Description

  Embodiments described herein relate generally to an elevator group management control device and an elevator group management control method.

  Conventionally, when calling an elevator car from a landing, an up / down call registration device is used. In this vertical call registration device, only the vertical direction can be selected at the landing, and each destination floor is selected from the operation panel in the car.

  Recently, there is a destination control system (DCS) that can register a destination floor of an elevator from a destination call registration device installed at a landing. When the destination floor is registered at DCS, the most suitable car can be assigned from each unit, which contributes to the improvement of transportation efficiency.

  On the other hand, due to cost and user habituation problems, an up / down call registration device may also be required. As a result, the destination call registration device is used on floors with high traffic demand such as the lobby floor, and other floors are used. Then, there is a composite case in which an up / down call registration device is used. A mixture of the floor where the destination call registration device is installed and the floor where the up / down call registration device is installed is also called “hybrid DCS”.

JP 2013-216423 A JP, 2014-152032, A

  In a DCS configured only by destination calls, since the user's destination floor is known before answering the call, efficient vehicle allocation is possible, and it is possible to manage boarding / exiting of all users. For this reason, the user cannot get into the responding car.

  However, the hybrid DCS cannot completely grasp the number of users getting in from the floor registered by the up / down call registration device. For this reason, if the car that is scheduled to respond to the destination call first responds to the up / down call, the car becomes full on the up / down call registration floor, and the user cannot get over when responding to the destination call There was a problem that there was a case.

  In view of the above circumstances, an embodiment of the present invention aims to provide an elevator group management control device and an elevator group management control method capable of improving convenience without leaving a user even in a hybrid DCS. .

  The first mode for achieving the above object is that each unit performs call registration in a building in which a destination call registration device for registering a destination floor and an upper and lower call registration device for registering the upper and lower floor directions are mixed. An elevator group management control device to be allocated, a destination call receiving unit that acquires a floor registered by the destination call registration device and a user's destination floor, and a floor registered by the upper and lower call registration device Up and down call reception unit that acquires direction information indicating which direction the user is going up and down, and call registration information received by the upper and lower call reception unit or destination call reception unit, and the current car Obtain the position and load in the car, calculate whether it is a car that can be assigned, obtain candidate cars that are candidates for assignment, and further consider the expected arrival time to the landing call, etc. Is short The allocation candidate unit evaluation unit for calculating the evaluation value so as to improve the evaluation of the car, and the registration information of the landing call is acquired, and the destination call is obtained for the evaluation value calculated by the allocation candidate unit evaluation unit. In the case of registration, the evaluation value of the corresponding car is lowered, the assignment to the car that is scheduled to respond to the up and down calls in the direction toward the destination call registration floor is suppressed, and the direction toward the destination call registration floor If an up-and-down call is registered, the evaluation value of the corresponding car is lowered, and the registered floor of the new up-and-down call is already scheduled to respond to the destination call and arrives before the destination call registration floor. A call combination evaluation unit that suppresses allocation to a certain car and an evaluation value obtained by modifying the evaluation value calculated from the call combination evaluation unit based on the response time to the hall call of each car. Get in the basket In a elevator group management control apparatus comprising: an allocation Unit determining unit, the determining the priority to assignment No. machine best car evaluation value.

  The second mode is an elevator group management control device for allocating call registration in each building in a building where a destination call registration device for registering a destination floor and an upper and lower call registration device for registering upper and lower floor directions are mixed. An elevator group management control method to be executed, which obtains the floor registered by the destination call registration device and the user's target floor, and moves the floor and the user registered by the upper / lower call registration device up or down. Direction information that indicates whether the vehicle is heading in the direction of the car, and the call registration information received by the up / down call reception part or the destination call reception part, and the current car position and the load in the car are obtained and assigned. The number of candidate cars that can be assigned is calculated by calculating whether the car is possible, and the estimated arrival time at the hall call is taken into consideration, so that the evaluation of the car with a short estimated arrival time is improved. value Perform calculation, obtain registration information for the hall call, and if a destination call is registered for the calculated evaluation value, lower the evaluation value of the corresponding car and head to the destination call registration floor already If the up / down call in the direction toward the destination call registration floor is registered while the allocation to the car that is scheduled to respond to the up / down call in the direction is registered, the evaluation value of the corresponding car is lowered and the destination call has already been reduced. Suppress the allocation to the car at the location where the new floor call registration floor arrives earlier than the destination call registration floor, and calculate based on the response time to the landing call of each car The elevator group management control method is characterized in that an evaluation value obtained by correcting an evaluation value obtained is obtained, and an assigned car is determined in preference to a car having the best evaluation value among the cars. .

