Abstract

PROBLEM TO BE SOLVED: To control a hospital building elevator such that it can be operated without producing longer waiting time. SOLUTION: An elevator controller is controlled so as to stop plural cars 1a, 1b,..., in their local operation at every floor always at substantially constant intervals, by detecting the cars with car location detector means, searching on the basis of the location information about the cars whether there is a car following the preceding car within a predetermined interval or not with a constant-interval operation maintenance means 8, and to the car the answer thereof is yes then constraining the door of the car thus searched for opened for a fixed period to delay the departure thereof. the controller thus stops elevators at every floor at substantially constant intervals in a building where car calls are requested so frequently that the waiting time is hardly shortened, to thereby prevent excessively longer waiting time, which the existing optimum allocation control never completely prevents.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an elevator control device.

[0002]

2. Description of the Related Art Conventionally, for a plurality of elevator cars serving multiple floors, when a hall call is generated from a landing on a certain floor, the position, direction, call allocation status and other various information of each car are considered. An elevator control device that performs group management control for selecting and responding to an optimal car is widely used. Such an elevator control device that performs conventional group management mainly targets a general office building or a hotel.

For example, in a general office building, operation control is performed in consideration of improvement in transportation capacity and reduction of waiting time, such as in the morning work time zone, the evening leaving time zone, and the lunch time zone. When traffic demand increases, or when traffic decreases at night or on holidays, etc., efficient operation is performed by switching to a preset operation mode in accordance with traffic changes unique to the building. In condominiums, contrary to general office buildings, traffic demand goes from each floor to the base floor in the morning, traffic from the base floor to each floor increases in the evening to night, and traffic decreases at night and on holidays. Efficient operation is achieved by switching to a preset operation mode in response to traffic changes unique to the building.

Further, in the case of a hotel, in order to allow a sense of comfort even if the waiting time is slightly longer, consideration should be given to preferentially allocating an empty elevator car, or a check-out period in the morning. When the traffic demand increases during the check-in time in the evening or in the evening, efficient operation is performed by switching to a preset operation mode according to the traffic change specific to the hotel.

On the other hand, hospitals in recent years have large facilities,
Buildings tend to be large, and a group management control elevator is required. However, in buildings for hospitals, elevator users are not only hospital-related, such as doctors and nurses, but also outpatients, inpatients, visitors, etc.
The purpose of use also varies. For example, in the case of hospital staff, people who are physically handicapped, who are transporting medical equipment, and who are from the outside, There is always demand throughout the hours, such as going into and out of hospital wards for visits, and demand does not always increase in a certain direction during work hours or other certain hours as in the office building described above. The feature is that the demand of the whole building has reached the peak.

[0006]

In such a conventional group management control elevator, the number of baskets does not satisfy the traffic demand, especially in a building having a high demand over all floors such as a hospital building. If there is enough, there is a problem that the waiting time from arrival at the landing to arrival of any car, that is, the average unanswered time becomes long.

This is because the group management control for general office buildings is characterized by the fact that there is a peak time zone in the traffic flow, and the ratio of users who flow in a certain direction increases during high demand. However, it is possible to take an operation pattern according to the demand, but there is no demand floor in a fixed floor and a certain direction in a hospital building, and the demand in both directions reaches a peak in all floors. Therefore, it is difficult to take measures to strengthen demand in a certain direction, and due to restrictions on the purpose of use, it is not possible to make measures to increase operation efficiency by making some floors non-stop floors, making it possible to wait long. This was because there was no way to improve the traffic efficiency of the entire building in response to the user's complaint.

[0008] The present invention has been made in view of such a conventional problem, and when the demand of the entire building is so high that the waiting time cannot be reduced, the elevators are dispatched at regular time intervals. The elevator arrives at the landing on each floor within a certain period of time, preventing extreme long waits that could not be prevented by conventional optimal allocation control,
An object of the present invention is to provide an elevator control device capable of improving a psychological service.

According to the present invention, when the demand is high in the whole building such that the waiting time cannot be shortened, the users of the elevators are distinguished and the priorities for allocating the elevators according to the purpose of use are determined. An object of the present invention is to provide an elevator control device that performs group management control that can improve service.

[0010]

According to a first aspect of the present invention, there is provided an elevator control apparatus for performing group management control for selecting and allocating an optimum car from a plurality of cars to a hall call. Each floor stop operation control means operating in each floor stop operation pattern, a car position detection means for detecting the position of each of the plurality of cars, and a preceding car based on the position information of each of the plurality of cars detected by the car position detection means. An equidistant operation maintaining means for restraining a car approaching the car to a predetermined distance for a predetermined time when the door is opened and delaying departure is provided.

