Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to group management control of elevators, and in particular to group management that allows each user to be assigned an optimal elevator for service. This invention relates to a control elevator system.

(Prior art) It has been a long time since microcomputers appeared in this world.
Its applications continue to expand in various industrial fields.

And its benefits are immeasurable.

It is no exaggeration to say that it plays a part in the information and communication society that has become a hot topic of conversation recently.

The construction industry is no exception, and not only does it focus on building taller buildings, but it also strives to construct buildings that are fully equipped with information and communication-oriented equipment.

In the information and communication buildings that are emerging against this background, not only the living spaces but also the exchange of information between floors has been dramatically improved.

Nowadays, as the number of such modernized buildings increases, a method of servicing one floor with multiple elevators installed side by side is used as a transportation system to smoothly handle traffic between floors of the building. In order to efficiently operate each of these elevators installed in parallel, the mainstream is a group management control method that comprehensively controls all elevators. This is management control, and the purpose is to promptly select a service elevator for elevator users at a landing and have them arrive at the landing.When an elevator user presses the hall call button to register a hall call, the service elevator is immediately activated. It is also called the instant lighting method because it determines the location of the elevator on that floor and lights up the forecast light (hall lantern) of the determined elevator on that floor to notify the user and prompt the user to move to the elevator location. With the advent of this method, inter-floor traffic with multiple floors has been improved, and it is becoming established as an elevator control method in high-rise buildings.

In group management control, in order to improve the operating efficiency of multiple elevators (multiple elevators) installed in parallel and to improve service to elevator users, a small computer such as a microcomputer is used to control the answering machine for hall calls in the hall on each floor. Allocate reasonably and promptly using In other words, when a hall call occurs, the elevator that is most suitable for handling the hall call is selected and assigned as the elevator that responds to the hall call at an early stage.
Other elevators will not be allowed to respond to the hall call. Conventionally, the method used to select this assigning machine is to predict which elevator will arrive first at the floor where the hall call occurs, and then assign the hall call to that elevator.This method is considered to be the best. There is. Therefore,
Various methods have been devised to predict which elevator will arrive first. For example, by calculation, the predicted time for each elevator to arrive at each floor is calculated, and based on the magnitude of this value, it is determined which elevator will arrive first. Predicting the elevator. Then, the hall warning light on the floor where the hall call has occurred in the assigned elevator number is turned on to inform the user of the service elevator.

In such instant-lighting group management control, the group management control microcomputer detects newly generated hall calls by, for example, searching all halls in fixed time units, and detects newly generated hall calls. When there is a hall call (hereinafter referred to as a new call), a predetermined service elevator selection logic determines the optimal elevator from among all the elevators, and lights up the hall forecast light for that elevator.

Therefore, the elevator selection logic is activated every time a new call occurs, and this elevator selection logic includes various prediction logics (e.g., fullness prediction, car call first-come-first-served prediction, long-life prediction, etc.) to improve prediction accuracy. .

In such a group management control system, if the elevator assigned to a hall call is unable to respond to a hall call due to some abnormality, or if the elevator arrival time for a hall call increases due to a sudden change in building demand, The elevators are being reassigned to other elevators and put into service.

In this case, the warning light indicating the elevator assignment status must also be changed. When the forecast is changed, elevator users who were waiting in front of the assigned elevator have to move to the newly assigned elevator, which confuses the users when the hall is crowded. Furthermore, if there are a large number of passengers waiting at the platform, even if the forecast change elevator arrives, the passengers may not be able to board the elevator and may be left behind.
This caused discomfort to elevator users.

(Problem to be Solved by the Invention) In this way, in the conventional group management control system, the notification of the change in the allocation of elevators for a single landing call is targeted at elevator users of 1 Å or more. Some customers couldn't get into the elevator,
This leads to a decline in service.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a group management control elevator system that allows each user to specify the elevator number to be used, thereby improving service.

First, an elevator user specifies a destination floor using a mobile card 1 and approaches an elevator hall (STI). Of course, the elevator user may specify the destination floor after approaching the landing. The mobile card 1 adds its own card identification code to the destination floor code input by the elevator user and transmits it as a radio wave (Sr2).

The sensor panel at the hall receives the radio wave from the mobile card 1, that is, the floor code of the first destination and the card identification code, and outputs it to the elevator control unit 30 (Sr1.4). Then, the elevator control unit 30 determines the floor to be serviced by the elevator and its direction based on the input destination floor code and the installation floor of the sensor panel that gave the received data, and also stores the card identification code. (Sr5). Next, an elevator to be put into service on the service floor is determined and operated, and the identification value of the elevator is output as a display code to the previous sensor panel (source of the destination floor code) (Sr6).

Furthermore, the necessity of changing the assignment is examined for hall calls for which elevator assignments have already been made, and if necessary, the elevator to be changed is determined and outputted to the sensor panel of the corresponding hall.

(ST7) At this time, the card identification code stored in the previous step ST5 is added to the display code. The sensor panel transmits the display code and card identification value input by the elevator control unit 30 as a radio signal (Sr1). The mobile card 1 receives a radio signal (STIO). Then, the mobile card 1 compares the received radio wave signal, that is, the card identification code included in the received signal, with its own card identification code (S Tll, 12). As a result of the verification, if there is a discrepancy, it is determined that the mobile card 1 is not sending information addressed to itself,
Wait for reception again (return to STIO). If they match, the mobile card 1 determines that the transmitted information is addressed to itself, and outputs the display code input together with the card identification code as an image to the display 5 provided on the mobile card 1 (
ST13), the elevator user looks at the identification value of the service elevator shown in the display content and waits in front of that elevator (ST14).

〔Effect of the invention〕

As detailed above, according to the present invention, a user can register a hall call simply by inputting the floor to be used using a mobile card, thereby selecting and specifying a service elevator for that user. By looking at the elevator number information displayed on the display section of the mobile card, the user will be able to know which elevator to use.

Since the group management means specifies service elevators for each user based on floor instructions for each mobile card, even if the assigned elevator is changed during busy times, there will be no backlogs or customers will not be concentrated in a specific elevator. It is possible to average the amount of data and improve the service.
