elevator car A2 that moves in the ascending direction is assigned to the landing door 12 by operating the landing call operation units 53a and 53b, the landing function control unit 63 displays the second display unit 52b corresponding to the landing door 12 on the second display unit 52b. A blinking symbol mark indicating uphill is displayed.

  As described above, by performing the control of the display mode corresponding to the degraded operation mode, the passenger can easily confirm the target landing door as compared with the case of the normal operation mode. The hall function control unit 63 as described above may be individually provided for each of the floors F1 to F4.

-I / O control unit 64--
The input / output control unit 64 instructs each car drive control unit 61 to drive the drive pulleys 31a and 31b in the normal operation mode or the degenerate operation mode according to the determination by the operation mode determination unit 62. In addition, the input / output control unit 64 instructs the hall function control unit 63 to operate in the operation mode corresponding to either the normal operation mode or the degenerate operation mode, and to display the display mode according to the determination by the operation mode determination unit 62. Instruct the display in. Note that the input / output control unit 64 may be individually provided for each of the floors F1 to F4.

  FIG. 5 is a flowchart illustrating a control method of the multi-car elevator device 1 according to the first embodiment. The control method shown in this figure is realized by causing the control device 60 to execute a program stored in the ROM or the RAM by the CPU constituting the control device 60. Hereinafter, the control method of the multi-car elevator device 1 will be described with reference to the flowchart of FIG. 5 and FIGS.

  First, in step S1 immediately after the operation of the multi-car elevator device 1 is started, the input / output control unit 64 starts the operation in the normal operation mode in which the riding carts A1 to C2 are circulated only in one circulation direction x. . In the next step S2, the input / output control unit 64 determines whether or not there is an instruction to end the operation of the multi-car elevator apparatus 1, and if it is determined that there is an instruction to end the operation (YES), the multi-car elevator The operation of the device 1 is terminated. On the other hand, when the input / output control unit 64 determines that there is no instruction to end the operation of the multi-car elevator device 1 (NO), the process proceeds to step S3.

  In step S3, the operation mode determination unit 62 determines whether to switch to the degenerate operation mode. This determination is performed, for example, as described in the first to third examples. When it is determined that the switching is not performed (NO), the process returns to step S2, and the operation in the normal operation mode is performed as long as it is determined that there is no instruction to end the operation of the multi-car elevator device 1 (NO). continue. On the other hand, when it is determined that the operation mode is to be switched to the degenerate operation mode (YES), the operation mode determination unit 62 proceeds to the next step S4.

  In step S4, the input / output control unit 64 moves the riding cages B1-B2 and C1-C2 to the standby position with respect to the two car driving control units 61 that control the driving of the riding cages B1-B2 and C1-C2.

It is possible to recognize the door effectively. Further, in the degenerate operation mode, it is determined that only one of the pair of riding carts A1 to A2 is to be dispatched, and if the passenger or the building user is made aware of this, the passenger will not be able to reach either of the landings. You don't have to worry about that. Further, since it is not necessary to light or display the landing door (for example, the landing door 12) and the display device (for example, the first display device 51b) on the side where the vehicle is not dispatched, it is possible to further reduce the running cost in the degraded operation mode.
