DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group management apparatus which manages a plurality of elevators as a group and has a landing destination button for registering a destination call at a landing.

[0002]

2. Description of the Related Art In recent years, a group management device that controls a plurality of elevators as a group can realize a large amount of information processing and advanced control by employing a microcomputer. Furthermore, when the destination call is registered by the landing destination call registration means provided at the landing, the destination call is automatically registered as a car call when the user gets on the car. Conventionally, the button operation is divided into two steps of the landing and the car. Many elevators are provided with landing destination call registration means for increasing the efficiency of elevator users who can register the desired floor by a single operation at the landing.

For this reason, there have been many proposals regarding landing destination calling means as described below. For example, Japanese Patent Laid-Open Publication No. Hei 2-163274 discloses a landing operation panel for inputting data relating to the number of destination call passengers at an elevator landing, registration means for registering the input data of the landing operation panel, and registration means registered in the registration means. Means for adding the number of passengers for each destination floor, and group management control means for at least selecting and allocating service units from the added total number of passengers for each destination floor, and setting the elevator according to the determination of the group management control means. A driving group management device has been proposed.

[0004] Similarly, JP-A-5-97333 discloses that
A means for detecting the operation of the hall call button a predetermined number of times within a predetermined time; and a hall call assigning means for giving priority to the corresponding hall call by the detection means. When a call button is operated, a group management device that controls priority assignment for a corresponding hall call has been proposed.

Japanese Patent Application Laid-Open No. 1-92181 discloses that
An elevator call button for calling an elevator is provided on each floor, the number of waiting passengers corresponding to the number of times the call button is operated is stored in advance, the number of times the call button is operated on each floor is counted, and the number of operations corresponding to the counted number of operations is corresponded. There has been proposed a method of calculating for each elevator waiting passenger on each floor based on the predicted number of waiting elevator passengers storing the number of waiting elevator passengers.

Japanese Unexamined Patent Publication (Kokai) No. 60-191976 discloses a group management device for automatically registering a landing destination call in an assigned car. When a car other than the assigned car arrives at the landing first, the service status of the landing is changed. A group management device has been proposed which automatically determines a hall call to the first car when this service state becomes worse than a certain value and prevents registration of a car call corresponding to the destination call to the assigned car.

[0007] Japanese Patent Publication No. 27945/1990 refers to a hall call response availability table and a destination floor availability table based on destination floor information from an arbitrary landing for uneven floors having irregular service floors. There has been proposed a method of selecting a service machine from those capable of responding to a hall call and capable of providing a destination floor service.

[0008]

SUMMARY OF THE INVENTION As described above,
In the conventional elevator group management device disclosed in JP-A-163274, an elevator user has to input data relating to a desired destination floor and the number of passengers by using a landing operation panel installed on each floor. It is troublesome.

In the example disclosed in Japanese Patent Application Laid-Open No. 5-97333, it is necessary to have an elevator user operate the hall call button a predetermined number of times at a predetermined time, which is very troublesome. , The number of waiting passengers is predicted, but the number of operations within a predetermined time alone cannot be used to accurately predict the number of passengers, and optimal elevator group management cannot be achieved.

Further, in the example disclosed in Japanese Patent Application Laid-Open No. 1-92181, it is necessary to prepare a table corresponding to the operation count, which consumes extra memory.

In the example disclosed in Japanese Patent Application Laid-Open No. 60-191976, the first car or the assigned car is used to determine whether or not to register a landing destination call to the first car based on the service status at the passenger's hall. It does not detect how many waiting passengers at the landing have boarded or not, and automatically registers the destination call at the landing in either one in anticipation that it will get into the first-arrival car or assigned car only with the service state, Automatic registration of a landing destination call to the optimal car cannot be performed.

