Embodiment 1 FIG.
1 is a block diagram showing an elevator system according to Embodiment 1 of the present invention. The elevator system shown in FIG. 1 has a function of performing group management control on a plurality of elevators installed in the same building. The elevator system is configured so that an elevator user can register his / her destination floor (destination call) before boarding. 2 is a diagram showing an elevator hall in Embodiment 1 of the present invention, and FIG. 3 is an enlarged view of a portion C in FIG.

In the present application, a person who needs a larger space in the car than a general user when using an elevator such as a wheelchair user is called a specific user. In addition to the wheelchair user and the handicapped person, the specific user includes, for example, a person using a stroller or a carriage. In the following embodiments, a specific user will be described as a wheelchair user, in particular, for the sake of simplicity of explanation and easy understanding. However, specific users are not limited to wheelchair users.

1 to 3, a landing destination floor registration device 1 and a wheelchair landing call registration device 2 are installed in the elevator hall. The landing destination floor registration device 1 has a function for an elevator user to register his / her destination floor before boarding. In other words, the destination call is registered when the user performs a predetermined operation on the landing destination floor registration device 1 before boarding. When the destination call is registered, the landing destination floor registration device 1 transmits an allocation request for allocating a car to the registered destination call to the group management control device 3 described later. The landing destination floor registration device 1 also has a function of notifying a nearby user of a car assigned in response to an assignment request (hereinafter also referred to as “assigned car”).

Specifically, the landing destination floor registration device 1 shown in FIG. 3 includes a destination button 4 and a display 5. A plurality of destination buttons 4 are provided corresponding to each destination floor where the elevator can serve so that a destination call corresponding to each destination floor can be registered at the landing. For example, when the user wants to move to the fifth floor, a desired destination call can be registered by pressing the destination button 4 with “5” written on the button surface.

The display 5 is provided corresponding to each destination button 4 and displays an assigned car when the corresponding destination button 4 is operated. In the example shown in FIG. 3, “A” is displayed on the display 5 next to the destination button 4 indicating the fifth floor. This indicates that the car of No. A is assigned to the destination call registered when the destination button 4 indicating the fifth floor is pressed.

The wheelchair hall call registration device 2 is provided separately from the landing destination floor registration device 1 in the same hall so that wheelchair users can register a hall call before boarding. That is, a hall call is registered by a user (particularly, a wheelchair user) performing a predetermined operation on the wheelchair hall call registration device 2 before boarding. When the hall call is registered, the wheelchair hall call registration device 2 transmits an allocation request for allocating a car to the registered hall call to the group management control device 3. In addition, when a user registers a hall call with the wheelchair hall call registration device 2 and calls a car to the hall, the user operates his / her destination floor (by operating the operation panel in the car). Register the destination call).

Specifically, the wheelchair hall call registration device 2 shown in FIG. 3 includes a sign 6 indicating that a wheelchair user can operate, an UP button 7 for registering an UP direction hall call, and a DOWN direction hall. A DN button 8 for registering a call is provided.

The group management control device 3 is a device for group management control of a plurality of elevators installed in the same building. The group management control device 3 includes, for example, a car assignment unit 9, a destination call registration number limit unit 10, and a destination call registration number determination unit 11.

The car allocating unit 9 has a function of allocating a car in response to an allocation request from the landing destination floor registration device 1 based on the operation status of each elevator when the destination call is registered by the landing destination floor registration device 1. Have. Then, when the car assignment unit 9 assigns the car to the assignment request, the car assignment unit 9 transmits a destination call assignment instruction to each corresponding vehicle control device 12. In addition, the car allocating unit 9 transmits an allocation car notification to the landing destination floor registration device 1 simultaneously with the transmission of the allocation command to each of the vehicle control devices 12.

On the other hand, the car allocating unit 9 responds to the allocation request from the wheelchair landing call registration device 2 based on the operation status of each elevator when the landing call is registered by the wheelchair landing call registration device 2. Also has a function of assigning. Then, when the car assignment unit 9 assigns the car to the assignment request, the car assignment unit 9 transmits a landing call assignment instruction to each corresponding vehicle control device 12.

Each of the vehicle control devices 12 controls the operation of each elevator. That is, each vehicle control device 12 appropriately controls each elevator based on the allocation command received from the car allocation unit 9.
Further, the landing destination floor registration device 1 appropriately controls the display of the indicator 5 based on the notification of the assigned car received from the car assigning unit 9.