<Concept of embodiment in elevator group management control system according to the present invention>
First, the concept of group management control in the embodiment based on the hybrid DCS will be described with reference to FIGS.

  As shown in each figure, the floor configuration of the embodiment assumes a building consisting of the B1 floor and the 1st to 7th floors, the second floor is the destination call registration floor where the destination call registration device is installed, and the other floors It is assumed that the floor is the upper / lower call registration floor where the upper / lower call registration device is installed. In the embodiment, the hybrid DCS presents a call assignment method when there are service floors above and below the destination call registration floor (when the destination call registration floor is not the upper and lower floors). In each figure, a black triangle indicates a call that is an assignment suppression target (cannot be assigned), and a white triangle indicates a call that is not an assignment suppression target (can be assigned).

  As shown in FIG. 1 (A), the destination floor call registration is performed on the second floor, which is the floor (destination call registration floor) where the destination call registration device is installed, for the units to which destination calls have already been assigned. No new up / down call is assigned in the direction toward the second floor, which is the floor. For example, when a downward call (DN direction) is generated from the upper floor than the second floor, a call to a machine to which a destination call has already been assigned is not assigned. In FIG. 1A, the allocation of up and down calls toward the destination floor is suppressed for the destination call allocation machines in the allocation suppression ranges A1 and A2.

As shown in FIG. 1B, a new destination call in the direction toward the destination floor call registration floor (the second floor) is not assigned to a machine to which an up / down call has already been assigned. For example, if the up and down calls from the upper floor (7th to 3rd floors) above the second floor are already assigned, the destination call of the 7th to 3rd floors going to the second floor is assigned the second floor destination call. Calls to existing units will not be assigned. In FIG. 1B, destination call assignment is suppressed for the upper and lower call assignment units in the assignment suppression ranges B1 and B2. In the example shown in FIG. 2, the destination call on the second floor is registered in the initial state. It has become. In this state, a situation is shown in which a first floor UP or a fifth floor DN up / down call is newly registered. Unit 1 is traveling toward the 6th floor, which is the destination floor, and Unit 4 is traveling toward the B1 floor, which is the destination floor. The first floor UP should be assigned to Unit 2 located near the B1 floor considering only the estimated arrival time, but since Unit 2 is assigned a destination call from the second floor, the assignment is suppressed, Next, allocation is made to Unit 4 with a short estimated arrival time. At this time, the destination call from the second floor is assigned to the No. 3 machine, but since the No. 3 responds to the first floor UP after the destination call response, the assignment to the No. 3 machine is not suppressed. The fifth floor DN call is the same except that the direction of the car is different.

In the example shown in FIG. 3, the upper and lower calls on the first floor and the fifth floor are registered in the initial state.
Unit 1 is traveling toward the 6th floor, which is the destination floor, and Unit 4 is traveling toward the B1 floor, which is the destination floor. In this state, a destination call is newly registered on the second floor. At this time, since No. 2 and No. 3 are assigned up and down calls to the destination call registration floor, the assignment of destination calls generated on the second floor is suppressed.

  Next, each embodiment based on the way of thinking of the group management control as described above will be described.

<First Embodiment>
As shown in FIG. 1, the elevator group management control system 1 </ b> A includes an elevator control device 2, an elevator group management control device 3 </ b> A, a destination call registration device 4, and an up / down call registration device 5.

  The elevator control device 2 controls each unit individually, and is composed of a first unit control unit 21, a second unit control unit 22, ..., an nth unit control unit 2n.

