Abstract

PURPOSE:To inform a correct expected arrival time by combining lighting patterns of lanterns of the first lighting pattern having no relation to the expected arrival time and the second lighting pattern changed according to the expected time depending on whether the expected arrival time is more than a predetermined time or less than it. CONSTITUTION:When one of call buttons 11 to 20 at each of halls is pressed, a call signal is input to an input control part 31 and an expected arrival time of the optimal elevator is calculated based on data of a data memory part 32 to determine the optimal elevator. Moreover, an expected waiting time is calculated at a waiting time calculation part 33, and a display light control part 34 for executing lighting block number control and turning-off control of display lights at the signal generated floor (if, for example, the generated floor is the fourth floor, a display light 24 on the fourth floor) is controlled based on this expected waiting time. The number of blocks of turned-on lights and turned-off lights is changed according to, for example, whether the expected waiting time is more than 25 seconds or less than it to reduce irritation of users caused by long-time waiting at the hall.

[Purpose of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting method for an elevator hall notification device.

0002

[Prior Art] In an elevator hall notification device that uses an indicator light (hall lantern) to notify the hall call allocation car forecast and the car arrival forecast, it is generally used to notify the hall call when multiple elevators are group-controlled. Regardless of the forecast display of the allocated machine and the elevator control method,
A landing display is displayed when a car has arrived, and passengers waiting at the landing are notified of this.

The shapes of conventional hall lanterns used in such elevator hall notification devices are shown in FIGS. 6(a) and 6(a).
b), and is composed of an up-side lantern 1U and a down-side lantern 1D. The lanterns 1U and 1D are controlled to turn on and off according to the timing shown in FIG.

For example, when the up-side lantern 1U lights up to display the allocation forecast, it starts lighting at timing A, starts blinking at timing D when the allocated car arrives at the landing call floor, and then generally The light goes out at timing E when the door opens after the passenger lands on the bed and closes after the passenger gets on and off the plane.

[0005]

[Problem to be Solved by the Invention] However, with such an elevator hall notification device, it is possible to know which car will respond to a hall call that has occurred, but how long it will take for the elevator of that car to arrive. It is not possible to tell from the display how long it will take, and this may irritate the passengers waiting at the hall, especially if the waiting time becomes long, such as when the demand for elevators increases.

On the other hand, there is a system in which the hall notification device is divided into a plurality of blocks, and the lighting area of each block is increased or decreased depending on the predicted arrival time of the elevator that responds to the generated hall call. Proposed.

However, in this proposed lighting method,
The problem is that because the lighting status of the notification device and the predicted arrival time are not matched, it is not possible to notify people, such as how many seconds it will take for the elevator to arrive once a particular block is lit, which can end up irritating waiting customers. was there.

[0008] The present invention has been made in view of these conventional problems.
The lighting pattern of a hall notification device that can be controlled to turn off the lights is changed according to a first lighting pattern unrelated to the predicted elevator arrival time when the predicted elevator arrival time is above a certain level and a previous predicted time when the predicted elevator arrival time is below a certain level. The first lighting pattern is used in combination with the second lighting pattern to notify users waiting at the landing that the elevator is moving, and the second lighting pattern is used to accurately predict the arrival time of the elevator. To provide a display method for an elevator hall notification device which can alleviate the irritation of waiting customers by notifying them. [Structure of the invention]

[0009]

[Means for Solving the Problems] The present invention provides a forecast of the elevator number that will respond to a hall call to users waiting at a hall,
Further, in an elevator hall notification device, which is equipped with an indicator light to notify the arrival of the elevator that has responded to the hall call, and which is provided with lighting means that divides the indicator light into a plurality of blocks and controls turning on and off individually. The lighting control is performed based on the estimated arrival time required for the elevator assigned in response to a hall call to arrive at the floor where the hall call occurred.
Combining a first lighting pattern that is unrelated to the predicted arrival time when it is longer than a certain time and a second lighting pattern that changes in response to the predicted arrival time when it is less than a certain time,
This system notifies waiting customers of the expected arrival time of the elevator.

0010

[Operation] In the display method of the elevator landing notification device of the present invention, the turning on/off control of each block of the indicator light of each floor landing divided into a plurality of blocks is performed based on the waiting time calculation result of the corresponding landing call. By combining the lighting pattern when the time is longer than a certain time and the lighting pattern when the time is within a certain time, passengers are notified that the elevator is moving and the exact waiting time.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, in which a plurality of elevators whose operation is controlled by group management control are used to ascend and descend 10 floors of a building.

[0013] Therefore, each elevator is under overall control by a group management control device, and it is determined which car should respond to a hall call occurring at a given floor based on the result of the arrival prediction calculation of each car. The most suitable car is assigned to the hall call, and each car is equipped with a single control device that responds to its own car call and controls acceleration, deceleration, landing, etc. when arriving at the destination floor. Various types of group management control have been proposed in the past, and it is possible to use any of them.

