Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved device for displaying elevator waiting times at a landing.

In the group control elevator, when a hall call is registered, a car is assigned to it and the assigned car is operated so as to respond to the hall call. The predicted waiting time from when the hall call is registered until the assigned car arrives at the hall is displayed at the hall for the convenience of waiting passengers. Furthermore, it is proposed that this predicted waiting time be updated at appropriate time intervals.

However, it is difficult to accurately predict waiting times (in order to improve the accuracy of predicted waiting time display, it is necessary to detect the number of waiting passengers at each landing, the destination floor of the waiting passengers, etc.), which is complicated and difficult. (requires expensive equipment to be installed). For this reason, the accuracy of the predicted waiting time as described above is not necessarily good, and since it is not known whether the waiting time display is actually correct or incorrect, it tends to exacerbate the sense of distrust among waiting customers.

This invention is intended to improve the above-mentioned problems, and aims to provide an elevator waiting time display device that can prevent waiting customers from feeling impatient, distrustful, etc. even if the predicted waiting time is not accurate. .

Hereinafter, an embodiment in which the present invention is applied to an up-call at a landing on the fifth floor will be described with reference to FIGS. 1 to 4.

1b is the first floor car call registered in Unit 2, 4b
is the 4th floor assigned landing call that has already been assigned to Unit 2, and 5u is the 5th floor that has not yet been assigned.
This is a call to go up to the landing on the floor.

In Figure 2, 8A and 8B are the landing areas for Cars 1 and 2 on the 5th floor, 9 is the landing button, 10A, 1
0B is the uplight of the arrival forecast light of Unit 1 and Unit 2, respectively, 11A and 11B are the downlight, and 12
Similarly, A and 12B are waiting time indicators.

In Figure 3, 13A and 13B are stop count signals corresponding to the stop times of Unit 1 and Unit 2, respectively;
4A and 14B are car position signals indicating the car position (floor), 15A and 15B are driving direction signals indicating the driving direction of the car, and 16A and 16B are signals for the assigned car after the 5th floor landing up call is registered. This is a circuit that calculates the predicted waiting time until the arrival of
It is a publicly known thing. 17 is an allocation circuit that allocates a car to a call up to the landing on the 5th floor, 17a and 17b are the outputs thereof, and selection signals for car No. 1 and car No. 2, and 18A and 18B are the outputs that indicate the contents at that time when terminal T becomes "H". Holding circuit held, 19A, 1
9B is the R-S flip-flop (hereinafter referred to as memory), 19Aa and 19Ba are the outputs of memories 19A and 19B, and the up call signal for the assigned hall on the 5th floor, 20A,
20B is a stop decision signal that becomes "H" when the No. 1 and No. 2 cars decide to stop, respectively; 21 is a hall call continuation time counting circuit that counts the elapsed time since the 5th floor landing up call is registered; 22 25 are gate circuits that output an input when the terminal T becomes "H", and 26 and 27 are gate circuits that output either of the two inputs.

Next, the operation of this embodiment will be explained.

Now, as shown in Figure 1, it is assumed that Car 1 is about to depart from 1 on the 1st floor in order to respond to the up call 2a of the assigned landing on the 2nd floor and the car call 3a on the 3rd floor, and that Car 2 is on the assigned landing on the 4th floor. It is assumed that the user is about to depart from the sixth floor 6 in order to respond to the down call 4b and the car call 1b on the first floor. At this time, it is assumed that an inbound call 5u from the landing on the 5th floor is registered.

The predicted waiting time calculation circuits 16A and 16B output the 5th floor up call signal 5u and the stop count signals 13A and 13.
B, the predicted waiting time is calculated from the car position signals 14A, 14B and the driving direction signals 15A, 15B.

Here, the time required to travel on the first floor is 2 seconds, 1
Time required to stop (from stop to departure) 10
As seconds, it is calculated as follows.

2N _f +10N _S Here, N _f1 : Number of floors the car travels from its current position to the 5th floor N _S : Scheduled number of stops from the car's current position to the 5th floor Therefore, Unit 1 The predicted waiting time for is 2×4+
10 x 2 = 28 seconds, the predicted waiting time for Unit 2 is 2 x 9 + 10
It is calculated as ×2=38 seconds. The allocation circuit 17 compares the predicted waiting times and selects the car with the shorter wait time. In this case, it is clear that the No. 1 car is selected, and the selection signal 17a becomes "H". The memory 19A is now set, and the holding circuit 18 holds the contents corresponding to the predicted waiting time at that point, that is, 28 seconds. Further, as is well known, the uplink light 10A of the arrival forecast light is turned on as an assigned light. On the other hand, since the output of the memory 19A has become "H", the gate circuit 22 is closed and the gate circuit 23 is opened. Therefore, the content of the holding circuit 18A is the same as that of the gate circuit 2.
3, 26, waiting time display 12A
``28 seconds'' is displayed as shown in Figure 4A.
As the memory 19A is set, the 5th floor assigned hall inbound call signal 19Aa becomes "H", so the well-known group control circuit selects car No. 1 as the assigned car and responds to the 5th floor inbound call 5u.

