TECHNICAL FIELD OF THE INVENTION
The present invention relates to an elevator group management control device.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in an elevator group management control device, a waiting time at a landing is mainly used as an index for evaluating a landing call. However, if the assignment evaluation is performed only based on the waiting time at the landing, it takes time for the passengers to get to the destination floor after getting on the elevator (car), and as a result, the elevator coming later comes first You may arrive on the floor.
[0003]
In order to solve such a problem, for example, in Patent Literature 1, as a method of equalizing the boarding time, the car call duration of each floor is monitored for each car and the floor with the long car call duration is assigned. A method is disclosed for limiting the allocation of a new hall call (a hall call) to that floor of a car.
[0004]
In Patent Document 2, as a method of equalizing the boarding time and the round trip time, the number of stops during continuous operation in one direction is calculated for each car, and the number of stops in the same direction as the generated hall call is a predetermined value. The above-mentioned car discloses a method of limiting the allocation of the generated hall calls.
[0005]
In the past, at the time of a landing call, it was not known which passenger registered the landing call to register the car call on. Some things can be done. For example, Patent Document 3 discloses a landing destination call that enables assignment output for each destination floor. In Patent Literature 3, a destination button for designating a destination floor is installed at a landing, and when a destination button of a certain floor is pressed, the destination button corresponding to a car assigned to a call by pressing the destination button is supported. A method has been proposed in which a destination floor is displayed on a designated display device, and allocation is determined for each floor.
[0006]
Further, Patent Literature 4 proposes a method in which a display of an assigned car is displayed not only on a display on the car but also on an assigned car display panel provided next to a destination button.

[Problems to be solved by the invention]
However, in the above-described method, the boarding time and the round-trip time are made uniform and the assigned car is determined. However, the time from the occurrence of the landing call to the arrival at the destination floor (hereinafter referred to as service time) is the shortest. Cannot be selected.

For example, at the landing destination call on the first floor, destination calls are registered in the order of the fifth floor, the sixth floor, the seventh floor, and the ninth floor. Suppose there is a car for Unit No. In the conventional method, all the landing destination calls are assigned to the car of the A-car whose arrival time at the landing is the shortest. However, passengers going to the 9th floor must stop on the 3rd floor extra as a destination floor in the car, such as 5th floor → 6th floor → 7th floor, with a loss of 5 seconds per floor stoppage. If so, a 15 second loss would occur on the third floor. In such a case, if only the destination call to the ninth floor is assigned to the car of Car B, passengers going to the ninth floor will have to wait for an additional 10 seconds at the hall, but the car of Car A to the destination floor. Can arrive 5 seconds earlier.

[0030]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0031]
(1st Embodiment)
FIG. 1 is a diagram showing an overall configuration of an elevator group management control device according to a first embodiment of the present invention. In this example, three cars 15-1, 15-2, and 3 are placed in an n-story building. 15 shows a configuration in the case of using an elevator system 15-3 in a side-by-side elevator system.
[0032]
The group management control device 11 shown in FIG. 1 comprehensively manages the cars 15-1, 15-2, and 15-3, and determines the most optimal car when there is a hall call. Control for responding. Specifically, when there is a hall call by pressing the hall call buttons 16-1, 16-2,..., 16-n installed at each hall, the car to be managed is calculated by performing a car assignment evaluation calculation. The car having the highest evaluation value among 15-1, 15-2, and 15-3 is assigned to the hall call.
[0033]
Here, in the first embodiment, the group management control device 11 includes a service time prediction unit 12 and an assignment control unit 13. When the passenger presses the hall call buttons 16-1, 16-2,..., 16-n at the elevator hall (hall), a hall call signal at that floor is input to the service time prediction unit 12 of the group management control device 11. Is done. The service time prediction unit 12 calculates a service time from when a passenger registers a hall call to when the passenger arrives at the destination floor for each car. The assignment control unit 13 evaluates the assignment of each car based on the service time obtained by the service time prediction unit 12, thereby selecting the car having the best evaluation value and outputting an assignment command.