The destination call registration number limiting unit 10, when a car is assigned to the hall call registered by the wheelchair hall call registration device 2, determines the number of destination calls that can be registered in the assigned car. It has a function of limiting the number to a value that is less than the number that can be registered in normal time. For example, in the case of a 16-seater elevator in which the number of destination calls that can be registered at normal time is 8, if the elevator (car) is assigned in response to the assignment request from the wheelchair hall call registration device 2, the destination The call registration number limit unit 10 sets the number of destination calls that can be registered in the elevator to four.

Here, in the normal time, the hall call is not registered by the wheelchair hall call registration device 2, and all the destination calls assigned to the elevator (car) are registered by the hall destination floor registration device 1. The time when it was done. In addition, the “number of destination calls that can be registered at normal time” includes, for example, a case where a predetermined value is not set (when no upper limit is set for the number of destination calls that can be registered).

The destination call registration number determination unit 11 has a function of comparing the number of destination calls registered in each elevator with the number that can be registered to determine whether or not the number of registered destination calls is normal. . For example, if the registered number of destination calls for a car is set to a predetermined limit by the destination call registration number limit unit 10, the destination call registration number determination unit 11 counts the number of destination calls registered in this car. Is assigned to the registered destination call so that the car does not exceed the limit value.

Next, the specific operation of the elevator system having the above configuration will be described with reference to FIG. FIG. 4 is a flowchart showing the operation of the elevator system according to Embodiment 1 of the present invention.

The group management control device 3 always determines whether or not there is an allocation request from the landing destination floor registration device 1 and the wheelchair landing call registration device 2. When the hall call registration is performed by operating the wheelchair hall call registration device 2 at a certain hall (S101), the group management control device 3 causes the car assignment unit 9 to respond to the registered hall call. Then, an optimal car is selected and assigned (S102). In the following description, a car assigned in response to an assignment request from the wheelchair hall call registration device 2 (a car assigned to a wheelchair user's destination call) is referred to as a wheelchair assigned car.

In the group management control device 3, when the wheelchair assigned car is set in S102, the number of destination calls that can be registered in the wheelchair assigned car by the destination call registration number limiting unit 10 is determined from the number that can be registered in the normal time. Is also set to a reduced value (S103). Then, after limiting the number of registered destination calls in S103, the group management control device 3 is installed at each landing until the wheelchair assigned car arrives at the registration floor in response to the landing call registered in S101. It is determined whether or not there is an allocation request from the landing destination floor registration device 1 (S104 and S105).

As described above, when a destination call is registered by any one of the landing destination floor registration devices 1, the car assignment unit 9 assigns an appropriate car to the destination call. If the destination call is registered by the landing destination floor registration device 1 before the wheelchair assigned car arrives at the registration floor in response to the landing call registered in S101, the group management control device 3 is registered first. It is determined whether the destination call is assigned to the wheelchair assigned car (S106).

When the destination call is assigned to the wheelchair assigned car, the group management control device 3 determines the registered number of destination calls for the wheelchair assigned car by the destination call registered number judging unit 11. Specifically, the destination call registration number determination unit 11 compares the number of destination calls currently registered in the wheelchair assigned car with the predetermined limit value set in S103, and the current registration number is the above limit. It is determined whether or not the value has been exceeded (S107). When the registered number of current destination calls in the wheelchair assigned car exceeds the limit value, the group management control device 3 causes the car assignment unit 9 to reassign the destination calls registered in S104 ( S108). If it is determined in S107 that the current number of registered destination calls does not exceed the above limit value, the destination call registered in S104 is directly assigned to the wheelchair assigned car.

When the wheelchair assigned car arrives at the registration floor in response to the hall call registered in S101, the wheelchair user gets on the car and operates the operation panel in the car to register his destination floor (S109). ). When the destination call is registered in S109, the wheelchair assigned car travels in response to the registered destination call, and after arriving at the registered destination floor, opens and closes the door to get off the wheelchair user.

