  First, the configuration of the group management control system according to the first embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing a group management control system according to the first embodiment of the present invention.

  In general, an elevator for a wheelchair user is usually one elevator car in one group management system. However, in recent years, an increasing number of cases where all elevator cars are also used as wheelchair users. Also in this embodiment, the description will be made on the assumption that all elevator cars are shared with wheelchair users.

  As shown in FIG. 1, the elevator group management control system according to the present embodiment uses a general hall call registration button 1an (n = 1, 2, 3,...) For a general user to make a hall call, wheelchair use. Wheelchair hall call registration button 1bn (n = 1, 2, 3,...)

Hereinafter, the configuration of the elevator group management control system according to the present embodiment will be described in detail.

  Each floor of the building hall is provided with a general hall call registration button 1an (n = 1, 2, 3,...) And a wheelchair hall call registration button 1bn (n = 1, 2, 3,...). In the present embodiment, hereinafter, the general hall call registration button 1an and the wheelchair hall call registration button 1bn are collectively referred to as a hall call device 1.

  A hall call detection unit 2 is connected to the hall call device 1, and the hall call detection unit 2 is connected to an allocation control unit 3. The hall call detection unit 2 receives a signal from the hall call device 1 and outputs the detected hall call registration information to the allocation control unit 3 when the occurrence of a new hall call is detected. The allocation control unit 3 that has received the hall call registration information is set to select an optimal car 11 to be allocated to the detected hall call. Details of selection of the optimum car by the allocation control unit 3 will be described later.

  The allocation control unit 3 is connected to a car state information acquisition unit 4, a predicted load calculation unit 6, a call registration status monitoring unit 7, and an allocation instruction unit 9.

  The allocation control unit 3 outputs an allocation signal to the single control unit 10 via the allocation instruction unit 9, and the single control unit 10 that has received the allocation signal is set to control the car 11 connected thereto. ing.

  In addition, a car state information acquisition unit 4 that acquires operation information of the car 11 is connected to the single control part 10 that controls each car 11. The operation information of the car 11 includes current position of the car 11, current traveling direction, current load, current speed, moving, door open, door closed, door open state, door closed state, stopped, resting, etc. Information is included. Acquisition of the operation information of the car 11 by the car state information acquisition unit 4 is set to be periodically performed, for example, at a cycle of 100 msec.

  The car 11 includes a general car call registration button 12a and a wheelchair car call registration button 12b.

  Further, the assignment control unit 3 is set so that the operation information of the car 11 can be periodically acquired from the car state information acquiring unit 4.

  The car call registration information acquisition unit 5 is connected to each single control unit 10 and is set to periodically acquire the single call control unit 10 car call registration information. At this time, the car call registration information is set so as to be acquired separately from the general car call registration information and the wheelchair car call registration information. A car call registration status monitoring unit 7 is connected to the car call registration information acquiring unit 5, and the car call registration status monitoring unit 7 is a general car of each car 11 acquired by the car call registration information acquiring unit 5. Call registration information and wheelchair car call registration information are monitored and maintained.

  The predicted load calculation unit 6 is connected to the car status information acquisition unit 4 and the car call registration status monitoring unit 7, and from the information obtained from the car status information acquisition unit 4 and the car call registration status monitoring unit 7, It is set to calculate the predicted load in the car at the time of departure from the floor.

  As described above, the elevator group management system according to the present embodiment is configured.

  Next, selection of the optimal car in consideration of the general hall call and the wheelchair hall call by the allocation control unit 3 will be described in detail. According to the present embodiment, the allocation control unit 3 selects the car that minimizes the unanswered time of the car 11 for the general hall call, and selects the car that considers the free space in the car 11 for the wheelchair hall call. I do. Further, in the present embodiment, allocation control considering a boarding space for wheelchair hall calls will be described. Hereinafter, in order to simplify the description, the number of elevators that are group-controlled is assumed to be two, and each of them will be described as Unit A and Unit B.