[0034]
The assignment command output from the assignment control unit 13 is given to the single control devices 14-1, 14-2, and 14-3. The single control devices 14-1, 14-2, and 14-3 are provided for each of the cars 15-1, 15-2, and 15-3. 15-3 is controlled. The configuration of the group management control device 11 and the single control devices 14-1, 14-2, and 14-3 is a known microcomputer control method. The outline of the operation will be described below.
[0035]
That is, at the elevator landing, when a passenger performs a landing call registration operation by pressing the landing call buttons 16-1, 16-2... 16-n, a call signal at the landing is provided in the group management control device 11. The service time prediction unit 12 is provided. The service time estimating unit 12 is configured to determine whether the passenger has traveled from the hall call registration to the destination floor based on the elevator's traveling state (car position, traveling direction, door open state), the assigned hall call information and the registered car call information. The service time until arrival at the car is calculated for each car 15-1, 15-2, 15-3, and the calculation result is output to the assignment control unit 13. The assignment control unit 13 evaluates the car assignment based on the service time calculated by the service time prediction unit 12. Then, a car having the best evaluation value is selected, and an assignment command is output to the single control devices 14-1, 14-2, and 14-3 so that the car responds to the hall call. In this case, the car with the shortest service time among the cars 15-1, 15-2, and 15-3 (the car that arrives at the destination floor earliest) is assigned to the hall call.
[0036]
Next, a processing operation according to the first embodiment of the present invention will be described in detail with reference to FIG.
[0037]
FIG. 2 is a flowchart showing the processing operation of the group management control device 11 according to the first embodiment of the present invention. In this case, the service time prediction unit 12 provided in the group management control device 11 calculates the service time. The processing procedure is shown.
[0038]
When the hall call is registered by depressing the hall call buttons 16-1, 16-2,..., 16-n, the group management control device 11 firstly controls all the units to be managed (here, the three units of the first to third units). It is determined whether or not the processes of steps A12 to A14 have been executed for each of the cars 15-1, 15-2, and 15-3 (step A11). As a result, if there is an unprocessed car (No in step A11), the group management control device 11 executes the following processing through the service time prediction unit 12.
[0039]
That is, for the unprocessed car, the group management control device 11 first calculates the estimated arrival time of the car (step A12). The estimated arrival time is the time from when the car arrives at the floor where the hall was called from the current position, and is calculated based on the traveling speed of the car and the distance from the current position to the floor where the hall was called. Can be Since the method of calculating the estimated arrival time is a known technique, detailed description thereof will be omitted.
[0040]
Next, the group management control device 11 calculates a predicted boarding time of the car assuming that the car call is registered on a floor corresponding to an intermediate floor between the hall call generation floor and the terminal floor (step A13). The predicted riding time is the time from when the passenger gets on the car to when he arrives at the destination floor. Normally, the landing call button installed at each landing is only an "up button" to specify going to the upper floor and a "down button" to specify going to the lower floor. Absent. For this reason, it is not known which car call is registered on which floor only by pressing the hall call button. In other words, it is not known how many floors the passenger wants to go. Therefore, it is assumed that a car call is registered at an intermediate floor between the landing call generation floor and the terminal floor, and the estimated riding time of the car is calculated. For example, in a building on the first to tenth floors, if there is a hall call at the first floor, the fifth floor, which is the middle floor, is predicted as the destination floor (destination floor) of the passenger.
[0041]
If the landing is equipped with a destination call registration device, etc., it is possible to know in advance which floor the passenger is going to go to at the landing, so the estimated riding time from that landing to the destination floor is accurately calculated. This will be described later in a third embodiment.
[0042]
When the predicted arrival time and the predicted boarding time are obtained in this way, the group management control device 11 calculates the predicted service time from the hall call registration for the car to the arrival at the destination floor as follows (step A14). ).
[0043]
Estimated service time = Estimated arrival time + Estimated boarding time
That is, if the predicted arrival time is a and the predicted riding time is b, a + b is calculated as the predicted service time of the car. After the calculation of the predicted service time, the process returns to step A11, and if there is an unprocessed car, the same processing as above is repeated. When the estimated service time has been calculated for all the units, the processing here ends.
