Abstract

PURPOSE:To positively catch a thief on the run by directly traveling, an elevator whose door is in opened state on the floor where a theft alarm detecting device operates, to a specific floor after the elevator door is closed and controlling a door control switch for the specific floor by a switch installed in a guard station or at a getting-on field on the specific floor. CONSTITUTION:When an all-time opened contact point 4a for alarming theft on the fourth floor is operated at a guard station on the second floor, if an elevator door is opened on the fourth floor, an alarm device 15 operates, and the compulsory return of an elevator from the fourth floor to the second floor is informed. After the lapse of an interference time, the door is closed, and all the registered call for a cage is deleted at all, and answer is not generated for the call at a getting-on field. At this time, an all-time closed contact point 14b is energized, and elevator passage is opened, and the cage starts the DOWN traveling. When the cage travels to the guard station floor, the all-time opened contact point 12a for detecting the cage position on the guard station floor is closed, and the elevator stops on the guard floor. At this time, the door is controlled only by the operation of a door opening instruction switch.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator operating device that can actively capture a criminal who commits a crime indoors and attempts to escape in an elevator.

[Prior Art] Conventionally, as an example of this type of elevator operating system, as shown in Japanese Utility Model Publication No. 58-20611,
When a crime occurs indoors, a switch installed on each floor is operated to artificially disable the car call or hall call elevator service on the floor where the crime occurred, cutting off the criminal's escape route and allowing him or her to escape. There are things that can be done to prevent this.

As another example, as shown in Japanese Patent Application Laid-Open No. 59-53381, an abnormality detection device is installed inside the car, and when this detection device detects an abnormality, the car is automatically moved to a specific floor. There is one that allows you to go straight.

[Problems to be Solved by the Invention] However, in the former method, which disables the elevator service on the floor where the crime occurred to cut off the criminal's escape route, the staff can operate the switch provided on each floor. It takes time from the time a crime occurs until service is cut on the relevant floor, as it is operated manually after confirming the crime prevention alarm.
There is a risk of accidentally operating a floor other than the one in question, and criminals can easily see that their escape route has been cut off due to a service cut, which poses problems such as adding extra stimulus to criminals.

In addition, the latter method, which automatically directs the car directly to a specific floor by detecting an abnormality inside the car, cannot detect crimes that occur indoors (outside the car), so if a criminal flees from inside the car, the crime cannot be detected. If the driver got into the vehicle without incident, the vehicle would be driven normally, which would end up helping the vehicle escape.

The present invention has been made in order to solve the above-mentioned problems, and aims to provide an elevator operating device that can actively capture criminals who commit crimes indoors and try to escape by elevator. purpose.

[Means for Solving the Problems] An elevator operation device according to the present invention includes a crime prevention alarm detection device that detects that a crime prevention alarm device installed on each floor indoors is activated, and a crime prevention alarm detection device that detects when the crime prevention alarm detection device is activated. This device is equipped with a forced operation device that causes an elevator whose door opens on a certain floor to go straight to a specific floor after the door is closed, and a door control device that controls the door control of a specific floor by a switch installed in a security room or a specific floor landing. .

[Function] In the present invention, when the crime prevention alarm detection device detects that the crime prevention alarm device has operated, the forced operation device divides the elevator service into the service for the general floor and the service for the crime floor. To ensure safety, check the use of elevators from crime floors, and direct elevators whose doors open on crime floors to specific floors after closing. When the elevator car returns to a specific floor, the door will not open unless an external switch that controls the door control device is operated, and the criminal can be captured in the car and prevented from escaping.

[Example] Hereinafter, an elevator operating system according to the present invention will be described based on an example shown in FIGS. 1 to 3. In the figure, (l
a), (2a), (3a), and (4a) are the constant contact points of the crime prevention alarm devices (for example, intrusion detection sensors, etc.) corresponding to xlW, 2nd floor, 3rd floor, and 4th floor, respectively, when a crime occurs. Only the contacts corresponding to the floors that have been closed will close.

If the door comes into contact with a person or object while it is closed, it will operate and open. (21a) is the normally open contact of the running relay that is energized while the elevator is running, (22) is the normally closed contact of the door opening command switch installed on the security floor, and (23) is the normally closed contact of the door opening command switch installed on the security floor. This is the normally closed contact of the reset button.

Next, the operation of the apparatus of this embodiment having the above-described configuration will be explained. In this operation description, an example will be described in which the second floor is a security floor and the normally open contact (4a) for the security alarm on the fourth floor is activated. Now, when the elevator door opens on the 4th floor, the normally closed contact (5b) is closed, and the normally closed contact (4a) on the 4th floor is closed, so (.+) (4a) - (14a)