In the elevator control apparatus according to the first aspect of the present invention, when each floor stop operation is performed, the position of each of the plurality of cars is detected by the car position detecting means, and based on the position information of each of the plurality of cars. Searching for a car approaching a predetermined distance with respect to a preceding car by an equal-interval operation maintaining means, and restraining a car approaching a predetermined distance to the preceding car for a predetermined time when the door is opened. The car is controlled so that each car always runs at approximately equal intervals and stops at each floor.

Thus, when the demand of the entire building is so high that the waiting time cannot be shortened, the elevators arrive at each floor at substantially constant time intervals, and are extremely difficult to be prevented by the conventional optimal allocation control. Prevent the occurrence of long waits.

According to a second aspect of the present invention, in the elevator control apparatus of the first aspect, there is further provided an operation pattern time limit switching means for switching the operation pattern from the group management control operation to each floor stop operation pattern for a predetermined time period. Therefore, according to the time transition characteristics of the elevator demand of the building in which this device is installed, the operation is performed by the group management control during the normal time zone, and the demand in the entire building is such that the waiting time cannot be reduced. Automatically switches to the operation in each floor stop operation pattern according to the high time zone.

According to a third aspect of the present invention, there is provided the elevator control device according to the first or second aspect, further comprising a notifying means installed at each landing to notify a car arrival time interval during operation in each floor stop operation pattern. This informs the landing user of the waiting time.

A plurality of different types of hall call buttons, and allocation control means for selecting and allocating an optimum car according to the priority in accordance with each of the plurality of types of hall call buttons.

In the elevator control apparatus according to the fourth aspect of the present invention, by operating each of a plurality of types of hall call buttons having different priorities installed at each floor, the allocation control means can select an optimum car according to the priorities. By selecting and assigning to hall calls, the waiting time varies according to the urgency of the hall users, and priority is given to the allocation of hall calls for users with high urgency in particular, and the uniqueness of traffic demand Corresponding.

According to a fifth aspect of the present invention, in the elevator control device of the fourth aspect, a plurality of types of hall call buttons having different priorities are prepared for hospital staff, outpatients, and patients, and the priority is given in this order. This gives a priority to responding according to the purpose of use of the hall users, starting from the most urgent use and responding to hospital personnel such as doctors and nurses with high urgency. It can respond to use, use for emergency transportation, etc. with a short waiting time, and is particularly suitable for hospital buildings.

According to a sixth aspect of the present invention, there is provided the elevator control device according to the fourth or fifth aspect, further comprising a notifying means installed at each landing to notify the user of the arrival of the arriving car.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows, as an elevator control device according to a first embodiment of the present invention, an elevator control device (here, three elevator cages) for three elevator cars 1a, 1b, and 1c serving n floors from the first floor to the nth floor. However, the number of installations is not particularly limited). The elevator control device according to the first embodiment includes a single control device 2a, 2b, 2c for individually controlling each car 1a, 1b, 1c, and a single control device 2
a, 2b, 2c, and a group management control device 3 for performing group management control. The elevator hall has a hall call button 111,
, 11n, and outputs a detection signal to the group management control device 3 in response to the operation of these hall call buttons 111, 112,. The input / output control devices 121, 12 for receiving the call reception signal and lighting the call generation floor buttons among the hall call operation buttons 111, 112,.
2,..., 12n are also provided.

The single control devices 2a, 2b, 2c are respectively provided with door control units 5a, 5b, 5c for opening and closing the doors of the elevator cars 1a, 1b, 1c and a car position detecting unit 6a for detecting the car position. , 6b, 6c. In addition, the group management control device 3 selects a selection logic registered in advance for a hall call on a certain floor based on the hall call registration status and the car call registration status of each car, car position information, driving direction information, and the like. A car allocating unit 7 for selecting and allocating an optimum car according to a program, and a group management control operation as a normal operation pattern and a traffic demand of an elevator exceeding a certain level detected by an external input switching signal. There is provided an operation pattern control unit 8 for switching between each floor stop operation for stopping on each floor and controlling the operation interval so that the distance between the cars becomes equal at the time of each floor stop operation.

Next, the operation of the elevator control device having the above configuration will be described. The normal group management control operation is the same as the conventional operation. When a hall call is generated on a certain floor and input to the car allocating unit 7, the car allocating unit 7
2b, 2c, the car call registration state, the driving direction information of each car, the door opening / closing state, the already assigned hall call registration state, each car position information a, etc. A car of the car is selected, and an assignment signal b is given to the selected car so as to respond to a newly generated hall call.