[0044]
As described above, the estimated arrival time until arrival at the floor where the hall call is made for each of the cars 15-1, 15-2, and 15-3, and the passenger gets on the floor and arrives at the destination floor. A predicted service time obtained by adding the predicted ride time up to is calculated. By performing the allocation evaluation of each car based on the predicted service time, it is possible to efficiently allocate the car that can arrive at the destination floor from the floor where the hall call was made at the earliest.
[0045]
(Second embodiment)
Next, a second embodiment of the present invention will be described.
[0046]
FIG. 3 is a diagram showing the overall configuration of an elevator group management control device according to a second embodiment of the present invention. In this example, three cars 15-1, 15-2, 15 shows a configuration in the case of using an elevator system 15-3 in a side-by-side elevator system. The same parts as those in FIG. 1 (first embodiment) are denoted by the same reference numerals, and description thereof will be omitted.
[0047]
In the second embodiment, the group management control device 11 is provided with a service time prediction unit 12, an assignment control unit 13, and an assignment change unit 17, and the difference from FIG. 1 (first embodiment) is The change unit 17 has been added. This allocation change unit 17 is provided for a case where the predicted service time of a car has become worse than a predetermined value due to a change in a situation such as the addition of a car call or a car call on another floor with respect to a hall call to which a car has already been allocated. In this case, the assignment is changed to another car.
[0048]
The operation of the group management control device 11 including such an assignment changing unit 17 will be described with reference to FIG. The operation from the generation of the hall call to the output of the assignment is the same as that of the first embodiment.
[0049]
FIG. 4 is a flowchart showing a processing operation of the group management control device 11 according to the second embodiment of the present invention. Here, a processing procedure when an allocation change unit 17 provided in the group management control device 11 changes the allocation. It is shown.
[0050]
First, the group management control device 11 searches for registered hall calls (step B11), and determines whether or not all hall calls have been processed (step B12). As a result, when there is an unprocessed hall call (No in step B12), the group management control device 11 executes the following processing through the assignment changing unit 17.
[0051]
That is, the group management control device 11 first calculates a predicted service time for an unprocessed hall call as follows (step B13).
[0052]
Estimated service time = Estimated arrival time + Estimated boarding time
Note that the method of calculating the predicted service time is the same as that in the first embodiment, and a description thereof will be omitted.
[0053]
Next, the group management control device 11 determines whether or not the predicted service time is equal to or longer than a predetermined time T1 (for example, 90 seconds) (Step B14). If the time is not equal to or longer than the predetermined time T1 (No in step B14), it is determined that there is no need to change the assignment, and the process returns to step B11 to process another landing call.
[0054]
Here, when the predicted service time is a hall call for the predetermined time T1 or more, the group management control device 11 calculates a predicted service time of a car other than the assigned car (step B15). Then, when the calculation of the predicted service time is completed for the cars of all the cars (Yes in step B16), the group management control device 11 selects the car having the shortest predicted service time from these (step B17), It is determined whether or not the selected predicted service time is within a predetermined time T2 (for example, 45 seconds) (step B18). If the time is within the predetermined time T2 (Yes in step B18), the group management control device 11 changes the assignment of the assigned hall call to the car having the shortest predicted service time (step B19).
[0055]
On the other hand, if the shortest predicted service time exceeds the predetermined time T2 (No in step B18), the process returns to step B11 to search for another registered hall call. The reason for judging whether or not the predicted service time is within the predetermined time T2 in step B18 is that if the assignment is changed to a car number longer than T2 (for example, 45 seconds), the service time is long due to a change in the situation thereafter. This is because there is a possibility that the assignment will be changed to the unit.
[0056]
In this way, even if the optimal car is selected at the time of registering the hall call, if the service time changes due to changes in the situation such as adding a hall call or car call on another floor, the service time at that time By changing the assignment to another car according to the above, it is possible to direct the passenger to the car that is most suitable for the passenger (that is, the car that can quickly reach the destination floor).
[0057]
(Third embodiment)
Next, a third embodiment of the present invention will be described.
[0058]
FIG. 5 is a diagram showing an overall configuration of an elevator group management control device according to a third embodiment of the present invention. In this example, three cars 15-1, 15-2, and 3 are placed in an n-floor building. 15 shows a configuration in the case of using an elevator system 15-3 in a side-by-side elevator system.
