Description

[Detailed description of the invention] The present invention relates to an elevator group management control device,
In particular, the present invention relates to a group management control device suitable for guiding and displaying the approach of a service elevator.

In conventional service elevator guidance displays, when a hall call occurs, the most suitable elevator for the call is selected and the selected elevator is displayed as a service elevator at the entrance/exit of the elevator. Therefore, customers waiting in the hall can easily know which elevator will serve them among the many elevators installed side by side. However, the service reservation lights installed in the hall only indicate which of the parallel elevators will arrive, and whether the service elevator will arrive in 15 seconds or 1 minute. can't know. By the way, if the waiting time is displayed in the hall, the structure becomes complicated and expensive.

The present invention has been made in view of the above, and an object of the present invention is to provide an elevator group management control device that can not only guide service elevators but also indicate that the elevators are approaching using the same service display. It is about providing.

Features of the present invention include a first means for guiding that the elevator is a service elevator that services the hall call by setting a service indicator provided at each floor landing for each elevator to a first state, and a hall of the service elevator. When the predicted arrival time for a call falls within a predetermined value determined by learning calculation using the reservation hit rate of each pattern as a criterion, the service display is set to a second state different from the first state. second means for providing guidance that the service elevator is approaching; and when the service indicator is placed in a second state by the second means, the service elevator is directed to the floor where the assigned hall call has occurred. The present invention is further provided with means for prohibiting the assignment of other hall calls to the service elevator until the service elevator arrives.

The present invention will be described in detail below with reference to the embodiments shown in FIGS. 1 to 3 and 5 to 7, as well as FIGS. 4 and 8.

FIG. 1 is a block diagram showing an embodiment of the group management control device of the present invention. In addition, in the following explanation,
A case will be explained in which the service floors are 24 floors (1st to 24th floors) and there are 3 elevators (1st to 3rd). In FIG. 1, a signal sent from a hall call button is stored in a hall call registration device 1, and the registered hall call is inputted to a group management processing device 3 through an interface 2. The most suitable elevator is selected, and the unit controllers 4a to 4c are
For example, the car control device 4a and the service reservation display 5 corresponding to the selected elevator.
A signal is sent to the service reservation display 5a of a to 5c. In response to this signal, the service reservation display 5a lights up to guide customers waiting in the hall to the service elevator, and the elevator responds to the call and arrives.

FIG. 2 is an explanatory diagram for explaining the overall operation of the group management control device of the present invention. In Figure 2,
When the hall call button 9 is pressed, the resulting signal is stored in the memory 10, and the signal is further sent to the allocation control circuit 20, which inputs the signal from the predicted arrival time table 30 to make the hall call. The optimum elevator for servicing the elevator is selected, the signal a is given to the drive control circuit 40, and the drive control circuit 40 sends a signal to continuously light up the service reservation light of the selected optimum elevator. Further, when the arrival detection unit 50 detects that the service elevator is about to arrive and has started decelerating, the detection signal is sent to the drive control circuit 40, and the drive control circuit 40 changes the service reservation light from continuous lighting to blinking. Change to

By the way, in FIG. 2, the signal a from the allocation control circuit 20 is transmitted to the approach notification allocation control circuit 6.
It is also given to 0. Approach notification allocation control circuit 60
is a circuit for displaying approach guidance when the predicted arrival time for a hall call falls within a predetermined value, and its signal b is output to the drive control circuit 40;
Accordingly, the drive control circuit 40 outputs a blinking signal to the service reservation light 70.

In addition, the pattern signal etc. from the pattern detection circuit 80 is input, the reservation accuracy is learned for each pattern as a judgment criterion, a predetermined value suitable for the building is determined, the predetermined value is set with the setting device 90, and approach notification is sent. An approach notification time limit learning circuit 100 is provided to input the predetermined value into the allocation control circuit 60.

FIG. 3 is a diagram showing the table structure of the memory 10 of FIG. 2. As shown in Figure 3, the table configuration is from the 1st floor to the 24th floor in the upward direction (UP).
It is arranged from the 1st floor to the 24th floor in the descending (DN) direction, and the direction signals for each floor are recorded here.