When the operation performed in relation to the hall call registered in S101 is completed, the destination call registration number restriction unit 10 releases the restriction on the registration number of destination calls set for the wheelchair assigned car in S103 (S110). And S111). That is, when the destination call registered in the car by the wheelchair user is canceled due to the arrival of the car, the destination call registration number limit unit 10 is the car to which the destination call is assigned (the car that was the wheelchair assigned car). The number of destination calls that can be registered in is returned to the normal value before the limit.

According to Embodiment 1 of the present invention, even if a wheelchair user uses an elevator, congestion in the car can be prevented, and the wheelchair user can get on and off with a margin. Will be able to. That is, when a wheelchair user registers a hall call with the wheelchair hall call registration device 2, the number of destination calls that can be registered in the car to which the hall call is assigned is smaller than usual. Is set. For this reason, even when the elevators are crowded, such as when commuting, the number of passengers in the car used by wheelchair users can be reduced compared to normal times. On the other hand, a comfortable service can be provided.

In the first embodiment, a case will be described in which the call registration device installed at the landing separately from the landing destination floor registration device 1 is a wheelchair landing call registration device 2 having an UP button 7 and a DN button 8. did. However, this call registration device may be any type such as a button type or a touch panel type as long as the wheelchair user can register the hall call before boarding. The call registration device may have a function of registering a destination floor (destination call) at a landing. In such a case, the operation of S109 in FIG. 4 becomes unnecessary.
In addition, the specific example is demonstrated in the following embodiment about the call registration apparatus provided with the function in which a wheelchair user can register a destination floor before boarding.

Embodiment 2. FIG.
5 is a block diagram showing an elevator system according to Embodiment 2 of the present invention, FIG. 6 is a diagram showing an elevator hall according to Embodiment 2 of the present invention, and FIG. 7 is an enlarged view of a portion D in FIG.

5 to 7, a landing destination floor registration device 1 and a wheelchair landing destination floor registration device 13 are installed in the elevator hall. The wheelchair landing destination floor registration device 13 is provided separately from the landing destination floor registration device 1 in the same hall so that a wheelchair user can register his / her destination floor before boarding. That is, a destination call is registered by a user (in particular, a wheelchair user) performing a predetermined operation on the wheelchair landing destination floor registration device 13 before boarding. When the destination call is registered, the wheelchair landing destination floor registration device 13 transmits an allocation request for allocating a car to the registered destination call to the group management control device 3. The wheelchair landing destination floor registration device 13 also has a function of notifying a nearby user of a car assigned in response to an assignment request.

Specifically, the wheelchair landing destination floor registration device 13 shown in FIG. 7 includes a sign 14, a destination button 15, and a display 16. In addition, since the function is the same as the landing destination floor registration apparatus 1, detailed description is abbreviate | omitted.

In addition, when the destination call is registered by the wheelchair landing destination floor registration device 13, the car assignment unit 9 of the group management control device 3 uses the wheelchair landing destination floor registration device 13 based on the driving situation of each elevator. Has a function of allocating a car in response to an allocation request from. Then, when the car assignment unit 9 assigns the car to the assignment request, the car assignment unit 9 transmits a destination call assignment instruction to each corresponding vehicle control device 12. Further, the car allocating unit 9 transmits a notification of the allocated car to the wheelchair landing destination floor registration device 13 simultaneously with the transmission of the allocation command to each of the vehicle control devices 12.

The destination call registration number limit unit 10, when a car is assigned to a destination call registered by the wheelchair landing destination floor registration device 13, determines the number of destination calls that can be registered in the assigned car. , It has a function of limiting to a value reduced from the number that can be registered in normal time.

By installing the wheelchair landing destination floor registration device 13, unlike the case of the first embodiment, the wheelchair user can also register the destination floor (the destination floor desired by the user). . For this reason, the section where the number of registered destination calls is limited by the destination call registration number limiting unit 10 is used by the wheelchair user (the person who registered the destination call using the wheelchair landing destination floor registration device 13). In consideration of the above, it is also possible to limit to a part of the section.

For example, when a car is assigned to a destination call registered by the wheelchair landing destination floor registration device 13, the destination call registration number limit unit 10 responds to the registered destination call from the current car position. The registered number of destination calls for the car is limited only for the section up to the floor just before the floor. In such a case, even when the destination floor is registered by the wheelchair landing destination floor registration device 13, the number of registered destination calls is kept at the normal value in the section not corresponding to the section.
Others have the same configuration as in the first embodiment.