[0059]
The third embodiment is a case where destination call registration devices 19-1, 19-2,..., 19-n are installed at each landing. The destination call registration devices 19-1, 19-2... 19-n are capable of registering destination floors at landings, and have a plurality of buttons for designating destination floors for each floor. . For example, in a case where floors having first to tenth floors are provided, ten buttons for selecting these as destination floors are provided. When a passenger presses a button corresponding to a desired destination floor at the landing, the destination floor is registered.
[0060]
Further, the group management control device 11 includes a service time calculation unit 18 and an assignment control unit 13. The service time calculation unit 18 inputs the destination call signals from the destination call registration devices 19-1, 19-2,... 19-n, so that the passenger registers the hall call for each car and then the destination floor. Calculate the service time to arrive at. The assignment control unit 13 evaluates the assignment of each car based on the service time obtained by the service time calculation unit 18, thereby selecting the car having the best evaluation value and outputting an assignment command.
[0061]
The assignment command output from the assignment control unit 13 is given to the single control devices 14-1, 14-2, and 14-3. The single control devices 14-1, 14-2, and 14-3 are provided for each of the cars 15-1, 15-2, and 15-3. 15-3 is controlled. The configuration of the group management control device 11 and the single control devices 14-1, 14-2, and 14-3 is a known microcomputer control method. The outline of the operation will be described below.
[0062]
That is, when the passenger performs a destination call registration operation by using the destination call registration devices 19-1, 19-2,..., 19-n, a destination call signal at the landing is given to the service time calculation unit 18 of the group management control device 11. Can be The service time calculation unit 18 allows the passenger to determine the destination floor from the landing call registration based on the traveling state of the elevator (car position, traveling direction, door open state), the already assigned landing call information and the registered car call information. The service time until arrival at the car is calculated for each car 15-1, 15-2, 15-3, and the calculation result is output to the assignment control unit 13. The assignment control unit 13 evaluates the car assignment based on the service time calculated by the service time prediction unit 12. Then, a car having the best evaluation value is selected, and an assignment command is output to the single control devices 14-1, 14-2, and 14-3 so that the car responds to the hall call. In this case, the car with the shortest service time among the cars 15-1, 15-2, and 15-3 (the car that arrives at the destination floor earliest) is assigned to the hall call.
[0063]
Next, a processing operation according to a third embodiment of the present invention will be described in detail with reference to FIG.
[0064]
FIG. 6 is a flowchart showing the processing operation of the group management control device 11 according to the third embodiment of the present invention. In this case, the service time calculation unit 18 provided in the group management control device 11 calculates the service time. The processing procedure is shown.
[0065]
When the destination call is registered by the destination call registration devices 19-1, 19-2,..., 19-n, the group management control device 11 firstly controls all the units to be managed (here, the first to third units of the first to third units). It is determined whether or not the processing of steps C12 to C14 has been executed for each of the cars 15-1, 15-2, and 15-3 (step C11). As a result, if there is an unprocessed car (No in step C11), the group management control device 11 executes the following processing through the service time calculation unit 18.
[0066]
That is, the group management control device 11 first calculates the predicted arrival time of the unprocessed car (step C12). The estimated arrival time is the time from when the car arrives at the floor where the hall was called from the current position, and is calculated based on the traveling speed of the car and the distance from the current position to the floor where the hall was called. Can be Since the method of calculating the estimated arrival time is a known technique, detailed description thereof will be omitted.
[0067]
Next, the group management control device 11 calculates the estimated boarding time of the car based on the information of the assigned boarding call, the registered car call, and the boarding destination call (step C13). The predicted riding time is the time from when the passenger gets on the car to when he arrives at the destination floor. In this case, since it is clear which floor the passenger goes to based on the landing destination call information, it is possible to correctly calculate the estimated boarding time to that floor.
[0068]
When the predicted arrival time and the predicted boarding time are obtained in this way, the group management control device 11 calculates the predicted service time from the hall call registration for the car to the arrival at the destination floor as follows (step C14). ).
[0069]
Estimated service time = Estimated arrival time + Estimated boarding time
That is, if the predicted arrival time is a and the predicted riding time is b, a + b is calculated as the predicted service time of the car. After calculating the predicted service time, the process returns to step C11, and if there is an unprocessed car, the same processing as described above is repeated. When the estimated service time has been calculated for all the units, the processing here ends.
