DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation control device for an elevator, and more particularly to an operation control device for changing the operation of a car according to the use condition.

[0002]

2. Description of the Related Art Operation control in a so-called group management elevator in which a plurality of elevators service a multi-storey floor is to select and determine an elevator that responds to a generated hall call. Thereafter, an evaluation value such as a waiting time until a hall call generated for each elevator is serviced is calculated, and a hall call allocation method is used in which an elevator to be serviced is determined based on the evaluation value.

[0003] As seen in Japanese Patent Application Laid-Open No. 59-177267, elevators with a larger capacity are assigned to congested floors, and in Japanese Patent Application Laid-Open No. 55-140468,
Some landing calls on specific floors have a priority set so that a specific elevator is preferentially assigned. Further, when a wheelchair button is provided, an operation control is performed such that a wheelchair dedicated elevator is assigned when there is a wheelchair button call, and an elevator to which a VIP call is assigned is separated from the group of group management and operated exclusively. Has been done.

On the other hand, Japanese Patent Application Laid-Open No. 2-127376 discloses a "vacant elevator" in order to respond to various demands of users.
And the technology to select "early arrival elevator" at the landing.

[0005]

SUMMARY OF THE INVENTION The above-mentioned Japanese Patent Application Laid-Open No. 55-1404
No. 68, Japanese Unexamined Patent Publication No. 59-177267, and responses to wheelchair calls, etc., provide a specific elevator service for a specific hall call, and do not respond to various requests of general users. Also, the response to the VIP call is to service the elevator separated from the group control operation control for a specific hall call, and does not respond to various requests. Also, in Japanese Patent Application Laid-Open No. 2-127376, even if an elevator in a state designated by a passenger is selected and assigned at a landing, the state change after the service of the hall call is not considered at all, and the call is generated. There is no guarantee that the user will be in his desired condition up to the destination floor.

[0006] In addition, while a strong person prefers a direct elevator, such as when going from the first floor to a rooftop in a high-rise building, a weak person may be uncomfortable due to a sudden change in altitude due to a sudden change in altitude. Because of this, it may be preferable to slow down slowly, or stop several times in the middle of the floor to allow time to adapt to changes in air pressure. There is also a demand that a specific service or specific guidance be provided only to a user from a specific floor or a user at a specific hall call.
If the elevator is operated exclusively to satisfy such various requirements, the entire elevator group cannot be operated efficiently, and the problem that the waiting time is extremely deteriorated and the transportation capacity is insufficient is disadvantageously caused. Occurs.

An object of the present invention is to achieve efficient operation control by assigning an attribute to each elevator and assigning calls based on the attribute in order to solve the above problems.

[0008]

In order to solve the above problems, based on information from a hall call collecting means and an attribute table in which a plurality of attributes are recorded in advance in a group management control device,
Based on the type of hall call and the floor of the floor, it is determined whether or not the attribute should be registered, and if so, what kind of attribute the elevator should have, and a car with the same attribute already exists in the car attribute table. An attribute registration unit that determines whether or not a car is registered, and a car attribute table that registers a car attribute based on information in the attribute registration unit are provided, and call assignment is performed in consideration of the information in the car attribute table. This can be solved by performing control.

[0009]

With the above configuration, an efficient operation control can be realized by giving an elevator an attribute that is valid for a certain period and performing assignment control using the attribute.

That is, if a vacant elevator is selected and responds to the hall call, the service elevator is given the attribute of a vacant elevator until the user arrives at the destination floor and the service is finished, and the elevator is given If the number of passengers is controlled to limit the call assignment so that it does not exceed a certain value, or if the weak person uses it in a high-rise building, reduce the speed as an elevator for the weak or stop on the way until reaching the destination floor, for example, the end floor The operation control is performed so as to stop at the floor, and after the service of all the users using the elevator is completed, for example, after the end floor service, the attribute is released and the normal assignment is performed.

In addition, the elevator having the attribute responds to the normal assignment to the extent that the attribute is not impaired, so that the efficiency of the entire elevator group can be ensured according to the request of the user. It is.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall configuration diagram of an elevator operation control device according to the present invention.