  The destination call registration device 4 is a device that performs destination call registration for a user to select a floor that the user wants to go to at the landing, and is assumed to be installed on the second floor in the embodiment.

  The up / down call registration device 5 is a device for selecting which direction the user goes up and down at the landing on each floor, and is installed on each floor other than the second floor in the embodiment.

  The elevator group management control device 3A includes an elevator information management unit 31, an elevator car information setting unit 32, an up / down call reception unit 33, a destination call reception unit 34, an allocation candidate car evaluation unit 35, and a call combination evaluation unit 36. And an assigned number machine determination unit 37 and an elevator control command output unit 38.

  The elevator information management unit 31 provides information such as the position and direction of the car, the occupancy rate in the car, the car call registration status, the hall call registration status, and the number of passengers scheduled at the destination call response from each car. Is acquired, information specific to the elevator system is acquired from the elevator unit information setting unit 32, and information is exchanged in response to a request.

  The elevator unit information setting unit 32 is specific to each elevator system, which is mainly determined at the design stage, such as the elevator floor, the number of passengers in each car, what operating specifications are present, and the setting values for each operating specification. Record unit information.

  The up / down call accepting unit 33 acquires the direction in which the user is registered with the floor registered by the up / down call registration device.

  The destination call accepting unit 34 acquires the floor registered by the destination call registration device and the user's destination floor.

  The allocation candidate machine evaluation unit 35 acquires the call registration information received by the up / down call reception unit or the destination call reception unit, acquires the car position, the load in the car, etc. from the elevator information management unit 31, In order to calculate whether the car can be assigned, obtain candidate cars for assignment, and to determine which car should be assigned a hall call, consider the estimated arrival time to the hall call, etc. The evaluation value is calculated so that the evaluation of the car having a short predicted arrival time is improved.

  The call combination evaluation unit 36 acquires the registration information of the hall call from the elevator information management unit, acquires the information of the hall call registered from the upper and lower call reception unit 33 or the destination call reception unit 34, and is assigned candidate number evaluation unit In the case where a destination call is registered for the evaluation value calculated in 35, in order to suppress allocation to the car that is scheduled to respond to the call of the up / down call registration device 5 in the direction toward the destination call registration floor. If the up / down call in the direction toward the destination call registration floor is registered, the registered floor of the new up / down call is already scheduled to respond to the destination call and the registration floor of the destination call registration floor In order to suppress the allocation to the car in the position that arrives first, the evaluation value of the corresponding car is deteriorated.

  The assigned number machine determination unit 37 acquires an evaluation value obtained by correcting the evaluation value calculated based on the response time to the hall call, etc. of each car from the call combination evaluation unit 41. The assignment number is determined so that the assignment is given priority over the car with the best evaluation value.

  The elevator control command output unit 38 obtains information on which car is assigned to the registered hall call from the assigned car determination unit 37, and responds to the hall call assignment to the single control unit of each car. Output a simple command.

  Next, the processing procedure of 1st Embodiment is demonstrated using the flowchart of FIG. 5, FIG.

  FIG. 5 shows a processing procedure when a destination call is registered, and FIG. 6 shows a processing procedure when an up / down call is registered.

  In FIG. 5, when a destination call is registered (step S1), a predicted arrival time is calculated, and evaluation based on the predicted arrival time is performed (step S2). If the car with a good evaluation result is the top / bottom call assignment car (step S3 YES), it is determined whether the car position is above the destination call registration floor (the second floor in this example) (step S4). If the car position is the floor above the destination call registration floor (step S4 YES) and the DN call is assigned to the floor up to the destination call registration floor (step S5 YES), the evaluation value of the corresponding car is set. A bad setting is made (step S7). In addition, when the car position is the floor below the destination call registration floor (step S4 NO), but the UP call is assigned to the floor up to the destination call registration floor (step S6 YES), the corresponding car is evaluated. A bad value is set (step S7).

  On the other hand, if the unit with the good evaluation result is not the top / bottom call allocation unit (step S3NO), the determination at step S5 indicates that the DN call is not allocated on the floor up to the destination call registration floor (step S5NO), or step S6. If the UP call is not assigned in the floor up to the destination call registration floor (NO in step S6), the evaluation value is compared with other units and assigned to a unit having a good evaluation value (step S8). , S9).