  Now, as a result of acquiring the state information of each car by the car state information acquisition unit 4, the state shown in FIG. 2 is obtained. That is, the current position of Unit A is 2F, the direction of travel is upward, the load in the car is 320 kg, and the current position of Unit B is 6F, the direction of travel is downward, the load in the car is 400 kg, and it is traveling is there. In FIG. 2, a black triangle indicates a general hall call, a white triangle indicates a wheelchair hall call, a black circle indicates a general car call, and a white circle indicates a wheelchair car call. The positions indicated are the call registration floor and the designated floor, and the direction of the triangle indicates the traveling direction.

  At this time, the car call registration status monitoring unit 7 stores the hall call assignment status and the car call occurrence status of No. A and No. B separately for general and wheelchairs. Specifically, in the situation as shown in FIG. 2, the call registration status of Unit A is the registration status as shown in FIG. 3, and the call registration status of Unit B is the registration status as shown in FIG. Yes. 3 and 4, “1” indicates call registration, and “0” indicates unregistered.

  Under the above situation, the optimal allocation process of the car 11 when the wheelchair landing call registration button 1b generates a downward wheelchair landing call will be described with reference to the flowchart of FIG.

  First, the predicted load calculation unit 6 predicts and calculates a load in the car when each unit departs from each floor, that is, a predicted load at departure (S1).

  Here, the predicted load calculation unit 6 that calculates the predicted load at the time of departure of each floor creates a predicted load table as shown in FIG. 6, and the departure when the car 11 is raised and lowered as shown in FIG. The hourly load is calculated. In FIG. 6, WUf represents a predicted load at the time of departure from the f-th floor direction, and WDf represents a predicted load at the time of departure from the f-th floor direction. In the present embodiment, there is no upward hall call on the top floor and no downward hall call on the bottom floor.

  Here, the calculation method of the predicted load at the time of departure of each floor by the predicted load calculation unit 6 will be described. First, the in-car loads of Unit A and Unit B at the current floor position are measured. As described above, the load in each car is 320 kg in the upward direction of 2F, and No. B is 400 kg in the downward direction of 6F. Although the measuring method of the load in a car here is not specifically limited, For example, a load shall be measured with the in-car load detection apparatus etc. which are provided in a car floor. In addition, among the car calls registered in each car, the predicted load at the time of departure at the endmost floor with respect to the traveling direction is set to 0 kg and set in the predicted load table.

  In the present embodiment, the description will be made assuming that the load of the general user is set to 60 kg and the load of the wheelchair user is set to 120 kg.

  Hereinafter, the calculation of the predicted load of each floor and the creation of the predicted load table in Unit A will be specifically described.

  First, as shown in FIG. 7, in the predicted load table, an initial value of 320 kg is set at 2F, which is the current position of Unit A. Next, the subtraction of the load of 60 kg as the unloading load is performed at 5F which is the general car call registration floor. Moreover, since it is a wheelchair car call generation floor in 6F, the load 120 kg which is a getting-off load is subtracted. At this time, since 6F is the car calling end floor of Unit A, the predicted load should be 0 kg on the 6th floor. Therefore, the predicted load calculation unit 6 performs a process of adding a correction value so that the load in the car at the 6th floor, which is the car floor endmost floor, becomes 0 kg. Specifically, the predicted load on the 6th floor before correction is (initial load of Unit A) − (5th floor unloading load + 6th floor unloading load), that is, 320 kg−180 kg = 140 kg remaining amount. Therefore, -140 kg is added as a correction value.

  Next, the boarding load by the response of the hall call generated on each floor is added. Here, as shown in FIG. 8, in order to respond to the general hall call in the upward direction on the third floor and the general hall call in the downward direction on the eighth floor, 60 kg as the boarding load is added at each floor.

  Next, the car call registered by the passenger boarded at the response of the hall call generated at each floor, that is, the getting-off load due to the derived car call is subtracted. In the present embodiment, it is assumed that the derived car call is generated on the top floor in the case of an upward landing call and on the bottom floor in the case of a downward landing call. In addition, as a derived car call, a derived car call generated by a general hall call is a general car call, and a derived car call generated by a wheelchair hall call is a wheelchair car call. Therefore, in the present embodiment, the derived car call of the general hall call in the upper direction of the third floor is assumed to be the top floor, the eighth floor being the highest floor, and the derived car call of the general hall call in the lower direction of the eighth floor is assumed to be the first floor being the lowest floor. The load calculation unit 6 calculates a predicted load. That is, a load of 60 kg, which is an unloading load, is subtracted at each of the 8th floor and the 1st floor where the derived car call is generated. Therefore, the relationship between the predicted loads of each floor is as shown in FIG.

