Description

An embodiment of the present invention relates to a boarding position display system and an elevator apparatus.

In recent years, preventive measures against infectious diseases such as novel coronaviruses and influenza viruses have been encouraged. Therefore, in places where there is a risk of crowds such as commercial facilities and office buildings, in order to ensure so-called social distancing, we will display marks indicating the standing position in front of the store and the passageway in front of the cash register, and a certain social distance. We are making announcements to secure the distance.

However, in a car such as an elevator, the optimum boarding position differs depending on the number of passengers actually boarding. For example, when four passengers board the car, the optimum boarding position is in the vicinity of the four corners of the car, but when five or more passengers board the car, the center of the car is also the optimum boarding position.

As described above, since the optimum boarding position differs depending on the number of passengers, it is difficult to indicate the boarding position in advance on the floor of the elevator car with a sticker or the like. In addition, if the boarding position is indicated by a sticker or the like, the sticker needs to be reapplied when the boarding position is to be changed. For this reason, it becomes difficult to operate according to the congestion situation of the elevator.

As a conventional technology, an elevator system has been proposed that displays the boarding position of the elevator to passengers. However, this technology does not change the boarding position according to the number of passengers in the elevator to ensure social distance between passengers.

Japanese Patent No. 6683181

In the elevator apparatus 10 configured as described above, the CPU 81 controls the drive unit 91 based on the input from the operation panel 36 . For example, when the CPU 81 forwardly rotates the lift motor 40 via the drive unit 91, the car 31 is lifted and the counterweight 50 is lowered. When the CPU 81 reverses the elevation motor 40 via the drive unit 91, the car 31 is lowered and the counterweight 50 is raised.

In addition, the CPU 81 selects a predetermined flat light source 35 according to the preset number of passengers in the car 31 and lights the selected flat light source 35 via the power supply unit 92 . The operation of driving the planar light source 35 will be described below.

The set number of passengers is the number of passengers who can easily secure a certain social distance between passengers when they board the car 31 . The set number of passengers can be determined based on the capacity of the car 31 . For example, when the capacity of the car 31 is 20 people, by setting the number of passengers to 10 or less, it is possible to secure a social distance between passengers to some extent. Therefore, for example, when the operating rate of the elevator apparatus 10 is low, the set number of passengers is set to 4, and when the operating rate is high, the set number of passengers is set to 9.

When the car 31 stops at the boarding/alighting position, the CPU 81 detects the number of passengers waiting at the boarding/alighting position based on the image information from the camera 37, and sets the set number of passengers according to the detection result. For example, when the number of passengers waiting for the car 31 to arrive at the boarding/alighting position is less than the threshold, the set number of passengers is set to 4, and when the number of passengers is equal to or greater than the threshold, the set number of passengers is set to 9. The above threshold is determined by, for example, the installation environment of the elevator apparatus 10 and the transportation capacity of the elevator apparatus 10 .

The CPU 81 selects the planar light source 35 according to the set number of passengers, and lights the selected planar light source 35 . As a result, the boarding position in the car 31 is displayed. FIG. 7 is a diagram showing boarding positions PO when the set number of passengers is four. When the set number of passengers is 4, the CPU 81 turns on the four planar light sources 35 to display the four boarding positions PO. Specifically, the CPU 81 turns on the planar light sources 35 (2, 2), 35 (2, 5), 35 (5, 2), and 35 (5, 5) so that the floor surface of the car 31 is 4 display one boarding position PO.

FIG. 8 is a diagram showing boarding positions PO when the set number of passengers is nine. When the set number of passengers is 4, the CPU 81 turns on the 20 planar light sources 35 to divide the floor of the car 31 into 9 sections and display 9 boarding positions PO. Specifically, the CPU 81 controls the planar light sources 35(1,1), 35(1,2), 35(2,1), 35(2,2) and the planar light sources 35(1,5), 35( 1,6), 35(2,5), 35(2,6) and plane light sources 35(3,3), 35(3,4), 35(4,3), 35(4,4) and , plane light sources 35(5,1), 35(5,2), 35(6,1), 35(6,2) and plane light sources 35(5,5), 35(5,6), 35( 6, 5) and 35 (6, 6) are lit to divide the floor surface of the car 31 into 9 sections and display 9 boarding positions PO.

The lighting pattern of the planar light source 35 described above is stored in the auxiliary storage section 83 of the control unit 80 in association with the set number of passengers. The CPU 81 selectively lights the plane light source 35 in a pattern corresponding to the set number of passengers.

As described above, the elevator apparatus 10 according to the present embodiment can display arbitrary boarding positions on the floor surface of the car 31 according to the number of passengers waiting at the boarding/alighting positions of the elevator system 10 . Therefore, it is possible to display the optimum boarding position according to the number of passengers. Thereby, the social distance between the passengers of the car 31 can be ensured.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, in the above embodiment, the CPU 81 set the set number of passengers based on the image information from the camera 37 . Not limited to this, the CPU 81 may set the set number of passengers according to the time zone. For example, the set number of passengers may be set to 9 during times when the operating rate of the elevator apparatus 10 is relatively high, such as commuting and lunch hours, and the set number of passengers may be set to 4 during other time periods. Also, the set number of passengers may be set by an administrator of the elevator apparatus 10 .

