Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an elevator security operation device for preventing crimes in the elevator car.

[Prior art]

Elevators in buildings are places where malicious crimes such as theft and sexual crimes are likely to occur. This is because there is no one in the elevator hall and the surrounding area faces the walls, even though the car has glass windows on the door and side walls, making it possible to see the inside of the car from the outside. This happens because if there are many elevators in a shared elevator group, the elevator is a hidden space.

Conventionally, in order to rescue passengers in an elevator from these types of crimes, when a passenger shouts loudly, it is recognized as an abnormal sound by voice recognition, or when a rapid movement of a passenger in the car is detected, the elevator Various proposals have been made to encourage crime prevention driving. However, these automatic detection devices are likely to over-recognize casual movements made by a passenger, and may misidentify an ordinary passenger as a culprit, or misidentify a minor disturbance as a crime, resulting in unexpected damage to passengers. may be given.

Considering these shortcomings of elevator crime prevention automatic detection devices, what is required as a means of detecting crimes or criminals inside the elevator car is to correctly determine whether a crime has occurred or not, and whether it is an ordinary passenger or a criminal, based on the situation at that time. However, it is possible to leave it to the victim or other passengers to switch to crime-prevention driving if necessary, and in addition, the above operations can be performed quickly and accurately.

[Summary of the invention]

This invention has been made in view of the above-mentioned points, and improves the above-mentioned defects by providing a crime prevention driving command device in the first landing and the car, and only when the crime prevention driving command device meets a predetermined condition, the corner door is opened. In addition to extremely reducing the chances of the criminal getting into the car, the door can be opened for a predetermined period of time even if the door is closed as soon as the passenger and the criminal have boarded the car, making it easier for passengers to escape from inside the car. The purpose of the present invention is to provide a crime prevention operation device for an elevator that can be operated in a 17-day manner.

In addition, when the crime prevention driving command device is activated, one passenger in the car
In addition to determining whether the car is a person and opening/closing the car door, the system also issues crime prevention driving instructions such as not responding to calls from the first floor on the way and driving directly to the destination floor. can also be easily implemented.

It is clear that the same effect can be obtained by using a photoelectric device provided at the entrance of the car, a personal sensor, or a plurality of buttons to perform the function of instructing the crime prevention operation and the door opening/closing function.

Furthermore, in the above embodiment, a waiting passenger at the first landing presses the landing crime prevention operation command button (1), then presses the in-car crime prevention door opening button (9), reverses the opening of the door, and then waits with the voice open. However, it is also possible to easily cancel the hall crime prevention driving command after a certain period of time, or automatically or forcibly, and return to the normal door opening/closing operation.

By configuring in this way, the above example of real power can be obtained.

A security driving command device is installed in the landing and in the car.9 When the security driving command device in the landing and in the car is activated, it determines that there is only one passenger inside the corner and issues a security driving command, and the door is closed. The car door can be opened and closed freely so that the car door can be opened and closed, and at the same time, the opportunity for other passengers to get on the car after the car door is reduced, and even if other passengers get on the car, they can easily escape.

Even if the door is closed with both the passenger and the criminal inside the car, the door can be opened for a predetermined period of time, allowing the passenger to easily escape from inside the car.

Additionally, if only one of the crime prevention operation command relays in either the 9 landing or the car operates, it is possible to increase the crime prevention effect at the 1 landing by keeping one door open or 9 opening and closing the door normally. Of course.

It is also possible to prevent a decline in elevator operating efficiency due to abuse of crime prevention driving.

Furthermore, the second security driving command device may be automatically activated at a predetermined time period.

〔Effect of the invention〕

As described above, this invention includes a first security driving command device in the car, a second crime prevention driving command device in the landing, and a system that opens a closed door when activation signals from these devices are issued. Equipped with a door-opening mechanism that functions as an elevator, it is possible to prevent crimes using elevators, and
This has the effect of preventing a decline in elevator operating efficiency due to abuse of crime prevention operation.