In the example disclosed in Japanese Patent Publication No. 1-27945, a service machine is selected from those capable of responding to a hall call and capable of providing a destination floor service with reference to a hall call responsive table and a destination floor availability table. As a result, it is necessary to prepare a hall call response table and a destination floor availability table, which consumes extra memory.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. A first object of the present invention is to provide an elevator group management device provided with a landing destination button without requiring extra operation. An object of the present invention is to provide an elevator group management device that performs optimum group management with a minimum number of operations. A second object is to provide an elevator group management device capable of accurately grasping the number of waiting passengers. A third object is to change the assignment status of the assigned car by accurately grasping the number of passengers, thereby shortening the waiting time of the passengers at the landing or the car. Also, the fourth
It is an object of the present invention to improve the serviceability for waiting passengers at the landing by appropriately changing the automatic registration of the destination floor registered at the landing in accordance with the usage status of the passengers. A fifth object of the present invention is to provide an elevator group management apparatus that transports a waiting passenger to a desired destination floor at an optimum time by using a simple configuration that does not require an extra memory.

【Example】

Embodiment 1 FIG. FIG. 1 is a configuration diagram showing the configuration of the present embodiment. In the figure, 1 is a group management device that manages the operation of a plurality of cars as a group, 2 is provided for each car, and each car is provided. A car control means 3 for controlling the operation of the car, a landing destination call registration means 4 for registering a destination call which may be installed on a specific floor such as an entrance floor or a plurality of floors at a landing, 4 A hall lantern is provided near a car entrance (not shown) and predicts that a corresponding car has been assigned to a hall call by, for example, light emission, voice, or the like.

FIG. 2 is a block diagram showing a detailed configuration of the group management device 1. In the figure, reference numeral 11 designates an assigned car to respond to a landing destination call based on a predetermined evaluation method. Assigned car selection means to respond, 12
Is a car communication means for performing communication between the group management device 1 and the car control means 2, and 13 is an assigned car (hereinafter referred to as a forecast car) assigned by the assigned car selection means 11 at the landing and gets on the forecast car. Is detected, a car call automatic registration means for automatically registering the destination call registered at the hall as a car call, and a waiting call to the forecast car by counting the number of destination calls registered on the hall destination call registration button 3 This is a destination call counting means for detecting the number of passengers.

15 is a boarding destination call counting means for counting and storing the number of automatically registered floors of the destination floor registered as a car call by the car call automatic registration means 13, and 16 is a car stopping at the registered floor. A boarding load detection device that detects and stores a car load when a passenger gets on the car when performing a service, and 17 sets a destination floor from the boarding destination call counting means 15 and the boarding load detection device 16. This is a unit passenger detection device for estimating the expected number of passengers per landing destination call registration button (not shown).

Reference numeral 18 denotes a forecast missed car detecting means for detecting that a car other than the forecasted car (hereinafter referred to as a forecast missed car) arrives at the landing where the destination call is registered, and 19 denotes a forecast missed by the forecast missed car detecting means 18. When the car is detected, the load of the passenger on the out-of-forecast car is detected and stored, and the load of the passenger on the forecast car is further detected and stored. A boarding load detecting means 20 for registering, based on the result of the boarding load detecting means 19, performs destination call registration to the out-of-forecast car, and prevents car call automatic registration preventing means for preventing destination call registration in the forecasted car. It is.

Reference numeral 21 denotes a stepped call discriminating means for discriminating that a destination call on a stepped floor with irregular services in the upper or lower direction has been pressed by the landing destination call registration button 3.

In the present embodiment, as a function of the assigned car selecting means 11 in the group management device 1, the number of waiting passengers at the hall where the destination call is registered is predicted based on the output of the destination call counting means 14, When it is determined that the forecasted car alone cannot provide service to all the waiting passengers, the case where the car assignment status is changed is shown in FIG. 3 using a flowchart showing a procedure for changing the car assignment status as necessary. The case where the forecast car is an additional allocating means for additionally allocating another car will be described.

In step ST21, when it is detected that the elevator user at the hall has registered the hall destination call with the hall destination call registration button 3, it is necessary to perform a predetermined evaluation for determining a car which responds to the hall call. , Step ST
At 22, a counter i representing the number of cars of a plurality of cars (three in this embodiment) is initialized, and a predetermined evaluation is performed for car 0 first. Similarly, in step ST23, the counter fl representing the floor at which the car is stopped and the evaluation value V (i) for the car i are initialized.

