Description

  The present invention relates to an elevator operation control device and an elevator operation control method, and more particularly to a technique for reducing a waiting time of a user in a hall.

  Conventionally, as an elevator operation system, an operation system called a selective collective (hereinafter abbreviated as “selector collection”) has been widely adopted. SeleColle responds to calls in front of the moving direction of the car in order from the current position of the car in order from the current position of the car. This is an operation method that responds sequentially to each.

  In addition, a load detector is installed in the car to monitor the load on the car, and when the load exceeds the specified value, it is determined that the car is full and the passengers in the car get off. Even if there is a floor where hall calls in the same direction are input in the forward direction of the car, the time loss due to useless stops is reduced until the full state is resolved. The technology to make it known is widely known.

  In elevators that use SeleColle as a driving method, the waiting time of users waiting in the hall is a problem when applying the technology to pass the floor where the hall call is input when the car is full as described above It has been pointed out that it may become extremely long.

  For example, in a scene where the user who made the hall call in the upward direction is waiting on the second floor and the third floor, respectively, and the car is going up from the first floor, It is assumed that a user on the third floor makes a hall call before a user on the second floor, and that the registration order of hall calls is faster on the third floor than on the second floor. In this case, the car will first land on the second floor according to the SeleColle driving method, but as a result of a large number of passengers entering the car on the second floor, the car will become the destination floor for the car call. As long as the third floor is not designated, the car will pass through the third floor even though the third floor is registered as a hall call before the second floor.

  After that, when the car is full due to the response to the car call, the car responds sequentially to the hall call and car call in the upward direction, and all responses to the hall call and car call in the upward direction are completed. It switches to descending operation and responds sequentially to hall calls and car calls in the downward direction. Then, when all responses to the downward hall call and car call are completed, the operation is switched to the ascending operation again. At this time, if a new hall call is made by the user on the second floor, the car will first land on the second floor, and the user waiting on the second floor will get on the car first. Make it. Here, as described above, if a large number of passengers enter the car on the second floor and the car becomes full, the car will be used unless the third floor is designated as the destination floor for the car call. It will pass the 3rd floor again, and the waiting time of the user who is waiting on the 3rd floor will become extremely long.

  As a technique for reducing the waiting time of a user waiting in a hall, a technique described in Patent Document 1 is known. In the technique described in Patent Document 1, when a user waits in a hall and waits for a predetermined time or more in a hall, the floor on which the user is on standby Until the car arrives in the car, lower the threshold for determining the fullness to secure space in the car and ensure that users with longer waiting times get into the car. Yes.

JP-A-2005-330062

  However, in the technique described in Patent Document 1, the user can surely get into the car by lowering the fullness determination threshold when the waiting time of the user waiting in the hall reaches a predetermined time or more. Therefore, depending on the hall call status on the floor closer to the current position of the car than the floor on which the user is located, and on the empty space in the car, the floor on which the user is located There is a concern that it will take more time for the car to arrive and the waiting time of the user will be longer. In other words, there are hall calls in the same direction on many floors closer to the current position of the car than the floor where there is a user waiting for a predetermined time or more, and many users can only get in the car If there is enough space, the car will not be considered full, and after responding sequentially to hall calls on a number of floors close to the current position of the car, wait for a specified period of time. You will arrive at the floor where there are users. For this reason, a user who has already waited for a predetermined time or more may have to wait for a longer time until the car arrives, which may cause the user's standby time to become extremely long.

  The present invention has been made in view of the above, and is an elevator operation control that can effectively prevent the waiting time of a user waiting in a hall from becoming extremely long and improve the convenience of the elevator. An object is to provide a device and an elevator operation control method.

  In order to achieve the above object, an elevator operation control apparatus according to the present invention includes a hall call input by an elevator user operating a hall call button and a car call input by operating a car call button. Call registration means for registering, hall call registration order storage means for storing the registration order of the hall calls, the registered hall call and car call, the current position and moving direction of the car, and the car And a response floor determining means for determining a floor on which the next car is to be landed based on a user accommodation situation in the vehicle, and moving the car to the floor determined by the response floor determining means A control command output means for outputting a control command to cause a passing floor when the car passes through the floor to which the hall call is input without landing Passing floor storage means for storing the floor that has become the passing floor, and the response floor determining means, when the passing floor occurs in the previous round, in the next round, The floor with the earliest registration order of the hall call among the floors thus formed is determined as the floor on which the car is first landed.