As shown in the flow chart of FIG. 2, when a command to switch to each floor stop operation control pattern is given by an external input (step S11), the operation pattern control unit 8 issues a command to switch the operation pattern to each floor stop operation pattern, as shown in the flowchart of FIG. c is given to each single control device 2a, 2b, 2c, and each single control device 2a, 2b, 2c calls a landing,
The control is switched to a control for stopping each of the cars 1a, 1b, 1c on each floor irrespective of the car call (step S12).

In each floor stop operation, the operation pattern control section 8 inputs the car position signal a from the car position detection sections 6a, 6b, 6c of the single control devices 2a, 2b, 2c (step S13), It is determined whether or not the car position is within a certain distance (step S14). If there is a car position between the cars within a certain distance, the operation pattern control device 8 determines that the corresponding car on the rear side is a single car. A car restraint command signal d is transmitted to the control device (step S1).
5).

On the other hand, the individual control devices 2a, 2b, 2c perform each floor stop operation based on the flowchart of FIG.
That is, when each floor stop operation command c is received (step S
21), each unit control device 2a, 2b, 2c is called a car,
An operation of stopping the cars 1a, 1b, 1c one floor at a time regardless of the hall call is performed (step S22). During this operation,
The car position signal a detected by the car position detectors 6a, 6b, 6c is always output to the group management controller 3 (step S23).

Unless the restraint command d is received from the group management control device 3, the individual control devices 2a, 2b, 2c continue the floor stop operation (step S24). However, when one of the single control devices receives the restraint command d from the group management control device 3 (step S24), the single control device that has received the restraint command d opens and closes the basket controlled by the own device when the door is opened and closed. (Step S26), restraint control for delaying departure by keeping the door open for a certain period of time or more is performed, and the distance between the cages is adjusted to be substantially equal again (steps S26 and S27).

Thus, according to the first embodiment,
In particular, when demand is peaking without any vertical direction on each floor regardless of the time zone, such as in a hospital building, each car should be stopped at each floor and the intervals between each car should be approximately equal. When there is a car approaching within a predetermined distance, when the car stops on the floor where the car is located and opens and closes the door, the door is closed for a fixed time by performing control to delay the closing time from the normal set time, By making adjustments to increase the distance from the car to be carried out, operation control is performed so that any car arrives on each floor at almost constant time intervals, and psychological Service can be improved.

In the first embodiment, a time limit timer is provided in the group management control device 3 instead of switching between the normal group management control operation and each floor stop operation manually from outside by an administrator. It is possible to set a time zone for switching to each floor stop operation in advance, and to automatically switch to each floor stop operation at that time zone, thereby imposing a burden on the elevator administrator to switch the operation pattern. Can be reduced.

Next, a second embodiment of the present invention will be described with reference to FIGS. The feature of the second embodiment is that the average arrival time for the elevator control device of the first embodiment shown in FIG. 1 and the display device installed at each landing at the time of each floor stop operation control. It has a function to display the interval. Therefore, the second embodiment is characterized in that the display devices 131 to 13n are installed at appropriate positions in each hall, for example, near the hall call button or above the elevator door as shown in FIG. In addition, the group management control device 3 is provided with a display device control unit 9 so that the average arrival time intervals calculated by the operation pattern control unit 8 are displayed on the display devices 131 to 13n of each floor. Since most of the components of the second embodiment are common to those of the first embodiment shown in FIG. 1, the same components are denoted by the same reference numerals.

The operation pattern control unit 8 of the group management control device 3
The calculation of the average arrival time interval is performed according to the flowchart of FIG. That is, if there is a floor stop operation command (step S31), the average arrival time is determined based on the number of elevators n, the number of building floors G, the elevator speed V, and the building floor distance D registered in advance in the storage unit (step S32). The time interval T is obtained by, for example, the following equation and given to the display device control unit 9 (step S33).

T = 2 (G-1) .D / V The display controller 9 outputs a signal e indicating the average arrival time interval T to the display devices 131 to 13n of the floors for display (step S34). ).

Thus, in the case of the second embodiment, the hall user can know how long to wait for the next elevator to arrive, so that the frustration caused by long waiting can be eliminated and the service can be improved.

In the second embodiment, instead of displaying the average arrival time interval by the display device at each floor, or by using a voice synthesizing device together with the display, the average arrival time interval is reported. be able to.

Also in the second embodiment, the time period for switching between the group management control operation and each floor stop operation is automatically performed by the timed timer, thereby reducing the burden on the elevator administrator. be able to.

