  The elevator group management control device determines a response car that responds to the hall call in an elevator group composed of a plurality of cars in response to a hall call that is a request for boarding at the hall.

  The main role of the elevator group management control device is to find the best combination of the combination of hall calls generated at each floor and in each direction and the answering machine for the hall call, and manage the operation of the elevator according to the combination. That is. However, for example, when a total of 10 hall calls are generated on each floor and in each direction, and a total of 8 cars are operating, the number of combinations of response machines for each hall call is 1073741824 (= 10 of 8). Squared). In order to evaluate all such a large number of combinations and determine the best combination, a long calculation time is required.

  One of the purposes of the elevator group management control device is to efficiently manage the operation of a plurality of cars and shorten the waiting time for passengers. However, it takes time to determine the answering machine, and during that time, if the elevator cannot respond to the hall call, the purpose cannot be achieved.

  In addition, a new hall call may be generated while all combinations are being evaluated. Therefore, many conventional elevator group management control devices determine the answering machine for the hall call immediately after a new hall call is generated, and implement the arrival forecast of the answering machine on the floor where the hall call occurs. Is adopted.

  Once the answering machine that has been determined and predicted to arrive is changed, passengers at the landing are confused, so it is not usually done to review and change the answering machine. This method is generally called an immediate forecast method. In the immediate forecast method, the answering machine is determined and notified immediately, so passengers at the landing will move and arrive in front of the door where the answering machine will arrive before the answering machine arrives at the floor. There is an advantage that there is convenience.

  On the other hand, rather than deciding the answering machine immediately after the hall call is generated, the hall call for each floor / direction, the destination floor (car call) of each car, the current position / travel direction / travel speed / stop of each car The more efficient operation management is to perform operation management according to changes in operation conditions such as time. Therefore, the transportation efficiency is improved by reviewing each answering machine for all hall calls and forecasting arrival at an appropriate timing in accordance with changes in operation status. Here, this method is generally called a non-immediate forecast method. However, reviewing the answering machines for all hall calls with a single calculation (that is, re-evaluating all combinations at a time) is not a practical method at present due to the limitation of calculation time.

  Therefore, it is a practical method to review the response machines of some hall calls among all hall calls. And although it is difficult to review all landing call answering machines in one operation, all the combinations are improved little by little by repeating the review operation of some landing call answering machines several times. Ultimately, better operation management can be achieved as a whole.

  The review of some answering machines for hall calls not only affected the waiting time of passengers for the revised hall calls, but also other landing calls assigned to the answering machines before / after the review. It also affects the waiting time of passengers. In addition, the operation status changes due to the review of the response machine. For this reason, according to the change, it can be expected that the transportation efficiency will be further improved by reviewing another answering machine for another hall call.

  In the elevator group management control devices described in Patent Literatures 1 and 2, nothing is mentioned except that the assigned number determined first is changed after a certain time. Therefore, transportation efficiency is not necessarily improved for hall calls other than the revised hall call. That is, the overall transportation efficiency is not always improved.

  In addition, in the elevator group management control device described in Patent Documents 1, 3, 4, 5, and 6, a landing machine that is in a long waiting state and a different machine from the response machine that has been predicted to arrive first arrive. It describes the change / addition of the answering machine of the hall call that is judged to be unable to get on due to a full boarding due to an unforeseen hall call. Therefore, transportation efficiency is not necessarily improved for hall calls other than the specific hall call that has been reviewed. That is, the overall transportation efficiency is not always improved.

  If you want to improve all the combinations little by little by repeating the review operation of the response machines for some hall calls multiple times, and finally improve the overall operation management, review the response stations Although some ideas are required for selecting the call and the order of reviewing, there has been no mention of how to select a hall call to review the answering machine.

  In addition, there is a method in which the arrival prediction of the answering machine is not performed in part, or only the arrival at the floor is notified instead of the prediction. In the case of this method, since the arrival forecast is not made in the first place, it is possible to review and change the response machine without changing the forecast. However, since the arrival prediction is not performed, passengers at the landing cannot move in front of the corresponding response machine in advance, resulting in a demerit that it is difficult to use.

  In addition, as in Patent Document 7, there is an elevator management system that displays the current position floor of each unit on the hall instead of not performing the arrival prediction of the response unit. In this case, the passenger on the hall estimates the response car from the current position floor of each car, the moving direction, etc., and moves in front of the car. In the elevator management system, there is a case where operation management is performed to prevent each unit from passing without stopping at the floor or reversing the direction immediately before the floor. Moreover, in order to prevent the said passage and direction reversal, a response machine may be changed or added. This change / addition of response units is an operation to avoid confusion of passengers and is not intended to improve transportation efficiency. Therefore, each unit can operate without being able to pass or reverse direction, resulting in poor transportation efficiency. To do.

  Hereinafter, the present invention that enables both improvement in transportation efficiency and ease of use of passengers at a landing will be described in detail with reference to the drawings showing embodiments thereof.

<Embodiment 1>
FIG. 1 is a block diagram showing a configuration of an elevator group management apparatus 1 according to the present embodiment. As shown in FIG. 1, the elevator group management control device 1 includes an operation control unit 12, an extraction unit 13, a temporary determination unit 14, a final determination unit 15, a storage unit 16, and an activation unit 18. The elevator group management control device 1 is electrically connected to the call registration device 2 and the forecast device 3. Here, the operation control unit 12, the extraction unit 13, the temporary determination unit 14, and the final determination unit 15 are configured by software on a microcomputer.

  As shown in FIG. 2, the call registration device 2 is installed at a position away from the elevator hall. The call registration device 2 is a device for registering a hall call constituted by a passenger calling an elevator, a desired traveling direction, a desired destination floor, an ID that can be associated with these, and a combination thereof. The call registration device 2 includes a button, a touch panel, a photoelectric sensor, a microphone, a camera, a passive / active tag and its receiver, a security gate, or a combination thereof.

  As shown in FIG. 2, the forecasting device 3 is installed near the elevator hall or the entrance of the hall. The forecasting device 3 is a device for notifying the passenger of an elevator that responds to a desired traveling direction or a desired destination floor registered by the call registration device 2. The forecasting device 3 includes a lamp, a display, or a combination thereof.

  Next, each structure in the elevator group management apparatus 1 shown in FIG. 1 is demonstrated.

  The operation control unit 12 instructs the control device of each car on the floor in which each car responds and stops, such as the traveling direction of the car, running / stopping, and opening / closing of the door.

  The extraction unit 13 stores one landing call for reviewing the response machine from the hall calls of each floor, each direction, or each destination floor that are stored in the storage unit 16 and for which no response machine has been finalized. Select above.

  The temporary determination unit 14 temporarily determines, as a response car, a car that responds to the hall call registered in the call registration device 2 in each floor / direction or each destination floor or the hall call selected by the extraction unit 13. .

  The final determination unit 15 sets the response machine temporarily determined by the temporary determination unit 14 as a final response machine that is not changed and responds to the hall call extracted by the extraction unit 13 after a predetermined period has elapsed after the temporary determination. decide. The final determination unit 15 instructs the forecasting device 3 to determine the arrival forecast of the final response machine determined by the final determination unit 15.

  The storage unit 16 is finally determined by the hall call registered by the call registration device 2, the answering machine temporarily decided by the provisional decision unit 14 responding to each hall call, and the final decision unit 15 responding to each hall call. Hold the final answering machine.

  The activation unit 18 periodically activates the operation of reviewing the answering machine for the hall call using the extraction unit 13, the temporary determination unit 14, the final determination unit 15, and the storage unit 16.

  Here, the extracting unit 13 selects a hall call for reviewing the answering machine from the hall calls for which the final answering machine 15 has not yet decided the final answering machine. In other words, the extraction unit 13 reviews the response number from the new landing call (the landing call for which the responding car has not yet been determined) and the landing call for which the assignment of the temporary response unit is determined only by the temporary determination unit 14. Select the hall call to perform.

  Next, operation | movement of the elevator group management control apparatus 1 is described.

  FIG. 3 is a flowchart showing the operation of the elevator group management control device 1 according to the present embodiment.

  In step ST <b> 101, the extraction unit 13 selects a hall call for reviewing the answering machine from the hall calls held in the storage unit 16.

  In addition, after an elevator starts operation, a passenger uses the call registration device 2 at the landing on each floor, and registers each landing call in the elevator group management control device 1 at an arbitrary timing. The hall call includes a desired traveling direction, a desired destination floor, an ID that can be associated with these, and a combination thereof. The registered hall call is stored in the storage unit 16. In addition, each hall call held in the storage unit 16 is stored when the response machine determined by the temporary decision unit 14 or the final decision unit 15 described later stops at each floor in response to the hall call. It is deleted from the part 16.

  An example of a method in which the extraction unit 13 in step ST101 selects a hall call that reviews the response machine will be described below. FIG. 4 is a flowchart showing an operation of selecting a hall call for reviewing the response machine by the extraction unit 13.