  On the other hand, in the process when the up / down call shown in FIG. 6 is registered, when the up / down call is registered (step S11), the predicted arrival time is calculated, and the evaluation based on the predicted arrival time is performed (step S12). . If the machine having a good evaluation result is the destination call assigned car (step S13 YES), it is determined whether the upper and lower call registration floors are higher than the destination call registration floor (the second floor in this example) (step S13). S14). If the up / down call registration floor is a floor above the destination call registration floor (step S14 YES) and the registered up / down call is a DN call (step S15 YES), the evaluation value of the corresponding machine is set poorly (step S15). S17). Also, when the up / down call registration floor is a floor below the destination call registration floor (NO in step S14), but the registered up / down call is an UP call (YES in step S16), the evaluation value of the corresponding machine is set poorly. (Step S17).

  On the other hand, if the machine with the good evaluation result is not the destination call assigned car (step S13 NO), it is registered in the determination in step S15, if the registered up / down call is an UP call (step S15 NO), or in the determination in step S16. If the up / down call is a DN call (NO in step S16), the evaluation value is compared with other units and assigned to a unit having a good evaluation value (steps S18 and S19).

  As described above, in the first embodiment, in addition to the conventional group management control method, the call combination evaluation unit 36 uses each car for the assigned evaluation value of each car created by the assignment candidate car evaluation unit 35. If it is determined from the registration status of the hall call that the number is assigned, the process of making the evaluation worse is performed.

  As described above, according to the first embodiment, by suppressing the allocation by the combination of calls, the destination call answering machine becomes full before responding to the destination call, and the destination call user can get over. It is possible to eliminate the unloading at the destination call registration floor by avoiding the state of not being present.

Second Embodiment
As shown in FIG. 7, in the elevator group management control system 1B of the second embodiment, a load recording unit 39 is added to the elevator group management control apparatus 3B of the first embodiment to configure the elevator group management control apparatus 3B. It is a thing. And in 2nd Embodiment, based on the record of the increase amount of the load in a cage | basket | car at the time of responding to an up-and-down call in the past, the current load in a cage | basket | car, and the boarding number of persons in a destination call registration floor, It is determined whether or not response is possible, and it is determined whether or not to perform allocation suppression.

In the first embodiment, a method of suppressing allocation of up / down calls having a specific direction to a destination call answering machine has been described. However, when the total number of users is small, there may be a case where no leftover occurs even if the destination call is answered after the up / down call response. Even in this case, the purpose of suppressing the occurrence of unloading can be achieved, but the operation efficiency is deteriorated.
In order to solve this, the amount of increase in the car load when responding to an up / down call is predicted, and even when responding to an up / down call, if it is determined that all destination call users can board, Outputs up / down call assignments. The method of judgment is to add the increase in the load in the car at the time of the up / down call response on the corresponding floor in the past to the load in the car at that time, and then even if the number of passengers scheduled to get on the destination call registration floor gets on Calculate whether the full load is not exceeded, and if not, respond to the up / down call.

  The load recording unit 39 inputs the load amount data in each car from the machine control devices 21, 22, 2n, and records the load increase of the car when each car responds to the up and down calls.

  The call combination evaluation unit 40, when the up / down call is registered, the information on the up / down call registered from the up / down call reception unit 33, and the load that increases when the up / down call registered from the load recording unit 39 is responded. The increase load when responding to the destination call from the elevator information management unit 31 and the full load of the car are acquired, and the full load is not exceeded even if the car scheduled for the destination call response responds to the registered vertical call If it exceeds, the evaluation value will be worsened.

  Next, the processing procedure of the second embodiment will be described with reference to the flowchart of FIG. In FIG. 8, the same steps as those in FIG. 6 are denoted by the same step numbers.

