JP2000026039A - Crime prevension device of elevator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To preliminarily prevent a suspicious character from entering an elevator by invalidating the hall call for other floors against the register of the hall call for one floor, and invalidating the hall call register of all floors and the door closing at the same time when a load is detected by a load detecting device installed in a car. SOLUTION: The normal operation is effected when the night-time specified time zone is not judged by a night-time specified time zone detecting device 2, and the reference floor is judged by a reference floor detecting circuit 9 when the night-time specified time zone is judged. When the reference floor is judged, an in-car load detecting device 3 detects the in-car load. When the car load is detected, the hall call for other floors is invalidated assuming that a passenger is present in the car, and the car is in the waiting condition with its door open. When no car load is detected, the presence/absence of the hall call register is judged, and when not registered, the elevator is in the waiting condition at the reference floor. When registered, the hall call for other floors is invalidated. A passenger can be prevented from entering from other floors.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operating device, and more particularly to an elevator security device suitable for a multi-story elevator.

[0002]

2. Description of the Related Art An elevator car automatically opens a door after arriving at a service floor, and automatically closes a door after a lapse of a predetermined time. In addition, when the elevator is running, the room is closed, and this is abused, and there is a crime that acts to violate the passengers in the car. To prevent this, for example, as disclosed in Japanese Utility Model Laid-Open No. 51768/1981, each floor is stopped for a specific time period at night. That is, when the user gets on the car from the first floor and registers the car call button of the arbitrary floor, the vehicle is driven while stopping on each floor from the first floor to the arbitrary floor registered with the car call.

[0003]

However, when the above-mentioned stop operation on each floor is performed, it takes a long time to arrive at the destination floor. As a result, the driving efficiency is reduced, and passengers are irritated. In addition, in the stop operation at each floor, a door of a suspicious person in the hall is given a chance to get into the car by automatically opening and closing the door each time the vehicle arrives at each floor. Further, it is conceivable that a hall call is registered, and when the car arrives at the floor where the waiter is located, the car is shared with a suspicious person in the car. Therefore, there is a problem that it is difficult to perform the stop operation on each floor in the multi-floor elevator.

It is an object of the present invention to provide an elevator security device which maintains the security effect and shortens the operation time in view of the above-mentioned drawbacks.

[0005]

According to the present invention, it is an object of the present invention to provide a method for detecting a hall call on a certain floor, in which a hall call on another floor is invalidated. If detected, this is achieved by invalidating hall call registration on all floors and simultaneously disabling door closing.

That is, when a hall call or a car call on a certain floor is registered, the hall call or the car call on another floor is invalidated. In addition, while the load is detected on the car, the hall call on all floors is invalidated, and the door closing is invalidated at the same time, whereby an effect of preventing riding with a suspicious person is obtained.

An embodiment of the present invention shown in FIG. 1 shows a hall call / car call registration circuit and a hall call / car call permission switching circuit according to the present invention in an elevator operating device. This is an embodiment suitable for an elevator on the third floor. In this embodiment, a hall call / car call registration circuit, a nighttime specific time zone detection device 2, a car load detection device 3, and a reference floor detection circuit 9 for determining the switching condition of the hall call / car call permission switching circuit 5, and Normally open contact 4 for each floor hall call button entered by registering the hall call for each floor
a, 4b, 4c, each floor hall call button normally closed contact 6a, 6b, 6 which invalidates registration of hall calls on other floors at this time.
c, each floor car call button normally open contact 7a, 7b, 7c which is entered upon registration of each floor car call, and each floor car call button normally closed contact 8a, which invalidates the registration of a car call on another floor at this time.
8b and 8c.

FIG. 2 is a flowchart showing the processing performed by the hall call / car call registration circuit 1 and the hall call / car call permission switching circuit 5 in the embodiment shown in FIG. The operation of the embodiment shown in FIG. 1 will be described with reference to the flowchart shown in FIG. In order to register a hall call and a car call without having to ride a suspicious person in the car during a security operation, the following operation process is performed.

First, at step S1, the night specific time zone detecting device 2 determines the night specific time zone.
If it is not determined that it is the night specific time zone, the normal operation of step 2 is continued. Conversely, when the night specific time zone is detected, the reference floor detection circuit 9 determines the reference floor in step 3. Step 1 if it is not determined to be the reference floor
Jump to 1 and return to the reference floor. If it is determined that the floor is the reference floor, the in-car load detection device 3 detects the in-car load in step 4.

If the load in the car is detected in step 4, it is considered that a passenger is in the car, and the process of invalidating the hall call on the other floor is performed in step 12 and the door is opened. Become a stand-by to prevent sharing with other passengers. When the load in the car is not detected, the process jumps to step 5 for the first time, and the presence or absence of the hall call registration is determined.

If the hall call has not been registered, a standby state is set at the reference floor in step 9. If the hall call is registered, a process of invalidating the hall call on the other floor in step 6 is performed. This can prevent passengers from coming from other floors. afterwards,
If there is no car call registration in step 7, the floor is on standby. If there is a car call registration, the arrival at the service floor in step 8 is determined. If the passenger has not arrived at the service floor, the other floor hall call is invalidated because the passenger is in service.

When the vehicle arrives at the service floor, the in-car load is detected by the in-car load detecting device 3 in step 10 after the door is opened. If the load in the car is continuously detected even after the arrival at the service floor, it means that the passenger is left in the car, so that the other floor hall call in step 12 is invalidated, and the elevator is operated by waiting for the door to open. Absent. As a result, it is possible to prevent riding with other passengers.
When the load in the car is no longer detected and the door is closed, the process returns to the reference floor in step 11 for the first time to prepare for the next service. From the above flowchart, it is possible to safely service the passengers during the security operation without sharing with other passengers.

Although the above-described embodiment of the present invention has been described as applying the present invention to an elevator which services three floors, the present invention is also applicable to an elevator which services multiple floors. Can be applied.

[0016]

As described above in detail, according to the present invention, there is no halfway stop floor compared with the conventional floor stop operation, so that the service of the user can be improved and the user is suspicious. It is possible to prevent a rider from riding in advance and to obtain an effect on crime prevention.