  For example, all passengers on each floor operate the call registration device 2 shown in FIG. 2 to register a hall call. Then, when the elevator (car) arrives at the floor and the door is open, and a passenger who has previously registered a hall call gets on, another passenger calls the hall call with the call registration device 2 at a remote location. Is registered. As a result, when the answering machine of each hall call becomes the same, the passenger who got on first needs to wait for the following passenger in the car.

  Usually, the platform that can be seen from the car is only about the width of the door. Therefore, if the interval until the next passenger gets on after getting in the car becomes long, it is difficult for the passenger who has already boarded to judge whether the next passenger really gets on. Therefore, there is a problem that the feeling of frustration of the passenger who gets on the board increases. In order to solve this problem, it is necessary to determine the answering machine for each hall call so that the boarding interval between the passenger who rides first and the passenger who rides later falls within the boarding interval threshold.

  On the contrary, like the passengers 1, 2, and 3 in FIG. 5, although the answering machine is provisionally determined so that the boarding intervals of the front and rear passengers are within a predetermined boarding interval threshold, If the response machine is reviewed and changed, the boarding interval (boarding interval between the passenger 1 and the passenger 3) will not fit within the boarding interval threshold.

  Therefore, in step ST1011 of FIG. 4, when the extraction unit 13 changes the answering machine tentatively determined by the tentative determination unit 14 to another car, the boarding interval of the front and rear hall calls is set to a predetermined boarding interval threshold value. A hall call that falls within the range is excluded from hall calls that require a review of the answering machine (that is, excluded from the selection operation target in the extraction unit 13).

  The boarding interval can be calculated as the difference between the scheduled boarding times of the passengers. The estimated boarding time (RTTime) of each passenger is the estimated arrival time (CarYTJ) to the floor of the answering machine, the elapsed time (HCTime) after each landing call is generated, the assumed walking speed (PSGspd) of each passenger, Distance from the call registration device 2 to the forecast device 3 (DispDist), distance from the forecast device 3 to the front of the answering machine door (CarDist), elapsed time since the answering machine door was opened to the extent that it can get on and off (OPTime) And can be calculated from the current time (NowTime). Note that the predicted arrival time (CarYTJ) varies in the upward and downward directions even on the same floor.

  For example, consider a case where CarYTJ <(DispDist + CarDist) / PSGspd-HCTime, that is, the predicted arrival time before the door of the passenger's response machine is longer than the predicted arrival time of the response machine to the floor. In this case, the scheduled boarding time of the passenger is after the estimated arrival time before the door of the answering machine has elapsed. Therefore, the scheduled boarding time (RTTime) can be obtained by the following equation.

  RTime = NowTime + (DispDist + CarDist) / PSGspd-HCTime

  Also, for example, CarYTJ ≧ (DispDist + CarDist) / PSGspd−HCTime, and CarYTJ> 0, that is, the predicted arrival time before the door of the passenger's response unit is shorter than the predicted arrival time of the response unit to the floor. Suppose that the answering machine has not yet arrived at the floor. In this case, the scheduled boarding time of the passenger is after the predicted arrival time of the response machine has elapsed. Therefore, the scheduled boarding time (RTTime) can be obtained by the following equation.

  Rtime = NowTime + CarYTJ

  Also, for example, CarYTJ ≧ (DispDist + CarDist) / PSGspd-HCTime, and CarYTJ ≦ 0, that is, the answering machine has already arrived at the floor (CarYTJ ≦ 0), and the passenger has already arrived in front of the answering machine door. Think if you are. In that case, the scheduled boarding time of the passenger is past the current time, the elapsed time since the door of the answering machine opened to the extent that it can get on and off, and the passenger arrived in front of the door of the answering machine It will go back by a shorter time from the elapsed time from. Therefore, the scheduled boarding time (RTTime) can be obtained by the following equation.

  RTime = NowTime − ((OPTime) and (HCTime− (DispDist + CarDist) / PSGspd), whichever is smaller))

  It is possible to obtain the boarding interval of each passenger by taking the difference in the estimated boarding times of the passengers thus obtained. In addition, the extraction unit 13 determines whether or not the boarding call has undergone a review of the response number by comparing the obtained boarding interval and the boarding interval threshold.

  The boarding interval threshold value may not be a unique value. For example, if a car is first boarded on the floor and a passenger waiting for another passenger in the car, the possibility of being able to tolerate a short time after boarding the car is long. There is. However, if a long time elapses after boarding the car, a long boarding interval cannot be held.

  Therefore, the boarding interval threshold may be changed according to the time difference between the scheduled boarding time of the first passenger and the scheduled boarding time of the passenger of the hall call. Alternatively, when the hall call is an ID that can be associated with a desired traveling direction, a desired destination floor, and the like, the boarding interval threshold value may be changed according to the ID. That is, the boarding interval threshold may be changed depending on a certain variable.

  Now, after step ST1011, in step ST1012, the extraction unit 13 calculates a review priority for each hall call remaining as a hall call for reviewing the answering machine through step ST1011. Then, the extraction unit 13 selects the hall call having the highest review priority as the hall call for reviewing the response machine.

  The review priority (PRT) is the elapsed time (HCTime) since each hall call was generated, the number of times it was reviewed so far (RNum), the estimated arrival time (CarYTJ) of the response machine to the floor, the response machine Predicted arrival time to the destination floor (CarYTJDest), assumed walking speed of each passenger (PSGspd), distance from the call registration device 2 to the forecasting device 3 (DispDist), distance from the forecasting device 3 to the front of the answering machine door ( (CarDist) and the like, and the weighting count (Wprt).

  That is, if the function for calculating the review priority is defined as f, the review priority (PRT) can be expressed by the following equation.

  PRT = Wprt × f (HCTime, RNum, CarYTJ, PSGspd, DispDist, CarDist)

  For example, if PRT = HCTime, a hall call having a longer elapsed time since the hall call is generated is reviewed. If PRT = CarYTJDest, a hall call that takes time to arrive at the destination floor will be reviewed. Further, if PRT = CarYTJ + HCTime− (DispDist + CarDist) / PSGspd, a landing call having a longer arrival waiting time of a response machine at the landing will be reviewed. The review priority may be calculated by a combination of these.

  Which landing call answering machine is preferentially reviewed depends on the aim of the developer / designer / passenger / building owner. Moreover, you may make it a passenger and a building owner select freely.

  Further, the review priority function f may be designed so that the value of PRT decreases as the value of RNum increases, for example, PRT = HCTime / RNum. By design of the function f, it is possible to preferentially review the answering machine as the hall call is reviewed less frequently.

  Depending on the situation, there is a hall call that wants to review the response machine with priority. For example, (1) a hall call for which the answering machine has not been provisionally decided / finally decided, (2) a hall call for which there is another car scheduled to stop in the floor / direction other than the answering machine for which provisional decision has been made, ( 3) A hall call that has another car scheduled to stop in that direction on the destination floor of the hall call.

  The hall call (1) corresponds to the hall call just registered by the call registration device 2. In addition, the reason for reviewing the hall calls in (2) and (3) above is to reduce the number of stops of all elevators if the cars scheduled to stop in the relevant floor / direction can be combined into one. This is because the elevator can be efficiently managed.

  By setting the weighting factor Wprt of the priority for reviewing such hall calls ((1) to (3)) to a value larger than that of other hall calls, the above (1) to (3) It is possible to preferentially review the answering machine for the hall call.

  Further, a plurality of hall calls for reviewing response machines may be selected. In this case, hall calls are arranged in descending order of priority, and the highest number of hall calls determined in advance are selected as hall calls for reviewing the response machines.

  For example, when only one hall call that reviews the response car is selected, each index when the hall call is made to respond to each car is evaluated, and the car having the best evaluation is set as the answer car. In the first place, it has been previously evaluated that the answering machine currently tentatively responds to the hall call is the best. From this, the answering machine for the hall call is currently the answering machine that has been tentatively decided, and when the answering machine that has been tentatively decided is made to respond to the hall call again. Even if each index is evaluated, it is unlikely that there will be a significant difference from the previous evaluation results. In other words, even if each index when a response is made to the currently determined answering machine is evaluated for the hall call again, the significance of re-evaluation is small.

  However, when selecting a plurality of hall calls for reviewing the answering machines, a plurality of hall calls to which the same answering machine responds can be selected as hall calls for reviewing the answering machines. Thereby, it can be expected that the re-evaluation result of each index when responding to the response machine that is currently tentatively determined is greatly different from the previous evaluation result. This is because, as described above, when the landing call answering machine is reviewed and changed, not only the waiting time of the passengers of the revised hall call is affected, but also another answering machine assigned to the answering machine before and after the review. This is to affect the waiting time for passengers at the hall.

  Therefore, when selecting a plurality of hall calls for reviewing the answering machines, a plurality of hall calls for which the same answering machine is to respond are selected. Thereby, the significance of re-evaluation becomes great, and it becomes possible to manage the operation of the elevator more efficiently.