  In the process shown in FIG. 6, if the up / down call registration floor is a floor above the destination call registration floor (step S14 YES), and the registered up / down call is a DN call (step S15 YES), the evaluation of the corresponding machine is performed. A bad value is set (step S17). Also, when the up / down call registration floor is a floor below the destination call registration floor (NO in step S14), but the registered up / down call is an UP call (YES in step S16), the evaluation value of the corresponding machine is set poorly. (Step S17).

  In the process when the up / down call shown in FIG. 8 is registered, the load recorded in the load recording unit 39 is checked before proceeding to the process of step S17 (step S21). When the load exceeds the allowable range (step S22 YES), the evaluation value of the corresponding car is set worse (step S17). If the load does not exceed the permissible range (NO in step S22), the process proceeds to step S18, where the evaluation value is compared with other units and assigned to a unit having a good evaluation value (steps S18 and S19).

  As described above, according to the second embodiment, when it can be determined from the past records that the number of people to be boarded is small, by responding to the up / down call, the destination call response is suppressed while suppressing the deterioration of the operation efficiency. It is possible to prevent the occurrence of unloading of time. Therefore, for example, when assignment is performed, if the number of passengers is small relative to the full load, it is possible to prevent a situation where operating efficiency is deteriorated by operating multiple units where one vehicle is sufficient. Is possible.

<Third Embodiment>
As shown in FIG. 9, the elevator group management control device 3 </ b> C of the third embodiment adds a number counting device 6 that counts the number of users on the landing in addition to the configuration of the first embodiment.

  The number-of-people counting device 6 is a device for acquiring the number of elevator users based on image signals taken by a hall camera or the like. From there, it is estimated how many people will get in the car, and even if it responds to the corresponding floor, it is judged whether it can respond to the destination call thereafter, and the allocation is suppressed.

  The call combination evaluation unit 41 acquires the number of people on the upper and lower call registration floors from the number counting device 6, predicts how many people will get in, and determines whether or not to respond to the upper and lower calls. And if the destination call answering car is responding to the registered up / down call, and the users on the floor where the up / down call is registered, all of the users have boarded, will the specified number of people (full load) be exceeded? The evaluation value is deteriorated only when it is confirmed and exceeded. Even if the car responds to the destination call, the evaluation value is not corrected when it is predicted that there will be no unloading even after responding to the destination call after responding to the up / down call.

  Next, the processing procedure will be described with reference to the flowchart of FIG.

  In the process when the up / down call shown in FIG. 10 is registered, the number of people in the hall (the landing) is checked before proceeding to the process of step S17 (step S31). If the number of persons exceeds the predetermined number (step S32 YES), the evaluation value of the corresponding machine is set poorly (step S17). If the number of people at the landing does not exceed the predetermined number (step S32 NO), the process proceeds to step S18, where the evaluation values are compared with other units and assigned to units with good evaluation values (steps S18, S19).

  For example, it is assumed that a new up / down call is registered when two passengers are already in a car with a full load (No. 1) and five people are scheduled to board the destination call registration floor. At this time, if there are 3 or fewer people at the landing on the upper / lower call registration floor, you may assign up / down calls to the car (Unit 1), but if there are more than 3 people, the car (Unit 1) ) Should not be assigned to the car (unit 1). At this time, since the number of people actually boarding cannot be determined with certainty, a method of determining when the boarding is the most possible is considered. In addition, even if there are 3 or fewer people at the landing, if the estimated arrival time at the upper and lower call registration floors is long, the number of people that will increase before the response can be considered. Do.

  As described above, according to the third embodiment, rather than determining the number of people to board from the past records, the actual situation is confirmed and it is determined whether the car that responds to the destination call can respond to the up and down calls. Therefore, it is possible to avoid the occurrence of unloading due to sudden demand while improving the operation efficiency.

<Fourth embodiment>
In the fourth embodiment, when up / down calls in the direction toward the destination call registration floor are assigned to all the assignable cars, the destination call is assigned by the up / down call assignment machine, and the destination call is assigned. The registered up-and-down call of a car is assigned and changed to another car. That is, when a new destination call is registered, it is only necessary to be able to assign a car to which no up / down call in the direction toward the destination call registration floor is registered, but there is one car that meets the conditions. There may be a situation where there is no stand. In that case, by changing the allocation of the upper / lower calls already assigned to the unit with good destination call allocation evaluation value to another unit, it is possible to select a car that has no registered upper / lower call allocation for destination call allocation suppression. create.