  In order to achieve the above object, an elevator operation control method according to the present invention is input by operating a hall call and a car call button that are input by an elevator user operating a hall call button. A step of registering a car call, a step of storing the registration order of the hall call, the registered hall call and car call, the current position and moving direction of the car, and the user accommodation status in the car And a step of determining a floor on which the car is to be landed next, and a step of outputting a control command for moving the car to the floor determined as the floor to be ground next. When the car passes through the floor to which the hall call is input without landing, the step that stores the passing floor and the floor that has become the passing floor is stored. And in the step of determining the floor on which the next car is to be landed, if the passing floor occurs in the previous round, of the floors that became the passing floor in the next round The floor with the earliest registration order of the hall calls is determined as the floor on which the car is first landed.

  ADVANTAGE OF THE INVENTION According to this invention, it can prevent effectively that the waiting time of the user who waits in a hall becomes extremely long, and there exists an effect that the convenience of an elevator can be improved.

  Exemplary embodiments of an elevator operation control device and an elevator operation control method according to the present invention will be explained below in detail with reference to the accompanying drawings. In addition, the following embodiment shows an example of application of the present invention by way of example, and the present invention is not limited to this embodiment. In addition, the constituent elements of the embodiments described below can be appropriately changed to those that can be easily replaced by those skilled in the art or substantially the same.

(First embodiment)
FIG. 1 is a schematic configuration diagram showing an example of an elevator to which the present invention is applied. The elevator shown in FIG. 1 conveys a user by raising and lowering a car 1 between the first floor to the fifth floor of a building, and connects the car 1 and a counterweight 2 with a main rope 3. The main rope 3 is bridged over the driving sheave 4 and the deflector 5 connected to the electric motor M, and the car is utilized by using the frictional force between the driving sheave 4 and the main rope 3 that is rotationally driven by the electric motor M. This is a so-called traction type elevator that moves 1 up and down in a hoistway 6.

  Hall call buttons 7a to 7e are respectively installed in the landings (halls) H1 to H5 on the first floor to the fifth floor of the building. These hall call buttons 7a to 7e are buttons operated by the user to make hall calls with designated directions in the halls of each floor. Therefore, the hall call button 7a installed in the hall H1 on the first floor, which is the lowest floor of the building, is composed of only buttons for making hall calls in the upward direction because the direction of the user's destination is only upward. The hall call button 7e installed in the hall H5 on the 5th floor, which is the top floor of the building, is composed of only buttons for making a hall call in the downward direction because the user's destination is only in the downward direction. In addition, hall call buttons 7b to 7d installed in halls H2 to H4 on the second floor to the fourth floor, which are intermediate floors, are a button for making an upward hall call and a button for making a downward hall call. Are combined.

  Inside the car 1, a car call button 8 that is operated by a user who has entered the car 1 to make a car call is installed. The car call button 8 is configured by combining buttons corresponding to the first to fifth floors so that a user who enters the car 1 can make a car call specifying a destination floor. In addition, the car 1 is provided with a load sensor 9 that detects the load of the car 1 and a position detector 10 that detects the current position of the car 1. The position detector 10 includes, for example, a detector that detects the position of the car 1 based on a pulse output from the encoder according to the rotation of a roller that rolls along a guide rail (not shown). Any known detector for detecting the position can be used.

  A machine room 11 is provided in the upper part of the hoistway 6 where the car 1 moves up and down. An elevator control panel 12 is installed in the machine room 11 together with the electric motor M, the driving sheave 4, the deflector 5 and the like. The elevator control panel 12 controls the overall operation of the elevator as a whole. The hall call buttons 7a to 7e, the car call button 8, the load sensor 9, and the position detector 10 described above are connected to the elevator control panel 12. It is connected. The elevator operation control apparatus according to the present embodiment is realized as one function of the elevator control panel 12.

  FIG. 2 is a block diagram showing a functional configuration of the elevator operation control apparatus 100 according to the present embodiment. As shown in FIG. 2, the elevator operation control apparatus 100 according to the present embodiment includes a hall call button control unit 101, a car call button control unit 102, a call registration unit 103, a hall call registration order storage unit 104, and a full state determination. Unit 105, car position / direction recognition unit 106, response floor determination unit 107, control command output unit 108, and passing floor storage unit 109. These functional configurations are realized, for example, by a program stored in a program ROM or the like of the elevator control panel 12 being read out by an arithmetic unit (CPU) and loaded onto the main memory of the elevator control panel 12.

