Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for displaying predicted elevator waiting time.

When a hall call is registered, the group control elevator calculates the time for each car from the current moment until it responds to the hall call (hereinafter referred to as predicted waiting time), and based on the calculation result, assigns the car to the hall call. I am trying to assign it to For example, Japanese Patent Laid-Open No. 56-523'74 discloses a system that displays a predicted waiting time that changes from moment to moment at a landing. The following two types of display methods are available for displaying changes in the predicted waiting time over time by cumulatively decrementing them every second.

Display The calculation result of the predicted waiting time at that time is displayed every 15 seconds.

Display 2 After the predicted waiting time is displayed for the first time, the elapsed time is subtracted from the first predicted waiting time and displayed thereafter, regardless of the calculation result. If the predicted waiting time reaches 0 seconds and the car has not yet arrived, the predicted waiting time at that point is displayed again.0 This can be specifically expressed numerically as follows.

It is assumed that the calculated predicted waiting time at the time of car allocation (the time of hall call registration) is 20 seconds. On both display 1 and display 2, the arrival forecast light lights up, 20 seconds is displayed, and 20.1
9.18... is displayed as a cumulative decrease every second. However, it is assumed that the traffic arrives after 5 seconds have elapsed (and that the vehicle will finally arrive in 25 seconds). At this time, in Display 1, the cumulative decrease was displayed at the age of 16 seconds, but it will be displayed again from 25 seconds. In display 2, the display is not changed at that time, 15, 14.13...
When the display reaches 0, it will be displayed again from 10 seconds, which is the calculation predicted waiting time.

In this way, the predicted waiting time is displayed on the front claw,
Displays must be changed depending on changes in traffic conditions. In this case, the predicted waiting time, which is intended to prevent waiting customers from feeling impatient, may actually have the opposite effect.

This invention improves the above-mentioned problem. By displaying the predicted waiting time after a predetermined interval has elapsed after the car is allocated, there is less possibility of the display changing due to changes in traffic conditions, and the accuracy is improved. It is an object of the present invention to provide an elevator waiting time indicator γ1 capable of performing the above in Table 7J.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. However, the figure shows the first floor.

In Figure 1, (la) and (lb) are the landing doors of Units 1 and 2, (2a) and (2b) are the landing doors (la), (
lb) uplight of the arrival forecast light installed on the upper wall, (

5) is a landing button installed on the wall between landing doors (la) and (lb).

In Fig. 2, (6) is a means for calculating the predicted waiting time, which is the landing button (5) and the elevators ('7a) of No. 1 and No. 2 cars.

Based on the signal from (7b), the predicted waiting time for the floor where the landing button (5) was pressed is calculated, and a car is assigned based on this. When a car is assigned, the corresponding arrival warning lights (2a), (2b), (3a), (3b)
lights up. (8) is a delay means that outputs an output when the estimated waiting time at the time of car allocation has elapsed, and displays the waiting time display (4).
a) Display the predicted waiting time at that point in (ab).

In FIG. 3, (10) is a group management device composed of a microcomputer, which includes a central processing unit 91 (IOA) and a read/write memory (R) for storing data such as operation results.
OM) (Converter (1
0D) to (IOF).

Next, the operation of this embodiment will be explained using FIG. 4.

Note that this program is repeatedly executed.

11t, i+21+ reads the signals of the landing buttons (5) on each floor and determines which hall calls are not marked.
Using the signals from 7a) and ('7b), the predicted waiting time for the corresponding power 1 is calculated for each car in step (22) according to a known procedure. A hall call is assigned to the predicted waiting time calculated in step (23), which is an appropriate value (for example, the minimum value) of /12. Step (241) The predicted waiting time at the time of allocation is stored in R, AM (IOB). Step (25)
Determine whether % of the predicted waiting time at the time of the above allocation has elapsed, and if it has not elapsed (-r (t), vY ends. 'If A has elapsed, move 11.((219 Then, the calculated predicted waiting time is displayed on the conversion device 7.

Next, if it is determined in step (21) that all visitors have been assigned 1+;-, it is determined in step ㅅη whether there are any hall calls that have been assigned, and if those hall calls have been answered. If it has been released, the process ends. If no response has been received yet, the predicted waiting time for that hall call is calculated in step (28). That is, steps (27) and (28) are steps for calculating changes in predicted waiting time after allocation.Thereafter, steps (251 and (26)) are similarly performed, and changes in predicted waiting time are displayed.

Assuming that the predicted calculation time at the time of car allocation is 20 seconds, a concrete example of the predicted waiting time display is as follows.

In other words, the predicted waiting time is not displayed when the landing button (5) is pressed, but the predicted waiting time calculated at the time of car assignment is 20.
This is displayed after 10 seconds (% of seconds) have elapsed. Once this is done, the predicted waiting time at that point is highly accurate, and there is little ljJ possibility of changing it thereafter. 1, when the visitor button (5) is pressed, the inbound phantom (2a) of Unit 1 lights up to guide the waiting customers, as mentioned above, and after that, when the waiting customers start to feel impatient, the waiting time starts. 11JI By displaying information on the display device (4a), it is possible to draw the attention of waiting customers to that direction.

In the embodiment, the predicted waiting time is displayed at the time when % of the predicted waiting time at the time of car allocation has elapsed, but it may be set to a certain period of time (for example, around 10 seconds) from the time of car allocation. It's 1.
It is also possible to change the response time depending on traffic conditions by changing it to around 5 to 20 seconds or when the average non-response time has been exceeded.

As explained above, in this invention, when an elevator hall call is registered, the predicted waiting time is calculated for each car, the car is assigned, and the forecast is displayed at the hall. By displaying the predicted waiting time at the point in time, it is possible to calm down the frustration of waiting customers when they start to feel anxious, and also to provide a highly accurate predicted waiting time with less possibility of subsequent epicenters. Can be displayed.