  Therefore, the second and subsequent hall calls are selected from the hall calls that are to be answered by the same answering machine as the first hall call (for example, the hall call with the highest priority). Is desirable. The weighting factor Wprt of the review priority of the hall call that is to be answered by the same answering machine as that of the first hall call is set to a value larger than that of other hall calls. Thus, the second and subsequent hall calls can be preferentially selected from the hall calls that are answered by the same answering machine as the first hall call.

  When step ST101 shown in FIG. 3 is completed by the operation shown in FIG. 4, next, in step ST102, the extraction unit 13 determines the answering machine provisionally determined for the hall call selected in step ST101. Are deleted from the storage unit 16. If the answering machine has not been provisionally determined for the hall call selected in step ST101, the elevator group management control device 1 continues to hold the state where the answering machine has not been provisionally decided. .

  When step ST102 ends, in step ST103, the temporary determination unit 14 narrows down and temporarily determines the response candidate cars for the hall call selected in step T101.

  The operation of provisional determination unit 14 in step ST103 (provisional determination operation of response machine) will be described with reference to the flowchart shown in FIG.

  The operation in step ST103 is performed for all the cars, and the cars other than the cars excluded in step ST103 remain as response candidate cars for the temporarily decided response car.

  In step ST1031 of FIG. 6, the provisional determination unit 14 excludes, from the response candidate cars, a car that cannot be predicted if it is determined as a response car.

  The first car that cannot be predicted for arrival (that is, the first case that is excluded from the response candidate cars at the time of provisional decision) will be described.

  For example, if a hall call is registered by designating the desired destination floor, the answering machine for the hall call with the desired destination floor will eventually be predicted to arrive at the hall and notified to the passenger who registered the hall call Must. When predicting arrival at a landing using a display, for example, as shown in FIG. 7, in the display unit of the forecasting device 3, the destination of each car (each car) frame (see the frames C1 to C7 in FIG. 7). It is possible to inform the passenger of the response machine in the form of “displaying the floor etc.”.

  However, the size of the display is finite, and in order to maintain the visibility of the display content, the character size including the numerical values in the display must also be set to a large value greater than a certain value. You must limit the number of destination floors that can be displayed inside. Therefore, the provisional determination unit 14 must provisionally determine the response number corresponding to the hall call so that the number to be displayed is smaller than the number of destination floors that can be displayed in the frame of each number.

  Therefore, if it is determined as the answering machine corresponding to the hall call, in the forecasting device 3, the car that displays more than the number of destination floors that can be displayed in the frame of the car, The temporary determination unit 14 is excluded from the response candidate machines.

  Note that the content displayed in the frame of the number machine in the forecasting device 3 is not necessarily the destination floor. For example, the direction may be used, and if the hall call is composed of an ID that can be associated with the desired direction or the desired destination floor, the ID may be displayed. Further, if the hall call can be associated with a desired direction or a desired destination floor and is composed of a video such as a face photograph taken by the camera of the call registration device 2, the video may be displayed. That is, what is displayed in the frame of each unit of the forecasting device 3 shown in FIG.

  The provisional decision unit 14 performs provisional decision processing for a car for which the number of symbols for notifying the decision result for the hall call becomes larger than the number that can be displayed in the frame of the unit for a predetermined hall call. At this time, it is excluded from the candidates for the answering machine for the predetermined hall call. In other words, the provisional determination unit 14 does not provisionally determine the car as a response machine for a predetermined hall call.

  The second car that cannot be predicted for arrival (that is, the second case that is excluded from the response candidate cars at the time of provisional determination) will be described.

  If there is a car that has been tentatively determined as the response machine for both the upward hall call and the downward hall call on the same floor, the car is normally located from the current floor position to the floor. Answer the call to the hall in the forward direction and the forward direction. Therefore, when there is a unit that has already been finalized / arrival forecasted as the answering machine for the landing call in the direction opposite to the approaching direction, the answering machine for the approaching call direction and the forward landing call on the same floor, Suppose that the machine is provisionally decided later. Then, since the relevant car must respond to the landing call in the approach direction and the forward direction first, the final decision / arrival forecast should be made as the answering machine for the approach direction and the forward call in the forward direction. .

  For example, as shown in FIG. 8, in order to respond to a hall call on the 5th floor downward (destination floor = 1F), the A machine that is traveling upward is later turned upward on the 5th floor (destination floor). = 10F) It is assumed that the answering machine for the hall call is temporarily determined. Then, the said A machine tries to respond to the entrance call in the approach direction and the forward direction first. Finally, No. A is finally determined as the answering machine for the hall call on the destination floor 10F, and the arrival prediction is made to the users on the fifth floor. That is, the forecasting device 3 predicts arrival assuming that the answering machine for both the hall call on the destination floor 1F and the hall call on the destination floor 10F is No. A.

  When such an arrival forecast is made, similarly to passengers whose destination floor is 10F, for passengers whose destination floor is already 1F, Unit A is a response machine corresponding to the landing call on destination floor 10F, It will be informed. Therefore, when Unit A arrives on the fifth floor, both passengers whose destination floor is 1F and passengers whose destination floor is 10F are likely to get on Unit A. If such a thing occurs, since the said No. A departures upward after boarding, the passenger who wished for the destination floor 1F will be confused.

  On the other hand, canceling the arrival forecast of the answering machine for the landing call on the 1st floor of the destination floor when displaying the car A as the answering machine for the landing call on the 10th floor of the destination floor, giving priority to the approach direction and the forward direction of the car. / Suppose you change. Then, the passenger who desires the destination floor 1F becomes confused at the landing on the 5th floor. In addition, the passenger who has once seen the forecasting device 3 and recognized that it is No. A may not confirm the forecasting device 3 thereafter. When such a situation occurs, if the arrival forecast of the answering machine for the hall call on the destination floor 1F is canceled / changed, a passenger who desires the destination floor 1F accidentally gets on the A machine for the 10th floor, The passenger is confused after boarding.

  Therefore, if there is a car that has already been finalized / arrival forecasted as a response machine for a hall call in the direction opposite to the car entry direction on the predetermined floor (referred to as the former hall call), the provisional decision unit 14 In the provisional determination process, the car is excluded from the response candidate cars of the car's approach direction and forward hall call (the latter hall call) on the predetermined floor. In other words, the car that is finally determined as the answering machine for the former hall call does not provisionally decide the car as the answering machine corresponding to the latter hall call.

  When using the display of the forecasting device 3 to predict the arrival at the hall, for example, as shown in FIG. It is possible to inform the passenger of the response machine. What is displayed in the frame of the destination floor may be a symbol representing the number machine. In this case, since only one unit can be predicted for each frame D1 to D18, the provisional decision unit 14 has already made a final decision / arrival forecast as a response unit for the hall call in the direction opposite to the approach direction during the provisional decision process. Are excluded from the answering candidates for the hall call in the approach direction and the forward direction on the same floor.

  The first case and the second case have been described as the units that cannot be predicted for arrival. Here, when the conditions of both cases are satisfied, the tentative determination unit 14 may delete the car from the response machine candidates during the tentative determination process. Or when satisfy | filling the conditions of any one case, the temporary determination part 14 may delete a cage from a response candidate number machine in the case of a temporary determination process.

  After the process of step ST1031, in step ST1032, if the provisional decision unit 14 decides as a response car, the car waiting time exceeds a preset car waiting time threshold from the response candidate car. To do. In other words, if it is finally determined as a response car, the temporary determination unit 14 does not provisionally determine a car whose passenger waiting time in a car exceeds a preset car waiting time threshold as a response car.

  For example, all the passengers on each floor operate the call registration device 2 shown in FIG. 2 to register the hall call. When the car arrives at the floor and the door is open, and a passenger who has previously registered a landing call gets on the board, another passenger calls the landing call at the call registration device 2 at a position away from the floor. As a result of registering, the answering machine of each hall call becomes the same. In this case, the passenger who gets on the board first needs to wait for the next passenger in the car. The time during which the previous passenger waits for departure in the car is called “in-car waiting time”.

  The waiting time in the car can be calculated as the difference between the scheduled boarding time of the passenger scheduled to board the response machine at the floor and the scheduled boarding time of the passenger scheduled to board earlier on the floor. It is.

  The method of obtaining the scheduled boarding time (RTTime) for each passenger is as described above. Since the scheduled boarding time of each passenger can be calculated, passengers scheduled to board the response machine first / last on the floor can be obtained.

  Among the passengers who board the answering machine on the floor, the passenger with the longest waiting time in the car is the first passenger who gets on the answering machine. Therefore, the waiting time in the car is calculated with reference to the first passenger, and if the waiting time in the car falls within the preset waiting time threshold in the car, the waiting time in the car is calculated on the floor. In addition, the waiting time in the car falls within the waiting time threshold value in the car for all the passengers scheduled to board the response machine.