  When one of the hall call buttons 7a to 7e is operated by the user, the hall call button control unit 101 receives a hall call corresponding to the operated hall call button and outputs it to the call registration unit 103. By turning on the operated hall call button, control is performed to notify the user that the hall call has been registered. The hall call button control unit 101 controls to turn off the hall call button of the operated floor when the car 1 is landed on the floor where the hall call was made in response to the hall call. Do.

  When the car call button 8 is operated by a user who has entered the car 1, the car call button control unit 102 receives the car call and outputs it to the call registration unit 103 and turns on the car call button 8. Thus, control is performed to notify the user that the car call has been registered. In addition, the car call button control unit 102 performs control to turn off the car call button 8 when the car 1 reaches the floor designated by the car call in response to the car call.

  The call registration unit 103 registers the hall call each time a hall call corresponding to the user's button operation is input from the hall call button control unit 101, and the user's button operation from the car call button control unit 102. Each time a car call corresponding to is entered, this car call is registered. Here, the registration of the hall call and the car call refers to a process of storing the floor where the hall call was made and the direction of the call if it is a hall call, and the designated destination floor if it is a car call. The response to the call means that the car 1 is landed on the floor where the hall call was made or the destination floor designated by the car call. The hall call and the car call registered by the call registration unit 103 are deleted when a response is made to the call.

  The hall call registration order storage unit 104 stores the registration order of hall calls registered in the call registration unit 103, that is, the order in which hall calls in an unanswered state are input.

  The full state determination unit 105 compares the loading load of the car 1 detected by the load sensor 9 with a predetermined threshold based on the allowable loading load of the car 1, and the loading load of the car 1 sets the threshold value. It is determined whether or not the car 1 is full based on whether or not it has been exceeded.

  Based on the output from the position detector 10, the car position / direction recognizing unit 106 recognizes whether the car 1 is currently landing on the first floor to the fifth floor of the building, and immediately before The moving direction of the car 1 is recognized based on the positional relationship between the current landing floor and the current landing floor and the presence / absence of an unanswered call.

  The response floor determination unit 107 includes unanswered hall calls and car calls registered in the call registration unit 103, the current position and moving direction of the car 1 recognized by the car position / direction recognition unit 106, Based on the determination result by the state determination unit 105 (whether or not the car 1 is full), a floor (hereinafter referred to as a response floor) on which the car 1 is to be landed next is determined. Specifically, if the car 1 is not full, the response floor determination unit 107 checks the unanswered hall call and car call registered in the call registration unit 103, and The floor that is ahead of the current position in the direction of movement and that has the hall call entered in the same direction as the direction of movement of the car 1, or the floor designated as the destination floor of the car call Of these, the floor closest to the current position of the car 1 is determined as the response floor. Note that the floor on the front side in the moving direction of the car 1 is the floor above the current position when the car 1 is in the ascending operation, and the car 1 is in the descending operation. Is the floor below the current position. In addition, when the car 1 is full, the response floor determination unit 107 confirms the unanswered car call registered in the call registration unit 103 and determines the current position of the car 1 from the current position. The floor closest to the current position of the car 1 is determined as the response floor among the floors on the front side in the movement direction and designated as the destination floor of the car call.

  When the car 1 is full, even if the car 1 is landed on the floor where the hall call is entered, the user waiting in the hall cannot get into the car 1 A time loss due to a useless stop will occur. Therefore, when the car 1 is full, the response floor determining unit 107 preferentially responds to the car call and cancels the car 1 full state. Of the floors designated as call destination floors, the floor closest to the current position of the car 1 is determined as the response floor.

  At this time, a hall call in the same direction as the moving direction of the car 1 is input on the floor closer to the current position of the car 1 than the floor determined as the response floor, and this hall call is not answered. When registered in the call registration unit 103 as a hall call, the car 1 does not land on the floor and passes through the hall call without answering. An unanswered hall call on the floor to which the car 1 has passed will respond in the next lap, but before reaching the floor that passed in the previous lap in the next lap. When the car 1 becomes full again, the car 1 will pass through the floor again without being able to respond to the hall call on the floor in the next lap. As a result, the waiting time of the user who has called the hall on the floor becomes extremely long, which causes the convenience of the elevator to be significantly reduced.