On the other hand, in the hall call duration counting circuit 21, 5
The elapsed time since the up-floor call signal was issued is counted every moment. Since the No. 1 car stops on the 5th floor 5, when the stop decision signal 20A becomes "H", the memory 19A is reset and its output 19Aa becomes "L". With this, the gate circuit 23 is closed and the gate circuit 22 is opened, so "28 seconds" on the waiting time display 12A goes out, and instead, the content of the counting circuit 21 (assuming 30 seconds) is displayed on the gate circuit 22. ，
26, and the waiting time display 12A displays "30 seconds" as shown in FIG. 4B. In addition,
When the first car arrives at the fifth floor, the up call signal 5u becomes "L", but the counting circuit 21 continues to output for a predetermined period of time. Further, the uplight 10A of the arrival forecast light blinks to notify the arrival of the car.

In this way, when a hall call is registered and a car is assigned, the predicted waiting time for that hall is displayed, and when the car arrives, the actual waiting time is displayed, so the accuracy of the predicted waiting time can be estimated by analogy. be able to. At the same time, it is also possible to estimate the accuracy of the predicted allocation calculation. In addition, the waiting customers can enjoy predicting whether the prediction is correct or incorrect, which helps relieve the feeling of frustration while waiting for the car to arrive.

FIGS. 5 and 6 show other embodiments of the invention.

In the figure, 18Aa and 18Ba are holding circuits 1 and 18Ba, respectively.
The outputs of 8A and 18B are predicted waiting time signals at the time of allocation for the first and second cars. 21a is the output of the hall call duration time counting circuit 21 and is a hall call duration signal. 3
0 is a gate circuit similar to gate circuit 26, and 31 is an output of "H" when the input of terminal X>the input of terminal Y.
, a comparator whose output is "L" at all other times, 32 is a monostable element that emits a pulse signal with a constant time width when the input becomes "H", and 33 indicates the elapsed time while the input is "H". This is a clock signal generation circuit that counts and generates a clock signal in seconds, and when the input goes to "L", the clock signal is held at that time.When the input to terminal R goes to "H", the contents are reset and the uplink call is started at that time. A clock signal generation circuit that starts re-counting when the signal 5u becomes "H"; 34 and 35 are gate circuits similar to the gate circuits 23 and 25; 36;
A and 36B are hall call continuation time display devices installed in parallel with the waiting time display devices 12A and 12B of the first and second cars, respectively. Note that the holding circuits 18A, 18
R of B is a reset terminal, and when its input becomes "H", the contents are reset. Others are the same as in FIG. 3.

Now, in the same manner as in the embodiment shown in FIG.
Aa is "H"), and at the same time that the uplight 10A of the 5th floor landing turns on, "28 seconds" is displayed on the waiting time display 12A.

Now, the gate circuit 34 is opened, so the clock signal from the clock signal generation circuit 33 is transmitted to the gate circuit 34.
4 to the hall call duration indicator 36A, and as shown in FIG. 6A, "1", "2",
The time is displayed in 1 second increments such as "3"... On the other hand, in the comparator 31, the hall call duration signal 21
a and the predicted waiting time signal 18 through the gate circuit 30.
Aa is compared, and if the former is longer than the latter, that is, if the actual waiting time exceeds 28 seconds, the output of the comparator 31 becomes "H". Now, the monostable element 32 emits a pulse signal, and the clock signal generation circuit 33
is reset, the hall call duration display 36A again displays the times as "1", "2", "3", etc., as shown in FIG. 6B. On the other hand, since the holding circuit 18A is reset by the pulse signal of the monostable element 32, the predicted waiting time at that point (the 1st car is approaching the 5th floor) is held again, and is output through the gate circuits 23 and 26. be done. As a result, the predicted waiting time held again (in this case, 2 seconds) is displayed on the waiting time display 12A, as shown in FIG. 6B. When the first unit arrives, the uplight 10A starts blinking and the display 1
2A and 36A respectively display "2 seconds" as shown in FIG. 6C.

Since the clock is displayed in this way, it is easy to recognize whether the prediction is successful or not. In addition, since it displays how long to wait after the prediction is incorrect, it is useful for eliminating distrust among waiting customers.

Note that the same explanation can be given for the case of the second car, the case of a down-hall call, and the case of a different floor.

As explained above, in this invention, when a hall call is registered, the predicted waiting time until the assigned car arrives at the hall is displayed, and when the assigned car arrives at the hall, the actual time of continuation of the hall call is displayed. This makes it possible for waiting customers to enjoy predictions that are hit or miss, and eliminates the feeling of frustration until the car arrives.

In addition, the predicted waiting time and hall call duration are displayed, and when the hall call duration becomes longer than the predicted waiting time, the predicted waiting time at that point is redisplayed, and the hall call continues from that point. Since the time is redisplayed, customers can easily recognize when the prediction is a hit or miss. It is also possible to know the waiting time after the prediction is incorrect.