Signals of the hall call buttons 101 to 10n are sent to the hall call collection unit 31 in the group control unit 3 through the transmission line 2. In this figure, the hall call button is a normal up / down call button, but a call button for selectively calling an elevator according to the user's preference may be provided. The signals of the car call buttons 41 to 44 are
The car control devices 61-6 through the car transmission lines 51-54 as car information together with the weight etc. in the elevator.
4 The car information transmitted to the car control devices 61 to 64 is sent to the car information collection unit 32 in the group management control device 3 via the control device transmission line 7 together with the information possessed by the car control devices. The attribute registration unit 33 refers to the information of the hall call collection unit 31 and the car call information collection unit 32 and adds a predetermined attribute to a part of the elevator for a predetermined period with reference to the attribute content table to the car attribute table 35. Record.
It should be noted that the attribute registration unit 33 naturally searches for an elevator in which the same attribute is already recorded in the car attribute table. The assignment control unit 36 determines the elevator to service the generated hall call based on the attributes of the car attribute table 35 and the information collected by the hall call collection unit 31, and transmits the result through the control device transmission line 7 to the car control system. Send to devices 61-64. Unit control device 61
64 drive the motors 81 to 84 based on the allocation result and drive control the hoisting machines 91 to 94, thereby moving the elevators 111 to 114 to service hall calls. In addition, one end of a driving rope of each elevator is provided with counterweights 121 to 124.
Is provided. In this figure, display devices 131 to 13n are provided in each hall, and it is also possible to notify the display device of the attribute of a car arriving.

In this way, by providing the attributes of each elevator in the car attribute table until the completion of the service, the operation of the elevator can be controlled in a state desired by the user, and a decrease in the operating efficiency of the entire system is minimized. There is an effect that it can be limited.

FIG. 2 is a flowchart showing the outline of the operation of the present invention.

First, when it is detected (201) that a hall call button or a specific car call button on a floor which has been registered in advance is pressed (201), the attribute registration unit 33 reads the corresponding attribute from the attribute content table 34. Search (202). Next, in the case of the hall call button, the attribute is written in the elevator portion of the car attribute table 35 to which the hall call is assigned, and in the case of the car call, the attribute is written in the elevator portion where the car call occurred (203). ). Next, when a hall call occurs, the assignment control unit 36
In determining an elevator to service a hall call, the car attribute table 35 is checked (204), and if the car attribute table 35 has a description, even if the generated hall call is assigned to an elevator having the same attribute, It is determined whether or not the attribute is satisfied (205). If the attribute is no longer satisfied when assigned to an elevator that already has the same attribute, the elevator is excluded from the assignment target and a service elevator is determined (206). Otherwise, the service elevator is removed from all elevators. It is determined (207). At the time of this assignment, it is possible to make it easier to assign elevators having the same attribute by assigning weights to elevators having attributes so that evaluation values are easily selected. When the user to which the attribute is added is disembarked (208) when the elevator having the attribute arrives at the end floor or the like, the car attribute table 35 is cleared and the attribute is released (209).

FIG. 3 is an explanatory diagram of the operation of each elevator according to the present invention.

In FIG. 3, it is assumed that an instruction is given for giving priority to the boarding time on the seventh and eighth floors. FIG.
When a hall call occurs on the seventh floor as in (a), an elevator to service the hall call is determined, and an attribute called "riding time priority service" is added to the car attribute table 35 of the determined elevator. You. Here, assuming that the elevator having the minimum waiting time is assigned, the car A becomes the service elevator. The attribute of "riding time priority service" is, for example, a condition that the arrival time of a car call to arrive at the destination floor after arriving at the allocated hall call is equal to or less than a predetermined value.
The floor and attribute conditions are set to an arrival time of 20 seconds or less.

In FIG. 3 (b), when determining the service elevator for the next generated hall call on the fifth floor, the car attribute table 35 is first examined to determine the condition of the attribute "riding time priority service" of the car A. It is checked whether the arrival time from the seventh floor to the third floor is 20 seconds. In this case, even if the vehicle is stopped at the fifth floor for 10 seconds, this condition is satisfied, and the elevator having the shortest time to arrive at the fifth floor is selected from all the elevators. In the case of FIG. 3B, the car A is selected.

Next, it is assumed that a hall call occurs on the fourth floor as shown in FIG. In this case as well, the A car arrives first, but if a hall call is assigned to the A car, the elevator will not satisfy the elevator of 20 seconds or less which is the condition of the attribute "riding time priority service" of the A car. The service elevator is selected and assigned from the remaining units. In the case of FIG. 3 (c), the elevator of B is determined as the service elevator.

As shown in FIG. 3 (d), when the car A arrives at the third floor and the user from the seventh floor, from which the attribute is added, gets off, the car attribute table 35 is cleared, and the ordinary car attribute table is cleared. The call assignment is performed.

The above example assumes that the user from the seventh floor has pressed the car call button on the third floor immediately after boarding, and determines and controls the destination of the user.
If the car call button is not pressed even though the user has boarded, make sure that the attributes are maintained up to the farthest floor or the end floor of the registered car call, and then the car attribute table is cleared. To Further, a destination floor button may be provided at the landing.

As described above, the attributes to be added to each elevator include a direct operation, a single company operation in a tenant building, and the like. According to the present embodiment, various different operations can be performed without providing a dedicated elevator.