  Therefore, even if the hall call that is reviewing the answering machine responds to the answering machine, the waiting time in the car of the passenger who is scheduled to get on the answering machine first falls within the in-car waiting time threshold. You just have to confirm that That is, the time between the scheduled boarding time of the passenger who is scheduled to board the answering machine for the first time and the scheduled boarding time of the passenger of the hall call who is reviewing the answering machine should be within the waiting time threshold in the car. .

  The in-car waiting time threshold does not have to be a unique value. For example, when the hall call is an ID that can be associated with the desired traveling direction, the desired destination floor, and the like, the waiting time threshold value in the car may be changed depending on the ID. That is, the in-car waiting time threshold may be changed depending on a certain variable.

  After the process of step ST1032, in step ST1033, if it is determined as a response car, the temporary determination unit 14 excludes from the response candidate car a car whose boarding interval exceeds a preset boarding interval threshold. In other words, if the final determination is made as a response machine, the temporary determination unit 14 does not temporarily determine the car whose passenger boarding interval exceeds a preset boarding interval threshold as a response machine. Here, the boarding interval and the boarding interval threshold are as described above.

  After the process of step ST1033, in step ST1034, the provisional determination unit 14 excludes, from other candidate reasons, a car that is not suitable as a response machine for a hall call from the response candidate cars.

  For example, if the final determination is made as a response machine, the provisional determination unit 14 does not select a car whose scheduled stop number exceeds a preset stop number threshold as a response candidate machine. Further, when the final determination is made as the response number machine, the provisional determination unit 14 does not select a car whose number in the car exceeds the preset car number threshold as a response candidate car.

  In addition, the number of passengers in the car may be the number of elevators or a value smaller than the number of passengers. If the number of passengers for each hall call is determined, the number of cars in the car can be predicted and calculated from the number of hall calls that the unit is scheduled to respond to. If all passengers register a hall call, the number of people in the car can be calculated as one person per hall call.

  Steps ST1031 to ST1034 are sequentially processed in this order. However, the processing order of steps ST1031 to ST1034 can be changed, and at least one or more of steps ST1031 to ST1034 may be performed.

  Now, after the processing of step ST103 in FIG. 3 (steps ST1031 to ST1034 in FIG. 6), in step ST104, the provisional decision unit 14 narrows down the hall call extracted in step ST101 and the step ST103. Each combination is evaluated with each response candidate machine. Then, the provisional decision unit 14 provisionally decides the hall call and the response candidate machine that are the best combination as the answer machine for the hall call.

  An example of the operation of the temporary determination unit 14 in step ST104 will be described below. For example, the temporary determination unit 14 calculates the overall evaluation value (IVAL) of each response candidate machine as follows.

  IVAL = (Wa × AVAL) + (Wsh × SHVAL) + (Wsp × SPVAL)

  Then, the provisional decision unit 14 provisionally decides the answering machine having the best overall evaluation value (IVAL) as the answering machine for the hall call.

  Here, “AVAL” is a hall waiting time evaluation value calculated from the hall waiting time. “SHVAL” is an in-car waiting time evaluation value calculated from the in-car waiting time. “SPVAL” is a stop count evaluation value calculated from the stop count. The landing waiting time evaluation value, the in-car waiting time evaluation value, and the stop count evaluation value are calculated for each car narrowed down in step ST103.

  “Wa” is a weighting factor for the hall waiting time evaluation value, “Wsh” is a weighting factor for the in-car waiting time evaluation value, and “Wsp” is a weighting factor for the stop number evaluation value.

  An example of a method for calculating each evaluation value of AVAL, SHVAL, and SPVAL will be described.

  For example, the landing waiting time (Twt) of all passengers when the answering machine for the hall call extracted in step ST101 is selected as a candidate for each answering machine narrowed down in step ST103 is calculated.

  The landing waiting time includes the elapsed time (HCTime) from the occurrence of each landing call, the estimated arrival time (CarYTJ) of the answering machine to the floor, the assumed walking speed (PSGspd) of each passenger, and the call registration device 2 The distance can be calculated from the distance to the forecasting device 3 (DispDist), the distance from the forecasting device 3 to the front of the door of the answering machine (CarDist), and the like.

  That is, if the function is defined as g, the hall waiting time (Twt) can be expressed by the following equation.

  Twt = g (HCTime, CarYTJ, PSGspd, DispDist, CarDist)

  For example, the landing waiting time (Twt) can be calculated as Twt = CarYTJ + HCTime− (DispDist + CarDist) / PSGspd.

  In the case of a normal call registration device 2 that presses the up / down button at the landing, if the button is pressed by the first passenger who has arrived at the landing on the floor and has the desired traveling direction, the desired traveling direction Subsequent passengers who do not press the call registration device 2. Therefore, the landing waiting time (Twt) calculated by the above formula can only calculate the landing waiting time of the first passenger.

  However, in the case of the call registration device 2 in which the hall call is registered based on the desired destination floor, the desired direction of travel, the ID that can be associated with the desired destination floor, etc., it is necessary to call and register subsequent passengers. In this case, it is possible to calculate the landing waiting time of not only the first passenger but also the following passengers by the above formula. Therefore, each response candidate machine can be evaluated including not only the landing waiting time of the first passenger but also the waiting time of the subsequent passenger.

  If the function is defined as h, AVAL can be expressed as

  AVAL = h (Twt)

  For example, AVAL can be calculated as:

AVAL = Σ (TTwt− (Twt of each passenger on each floor when the answering machine for the hall call is the answering machine)) ² −Σ (TTwt− (the answering machine for the hall call is the answering machine) Twt of all passengers on each previous floor)) ²

  “TTwt” is a target hall waiting time. The smaller the difference from the target landing waiting time, the smaller the value of AVAL. The smaller the value of IVAL, the better. If the value of AVAL is smaller, the evaluation is better.

  The elevator group management control device 1 with TTwt set to 0 manages the operation so that the landing waiting time becomes 0. Since the number of cars is limited, if the target landing waiting time is set to an excessively small value, passengers with a short landing waiting time are likely to be generated while passengers with a very long landing waiting time are generated. On the other hand, when the landing waiting time is set to an appropriate value, passengers with a short landing waiting time are reduced, but passengers with a very long landing waiting time are also reduced. That is, the hall waiting time can be smoothed.

  Further, “TTwt” may not be a unique value. For example, the value of TTwt may be changed according to each floor, each desired traveling direction, each desired destination floor, ID, time, and the like. That is, the in-car waiting time threshold may be changed depending on a certain variable.

  For example, when changing TTwt by ID, that is, changing TTwt by passenger, operation management can be performed for a specific passenger so that the landing waiting time is shortened. It will be possible to manage operations according to important customers, positions and positions.

  Next, an example of a SHVAL calculation method will be described.

  For example, the waiting time (Twi) in the car of all passengers is calculated when the answering machine of the hall call extracted in step ST101 is each answering candidate car narrowed down in step ST103.

  The waiting time in the car (Twi) can be calculated from the scheduled boarding time (RTTime) of each passenger. As mentioned above, each passenger's scheduled boarding time (RTTime) is the estimated arrival time (CarYTJ) of the answering machine to the floor, the elapsed time (HCTime) from the occurrence of each hall call, and the assumed walking speed of each passenger. (PSGspd), distance from the call registration device 2 to the forecasting device 3 (DispDist), distance from the forecasting device 3 to the front of the answering machine door (CarDist), and the process since the answering machine door was opened to the extent that it can be boarded It can be calculated from the time (OPTime) and the current time (NowTime).

  If the function is defined as i, SHVAL can be expressed by the following equation.

  SHVAL = i (Twi)

  For example, SHVAL can be calculated as:

SHVAL = Σ (Twi of each passenger on each floor when the answering machine for the hall call is the answering machine) ²⁻ Σ (All passengers on each floor before the answering machine for the hall call is the answering machine) (Twi) ²

  The smaller the in-car waiting time (Twi), the smaller the value of SHVAL. The smaller the value of IVAL, the better. If the value of SHVAL is smaller, the evaluation is better.

  Next, an example of the SPVAL calculation method will be described.

  For example, SPVAL can be calculated from the total number of planned stoppages of all the cars when the answering machine of the hall call extracted in step ST101 is each response candidate car narrowed down in step ST103.

  If the function is defined as j, SPVAL can be expressed as the following equation.

  SPVAL = j (total planned number of stops)

  For example, SPVAL can be calculated as:

SPVAL = Σ (total number of scheduled stops when the answering machine for the hall call is the answering machine) ²⁻ Σ (total number of scheduled stops before the answering machine for the hall call is the answering machine) ²

  The smaller the total planned stoppage number, the smaller the value of SPVAL. If the value of IVAL is smaller and is the best, the smaller the value of SPVAL, the better the evaluation.

  Each weight count Wa, Wsh, Wsp may not be a unique value. You may make it change with traffic patterns, such as time, the number of hall calls, the number of car calls, the number of halls, the number of passengers in a car, and an UP peak or a DOWN peak. That is, the weighting factors Wa, Wsh, and Wsp may be changed depending on a certain variable.

