Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to an improvement of a device for crime prevention operation of an elevator car.

[Prior art]

In recent years, crimes occurring in elevator cars have been increasing, which has become a social problem. Therefore, a TV camera is installed in the car and is remotely monitored by a TV receiver. For example, ELEVATOR WORLD ELEVATOR WO

It is also shown in "CTV SECURITY".

However, this device has a difficulty in adoption due to the problem of privacy invasion and the need for a monitor at all times.
A spatial filter method has also been proposed in which a device for detecting light is provided on the ceiling of a car to detect human movement as a change in pulse, but there is a problem in the detection accuracy.

In addition to the above detection devices, the Building Standard Law obliges that the night car be forcibly stopped on each floor as a crime prevention function in terms of operation type. However, passengers feel extremely frustrated when driving on each floor, and there is a theory that psychologically it is safer to drive directly.

[Outline of Invention]

The present invention is to improve the above-mentioned inconvenience, and detects whether the number of passengers is two or more from the outputs of a plurality of detection elements arranged on the car floor, and detects their positions to grasp the abnormal movement, thereby preventing crime. An object of the present invention is to provide a crime prevention driving device for an elevator, which is capable of performing crime prevention driving by detecting an abnormality with high accuracy without violating privacy by switching to driving.

Example of Invention

An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows the overall configuration of this embodiment.

That is, by inputting the output of the passenger detection device (1) consisting of a plurality of detection elements arranged on the floor of the elevator car, the number of passengers and position detection means (2) determines whether the number of passengers is two and its position. Anomaly detection means (3)
Then, if it detects that there are two passengers and their position is biased to one side, or that the moving speed of the passengers is abnormal, it issues an abnormal signal to the elevator operation circuit (4) and forces the car to operate on each floor, etc. It is to switch to crime prevention driving.

2 to 5 show a concrete embodiment of FIG.

In the figure, (1) is a passenger detection device laid on the car floor (6), x
The coordinate detector (1A) and the y coordinate detector (1B) are placed on top of each other. The x- and y-coordinate detectors (1A) and (1B) are each composed of detector elements A arranged vertically and horizontally.
Each detection element A includes a substrate Aa, a front plate Ab installed in parallel with the substrate Aa, and a transparent insulating film Ac, which is adhered to the opposing surfaces thereof.
Ad and a spacing piece Ae made of a flexible insulating material interposed between the films Ac and Ad and holding an appropriate interval between them, and the film
It is composed of transparent electrodes Af and Ag provided on the facing surfaces of Ac and Ad. (7) and (8) are passenger's feet on the passenger detection device (1), and (9) is a control device which is composed of a micro computer and executes the means (2) and (3) of FIG. Processing device (below
(CPU) (9A), read-only memory (9B) that stores programs and fixed value data, readable and writable memory (9C) that temporarily stores data such as calculation results, and x coordinate detector (1A ) Input circuit (9D) that constitutes a converter for taking in the signal from each detection element A into the CPU (9A), and the signal from each detection element A of the y-coordinate detector (1B) to the CPU (9B). 9A) Input circuit (9E) that composes the converter for taking in, and CPU
Elevator operation circuit with the signal from (9A) as an abnormal signal
It is composed of a converter (9F) for outputting to (4).

Since the passenger detection device (1) is transparent, it may be laid as it is on the conventional tiled car floor (6). Also, if the car floor (6) is covered with Jiyutan, then the Jiyutan may be laid over the passenger detection device (6).

Next, the operation of this embodiment will be described.

When the passenger stands on the passenger detection device (1), their feet (7), (8)
Since the transparent electrodes Af and Ag of the detector element A of the x and y coordinate detectors (1A) and (1B) of the stepped portion are in contact with each other, the position is detected as the intersection of the x coordinate and the y coordinate. . For example, when the detection element A with hatching in FIG. 3 is pressed, it is detected as an intersection of x coordinate 6 and y coordinate 4. In this way, the position and the number of passengers are detected by the passenger detection device (1).

These x and y coordinate detection signals are taken into the control device (9), the position of the detection element A corresponding to the intersection of these coordinates is determined, and the passenger's foot is detected from the aggregated state of this position and its position. , It is determined whether or not there is an abnormality from the position and movement of the passenger. That is, in general, strangers usually stand apart from each other in the elevator car, and the car ride time is short, so that they do not move around. Therefore, on the contrary, two passengers are very close to each other,
When moving around in the car, it is considered that there is something abnormal and an abnormal signal is issued to switch to crime prevention operation.

The above will be described with reference to the flow chart of the operation of FIG.

Start the car in step (11). Passenger detection device in step (12)
It is determined whether there are two passengers from the x and y coordinate detection signals from (1). Step (13) if determined to be two
Use to determine if the two are far apart. If it is determined that the time is not far, it is determined in step (14) whether the time is short. If it is determined that the time is not short, step (15)
Sends an abnormal signal to the elevator operation circuit (4) and switches the car to crime prevention operation. For crime prevention operation, switch to forced stop operation on each floor to shorten boarding time and increase passengers' chances of exiting to the landing, or give a warning message such as "Please leave" in the car. .

If it is determined that there are two passengers in step (12), step (16)
Then, it is determined from the moving speeds of the above coordinates whether the moving speeds of both are abnormal. If it is determined that the moving speed is abnormal, the procedure (1
Switch to crime prevention driving in 5). If it is determined that the moving speed is not abnormal, step (13) is executed. Although it is determined in step (12) that there are not two passengers (one or three or more), the procedure (1
In step 3), it is determined that the two people are far from each other, or in step 14
If it is judged that the time when two people are close together is short,
Proceed to (17) and crime prevention operation will not be performed.

Further, the switching to the crime prevention driving may be limited to only at night.

[Effects of the Invention] As described above, in the present invention, a plurality of detection elements are arranged on the car floor of an elevator, and whether the number of passengers is two or not and their positions are detected from the X-coordinate and Y-coordinate detection signals. When the number of passengers is two and the position is biased to one side or the moving speed of the passengers is abnormal, an abnormal signal is issued and the car is switched to the crime prevention operation.

This will allow you to
In addition, it is possible to detect an abnormality with high accuracy and perform crime prevention operation.
