Embodiment 1.
FIG. 1 is a configuration diagram of an elevator 1 according to the first embodiment.

The elevator 1 is applied, for example, to a building having multiple floors. A hoistway 2 for the elevator 1 is provided in the building. The hoistway 2 is a vertically long space that spans multiple floors. A landing 3 adjacent to the hoistway 2 is provided on each floor of the building.

The elevator 1 includes one or more units 4. In this example, the elevator 1 includes multiple units 4. Each unit 4 includes a hoist 5, a main rope 6, a car 7, a counterweight 8, and a control panel 9.

The hoisting machine 5 includes a motor that generates a driving force, and a sheave that rotates by the driving force generated by the motor. The hoisting machine 5 is disposed, for example, at the upper or lower part of the hoistway 2. Alternatively, when a machine room is provided in the elevator 1, for example, above the hoistway 2, the hoisting machine 5 may be disposed in the machine room.

The main rope 6 is a rope that supports the load of the car 7 and the counterweight 8 in the hoistway 2. The main rope 6 is wound around the sheave of the hoisting machine 5. The main rope 6 receives the load of the car 7 on one side of the sheave of the hoisting machine 5. The main rope 6 receives the load of the counterweight 8 on the other side of the sheave of the hoisting machine 5.

The car 7 is a device that transports users of the elevator 1 between multiple floors by traveling vertically through the hoistway 2. The car 7 is equipped with a scale 10 and a buzzer 11. The scale 10 is a device that measures the load of the car 7. The buzzer 11 is a device that issues an audio alert when the load measured by the scale 10 exceeds a preset threshold value. The counterweight 8 is a device that balances the loads applied to both sides of the sheave of the hoisting machine 5 between the car 7 and the counterweight 8. The car 7 and the counterweight 8 travel in opposite directions through the hoistway 2 by the driving force generated by the motor of the hoisting machine 5.

The control panel 9 is a part that controls the operation of the unit 4 that includes the control panel 9. The operation of the unit 4 includes, for example, the raising and lowering of the car 7. The control panel 9 is disposed, for example, at the top or bottom of the elevator shaft 2. Alternatively, if a machine room is provided, the control panel 9 may be disposed in the machine room.

A control system 12 is applied to the elevator 1. The control system 12 includes a control panel 9 for each unit 4. The control system 12 includes a plurality of hall devices 13. In this example, the control system 12 includes a group management device 14.

Each of the hall equipment 13 corresponds to one of a plurality of floors. Each of the hall equipment 13 is provided at the hall 3 of the corresponding floor. The hall equipment 13 is equipment that accepts operations performed by users and the like at the hall 3 of the corresponding floor. The hall equipment 13 may be equipped with a function of displaying information to users and the like at the hall 3 of the corresponding floor. The hall equipment 13 is equipped with a function of transmitting a signal representing the accepted operation. In this example, the hall equipment 13 transmits a signal to one of a plurality of input ports of the group management device 14. The hall equipment 13 belongs to one or a plurality of systems. Each system is a set of hall equipment 13 that transmits a signal representing the accepted operation to a common input port. Each system includes a plurality of hall equipment 13, each corresponding to a plurality of floors. In this example, the control system 12 includes two systems, system A and system B.

The group control device 14 is a device that controls the operation of the elevator 1. The group control device 14 is arranged in the building in which the elevator 1 is installed. The group control device 14 may be arranged, for example, at the top or bottom of the elevator shaft 2, or in a machine room if a machine room is provided.

Figure 2 is a block diagram showing the configuration of the control system 12 according to embodiment 1.

Each hall device 13 includes a faceplate 15, a display panel 16, operation buttons 17, and a hall board 18.

The faceplate 15 is a plate-like part that hides the internal equipment such as the hall board 18 from users of the hall 3. The faceplate 15 is arranged, for example, on the wall surface of the hall 3. The front surface of the faceplate 15 faces the hall 3. The display panel 16 is provided on the front surface of the faceplate 15. The display panel 16 is a part that displays information such as the position of the car 7 and the traveling direction of the car 7 to users of the hall 3. The operation button 17 is provided on the front surface of the faceplate 15. The operation button 17 is a push button or the like that accepts operations performed by users of the hall 3. In this example, the hall equipment 13 has two operation buttons 17, an up button and a down button.

