JP5081875B2 - Platform destination floor reservation type elevator group management system - Google Patents

Description

  The present invention relates to a group management system that manages and manages the operation of a plurality of elevators, and in particular, has a landing destination floor reservation function for registering a destination floor at a landing before getting on an elevator car (hereinafter referred to as a car). It relates to an elevator group management system.

  The elevator group management system provides a more effective operation service to the user by handling a plurality of cars as one group. Specifically, when multiple cars are managed as one group, and a landing destination floor is registered on a certain floor, one optimal car is selected from this group and the car is placed on that car. A process for assigning a call is performed.

  Destination floor reservation system type group management (hereinafter referred to as destination floor reservation type group management) is a group management in which a destination floor is registered with a destination floor reservation device provided at a landing before boarding a car. It is.

  In general group management, an up or down call is registered at the landing and the destination floor is registered after the car arrives, whereas the destination floor reservation type uses it at an early stage for the control device. Since the destination floor of the person is known, a more optimal car can be assigned according to the destination floor. However, the user who came to the landing cannot know which floor is registered, and as a general rule, all waiting passengers make reservations for the desired destination floor.

  If there are many users waiting at the platform, as with general elevators, it is not possible to carry all of them with one car, and even if the car is pre-assigned and known at the destination floor reservation type, Since the boarding place is congested, there are cases where it is not possible to get into the assigned car, and the user who fails to ride again must register the destination floor with the destination reservation device and wait for the next car to arrive. In order to alleviate such congestion at the platform and to eliminate unloading, there are conventionally proposed restrictions on destination floor registration and guidance on the congestion situation and the like.

  Next, conventional techniques related to the destination floor reservation described above are listed below. Patent Document 1 shows an example in which destination floor reservation type group management is provided with means for restricting destination floor hall call allocation based on the number of waiting passengers. Patent Document 2 shows an example in which destination floor reservation type group management has a function of displaying guidance according to the congestion situation and waiting time of a specific floor. Patent Document 3 declares a guide that suppresses or prevents inconvenient allotted hall call and car call registration, such as services in which the elevator returns past the guidance display floor, although it is not the destination floor reservation group management. An example of blocking the assignment of the corresponding elevator is shown.

JP 2007-55782 A JP 7-277623 A JP 7-69551 A

  In the prior arts disclosed in the above Patent Documents 1, 2, and 3, if there are more waiting users at the landing than the number of people who can get on the elevator, the destination floor registration by the user cannot be restricted, It cannot be said that the congestion at the current platform is alleviated.

  In the example shown in Patent Document 1, the expected waiting rate is calculated from the destination floor call non-occurrence interval and the number of times the destination floor call is registered, and until the assigned car arrives at the currently generated destination floor call. The number of waiting passengers is predicted, the maximum number of passengers in the predicted elevator car is calculated, and calls are restricted. Even if calls are restricted, call registration is possible, so if there are a large number of users, there is a possibility that they cannot be used even if they are registered.

  In the example shown in Patent Document 2, when a car of a certain car is congested and nearly full, guidance to a car that is crowded with passengers is avoided by a car crowded display. Call registration is possible even when the car is congested, so if there are many users, there is a possibility that it cannot be used even if registered.

  In the example shown in Patent Document 3, guidance that suppresses or prevents inconvenient assignment hall call and car call registration is declared to prevent assignment of the corresponding elevator. Registration can be suppressed by guidance, but registration may not be completely prohibited for users.

  It is an object of the present invention to display a destination floor registration error corresponding to the congestion of the landing floor for destination floor registration in the destination floor reservation type group management, prohibit the destination floor registration, and wait without entering the landing floor. It is to provide an elevator group management system for informing the user.

In order to solve the above problems, the present invention mainly adopts the following configuration.
A plurality of elevators, an elevator control device that controls each elevator, a group management control device that is connected to the elevator control device and manages the operation of the plurality of elevators, and is connected to the group management control device An elevator group management system comprising a destination floor reservation device for reserving an elevator destination floor provided at a landing,
The group management control device receives the input of the landing destination floor in the destination floor reservation device, calculates the waiting number of people on the landing, and based on the calculated waiting number of people, the predicted number of people in the car at the time of departure from the landing is a predetermined number of people If the destination floor reservation device is not displayed on the destination floor reservation device without displaying the elevator allocated in the plurality of elevators when the destination floor reservation device is displayed. The predetermined number of people is the normal time zone of the person waiting at the landing, the situation of the passengers in the time zone, and the actual number of passengers at the time of over capacity warning It is a configuration that is calculated from data obtained in advance with respect to the relationship with the specified car capacity, and is a variable value without being limited to the specified car capacity.

  According to the present invention, when the platform is congested, destination floor registration is prohibited in destination floor reservation type group management, and a user who newly registers a destination floor is instructed to wait in front of the destination floor reservation device. As a result, it is possible to suppress the congestion at the landing and to get on the car that has been reliably allocated.