Next, a specific operation of the elevator system having the above configuration will be described with reference to FIG. FIG. 8 is a flowchart showing the operation of the elevator system according to Embodiment 2 of the present invention.

In the group management control device 3, the presence / absence of an allocation request from the landing destination floor registration device 1 and the wheelchair landing destination floor registration device 13 is always determined. When a destination call is registered by operating the wheelchair landing destination floor registration device 13 at a certain landing (S201), the group management control device 3 uses the car assignment unit 9 to respond to the registered destination call. The optimal car is selected and assigned (S202).

In the group management control device 3, when the wheelchair assigned car is set in S202, the destination call registration number limiting unit 10 limits the number of destination calls that can be registered in the wheelchair assigned car to a certain section. Then, it is set to a value that is smaller than the number that can be registered in the normal time (S203 to S207). Specifically, the destination call registration number limit unit 10 only applies to the wheelchair assigned car from the current car position to the floor just before the floor corresponding to the destination call registered in S201. Limit the number of registered items.

That is, first, in S204, whether or not the landing on the predetermined floor corresponds to the section from the current position of the wheelchair assigned car to the floor immediately before the floor corresponding to the destination call registered in S201. Is determined. Then, for the landing on the floor that is determined to be applicable in the determination of S204, the number of destination calls that can be registered in the wheelchair assigned car is set to a predetermined limit value that is smaller than normal (S205). On the other hand, for the landing at the floor that is determined not to be applicable in the determination of S204, the number of destination calls that can be registered in the wheelchair assigned car is set to the normal value (S206).

After performing the operations shown in S204 to S206 for all floor landings (S203 and S207), the group management control device 3 arrives at the registered floor in response to the destination call registered in S201 for the wheelchair assigned car. Until this is done, it is determined whether or not there is an allocation request from the landing destination floor registration device 1 installed at each landing (S208 and S209).

If the destination call is registered by the landing destination floor registration device 1 before the wheelchair assigned car arrives at the registration floor of the destination call registered in S201, the group management control device 3 indicates that the registered destination call is wheelchair assigned. If it is determined whether the car is assigned (S210), and if it is determined in S210 that the car is assigned, the registered number of destination calls for the wheelchair assigned car is further determined (S211). In S211, if the number of destination calls registered in the wheelchair assigned car exceeds the limit value set for the corresponding floor, the group management control device 3 sends a call to the car assigning unit 9. On the other hand, the destination call registered in S208 is reassigned (S212).

If the wheelchair assigned car has not arrived at the registration floor of the destination call registered in S201 in S209, the process returns to S203, and the operations from S203 to S212 are repeated. Therefore, the number of destination calls that can be registered changes in each floor as the wheelchair assigned car travels (moves). For example, the number of destination calls that can be registered for floors to which a wheelchair assigned car passes before reaching the registration floor of the destination call registered in S201 and the wheelchair assigned car moves away thereafter. Is set to the above limit value until the wheelchair assigned car passes, and is set to a normal value after the wheelchair assigned car passes.

The destination call by the wheelchair user has already been registered in S201. For this reason, after the wheelchair assigned car arrives at the registration floor of this destination call, the door is opened and closed to allow the wheelchair user to get on and travel to the target floor (S213). The group management control device 3 performs the same operation as S203 to S207 until it reaches the destination floor registered by the wheelchair user (S214 to S218), and resets the number of destination calls that can be registered. Perform every time.
Other operations are the same as those in the first embodiment.

According to the second embodiment of the present invention, it is possible to minimize the section that restricts destination calls that can be registered. For this reason, it is possible to prevent a decrease in the transportation capacity of the elevator and to provide a comfortable service to the user. Other effects are the same as those of the first embodiment.

In the second embodiment, the case where the destination floor registration device for wheelchairs is installed at the landing separately from the general ones has been described. However, the landing destination floor registration device 1 and the wheelchair landing destination floor registration device 13 are only required to be provided separately at least functionally. For example, a wheelchair button is provided in the landing destination floor registration device 1. You may comprise so that operation of the destination button 4 after this button for wheelchairs may be recognized as operation with respect to the said wheelchair landing destination floor registration apparatus 13. FIG. In this way, if a general and wheelchair-use destination floor registration device is installed at the landing, the system configuration can be simplified.

