Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an elevator system, and is particularly directed to an elevator system that services multiple floors. This invention relates to an elevator system that displays a staircase usage display that indicates a floor range that is more advantageous, and improves service to hall passengers.

[Technical background of the invention and its problems] In an elevator system that services multiple floors, usually 1
In elevator equipment that is serviced by one or two cars, such as a car-controlled elevator or a two-car control elevator, there is a hall indicator that displays the current car position in each hall, and the hall owner can be roughly estimated. can obtain information about waiting times.

On the other hand, in a group management control elevator system that selectively allocates and controls common hall calls to three or more elevators, overall operational efficiency is taken into account for each hall call that occurs. In order to control the car to provide the best possible service operation, passing through floors and reversing the car may occur depending on the situation.Therefore, there is usually no hall indicator in each hall to display the position of each car, but there are hall lanterns,
Chimes are used to guide passengers.

However, with only the above hall lanterns and chimes, customers waiting in the hall have no information about the waiting time, such as how many seconds it will take for the elevator to arrive.

Therefore, if the customers waiting in the hall are in a hurry or
When traveling between a small number of floors (about 4 floors), it has been impossible to judge whether or not it is better to use an elevator.

Therefore, as a countermeasure, there is a system that displays waiting time information in each hall, such as how many seconds it will take for the elevator to arrive, but it is difficult to predict the displayed data itself.
Lack of accuracy in data can lead to incorrect predictions and even have the opposite effect. In addition, even in elevator equipment equipped with hall indicators that display the position of each car (1 car, 2 car, etc.) as described above, there is information that the car stops at an intermediate floor between the current car position and the customer's destination floor. Because there is no information on waiting time, it is only possible to predict data that contains a considerable amount of error. Therefore, customers waiting in the hall call the hall, wait for a while, and when the car does not arrive, they use the stairs instead of using the elevator.
As a result, elevator operation efficiency deteriorates in response to unmanned halls, and in order to improve efficiency, it is necessary to prevent unnecessary hall calls from occurring.

OBJECT OF THE INVENTION] The present invention has been made in view of the above circumstances, and its purpose is to provide an elevator system that services multiple floors, regardless of whether or not there is a hall call. Based on the predicted arrival time of the elevator arriving at the hall and the predicted time to use the stairs if walking, it is determined which floor range it is faster to use the stairs than to wait for the elevator, and this information is displayed in each corresponding hall. By providing information on waiting times to hall customers,
To provide an elevator device capable of suppressing the generation of unnecessary hall calls, reducing traffic between floors of users of approximately 2.3111 floors, and improving operating efficiency of the elevator.

[Summary of the Invention] That is, in order to achieve the above object, the present invention provides means for calculating a predicted arrival time to each hall in an elevator system serving multiple floors, and means for calculating a predicted arrival time to a predetermined hall based on the above calculation data. Means for determining a floor range in which it is more advantageous to use the stairs based on a comparative judgment with the staircase usage time when the user uses the stairs, and generating stairs use floor information indicating the floor range; It is equipped with a display means for displaying this information and guiding hall passengers, and calculates the predicted arrival time to each hall, and based on this calculation data, calculates the estimated arrival time for a given hall if the user uses the stairs. By generating floor information indicating whether it is better to use the stairs or the elevator based on comparison judgment with time and guiding hall passengers, it is possible to get to the destination floor before making a hall call. To make it possible to judge whether it is better to use an elevator or not, thereby preventing unnecessary hall calls.

More specifically, each predicted arrival time from a desired floor to another floor is calculated based on the current car position of each car, car call information, and hall call information, and the answering car number is calculated regardless of whether there is a hall call. Based on the above data and the stair usage time data for each floor after considering the stair layout of each hall, determine the maximum number of floors for which it is faster for users to use the stairs. Display it in the corresponding hole.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a basic system to which an embodiment of the present invention is applied. Here, a group control elevator system that controls three elevators will be explained as an example.

As shown in the figure, the group management elevator system employs a method in which an optimal elevator is selected from among a plurality of individual elevators A, -C to respond to a hall call made by a common hall call button 5.

The group management control device 1 is connected to individual control fl devices 2a, .about.2C that control each individual elevator, and receives 1q of information regarding each car from each individual control device 2a, .about.2C. Further, the group management control device 1 gives commands to respond to hall calls, etc. to the individual control devices 2a, -2C.

The group management control device 1 is also connected to a display device 4 according to the present invention for each hall, and controls the display contents in real time based on information about each hall call of each car.

FIG. 2(a) is a diagram showing the interface between the display device 4 and the group management control device 1 and the display circuit according to the present invention, and shows the output sofa-BF1. It is composed of a driver Dv that generates a drive output based on the output of this output buffer BFI, and a light emitting display element LD such as an LED that emits light based on the output of this driver DV.