The hall board 18 is a part that processes information in the hall equipment 13. The hall board 18 is disposed behind the faceplate 15. The hall board 18 is disposed, for example, in a storage box embedded in the wall of the hall 3. At this time, the storage box and the hall board 18 are hidden from users of the hall 3 by the faceplate 15. The hall board 18 includes a unique information storage unit 19, an operation determination unit 20, and a first communication unit 21.

The unique information storage unit 19 is a part that stores unique information that is unique to each hall equipment 13. The unique information is, for example, a serial number that is assigned to the hall equipment 13 when it is manufactured.

The operation determination unit 20 is a part that determines an operation performed by a user of the hall 3 or the like. The operation determination unit 20 determines which operation button 17, for example the up button or the down button, has been pressed. In this example, the operation determination unit 20 distinguishes between a normal operation and a special operation. The normal operation is an operation of registering a hall call from the hall 3 where the hall equipment 13 is provided. The normal operation is, for example, an operation of pressing the operation button 17 and then releasing it before a preset long press time has elapsed. The special operation is an operation different from the normal operation. The special operation is, for example, an operation of pressing the operation button 17 and then releasing it after a long press time has elapsed. The long press time is, for example, 5 seconds. Alternatively, the special operation may be, for example, an operation of pressing the up button and the down button a preset number of times and in a preset order.

The first communication unit 21 is a part that communicates with devices external to the hall equipment 13. When the operation determination unit 20 determines an operation, the first communication unit 21 transmits information on the determined operation and the unique information stored in the unique information storage unit 19. The first communication unit 21 transmits, as operation information, the determination result as to which operation button 17, for example the up button or the down button, has been pressed. The first communication unit 21 also transmits, as operation information, the determination result as to whether, for example, a normal operation or a special operation has been performed.

The group management device 14 includes a mode switching unit 22, a correspondence memory unit 23, a second communication unit 24, an allocation unit 25, a floor identification unit 26, a car selection unit 27, a system selection unit 28, and a correspondence setting unit 29.

The mode switching unit 22 is a part that switches the operation mode of the elevator 1. The mode switching unit 22 is, for example, a change-over switch. The elevator 1 includes a normal mode and a write mode as operation modes. The normal mode is an operation mode in which the elevator 1 performs normal operation. In normal operation, users of the elevator 1 get into the car 7 and move between multiple floors. The write mode is an operation mode in which floor setting work is performed. The floor setting work is a work of associating the unique information of each hall equipment 13 with one of multiple floors. The floor setting work is performed, for example, when installing a new elevator 1, or when repairing or updating an existing elevator 1.

The correspondence memory unit 23 is a part that stores the unique information of each hall device 13 in association with one of multiple floors. The correspondence memory unit 23 stores a correspondence table T. In this example, the correspondence memory unit 23 stores a correspondence table T for each route. The correspondence between the unique information and the floor is written in the correspondence table T. In this example, the unique information "XXX" is associated with the "2nd floor". Also, the unique information "YYY" is associated with the "1st floor".

The second communication unit 24 is a part that communicates with devices external to the group management device 14. In this example, the second communication unit 24 has multiple input ports that receive information such as unique information from each hall device 13.

The allocation unit 25 is a part that allocates hall calls. Hall calls are allocated, for example, as follows:

When the elevator 1 is in normal mode, a user normally operates the up button of the hall equipment 13 at the hall 3 on the first floor, for example. At this time, the operation determination unit 20 in the hall board 18 of the hall equipment 13 determines that the up button has been normally operated. After that, the first communication unit 21 transmits to the group management device 14 the unique information "YYY" read from the unique information storage unit 19 together with information indicating the normal operation of the up button.

The second communication unit 24 of the group management device 14 receives the unique information "YYY" from the hall equipment 13. The allocation unit 25 reads the corresponding floor "1st floor" from the correspondence memory unit 23 by referring to the correspondence table T using the unique information "YYY" received by the second communication unit 24 as a key. The allocation unit 25 detects that a hall call operation for an upper floor has been performed on the 1st floor based on the floor read by the unique information and the information received by the second communication unit 24 together with the unique information. The allocation unit 25 allocates a hall call for an upper floor with the 1st floor as the departure floor to one of the multiple units 4. The control panel 9 of the unit 4 to which the hall call has been allocated registers the hall call so that the car 7 of the unit 4 responds.

