Description

The embodiments of the present invention relate to an elevator group management control device and an elevator group management control method.

Conventionally, elevators may be equipped with a reopening function for the operation of the car door of the car. The reopening function means that when a passenger at the relevant landing performs a hall call registration operation while the door of the elevator car that opened in response to the hall call is being closed, the door of the relevant car will be closed. is the function to reverse and open the door again. By installing this reopening function, the elevator can be operated efficiently by allowing as many users as possible to get into the car in one run.

Depending on the request of the building manager, etc., this reopening function may be disabled in order to give priority to the convenience of users who have already boarded the car. If the reopening function is disabled, even if a user at the boarding point performs the boarding hall call registration operation while the car that opened at the boarding point in response to the hall call is closing the door, the car does not reopen.

<Configuration of elevator system using group supervisory control device according to one embodiment>
A configuration of an elevator system according to one embodiment of the present invention will be described with reference to FIG. The elevator system 1 according to the present embodiment includes a plurality of elevators (A-car elevator 10A, B-car elevator 10B, and C-car elevator 10C) installed in the building, hall call registration devices 20 and 30 installed in the hall. and a group supervisory control device 40 . The call registration devices 20 and 30 are installed in the halls of each floor, but FIG. 1 shows only the first floor as the elevator hall.

The A-car elevator 10A has a car 11A and an A-car controller 12A. The car 11A has a car door 111A. The A car control device 12A has an elevator information output section 121A and an operation control section 122A. The elevator information output unit 121A outputs the position information of the car 11A, the traveling status information, the door opening/closing status information, the load status information, etc. to the group supervisory control device 40 as elevator information. The operation control unit 122A responds to the assignment command from the group supervisory control device 40 so that the A elevator 10A responds to the registered floor of the call and opens the door.

Since the B elevator 10B and the C elevator 10C have the same configuration as the A elevator 10A, detailed description thereof will be omitted.

The hall call registration devices 20 and 30 are used by hall users to register hall calls for calling one of the cars 11A to 11C by designating the direction of the destination floor.

The group management control device 40 group-manages the A-car elevator 10A, the B-car elevator 10B, and the C-car elevator 10C. The group supervisory control device 40 has an elevator information acquisition section 41 , a reopening function setting section 42 , a hall call registration section 43 , an allocation control section 44 and an allocation information output section 45 .

The elevator information acquisition unit 41 acquires elevator information output from each of the control devices 12A to 12C.

The reopening function setting unit 42 sets enable/disable of the reopening function for the elevators 10A to 10C. The reopening function is to reopen the elevator car when a hall call is registered at the relevant floor when the door of the elevator car is closed on the corresponding floor in response to the hall call. It is a function to open

The hall call registration unit 43 receives and registers the hall call information acquired from the hall call registration devices 20 and 30 . The allocation control unit 44 evaluates each of the elevators 10A to 10C from the information of the hall call registered in the hall call registration unit 43 and the elevator information acquired from each of the control devices 12A to 12C, and selects the optimum number of elevators to which the hall call is assigned. decide.

The assignment information output unit 45 outputs an assignment command to the corresponding elevator based on the assigned car information determined by the call assignment control unit 44 .

<Operation of Elevator System According to One Embodiment>
Next, the operation of the elevator system 1 according to this embodiment will be described. First, with reference to FIG. 2, the operation executed by the group supervisory control device 40 when a hall call is registered at a predetermined floor while the door of one of the elevator cars is being closed at the hall of the predetermined floor. explain. Although the hall call registration device 20 will be used to register hall hall calls, the hall call registration device 30 may be used.

When the reopening function setting unit 42 of the group supervisory control device 40 has enabled the reopening function ("YES" in S1), the first-floor hall call registering device 20 indicates that the user a is in an upward hall. When a call operation is performed, the information of the hall call made by the operation is registered in the hall call registration unit 43 .

Then, the allocation control unit 44 allocates one of the elevators, for example, the A elevator 10A, as the elevator that responds to the hall call. When the A elevator 10A is assigned by the assignment control unit 44, the assignment information output unit 45 outputs an assignment instruction of the hall call for the first floor to the A elevator control device 12A. The operation control unit 122A of the A-car control device 12A causes the car 11A to land on the first floor hall and open the door based on the allocation instruction acquired from the group supervisory control device 40 ("YES" in S2). When the door of the car 11A is opened, the user a gets into the car 11A.

