Abstract

PURPOSE:To allow users to estimate necessary waiting times, by giving the users previous guide immediately when an estimated arrival time is short, and giving them the guide after passing over a pre-determined time when it is longer. CONSTITUTION:When a hall button HB is pressed for calling an elevator, a group-control unit 1 calculates estimated arrival times for respective elevators to arrive to the hall so as to propose an elevator which has the shortest estimated arrival time as its candidate service elevator. An elevator number controller 2 compares the estimated arrival time with the first pre-determined time, and when the estimated arrival time is shorter than the first pre-determined time, it determines the candidate elevator as a service elevator and gives previous guide immediately by means of a service lamp 4 on the floor and a hall information 5. When the estimated time is longer than the first pre-determined time, the controller, reserves the previous guide, checks the candidate one by one and, after the second pre-determined time passes over it determines a service elevator to give the previous guide. Thus it is possible for users to wait with ease for a service elevator.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a service elevator reservation guidance system and apparatus suitable for making service reservations for group-managed elevators.

[Conventional technology]

Many proposals have been proposed in the past regarding instant reservation guide systems for instantly reserving service elevators.

For example, in Japanese Patent Application Laid-open No. 49-945, if the elevator is far from the hall call by more than a predetermined distance, reservation guidance is suspended, and in Japanese Patent Application Laid-Open No. 52-86650, the position of another elevator is Furthermore, it is possible to make a reservation when the load in the car satisfies a predetermined condition, as disclosed in Japanese Patent Laid-Open No. 53-2.
No. 850 discusses calculating a reservation loss rate and notifying the reservation when a predetermined condition is met.

The instant reservation information method is popular with users because they can immediately identify the service elevator and simply wait in front of the elevator for which the reservation was made.However, if traffic demand exceeds the elevator installation capacity, In cases such as when a car call that is significantly different from the prediction occurs after making an instant reservation,
If the service elevator is left unchanged, the service elevator will become full or the elevator will last a long time, forcing the user to change the reservation to change the service elevator, resulting in a betrayal of the users.

Therefore, in order to reduce the occurrence of the above-mentioned reservation changes, Japanese Patent Laid-Open No. 53-36854 proposes a long-term reservation hold system. This long-waiting reservation hold method is
After hall call registration, if the estimated arrival time until the elevator arrives at the hall is less than a predetermined value, the reservation will be made immediately; however, if the estimated arrival time exceeds the predetermined value, the reservation will be put on hold and the estimated arrival time will be This is a system in which reservation information is provided when the time period decreases to a predetermined value (for example, 45 seconds) or less.

[Problem to be solved by the invention]

However, in the conventional reservation hold method for long waiting times,
The reservation hold time is not fixed, and users do not know how long they will have to wait. Moreover, when the reservation hold time becomes quite long, there is a problem in that the user has to wait impatiently.

Note that there is also known a reservation holding system at the time of registration, in which the reservation is announced after a predetermined period of time (for example, 10 seconds) has elapsed after hall call registration, regardless of the predicted arrival time. However, with this method, if the predicted arrival time is short, the service elevator will arrive at the relevant hall quickly, making it difficult for users (especially elderly people and people with baggage) to have enough time to move to the service elevator. There is a problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator reservation guidance system that optimally guides the reservation of a service elevator so as to minimize the degree of irritation until the arrival of the service elevator.

[Means to solve the problem]

In order to achieve the above object, the feature of the service elevator reservation guidance system of the present invention is that when determining a service elevator for a hall call from among a group of managed elevators, the service elevator is If the predicted arrival time is less than the first predetermined time that increases the frequency of occurrence of problems such as reservation changes, reservation information will be provided immediately after hall call registration, and the predicted arrival time will be changed to the first predetermined time.
If the predetermined time is exceeded, the reservation information is delayed by a second predetermined time after hall call registration to ensure a more reliable service elevator.

Furthermore, the present invention is such that the above method is implemented on a specific floor, during a specific time period, and during a specific traffic flow.