  The assigned number determination unit 42 of the elevator group management control device 3D shown in FIG. 11 is configured such that when a destination call is registered, all the cars that can be assigned a destination call are scheduled to respond to up and down calls. The function of canceling the allocation of the upper and lower calls already assigned to the car to which the destination call is assigned is configured to perform the assignment of the upper and lower calls canceled to the other car again.

  Next, based on the flowchart shown in FIG. 12, the process sequence of 4th Embodiment is demonstrated.

  In the process when the destination call shown in FIG. 12 is registered, the same step number is assigned to the same process as the flowchart of FIG. In FIG. 12, the processing of steps S41 to S44 is performed between steps S14 of step S13, and the allocation change is executed. That is, when all the units are assigned destination calls (step S41 YES), the predicted arrival times are compared between the units, and the destination call is assigned to the unit with the shortest time (steps S42, S43). Then, the up / down call of the assigned number is assigned to another number (step S44). The subsequent steps S14 to S19 are the same as those in FIG.

  As described above, according to the fourth embodiment, even when the same car responds to the destination call and the upper and lower calls, the upper and lower calls are reassigned to different units, and the same car is assigned to the destination call and the upper and lower calls. It becomes possible to avoid the situation of answering the call, and it is possible to avoid the unloading at the time of answering the destination call.

<Fifth Embodiment>
In the fifth embodiment, when a destination call and an up-and-down call in the direction toward the destination call registration floor are registered in one car, a user gets on each elevator control device 2 at the time of a destination call response. In order to avoid the situation where it cannot be completed, a command is output so as to inform the purpose of providing a restriction on the number of passengers on the up / down call response floor.

  The elevator control command output unit 38 of the elevator group management control device 3E shown in FIG. 13 outputs voice guidance to the announcement device 7 connected to each elevator control device 2 to limit the number of passengers at the time of up / down call response. To do.

  In other words, for some reason, when a destination call assignment is output to a car that has registered an up / down call in the direction toward the destination call registration floor, the up / down On the response floor, an announcement is made to limit the number of people on board. Here, an announcement is given as a means, but it may be configured so as to be known by an indicator light, a buzzer, or the like. Specifically, if the number of full passengers is 10 and the number of passengers is 2, and the destination call response time is 5 people, a configuration in which voice guidance or a buzzer is sounded when a load of 3 or more people is detected can be considered. .

  As described above, according to the fifth embodiment, it is possible to secure a space for the number of passengers when responding to a destination call even when an up / down call response is made by performing an announcement or the like for limiting the number of passengers.

<Sixth Embodiment>
In the sixth embodiment, processing related to the operation when the floor is not a destination call registration floor in an article provided with a floor that needs to be forcibly stopped when passing through a hotel lobby floor or the like will be described.

  If the 1st floor shown in Fig. 1 is a lobby floor, etc., and is a forced stop floor, if it comes up from the B1 floor, it will always stop at the 1st floor regardless of whether there is an up / down call on the 1st floor. Will do. However, if the destination call answering machine stops on the first floor, the number of people in the car at the time of the destination call response becomes uncertain, and there is a possibility that unloading occurs. Therefore, when carrying out the forced stop for the purpose of convenience as described above, the car responding to the destination call is excluded from the target cars.

  As described above, according to the sixth embodiment, for a forced stop function for the purpose of enhancing a service on a specific floor, a car that responds to a destination call is not targeted for assignment, so that a destination call This makes it possible to eliminate unloading on the response floor.

  As an exception in the above embodiments, there is a case where the assignment is not changed. For example, when there is only one stop floor while the car is moving up, and it reverses to the next floor and changes to a descent operation, it is not necessary to change the assignment. Further, if the time from the operation of the call button to the arrival of the car is within a predetermined time, for example within 1 minute, the allocation is not changed. If it is 1 minute or longer, it is possible to execute a change of allocation to prevent service degradation for the user.

  As mentioned above, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