After that, while the car door 111A of the car 11A is being closed, when another user b performs an upward hall call operation using the hall call registration device 20 on the first floor, the information of the hall call by the operation is displayed in the hall. It is registered in the call registration unit 43 ("YES" in S3). In response to the hall call registered here, the allocation control unit 44 determines to respond by reopening the car 11A whose doors are being closed (S4). When it is decided to reopen the car 11A, the allocation information output unit 45 outputs a reopening command to the A car control device 12A.

The operation control unit 122A of the A-car control device 12A reopens the car 11A based on the reopening command acquired from the group supervisory control device 40. FIG. The user b gets into the car 11A whose door has been opened again.

Further, when the reopening function is set to be valid ("YES" in S1), the user c moves to the first floor in the car of one of the elevators, for example, the car 11A of the elevator 10A of the A unit. When the car call operation is performed, the operation control unit 122A causes the car 11A to land on the first floor landing and open the door ("NO" in S2→"YES" in S5). When the door of the car 11A opens, the user c gets off from the car 11A.

After that, when another user d performs an upward hall call operation with the hall call registration device 20 on the first floor while the car door 111A of the car 11A is being closed, the information of the hall call by the operation is displayed at the hall. It is registered in the call registration unit 43 ("YES" in S6). For the hall call registered here, the allocation control unit 44 allocates the most suitable elevator, for example, the A-elevator 10A, from among all the elevators 10A to 10C, including the A-elevator 10A whose doors are being closed. It is determined as the car number (S7). As the optimum number, for example, an elevator having a car that arrives at the landing on the first floor the earliest is selected.

When the elevator car to be assigned to the first floor hall call is determined to be the A elevator car 10A, the allocation information output unit 45 outputs an allocation command to the A car control device 12A. The operation control unit 122A of the A-car control device 12A causes the car 11A to respond based on the allocation command acquired from the group supervisory control device 40. FIG. The operation of the car 11A at this time is the same operation as when the car 11A is reopened based on the information determined in step S4, that is, the car door 111A during the closing operation is reversed and opened. . The user d gets into the car 11A with the doors open.

Further, when the reopening function is set to be invalid ("NO" in S1), the elevator car 11A is opened by the user e performing an upward hall call operation on the hall call registration device 20 on the first floor. When the door is opened ("YES" in S8), the user e gets into the car 11A.

Thereafter, while the car 11A is in the door closing operation, when another user f performs an upward hall call operation with the hall call registration device 20 on the first floor ("YES" in S9), the allocation control unit 44 Without re-opening the car 11A, another elevator, for example, the B elevator 10B, is assigned to the hall call (S10).

When the assignment control unit 44 assigns the B elevator 10B, the assignment information output unit 45 outputs an instruction to assign the first floor hall call to the B elevator control device 12B. The operation control unit 122B of the B-car control device 12B causes the car 11B to land on the first-floor landing and open the door based on the allocation instruction acquired from the group control device 40 . When the door of the car 11B opens, the user f gets into the car 11B.

Further, when the reopening function is set to be disabled ("NO" in S1), the user g moves to the first floor in one of the elevator cars, for example, the car 11A of the elevator 10A of the A unit. When the car call operation is performed, the operation control unit 122A causes the car 11A to land on the first floor landing and open the door ("NO" in S8→"YES" in S11). When the door of the car 11A is opened, the user g gets off from the car 11A.

After that, while the door of the car 11A is being closed, when another user h performs an upward hall call operation on the hall call registration device 20 on the first floor, the hall call registration unit 43 receives the hall call information by the operation. ("YES" in S12). For the hall call registered here, the allocation control unit 44 executes one of the following allocation processes (1) to (3).

[Assignment process (1)]
Allocation processing (1) executed by the allocation control unit 44 will be described with reference to the flowchart of FIG. If there is a user in the car 11A whose door is open in step S11 ("YES" in S21), and if it is determined that there is another car number that can be assigned ("YES" in S22), the assignment control unit 44 performs step S12. Any elevator other than the A No. elevator 10A having the car 11A whose doors are being closed is assigned to the hall call registered in (S23). Whether or not there is a user in the car 11A is determined by information detected by a load detection device (not shown) installed in the car 11A, image information captured by an in-car camera device (not shown), Alternatively, it is determined based on the presence/absence of car call registration.

