Abstract

PURPOSE:To make the stream of passengers smooth on a lobby floor and to restrain elevators from uselessly running, by providing a waiting passenger number detecting means, a cage passenger number detecting means and a door opening and closing control means. CONSTITUTION:The number of waiting passengers in a hall on a bobby floor is detected by using waiting passenger sensors 3a through 3d of laser, ultrasonic type or the like, and the number of passengers in a cage is detected by using a load detecting device in the cage. Further, during the cage stopping at the lobby floor, the number of passengers in the cage and the allowable number of boarding passengers are calculated from the load of the service elevator, and accordingly, a computer compares the number of waiting passengers with the allowable number so as to determine whether all waiting passengers can board the service elevator or not. Further, if it is estimated that passenger leaving out of boarding are present, a door opening instruction is issued to another waiting elevator. Accordingly, the waiting elevator opens its doors to cope with the waiting passengers.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a control device for a group control elevator, and particularly to a $II control device suitable for improving the efficiency of operation on a specific floor. .

[Conventional technology]

When dispatched to a hotel, rental building, or general building, etc.
There is little demand between floors, and there are many trips from the lobby floor to the destination floor. For this reason, the group control elevators are trying to strengthen the service by having elevators that have completed their service and are no longer being called on standby at the lobby floor. When a plurality of elevators are waiting at the lobby floor, the response to a hall call is divided into whether only one elevator opens its door or multiple elevators open the door at the same time. In addition, the waiting elevator
Regarding this, there is Japanese Patent Publication No. 62-34672,
This invention concerns the allocation restriction of waiting elevators to other hall calls. In addition, as for the use of a waiting sensor, there is Japanese Patent Application Laid-open No. 102044/1983, which deals with additional allocation of elevators.

[Problem that the invention seeks to solve]

Among the conventional technologies mentioned above, in the method of opening the doors of multiple elevators at the same time, if the number of waiting passengers is too small for the number of elevators, a small number of people may board each elevator and depart. There were problems in improving efficiency and in deteriorating the service to waiting passengers after departure. In addition, in a system in which only one elevator opens its doors, even if there are obviously too many passengers waiting to get into one elevator, the next elevator will be moved until a predetermined number of people (e.g. 80% of the capacity) have boarded the first elevator. is on standby and the door won't open, so you can't get on board. Therefore, it takes time for waiting passengers to board the train, which delays departure and reduces efficiency. The above problem is caused by not considering the actual number of customers waiting.

The purpose of the present invention is to smooth the flow of waiting customers on the lobby floor and to suppress wasteful elevator operation by adding the number of waiting elevator doors according to the number of waiting customers. An object of the present invention is to provide a control device for a group management elevator that can perform group management.

[Means for solving problems]

The above purpose is to provide a waiting number detecting means for detecting the number of waiting passengers in the elevator hall on the lobby floor and a means for detecting the number of passengers in the car, and to detect the number of waiting passengers detected by the waiting passenger number detecting means and the number of passengers in the car. This is achieved by combining the number of passengers detected by the number of passengers detecting means to detect the number of elevators waiting at the lobby floor and controlling the opening and closing of the doors.

[Effect]

Various methods have been devised to detect the number of waiting customers, including those using infrared rays and ultrasonic waves, those using ITV image processing, and counters and mud switches using photoelectric beams. The number of passengers is detected, and a car load detection device is used to detect the number of passengers in the car, and the number of passengers is detected based on the load of the service elevator when it is stopped at the lobby floor. The number of passengers and the number of people who can board the elevator are calculated, and the number of waiting passengers and the number of passengers who can board the elevator are compared in the microcomputer, and it is determined whether all waiting passengers can board the service elevator, and it is determined that there will be backlogs. In such a case, a door opening command is issued to other waiting elevators, and the waiting elevator receives the door opening command and opens its doors to serve the waiting customers, thereby improving the flow of waiting customers. Make it smooth and
It is possible to suppress unnecessary operation of elevators.

〔Example〕

The present invention will be explained in detail below using the embodiments shown in FIGS. 1 to 4.

FIG. 1 is an overall configuration diagram showing one embodiment of a control device for a group management elevator according to the present invention. Lobby floor elevator
Flat platform group control elevators installed in parallel to the hall - 4a to 4
Waiting sensors 3a to 3d for detecting the number of waiting customers in front of each elevator car are installed at the upper part of the elevator. The detected number of waiting customers is sent to the group management control microcomputer 2 as a sensor output. Further, the position of each car, the open/closed state of the two doors, and the number of passengers in the car are sent from the microcomputer 1 of each car to the group management control microcomputer 2 as car information 6. In addition to the existing allocation section 2a, the group management control microcomputer 2 includes a waiting customer number determination section 2.
b. A door opening/closing command section 2c is provided. The reservation information 9 is obtained from the ratio section 2a, and the clock 2d is used to measure the door opening time.
I put it.

The group management control microcomputer 2 determines whether to open or close the door by processing the flowcharts shown in FIGS. 2 to 4, and sends a door opening/closing control signal 5 to the microcomputer 1 of each machine. The machine microcomputer 1 transfers the door opening/closing control signal 5 for the car and hall doors to the door opening/closing control device 8 for control. Here, in this embodiment, the application target is a hotel where the first floor is the lobby floor and which aims to strengthen response to demand in the ascending direction.

