Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a group management control device for elevators, and more particularly to a call assignment and reservation guidance system for elevators in which an additional vehicle dispatch guide device is installed on or near an important floor in a building (boarding crowded floor). The present invention relates to an elevator group management control device.

[0002]

2. Description of the Related Art A group management control technique for assigning two or more elevators to hall call registration signals of the same hall of elevators in the same group management group is disclosed in, for example, Japanese Patent Laid-Open No. 58-95081. Reassign when expected arrival elevators are full as described.
In JP-A-55-26103, a predicted waiting time required for an elevator assigned to a registered hall call to arrive is calculated, and if it is equal to or greater than a predetermined value, another elevator is called for that hall call. What is additionally allocated is disclosed. Further, it is known that the judgment is made by the output of a device that measures the degree of crowdedness of a hall as the degree of crowdedness of the hall, the departure from a full capacity, the reservation of an event, or the cancellation of a set time zone.

In Japanese Patent Publication No. 54-37744, a special hall call registration device is provided in order to call in an elevator with a small number of passengers, and a service in which the degree of elevator boarding is more important than waiting time is possible.

Further, Japanese Unexamined Patent Publication No. 4-197969 discloses a technique that takes into account the horizontal distance of elevators assigned as a hall call registration device, that is, a technique that assigns an elevator near the position where a hall call occurs. There is.

[0005]

SUMMARY OF THE INVENTION The above-mentioned prior art is based on the number of additional allocations according to the crowded floor on arrival at the hall where the call is registered, the estimated waiting time, the traffic demand state, and the detection value of the number of people waiting on that floor. However, the additional allocation function reflects the user's intention, such as the judgment of the elevator user, various personal feelings of congestion, and consideration of the situation when using luggage, etc. It does not have the function to

In the prior art, a special elevator call registration can be performed by the user's will, but the hall registration device must be different from a general hall call registration device, and group management is required. No consideration is given to the transportation capacity and traffic demand of the entire elevator, or the time of use, and abuse in particular when the elevator is crowded poses a problem.

Further, in the prior art, the elevators close to the operated hall call registration device can be preferentially assigned while considering the operating efficiency of the group-controlled elevators as a whole, which is convenient for the user. It is possible, but it is impossible to call the second and subsequent elevators of the elevator user.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to respond to hall calls on the same floor depending on the total transport capacity of group-controlled elevators and the traffic demand situation on each floor. The automatic allocation of two or more elevators is permitted automatically, and the elevators can be additionally allocated on the floors that have been approved at the discretion of the elevator users in the hall, making each user extremely satisfied. It is to provide an elevator group management control device that is highly frequent and does not cause wasteful operation.

[0009]

In order to achieve the above object, the present invention inputs and outputs a plurality of hall call registration devices to the same hall and a plurality of hall call registration signals from the hall call registration devices. The call signal registration device and the status of congestion of each floor that is the target of group management, the traffic demand of the elevator, the current time, and the function of determining whether the registered hall call signal belongs to a specific floor The determination device, the call allocating means having the function of newly allocating an elevator to the same floor, and the guide notification means for notifying the user that an elevator can be newly allocated to the same floor It is configured.

[0010]

When a hall call occurs, the situation determination device needs to newly assign an elevator to the same floor in consideration of the current traffic demand, time, etc. after assigning one elevator. Or not. For example,
If there is a large demand for boarding traffic and a preset permission time zone is set, a new elevator call allocation will be permitted for hall calls in the same direction on the same floor. In other words, at the peak of elevator use, passengers who are assigned due to the congestion situation of the car and the congestion situation of the hall and decide that it is not possible to get by the elevator with the service guidance alone will operate another elevator by operating the hall call button. It can be additionally allocated.

Also, as in the dining room floor in the latter half of lunch time, there is a hall call on the floor where congestion is clearly generated after a predetermined time,
Even if the traffic demand is small, if a preset hall call on a specific floor is set, a plurality of call assignments are permitted from the beginning. At this time, if an elevator close to the hall call button where the call is generated is assigned, the convenience of the user is further improved.
This call assignment method is preferred for users who have wagons and baggage at hotels and the like because they do not need to ride a crowded car forcibly.

As described above, when a hall call registration device registers a hall call, the response light of the hall call registration device is turned on, and if the assignment of another elevator is permitted, either The response is turned off or blinked to inform that the call can be made. In addition, as the method of notification, voice guidance to the hall or guidance using the display panel, or when multiple hall call registration devices are installed in the same floor and in the same direction, the elevators already assigned However, the answer lamps of the call assigning device excluding the nearest answer lamp may be erased or turned on.

The case of being managed based on S) will be described as an example.

Therefore, the start of this program can be freely started from the system timer or from another program.

FIG. 4 is an overall processing flowchart of the operation control program SF10.

The operation control program SF10 is started after the power is turned on or by restarting. First, in the initial processing E10, the elevator control data table SF11
Performs initial processing such as clear processing.

Next, steps E15 to E60 are repeatedly executed until the power is turned off or the program or more occurs, and the group management control is executed.

That is, at step E15, the elevator operation mode is selected according to the traffic demand mode and the current time obtained at the previous step E35 and the SF21 conditions such as a preset rule table. This will clarify the floor and processing conditions for additional allocation.

In step E20, signals of hall call buttons of all hall call registration devices on all floors are input and set in the hall call button input table of the hall call table SF12. This is input hall call registration and reset processing, hall call button input table XHMDT
Create (m, j, i). Further, it outputs a command to turn on / blink / turn off the response lamp for the hall call and the contents of the hall call response lamp table YHMDT (m, j, i).

In step 30, the machine control devices 20 to 2
The communication data from No. 3 is stored in the elevator control data table SF11. Also, the allocation hall call table HDT (k, j, i) and the like are transmitted to each car.