The floor specification unit 26 is a part that acquires the floor at which the reference car is stopped. The reference car is the car 7 of one of the units 4. The reference car is selected, for example, by a worker performing floor setting work. Alternatively, the reference car may be the car 7 of a specific unit 4 that has been preselected, such as the first car. The target stopping position of the car 7 at each floor is prestored in the control panel 9 of each unit 4. The control panel 9 of each unit 4 specifies, for example, the floor of the target stopping position closest to the position at which the car 7 is stopped as the floor at which the car 7 is stopped. Alternatively, for example, when the car 7 stops at any floor due to a car call, the control panel 9 of each unit 4 may specify the floor specified as the destination floor of the car call as the floor at which the car 7 is stopped. The floor specification unit 26 inquires of the control panel 9 of the unit 4 including the reference car about the floor at which the reference car is stopped. In this way, the floor identification unit 26 identifies the floor on which the reference car is stopped based on the response from the control panel 9 of the unit 4 including the reference car. Alternatively, the floor identification unit 26 may store the target stopping positions on each floor for the car 7 of each unit 4 in advance. In this case, the floor identification unit 26 obtains the position of the reference car from the control panel 9 of the unit 4 including the reference car. The floor identification unit 26 identifies the floor of the target stopping position closest to the obtained position of the reference car as the floor on which the reference car is stopped.

The car selection unit 27 is a part that selects a reference car. The car selection unit 27 is, for example, a switch that selects a unit 4 that includes a reference car. The system selection unit 28 is a part that selects a system to which the hall equipment 13 that is to be associated with a floor in the floor setting work belongs. The system selection unit 28 is, for example, a switch that selects a system. The system selection unit 28 may be capable of selecting all systems in the elevator 1.

The correspondence setting unit 29 is a part that associates the unique information of the hall equipment 13 with the floors in the floor setting work. The correspondence setting unit 29 performs the association by writing to the correspondence table T. For example, the correspondence setting unit 29 writes to the correspondence table T as follows.

When starting floor setting work, the worker switches the operation mode of the elevator 1 to the write mode using the mode switching unit 22. At this time, the worker selects the reference car using the car selection unit 27. The worker also selects the system to which the matching will be performed using the system selection unit 28. For example, when matching all hall equipment 13 in the installation of a new elevator 1, the worker selects all systems. Alternatively, when matching some hall equipment 13 in the repair or renewal of an existing elevator 1, the worker selects the system to which the hall equipment 13 to be matched belongs. In this example, the worker matches the hall equipment 13 located on the third floor of system A.

After switching to the write mode, the worker moves the selected reference car to the third floor where the hall equipment 13 to be associated is located. At this time, the worker may get in the reference car and move to the third floor. The worker may also move the reference car to the third floor by registering a car call for the third floor by operating a car operation panel installed in the reference car, for example.

The worker performs a special operation on the operation button 17 of the hall equipment 13 at the hall 3 on the third floor. For example, the worker presses the operation button 17, and then releases it after a long press time has elapsed. The operation button 17 operated at this time may be either the up button or the down button. In the hall board 18 of the hall equipment 13, the operation determination unit 20 determines that the operation button 17 has been operated in a special way. After that, the first communication unit 21 transmits to the group management device 14 the unique information "ZZZ" read from the unique information storage unit 19 and information indicating the special operation of the operation button 17.

The second communication unit 24 of the group management device 14 receives unique information from the hall equipment 13 at an input port connected to the hall equipment 13. The correspondence setting unit 29 determines the system to which the hall equipment 13 belongs based on the input port to which the unique information is input from the hall equipment 13. If the determined system is not the A system selected by the system selection unit 28, the correspondence setting unit 29 does not perform the correspondence process. On the other hand, if the determined system is the A system selected by the system selection unit 28, the correspondence setting unit 29 determines whether the operation represented by the information input together with the unique information is a special operation.

If the operation determined by the correspondence setting unit 29 is not a special operation, the correspondence setting unit 29 does not perform the correspondence process. On the other hand, if the operation determined by the correspondence setting unit 29 is a special operation, the floor identification unit 26 identifies the floor on which the reference car is stopped as the "third floor." The floor identification unit 26 outputs the identified floor to the correspondence setting unit 29.