[0014] A feature of the embodiment of the present invention is that when an actual hall call occurs, if any car is assigned to the hall call, the assigned car arrives at the hall call floor. A first lighting pattern that is unrelated to the predicted arrival time when the predicted arrival time that is predicted to take until the arrival time is longer than a certain time, and a second lighting pattern that changes in response to the predicted arrival time when it is within the certain time. It is a combination of.

FIG. 1 shows an embodiment of a hall notification device used to control the lighting of such indicator lights, and shows hall call buttons 11, 12, . Each car is provided with indicator lights (hall lanterns) 21, 22, . . . , 30 installed near it.

[0016] Also, each hall call button 11, 12,...,
An input control unit 31 that inputs the hall call signal when any one of 20 is pressed, and for the registered hall call,
It is equipped with a data storage section 32 that stores, as a table, car position information for each car, car call status information, and hall call status information that may occur on other floors.

Furthermore, based on the data in the data storage section 32, the predicted arrival time of each elevator is calculated to determine which elevator is best to be assigned to the hall call signal from the input control section 31. A waiting time calculation unit 33 that determines the allocated car by judging the size and also outputs the predicted waiting time; and this waiting time calculation unit 33.
Based on the predicted waiting time calculated by It also includes an indicator light control section 34.

As shown in FIG. 2, each of the indicator lights 21, 22, . It is divided into three stages, and the blocks a, b, and c in each stage are individually turned on and off by the indicator light control section 34. Next, the operation of the elevator hall notification device configured as described above will be explained.

As shown in the timing chart of FIG. 4 and the flowchart of FIG. 5, when a hall call occurs on a certain floor, it is determined whether the own car is the elevator that responds to the hall call, and the own car is assigned as the responding car. If so (step S1), then the predicted arrival time for that hall call (for the users of the hall call floor, this is the predicted waiting time) is calculated (step S2). This waiting time calculation method is a generally well-known method.
Calculations are performed based on data stored in the data storage unit 32, such as predicted car calls.

Next, in step S3, it is determined whether the predicted waiting time obtained in step 2 is less than a certain period of time, for example, 25 seconds, and if it is more than 25 seconds, the screen is displayed in step 5 as shown in FIG. Lights a, b, and c are turned on in sequence to inform passengers waiting at the landing that the elevator is moving. That is, in FIG. 4, from hall call generation point A to B
This display is performed for the period of the point. Further, in step S3, if the predicted waiting time is 25 seconds or less, the lighting of indicator lights a, b, and c is changed according to the predicted waiting time as described below.

In this embodiment, the indicator lights are divided into three blocks, so the predicted waiting time T is (1) 25 seconds>T>15 seconds (2) 15 seconds>T>10 seconds (3) 10 seconds>T Control is divided into three cases. Of course, if the block is divided into four or more blocks, this control is performed in stages according to the number of divisions.

If T is less than 25 seconds and up to 10 seconds, in step S6, portion a is turned on and portions b and c are turned off. That is, as in the period from point B to point C in FIG.
Only parts of it are lit. Also, T is 15 seconds or less,
In the case of up to 10 seconds, that is, in the period from point C to point D in FIG. 4, parts a and b are lit in step S7, and c
Turn off part of the light. Furthermore, when T is 10 seconds or less, that is, in the period from point D to point E in FIG. 4, all portions a, b, and c are turned on.

[0023] In this way, by increasing the number of lighting blocks of blocks a, b, and c, which are divided into a plurality of indicator lights, according to the predicted waiting time required to respond to a hall call, accurate waiting time can be obtained. Inform passengers.

[0024] Next, in step S9, it is determined whether the car has landed on the floor, and if it has landed on the floor, in step S10, after landing, the door is opened, and after the user has finished getting on and off, the door is closed. The indicator light flashes until the process is completed (
In FIG. 4, the period from point E to point F). After landing on the floor, if the passenger finishes boarding and alighting and the door is closed, step S11
Reset the indicator light as shown below. If the own car is not assigned to the hall call, in step S12, the indicator light of the own car is turned off and a flashing reset is commanded.

In this way, when an elevator of a certain number is assigned in response to a hall call and runs to the floor registered for the hall call, prediction is made when the predicted waiting time required for arrival is longer than a certain time. The first one that has nothing to do with waiting time.
By combining this lighting pattern with a second lighting pattern that changes according to the predicted waiting time within a certain period of time, the former informs the passenger that the elevator is operating, and the latter informs the passenger of the correct predicted waiting time. This will help reduce customer irritation. In addition, when responding to a car call, the indicator light will be flashed when landing on the floor, as in the past.

[0026]

As described above, according to the present invention, in order to inform passengers waiting at the hall that the waiting time changes depending on the increase or decrease in demand for elevators, the lighting pattern of the arrival notification device of the elevator at the hall can be adjusted to predict the waiting time. is divided into a first lighting pattern that is unrelated to the predicted waiting time when is longer than a certain time, and a second lighting pattern that changes depending on the predicted waiting time within a certain period of time. By informing passengers of the expected waiting time for elevators, it is possible to reduce the frustration of waiting passengers at the landing compared to having to wait longer without informing them.