Furthermore, the service elevator reservation guidance device of the present invention includes:
A calculation means that calculates the predicted arrival time until the service elevator is serviced in the hall, and compares the predicted arrival time with a first predetermined time that increases the frequency of failures such as reservation changes, and calculates the predicted arrival time. If it is less than the first predetermined time.

A control means for providing immediate reservation guidance for a service elevator and, if the predicted arrival time exceeds a first predetermined time, for reserving a service elevator with a delay of a second predetermined time in order to review a more reliable service elevator. .

[Effect]

According to the above configuration, when a hall call occurs, the calculation means calculates the predicted arrival time for each elevator to arrive at the hall, and selects the elevator with the shortest predicted arrival time as a candidate for the service elevator. Then, the control means compares the predicted arrival time and the first predetermined time, and determines that the arrival time is the first predetermined time.
If the time is shorter than the predetermined time, the above-mentioned candidate elevator is determined as a service elevator, and reservation guidance is given to the hall of the hall call. In addition, if the arrival time is longer than the first predetermined time, the reservation information is put on hold, service elevator candidates are sequentially considered, and the service elevator is determined and the reservation information is determined after a second predetermined time has elapsed from the generation of the hall call. .

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings while comparing it with a conventional example.

First, the names of the main symbols used in the following explanation and their meanings are shown in Table 1 at the end of Volume 1.

FIG. 1 shows an overview of the group control elevator system. In this figure, when the hall button HB is pressed, the group management control unit W1 determines the service elevator according to a predetermined rule (for example, a rule that assigns the elevator with the minimum predicted arrival time to the corresponding hall call of each elevator). , the heel 3 of the service elevator is driven via the control device 2 of each car, and the service reservation light 4 is turned on. Furthermore, this elevator system is provided with a hall information 5 for displaying general information and a user command board 10.

Fig. 2 is a view of the hall from directly above, and after the waiting customer P presses the hall button HB at position A, the service reservation light 4 lights up and the waiting customer P moves from position A to B. T to position
This means that it takes R time to move.

The waiting time distribution in a hall usually exhibits a curve characteristic as shown in FIG. 3, and the occurrence ratio gradually decreases as the waiting time becomes longer.

As the predicted arrival time becomes longer, as shown in FIG. 4, the rate of reservation changes (change of service elevator due to fullness, long waiting time, etc.) increases. Since elevator equipment is limited, the reservation change rate cannot be reduced to zero unless extremely long waiting times are tolerated. In order to increase the utilization rate of the building, the area occupied by elevators is kept to a minimum, so long expected arrival times occur to some extent.

If the predicted arrival time is 180 or more, if the reservation is put on hold without immediate reservation guidance, and the reservation guidance is only given when the predicted arrival time is less than or equal to T z c, it can be said that there will be almost no reservation changes.

An example of such a method is the long-duration reservation hold method shown in the time chart of FIG. . In this method, the reservation holding time T
A problem arises when the reservation holding time T)l becomes considerably long due to variations in H=T^-e, during which the user becomes impatient and waits.

Further, in the case of FIG. 6(b), the reservation is held at the time of registration in which the reservation is held for TH without immediate reservation guidance.

Although this method has the disadvantage that it does not allow immediate reservations, it is convenient for users because they will always be notified of a reservation if they wait a certain amount of time. However, if the lighting time T^-TH of the service reservation light is shorter than the waiting customer preparation time TR as shown in FIG.

A time chart of the elevator reservation guidance system of the present invention is shown in FIG. 6. In the system of the present invention, as shown in FIG.
If the predicted arrival time T^ is less than or equal to the first predetermined time T,
Provide immediate reservation information and immediately turn on the service reservation light. Also, as shown in the same figure (b), the predicted arrival time T^ is the first
If the predetermined time T1 is exceeded, the reservation is suspended for a second predetermined time T2 without providing immediate reservation guidance.

With this type of system, if you receive immediate reservation information, you will have a rough idea that the waiting time will be less than the first predetermined time T2, and if you wait for a predetermined time (second predetermined time T2), you will definitely be notified of your reservation and will not have to wait. It is possible to obtain an indication that the time is longer than the first predetermined time T. Therefore, the user can wait with satisfaction.