It is a block diagram which shows the structure of the landing destination floor reservation type elevator group management system which concerns on embodiment of this invention. It is a flowchart which shows the procedure of the destination floor reservation and registration in a platform congestion state in the platform destination floor reservation type elevator group management system which concerns on this embodiment. It is explanatory drawing which shows the condition of the platform congestion state in the platform destination floor reservation type elevator group management system which concerns on this embodiment.

  A landing destination floor reservation type elevator group management system according to an embodiment of the present invention will be described below in detail with reference to the drawings. In the drawing, 10 is a group management device, 101 is a predicted arrival time calculation unit for each car at the landing call generation floor, 102 is a floor stop frequency calculation unit for each car, 103 is an assigned car selection unit, and 104 is a destination floor registration. Number of times calculation unit 105, number of people in departure predicted car number calculation unit 106, destination floor registration prohibition determination unit 20, destination floor reservation device 30-32 elevator control device 40-42 elevator device 51 Numeral 56 represents an elevator car, 61 to 64 represent destination floor reservation devices, 71 and 72 represent passengers, and 80 represents a landing.

  The elevator group management system having a landing destination floor reservation function shown in FIG. 1 is group management using a system in which a destination floor is registered at a landing and a car is assigned according to the destination floor. The elevator group management system according to this embodiment includes, for example, six elevator control devices 30, 31, and 32, elevator devices 40, 41, and 42, a destination floor reservation device 20, and a group management device from Unit A to Unit F. 10. Each of the elevator apparatuses 40, 41, and 42 includes a car, a hoisting machine, a weight, and a rope. FIG. 1 illustrates only the elevator car and the rope.

  In the group management device 10 of the elevator group management system according to the present embodiment, the selection unit 103 selects a car (for example, any one of cars from A to F) for the destination floor reservation at the landing. . Here, as an example, there is a case where a passenger on the second floor landing reserves and registers the fifth floor as a destination floor.

  As the group management device 10, the estimated arrival time calculation unit 101 for each car at the call generation floor (eg, the second floor) calculates the estimated arrival time of each car at the floor where the call is generated (eg, the second floor). It is calculated from the current position, direction, speed, landing call and destination floor call status. In the stop count calculation unit (count calculation unit for the number of stops at each car floor) 102 of each car, there is a call at the landing assigned to each car (whether or not there is a call at the stop assigned to the car). Or) predict the number of car stops (number of stops on the floor) from the destination floor of the call. In the car assignment, since the destination floor is known first, the number of stops of each car is suppressed and assigned so as to be equalized. Based on the calculated information, the assigned car selection unit 103 selects the most appropriate one of a plurality of elevators (for example, Unit A to Unit F).

  Further, the destination floor registration count calculation unit 104 counts the number of registrations in the destination floor reservation device 20, and based on the count value (the number of people waiting at the platform 80), the number of people in the car upon arrival, the number of passengers getting off, and the like. Then, the number of people in the predicted car at departure is calculated by the calculation unit 105 (eg, the number of people in the predicted car at departure on the second floor is calculated). The destination floor registration prohibition determination unit 106 determines the number of people in the car at the time of departure and a predetermined value (for example, the predetermined value may be a capacity within the car, but there is a difference in the weight of the passengers, so the number is not limited to the capacity within the car). And determining whether or not to prohibit destination floor registration at the platform (eg, 2nd floor).

  If the determination unit 106 determines that the destination floor registration is prohibited, the selection unit 103 does not select the assigned car, displays an error on the destination floor reservation device 20, and disables destination floor registration. If it is determined that the registration of the destination floor is not necessary (eg, if the predicted number of passengers on the second floor is less than the capacity in the car), the most appropriate unit is assigned and sent to the destination floor reservation device 20 for assignment. The displayed unit is displayed. Thus, the configuration of the elevator group management system shown in FIG. 1 has the functions and operations described above.

  Next, with reference to the flowchart of FIG. 2, description will be given of determination of a landing congestion state and display of a destination floor reservation device at that time in the elevator group management system according to the present embodiment.

  First, when the destination floor (eg, the fifth floor) is input at the destination floor reservation device 20 at the landing (eg, the second floor) (ST01), the destination floor (eg, the fifth floor) is displayed on the destination floor reservation device 20. (ST02). Next, the number of registrations in the destination floor reservation device 20 is counted, and the number of waiting places at the landing (eg, the second floor) is calculated (ST03). Using this count value, the predicted number of passengers at the time of departure from the platform is calculated (ST04).

  In other words, the predicted number of passengers getting off at the time of arrival is subtracted from the predicted number of passengers at the time of arrival at the same platform (eg, the second floor) obtained by the destination floor reservation device 20, and the corresponding platform (example) is calculated in (ST03). By adding the number of people waiting on the second floor), the predicted number of passengers in the car at the time of departure from the landing (eg, second floor) is determined (ST04). Compare the predicted number of passengers in the car at the time of departure for the currently assigned unit with the number of passengers in the car (there may be a predetermined value that is not limited to the number of cars in the car because there is a difference in passenger weight). Thus, it is determined whether or not the destination floor registration is prohibited (ST05). The above-mentioned predetermined value (predetermined number of people) is the regular time zone of the person waiting at the landing (time zone immediately after the end of working hours), the situation of the customer in this time zone, the specified capacity in the car and the actual Considering data related to the number of passengers (at the time of warning of over-capacity), etc., the value can be changed without being limited to the specified capacity within the cage.