  In this embodiment, the evaluation values of AVAL, SHVAL, and SPVAL are included as the constituent elements of IVAL. However, the evaluation values may be included, and other components described in the prior literature may be included. You may make it comprise in part or all of the evaluation value.

  After the provisional determination unit 14 provisionally determines the answering machine for the hall call in step ST104, in step ST105, the provisional determination unit 14 provisionally determines the hall call selected in step ST101 and the step ST104. The response unit for the received hall call is stored in the storage unit 16.

  In step ST106, the final decision unit 15 selects a combination satisfying a predetermined condition from the combination of the hall call and the response machine held in the storage unit 16 in the subsequent response machine review process. Final decision is made as a combination in which the answering machine is not changed. Then, the final determination unit 15 instructs the forecasting device 3 to predict the arrival of the answering machine for the finally determined hall call.

  An example of the operation of the final decision unit 15 in step ST106 will be described below. FIG. 10 is a flowchart showing an operation in which the final decision unit 15 finally decides the combination in which the response unit is not changed, and instructs the forecasting apparatus 3 to arrive at the response unit.

  In step ST1061 of FIG. 10, the final determination unit 15 extracts combinations that should not be final determined.

  For example, on the same floor, there is an answering machine that has been tentatively determined as the answering machine for both the upward hall call and the downward hall call, and the answering machine for the hall call in either direction is already final. Suppose you have a car that has been determined / arrived. In such a case, if the answering machine for the hall call in the other direction on the same floor is finally decided for the car later, passengers in the hall call in the direction opposite to the approach direction will be confused. .

  For example, as shown in FIG. 8, in order to respond to a hall call on the 5th floor downward (destination floor = 1F), the A machine that is traveling upward is later turned upward on the 5th floor (destination floor). = 10F) Assume that the final decision is made as the answering machine for the hall call. Then, the machine A responds first to the landing call in the approach direction and the forward direction, and departs upward after the fifth floor stop.

  The forecasting device 3 predicts the arrival of the answering machine for the hall call on the destination floor 1F and the hall call on the destination floor 10F as the A machine. Therefore, when No. A arrives on the 5th floor, there is a high possibility that passengers at the destination floor 1F and passengers at the destination floor 10F will get on the No. A machine. If it does so, if the said machine A departs upwards after boarding, the passenger of the destination floor 1F will be confused.

  Canceling / changing the arrival forecast of the answering machine for the landing call on the 1st floor of the destination floor when displaying the car A as the answering machine for the landing call on the 10th floor of the destination floor, giving priority to the approach direction and forward direction of the car Suppose that Then, passengers on the destination floor 1F are confused at the landing. In addition, the passenger who has once seen the forecasting device 3 and recognized that it is No. A may not confirm the forecasting device 3 thereafter. Therefore, even if the arrival forecast of the answering machine for the hall call on the destination floor 1F is canceled / changed, the passengers on the destination floor 1F are confused after boarding.

  Therefore, on the same floor, there is an answering machine that has been tentatively determined as the answering machine for both the upward hall call and the downward hall call. The answering machine for the hall call in either direction has already been finalized. / If there is a response unit that is predicted to arrive, the combination of the hall call in the other direction and the response unit that is provisionally determined on the same floor is a combination that must not be finally determined (step ST1061). ).

  In other words, it is assumed that there is a car that has been determined by the final determination unit 15 as a final response machine of one of an upward hall call and a downward hall call on a predetermined floor. In this case, final determination unit 15 does not determine the other final answering machine of the upward hall call and the downward hall call on the predetermined floor (step ST1061).

  Next, in step ST1062, the final decision unit 15 determines the final decision among the combinations other than the combinations excluded in step ST1061 in the combination of the hall call held in the storage unit 16 and the response machine. The combination of hall call and answering machine is extracted. Hereinafter, the extraction method of the combination in the final determination unit 15 will be described in detail.

  First, the first extraction method will be described.

  As described above, the transportation efficiency is higher when the response unit is reviewed for as long as possible according to the change in the operation status. However, it is easier for passengers at the landing to move to the front of the answering machine and wait for the arrival before the answering machine arrives at the floor.

  Therefore, when the predicted arrival time (CarYTJ) of the answering machine to the floor is equal to or less than the time required for the passenger to move (CarDist / PSGspd) the distance from the forecasting device 3 to the front of the answering machine door (CarDist) The combination of the hall call and the answering machine on the floor is the final combination. That is, the combination of the hall call and the answering machine on the floor that satisfies CarYTJ ≦ CarDist / PSGspd is the final combination.

  That is, in all the combinations of the hall call and the answering machine, the final determination unit 15 predicts the arrival time of arrival of the answering machine tentatively decided with respect to the given hall call on the given floor at the given floor ( It is determined whether or not (CarYTJ) has become equal to or less than the time (CarDist / PSGspd). If there is a combination in which the predicted arrival time (CarYTJ) is equal to or less than the time (CarDist / PSGspd), the final determination unit 15 extracts the combination. Then, the final decision unit 15 finally decides the combination of the extracted hall call and its response machine.

  If the value to be compared with the predicted arrival time (CarYTJ) is a value (α) larger than the time CarDist / PSGspd, the passengers at the landing will be in front of the response unit before the response unit arrives at the floor. You can move and wait for arrival.

  That is, the combination of the hall call and the answering machine on the floor where CarYTJ <α may be the final combination.

  If the response machine has already arrived at the floor, CarYTJ is 0. Therefore, according to the above conditions, the combination of the hall call and the answering machine on the floor is the final combination.

  Next, the second extraction method will be described.

  As described above, the transportation efficiency is higher when the response unit is reviewed for as long as possible according to the change in the operation status. On the other hand, it is easier for passengers at the hall to move to the front of the answering machine and wait for arrival before the answering machine arrives at the floor. Therefore, it is preferable that the final determination unit 15 extracts the combination to be finally determined by using the first extraction method.

  By the way, it is assumed that the passengers at the hall have not yet moved from the call registration device 2 to the forecast device 3 after the hall call registration by the call registration device 2. In this case, it is meaningless to finally determine the combination of the hall call and the answering machine and predict the arrival by the forecasting device 3.

  If it does so, until the said passenger finishes moving to the forecasting apparatus 3, the transportation efficiency is higher when the response machine with respect to the said hall call can be reviewed.

  Therefore, the elapsed time (HCTime) from when the hall call is generated (registered) is equal to or longer than the distance (DispDist / PSGspd) required for the passenger to travel the distance (DispDist) from the call registration device 2 to the forecasting device 3 In some cases, the combination of the hall call and the answering machine on the floor is the final combination. In other words, the combination of the hall call and the answering machine on the floor that satisfies HCTime ≧ DispDist / PSGspd is determined to be the final combination.

  That is, in all combinations of the hall call and the answering machine, the final determination unit 15 determines whether or not the elapsed time (HCTime) is equal to or longer than the time (DispDist / PSGspd). If there is a combination whose elapsed time (HCTime) is equal to or greater than the time (DispDist / PSGspd), the final determination unit 15 extracts the combination. Then, the final determination unit 15 finally determines the extracted combination as a final response machine.

  If the value to be compared with the elapsed time (HCTime) is a value (β) smaller than the time DispDist / PSGspd, the answering machine is finally determined by the time passengers arrive at the forecasting device 3 It will be. That is, the combination of the hall call and the answering machine on the floor where HCTime> β is satisfied may be the final combination.

  Next, the third extraction method will be described.

  When the forecasting device 3 is installed near the entrance of the hall, a large number of passengers may stop in front of the forecasting device 3 in order to wait for the response machine to be notified. Then, a large number of passengers are in the way, and a certain passenger who has recognized the notification of the response machine cannot move to the front of the door of the response machine.

  Therefore, although the movement from the call registration device 2 to the forecasting device 3 has been completed (HCTime ≧ DispDist / PSGspd), the number of passengers (PNum) that has not been notified yet and that has not been notified yet is preset. When the number of passengers exceeds the threshold value, the final determination unit 15 performs the following process.

  That is, the final determination unit 15 examines the elapsed time (HCTime) for each passenger of the number of passengers (PNum). Then, in order from the longest elapsed time (HCTime), the hall call related to the elapsed time (HCTime) and the answering machine for the hall call are extracted as a combination to be finally determined. Then, the final determination unit 15 finally determines the extracted combination as a final response machine.

  Thereby, the number of passengers (PNum) waiting for the notification of the response car in front of the forecasting device 3 is set to be equal to or less than the passenger number threshold. It is assumed that the passenger count threshold is a changeable parameter and is held by the final determination unit 15.

  In the above description, the combination of the hall call and its answering machine is finally determined in order from the longest elapsed time (HCTime). However, the final determination operation of the final determination unit 15 when the number of passengers (PNum) is equal to or greater than a preset passenger number threshold need not be limited to the method using the elapsed time.