The processing in the group management control microcomputer 2 will be described below. In Fig. 2, 1M indicates the number of standbys in the ascending direction, initial settings are made in step A1, and steps A2 to
In the loop between A6 and M, the detection of M is carried out in the waiting number format running section 2b. Here, N is the number of machines installed in parallel, and in Figure 1, N
=4. In this loop, the waiting passengers in front of the car whose reservation is announced in the downward direction from the reservation information 9 are assumed to be going to the lower floor, and are excluded at the branch in step A3.
The number m of waiting passengers in front of other cars is detected from the sensor output cuff in step A4, and is added to the number M of waiting passengers in the ascending direction in step A5. When the detection of M is completed, the presence or absence of a waiting customer is determined in step A7, and step B or C of door opening/closing command processing I or door opening/closing command processing ■ is performed by the single door opening/closing command unit 2C.
Proceed to.

FIG. 3 is a flowchart showing an example of the door opening/closing command process (2) in step B in FIG. 2 when there are no customers waiting.

Steps 81 to B9 are processes for each machine. For each car, it is determined in step B2 whether there is a car on the lobby floor, and if there is a car, it is checked in step B3 whether or not the downhill reservation notification has been received, and if the reservation notification has not been received, step In B4, it is determined whether the car whose door is closed is on standby, and if the door is open, the number of passengers P for the car is detected in step B5, and the presence or absence of passengers is determined in step B6, and P=0. If so, step B7 sets the elevator to standby with the door closed, and if there are passengers, step B7
At 8, I close the door and leave.

Next, if the loop ends at step B9, step B
Set the door open command using IO. Set the door opening command to H.
, reset is set to L, which corresponds to step C16 in FIG.
is valid. In FIG. 3, the machine information 6 read from the microcomputer 1 of the first machine is obtained at step B2. B4. At B5, the reservation information 9 is used at step B3, and the door opening/closing control signal 5 is output at steps B7 and B8.

FIG. 4 is a flowchart showing an embodiment of the door opening/closing process (2) in step C' of FIG. 2 when there is a waiting customer. The number of people who can board the car is expressed as Pa, initial setting is performed in step C1, and processing for each car is performed between steps C2 and G22. In steps C3 and C4, it is checked whether it is a car on the lobby floor that has not received a downhill reservation notification, and if it has not received a reservation notification, it is checked in step C5 whether the door is open or closed, and if the door is open, it is checked. , the process proceeds to step C6, and the number of passengers P in the car is detected. Then, in step C7, what is the number of passengers P? Check whether the number of passengers Pa for each i21 is reached, and if it is full, close the door and depart in step C14, set the door open command in step C15, and proceed to the next aircraft! If the room is not full in step C7, it is checked in step C8 whether the time since the door was opened has exceeded a certain time limit.

If it exceeds the limit, the door closing button is allowed to be used and departure is permitted in step C13. , if the number of people who can board the aircraft is not exceeded, the process goes to step C9, and the number of people who can board the aircraft is added to the number of passengers Pa (
Add P□-P). In step C10, it is checked whether the number of passengers who can board the train is greater than the number of waiting passengers M. If it is, it is assumed that all waiting passengers can board the train, and the door opening command is reset in step C1l, and the process proceeds to the next car.
If & is less than M, it is necessary to add an elevator, so it is checked in step C12 whether P > Po, and if P > Po is not, a door opening command is set in step C15. At that time, in step C12, P
If the number of people exceeds a certain number Pa, such as 80% of the capacity, the door opening button is enabled in step C13.

Next, when the door of No. 1 is closed, the process branches from step C5 to step C16. This process is performed in the standby elevator. If the door close command is L in step C16, there is no need to open the door, and the process proceeds to the next car. If it is set, an additional door opening of the standby elevator is executed in step C17, and the door opening time is determined in step C18. The timer is started, and P& is corrected in step C19. In addition, since this elevator departs later than the elevator whose door is already open, the door close button is disabled at step (20) to prevent a small number of passengers from leaving the elevator.
In order to prevent the door from opening more than necessary in step C21,
Reset the open command. In step C22, the end of the loop is detected. In FIG. 4, the machine information 6 retrieved from the machine microcomputer 1 is used in steps C3, C5, and C6, the reservation information 9 is used in step C4, and the door opening/closing control signal 5 is output in steps C12, C15, C16, and C18.

When the execution of the door opening/closing command process (1) or (2) is completed, one process in FIG. 2 is completed. This process is repeated taking into consideration traffic flow, car size, etc.

According to this embodiment, by detecting waiting passengers for each car, it is possible to treat passengers traveling in the ascending direction, whose services are to be strengthened, by distinguishing them from passengers traveling in the descending direction. In addition, when there is no passenger, the door of the waiting elevator is closed, but since the door opening command is set in step BIO in Figure 3, there will be no door opening for the waiting passengers. Since it is determined that an additional door is to be opened, the service elevator in the ascending direction can respond to the door opening without having to issue a hall call.

〔Effect of the invention〕

According to the present invention described above, it is possible to allocate waiting elevators in accordance with the number of waiting customers on the lobby floor.
This has the effect of suppressing unnecessary elevator operations and smoothing the flow of waiting customers on the lobby floor.