  If the estimated number of passengers in the car at the time of departure is less than or equal to the capacity of the car, all users waiting at the landing can be boarded and it can be determined that it is not congested. The assigned machine (eg, machine A) is displayed on the device 20 (ST06). Thereafter, the display is turned off (ST09).

  On the other hand, if the number of passengers in the car at the departure point (eg 2nd floor) exceeds (or exceeds) the number of passengers in the car, all the passengers waiting at the boarding place cannot get on and can be judged as being congested. Then, an error (display example .--) is displayed on the destination floor reservation device 20 (ST07), and registration is prohibited (the assigned machine is not displayed and registration is prohibited with an error display. Immediately after the destination floor registration is prohibited, the destination floor reservation device 20 may have a function of displaying and / or notifying in advance so that the user can recognize that registration to the same destination floor is impossible. (Good), since it is crowded with the users, it is notified to stand by in front of the destination floor reservation device 20 (ST08). As shown in FIG. 3 to be described later, when a plurality of destination floor reservation devices 61 to 64 are installed at one landing, when destination floor registration is prohibited by one destination floor reservation device, all destination floors are reserved. The reservation apparatus is linked so that an error is displayed and registration prohibition is displayed.

  In FIG. 2, the standby notification is described following the error display. However, the standby notification may be used instead of the error display. That is, as will be described later with reference to FIG. 3 (B), immediately notify the user to wait in line in front of the destination floor reservation device 62 without entering the platform 80 (a passenger who is prohibited from registering the destination floor will receive the platform). If it enters 80, the platform 80 becomes congested for customers who use the assigned machine D, and there is a possibility that it will be missed). After that, if the assigned car stops and stops at the destination floor, the condition is changed, so that the display is turned off based on that (ST09).

  As described above, the congestion status of the platform is determined based on the number of registrations of the destination floor (ST05), and the reservation of the destination floor is prohibited at the time of congestion (error display and / or notification without displaying the assigned unit) By doing so, congestion at the landing can be suppressed.

  Next, functions and operations of the elevator group management system according to the present embodiment will be described with reference to FIG. FIG. 3 is an image view of the elevator hall at the time of congestion. FIG. 3A shows a case where destination floor registration is not prohibited during congestion (when the procedures of ST03, ST04, ST05, ST07, and ST08 in FIG. 2 do not exist), and FIG. 3B shows the functions of this embodiment. -This is to illustrate the action, and shows the case where destination floor registration is prohibited during busy times.

  It is assumed that the user 71 performs destination floor registration with the destination floor reservation device 62 and the No. D machine 54 is assigned. In FIG. 3 (A), since all the users 72 who have registered the destination floor have entered the landing 80, it is very crowded. Therefore, there is a possibility that the user 71 immediately after the destination floor registration will fail to get on even if the assigned car D arrives because the customer who has accumulated at the landing 80 becomes an obstacle. It is also possible that other passengers cannot board.

  On the other hand, in FIG. 3B, the destination floor reservation device 62 and the group management device 10 count the number of destination floor registrations to calculate the number of people that can enter the car, and wait for only that number of users at the platform 80. By prohibiting other users from entering the destination floor reservation device 62 (for example, by displaying errors and / or notifications in ST07 and ST08, and turning off the display in ST09), by not entering the landing ( (For example, by aligning in front of the destination floor reservation device 62 in ST08 and notification of waiting), the crowded state of the landing is avoided, and the user 71 registered earlier or having a different destination floor is surely assigned. You can board the D-machine 54.

  As shown in FIG. 3 (B), the destination floor reservation device 62 and the group management device 10 determine the congestion state of the landing 80 and restrict entry to the landing 80, thereby failing to get on the assigned car. It can be suppressed and transportation efficiency can be increased.

  As described above, the embodiment of the present invention is characterized by having the following configuration. That is, in the landing destination floor reservation type elevator group management system, if the predicted number of passengers at the departure point calculated based on the number of destination floor registrations for each elevator exceeds the predetermined value (capacity limit), a registration error will occur. It has a function for displaying and prohibiting destination floor registration and a function for guiding and notifying a user without entering the landing when destination floor registration is prohibited. More specifically, in the destination floor reservation type group management, the car at the time of departure from the currently assigned car (eg, 2nd floor) for the destination floor reservation (eg, 5th floor) of the boarding place. The number of passengers is estimated from the number of registrations at the landing destination floor (number of people waiting for the landing (eg, 2nd floor)), the predicted number of passengers in the car upon arrival, and the predicted number of passengers on arrival. Compare the number of passengers with the number of passengers in the car, and if the number of passengers exceeds the number of passengers in the car, the destination floor registration error is displayed and the destination floor registration on the destination floor reservation device is prohibited. This is a notification.