  Therefore, the response floor determination unit 107, when there is a floor in which the car 1 has passed without responding to an unanswered hall call in the previous round (hereinafter referred to as a passing floor), the next round , The floor with the earliest registration order of hall calls is determined as the floor on which the car 1 is first landed (first response floor). . Specifically, the response floor determination unit 107, when a passing floor occurs in a certain lap, information indicating that the passing floor has occurred and the floor number of the floor that has become the passing floor, 109 is stored. Then, when the response floor determination unit 107 determines the first response floor in the next lap, the response floor determination unit 107 confirms the information stored in the passage floor storage unit 109 to generate a passage floor in the previous lap. If a passing floor has occurred in the previous round, that passing floor is determined as the first response floor. At this time, if a plurality of passing floors have occurred in the previous lap, the response floor determining unit 107 confirms the information stored in the hall call registration order storage unit 104 to check the plurality of passing floors. The registration order of the hall call at is determined, and the floor with the earliest registration order among the plurality of passing floors is determined as the first response floor. Note that the lap of the elevator refers to one unit of an operation cycle in which the car 1 is lifted and lowered. For example, after the car 1 is lifted, the driving direction is switched and lowered, and then the driving direction is changed again. This is the period of time before switching to rising.

  The control command output unit 108 outputs a control command for moving the car 1 to the response floor determined by the response floor determination unit 107. Specifically, when the response floor is determined by the response floor determination unit 107, the control command output unit 108 determines whether the car 1 is in accordance with the distance from the current position of the car 1 to the response floor. The acceleration and deceleration and the maximum speed of the car 1 are determined. Then, a movement pattern determined from the acceleration, deceleration, maximum speed, and movement distance of the car 1 is obtained, and the motor M is moved so that the car 1 moves from the current position to the response floor according to the movement pattern. Output control commands.

  As described above, the passing floor storage unit 109, when the car 1 passes through the floor to which the hall call is input without landing, the information that the passing floor has occurred and the floor that has become the passing floor. Memorize the floor number of the floor.

  FIG. 3 is a flowchart showing an outline of a series of processes by the elevator operation control apparatus 100 configured as described above. Hereinafter, the operation of the elevator operation control apparatus 100 according to the present embodiment will be briefly described along the flowchart of FIG.

  First, the call registration unit 103 registers a hall call input by the hall call button control unit 101 and a car call input by the car call button control unit 102 (step S1). The call registration unit 103 registers the hall call and the car call when the user operates any of the hall call buttons 7a to 7e or when the car call button 8 is operated by the user who has entered the car 1. This is a process executed whenever necessary.

  Next, the hall call registration order storage unit 104 stores the registration order of hall calls registered in the call registration unit 103 (step S2). The storage of the hall call registration order by the hall call registration order storage unit 104 is executed every time the hall call is registered by the call registration unit 103.

  Next, the response floor determination unit 107 detects the unanswered hall call and car call registered in the call registration unit 103 and the current position and moving direction of the car 1 recognized by the car position / direction recognition unit 106. Then, based on the determination result by the full state determination unit 105 (whether or not the car 1 is full), the response floor on which the car 1 is to be landed next is determined (step S3). The specific contents of the processing by the response floor determination unit 107 will be described later in detail.

  Next, the control command output unit 108 generates a control command for moving the car 1 to the floor determined by the response floor determination unit 107 and outputs the generated control command to the electric motor M. (Step S4).

  4 and 5 are flowcharts showing the details of the processing by the response floor determination unit 107 executed in step S3 of FIG. 3, and the processing when determining the first response floor of the car 1 in a certain lap. FIG. 5 shows the flow of processing when determining the response floor for the second and subsequent times in FIG. Here, since the process for determining the first response floor is related to the result of the process for determining the second and subsequent response floors in the previous round, first, in accordance with the flowchart of FIG. After the processing by the response floor determining unit 107 when determining the second and subsequent response floors is described, the response floor determining unit 107 when determining the first response floor according to the flowchart of FIG. Processing will be described.