  Through the above processing, the initial value of 320 kg is set at 2F, which is the current position of Unit A, and when the predicted load table is filled as shown in FIGS. 7 to 9, a predicted load table as shown in FIG. 10 is created. Is done. Thus, the predicted load of each floor can be obtained.

  Similar to the above-described method, when the predicted load is obtained for Unit B, a predicted load table as shown in FIG. 11 is created.

  Returning to the flowchart of FIG. 5, after step 1, the allocation control unit 3 uses the information obtained from the car call registration status monitoring unit 7 to register the wheelchair car call derived from the wheelchair car call and the wheelchair landing call. A floor section is obtained (S2).

  That is, in the case of Unit A as shown in FIG. 2, wheelchair car calls are registered on the sixth floor, and other wheelchair car calls, wheelchair landing calls, and derived wheelchair car calls are not registered. Therefore, the floor section where the wheelchair car call is registered in the A-unit is the upward traveling section from the second floor to the sixth floor which is the current position. That is, the wheelchair user is in the car 11 at the time of departure on the 2nd to 5th floors.

  Similarly, in Unit B, wheelchair landing calls are registered on the first floor, and wheelchair car calls are registered on the first floor. In the present embodiment, since the derived car call for the upward hall call is assumed to occur on the top floor, that is, the eighth floor, the floor section where the wheelchair car call is registered runs downward from the sixth floor to the first floor. It is a section and an upward traveling section from the first floor to the eighth floor. That is, the wheelchair user is in the car 11 at the time of departure from the 6th floor to the 2nd floor in the downward direction and at the time of departure from the 1st to 7th floors in the upward direction.

  In addition, although the section which has even one wheelchair car call was calculated here, the number of wheelchair car calls held is arbitrarily set according to the rated load capacity of the car, and the section that has reached that number is calculated. It is good.

  Next, the allocation control unit 3 determines from the information obtained from the car state information acquisition unit 4 and the predicted load calculation unit 6 that the predicted car in the wheelchair landing call generation floor has a value smaller than a preset load threshold. It is determined whether or not it exists (S3). The load threshold is determined from, for example, the rated load of the car.

  In the case where there is no car whose predicted load in the car on the wheelchair landing call generation floor is smaller than a preset load threshold (NO in S3), the allocation control unit 3 is the same as the general hall call for the wheelchair landing call. Is assigned (S4). Thereafter, the allocation process ends.

  On the other hand, if there is a car whose predicted load in the car on the wheelchair landing call generation floor is smaller than a preset load threshold (YES in S3), the allocation control unit 3 holds the wheelchair car call on the wheelchair landing call generation floor. It is determined whether there is a unit that is not a section (S5). In the present embodiment, considering that a downward wheelchair landing call is generated at 6F, it can be seen that for Unit A, 6F is not a wheelchair car call holding section when traveling downward. On the other hand, for Unit B, it can be seen that from 6F to 1F is the wheelchair car call holding section when traveling downward.

  When it is determined that there is a car that is not in the wheelchair car call holding section on the wheelchair landing call generation floor (YES in S5), the assignment control unit 3 assigns the car that has the shortest estimated arrival time from the relevant car. (S6). Thereafter, the process ends.

  On the other hand, when it is determined that there is no wheelchair car call holding section in the wheelchair hall call generation floor (NO in S5), the allocation control unit 3 performs the same allocation process as the general hall call for the wheelchair hall call. (S4), and the process ends.

  That is, in this embodiment, when a downward wheelchair landing call is generated at 6F, when the car A is traveling downward, the predicted load in the car at 6F is maintained at a load smaller than a preset load threshold. If so, Unit A will be assigned to the wheelchair hall call.

  As described above, according to the present embodiment, wheelchair users can use wheelchairs by calculating the allocation of a car in consideration of not only the load in the car but also the boarding space when boarding when the wheelchair user is registered. The user's convenience can be improved and the group management efficiency of the elevator can be taken into consideration.