In step S22, when it is determined that there is no elevator that can be assigned at this stage ("NO" in S22), the assignment control unit 44 generates an elevator that can be assigned to the hall call based on the operating status of each elevator. The allocation process is temporarily suspended until ("NO" in S24). Then, when there is an elevator that can be assigned to the hall call ("YES" in S24), the elevator is assigned to the hall call (S25).

In step S21, if there is no user in the open car 11A ("NO" in S21, the allocation control unit 44 allocates the hall call to the car 11A whose doors are being closed (S26).

When the allocation control unit 44 executes the allocation process, the allocation information output unit 45 outputs an instruction to allocate the hall call for the first floor to the control device of the corresponding elevator. The operation control unit of the control device that has acquired the allocation instruction causes the corresponding car to land on the first-floor landing and open the door or reopen the door based on the allocation instruction. When the door of the car opens, the user h gets into the car.

[Assignment process (2)]
Allocation processing (2) executed by the allocation control unit 44 will be described with reference to the flowchart of FIG. Since the processes executed in steps S31 to S33 are the same as the processes in steps S21 to S23 described in allocation process (1), detailed description thereof will be omitted.

When it is determined in step S32 that there is no elevator that can be assigned at this stage, the assignment control unit 44 monitors whether or not the closing operation of the car 11A has been completed (S34). When the allocation control unit 44 detects that the door closing operation of the car 11A has been completed ("YES" in S34), the assignment control unit 44 selects the , and selects and assigns the optimum machine (S35).

In step S31, if there is no user in the open car 11A ("NO" in S31, the allocation control unit 44 allocates the hall call to the car 11A whose doors are being closed (S36).

When the allocation control unit 44 executes the allocation process, the allocation information output unit 45 outputs an instruction to allocate the hall call for the first floor to the control device of the corresponding elevator. The operation control unit of the control device that has acquired the allocation instruction causes the corresponding car to land on the first-floor landing and opens or reopens the door based on the allocation instruction. When the door of the car is opened, the user h gets into the car.

[Assignment process (3)]
Allocation processing (3) executed by the allocation control unit 44 will be described with reference to the flowchart of FIG. The processing executed in steps S41 to S43 is the same as the processing in steps S21 to S23 described in allocation processing (1), so detailed description thereof will be omitted.

In step S42, if it is determined that there is no elevator that can be assigned at this stage ("NO" in S42), for example, if the user h is a wheelchair user and the wheelchair-accessible elevator is only the A-elevator 10A , the allocation control unit 44 allocates the hall call to the A elevator 10A during the door closing operation.

At this time, the car 11A is reversed and opened while the door is being closed, so the operation is the same as when the reopening function is valid. When this operation is performed, the user who recognizes that the reopening function is disabled in the elevator system 1 will not be able to operate according to the setting and the reopening function will be disabled. Sometimes I feel as if I am In addition, by reopening the door just before departure, the user who got on first and the user who got on after the door was reopened may feel uncomfortable.

Therefore, when the car 11A is opened by allocating the A-equipment elevator 10A that is in the door closing operation, the notification information regarding the re-opening of the door, for example, the information notifying that the door has been re-opened due to the presence of a wheelchair user, The information is output from an output device such as a speaker device (not shown) in the car 11A. This makes it possible for the user in the car 11A to recognize the reason why the door has been opened again, and to avoid feeling embarrassed with the user who has boarded the car.

In step S41, if there is no user in the open car 11A ("NO" in S41, the allocation control unit 44 allocates the hall call to the car 11A whose doors are being closed (S45).

When the allocation control unit 44 executes the allocation process, the allocation information output unit 45 outputs an instruction to allocate the hall call for the first floor to the control device of the corresponding elevator. The operation control unit of the control device that has acquired the allocation instruction causes the corresponding car to land on the first-floor landing and opens or reopens the door based on the allocation instruction. When the door of the car is opened, the user h gets into the car.

According to the above-described embodiment, in an elevator in which the reopening function for a car opened in response to a hall call is set to be disabled, the doors of a car opened in response to a car call are also closed. The door can be controlled so as not to open again during operation.