By repeating steps ST24 to ST28, the predicted waiting time W (fl) is calculated for all the stopped floors of the car No. 0, and the predicted waiting times W (fl) are added to add the predicted waiting time W (fl). Evaluation value V (0)
Is calculated. The evaluation value V (0) of the car No. 0 calculated in this way is stored in a memory (not shown) or the like, and is used for future evaluation of the car.

The estimated waiting time W (fl) is, for example, for a waiting passenger who has registered an UP on the fifth floor,
Call duration (from the time the car call was registered on the 5th floor to the present) and estimated arrival time (from the floor where Unit 0 currently exists to the 5th floor while servicing the hall call and car call on other floors) Estimated arrival time). If the hall call and the car call are not registered such that the car No. 0 stops at the fourth floor, for example, at step ST24, the estimated waiting time W of the passenger on the fourth floor
(4) is zero because it does not exist.

By repeating steps ST23 to ST34, an evaluation value V (i) for a newly registered hall call is calculated for all cars. In step ST35, the evaluation value V calculated as described above
By comparing (i), the car having the smallest evaluation value V (i), for example, the first car, was selected as the assigned car, and the hall call was registered in the car control means 2 corresponding to the first car. By registering to respond to the floor, the vehicle is dispatched as a forecast car to the hall call registration floor. Along with this dispatch, the hall lantern 4 corresponding to the first car installed near the car entrance is lit on the floor where a new hall call is registered, and a car 1 is provided as a forecast car to the passengers of the hall with sound and the like. Forecast that the unit has been registered.

In step ST36, in step ST21
The number of destination call registered floors registered with the destination call is counted by the landing destination call registration button 3 of the elevator user of the hall detected by the above, and the number of registered floors of the destination call registered at this hall is determined. Determine if the value is exceeded. If the registered floor number of the destination call is within a predetermined value, it is determined that there are few people waiting for the car at the landing, and the service is provided by the forecast car, which is the first car assigned by step ST35. . However, if the number of registered floors of the destination floor exceeds a predetermined value, the destination call registration button 3
In response to the destination call registration, it can be determined that there are a large number of passengers waiting for a car at the landing, so in anticipation that there are people who cannot be covered by the assigned forecast car, a different forecast car is set in step ST37. An additional assigned car (hereinafter referred to as an additional car) is additionally assigned.

When deciding which car to perform this additional allocation,
By additionally allocating the car i which corresponds to the evaluation value V (i) next to the evaluation value V (1) of the first car assigned in step ST35, the service time for the waiting passenger is reduced.

Here, if the additional car i to which the additional assignment has been made is not forecasted by the hall lantern 4 or if no one can get on the forecasted car No. 1, the passengers at the hall will enter the hall destination call registration button. Be sure to re-register 3. If the hall destination call is not re-registered, the configuration of canceling the assignment of the additional car i-th car is made. With such a configuration, it is possible to prevent the car from being dispatched to a hall where no hall call is generated. Further, in the present embodiment, the description has been made of the additional allocation. However, the present invention is not limited to this, and a similar effect can be obtained by making a forecast of a plurality of vehicles at the landing as an additional forecast.

In the present embodiment, a method for obtaining a predetermined value for determining whether or not to allocate an additional car based on the number of registered destination floors is described. However, a predetermined value may be used, or the load on the car may be reduced. The number of people who can get on the car further is determined by a device to detect (weight sensor or surveillance camera with video etc.) etc., and the relationship between the number of people who can get on the car and the expected number of waiting passengers who will stop even from the number of registered floors at the destination floor It goes without saying that a similar effect can be obtained even if it is determined whether or not to perform additional allocation of cars.