FIG. 4 shows an example in which calls after the attribute release are normally assigned.

The difference between FIG. 1 and FIG.
It is in the point provided. The situation estimation device 37 includes a hall call collection unit 31, a car information collection unit 32, and an assignment control unit 36.
Of the elevator at the future position is estimated based on the information and the assignment result. When a hall call occurs, the situation estimating unit 37 estimates that the elevator arrives at the hall call occurrence floor, assuming that the elevator having the attribute for the hall call is serving, and the attribute of the elevator indicates that the elevator has the attribute. If it has been released by the time, the assignment control unit 36 determines the service elevator including the elevator.

FIG. 5 is a flowchart showing an embodiment of the above-mentioned apparatus in which calls after the attribute release floor are normally assigned.

A call is assigned to an elevator having an attribute to determine whether the attribute condition is satisfied (205). If the attribute condition is not satisfied, the situation estimating unit 37 estimates the situation at the time of arrival at the calling hall floor. (501). Based on the estimation result, it is determined whether or not the attribute has been released when the vehicle arrives at the calling hall floor, and whether or not the attribute exists (5).
02) If there is no attribute, an assigned elevator is selected from all elevators and assigned (207). If the attribute is still added, the assignment is performed excluding the car having the attribute (206).

FIG. 6 shows an embodiment in which different control is performed for each floor.

5 differs from FIG. 5 in that an attribute registration device 14 is provided and a floor-specific attribute table 38 is provided in the attribute content table 34. Attribute content table 3
4, an attribute for each floor is registered, and when a hall call occurs, the attribute registration unit 33 assigns the attribute added to the hall call occurrence floor in the attribute content table 34 to the elevator assigned to the hall call. It is registered in the car attribute table 36. The attribute for each floor may be registered in the attribute content table in advance, or may be registered and changed by the attribute registration device 14. Also, this attribute registration device 14
In addition to the attribute registration for each floor, other attributes may be registered and changed.

FIG. 7 is an explanatory diagram of the operation when different control is performed for each floor. This drawing relates to a service for a passenger who is riding in an elevator, and an example of the contents will be described below.

FIG. 7A shows a specific guidance display for a user from a specific floor. Assuming that the specific display service floor is the third floor, a display dedicated to the user on that floor is displayed on the A-unit that has served that floor as shown in the figure. If you do this,
It is possible to perform display according to the user for each floor.

FIG. 7 (b) shows a case where a plurality of companies are occupying a tenant building or the like, in order to prevent employees of different companies from riding together, a hall call on a floor containing different companies is required. May not want to assign the same elevator. In this example,
The eighth, seventh and fourth floors are the floors occupied by the person A. In this case A
At the time when the car stops at the 7th floor in response to the hall call on the 7th floor, the car A becomes the elevator for the company A and the car A is not assigned to the hall call on the 5th floor occupied by the party B. ,
In the case of this figure, it is assigned to the B-unit. This way, you wo n’t be sharing with other users,
Each company person can use the elevator as if it were a private elevator.

FIG. 7C shows an example in which the above-mentioned boarding time is preferentially controlled and an elevator arriving at the destination floor within a predetermined time is allocated. The 8th and 7th floors are boarding time priority service floors, and a user who generates a hall call on this floor is controlled so that the user can go to the destination floor in 20 seconds or less. In the case of the figure, the destination floor is the third floor, and in the state of the figure, the seventh floor and the fifth floor
It is assumed that the hall call on the floor is assigned to Unit A. When a call to the 7th floor hall was assigned to Unit A, 3
Assuming that the arrival time to the floor is 16 seconds and the next hall call on the 4th floor is to be assigned to Unit A, the arrival time on the 3rd floor is 2 seconds, assuming that the stoppage on the 1st floor takes 10 seconds.
Since it is 6 seconds, which exceeds the standard 20 seconds, 4
Floor hall calls are assigned to elevators other than the A-unit. With such control, the arrival time can be kept within a certain time.

FIG. 7D shows an example in which the degree of congestion in the car is controlled to a predetermined value or less. It is assumed that the eighth and seventh floors are set as the congestion degree priority service floors in the car.
Now, car A is assigned to the hall call generated on the 7th floor, and the number of people in the elevator exceeds the limit at the time the 7th floor is serviced. Can be In the case of this figure, the hall call generated on the fifth floor is assigned to the car B.

FIG. 8 shows an example of the attribute table. Attributes for each car (elevator), service start floor for attributes,
The end floor and its conditions are described.

FIG. 9 shows an example of the attribute content table. For each specific event, for example, the occurrence of a hall call on a specific floor, the registration of a special call, the weight sensor, the sensor in the car, and the like, the attribute to be added to the elevator, the attribute condition, and the release condition are described. Further, an execution condition may be added such that the control is performed only at a specific time or the main control is not performed during a congested time period.