The correspondence setting unit 29 judges whether the unique information corresponding to the output floor has already been written in the correspondence table of the A system determined by the input port. If it is judged that the unique information corresponding to the output floor has already been written in duplicate, the correspondence setting unit 29 does not write to the correspondence table T. At this time, the correspondence setting unit 29 notifies the worker of the failure of the writing. The correspondence setting unit 29 notifies the worker, for example, by sounding the buzzer 11 of the reference car. At this time, the buzzer 11 of the reference car is an example of an alarm unit. On the other hand, if it is judged that the unique information corresponding to the output floor has not yet been written, the correspondence setting unit 29 writes to the correspondence table T. The correspondence setting unit 29 writes the unique information transmitted from the hall equipment 13 to the correspondence table T of the A system determined by the input port in association with the floor output from the floor identification unit 26. Here, if the unique information transmitted from the hall equipment 13 has already been written in the correspondence table T, the correspondence setting unit 29 overwrites the unique information and the correspondence between floors.

Here, if another system B is also selected by the system selection unit 28, the worker may perform a special operation on the operation button 17 of the hall equipment 13 belonging to system B and located on the third floor while the reference car is stopped on the third floor. In this way, matching of hall equipment 13 of multiple systems located on the same floor may be performed in parallel.

In addition, if there is a hall equipment 13 for which matching is to be performed at another floor, the worker moves the reference car to that floor while maintaining the write mode. At this time, the worker may get on the reference car and move to that floor. At this time, the order of floors for which matching is performed may be changed depending on, for example, the relationship with other work performed in parallel with the floor setting work. In the floor setting work, matching for all floors does not have to be performed at once. The floor setting work may be paused depending on, for example, the relationship with other work performed in parallel with the floor setting work. While the floor setting work is paused, the operating mode of the elevator 1 may be switched to normal mode.

Figure 3 is a flowchart showing an example of the operation of the control system 12 according to embodiment 1.

In step S0, the group management device 14 determines whether the second communication unit 24 has received unique information and information on the accepted operation from any of the hall devices 13. If the determination result is No, the operation of the control system 12 proceeds again to step S0. If the determination result is Yes, the operation of the control system 12 proceeds to step S1.

In step S1, the group management device 14 determines whether the operation mode of the elevator 1 is the write mode. If the determination result is No, the operation of the control system 12 proceeds to step S2. If the determination result is Yes, the operation of the control system 12 proceeds to step S4.

In step S2, the allocation unit 25 reads the corresponding floor from the corresponding storage unit 23 using the unique information received by the second communication unit 24 as a key. After that, the operation of the control system 12 proceeds to step S3.

In step S3, the allocation unit 25 allocates the hall call, which has the floor read from the corresponding memory unit 23 as the departure floor, to one of the multiple units 4. The control panel 9 of the allocated unit 4 registers the hall call. After that, the operation of the control system 12 proceeds to step S0.

In step S4, the correspondence setting unit 29 judges whether the hall equipment 13 that transmitted the unique information belongs to the system selected by the system selection unit 28. If the judgment result is No, the operation of the control system 12 proceeds to step S0. Alternatively, if the judgment result is No, the operation of the control system 12 may proceed to step S2. In other words, when the hall equipment 13 that transmitted the unique information does not belong to the system selected by the system selection unit 28, the control system 12 may register a hall call by operating the hall equipment 13. On the other hand, if the judgment result is Yes, the operation of the control system 12 proceeds to step S5.

In step S5, the correspondence setting unit 29 determines whether the unique information received by the second communication unit 24 includes information indicating a special operation. If the determination result is No, the operation of the control system 12 proceeds to step S0. If the determination result is Yes, the operation of the control system 12 proceeds to step S6.

In step S6, the floor identification unit 26 identifies the floor on which the reference car is stopped. Then, the operation of the control system 12 proceeds to step S7.

In step S7, the correspondence setting unit 29 determines whether the unique information corresponding to the floor identified by the floor identification unit 26 is written in duplicate in the correspondence table T of the system to which the hall equipment 13 that transmitted the unique information belongs. If the determination result is No, the operation of the control system 12 proceeds to step S8. If the determination result is Yes, the operation of the control system 12 proceeds to step S9.