  When the response floor determining unit 107 determines the second and subsequent response floors, as shown in FIG. 4, first, in step S101, the unanswered hall call and car registered in the call registration unit 103 are displayed. In step S102, the current position and moving direction of the car 1 recognized by the car position / direction recognition unit 106 are confirmed.

  Next, the response floor determination unit 107 checks whether or not the car 1 is determined to be full by the full state determination unit 105 in step S103. If it is determined that the car 1 is not full, the process proceeds to step S104. If the car 1 is determined to be full, the process proceeds to step S105.

  When it is determined that the car 1 is not full and the process proceeds to step S104, the response floor determination unit 107, in step S104, among the unanswered hall calls confirmed in step S101, the car confirmed in step S102. The floor to which the hall call in the same direction as the movement direction of 1 is input and the floor designated as the destination floor of the unanswered car call confirmed in step S101 are selected as response floor candidates. Then, from these candidates, the floor that is on the front side in the moving direction from the current position of the car 1 confirmed in step S102 and is closest to the current position of the car 1 is determined as the response floor. .

  On the other hand, when it is determined that the car 1 is full and the process proceeds to step S105, the response floor determination unit 107 determines the floor designated as the destination floor of the unanswered car call confirmed in step S101 in step S105. The floor is selected as a candidate for the response floor, and from among these candidates, the floor is on the front side in the moving direction from the current position of the car 1 confirmed in step S102 and is closest to the current position of the car 1. The floor is determined as the response floor.

  Next, in step S106, the response floor determination unit 107 determines that the floor designated as the destination floor of the unanswered car call in step S105 is the response floor, so that an unanswered hall call is input. It is determined whether any of the floors that have been used is a passing floor through which the car 1 passes without landing. If the response floor determination unit 107 determines that any of the floors to which an unanswered hall call has been input has become a passing floor, in step S107, information indicating that a passing floor has occurred; A process of storing the floor number of the floor that has become the passing floor in the passing floor storage unit 109 is performed.

  The process shown in the flowchart of FIG. 4 described above is to determine the response floor until the response to all calls except for hall calls on the passing floor is completed in one lap and transition to the next lap. It is repeatedly executed by the unit 107. Then, when proceeding to the next lap, the response floor determination unit 107 executes the processing shown in the flowchart of FIG. 5 to determine the first response floor, and thereafter repeats the processing shown in the flowchart of FIG. 4 again. Execute.

  When determining the first response floor, the response floor determination unit 107 first confirms the information stored in the passing floor storage unit 109 in step S201 as shown in FIG. It is determined whether or not there is a passing floor. If it is determined that a passing floor has not occurred in the previous round, the process proceeds to step S202. If it is determined that a passing floor has occurred in the previous round, the process proceeds to step S205.

  If it is determined that no passing floor has been generated in the previous round and the process proceeds to step S202, the response floor determination unit 107 determines that the unanswered hall call and car registered in the call registration unit 103 in step S202. In step S203, the current position and moving direction of the car 1 recognized by the car position / direction recognition unit 106 are checked.

  Next, in step S204, the response floor determination unit 107 receives the hall call in the same direction as the moving direction of the car 1 confirmed in step S203 among the unanswered hall calls confirmed in step S202. The floor and the floor designated as the destination floor of the unanswered car call confirmed in step S202 are selected as response floor candidates. Of these candidates, the floor that is the floor ahead of the current position of the car 1 confirmed in step S203 in the movement direction and closest to the current position of the car 1 is set as the first response floor. decide.

  On the other hand, if it is determined in step S201 that a passing floor has occurred in the previous round and the process proceeds to step S205, the response floor determination unit 107 generates a plurality of passing floors in the previous round in step S205. Check if it is. If there is one passing floor generated in the previous lap, the process proceeds to step S206. If a plurality of passing floors have occurred in the previous lap, the process proceeds to step S207.

  When it is determined that the number of passing floors generated in the previous round is one and the process proceeds to step S206, the response floor determination unit 107 determines the passing floor as the first response floor in step S206.

  On the other hand, if it is determined that a plurality of passing floors have occurred in the previous round and the process proceeds to step S207, the response floor determination unit 107 is stored in the hall call registration order storage unit 104 in step S207. The hall call registration order information is confirmed, and the floor having the earliest hall call registration order is identified from among the plurality of passing floors. In step S208, the response floor determination unit 107 determines the floor with the earliest registration order of the hall call identified in step S207 as the first response floor.