Embodiment 3 FIG.
9 is a block diagram showing an elevator system according to Embodiment 3 of the present invention, FIG. 10 is a diagram showing an elevator hall according to Embodiment 3 of the present invention, and FIG. 11 is an enlarged view of a portion E in FIG.

9 to 11, a hall destination floor registration device 1 and a personal authentication device (personal authentication unit) 17 are installed in the elevator hall. The personal authentication device 17 has a function of identifying and authenticating a registered individual based on biometric information such as a fingerprint and input information such as a password and a card. That is, in the personal authentication device 17, wheelchair users and general users who use this elevator are registered in advance. Therefore, when a general user or a wheelchair user inputs predetermined information, the authenticator is identified as a specific general user or a wheelchair user.

When the personal authentication device 17 identifies a predetermined individual from the input information, the personal authentication device 17 transmits registration information preset for the individual to the landing destination floor registration device 1. This registration information includes, for example, a wheelchair attribute indicating that the user is a wheelchair user, a general attribute indicating that the user is a general user, and a destination floor.

Upon receiving registration information from the personal authentication device 17, the landing destination floor registration device 1 automatically registers a destination call corresponding to the registration information, and the group management control device 3 responds to the registered destination call. Send an assignment request to assign a car. The landing destination floor registration device 1 receives a wheelchair attribute registration information from the personal authentication device 17, and distinguishes a specific (wheelchair attribute) assignment request from the assignment request for the general attribute destination call. It transmits to the management control device 3.
Accordingly, the personal identification device 17 and the function of the landing destination floor registration device 1 when the wheelchair attribute registration information is received from the personal authentication device 17 constitute a wheelchair destination floor registration device.
Others have the same configuration as in the first or second embodiment.

Next, the specific operation of the elevator system having the above configuration will be described with reference to FIG. FIG. 12 is a flowchart showing the operation of the elevator system according to Embodiment 3 of the present invention.

In the group management control device 3, the presence / absence of an allocation request from the landing destination floor registration device 1 is always determined. Then, when the wheelchair user operates the personal authentication device 17 at a certain landing and the landing destination floor registration device 1 receives the wheelchair attribute registration information (S301), the landing destination floor registration device 1 includes the registration information. Based on this, the destination call of the wheelchair attribute is automatically registered. Then, the group management control device 3 selects and assigns the optimum car to the registered destination call by the car assignment unit 9 (S302).

In the group management control device 3, when the wheelchair assigned car is set in S102, the destination call registration number restriction unit 10 sets the number of destination calls that can be registered to the wheelchair assigned car to a predetermined limit value that is smaller than usual. (S303). Then, after limiting the registered number of destination calls in S303, the group management control device 3 determines whether the wheelchair assigned car is installed at each landing floor until it reaches the registration floor in response to the wheelchair attribute destination call. The presence / absence of a general attribute assignment request from the registration apparatus 1 is determined (S304 and S305).

When the wheelchair-assigned car arrives at the wheelchair-attributed destination call registration floor and the personal authentication device 17 is operated to register the general-attribute destination call, the group management control device 3 displays the car-assignment unit 9 Therefore, after allocating the car to this destination call (S306), if it is determined whether the general attribute destination call is allocated to the wheelchair allocated car (S307) and if it is determined in S307 that it is allocated Further, the registered number of destination calls for the wheelchair assigned car is determined (S308). In S308, when the number of destination calls registered in the wheelchair assigned car exceeds the limit value set in S303, the group management device 3 is registered with the car assigning unit 9 in S306. The destination call is reassigned (S309).

When the wheelchair assigned car arrives at the registration floor in response to the wheelchair-designated destination call, the wheelchair assigned car door is opened and closed, and the wheelchair user is picked up. The wheelchair assigned car travels in response to the registered destination call of the wheelchair attribute, and after arriving at the registered destination floor, opens and closes the door and gets the wheelchair user off.

When the above operation performed in relation to the wheelchair attribute destination call registered in S302 ends, the destination call registration number limit unit 10 sets the limit on the number of destination call registrations set for the wheelchair assigned car in S303. Release (S310 and S311). That is, when the destination call having the wheelchair attribute is canceled due to arrival of the car, the destination call registration number limiting unit 10 can register the destination call that can be registered in the car to which the destination call is assigned (the car that has been assigned to the wheelchair). Return the number of calls to the normal value before the limit.
Other operations are the same as those in the first or second embodiment.