In step S8, the correspondence setting unit 29 writes the unique information in the correspondence table T for the system to which the hall equipment 13 that transmitted the unique information belongs, in association with the floor identified by the floor identification unit 26. After that, the operation of the control system 12 proceeds to step S0.

In step S9, the corresponding setting unit 29 notifies an alarm unit such as the buzzer 11 of the reference car that the writing has failed. After that, the operation of the control system 12 proceeds to step S0.

All hall equipment 13 of elevator 1 may belong to one system. Furthermore, the number of systems in elevator 1 does not have to match the number of units 4. The number of systems in elevator 1 may be one. Elevator 1 may be equipped with only one unit 4. In this case, elevator 1 does not need to have a group management device 14.

In addition, some or all of the control system 12, such as the mode switching unit 22, the corresponding memory unit 23, the second communication unit 24, the allocation unit 25, the floor identification unit 26, the car selection unit 27, the system selection unit 28, and the corresponding setting unit 29, may not be provided in the group management device 14. Some or all of these control systems 12 may be mounted on independent hardware. Some or all of these control systems 12 may be mounted on the control panel 9 of some or all of the units 4. In particular, when the elevator 1 does not have a group management device 14, some or all of these control systems 12 may be mounted on the control panel 9. In this case, each hall device 13 transmits unique information and information on the received operation to the control panel 9. Some or all of the functions of these control systems 12 may be realized by an external device such as a maintenance terminal connected to the elevator 1 when the floor setting work is performed.

When the elevator 1 does not have a group control device 14, the hall call is registered, for example, as follows. The control panel 9 reads out the corresponding floor from the correspondence memory unit 23 by referring to the correspondence table T using the unique information received by the second communication unit 24 as a key. The control panel 9 detects the floor and direction of the hall call based on the floor read out by the unique information and the information received by the second communication unit 24 together with the unique information. The control panel 9 registers the car 7 to respond to hall calls in the detected direction with the detected floor as the departure floor. In this way, the control panel 9 registers the car 7 to respond to hall calls with the floor corresponding to the unique information transmitted from the hall equipment 13 as the departure floor.

As described above, the control system 12 according to the first embodiment is applied to the elevator 1. The elevator 1 has one or more cars 7. Each car 7 travels between a plurality of floors. The control system 12 includes a plurality of hall equipment 13, a mode switching unit 22, a correspondence memory unit 23, a floor identification unit 26, and a correspondence setting unit 29. Each hall equipment 13 corresponds to one of the floors. Each hall equipment 13 is provided at the hall 3 of the corresponding floor. Each hall equipment 13 transmits unique information when an operation performed at the corresponding hall 3 is accepted. The unique information is information unique to each hall equipment 13. The mode switching unit 22 switches between a plurality of operation modes of the elevator 1, including a normal mode and a write mode. The correspondence memory unit 23 stores unique information of each of the hall equipment 13 in association with one of the floors so that when any of the hall equipment 13 receives an operation to register a hall call in the normal mode, the departure floor of the hall call can be identified. In the write mode, the floor identification unit 26 identifies the floor at which the reference car is stopped from among the multiple floors. The reference car is one or more of the cars 7. In the write mode, when unique information of any of the hall equipment 13 is transmitted from the hall equipment 13, the correspondence setting unit 29 stores the unique information in the correspondence memory unit 23 in association with the floor identified by the floor identification unit 26.
Moreover, the floor setting method for the elevator 1 according to the first embodiment is a floor setting method in the control system 12. The floor setting method includes a switching step, a receiving step, a floor specifying step, and a corresponding setting step. The switching step is a step of switching the operation mode from the normal mode to the write mode. The receiving step is a step of receiving, in the write mode, unique information of any one of the hall equipment 13 from the hall equipment 13. The floor specifying step is a step of specifying the floor where the reference car is stopped from among the multiple floors after receiving the unique information in the receiving step. The corresponding setting step is a step of storing the unique information received in the receiving step in the corresponding memory unit 23 in association with the floor specified in the floor specifying step.