  Next, in step S209, the response floor determination unit 107 determines whether or not a new passing floor is generated by determining the passing floor of the previous round in step S206 or step S208 as the first response floor. . If the response floor determination unit 107 determines that a new passage floor is generated, the response floor determination unit 107 obtains information indicating that a passage floor has occurred and the floor number of the floor that has become the passage floor in step S210. , Processing to be stored in the passing floor storage unit 109 is performed.

  Thereafter, the motor M is driven and controlled in accordance with the control command output from the control command output unit 108, and when the car 1 reaches the first response floor, the response floor determination unit 107 includes the passing floor in the lap. The processing shown in the flowchart of FIG. 4 is repeatedly executed until the response to all calls except for the hall call is completed until the next lap is started. And if it transfers to the next round, the response floor determination part 107 will perform the process shown by the flowchart of FIG. 5 again, and will determine the first response floor in the next round.

  As described above in detail with specific examples, according to the elevator operation control apparatus 100 according to the present embodiment, a passing floor has occurred because the car 1 has become full in the previous lap. In the case of the next lap, the passing floor in the previous lap is determined as the first response floor, especially when multiple passing floors occur in the previous lap. Of the floors, the floor with the earliest registration order of hall calls is determined as the first response floor of the next lap, and the car 1 is preferentially landed. Therefore, it is possible to effectively prevent the waiting time of the user waiting in the hall from becoming extremely long, and the convenience of the elevator can be improved.

<Modification>
In the elevator operation control apparatus 100 described above, the full state determination unit 105 compares the loaded load of the car 1 detected by the load sensor 9 with a predetermined threshold value to determine whether the car 1 is full. Is determined. However, for example, when a user using a wheelchair gets into the car 1 or when a user with a large load gets into the car 1, the loading load of the car 1 is less than the threshold. However, there may be a case where there is no space for a new user to enter the car 1. In such a case, it is desirable to determine that the car 1 is full.

  Therefore, as schematically shown in FIG. 6, a detector 13 for detecting an empty space in the car 1 is installed in the car 1, and a detection signal of the detector 13 is sent to the full state determination unit 105. The full state determination unit 105 is configured to input the load based on the loading load of the car 1 detected by the load sensor 9 and the presence or absence of an empty space in the car 1 detected by the detector 13. It may be determined whether the car 1 is full. Here, as the detector 13 for detecting an empty space in the car 1, a known sensor capable of detecting a space, such as a camera or an infrared sensor, can be used.

  As described above, the detector 13 for detecting the empty space in the car 1 is provided, and the full state determination unit 105 detects the loaded load of the car 1 detected by the load sensor 9 and the detector 13. When it is determined whether or not the car 1 is full based on whether or not there is an empty space in the car 1 to be used, the full state of the car 1 is more accurately determined. Thus, the time loss due to the useless stop of the car 1 can be further effectively reduced, and the convenience of the elevator can be further improved.

(Second Embodiment)
Next, an elevator operation control apparatus according to the second embodiment will be described. FIG. 7 is a block diagram showing a functional configuration of the elevator operation control apparatus 200 according to the present embodiment. As shown in FIG. 7, the elevator operation control apparatus 200 according to the present embodiment adds a waiting number predicting unit 201 to the configuration of the elevator operation control apparatus 100 according to the first embodiment (see FIG. 2). The specific contents of the process of determining the response floor in the response floor determination unit 107 are different from those of the first embodiment. In the following, the description common to the first embodiment will be omitted, and only the characteristic part of the present embodiment will be described.

  The waiting number predicting unit 201 predicts the number of users waiting on the floor where the hall call is input. Specifically, the waiting time prediction unit 201 uses, for example, a table describing the relationship between the elapsed time since the hall call registration and the number of users waiting in the hall, and the elapsed time since the actual hall call. Predict the number of users according to The table used for predicting the waiting number is the elapsed time from the previous hall call registration to the hall call response and the number of users who have entered the car 1 by the hall call response (estimated from the detection value of the load sensor 9). ) And tabulated for each floor. When a hall call is input on a certain floor, the waiting number predicting unit 201 measures an elapsed time after the hall call is registered in the call registration unit 103, and calculates the number of persons corresponding to the elapsed time from the table. Specifically, the number of users waiting on the floor where the hall call is input is predicted. It is desirable that the table used for predicting the number of waiting persons is updated as needed using the information every time a response to the hall call is made.