At step E35, the mode of the current traffic demand is identified, and according to the result, the additional allocation control method for each floor at step E37, the condition for congestion determination, and the rule for hall call allocation at step E50. Is used to determine the status of the entire usage in step E15.

In step E40, a permission flag setting process for additional allocation is performed.

In step E50, hall call allocation processing is performed, and in step E60 elevator services such as control contents and arrival guidance currently being performed, notification of additional allocation permission, and building guidance from the building management device 12 in some cases. Information guidance processing is performed.

Next, the processing of step E20 of the overall processing flowchart of FIG. 4 will be described in detail with reference to FIG.

First, in step E201, input processing from the hall call registration device 11 is performed to create a hall call button input table XHMDT (m, j, i).

From step E202 to step E206, the hall call answer lamp, lighting, blinking, and extinguishing processing are performed, and E
Reset processing is performed from 207 to E210. Step E
In 204, the elevator near the elevator for which reservation information is displayed will be continuously lit, and the distant unit will blink and the second
Value of each additional allocation permission hall call table HA
Set to PT (m, j, i). Here, the variable m indicates the number of the hall call registration device attached in the horizontal direction.
A loop process is performed from E202 to E211 until all hall calls are processed.

FIG. 6 is a detailed flowchart of the additional allocation permission flag setting process in step E40 of FIG.
The additional allocation flag is set and cleared by the E401 to E410 loop processing based on the time of the table of possible additional allocation of SF21, available hall call data, elevator traffic demand, and operating status, and the additional allocation permission table HDT (k, j, SF11 of SF11 is set. Create i). SF2 calls specific calls that enable additional allocation regardless of traffic demand and time of day.
It is also possible to set by 1.

FIG. 7 is a detailed flowchart of the hall call assignment process of step E50 of FIG.

Step E501 sets the number of repetitions of the inner loop process of the process of step E50, and the loop variable is n. Steps E502 to E50
Step 4 determines whether or not the newly input hall call input has already been made to the hall call button for accepting the additional allocation. Step E505 is a backup process for preventing a decrease in overall operation efficiency due to excessive additional allocation, and if the already allocated units are sufficient, the mode is switched to the mode in which additional allocation is not performed at step E510. A step E505 predicts and determines whether or not the passengers in the group-managed elevator upon arrival at the hall will reach a predetermined value, for example, 35% or more of the car capacity. In step E506, the elevator is selected by the second allocation method for hall calls for additional allocation. Here, except for the assigned elevators, the elevators closest to the hall call button in the arrangement n are preferentially selected.
Further, here, in addition to the traffic demand and time, whether or not the hall call belongs to a specific floor, or the predicted value of the number of people in the car at the time of departure of the floor may be used to make a re-determination by the situation determination device. good. At step E508, the finally selected elevator is assigned to the hall call, and notification control such as reservation guidance is performed by the hall display device, the hall voice guidance device, and the hall alarm device for each machine. In step E509, the loop variable n is checked to determine the end of this routine. When it is determined in step E503 that the call is a new hall call, an elevator is selected using the first call assignment method for assigning a new hall call in step E507.

In this way, by making it possible to call a plurality of elevators on the same floor, the convenience of the user at a busy time or on a specific floor is improved.

FIG. 8 shows a display example of the display device in the hall on the fifth floor of this embodiment. Here, the time is assumed to be the building where the dining room floor at the first half of lunch is on the top floor. In the first half of lunch, the elevator is expected to be congested, so it is an additional allocatable time zone in SF11, and since the dining room floor is the top floor, only the UP hall call can be reassigned. 8a to 8 of the hall display device 14 installed in the hall
The time d, the position of the car, the direction of travel, the degree of congestion in the car, and the like can be displayed, and the degree of congestion in the car indicates that the further the display is to the left, the more crowded. Now, UP, D on the 5th floor
When the hall call button is pressed for both the OWN and the UP call, the third vehicle that can respond earliest is assigned and the reservation lamp 7c is turned on. Similarly, the second call is assigned to the DOWN call and the reservation lamp 7b is turned on. At this time, the congestion degree in the car of Unit 3 is 70%, and the additional allocation permission flag is set based on the learning result that there are many passengers heading from the 5th floor to the upper dining floor, and the 1st unit to be additionally allocated is near. The UP hall button response lamp of 6a blinks. As a result, the queue and congestion in front of Unit 3 are divided into two, and some people move to Unit 1 to request the allocation of the second unit by operating the hall call button. Also, by using the voice guidance device 13, "Please press the hall call button. ], Which means that additional allocation is possible, is performed as in the notification examples (d) to (f). Further, the display can also be a flow display shown in FIG. In this way, when the UP hall call button is pressed, the fourth closest vehicle next to the third one is assigned and the 7d response light is turned on. In addition, even if passengers get in the second floor on the 6th floor and the congestion increases, additional allocation is not permitted because the DOWN direction call is not a floor that can be additionally allocated. In this way, additional allocation is automatically set based on the time of day, traffic demand, and elevator operation status, and the execution is left to the passenger's judgment. Only additional calls can be assigned, and efficient call assignment can be performed. Although this example has been described in the office building, as described above, the convenience of the user can be improved even in a hotel or the like by changing the conditions of this additional allocation permission.

[0038]

According to the present invention, the addition and allocation permission can be automatically set according to the operating efficiency of the elevators under group management control, traffic demand, etc., and it can be notified that additional allocation is possible. Therefore, additional allocation can be executed at the discretion of the user, and at the time of congestion when the transportation capacity of the elevator is required, the minimum required number can be serviced on the congested floor and there is a margin in the transportation capacity. Even in such a case, an elevator can be additionally allocated only in a specific time zone and a specific floor, which has the effect of improving the serviceability for users.