  For example, the combination of the hall call and its response number may be finally determined in order from the shortest predicted arrival time (CarYTJ) of the response number. Moreover, you may finally determine the combination of a hall call and its response machine in order with a short landing waiting time (Twt). Moreover, you may finally determine the combination of a hall call and its response machine in order with a short in-car waiting time (Twi). Or the value of the result of the four arithmetic operations combining some or all of the elapsed time (HCTime), the predicted arrival time (CarYTJ), the landing waiting time (Twt) and the waiting time in the car (Twi), in order from the best The combination of the hall call and the answering machine may be finally determined.

  That is, when the number of passengers (PNum) is equal to or greater than a preset number of passengers, the final determination unit 15 uses the parameters related to the time that can be measured by the elevator group management control device 1 to determine the final response number. To decide.

  In addition, the 1st-3rd extraction method was demonstrated about the method of the final determination of the combination of a hall call and its response machine. Here, the final determination of the combination of the hall call and the answering machine may be performed by the extraction method constituted by “and” or “or” of each extraction method. Moreover, it is not always necessary to apply all the extraction methods. That is, the combination of the hall call and the response machine for the hall call may be finally determined by an extraction method constituted by a part of the first to third extraction methods or a combination that is not all.

  After determining the final response machine in step ST1062, in step ST1063, the final decision unit 15 determines the final response machine determined in step ST1062 and the hall call corresponding to the final response machine as a prediction device. 3 to send. And the forecasting apparatus 3 alert | reports the response machine determined in step ST1062 as a response machine with respect to a corresponding hall call.

  Thus, the operation of step ST106 is completed, and the operation shown in FIG.

  The starting unit 18 periodically starts a series of operations from step ST101 to step ST106 shown in FIG.

  In the conventional elevator group management control device that does not review the response machine, when the hall call is registered by the call registration device, the answer machine for the hall call may be determined once. For this reason, in the conventional elevator group management control apparatus, the operation | movement which determines a response machine is not repeated periodically.

  On the other hand, in the elevator group management control device 1 of the present invention, the operation for determining the hall call and its response machine is repeated as many times as long as there is still time for reviewing the response machine (FIG. 3). Repeat operation). Therefore, in the elevator group management control device 1 according to the present invention, the answering machine corresponding to the hall call can be changed according to the change of the operation status, the appropriate operation management is performed, and the transportation efficiency is improved.

  Moreover, as shown in FIG. 2, the call registration apparatus 2 may be far from each elevator. In this case, the passenger who registered the hall call by the call registration device 2 is the distance from the call registration device 2 to the forecast device 3 (DispDist) or the distance from the forecast device 3 to the front of the answering machine door (CarDist). If you do not move, you cannot get on the answering machine corresponding to the hall call registered by the passenger. Therefore, when the response machine arrives at the floor earlier than the passenger moves before the door of the response machine, the response machine needs to open the door until the passenger can get on the floor.

  Therefore, the operation control unit 12 sets the time for opening the door (FTime) on the floor, the estimated arrival time of the answering machine to the floor (CarYTJ), and the elapsed time (HCTime) after each hall call is generated. ), The estimated walking speed (PSGspd) of each passenger, the distance from the call registration device 2 to the forecasting device 3 (DispDist), the distance from the forecasting device 3 to the front of the answering machine door (CarDist), and the like.

  If the function is defined as k, time (FTime) can be expressed by the following equation.

  FTime = k (CarYTJ, HCTime, PSGspd, DispDist, CarDist)

  For example, it is possible to calculate as FTime = (DispDist + CarDist) / PSGspd− (HCTime of the passenger who will finally get on the corresponding response machine) −CarYTJ.

  In the case of the time (FTime) represented by the above formula, the door starts to close immediately after the passenger gets on. Therefore, if the time (FTime) is not designed to be somewhat longer than the above formula, a situation may occur in which a passenger is caught in the door.

  Therefore, it is desirable to calculate using FTime = (DispDist + CarDist) / PSGspd− (HCTime of the passenger who is scheduled to get on the response machine at last) −CarYTJ + γ. γ is an addition value for designing a longer time (FTime), and is held in the operation control unit 12 in advance.

  Further, in a conventional elevator group management control device, a car may be dispatched in advance to a specific crowded floor of a building regardless of the presence or absence of passengers at the landing. The car dispatched in advance may open a door for a certain time (ω), stop at the floor, and wait for a passenger to get on the car.

  However, as shown in FIG. 2, when the call registration device 2 is far away, the presence or absence of a passenger who is scheduled to board within “(DispDist + CarDist) / PSGspd” seconds is known. Therefore, if there are no passengers scheduled to board, there is no need to open the door and wait for boarding for “ω− (DispDist + CarDist) / PSGspd” seconds or more.

  When the distance (DispDist + CarDist) is long, the time to open the door and wait for getting on is 0 second or less. In this case, it means that there is no need to open the door and wait for the ride.

  If there is a passenger who is scheduled to board, the door is opened for the time FTime as in the present embodiment, so the passenger will not be late. Thereby, the time which opens a door uselessly and stops a car on the said floor can be shortened. Therefore, since the car can start early, the transportation efficiency is improved.

  In the present embodiment, for convenience of explanation, as shown in FIG. 2, the configuration in which the call registration device 2 is installed far from the forecasting device 3 is illustrated. However, it is not necessary to limit that the call registration device 2 is installed far from the forecasting device 3. For example, if the call registration device 2 and the forecasting device 3 are installed in the vicinity (if both devices 2 and 3 are installed in the vicinity of the car), “DispDist” and “CarDist” are , 0 may be performed as described above.

  As described above, according to the first embodiment of the present invention, the landing call response machine is changed over a plurality of times with respect to the hall call for which the final answering machine has not been determined. You can review it. Thereby, transportation efficiency improves.

  Further, according to the first embodiment of the present invention, the final determination unit 15 finally determines the response machine for the hall call, and the prediction apparatus 3 notifies the response machine. Therefore, the passenger can move in front of the answering machine and wait for arrival before the answering machine arrives at the floor. And since the arrival prediction of a landing is not changed, the convenience of the passenger of a landing can also improve the response machine finally decided.

  Further, in the present embodiment, when the answering machine is changed, the extraction unit 13 uses the hall call in which the boarding interval of the front and rear passengers deviates from within the boarding interval threshold value as the hall call in which the review of the answering machine has occurred. Exclude from

  Therefore, it is possible to prevent problems such as an unnecessarily long passenger boarding interval.

  In the present embodiment, the extraction unit 13 calculates the review priority (PRT) of the hall call using a plurality of parameters, and the hall where the review of the response machine has occurred based on the priority (PRT). Determine the call.

  Therefore, it is possible to appropriately select a hall call for reviewing the answering machine, and as a result, it is possible to effectively improve transportation efficiency.

  Moreover, in this Embodiment, the temporary determination part 14 judges whether it selects as a response candidate number machine according to the number of the symbols displayed on the forecasting apparatus 3. FIG.

  Therefore, a car that cannot be predicted for arrival in the forecasting device 3 can be excluded from the response unit, and a problem that the response unit cannot be predicted for arrival by the forecasting unit 3 can be prevented.

  Moreover, in this Embodiment, the temporary determination part 14 is performing the process which is not selected as a response candidate machine under a predetermined condition.

  Therefore, prevent problems such as “cannot predict arrival”, “waiting time in car too long”, “boarding interval too long”, “too many stops” and “too many people in car” be able to.

  Moreover, in this Embodiment, the temporary determination part 14 is a response candidate machine which belongs to the best combination among the combinations of the hall call selected by the extraction part 13, and each response candidate machine selected by the said temporary determination part. Is temporarily determined as the answering machine for the hall call.

  Therefore, it is possible to provisionally determine an appropriate response machine and improve transportation efficiency.

  Further, in the present embodiment, the final determination unit 15 determines the final response of the downward hall call on the predetermined floor as a car determined as the final response machine of the upward hall call on the predetermined floor, for example. We do not decide as unit.

  Therefore, it is possible to prevent a confusion such that a passenger who desires to move in the upward direction moves downward by mistake.

  In the present embodiment, the final decision unit 15 uses the predetermined condition (first to third extraction methods) to determine the decision of the final response machine.

  Therefore, it is possible to review the answering machine for the hall call several times in response to changes in the operating status, to improve the transportation efficiency, to appropriately forecast the arrival of the hall, and to consider the ease of use of passengers at the hall it can.

  Further, in the present embodiment, the operation control unit 12 sets the time for opening the door on a predetermined floor, the estimated arrival time of the car to the predetermined floor, the elapsed time after the landing call is generated, Calculation is performed using the assumed walking speed and the travel distance of the passenger.

  Therefore, it is possible to appropriately determine the time during which the door is open, and it is possible to reduce useless stop time and improve transportation efficiency while reliably getting passengers on the predetermined floor.

<Embodiment 2>
Next, an elevator group management control apparatus according to Embodiment 2 of the present invention will be described.