  In the elevator operation control apparatus 200 according to the present embodiment, the response floor determination unit 107 is recognized by the unanswered hall call and car call registered in the call registration unit 103 and the car position / direction recognition unit 106. In addition to the current position and moving direction of the car 1 and the determination result by the full state determination unit 105 (whether the car 1 is full), it is stored in the hall call registration order storage unit 104 The response floor of the car 1 is determined using the information and information on the number of users waiting in the hall predicted by the waiting number prediction unit 201. That is, the response floor determination unit 107 determines the response floor when the car 1 is full, as in the first embodiment, but when the car 1 is not full. The response floor determined in the same manner as in the first embodiment is a floor to which a hall call is input, and when a user waiting on the floor gets into the car 1, the car 1 is full. If there is another floor whose hall call registration order is earlier than that floor, the floor is used as the passing floor and the floor call registration order is earlier than that floor. The response floor is preferentially determined.

  FIG. 8 is a flowchart showing details of processing executed by the response floor determination unit 107 in the elevator operation control apparatus 200 according to the present embodiment, and determines response floors for the second and subsequent times in one lap. The process at the time is shown. Hereinafter, the flow of processing executed by the response floor determination unit 107 will be described with reference to the flowchart of FIG. Note that the process of determining the first response floor in one lap is the same as the process described in the first embodiment (see FIG. 5), and thus the description thereof is omitted here.

  The response floor determination unit 107 first confirms the unanswered hall call and car call registered in the call registration unit 103 in step S301, and is recognized by the car position / direction recognition unit 106 in step S302. Check the current position and moving direction of the car 1.

  Next, the response floor determination unit 107 confirms whether or not the car 1 is determined to be full by the full state determination unit 105 in step S303. If it is determined that the car 1 is not full, the process proceeds to step S304, and if the car 1 is determined to be full, the process proceeds to step S311.

  If it is determined that the car 1 is not full and the process proceeds to step S304, the response floor determination unit 107 receives an unanswered hall call in the same direction as the moving direction of the car 1 in step S304. Of the floor and the floor designated as the destination floor of the unanswered car call, it is the floor ahead of the current position of the car 1 in the moving direction and closest to the current position of the car 1 The floor is selected as a response floor candidate.

  Next, in step S305, the response floor determination unit 107 determines whether the floor selected as a response floor candidate in step S304 is a floor to which an unanswered hall call is input, or has not been answered. It is determined whether the floor is designated as the destination floor of the car call. If the floor selected as the response floor candidate is the floor designated as the destination floor of the unanswered car call, the process proceeds to step S310, and the floor selected as the response floor candidate is selected. Determine as response floor.

  On the other hand, when the floor selected as a candidate for the response floor is a floor to which an unanswered hall call has been input, the response floor determination unit 107 receives the response from the waiting number prediction unit 201 in step S306. By using the information, it is determined whether or not the car 1 is full when the user waiting on the floor selected as a candidate for the response floor gets into the car 1. If it is determined that the car 1 is not full, the process proceeds to step S310, and the floor selected as the response floor candidate is determined as the response floor.

  On the other hand, if it is determined that when the user enters the car 1 on the floor selected as a candidate for the response floor, the car 1 becomes full, the response floor determination unit 107 calls the hall call in step S307. The information on the registration order of hall calls stored in the registration order storage unit 104 is confirmed, and the registration order is higher than the hall call on the floor selected as a candidate for the response floor on the front side in the moving direction of the car 1. It is determined whether there is a floor to which an early hall call in the same direction is input. If there is no such floor, the process proceeds to step S310, and the floor selected as the response floor candidate is determined as the response floor.

  On the other hand, when there is a floor to which a hall call having a registration order earlier than the hall call at the floor selected as the response floor candidate is input, the response floor determination unit 107 responds in step S308. The floor selected as the floor candidate is determined as the passing floor, and in step S309, information indicating that the passing floor has occurred and the floor number of the floor that has become the passing floor are stored in the passing floor storage unit 109. Process to memorize. Then, returning to step S304, a new response floor candidate is selected from other floors excluding the floor determined as the passing floor. Then, by repeatedly executing the processing from step S305 described above, the response floor is determined while preventing the floor in which the hall call registration order is early from becoming a passing floor.