[0070]
As described above, the estimated arrival time until arrival at the floor where the hall call is made for each of the cars 15-1, 15-2, and 15-3, and the passenger gets on the floor and arrives at the destination floor. A predicted service time obtained by adding the predicted ride time up to is calculated. As a result, as in the first embodiment, it is possible to make the car that can arrive at the destination floor earliest to the hall call possible. In the second embodiment, the destination call registration devices 19-1, 19-2,..., 19-n installed at the respective landings make it possible to determine which floor the passenger is going to go to. There is an advantage that the predicted service time can be calculated more accurately than in the mode and the car can be allocated.
[0071]
(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described.
[0072]
FIG. 7 is a diagram showing an overall configuration of an elevator group management control device according to a fourth embodiment of the present invention. In this example, three cars 15-1, 15-2, 15 shows a configuration in the case of using an elevator system 15-3 in a side-by-side elevator system. The same parts as those in FIG. 5 (third embodiment) are denoted by the same reference numerals, and description thereof will be omitted.
[0073]
In the fourth embodiment, the group management control device 11 includes a service time calculation unit 18, an assignment control unit 13, and an assignment change unit 17, and the difference from FIG. 5 (third embodiment) is that The change unit 17 has been added. This allocation change unit 17 is provided for a case where the predicted service time of a car has become worse than a predetermined value due to a change in a situation such as the addition of a car call or a car call on another floor with respect to a hall call to which a car has already been allocated. The assignment is changed.
[0074]
In the group management control device 11 including such an assignment changing unit 17, the operation from the generation of the hall call to the assignment output is the same as that of the third embodiment. The assignment change processing by the assignment change unit 17 is the same as that in FIG. That is, the group management control device 11 calculates the predicted service time for the registered hall call, and if the predicted service time is equal to or longer than the predetermined time T1 (for example, 90 seconds), the predicted service time of the cars other than the assigned car is calculated. Calculate and select the car with the shortest predicted service time. If the selected predicted service time is within a predetermined time T2 (for example, 45 seconds), the assigned hall call is reassigned to a car having the shortest predicted service time.
[0075]
In this way, by changing the situation such as adding a hall call or a car call on another floor, by changing the allocation when the predicted service time of the car to which the hall call is already assigned becomes worse than a predetermined value, Another car with a short service time can be made to respond.
[0076]
(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described.
[0077]
FIG. 8 is a diagram showing an overall configuration of an elevator group management control device according to a fifth embodiment of the present invention. In this example, three elevator cars 15-1, 15-2, 15 shows a configuration in the case of using an elevator system 15-3 in a side-by-side elevator system. The same parts as those in FIG. 5 (third embodiment) are denoted by the same reference numerals, and description thereof will be omitted.
[0078]
In the fifth embodiment, the group management control device 11 is provided with a service time calculation unit 18 and a multiple unit assignment control unit 20. The difference from FIG. 5 (third embodiment) is that Is changed to the plural-unit allocation control unit 20. The multiple-unit allocation control unit 20 performs an allocation evaluation based on the service time of each car calculated by the service time calculation unit 18 and when a predetermined number or more of calls are registered in the landing destination call on the same floor. , The evaluation of the assigned car is made worse by a predetermined value, and the assigned car is output to another car.
[0079]
The operation of the group management control device 11 including such a plurality of unit allocation control units 20 will be described with reference to FIG. The operation from the generation of the hall call to the service time calculation processing is the same as that of the third embodiment.
[0080]
FIG. 9 is a flowchart showing the processing operation of the group management control device 11 according to the fifth embodiment of the present invention. In this case, the group management control device 11 provided to the group management control device 11 A processing procedure for performing the assignment is shown.
[0081]
First, the group management control device 11 determines whether or not there are three or more predetermined hall destination calls that have been registered (step D11). As a result, if the number is two or less (No in step D11), the group management control device 11 calculates the predicted service time of all the units as described in the third embodiment (step D12), and An assignment command is output to the car of the car with the shortest predicted service time (step D13). On the other hand, when there are three or more registered landing destination calls (Yes in step D11), the group management control device 11 calculates the predicted service times of all the cars except the already assigned cars (step D14). An assignment command is output to the car of the car with the shortest predicted service time among all the cars except the assigned car (step D15).