FIG. 4 is a time chart showing the relationship between each signal sent to the drive control circuit 40 in FIG. Indicates the lighting cycle.
When assignment occurs, the drive control circuit 40 inputs the signal a and provides the service reservation light 70 with a signal for continuously lighting the service reservation light 70. Also,
When the predicted arrival time falls within a predetermined value, the drive control circuit 40 inputs the signal b and turns on the service reservation light 7.
A signal for blinking 0 at a slow cycle is given to the service reservation 70 with priority over the continuous lighting signal, and the service reservation light 70 is blinked at a slow cycle. When the arrival detection unit 50 outputs a detection signal indicating that the service elevator is about to arrive, the drive control circuit 40 gives top priority to a signal that causes the service reservation light 70 to blink at a fast cycle. Service reservation light 70
changes to blinking at a rapid cycle to notify customers waiting in the hall that the elevator is arriving.

FIG. 5 is a flowchart of processing in the approach notification allocation control circuit 60 of FIG. First, step
Set the initial value to 200. Next, in step 210, it is determined whether there is an assigned hall call or not, and if there is no assigned hall call, the process advances to step 250.
Reset the approach notification allocation table. Also,
When there is an assigned hall call, in step 220, it is determined based on the signal from the predicted arrival time table 30 whether the predicted arrival time of the assigned service elevator is within a predetermined time limit for displaying a guidance that the elevator is approaching; Steps if available
At 230, the approach guidance display signal b is set and output. Further, the approach guidance display signal b is not set unless the estimated time of arrival of the assigned elevator is within the predetermined time for guidance display that the estimated arrival time of the assigned elevator is approaching. Then, in step 240, it is determined whether the processing for all hall calls has been completed, and if it is another hall call, the process returns to step 210 and the same processing is repeated.

FIG. 6 is a table configuration diagram of the predicted arrival time table 30 of FIG. 2, which is divided by floor for each car.

FIG. 7 is a table configuration diagram of the pattern detection table of the pattern detection circuit 80 of FIG. 2, which is divided into work, normal, quiet, clock out, lunch, etc.

Figure 8 is a diagram showing the relationship between the reservation success rate and the hall call duration time using state patterns (normal, clocking out, lunch) as parameters, where curve _l1 is normal, curve _l2 is clocking out, and curve l2 is clocking out. l ₃ indicates lunch time. According to FIG. 8, the reservation success rate during lunch time is small. Also, if you set the reservation accuracy rate to 97% (α ₁ ), it is good because the reservation accuracy rate is higher than 97% in normal times, but when you leave work or have lunch, the reservation accuracy rate is 97%. %, indicating that reservations are often not successful.

Reasons for this failure to make a reservation could be, for example, if there were three passengers who boarded from the standard floor, each car call was for a different floor, and the hall call was received after the elevator departed. If a later passenger enters another elevator from the standard floor and calls a car call to the floor with the hall call, the elevator to which the hall call was originally assigned will have a different car call. The elevator that left later will stop at the floor where the hall call is called without stopping three times, but the elevator that left later will stop at the floor where the hall call is called with only car calls.
It is conceivable that you will arrive at a better location than the assigned elevator.

As mentioned above, there is a phenomenon where the hall call duration becomes longer and the elevator that is different from the one reserved may arrive, so the user wants to increase the reservation accuracy rate to 97% or higher. If so, it is clear from FIG. 8 that the hall call duration at lunch time should be set as t ₁ and that at time of leaving work should be set as t ₂ . Therefore, if t ₁ and t ₂ are set to predetermined values for the approach guidance display, the reservation accuracy of the elevator approach guidance display can be set to 97% or more. Such processing is performed by the approach notification time limit learning circuit 100 as described above.

Furthermore, in the present invention, in order to further improve the reliability of the guidance display for the approach of the service elevator, the service reservation light 70 displays the approach guidance display (flashing).
A new hall call is not assigned to the elevator marked as , but the hall call is assigned to other elevators for which no approach guidance is displayed.

As explained above, according to the present invention, when the elevator that is most suitable for servicing the generated hall call is selected, the service indicator is set to the first state (for example, continuously lit) and the elevator is displayed to passengers. Furthermore, when the estimated waiting time becomes less than a predetermined value, the service indicator changes to the second state (blinking) to indicate that the elevator is approaching, so that customers waiting in the hall can wait for the service elevator. In addition, there is no need to change the reservation after the service reservation light indicates the approach of the elevator, which further improves the service quality.