Next, an elevator control apparatus according to a third embodiment of the present invention will be described with reference to FIGS. The elevator control device according to the third embodiment includes a plurality of types of hall call buttons 211; 221; 231, 212; 222; 232 in which each floor has a difference in priority.
.., 21n; 22n; 23n are installed, and the elevator car assigned according to which type of hall call button is pressed is differentiated so that a quick response to a high-priority hall call can be made. And the following configuration is provided.

Each of the single control devices 2a, 2b, 2c,... Performs operation control for the elevator car 1a, 1b, 1c,..., And operation control for the hall call response command from the group management control device 3. In addition, it has a function of transmitting the car call status of its own device, car position information, and the like to the group management control device 3.

The group management control device 3 determines the type of a hall call when a hall call is made from an arbitrary floor by a hall call button, and determines an optimal response car according to the assignment priority and assigns it. And the individual control devices 2a, 2b,
A car allocating unit 7 'is provided which controls to give a response command to the corresponding one of the cars 2c,.

As a plurality of types of hall call buttons installed at each hall, here, hall call buttons 211 to 21n for hospital-related persons such as doctors and nurses for hospital buildings, and hall call buttons for outpatient visitors Three types, 221 to 22n and inpatient hall call buttons 231 to 23n, are installed at each floor hall.

The response assignment logic for the three types of hall call buttons registered in the car assignment section 7 'of the group management control device 3 is based on the following priorities 1-3 in consideration of the urgency of the response.
Is set.

Priority 1: Hospital hall call button 2
A car which can respond fastest is selected and assigned to 11 to 21n.

Priority 2: For the outpatient visitor hall call buttons 221 to 22n, select the car that can respond earliest among the car numbers other than the car assigned by the hospital staff hall call button. assign.

Priority 3: Inpatient hall call button 23
For Nos. 1 to 23n, select and assign the car that can respond the earliest among the car assigned by the hall call button for hospital staff and the car assigned by the outpatient visitor hall call button. .

Next, the operation of the elevator control device having the above configuration will be described. As shown in the flowchart of FIG. 7, when any of the three types of hall call buttons is pressed on a certain floor to generate a hall call (step S41),
The car allocating unit 7 'of the group management control device 3 first determines the type of the hall call from the hall call input signals f, g, h by using the hall call button with the hall call button for hospital staff or the hall call button for outpatient visitor. It is determined whether the hall call is g or the hall call h using the inpatient hall call button, and the result is saved (step S42).

In order to select a car which can respond to the generated hall call earliest, the predicted arrival time of each car is calculated, and the calculation result is saved for each car (steps S43 to S45). The calculation of the estimated arrival time is based on the car position information from each of the single control devices 2a, 2b,.
The process is executed based on the car call registration status registered in the car call registration table by the newly generated hall call registration table and the hall call registration status registered in the hall call registration table.

FIG. 8 shows a car call registration table. This car call registration table indicates that the elevator
To H, and the elevator service floor has 64 floors from 1 to 64 floors.
Non-registration turns on / off each bit of this car call registration table.
It is discriminated by off, and if registered, it is turned on, if it is not registered, it is turned off, and it has been responded and turned off. Therefore, the car call registration status of each car is determined by counting the number of on-bits of each car.

FIGS. 9 (a) and 9 (b) show an upper hall call registration table and a lower hall call registration table, respectively. Like the car call registration, an upper hall call is assigned to an elevator of a certain car. When the upper hall call registration table is turned on, the floor of the floor where the upper hall call was generated, the intersection position bit of the assigned car is turned on,
Similarly, for the down hall call, the floor where the down hall call occurred in the down hall call registration table,
The hall call registration is performed by turning on the bit at the intersection position of the assigned car. In addition, at each intersection position, a bit area indicating which of the priorities 1 to 3 the hall call registration belongs to is also provided. Therefore, the registration status of the hall call is determined by counting the number of hall call assignments of each car by referring to the hall call registration table, and the hall call type is identified by data in the priority bit area.

If the estimated arrival time is calculated and saved for all the cars (step S43), next, which of priority processing 1 to priority processing 3 is to be performed based on the type of the hall call button that has made the hall call. A determination is made (step S46).

Priority processing 1: In the case of the hall call f using the hall call button for hospital staff, the car which can respond the earliest is selected based on the estimated arrival time of each car calculated in step S44. Then, a response assignment signal b is output to the single control device of the unit (step S47).