[0082]
Here, the above-described processing will be described with a specific example.
[0083]
Now, as shown in FIG. 10, it is assumed that the group management operation is performed by three cars, that is, car A, car B, and car C. It is also assumed that a destination call registration device is installed at the landing on the first floor of the elevator of the 10th floor service, and that the car of the car A is traveling UP from the fourth floor to the seventh and eighth floors, Of the car No. C is traveling DOWN due to a car call from the second floor to the first floor, while the car of the car No. C is traveling by the car call from the sixth floor to the ninth and tenth floors.
[0084]
Here, a call to the second floor, the third floor, and the fourth floor is registered in the destination call registration device at the landing on the first floor, and a call to the fifth floor is further made in a state in which the destination call is assigned to the car of the car C. Assuming that is registered, the service time of each unit is compared as follows. Here, in order to facilitate the calculation, it is assumed that “1 second” per floor on the first floor, “5 seconds” when the car call is stopped, and “7 seconds” when the hall call is stopped.
[0085]
The service time when assigned to the car of Car A is 3 seconds for traveling from the 4th floor to the 7th floor, 5 seconds for stopping the car call on the 7th floor, 1 second for traveling from the 7th floor to the 8th floor, and stopping for the 8th floor car. It takes 5 seconds to travel from the 8th floor to the first floor, 7 seconds to stop at the first floor landing call, and 4 seconds to travel from the 1st floor to the 5th floor, so the total is 32 seconds.
The service time when assigned to car No. B is 3 seconds when traveling from the 6th floor to the 9th floor, 5 seconds when the car on the 9th floor is stopped, 1 second when traveling from the 9th floor to the 10th floor, and the car on the 10th floor is stopped. It takes 5 seconds to travel from the 10th floor to the first floor, 9 seconds to stop at the landing on the 1st floor, and 4 seconds to travel from the 1st floor to the 5th floor, so the total is 34 seconds.
The service time when assigned to the car of Car C is 1 second when traveling from the second floor to the first floor, 7 seconds when stopping at the first floor landing, 1 second when traveling from the first floor to the second floor, and stopping the second floor car. 5 seconds from the 2nd floor to the 3rd floor, 1 second from the 3rd floor car stop, 1 second from the 3rd floor to the 4th floor, 5 seconds from the 4th floor car stop, 4th floor to the 5th floor Since it takes one second to run, the total is 27 seconds.
[0086]
According to the above calculation result, the landing destination call to go to the fifth floor is assigned to the car of the car C which has the shortest service time. This is the case of the third embodiment. However, when the number of landing destination calls on the first floor is registered in a predetermined number or more (here, on the third floor or more), many passengers are waiting on the first floor and one car cannot be used for the entire car. Judge. Thus, in the fifth embodiment, a landing destination call to go to the fifth floor is additionally assigned to the car of the car A, which has the shortest predicted service time, except for the car of the car C currently assigned. As a result, two cars, the A-car and the B-car, are called on the first floor, so that a long waiting time due to the full capacity can be prevented.
[0087]
(Sixth embodiment)
Next, a sixth embodiment of the present invention will be described.
[0088]
FIG. 11 is a diagram showing an overall configuration of an elevator group management control device according to a sixth embodiment of the present invention. In this example, three cars 15-1, 15-2, 15 shows a configuration in the case of using an elevator system 15-3 in a side-by-side elevator system. The same parts as those in FIG. 8 (fifth embodiment) are denoted by the same reference numerals, and description thereof will be omitted.
[0089]
In the sixth embodiment, the group management control device 11 includes a service time calculation unit 18, a multiple unit allocation control unit 20, and an allocation change unit 17, which are different from FIG. 8 (fifth embodiment). Means that the assignment changing unit 17 is added. This allocation change unit 17 is provided for a case where the predicted service time of a car has become worse than a predetermined value due to a change in a situation such as the addition of a car call or a car call on another floor with respect to a hall call to which a car has already been allocated. The assignment is changed.