Embodiment 2 FIG. In the present embodiment, a penalty value is provided in the process of calculating the evaluation value V (i) of the car i as a function of the assigned car selecting means 11 in the group management device 1 so that it is difficult to be assigned to a hall call on another floor. The case of the allocation limiting means will be described with reference to the flowchart of FIG. Here, for convenience of explanation, a description will be given based on FIG. 1 assuming that there are a total of three cars from the 0th to the 2nd and that the car operation service floor is a total of 5 floors from the 1st floor to the 5th floor.

Steps ST21 to ST28 are the same as those in the first embodiment, and a description thereof will be omitted. Step S
When the evaluation value V (i) based on the predicted waiting time W (i) of the car i for all floors is obtained by T27, the car for the evaluation value V (i) of the car i is obtained. When the i-th car is registered with the last landing destination call, it is determined in step ST29 whether or not a penalty value Wp (i) is set (described later). If the penalty value is set, the penalty value is determined in step ST30. Wp
A value obtained by adding (i) to the evaluation value V (i) is used as a new evaluation value V
(I) is stored in a memory (not shown) or the like.
If penalty value Wp (i) has not been set for car i, the evaluation value V (i) calculated up to step ST27 is stored in a memory or the like as it is, and the process proceeds to step ST33.

After step ST33, evaluation values V (0), V (1), V (2) for all cars are the same as in the first embodiment.
Is obtained, and a hall call is registered in the car i, for example, the car 1 in which the evaluation value V (i) is minimized in step ST35. For example, assuming that the first car is assigned in step ST36 in correspondence with a new hall destination call, the number of destination floors registered in the hall destination call registration button 3 for the first car is counted, and registered at this hall. As a result of determining whether or not the number of registered floors of the designated destination floor exceeds a predetermined value, when it is determined that the number exceeds the predetermined value, the number of passengers in the new landing destination call registration floor that is equal to or higher than the predetermined value is determined. It can be determined that the first car comes in, and the first car stops at least on the floor above a predetermined value and performs the service. Since the waiting time of the passengers in the car increases with the service to many floors, the process proceeds to step ST38, and the penalty value Wp (1) is given to the first car, which is the forecast car.
Is set so that this first car is unlikely to be registered in a new landing destination call that will be registered in the next other floor.

The added penalty value Wp (1)
Is set for the first car and therefore exists without being initialized in the calculation of the evaluation value V (1) for the next landing destination call registration, and the evaluation value of the first car Affects the calculation of V (1). Further, in this embodiment, the penalty value Wp (i) for the car i is described as being valid only for the next landing destination call registration, but the penalty value Wp for the car i is described.
(I) may correspond to a plurality of hall destination calls and may be continued evenly. Further, when corresponding to a plurality of hall calls, service is provided to the hall call registered in the car i. Needless to say, a more optimal group management system can be obtained by gradually lowering the penalty value Wp (i) every time the landing destination call is registered.

The penalty value Wp set here is
The value of (i) may be a value specified in advance with reference to an elevator service floor or the like, or a variable value that changes in accordance with the number of floors registered in the destination call registration button 3. May be. Furthermore, by increasing the penalty value in the present embodiment, it is difficult to assign a call to a hall call on another floor.

Embodiment 3 FIG. FIG. 5 is a flow chart for the group management device 1 in the present embodiment to determine the assigned car based on a predetermined evaluation method, and then to know the current state of the elevator user in order to improve the efficiency of car dispatch in the future. is there.
When the forecasted car assigned in step ST42 arrives at the hall where the hall destination call is registered in step ST41, the elevator user who has registered the hall destination call gets into the car. When the elevator user gets into the assigned car, the elevator user gets into the car using, for example, a weight sensor + surveillance camera, which is the on-board load detection means 16 (not shown) attached to the car. Step ST4: Number of elevator users
3 and store it in a memory (not shown) in the group management device 1.

When the destination floor registered by the landing destination call registration button 3 is registered in the assigned car by the automatic car call registration means 13, the destination registered floor set in step ST44 is detected and the group management is performed. It is stored in a memory (not shown) in the device 1. In step ST45, based on the values detected and stored in steps ST43 and ST44, the set destination floor, that is, the destination button 1
The number of passengers per vehicle is determined, and the number of passengers per destination button determined in this way is stored in a memory (not shown) in the group management device 4 and is used for the timing of car dispatch. .