FIG. 10 shows an example in which the transfer is smoothly performed by the shuttle elevator and the local elevator. In order to make the transfer between the shuttle elevator and the local elevator smooth, a method has been proposed in which one waits until one arrives, but this method reduces the efficiency of the waiter. . Therefore, when the arrival time of the shuttle elevator at the connecting floor is determined, an attribute specifying the range of the arrival time is given to the local elevator, and a call is assigned to the local elevator arriving within the specified arrival time range. , The control according to the attribute is performed so as not to exceed the range. In this figure, when the local elevator C is designated as the transfer elevator of the shuttle elevator A, the range of the arrival time of the car C is designated, and control is performed so as to fall within this range. According to the present embodiment, there is an effect that the transit can be performed smoothly while suppressing the decrease in the efficiency of the local elevator.

FIG. 11 shows an example in which a button for the weak is used. The role of the elevator equipment is to quickly transport passengers to the destination floor, and it is generally desired to arrive at the destination floor without stopping. On the other hand, if you go straight to the destination floor in a high-rise building, you may have discomfort due to the pressure change due to a sudden rise, and it may be better for the weak to arrive at the destination floor while stopping in some places. In such a case, prepare a button for the weak at the landing or in the car, and when this button is pressed, slow down the speed and climb up, stop as much as possible to call the hall on the middle floor, The user can adapt to changes in air pressure by making the deceleration pattern stepwise or the like.

FIG. 11A shows an example in which a weak button is provided as a "slow button" in addition to a normal hall call button. FIG. 11B shows an example in which the button for the weak is graphically displayed. FIG. 11C shows an elevator operation diagram in a normal case, in which the horizontal axis represents time and the vertical axis represents the number of floors. FIG. 11D shows a case where the weak button is pressed.
This is an example of a deceleration operation. In normal operation, 8
When the vehicle arrives at the 0th floor, if the weak button is pressed, the vehicle will decelerate and take about 80 seconds to arrive at the 80th floor. FIG.
(E) is an example of halfway stop floor control. In this example, the vehicle was stopped four times on the way floor and arrived at the 80th floor in 85 seconds. In the above description, the change in atmospheric pressure has been described. However, since some sick people are concerned about the change in acceleration / deceleration, an attribute of lowering the acceleration / deceleration may be given. According to the present embodiment, it is possible to reduce the discomfort due to a change in atmospheric pressure or acceleration of a weak person while ensuring the convenience of a healthy person.

FIG. 12 shows an example of the observation operation of the observation elevator. Observation elevators are also equipped with observation buttons for ordinary users and those who want to enjoy the view, and when the observation button is pressed, slow down the elevator and drive to enjoy the view. FIG. 12A shows an example in which a hall call button for observation driving and a hall call button for normal driving are provided side by side. FIG. 12B is an example in which the view button is designed. FIG. 12C is an operation diagram illustrating a difference between the observation elevator and the normal operation. As shown in the figure, in response to the call for the observatory elevator, the vehicle is driven so that the deceleration control is performed so that the view can be enjoyed slowly. FIG.
FIG. 2 (d) shows an example in which a part of a tenant is used as an office building (up to the sixth floor is an office building) and an observation elevator (sixth floor or more) is provided. In this case, even if the call button for observation is pressed, normal operation is performed until the car call on the office floor ends the service, and control is performed so that observation operation is performed after passing the office floor. The vehicle can be operated in a prospective manner without impairing the convenience of floor users. In this case, as the car attributes, two types of attributes are added, that is, an observation operation and a normal operation up to the sixth floor. FIG. 12 (e) shows the operation diagram of FIG. 12 (c). As shown in the figure, in response to the observation hall call, drive normally to the destination floor up to the 6th floor in normal operation, and after the 6th floor, reduce the speed and perform the observation operation, enjoy the view over time Is what you can do. According to this embodiment, we want to arrive as soon as possible.
It can satisfy both office users and those who want to enjoy the view. FIG. 13 is an example of an attribute table in a case where an attribute has a point. In the embodiments described so far, it is possible to provide a single elevator with a plurality of attributes if the use floor of the user to which the attribute is added is different. Although a plurality of attributes can be provided, there may be a case where a compound condition such as "reduce the number of stop floors or make the floor empty" is desired as an attribute. In such a case, a score is provided in the car attribute table 35, and each time the car is assigned to a car having an attribute, the score in the car attribute table of the elevator is added or subtracted, and the score is determined to be equal to or more than a predetermined value. When it is, remove it from the assignment. According to the present embodiment, it is possible to handle composite attributes.