[0090]
In the group management control device 11 including such an assignment changing unit 17, the operation from generation of a hall call to assignment output is the same as that of the fifth embodiment. The assignment change processing by the assignment change unit 17 is the same as that in FIG. That is, the group management control device 11 calculates the predicted service time for the registered hall call, and if the predicted service time is equal to or longer than the predetermined time T1 (for example, 90 seconds), the predicted service time of the cars other than the assigned car is calculated. Calculate and select the car with the shortest predicted service time. If the selected predicted service time is within a predetermined time T2 (for example, 45 seconds), the assigned hall call is reassigned to a car having the shortest predicted service time.
[0091]
In this way, by changing the situation such as adding a hall call or a car call on another floor, by changing the allocation when the predicted service time of the car to which the hall call is already assigned becomes worse than a predetermined value, Another car with a short service time can be made to respond.
[0092]
(Seventh embodiment)
Next, a seventh embodiment of the present invention will be described.
[0093]
The seventh embodiment relates to the assignment control unit 13 provided in the group management control device 11 of the above-described first to fourth embodiments, and takes into consideration the service time for each passenger in the car, and The present invention is characterized in that allocation control is performed so as to shorten the service time.
[0094]
FIG. 12 is a flowchart showing a processing operation of the group management control device 11 according to the seventh embodiment of the present invention. Here, a processing procedure when the allocation control is performed by the allocation control unit 13 provided in the group management control device 11 It is shown.
[0095]
When a new hall call is generated, the group management control device 11 determines the selected car one by one in order to perform the following processing on the cars 15-1, 15-2, and 15-3 of all cars ( Step E11), it is determined whether the calculation of the predicted service time has been completed for all the units (step E12). If the processing has not been completed (No in step E12), the group management control device 11 temporarily assigns a newly registered hall call to the selected car and executes the following processing (step E13).
[0096]
That is, the group management control device 11 searches for registered hall calls (step E14), and determines whether the calculation of the predicted service time has been completed for all hall calls (step E15). If the calculation is not completed (No in step E15), the group management control device 11 calculates a predicted service time for a registered hall call (step E16).
[0097]
Estimated service time = Estimated arrival time + Estimated boarding time
The method of obtaining the predicted service time is as described above.
[0098]
Here, the group management control device 11 calculates the total value of the predicted service time (step E17). That is, the predicted service time is sequentially obtained for each hall call, the predicted service times are integrated, and the total value is calculated. When the calculation for all hall calls is completed (Yes in step E15), the group management control device 11 calculates a predicted service time for a new hall call (step E18), and calculates the predicted service time calculated in step E17. After adding to the total value (step E19), the process returns to step E11.
[0099]
In this way, when the calculation of the predicted service time total value is completed for each of the cars of all the cars (Yes in step E12), the group management control device 11 makes the car of the car having the smallest predicted service time total value. Is output (step E20), and the process is terminated.
[0100]
Here, the above-described processing will be described with a specific example.
[0101]
Now, as shown in FIG. 13, it is assumed that a group management operation is performed by three cars, that is, car A, car B, and car C. Also, it is assumed that destination call registration devices are installed on all floors of the elevator of the 10th floor service, and that the car of the A car is a call for the 10th floor registered in the destination call registration device on the 7th to 8th floors. During the UP traveling, the car of the car B is on standby at the 8th floor, while the car of the car B is on the 8th floor, while the car of the car B is on the 8th floor, 9th floor, and 10th floor registered in the destination call registration device on the 1st floor. I do.
[0102]
Here, assuming that a call for the sixth floor is newly registered in the destination call registration device on the second floor, the service time of each car is compared as follows. Here, in order to facilitate the calculation, it is assumed that “1 second” per floor on the first floor, “5 seconds” when the car call is stopped, and “7 seconds” when the hall call is stopped.