This method is used for dispatching a car. For example, one example is that the current car M has five passengers, and the maximum number of passengers is eight per car. I will explain as far as it goes. It is assumed that five passengers in the car M have registered car calls on the fourth floor of the second floor, the third floor, the sixth floor, and the eighth floor in registration of the landing destination call.
Here, the landing destination call on the second floor is the fourth floor, the fifth floor, and the sixth floor.
If the fourth floor of the eighth floor and the eighth floor are registered, and based on a predetermined evaluation method, if the car M with five passengers is assigned to the landing destination call on the second floor, the calculation of the flow chart Can be calculated to be approximately one person per destination button. Therefore, at least about one passenger gets off the second floor in this car M, and the destination call registration floor on the second floor is registered on the fourth floor.
Since it can be determined that a car is waiting on the floor, when the car No. M services the second floor, one person gets off and at least four people get on, so the number of passengers of the car No. M is at least seven. In such a state of the car, the car stops responding to the subsequent landing destination call, and reacts to the landing destination call after the number of passengers in the car M decreases. In this way, the number of people descending on the floor, the number of people in the car, and the like are detected to control the dispatch timing of the car.

Embodiment 4 FIG. FIG. 6 is a flowchart of the automatic car call registration when the assigned car selection means 11 in this embodiment determines a car to be assigned based on a predetermined evaluation method and a car out of the forecast occurs due to the dispatch. In step ST52, the group management device 1 is
When it is detected that a car out of the forecast is different from the forecast car assigned in step ST53, it is determined in step ST53.
In the forecast, the surveillance camera provided at the hall, which is the boarding load detection means 19, monitors the number of passengers in the car, and the number of waiting passengers on the car. Is detected by a weight sensor for detecting a change in the weight of the car. Next, in step ST54, when the forecast car arrives later, the boarding load detecting means 19 similarly detects the boarding status (boarding load Fy) of the waiting passenger at the hall where the car is to be boarded.

In step ST55, the boarding load Fs on the car out of the forecast is compared with the boarding load Fy on the forecasted car. If Fs> Fy, the waiting passengers at the landing judge that most people have boarded the forecasted missed car that arrived earlier, register the landing destination call registration in the forecasted missed car, and in step ST56 the forecasted arrival that arrives later. The registration of the landing destination call to the car is blocked by the car call automatic registration blocking means 20. If Fs <Fy, it is determined that the waiting passengers at the landing did not get on the unexpected car that arrived earlier,
In step ST57, the landing destination call is not registered in the car outside the forecast, but the landing destination registration is automatically registered in the forecast car arriving later.

Embodiment 5 FIG. FIG. 7 is a configuration diagram showing the configuration of the present embodiment. The same numbers as those in FIG. 1 described in the first embodiment have the same configurations, and as shown in FIG.
Group management is performed by a total of four elevators of Unit No. 0
Units 1 and 1 provide services on the 6th floor from the 1st floor to 6th floor, and Units 2 and 3 provide services on the 1st and 6th floors from the 1st floor to the 6th floor.
Although the description will be made based on the configuration for providing service to the floors, it goes without saying that the present invention can be applied regardless of the number of cars installed and the number of floors.

