Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control method and apparatus, and more particularly to an improved elevator control method and apparatus during division operation in which a plurality of elevators are operated in service zones divided.

[0002]

2. Description of the Related Art In order to transport a large number of elevator users in a concentrated upward direction from a standard floor, which is often seen during work hours, the elevator service floor is located in a high-rise zone,
It will be divided into low-rise zones, etc., and divided operation will be performed to shorten the time required for one round of the elevator to improve transportation capacity. However,
When boarding from a general floor other than the standard floor during split operation and heading to another zone, it was necessary to transfer elevators at the stop floor common to the high-rise and low-rise zones.

Conventionally, as disclosed in Japanese Patent Laid-Open No. 4-277179, in a division operation in which the service zones of a plurality of elevators are divided and operated, a car call destination call to a non-stop floor is called. It has been proposed to automatically register the destination call to the transfer floor, automatically announce the blinking display of the transfer floor and the notification of the transfer, and make it convenient for the user who needs the transfer. In addition, JP-A-7-69
As disclosed in Japanese Patent No. 544, the call button for disabled persons provided in the car enables call registration for all floors even during division operation, so that there is no need for transit for disabled persons on all floors. There is a service on the floor.

[0004]

The above-mentioned prior art is a measure for improving the usability during divided driving, which is intended only for persons with physical disabilities, and cannot inconvenience general users.

An object of the present invention is to provide an elevator control method and device which are convenient for general users during split operation.

[0006]

The main feature of the present invention is to detect a user's entry into a car other than the standard floor during split operation, and to provide a service when the user's entry is detected. This is to enable the registration of the destination call inside the car with the destination outside the zone.

Another feature of the present invention is that when a division operation is performed and the vehicle stops in response to the hall call on a floor other than the reference floor, registration of a car destination call outside the service zone becomes effective. It is equipped with means.

Still another feature of the present invention is that when a split operation is performed, it stops in response to the hall call on a floor other than the standard floor, and when the user boarding into the car is detected, it is outside the service zone. Is to provide a means for validating the registration of the destination call within the car.

In a preferred embodiment of the present invention, when registration of a destination call outside the service zone is enabled during division operation, means for notifying the fact to the inside of the car and / or the landing is provided.

In the time zone of divided operation or the traffic demand situation, there should be few users who go from the lower floor other than the standard floor, for example, the second floor to the upper floor. Therefore, it can be said that the transportation efficiency as a whole is not impaired even if these limited users are provided with convenience. Therefore, it is possible to improve usability for general users by detecting boarding into the elevator on lower floors other than the standard floor and enabling the destination call to the outside of the service zone (for example, upper floors) by the boarded user. can do. Here, the detection of boarding is not limited to detection by directly increasing the load inside the car or passing through the doorway, but it stops in response to a hall call and a car destination call occurs after that. Therefore, it can be determined that the passenger is a destination call. Further, it is more reliable if the destination call registration is validated under both conditions of the stop in response to the hall call and the detection of the boarding.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will now be described with reference to FIGS.
This will be described with reference to FIG. FIG. 1 is an overall configuration diagram of an elevator control device according to an embodiment of the present invention. In FIG. 1, 1 is an elevator control device, 2 is a group management control device, 21 is an allocation unit in the group management control device, 22 is a load take-in unit in the group management control device, 31 to 33 are elevators 1 to 1.
This is the No. 3 machine control device. 41 to 43 are elevator cars of Units 1 to 3. 51 to 53 are destination call buttons in the car, 61 to 63 are indicators provided in each car, and 71 to 73 are load detection devices provided in each car. 81 and 82 are hall call buttons that are common to all units on each floor, 91 to 96 are hall lanterns (also called reservation lights) for guiding service elevators that are installed at the halls for Units 1 to 3, and 101 to 103 are 1-3 respectively
Indicators on the first floor of the Unit No. 111-113
Are indicators installed at the 9th floor halls of Units 1 to 3, respectively.

In the embodiment shown in FIG. 1, the control device 1 in the elevator machine room is composed of a group management control device 2 and a plurality of machine control devices 31 to 33. Taking the car 41 as an example to explain the elevator car, a destination call button 51 is provided in the car, and the signal of the destination call button 51 is input to the machine control device 31. A hall call button 81 and displays 101 to 103 are provided at the halls on each floor, for example, the hall on the first floor, and these directly input (or output) signals from the group management control device 2. The display 61 installed in the car 41 also inputs a signal directly from the group management control device 2. The hall lanterns 91 and 94, which are other landing guide devices, are configured to input and output signals to and from the group management control device 2 via the machine control device 31 together with the load detection device 71. The wheelchair-only hall call, trolley-use hall call, and underground parking lot hall call may be installed on the same floor.