[0103]
At step E13 in FIG. 12, first, the second floor landing call (destination floor: 6th floor) is provisionally assigned to the car of the A car. Regarding the car of the No. A car, in step E14, the registered floor call, which is the 8th floor call, is searched, and in step E16, the predicted service time for the 10th floor specified by the 8th floor call is 1 Second (running from the 7th floor to the 8th floor) + 7 seconds (8th floor stop calling minute) + 2 seconds (line from the 8th floor to the 10th floor) = 10 seconds. Next, in step E14, the first floor landing call is searched, and in step E16, the predicted service time for the 8th floor is 14 seconds, the predicted service time for the 9th floor is 20 seconds, and the predicted service time for the 10th floor is The time is calculated to be 26 seconds, and in step E17, 10 seconds + (14 seconds + 20 seconds + 26 seconds) = 70 seconds is calculated as the predicted service time total value.
[0104]
Next, at step E18, 34 seconds is calculated as the service time of the second floor landing call which is a new landing call. Therefore, in step E19, the total predicted service time when the car is provisionally assigned to the car of the car A is 70 seconds + 34 seconds = 104 seconds.
[0105]
Similarly, when the second floor landing call (destination floor: the sixth floor) is temporarily assigned to the car of the B-th car, the following is performed.
The call to the 10th floor at the 8th floor is 10 seconds, the call to the 8th floor at the 1st floor is 26 seconds because the 2nd stop and the 6th stop are added, and the call to the 9th floor is 32 seconds, 10th floor. The outgoing call is 38 seconds, and the total predicted service time in step E17 is 10 seconds + (26 seconds + 32 seconds + 38 seconds) = 106 seconds. Further, since the call to the 6th floor at the 2nd floor is 12 seconds, the total estimated service time when the car is temporarily assigned to the car of the B car at step E19 is 106 seconds + 12 seconds = 118 seconds.
[0106]
Further, when the second floor landing call (destination floor: 6th floor) is temporarily assigned to the car of the C-th car, the situation is as follows.
The call for the 10th floor at the 8th floor is 10 seconds, the call for the 8th floor at the 1st floor is 14 seconds, the call for the 9th floor is 20 seconds, and the call for the 10th floor is 26 seconds. Further, the call for the 6th floor at the 2nd floor is (6 seconds until the response to the 2nd floor of the Unit C) + (7 seconds for opening the second floor door) + (4 seconds for traveling to the 6th floor) = 17 seconds. When all of them are added, the predicted service time total value when the car is provisionally assigned to the car of the car C at step E19 is 10 seconds + (14 seconds + 20 seconds + 26 seconds) +17 seconds = 87 seconds.
[0107]
Then, in Step E20, the total predicted service time of 104 seconds at the time of provisional assignment of the Unit A, the total predicted service time of 118 seconds at the time of provisional assignment of the Unit B, and the total value of predicted service time at the time of provisional assignment of Unit C of 87 seconds As a result of the comparison, the assignment command is output to the car of the car C having the shortest service time.
[0108]
Here, paying attention to the passenger who has designated the 6th floor at the 2nd floor, the service time when the hall call is assigned to the car of Car B is 12 seconds, and the service time when the car call is assigned to the car of Car C Is 17 seconds, and for that passenger, the car of the car B which is 5 seconds earlier than the car C is the most suitable elevator. However, in consideration of the service time of other passengers in the car of car B, assigning a call to the car on the second floor to the car of car B on the second floor would require 14 seconds for passengers going to the eighth floor. It took 26 seconds to arrive at the station. Also, a passenger who goes to the ninth floor can arrive in 20 seconds, but it takes 32 seconds, and a passenger who goes to the tenth floor in 26 seconds takes 38 seconds. That is, in order to reduce the service time of only one passenger by 5 seconds, at least three passengers take more time by 12 seconds.
[0109]
As described above, in the seventh embodiment, the service time of all the passengers is calculated, and the assignment control is performed so that the service time is reduced as a whole. In the above example, the sixth floor at the second floor is used. An outgoing call can be assigned to the C car.
[0110]
The method according to the seventh embodiment is applicable not only to the allocation control unit 13 but also to the multiple-unit allocation control unit 20 described in the fifth and sixth embodiments.
[0111]
【The invention's effect】
As described above, according to the invention, the ratio control is performed not only by the time until the car arrives at the landing, but also by the service time including the time from when the car arrives to the destination floor. Thus, the car that arrives at the destination floor earliest in each car can be made to respond to efficiently carry passengers. As a result, it is possible to realize an elevator driving service that satisfies the passengers waiting at the landing.