A flowchart of the present invention is shown in FIG. Although the case of the hall call is shown here, the same processing is available for other calls as well. In the figure, when a hall call occurs, the main process starts with an interrupt from step BO5,
In step B10, the reservation pending counter t is cleared. Then, in step B15, service elevator candidates for the hall call are selected from the latest predicted arrival time table T1.
Determine using 0. Furthermore, in step B20,
The predicted arrival time TAK of the candidate aircraft is compared with the first predetermined time T in the table T20, and if the predicted arrival time T^≦first predetermined time T□, proceed to step B40;
The service reservation light is turned on to provide immediate reservation information. Further, in step B20, if the predicted arrival time T^ is > the first predetermined time T, the process proceeds to step B25, where the reservation hold counter t is compared with the second predetermined time T2 in the table T30. Then, in step B25 and step B30, the service elevator candidates are reviewed in step B35 while counting up until the reservation hold counter t exceeds the second predetermined time T2.

In step B25, if the reservation hold counter t>second predetermined time T2, the process advances to step B40, where the service reservation light is turned on and the service elevator is reserved.
According to the above flow, the process in step 835 makes it possible to review the most suitable elevator until just before the service reservation light turns on.

FIG. 4 shows a method for determining the first predetermined time T with the reservation change rate as a target. The target curve GRH in FIG. 1 is created from table T95 (see FIG. 9), which will be described later. In the figure, initially, a first predetermined time T 1 a is set from the target curve GRH for the reservation change rate target M&,
At this point, we would decide whether to make an immediate reservation or put it on hold. However, if a request to lower the reservation change rate 1 occurs, the target is changed from Ma to Mb, and the corresponding T4. , is set as a new first predetermined time, and the lighting control of the service reservation light is performed. The reservation change rate can be changed in this way by operating the user command board 10 shown in FIG.

FIG. 8 shows a method of determining the first predetermined time from among two targets for the reservation change rate and the full pass rate using the user command board 10.

In the figure, a user command board 10 is provided with a selection key 10A, an execution key 10B, and a cursor key 10C, and can be operated using these keys in conjunction with the screen. The target curvature GRH1 for the reservation change rate is shown by a solid line, and the target curvature GRH for the full capacity passage rate is shown by a broken line.

The target for the reservation change rate is My, and the target for the full pass rate is MM.
If so, the target curve GRH□, GRH.

The first predetermined times corresponding to Tly and T□H are respectively Tly and T□H
Then, the smaller one of them, TlY, is adopted as the first predetermined time, and the process shown in FIG. 7 is executed. According to this method, it is possible to realize an elevator reservation guidance system that satisfies multiple goals.

As a result, if the target value M is changed in various ways according to fluctuations in the usage status of the building or customer preferences, it becomes possible to newly set the corresponding first predetermined time T□. Also,
When there are many targets, the target curve GRH can be made steeper or gentler by inputting human sensitivity to compare the importance levels among the targets. As a result, compared to determining the first predetermined time T□ from mere measured data, control that fully reflects the individuality of the customer becomes possible.

The first predetermined time Ti can be determined in the same manner as described above even in the case of a long waiting rate or an average waiting time in addition to the reservation change rate and full capacity rate.

FIG. 9 shows an example of a learning data table for creating the target curve GRH. In order to improve the reliability of the − layer target curve, table T95 is configured to learn each traffic flow, such as traffic flow at the time of work. For each hall call that occurs, we record where it belongs in the expected arrival time period (in 10 second increments), and also count whether the reservation has been changed or not and whether the hall is full or not.
You can obtain target curves for reservation change rate and full capacity passing rate.

The target curve is refreshed by performing exponential smoothing on the previous values. Also, the reliability of the target curve is increased by performing least squares approximation of the plot points. In this way, highly accurate control can be expected because data is collected for each traffic flow mode.

