Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a platform notification device used as a peripheral device of an elevator group management control device, and is particularly suitable for elevators where a plurality of elevators are assigned. The present invention relates to a platform notification device.

[Conventional technology]

Conventional elevator landing notification devices were attached to a group management control device that was characterized by assigning only one elevator to a hall call that occurred, and the number of elevators was assigned to the hall call. It merely had the function of notifying the public. For this reason, when implementing a group management system for elevators that can assign multiple units, it is necessary to
It is not possible to provide waiting passengers with information such as which planes are assigned or available for boarding, and which plane will arrive at the floor first, leading to confusion and dissatisfaction when waiting passengers prepare to board the tower. There was a fear that it would cause

In addition, in Utility Model Application No. 54-173475, a method was devised to display the estimated arrival time inside the carts, but simply displaying this in front of each cart in the hall may cause confusion for waiting customers. was there.

[Problem that the invention seeks to solve]

The above conventional technology does not consider the case where multiple elevators are assigned to calls in the same direction of the call-generating hall, and when multiple elevators are assigned, the arrival order of the elevators is not considered. The problem was that the information could not be communicated in an easy-to-understand manner.

An object of the present invention is to safely guide waiting customers to the elevator without causing confusion or discomfort to the waiting customers even when a plurality of elevators are assigned.

[Means for solving problems]

The above purpose is to ensure that one or more cars of the same number arrive at the floor or the assignment is canceled from the time the car is assigned for a hall call or the stop of the car for the floor is confirmed due to an in-car call. This is achieved by calculating the predicted arrival time until then and displaying the arrival order or predicted arrival time of the assigned car and the available cars.

[Effect]

In the present invention, when a plurality of elevators are assigned to a hall call floor and stopped in a state where the elevators can be boarded due to the call in the car, the notification device at the elevator landing is configured to notify the waiting passengers of the order of arrival of those elevators or the predicted arrival time. can be informed. Thereby, waiting customers can be safely guided to the elevator without causing confusion or discomfort to the waiting customers.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 4 is a block diagram of one embodiment of the present invention. The elevator landing notification device is connected to an elevator group management control device that can allocate multiple elevator numbers to a hall call. The notification device receives elevator operation status data from the group management control device.

Further, the notification device is connected to a display device provided for each car in each hall on each floor, and sends display data to one display device.

It is assumed that the programs described below are managed under the operating system (O8), which is a system program that divides the program into a plurality of tasks and performs efficient control. Therefore, the program can be started freely from the system timer or from other programs such as the group management control program.

FIG. 1 is a program flow chart showing one embodiment of the present invention. This program is activated periodically, for example, every second. In step A30 after steps AIO and A20, it is determined whether a hall call is registered in the registration device in the up direction or down direction of the nth floor. If it is determined that the arrival prediction table is not registered, the process advances to step A90, where the arrival prediction table is reset, and then the process advances to step A100. On the other hand, if it is determined that it is registered, step A50 is performed after passing through step A40.
At this point, it is determined whether a car has been assigned to the floor and in that direction, or whether the car has been stopped and ready to board due to an in-car call, that is, whether there is a service scheduled. If it is determined that there is no service scheduled, the process proceeds to step A80. On the other hand, if it is determined that there is a service scheduled, the predicted arrival time is determined in step A60, and then the arrival time is determined in step A70. The predicted arrival times and car numbers are set in the arrival prediction table in descending order of arrival time. After completing the above processing for all elevators from Steps A40 to A80, in Step A110 via Step A100, the predicted arrival order and predicted arrival time are determined according to the arrival prediction table from the first car of the nth floor to which the call is registered. The predicted arrival order and predicted arrival time of each car are set on all display devices corresponding to the car.

FIGS. 2(a), 2(b) and 2(c) are explanatory diagrams of a display device at a boarding point showing an embodiment of the present invention.

PL is an indicator light and DP is a display screen. In the case of a machine that has a service schedule for a hall call, Example (a)
), the indicator light is turned on and the predicted finish order is displayed on screen D.
In (b), the indicator light is turned on and the predicted arrival time is displayed on the display screen DP, (c)
Then, the predicted arrival order or predicted arrival time is displayed with meaning by a combination of display lighting time and light-out time (flicker blinking frequency) (described later in FIG. 3). In the above embodiments (a), (b), and (c), if the car is not scheduled for service in response to a hall call, the indicator light is turned off and no other display is performed on the display device. Also.

On the above-mentioned money side, the display color of the indicator light is green if the car is permanently assigned to the called floor (including service to that floor by in-car call), and red if it is tentatively assigned. It is also possible to change the display color by

FIGS. 3(a) and 3(b) are explanatory diagrams of a lighting/extinguishing method for indicator lights of a display device showing one embodiment of the present invention. In the embodiment (a), the predicted arrival order is displayed based on a combination of periodic lighting times and lights-out times. Also, in (b),
Similarly, the predicted arrival time T is set in a predetermined time range (for example, T,
<T≦Tn+sHn = 1, 2...). These are executed by other programs not shown.

〔Effect of the invention〕

According to the present invention, when a plurality of elevators are assigned to a hall call floor and stopped in a state where the elevators can be boarded due to car calls, the order of arrival or predicted arrival time of those elevators can be notified to waiting customers. This has the effect of safely guiding waiting customers to the desired elevator without causing confusion or discomfort to the waiting customers.