According to the third embodiment of the present invention, when registering a destination call, a user (especially a wheelchair user) can be specified by the personal authentication device 17, and a general user can register a destination call with a wheelchair attribute. Can be prevented. For this reason, the number of registered destination calls is not limited except when the wheelchair user uses the elevator, and a decrease in operation efficiency can be reliably prevented. In addition, since the individual identification and registration of the individual destination call are performed by a predetermined operation on the personal authentication device 17, the operation required for the wheelchair user or the like can be reduced and the operability can be improved. . It is also possible to simplify the device installed at the landing.
Other effects are the same as those of the first or second embodiment.

In the third embodiment, the case where the general user also uses the personal authentication device 17 has been described. However, as usual, the general user directly operates the landing destination floor registration device 1 to display his / her destination floor. You may comprise so that it may register.

Further, the personal authentication device 17 may be used instead of the wheelchair button mentioned in the second embodiment. In such a case, the user directly operates the landing destination floor registration device 1 to register his / her destination floor. The landing destination floor registration device 1 receives the wheelchair attribute registration information (information related to the destination call) from the personal authentication device 17. The wheelchair attribute assignment request is transmitted to the group management control device 3 only for the operation of the destination button 4 immediately after receiving the command.

Embodiment 4 FIG.
Since the configuration of the elevator system in this embodiment is the same as that shown in FIG. 1, its detailed description is omitted. However, when a car is assigned to the hall call registered by the wheelchair hall call registration device 2, the destination call registration number limit unit 10 is the actual number of destination calls registered in the wheelchair assigned car. By multiplying the number by the increase factor that increases the number in the aggregate, the number of pretending destination calls is increased, and the number of destination calls that can be registered in the wheelchair assigned car is larger than the number that can be registered in normal times. Limit to reduced values. Therefore, in the determination by the destination call registration number determination unit 11, the registerable number compared with the number of destination calls registered in the elevator is always a constant value.

Next, the specific operation of the elevator system having the above configuration will be described with reference to FIG. FIG. 13 is a flowchart showing the operation of the elevator system according to Embodiment 4 of the present invention.

When a hall call is registered by operating the wheelchair hall call registration device 2 at a certain hall (S401), the group management control device 3 uses the car assignment unit 9 to optimize the registered hall call. A basket is selected and assigned (S402). After setting the wheelchair assigned car, the group management control device 3 registers the landing destination floor installed at each hall until the wheelchair assigned car arrives at the registration floor in response to the hall call registered in S401. The presence / absence of an allocation request from the apparatus 1 is determined (S403 and S404).

If the destination call is registered by the landing destination floor registration device 1 before the wheelchair assigned car arrives at the registration floor in response to the above hall call, the group management control device 3 causes the registered destination call to be assigned to the wheelchair. It is determined whether or not the car is assigned (S405).

When the destination call is assigned to the wheelchair assigned car, the group management control device 3 first performs an operation of counting the number of destination calls registered in the wheelchair assigned car. Specifically, the actual number of destination calls registered in the wheelchair assigned car is multiplied by an increase factor for increasing the total number of destination calls, thereby increasing the registered number of destination calls in the apparent wheelchair assigned car (S406). . Then, as a result of the determination by the destination call registration number determination unit 11, when the registered number of destination calls counted in S 406 exceeds a predetermined registration limit value, the car call allocation unit 9 is registered in S 403. Reassign destination calls (S407 and S408).

The operation after the wheelchair assigned car arrives at the registration floor in response to the hall call registered in S401 is the same as the operation shown in S109 and thereafter in FIG.

According to the fourth embodiment of the present invention, by multiplying the actual number of destination calls registered in the wheelchair assigned car by an increase factor that increases the total number in the total, the same as the elevator system in the first embodiment. Function can be realized.
Needless to say, the above functions can also be applied to the second and third embodiments.

In addition, when the personal authentication device 17 is installed at the hall as in the third embodiment, the registration information from the personal authentication device 17 includes the increase coefficient that is different for each individual. It is also possible to calculate the total value according to the required car space for each user.

As described above, the elevator system according to the present invention is applicable to a system in which group management control is performed and a call registration device for a general user and a specific user is provided in the elevator hall. is there.