With this configuration, the matching operation of the hall equipment 13 can be performed in any order during the floor setting work. This allows for greater flexibility in the floor setting work process. For example, the matching work for some floors can be postponed depending on the relationship with other work performed in parallel with the floor setting work. In addition, since the matching operation does not necessarily have to be performed in floor order, for example, mistakes in the order of operation when there is a break in between are suppressed. In addition, in response to a malfunction, etc., only some of the hall equipment 13 may be updated to new hall equipment 13. Alternatively, in response to a malfunction, etc., the hall equipment 13 of one set of floors among the multiple floors may be replaced with each other. Even in such a case, there is no need to perform matching work for the hall equipment 13 other than the updated or replaced hall equipment 13. This further improves the workability of the floor setting work. In addition, since the matching in the floor setting work is performed by operating the operation buttons 17 of the hall equipment 13, there is no need for the complicated work of removing the face plate 15 to expose the hall board 18. This further improves the workability of the floor setting work.

In addition, when each hall equipment 13 receives a special operation different from the operation for registering a hall call, it transmits information indicating the special operation together with the unique information. When the unique information of any hall equipment 13 transmitted from that hall equipment 13 is accompanied by information indicating a special operation, the correspondence setting unit 29 associates the unique information with the floor identified by the floor identification unit 26 and stores it in the correspondence storage unit 23. On the other hand, when the unique information of any hall equipment 13 transmitted from that hall equipment 13 is not accompanied by information indicating a special operation, the correspondence setting unit 29 does not store the unique information in the correspondence storage unit 23.

This configuration distinguishes between normal operations when registering hall calls and special operations when associating, reducing the occurrence of erroneous settings caused by erroneous operation of hall equipment 13 at a floor where the reference car is not stopped during floor setting work.

In addition, when the correspondence memory unit 23 already stores unique information that is the same as the unique information transmitted from any of the hall equipment 13, the correspondence setting unit 29 overwrites and stores the unique information in the correspondence memory unit 23 in association with the floor identified by the floor identification unit 26.

With this configuration, the floor to which each piece of unique information corresponds is uniquely stored in the correspondence storage unit 23. This prevents an incorrect departure floor from being set when registering a hall call. Even if an incorrect correspondence is stored due to a setting error, it becomes easy to correct the correspondence. Even when replacing hall equipment 13, it becomes easy to re-establish the correspondence after the replacement.

The control system 12 also includes an alarm unit. The alarm unit issues an alarm. Each hall equipment 13 belongs to one or more systems. The correspondence memory unit 23 may already store unique information that is different from the unique information transmitted from one of the hall equipment 13 and that belongs to the same system as the unique information and corresponds to the floor identified by the floor identification unit 26. In this case, the correspondence setting unit 29 causes the alarm unit to issue an alarm without storing the unique information transmitted from the hall equipment 13 in the correspondence memory unit 23.

With this configuration, the correspondence memory unit 23 uniquely stores the specific information corresponding to each floor. This prevents the wrong departure floor from being set when registering a hall call. In addition, the notification unit notifies the worker so that the worker can quickly confirm that the correspondence has failed.

The control system 12 also includes a system selection unit 28. The system selection unit 28 accepts an operation to select a set system to be set from among a plurality of systems. When the hall equipment 13 that transmitted the unique information belongs to the set system selected by the system selection unit 28, the correspondence setting unit 29 stores the unique information in the correspondence storage unit 23 in association with the floor identified by the floor identification unit 26. On the other hand, when the hall equipment 13 that transmitted the unique information does not belong to the set system selected by the system selection unit 28, the correspondence setting unit 29 does not store the unique information in the correspondence storage unit 23.

With this configuration, it is possible to select whether or not each system is to be subject to floor setting work. Therefore, when there are multiple systems, only some of the systems can be subject to floor setting work. At this time, hall equipment 13 belonging to systems that are not subject to floor setting work may accept operations to register hall calls. In this case, it becomes possible to perform floor setting work while transporting users of elevator 1. Therefore, convenience for users is unlikely to decrease.

The control system 12 also includes a car selection unit 27. The car selection unit 27 accepts an operation to select a reference car from one or more cars 7.

This configuration allows floor setting work to be performed using a reference car that is selected depending on the relationship with other work being performed in parallel with the floor setting work or the operating status of elevator 1, etc.