In the above embodiment, four or nine boarding positions are displayed PO. The present invention is not limited to this, and the number of boarding positions PO other than four or nine may be displayed.

In the above embodiment, the planar light sources 35 are arranged in a matrix of 6 rows and 6 columns. Instead of being limited to this, the flat light sources 35 may be arranged in a matrix of 7 rows and 7 columns or more, for example. Alternatively, they may be arranged in a matrix of 5 rows and 5 columns or less.

In the above embodiment, the boarding position is displayed by lighting the planar light source 35 . The light source for displaying the boarding position is not limited to a planar light source, and any light source that can be turned on and off at will may be used. For example, instead of the planar light source 35, a liquid crystal display, an organic EL display, or the like may be arranged on the floor of the car 31. FIG. FIG. 9 shows a liquid crystal display 95 arranged on the floor of the car 31. As shown in FIG. Any image can be displayed on the floor of the car 31 by using the liquid crystal display 95 . Therefore, the CPU 81 can display the boarding position PO using, for example, a circular or square frame.

FIG. 10 is a diagram showing a projection device 96 provided on the car 31. As shown in FIG. As an example, as shown in FIG. 10, instead of the liquid crystal display 95, a projection device 96 such as a projector provided on the ceiling or wall of the car 31 is used to display the boarding position PO on the floor. good too.

When using the liquid crystal display 95 or the projection device 96, for example, as shown in FIG. 11, it is possible to display a number indicating the stop floor of the car 31 together with the boarding position PO. For example, the CPU 81 may recognize the number indicated by the passenger positioned at the boarding position PO based on the image information from the camera 37, and stop the car 31 at the floor indicated by the number. The passenger can notify the CPU 81 of the destination floor by, for example, standing where the numbers are displayed.

In the above embodiment, the plane light source 35 is turned on to display the boarding position PO. For example, when the passenger is positioned at the displayed boarding position PO, lighting of the flat light source 35 indicating the boarding position PO may be stopped. As a result, only the boarding positions PO where there are no passengers are displayed, making it easier for new passengers to access the boarding positions PO.

In the above embodiment, the CPU 81 lights the plane light source 35 to display the boarding position PO to the passengers. The CPU 81 may use a speaker (not shown) to announce boarding to the boarding position PO to the passengers along with the display of the boarding position PO. Further, the announcement may be made, for example, when the CPU 81, based on the image information from the camera 37, deviates from the displayed boarding position PO of the passenger.

The CPU 81 may display the boarding position PO based on the image information of the camera 37, for example, based on the attributes of the passengers waiting at the boarding/alighting position, so that the related passengers are located nearby. For example, when the CPU 81 determines that the passengers are a parent and child based on the image information from the camera 37, the boarding positions PO may be displayed such that the two passengers are adjacent to each other. In this case, it is conceivable to display the adjacent boarding position PO by blinking the planar light source 35 .

In the above embodiment, as shown in FIG. 8 as an example, the planar light sources 35 that are lit and the planar light sources 35 that are not lit are used to display the nine boarding positions PO. Alternatively, for example, the boarding position PO may be displayed by using the planar light sources 35 capable of emitting light in a plurality of colors and causing the respective planar light sources 35 to emit light in different colors.

For example, in this case, the CPU 81 controls the planar light sources 35(1,1), 35(1,2), 35(2,1), 35(2,2) and the planar light sources 35(1,5), 35( 1,6), 35(2,5), 35(2,6) and plane light sources 35(3,3), 35(3,4), 35(4,3), 35(4,4) and , plane light sources 35(5,1), 35(5,2), 35(6,1), 35(6,2) and plane light sources 35(5,5), 35(5,6), 35( 6, 5) and 35 (6, 6) may be caused to emit white light, and the other planar light source 35 may be caused to emit blue light.

In the above embodiment, the CPU 81 detects the number of passengers waiting at the boarding/alighting position based on the image information from the camera 37 when the car 31 stops at the boarding/alighting position. Alternatively, for example, as shown in FIG. 12, the number of waiting passengers may be detected based on image information from a camera 38 that captures images of passengers waiting on the floor F where the car 31 stops. good. By using the camera 38 provided on each floor F, it is possible to adjust the set number of passengers according to the congestion situation of each floor.

In the above embodiment, the set number of passengers is set according to the number of passengers waiting at the boarding/alighting position. Alternatively, the set number of passengers may be set based on the number of passengers in the car 31 . In this case, the number of passengers in the car 31 can be specified based on the image information from the camera 37, the load of the car 31, and the like.

While several embodiments of the invention have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention.