  In addition, when the car 1 is determined to be full in step S303 and the process proceeds to step S311, the response floor determination unit 107 is designated as the destination floor of the unanswered car call confirmed in step S301 in step S311. From among the existing floors, the floor that is on the front side in the moving direction from the current position of the car 1 confirmed in step S302 and is closest to the current position of the car 1 is determined as the response floor.

  Next, in step S312, the response floor determination unit 107 determines that the floor designated as the destination floor of the unanswered car call in step S311 is the response floor, so that an unanswered hall call is input. It is determined whether any of the floors that have been used is a passing floor through which the car 1 passes without landing. If the response floor determination unit 107 determines that any of the floors to which an unanswered hall call has been input has become a passing floor, in step S313, information indicating that a passing floor has occurred; A process of storing the floor number of the floor that has become the passing floor in the passing floor storage unit 109 is performed.

  The process shown in the flowchart of FIG. 8 described above is to determine the response floor until the response to all calls except the hall call on the passing floor is completed and the process proceeds to the next lap in one lap. It is repeatedly executed by the unit 107. Then, when proceeding to the next lap, the response floor determination unit 107 executes the processing shown in the flowchart of FIG. 5 to determine the first response floor, as described in the first embodiment. Thereafter, the processing shown in the flowchart of FIG. 8 is repeated.

  As described above in detail with specific examples, according to the elevator operation control apparatus 200 according to the present embodiment, as in the elevator operation control apparatus 100 according to the first embodiment, When a passing floor occurs because the car 1 is full in the lap, the passing floor in the previous lap is determined as the first response floor in the next lap. If multiple passing floors occur during a lap, the floor with the earliest registration order of hall calls is determined as the first response floor of the next lap among these multiple passing floors, and the car 1 I try to give it a priority. Therefore, it is possible to effectively prevent the waiting time of the user waiting in the hall from becoming extremely long, and the convenience of the elevator can be improved.

  Particularly, in the elevator operation control apparatus 200 according to the present embodiment, when the user enters the car 1 at a floor where the registration order of hall calls is slow, the car 1 becomes full. If it is predicted that the floor with the early registration order will be the passing floor, the floor with the late hall call registration order will be the passing floor, and the car 1 will be placed on the floor with the early hall call registration order. Since the floor is preferentially landed, the waiting time of the user waiting in the hall can be leveled, and the convenience of the elevator can be further improved.

<Modification>
In the elevator operation control apparatus 200 described above, the waiting number predicting unit 201 predicts the waiting number using a table that describes the relationship between the elapsed time since the hall call registration and the number of users waiting in the hall. ing. However, the table used for predicting the number of waiting persons shows the elapsed time from the previous hall call registration to the hall call response and the number of users who have entered the car 1 by the hall call response for each floor. Therefore, the prediction error tends to be relatively large.

  Therefore, as schematically shown in FIG. 9, a combination of a plurality of buttons for designating the destination floor is used as the hall call buttons 7a to 7e installed in the halls of the respective floors. For each floor, the number of waiting persons may be predicted by counting the number of operations of the hall call buttons 7a to 7e between the hall call and the response. In other words, if you use a combination of multiple buttons to specify the destination floor as the hall call button, even if there is another user who is waiting for the hall call first, you will arrive at the hall later The operated user operates the button corresponding to the destination floor, and the number of times the button is operated substantially matches the number of waiting persons. Therefore, the waiting number predicting unit 201 can accurately predict the waiting number on each floor by counting the hall calling buttons 7a to 7e on each floor received by the hall calling button control unit 101.

  As described above, a combination of a plurality of buttons for designating the destination floor is used as the hall call buttons 7a to 7e, and the waiting number predicting unit 201 counts the number of operations of the hall call buttons 7a to 7e. Predicting the number of people waiting on each floor makes it possible to accurately predict the number of people waiting on each floor, so it is better to determine whether a floor with a slower hall call registration order is a passing floor. Thus, the convenience of the elevator can be further improved.

  As described above, the elevator operation control device and the elevator operation control method according to the present invention are useful as a technique for reducing the waiting time of a user waiting in a hall.