  In the first embodiment, the response machines for each hall call in each floor and each direction are reviewed. However, there are usually many hall calls with different destination floors even on the same floor and in the same direction. In such a case, if the hall calls are reviewed one by one, it takes time to calculate. In this way, if the calculation time is required for a long time, there is a high possibility that the answering machines for all hall calls cannot be reviewed. Moreover, if the response machine is displayed on the forecasting device 3 for each hall call, there is a problem that the response machine cannot be displayed on the forecasting device 3.

  Therefore, in the present embodiment, a method for grouping a plurality of hall calls and reviewing the response machines in units of groups will be described. FIG. 11 is a block diagram showing a configuration of an elevator group management control device 50 according to Embodiment 2 of the present invention.

  The elevator group management control device 50 has substantially the same configuration as the elevator group management control device 1 according to the first embodiment. Therefore, in the following, only portions of the elevator group management control device 50 and the elevator group management control device 1 that are different in configuration will be described. In both apparatuses 1 and 50, the same reference numerals are assigned to the same functional blocks. Since the functional blocks to which the same reference numerals are assigned have been described in the first embodiment, description thereof is omitted here.

  The elevator group management control device 50 is also electrically connected to the group notification device 4. Further, a grouping unit 17 is additionally configured in the elevator group management control device 50. The grouping unit 17 is configured by software on a microcomputer.

  The group notification device 4 may be installed as a separate member near the call registration device 2 as shown in FIG. 12, or as the same casing as the call registration device 2 as shown in FIG. May be. When a passenger registers a hall call using the call registration device 2, the group notification device 4 notifies the passenger of a group symbol indicating the group to which the hall call belongs. The group notification device 4 includes a lamp, a display, a speaker, and a combination thereof for the notification.

  The grouping unit 17 groups the hall calls registered by the plurality of passengers in the call registration device 2.

  Next, the operation of the elevator group management control device 50 will be described. FIG. 14 is a flowchart showing a processing procedure of the operation of the elevator group management control device 50.

  In step ST201, the grouping unit 17 groups the hall calls that are not yet grouped from the hall calls held in the storage unit 16.

  In addition, after the elevator starts operation, passengers call registration of hall calls composed of desired travel directions, desired destination floors, IDs that can be associated with these, and combinations thereof. It is possible to register in the elevator group management control device 50 at an arbitrary timing using the device 2. The registered hall call is stored in the storage unit 16 as needed.

  In addition, each hall call held in the storage unit 16 is stored when the response machine determined by the temporary determination unit 14 or the final determination unit 15 described later stops at each floor in response to the hall call. 16 is deleted.

  Therefore, a hall call that has just been registered in the elevator group management control device 50 at the most recent timing may be held in the storage unit 16 as a hall call that has not yet been grouped. Become a call.

  In addition, when the hall call which is not grouped is not hold | maintained in the memory | storage part 16, operation | movement of step ST201 and step ST202 of the next process is abbreviate | omitted.

  An example of the operation of the grouping unit 17 in step ST201 (that is, hall call grouping processing) will be described below. FIG. 15 is a flowchart illustrating in detail the operation of step ST201 in the grouping unit 17.

  In step ST2011 in FIG. 15, the grouping unit 17 excludes groups that should not be assigned to the ungrouped hall call from existing groups. The exclusion method will be described in detail below.

  When grouping hall calls, the response machines are reviewed in units of groups, and the response machines are provisionally determined (decision by the provisional decision unit 14) / final decision (decision by the final decision unit 15). Further, when the hall call is assigned to any of the existing groups, the response machine of the group may have been provisionally determined / finally determined. For this reason, assigning to a group may temporarily / finally determine the response machine.

  As described in the first embodiment, when a response machine is tentatively determined / finally determined, the waiting time in the car, the boarding interval, and the number of people in the car are the waiting time threshold in the car, the threshold value in the riding interval, and the number of people in the car. Must be within threshold.

  Therefore, if the answering machine for the hall call is tentatively decided / finally decided as the answering machine for the group as a result of the assignment of the hall call to the group, the waiting time in the car, the boarding interval and the number of people in the car are The hall call must not be assigned to a group that does not fit within the internal waiting time threshold, the boarding interval threshold, or the car passenger threshold. Therefore, a group that satisfies the above condition is a group that should not be assigned the hall call. The method for calculating the waiting time in the car, the boarding interval, and the number of people in the car is the same as the method described in the first embodiment.

  After step ST2011, in step ST2012, the grouping unit 17 selects a group that meets the conditions from among the existing groups excluding the group excluded in step ST2011, and assigns the hall call to the group. . The conditions will be described next.

  First, the first condition will be described.

  For example, when the hall call is registered by the desired destination floor, or when it is registered by an ID that can be associated with the desired destination floor, the grouping unit 17 identifies the same hall call registered from the same floor. Assign to a group consisting of hall calls with the desired destination floor.

  Here, if there are a plurality of corresponding groups, the group with the longest predicted arrival time (CarYTJ) to the floor of the response unit is selected (that is, there are a plurality of corresponding groups). (If so, the grouping unit 17 selects a group that satisfies the condition (first condition)).

  In addition, when there are a plurality of corresponding groups, the case where the grouping unit 17 selects the group with the longest predicted arrival time (CarYTJ) to the floor of the response unit has been mentioned. May be performed.

  For example, when there are a plurality of corresponding groups, the grouping unit 17 may select a group with the shortest estimated arrival time (CarYTJ) of the response machine to the floor, or the number of people in the car of the response machine The grouping unit 17 may select a group having the minimum / maximum. Alternatively, the grouping unit 17 may select a group in which the waiting time in the car of the answering machine is minimum / maximum, and the longest elapsed time (HCTimeMax) in the hall call constituting the group is the longest / shortest. The grouping unit 17 may select such a group. Alternatively, when there are a plurality of corresponding groups, the grouping unit 17 may randomly select one group from the plurality of groups. These can be grasped as the first condition.

  Next, the second condition will be described.

  When a group to be assigned is selected according to a group that matches the first condition, at least as many groups as the desired destination floor are created. As described in the first embodiment, if a large number of hall call response machines are to be reviewed one by one, the answer machine cannot be displayed on the forecasting device 3. For this reason, in the second embodiment, a plurality of hall calls are grouped. Therefore, the second condition relates to a condition (method) for reducing the number of groups.

  For example, when notifying a response machine to passengers, it is necessary to maintain the visibility of display contents with a finite display size. For this reason, as shown in FIG. 16, when notifying the passenger of the response car in the “frame of each car (a form in which a group or the like is displayed in the signs Q <b> 1 to Q <b> 7 in FIG. 16”) Therefore, the number of groups that can be displayed in the frame (Q1 to Q7) of each unit is also finite.

  The number of groups that can be displayed in the frame (Q1 to Q7) of each unit is assumed to be “GENum”. On the other hand, if the hall calls on the same desired destination floor belong to the same group and respond to the same answering machine, the number of elevator stops can be reduced. Therefore, from the viewpoint of transportation efficiency, it is effective to assign as many landing calls on the same desired destination floor as possible to the same group.

  However, if only one desired destination floor is assigned to one group, the total number of groups does not decrease even when compared with the first condition. Therefore, the target desired destination floor number assigned to one group is set.

  First, if “target desired destination floor number × GENum × number of cars ≧ total floor number −1”, all passengers with each desired destination floor on that floor are assigned to some group and the response number is determined I can't.

  Therefore, the target desired destination floor number U1 can be calculated as the following equation.

  Target desired destination floor number U1 = (Number of floors-1) / (GENum x number of cars) + 1

  However, in the above formula, the decimal part is rounded down.

  In addition, when “GENum” is small, the operation efficiency deteriorates unless the desired number of desired destination floors per group is set to a certain large value. For example, if GENum = 1 and a 10-story building has 8 cars, the target desired destination floor number U1 = 2. However, if the target desired destination floor number is set to 2, when three or more desired destination floor landing calls are generated from the floor, two or more cars will always respond to the floor. If a large number of cars are responded to one floor, the waiting time for passengers on the floor becomes shorter, but for passengers on other floors, the waiting time becomes longer, resulting in overall transportation. Efficiency deteriorates.

  Therefore, it is better to provide a minimum value (Low) for the target desired destination floor number. That is, the target desired destination floor number U2 = Low is calculated. “Low” may be stored in the grouping unit 17 in advance, or the grouping unit 17 calculates the number of cars in the car, the speed of the car, the number of service floors, the threshold for the number of stops, and GENum. You may make it do.

  The final desired destination floor number may be the larger of the desired destination floor number U1 and the desired destination floor number U2.

  And if the hall call is registered by the desired destination floor, or if it is registered by an ID that can be associated with the desired destination floor, the number of desired destination floors of the hall call constituting the group is the target desired destination floor Groups less than the number are set as a group that satisfies the second condition. Therefore, the grouping unit 17 selects a group that matches the second condition.