10 and 11 show a case where there is a hall information 5, and this hall information 5 also serves as a service reservation light 4. If there is no hall call, the hall information 5 of all machines is turned off. When the predicted arrival time T^≦first predetermined time T, immediate reservation information is provided, and the service reservation light 4 is turned on only in the service elevator as shown in FIG. Here, waiting time (triangle contents), car position @ (4), car direction (
@), door opening/closing status, and display examples of passengers getting off are shown. Figure 10 shows the predicted arrival time T^〉 when the call is registered.
In the case of the first predetermined time T, since the service elevator has not been determined, all the lights are turned off and a general message is played on the display of all the cars that do not have reservation information, so that the call of the waiting customer is answered. It is possible to show that the customer has waited for a long time and to reduce the feeling of waiting for a long time. Second predetermined time T2
When the service elevator is confirmed after the reservation has been put on hold, the display as shown in FIG. 11 will appear. By doing so, it is possible to perform a display suitable for the waiting time.

FIG. 12 shows the relationship between the reservation change rate and the degree of irritation upon arrival for cases where the predicted arrival time is short and long.

When the predicted arrival time T^ is short, as the predicted arrival time T^ increases, as the predicted arrival time T^ increases, the reservation change rate Y decreases and the irritability level increases.

In addition, when the predicted arrival time T^ is long, as shown in (b) of the same figure, as the predicted arrival time T^ increases, the reservation change rate Y and the irritation level I will be the same as in (a) of the same figure. However, irritability can be divided into four cases. In other words, (1) in the figure shows the case where the reservation is held until the end, (2) shows the case where the reservation is held until T)l and then the reservation is announced, (3) shows the case where the reservation is made immediately, and (4) shows the case where the reservation is made immediately. The cases in which general information was leaked are shown below. Among these, when comparing (1) to (3) above, the following relational expression holds true when the degree of discomfort of waiting customers is f (Y, I).

f(Ys, Is) > f(Yo, In) < f(0
, Iz) (immediate guidance) (reservation hold) (arrival guidance only) Therefore, for the reservation hold time TH, min
The TH of f (Y, I) TH is adopted as the optimal reservation holding time.

FIG. 13 shows an example in which the degree of importance (personality of the customer) is input from the user command board 10 by comparing the reservation change rate and the degree of irritation. As shown in figure (a),
You can change the degree of importance by moving the Δ mark left or right using the cursor keys.

The optimal reservation hold time TH that gives the minimum value of the discomfort level f (Y, I) of the waiting customer is T Hz < T Ha < T H3*, as shown in FIG.

Here, T)l: When emphasis is placed on irritation level, TH: When emphasis is placed on the same level.T)+3: When emphasis is placed on reservation change rate.

FIG. 14 shows the processing flow of the contents of FIGS. 12 and 13, in which the first predetermined time T□ corresponding to the allowable reservation change rate Y is determined in table FOO, and When a hall call actually occurs, step F
Calculate the estimated arrival time T^ in IO and proceed to step F1.
In step 5, the first predetermined time T□ and the predicted arrival time T^ are compared.

In step F15, if the first predetermined time T≧predicted arrival time T^, immediate reservation guidance is provided in step F20, while if the first predetermined time T1 is less than the predicted arrival time rvJT^, a second The reservation is put on hold for a predetermined time T2.

Here, how to obtain the second predetermined time T is shown in table F90.
There are method 1 shown in Figure 1 and method 2 shown in table F95. Method 1 is a method of finding a value that minimizes the discomfort level f (Y, I) of waiting customers for the predicted arrival time T^ at that time, and setting that value as the second predetermined time T2. Second
The value of the predetermined time T2 varies. In addition, method 2 calculates in advance a value that minimizes the discomfort level f (Y, I) of waiting customers for the first predetermined time T, and then uses that value for the second predetermined time T.
2, and in this case, the value of the second predetermined time T2 is constant.

〔Effect of the invention〕

As explained in detail above, according to the present invention, when the predicted arrival time is short, the reservation information is provided immediately, and when the expected arrival time is long, the reservation information is provided after a predetermined time has elapsed. You can have a guideline and can wait for the service elevator with peace of mind.

Furthermore, since customers can freely change the target value of the reservation change rate, it is possible to construct a group management system that is individualized for each building.