As shown in FIG. 1, it is connected to the computer of the group management control device 1, and is configured to be directly driven by the group management control device. As shown in FIG. 2(b), the display form is composed of a 7-segment LED light emitting display element LD in which the segments LO and L6 are formed in a sun-shape. It takes the form of displaying numbers.

FIGS. 3 and 4 show specific display forms in the hall of the display device 4 according to the present invention.

The display device 4 is installed for each hall call (LIP and DOWN), and the 7 segment portion is directly controlled in real time by the group management control device 1 using the configuration shown in FIG. 2, regardless of the presence or absence of a hall call. , with a structure in which the numbers change.

In addition, DR is the elevator door, 5 is the hall call button, HL
is a hall lantern.

Next, the control operation of the display device will be explained with reference to FIGS. 5 and 6.

5(a) and 5(b) are flowcharts of tasks in display control of the computer of the group management control device 1. Also,
FIG. 6 is a table of the walking time required for each floor when using stairs, which is determined based on the layout of halls and stairs for each building, and is written in the ROM data area in the computer. In this example, the time required to walk the first floor is 1
8 seconds.

The time required to walk the second floor is 26 seconds.

The operation of this device will be explained with reference to the flowchart in FIG. The display control task is performed by the computer of the group management control device 1 executing the flowchart shown in FIG.

First, every time this display control routine is entered, the computer executes step St1. Step st2 is executed, and it is determined for each floor H whether or not there is a hall call allocation machine on the hall call floor (H).

That is, the presence or absence of hall call allocation is determined for each hall call. This is a process to determine the target car to be displayed. Next, if the allocation is in the status, the assignment is @machine, and if there is no hall call, and if the allocation is in the status, the hall call is for that floor. is temporarily generated, and the responding machine is determined using a predetermined selection algorithm (step st3 to step 5t4). Next, the evening decided above~
The expected arrival time of the target floor is calculated for the target responding car (step 5t5). Then, based on the expected arrival time, it is compared with the data in the stair usage time table shown in Figure 6, and the maximum floor difference where the stair usage data is smaller is determined using the floor difference index I (step st6). .~Step 5t8). This value currently indicates the floor where it is faster to reach the destination floor by using the stairs than by using the elevator.

Then, the floor difference index value determined for each hall is converted into a code for 7-segment display, and output to the hall (step 5t9). This task is activated on the group management control device 1 at intervals of about 1 second,
Display control is performed in real time.

As a result, the light-emitting display element LD of the display device 4 emits light to indicate the number of floors corresponding to the maximum floor difference where the stair usage data is smaller for each target floor. At this point, it is easier to walk to the floor than to wait for the elevator. Therefore, users will be able to immediately decide whether or not to use the elevator by looking at this information display, reducing unnecessary elevator hold times and unnecessary hall calls, improving customer service and improving elevator service. can improve the operational efficiency of

The above was explained in the group control elevator system, but 1.
It is clear that similar implementations can be made in car and two-car elevator systems. Further, in this embodiment, a display device is installed and displayed for hall calls on all floors, but the same implementation can be performed by installing only on a reference floor or a specific floor where there is inter-floor traffic. Furthermore, although the configuration is such that the display is always displayed during the time period, it is also possible to display the display only during the time period when demand is high. Further, although a light emitting element such as an LED is used as a display element, the present invention is not limited to this. In addition, in this embodiment, the display is displayed regardless of the presence or absence of a hall call, but if there is a system that installs a hall call cancellation button, the display may be canceled after a customer waiting in the hall registers a hall call by mistake. Changes can be canceled if the changes are made, making them more effective in improving operational efficiency. In addition, in this embodiment, for floors where no hall call is registered, the responding car is determined as the target car by a predetermined evaluation, and if the hall call is registered, the allocation is determined to be the target car. However, it can be handled in the same way when displaying the target aircraft as the minimum arrival time aircraft.

It is clear that the above case can be made possible by changing the response car determination process in the flowchart of FIG. 5 <a> to the minimum arrival time car condition.

[Effects of the Invention] As detailed above, according to the present invention, in an elevator system that services multiple floors, the predicted arrival time of the answering car for each hall and the expected arrival time of the answering car when the user uses the stairs to reach each floor are calculated. By comparing the time required to use the stairs, control is performed in real time regardless of whether there is a hall call, and the range of floors where it is more advantageous to use the stairs is displayed in the hall, thereby reducing the time required for each hall. In addition, it is possible to provide correct guidance to customers waiting in a hurry and those using the second and third floors, reducing overall demand in buildings with standard floors and inter-floor traffic. In addition, it is possible to provide an elevator apparatus having features such as being able to suppress the generation of unnecessary hall calls and improve the operating efficiency of the elevator.