  If there are a plurality of corresponding groups, the grouping unit 17 finally sets the group having the longest estimated arrival time (CarYTJ) to the floor of the response machine as a group that satisfies the second condition. select.

  In the above, when there are a plurality of corresponding groups, the group with the longest predicted arrival time (CarYTJ) to the floor of the answering machine is finally selected as the group meeting the second condition. Mentioned. However, when there are a plurality of corresponding groups, the grouping unit 17 finally sets the group having the shortest estimated arrival time (CarYTJ) to the floor of the response machine as a group that satisfies the second condition. You may choose.

  Alternatively, when there are a plurality of corresponding groups, the grouping unit 17 may finally select the group having the minimum / maximum number of people in the car of the answering machine as the group meeting the second condition, The group having the minimum / maximum waiting time in the car of the answering machine may be finally selected by the grouping unit 17 as a group meeting the second condition, or in the hall call constituting the group The grouping unit 17 may finally select the group having the longest / shortest elapsed time (HCTimeMax) as the group meeting the second condition. Alternatively, when there are a plurality of corresponding groups, the grouping unit 17 may select one group at random.

  Next, the third condition will be described.

  The grouping unit 17 selects a group in which the desired traveling direction of the hall call is the same direction as a group that satisfies the third condition. That is, the grouping unit 17 includes at least one group of hall calls having the same desired traveling direction as the desired traveling direction of the predetermined hall call in the predetermined hall call that is the target of the grouping process. The predetermined hall call is assigned to any group.

  Here, when there are a plurality of corresponding groups, the grouping unit 17 finally sets the group having the longest predicted arrival time (CarYTJ) to the floor of the response machine as a group meeting the third condition. You can choose.

  Alternatively, when there are a plurality of corresponding groups, the grouping unit 17 may finally select the group having the shortest predicted arrival time (CarYTJ) as a group that satisfies the third condition. Alternatively, when there are a plurality of corresponding groups, the grouping unit 17 may finally select a group having the minimum / maximum number of people in the car of the response machine as a group meeting the third condition. The group in which the waiting time in the car in the car is minimum / maximum may be finally selected by the grouping unit 17 as a group meeting the third condition, or the longest among the hall calls constituting the group The grouping unit 17 may finally select the group to which the hall call having the longest / shortest elapsed time (HCTimeMax) belongs as a group meeting the third condition. Alternatively, when there are a plurality of corresponding groups, the grouping unit 17 may select one group at random.

  The grouping unit 17 may select a group to which the hall call belongs under a condition that combines all of the first to third conditions, and uses any one or more of the first to third conditions. Thus, the group to which the hall call belongs may be selected. For example, if the hall calls are grouped under the first condition, the second condition is also satisfied. Therefore, hall calls that could not be grouped under the first condition may be grouped under the second condition.

  After step ST2012, in step ST2013, the grouping unit 17 creates a new group for the hall call for which the group to which the group is assigned has not been determined in step ST2012. Then, the grouping unit 17 assigns the hall call to the created new group.

  When step ST201 in FIG. 14 (a series of flows shown in FIG. 15) is completed, the grouping unit 17 performs the process of step ST202. Specifically, the grouping unit 17 instructs the group notification device 4 to display a group symbol indicating the group determined to belong to the hall call in the process of step ST201.

  When receiving the instruction, the group notification device 4 displays the group to which the hall call belongs on the display in order to notify the passenger of the group to which the hall call belongs. For example, if a group is represented by an alphabet, an alphabet symbol such as “A” is displayed on the display as the group to which the hall call belongs.

  When a passenger registers a hall call with the call registration device 2, a group symbol indicating the group to which the hall call belongs is displayed on the group notification device 4, so that the passenger can store the group symbol. . When the passenger moves to the forecasting device 3, the combination of the group symbol and the response machine is displayed on the forecasting device 3 (see FIG. 16). Thereby, the passenger gets on the response machine notified by the forecasting device 3. Group symbols are not limited to alpha beds. It can be a number, a word, or a figure.

  When the display of the group symbol in step ST202 is completed, in step ST203, the extraction unit 13 selects a hall call group for reviewing the answering machine from the hall call groups held in the storage unit 16. select. Here, the selection method by the extraction unit 13 is the same as the method described in the first embodiment.

  In the first embodiment, the extraction unit 13 uses the elapsed time (HCTime) after each hall call is generated when calculating the review priority (PRT). However, when reviewing in units of groups as in the present embodiment, since there are a plurality of hall calls constituting the group, there are also a plurality of elapsed times (HCTime) held by the group.

  Therefore, in the present embodiment, when calculating the priority (PRT), the maximum value (HCTimeMax) among the elapsed times (HCTime) of all hall calls constituting the group may be used. Alternatively, an average value (HCTimeMin) of elapsed times (HCTimeMin) of all hall calls constituting the group may be used, or a minimum value (HCTimeMin) of elapsed times (HCTime) of all hall calls constituting the group May be used.

  In addition, the group where the number of hall calls that make up the group has increased compared to the time when the answering machine was reviewed last time, is the priority call weight group Wprt, and so on. It may be a larger value than the group.

  The process in step ST204 in the flowchart shown in FIG. 14 is the same as the process in step ST102 in the flowchart shown in FIG. The process in step ST205 in the flowchart shown in FIG. 14 is the same as the process in step ST103 in the flowchart shown in FIG. The process in step ST206 in the flowchart shown in FIG. 14 is the same as the process in step ST104 in the flowchart shown in FIG. The process in step ST207 in the flowchart shown in FIG. 14 is the same as the process in step ST105 in the flowchart shown in FIG. Furthermore, the process of step ST208 of the flowchart shown in FIG. 14 is the same as the process of step ST106 of the flowchart shown in FIG.

  Here, the parameter used in the calculation in each step of FIGS. 3 and 14 includes an elapsed time (HCTime) after each hall call is generated. When reviewing response machines for hall calls on a group basis, since there are a plurality of hall calls constituting the group, a plurality of elapsed times (HCTime) held by the group also exist.

  Therefore, in the present embodiment, the maximum value (HCTimeMax) in the elapsed time (HCTime) of all hall calls constituting the group may be used instead of the parameter (HCTime) described in the first embodiment. . Alternatively, instead of the parameter (HCTime) described in the first embodiment, in this embodiment, an average value (HCTimeMin) of elapsed times (HCTime) of all hall calls constituting the group may be used. You may utilize the minimum value (HCTimeMin) in the elapsed time (HCTime) of all the hall calls which comprise a group.

  In addition, a parameter used for calculation in each step of FIGS. 3 and 14 includes a landing waiting time (Twt). When reviewing answering machines for hall calls in groups, there are multiple hall calls that make up the group, and there are also multiple hall waiting times (Twt) for passengers in each hall call. There will also be a plurality of times (Twt).

  Therefore, in the present embodiment, the maximum value (TwtMax) in the hall waiting time (Twt) of all hall calls constituting the group may be used instead of the parameter (Twt) described in the first embodiment. good. Alternatively, in this embodiment, instead of the parameter (Twt) described in the first embodiment, the average value (TwtMin) of the hall waiting times (Twt) of all hall calls constituting the group may be used. The minimum value (TwtMin) in the hall waiting time (Twt) of all hall calls constituting the group may be used.

  In addition, the waiting time (Twi) in the car is a parameter used in the calculation in each step of FIGS. When reviewing answering machines for hall calls in groups, there are multiple hall calls that make up the group, and there are multiple waiting times (Twi) for passengers in each hall call. There are also a plurality of internal waiting times (Twi).

  Therefore, in the present embodiment, the maximum value (TwiMax) in the waiting time (TwiMax) in the car for all hall calls constituting the group is used instead of the parameter (Twi) described in the first embodiment. Also good. Alternatively, instead of the parameter (Twi) described in the first embodiment, in this embodiment, the average value (TwiMin) of the waiting time (Twi) in the car for all hall calls constituting the group may be used. The minimum value (TwiMin) in the waiting time (Twi) in the car for all hall calls constituting the group may be used.

  As described above, according to the present embodiment, hall calls are grouped, and the extraction unit 13 selects hall calls for reviewing response machines in units of groups. Accordingly, it is possible to review the response machines for the selected hall call (temporary determination processing by the temporary determination unit 14 and final determination processing by the final determination unit 15) on a group basis. Therefore, in the invention according to the present embodiment, there is a high possibility that the response machine for the hall call will be reviewed.

  In the present embodiment, the number of symbols displayed on the forecasting device 3 is reduced by grouping. Therefore, in the invention according to the present embodiment, it is possible to increase the display size of characters / symbols or the like to be displayed on the forecasting device 3, and to ensure visibility.

  In the present embodiment, the grouping unit 17 uses a predetermined condition to determine a group to which the hall call is not assigned, to select a group to which the hall call is assigned, and the like.

  Therefore, it is possible to assign a hall call to an appropriate group, prevent an answering machine from becoming an inappropriate car, and improve transportation efficiency.