The group management control device 2 uses the hall calls 81, 8
2), the position and direction of the elevator sent by communication from each unit control device 31-33, the status of the car destination call, and the congestion signal inside the car. The allocating unit 21 allocates to one of the cars in the elevator, and sends an allocation signal to the corresponding machine control devices 31 to 33. The in-car load intake unit 22 of the group management control device 2 takes in the in-car load signal from the load detection devices 71 to 73 (for example, the ratio of the car to the rated load) to the group management control device 2. The unit control devices 31 to 33 perform control such as elevator traveling control and door opening / closing control independent of the unit. In addition, the hall lanterns 91 to 93 are turned on by an allocation signal from the group management control device 2 to guide service elevators to customers waiting in the hall.

FIG. 2 is a diagram for explaining the service zone switching in the case of boarding from the general floor during divided operation according to an embodiment of the present invention. In FIG. 2, <state 1> is a divided operation in which the service zone is divided into the low-rise zone 1st to 7th floors and the high rise zone 7th to 12th floors during work hours when the number of users is from the 1st floor (reference floor). Is being carried out. Now, it is assumed that the user 12 moving from the third floor to the tenth floor appears and registers the ascending hall call on the third floor. In the state 1, it is assumed that, for the ascending hall call on the 3rd floor, the 2nd elevator that can service the earliest among the 1st to 3rd elevators that can be serviced is assigned.

<State 2> is a state in which Unit 2 services the hall call on the third floor and the user 12 gets on the third floor. Upon this boarding, the in-car load detection device 72 of the second car detects an increase in load, and permits destination call registration for all floors including the upper floor zones 8 to 12 which are non-service floors. Therefore, the user 12 getting in from the 3rd floor can register the destination call 10C to the 10th floor, and can head to the 10th floor without the need for transit.

<State 3> is a situation at the moment when the user 12 who gets in from the third floor gets off the car 42 on the 10th floor. At the moment when deceleration starts toward the 10th floor, the driving direction of Unit 2 is switched to the descending direction by the maximum call reversal (HCR) function, and the service in the ascending direction is terminated. Therefore, the second vehicle is again set to the non-service floor on the 8th to 12th floors and returns to the normal division operation.

FIG. 3 is a processing flowchart of an elevator control method according to an embodiment of the present invention. In FIG. 3, in the group management control device 2, it is determined in step 301 whether or not a division operation is being performed, such as during work hours when the number of services in the ascending direction from the reference floor is high. Ends. If it is determined in step 301 that the vehicle is in split operation, it is determined in step 302 whether the current traffic demand is less than a predetermined value. The process of the present invention for improving the usability for the user is not performed, and this process is ended. When it is determined in step 302 that the traffic demand is less than the predetermined value, the process proceeds to step 303, and this time, it is confirmed that the boarding rate on the floors other than the standard floor is less than the predetermined value. If it is determined that the number is large, there is a fear that the original transport efficiency of the split operation may be hindered, and therefore this processing is also ended. If it is determined in step 303 that the boarding rate is less than the predetermined value, step 304
Then, it is determined whether or not the current time is within a preset specific permission time zone. Even when it is determined that it is not in the permitted time zone, this processing is ended. Only when it is determined in step 304 that it is in the permitted time period, step 305 is performed.
Then, the usability improvement measure according to the present invention can be executed.

In step 305, it is determined whether or not the elevator stopped on the floor of the lower zone other than the reference floor has arrived by the hall call on that floor. If the determination result is negative, this process ends. Step 305
If it is determined that the car has stopped in response to a hall call on a floor other than the standard floor, the process proceeds to step 306, and the in-car load data captured by the in-car load capturing unit 22 arrives at the elevator. It is determined whether or not there is a change in the increasing direction at each of the stoppage time and the departure time, and if it is determined that the change has not occurred, it is considered that there is no boarding, and this processing is ended. If it is determined in step 306 that the load in the car has increased in the increasing direction, in step 307 registration of a destination call with the upper zone as a destination is permitted for a predetermined time. That is, the destination call is destined for the upper zone, which is the non-service zone of the elevator, for a sufficient time for the user destined for the upper zone on the floor to operate the destination call button. . Then, in step 308, guidance indicating that the service zone has been changed is displayed on the guidance display devices 61 to 63 in the landing and the car.