Priority processing 2: In the case of the hall call g by the hall call button for the visitor with the second highest priority,
Based on the estimated arrival time of each car calculated in step S44, the car is searched in order from the car that can respond at the earliest time, and a car which has not been registered with a hall call of priority 1 is selected, and a car of that car is selected. Response assignment signal b for single controller
Is output (step S48).

Priority processing 3: In the case of the hall call h by the in-patient hall call button, retrieval is performed in order from the car that can respond first based on the estimated arrival time of each car, and the priority is 1 among them. A car for which no hall call registration and a priority 2 hall call registration have been made is selected, and a response assignment signal b is output to the single control device of that car (step S4).
9).

Further, in the next step S410, it is determined whether or not a response to a lower priority car call has already been allocated to a car to which a response has been allocated by the priority processing 1 or 2 in particular. If there is such an assignment, the low priority car landing call assignment is forcibly canceled. Then, for the hall call for which the allocation has been canceled, the re-allocation processing is performed by the processing of the priority processing 2 or 3 (step S411).

Thus, according to the elevator control apparatus of the third embodiment, the user is identified from the type of the hall call button, and the hall call of the user with high urgency is given priority over the hall call. By performing call response assignment, the efficiency of elevator operation through group management control can be increased, and emergency responses can be flexibly handled, and services can be provided that respond to the special characteristics of traffic demand.

In the third embodiment, a plurality of types of hall call buttons are installed at the elevator halls on each floor. Instead, only one type of hall call button may be provided, and a high-priority hall call button may be provided. It is possible to set so that a user who has the right to do the call registration can perform a hall call registration with a higher priority than a general user by a special operation procedure. For example, it is possible to adopt a method of repeatedly pressing a button from a certain number of times within a certain period of time, a method of continuously pressing the button for a certain period of time or more, and the like. Can be registered at a high level, and the usability is improved. In addition, for a user with high priority, a method of registering a hall call using an ID card can be adopted.

In addition, instead of three priorities, the priority may be limited to two for hospital personnel and general users, or may be set to four or more.

Next, a fourth embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. A feature of the elevator control device according to the fourth embodiment is that, as in the elevator control device according to the third embodiment shown in FIG. 211; 2

0b1,..., 10bn;..
For example, the single control devices 2a, 2b,... Which are installed near the hall call button or above or on the side of the elevator door and assigned a response are displayed on the display installed on the floor call generation floor. The point is that a display indicating the priority is performed.

Therefore, in the elevator control device according to the fourth embodiment, the car allocating unit 7 ″ of the group management control device 3 uses the hall call buttons 21i, 2 having different priorities on a certain floor i.
When either 2i or 23i is pressed, the landing call signal f, g, or h is received, and response assignment processing based on the same priority as in the third embodiment is performed, and the car which has determined the response assignment is executed. Command c to the single control device
And a function of transmitting a user identification signal j. When the individual control devices 2a, 2b, 2c,... Receive the response command c and the user identification signal j, when the elevator car of the corresponding car stops on the floor where the hall call occurred and the door is opened, .. Are provided to output a display signal k to the display device to display a user identification indicating which user the current response is for. In the fourth embodiment, the other components are the same as those of the elevator control device according to the third embodiment shown in FIGS. 6 to 9, and therefore, the same components are denoted by the same reference numerals. It is shown with a.

Next, the operation of the elevator control apparatus according to the fourth embodiment having the above configuration will be described. Any floor i
From three types of hall call buttons 21i, 22i or 23
When any one of i is pressed and a hall call occurs, the car allocating unit 7 ″ of the group management control device 3 performs a response allocation calculation in consideration of the priority order based on the flowchart of FIG. 7 similarly to the third embodiment. Is executed to determine the response assignment to the most suitable car, and the corresponding car (here, car A; the same applies hereinafter)
Outputs a response command c to the single control device 2a, and the single control device 2a receiving the command causes the elevator car 1a to respond to the registered car call while the floor call is newly registered. It moves to i and the door is opened and closed.

When the elevator car 1a arrives at the floor i where a new hall call has occurred, the response car display device 4a of the single control device 2a displays the response of the current user to any user according to the flowchart of FIG. The display 10ai indicates whether the request is for a hall call. That is, when the vehicle stops in response to the assigned floor (step S51),
It waits for the door to be opened (step S52). When the door is opened, the display signal 10ai indicates which user's call has been answered on the display 10ai based on the user signal j from the group management control device 3. And the display 10ai corresponds to the display signal k from among the display examples registered in advance,
For example, (1) "I am in a hurry, please use only hospital staff", (2) "This elevator can be used only for visitors," (3) "Everyone can use it" Is displayed (steps S53, S53).
