Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a display device that displays information on a painter in an elevator on a display device.

(Prior Art) FIG. 4 shows the appearance of a conventional elevator ball. Rising near the elevator entrance on each floor,
Alternatively, a push button 1 for instructing the lowering is provided. Then, when a passenger using the elevator presses this push button 1 to instruct ascending or descending, the elevator that will arrive earliest among the plurality of elevators is searched, and the corresponding hall lantern 2 flashes.

This allows passengers to know which elevator to use.

However, for example, office elevators are often used by a large number of people at specific times, such as during morning commuting hours, and the elevators are often full.

For this reason, even if the passengers waited at the entrance of the elevator where the hall lantern 2 was flashing, they were sometimes irritated because the elevator they arrived at was full and they could not board the elevator.

In order to solve this drawback, approximately 65 [k (l
] is known, in which the number of people who can ride the elevator is calculated, and this number is displayed in advance on the number of people indicator 3 before the elevator arrives, thereby informing the waiting customers in advance.

However, the number of people calculated as approximately 65 [kN per person] is an approximate number, and may differ significantly from the number of people who can actually ride. In addition, when transporting lightweight cargo in an elevator, there may be enough space for the loading foil, but there may not be enough space inside the elevator, and the number of people displayed on the people indicator 3 may not necessarily be accurate. , there was a problem of unreliability.

(Problem to be Solved by the Invention) As described above, conventionally, it was not possible to know the congestion situation inside the elevator until it arrived, and even when the IC% number of people indicator light 3 was provided, this display Because the number of passengers was not always accurate, there was a problem in that passengers could feel irritated or anxious while waiting for the elevator.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a camera that is installed at an appropriate location in each of a plurality of elevators and that images the situation inside the elevator. The present invention is characterized in that it includes a display device that is provided in each elevator hall and displays video information captured by each of the cameras in a switchable manner using a selection switch.

(Function) In the elevator congestion status display device according to the present invention, the situation inside the elevator is captured by a camera installed inside the elevator, and the obtained video information is displayed on a display device installed on each floor. So,
Passengers can learn about the situation inside the elevator before the elevator arrives.

Therefore, passengers no longer feel irritated or anxious while waiting for an elevator.

(Example) FIG. 1 is a block diagram showing an embodiment of the present invention.

As shown, in this embodiment there are three elevators 48-4.
Hall lanterns 2a to 2C are installed at the entrances and exits of each floor to display the arriving elevator.

Cameras 5a to 5c are attached to the ceiling of each elevator 48 to 4c to take images of the internal situation. In addition, the locations for picking up cameras 5a to 5c are elevators 48 to 4c.
Since the entire interior of the vehicle can be imaged, an inconspicuous location on the ceiling is preferred in order to protect the privacy of passengers. Furthermore, load detection devices 68 to 6C are attached to the floors of the elevators 4a to 4C to detect the weight inside.

Each camera 58 to 5c and each load detection device 16
a to 6C are connected to a control panel 7, and this control panel 7 is connected to a display device 8.

The display device 8 is provided at the entrance/exit of the elevators 48 to 4C on each floor, and includes push buttons 1 for instructing the elevators 4a to 4C to go up and down, and a video displaying video information for the elevators 48 to 4c given from the control panel 7. It consists of a panel 9 and a selection button 10 for switching the video information displayed on the video panel 9.

FIG. 2 is a block diagram showing the internal functions of the control panel 7. As shown in FIG.

As shown in the figure, the control 17 is connected to each elevator 4a.
~4C load detection device ff6a~5c and camera 58~
Information is taken in from 5C, and pushbuttons 1. and an input unit 11 that takes in information given from the selection button 10, an arithmetic processing unit 12 that generates information to be displayed on the video panel 9 from each of these data, and an output unit 13 that outputs this display information to the video panel 9. It is configured.

FIG. 3 is a flowchart showing the processing procedure inside the arithmetic processing section 12, and the operation of this embodiment will be explained with reference to the flowchart.

Now, if the passenger presses, for example, pushbutton 1 in the up direction (YES in step STI), the elevator that will arrive at the called floor earliest in the up direction is searched for among the elevators 48 to 4C (step 5T2).

If the elevator 4a is found, the up lamp of the hall lantern 2a corresponding to the elevator 4a will blink. Also, from the difference between the maximum loading weight of the elevator 4a and the weight detected by the load detection device 6a, 1
The number of people who can ride is calculated as approximately 65 [k(+]) per person (step 5T3) and displayed on the video panel 9.

At the same time, the image information inside the elevator 4a conveyed by the camera 5a is displayed on the image panel 9 (step 5T4).

The passengers judge whether all the waiting passengers can ride the elevator 4a based on the video information inside the elevator 4a displayed on the video panel 9 and the number of people who can ride. Then, if you cannot ride, press the selection button 10 (YES in step ST5), and if you can ride, wait without pressing the selection button 10 (No in step ST5).

When selection button 10 is pressed (YES in step ST5)
), the information in the next arriving elevator (temporarily 4b) is displayed on the video panel 9 according to steps ST2 to ST4. If it is not possible to ride this elevator 4b, the user presses the selection button 10 again to obtain information on the next elevator (tentatively 40) to arrive.

If selection button 10 is not pressed (NO in step ST5)
), when the elevators (4a to 4C) arrive (YES in step ST6), the screen is cleared (step 5T7).

The above operations are then repeated.

In this way, in this embodiment, before the elevator arrives, passengers can confirm the number of people who can ride the elevator and the video information inside the elevator. Therefore, it is possible to determine in advance and with certainty whether or not you can board the arriving elevator.
Passengers no longer feel irritated or anxious while waiting for an elevator.

Furthermore, since the situation inside the elevator is displayed on an external display device, it becomes useful for security monitoring.

[Effects of the Invention] As explained above, according to the present invention, images captured by cameras installed at appropriate locations in the elevator are displayed on the display device installed in the elevator hall of each floor, so that passengers can before the arrival of
You can know the internal situation of the elevator. For this reason,
If a passenger cannot board the elevator, such as when the elevator is full or loaded with luggage, etc., this will be immediately known, so waiting passengers will not be irritated.
The effect is that you no longer feel anxious.