Here, the registration of the destination call destined to the non-service zone is made effective only for a predetermined time, but it is also possible to switch the service floor of the elevator to all floors until the driving direction is reversed. It is feasible. In other words, if a car interior destination call with the upper zone as a destination occurs, all can be registered, but in reality, it is unlikely that a lot of car interior destination calls for the upper zone will occur, and operation efficiency will be improved. There is no loss.

In the above embodiment, a plurality of elevators 41 to 43 for servicing floors between multiple floors, hall call devices 81, 82, ... Arranged at the halls, and destination calls provided in each car. Devices 51-53, devices 2, 21 and 31-33 that control the elevator in response to these calls, and multiple service zones for the multiple elevators for a particular time and / or traffic demand. In the elevator control device 1 including the group management control device 2 that is divided into two parts and performs a divided operation, during the divided operation,
Means for detecting stop in response to the hall call other than the standard floor (group management control device 2, step 305)
And means for detecting the user's entry into the car (load detection devices 71-73, machine control devices 31-33)
And means for validating the registration of the destination call destined for the outside of the service zone (upper zone 8 to 12th floor) in response to the operation of both of these detecting means (group management control device 2, machine control device 31). To 33, step 307), and means 71 to 7 for detecting the load as means for detecting the user's entry into the car.
3 and means for detecting that the output of the load detecting means has changed in the increasing direction (machine control devices 31 to 33, step 306). Further, as a condition for validating the registration of the destination call, means for validating when the traffic demand of all elevator users is less than a predetermined value and / or the number of passengers other than the standard floor is less than the predetermined value (group management control The device 2, the machine control devices 31 to 33, steps 302 and / or 303), and means (group management control device 2, machine control devices 31 to 33, step 304) that are effective in a specific time zone during the split operation. There is.

Finally, when registration of the destination call outside the service zone is enabled during the divided operation, means for notifying the fact to the inside of the car and / or the landing (group management control device 2, unit control device 31 to 31). 33, step 308).

Although this embodiment includes many judgment steps, either step 305 for judging that the vehicle has stopped in response to a hall call or step 306 for judging an increase in the load inside the car is omitted. can do.
It suffices to be able to confirm in some form the probability that it is the destination call for the upper zone operated by the user who got in from the lower floors other than the standard floor, for example, the second floor. Also, step 30
It is also possible to omit any or all of 2 to 304.

FIG. 4 is a variation curve of the in-car load which is determined in step 306 of FIG. 3 based on the in-car load to determine whether or not an elevator user has boarded. In FIG. 4, when the load in the car increases between the completion of door opening and the completion of door closing, it is determined that there is a passenger in the elevator. If the load inside the car increases from the time the door is opened to the time it is opened, and the load inside the car decreases from the time the door is opened to the time the door is closed, it is determined that there were passengers and passengers aboard the elevator. If there is no change in the car load between the completion of door opening and the completion of door closing, it is determined that there is no passenger getting on or off the elevator. If the load inside the car decreases between the time when the door is open and the door is open, and the load inside the car increases between the time when the door is open and the door is closed, it is determined that there were passengers / passengers getting off the elevator. If the load inside the car decreases between the time when the door is opened and the time when the door is closed, it is determined that there was only a passenger getting off the elevator. So in this example,
In cases (1) and (2), it is determined that there is a boarding and the registration of the destination call in step 307 is validated.

In this embodiment, the load detecting device in the car is used to determine the user's entry into the car, but a waiting sensor provided at the landing may be used. For example, by capturing the image of the current landing with a video camera and comparing it with the image of the landing after departure from the elevator, it is possible to detect that the number of waiting passengers has decreased and register the destination call in the high-rise zone as if the passenger got on the elevator. It can be valid.

According to the above embodiment, when the service zone of a plurality of elevators is divided into a plurality of divided operations,
It is possible to provide services to any floors for general users who have boarded from other than the standard floor without having to transfer.

[0026]

According to the present invention, during a division operation in which the service zones of a plurality of elevators are divided into a plurality of sections, a user boarding from a place other than the reference floor can go to the floor in the non-service zone without the need for transit. Therefore, an elevator control method or device with improved usability can be obtained.