FIG. 8 shows a function of the assigned car selecting means 11 in the group management device 1 in this embodiment, in which the bonus value of the stepped car is increased based on the output of the stepped call discriminating means 21 so that the car can be easily assigned to the hall call. It is a flowchart showing the case where the allocation status of a car is changed. Steps ST21 to ST28 are the same as those in the first embodiment, and a description thereof will be omitted. When the evaluation value V (i) based on the predicted waiting time W (i) of the car i for all floors is obtained by step ST27, the destination call registered by the hall destination call registration button 3 is stepped in step ST31. Floor destination call (in this embodiment, B1
It is determined whether or not the destination call is not registered on a stepped floor (step ST27).
The evaluation value V (i) calculated as described above is stored in a memory or the like as it is, and the process proceeds to the next step. If the destination call is to be registered for a stepped floor, the process proceeds to step ST32, and if the car i is a car serving the stepped floor (in the present embodiment, the car of the second and third cars is shown), A preset bonus value Wb (i) is drawn from a memory or the like, the value is subtracted from the evaluation value V (i), and the subtracted value is replaced with the evaluation value V (i) and stored in the memory. Proceed to the next step. Here, if the i-th car is not a car that serves the uneven floor (in this embodiment, it indicates the 0-th car and the first car), the bonus value Wb (i) is set to 0 in advance.
No change occurs in the evaluation value V (i) of the car which does not service the uneven floor if the value of is set. Step S
After T33, evaluation values V (0), V (1), V (2), and V (3) for all cars are obtained in the same manner as in the first embodiment.
The hall call is registered in the car having the smallest evaluation value V (i).

Although the bonus value Wb (i) has been described as a preset value in the present embodiment, it may be a variable value set in accordance with the stepped floor service state by the landing destination registration button 3, and may be a variable value. A configuration in which the evaluation value V (i) of the car (in the present embodiment, the second car and the third car) that services the uneven floor is reduced in accordance with the service situation, and the service for the destination call registration on the uneven floor is given any priority. Then, the present invention holds.

[0055]

Since the present invention is configured as described above, it has the following effects.

Even after a car that responds to the hall call is determined in response to the destination call at the hall, the load on the car is detected without requiring extra operation, and the dispatch of the car is changed. The car can be dispatched according to the situation.

Based on the output of the destination call registration means at the landing, the number of waiting passengers at the landing can be estimated without requiring any extra operation. Further, since the dispatch of the car is changed according to the number of waiting passengers, the dispatch of the car can be performed in a fine manner according to the situation of the landing.

Based on the output of the destination call registration means at the landing, the number of waiting passengers at the landing can be estimated without requiring any extra operation. Further, since the dispatch of the car is changed according to the number of waiting passengers, the dispatch of the car can be performed in a fine manner according to the condition of the landing.

When the number of waiting passengers at the landing is estimated based on the output of the destination call registration means at the landing without requiring any extra operation, and it is determined that the number of waiting passengers exceeds a predetermined value, An additional car will be dispatched to the platform separately from the predicted assigned car, so the waiting time for passengers left behind at the platform will be further shortened according to the number of passengers waiting at the platform, and the car will be dispatched. Serviceability is improved.

When the number of waiting passengers at the landing is estimated based on the output of the destination call registration means at the landing without requiring any extra operation, and it is determined that the number of waiting passengers exceeds a predetermined value, A penalty value will be set for the car that responded to the landing, and the car will be decided on the corresponding car in consideration of the penalty value for future landing destination calls on other floors, so it is decided that some passengers will get on the car , The car service can be performed without making the riding time in the car longer than necessary, which is the time for responding to the car call of many passengers in the car.

From the output of the landing destination call registering means and the output value of the passenger load detecting means for detecting the load of the passenger at the landing, the state of the passengers entering the landing without requiring any extra operation, ie, the destination floor , The total number of people in the current car, etc. can be detected. Further, by controlling the car based on such information, it is possible to perform fine control according to the passenger.

When the number of passengers in the forecasted car is smaller than the number of passengers in the out-of-forecast car, a destination call is registered for the out-of-forecast car, and the passenger in the out-of-forecast car is again called for a car. This eliminates the need for re-registration, and does not register wasteful destination calls from waiting passengers at the landing for forecasted cars with a small number of passengers, so the forecasted car will not stop on floors that do not require passengers in the future. The waiting time in the car for passengers in the car can be reduced.

When a bumped call is detected, a bonus value is set for a car that can handle the bumped call, so that an extra memory or the like in which a car capable of serving the bumped floor is registered is not required, and the same as in the past. The optimum car can be selected by the predetermined evaluation, and further, by setting the bonus value, the car can be dispatched without assigning the uneven car to the uneven call.
