Further, for example, in Japanese Utility Model Laid-Open No. 11-11677, when a plurality of passengers are in the car at a specific time of the night, each floor is stopped so that the passengers can escape to the landing in an emergency. What you have done is shown.

[0004]

Among the above-mentioned conventional crime prevention driving devices for elevators, in the former one, when there is a person at the landing on the destination floor, the car is prevented from being stopped at that floor. Since it is a closed room so that no one else can ride in it, the security function is maintained when riding alone in the car, but when multiple people are riding in the car, due to the closed room inside the car,
On the contrary, there is a problem that criminal activity is likely to occur.

In the latter case, the operation is performed on each floor to prevent the car from being closed up. Therefore, the crime prevention function is maintained when a plurality of people ride on the car, but when one person rides on the car. Has the problem that other people are free to ride, and conversely criminal acts are likely to occur.

The present invention has been made in order to solve the above-mentioned problems, and a crime prevention operation device for an elevator, which is capable of performing a crime prevention operation suitable for both the number of people in a car and the number of people in the car. The purpose is to provide.

[0007]

A crime prevention operation apparatus for an elevator according to the present invention, when a specific button installed in a car is operated, commands a first crime prevention operation when one passenger is detected, When a plurality of passengers are detected, the second crime prevention driving is instructed.

[0008]

In the present invention, the crime prevention operation is switched between when the number of passengers in the car is one and when there are a plurality of passengers. Therefore, the operation mode is automatically selected.

The car 25 is supported on a car frame 28 by a vibration proof rubber 29, and the load detector 3 for detecting the deflection of the vibration proof rubber 29 is provided. 30 is an operation panel in the car, and a destination button (not shown)
The crime prevention button 2 is provided outside the.

Next, the operation of this embodiment will be described with reference to FIG. The program of this flowchart is
It is stored in the memory 15B of the microcomputer 15. First,
In step 41, it is determined whether or not the crime prevention operation switch 1 in the control room is on, and if it is on, the process proceeds to step 42. In step 42, it is further determined whether or not the crime prevention button 2 in the car 25 is on. If it is on, the process proceeds to step 43. On the other hand, if it is determined in step 41 that the crime prevention operation switch 1 is off, the process proceeds to step 44, and similarly to step 42, it is determined whether the crime prevention button 2 is on. If it is on, the process proceeds to step 43. If it is off, the routine proceeds to step 45, where normal operation is executed.

In step 43, the number of people is detected by the load detector 3, and in step 46 it is judged whether the number of people detected is one. As a result, if it is one person, the process proceeds to step 47 and the first crime prevention operation (for one person) is set. That is, basket 2
No. 5 does not respond to the hall call, only the car call is exclusively operated, and the hall position indicator 9 is turned off so that the hall 25 does not know the position of the car 25. Further, the crime prevention driving indicator light 10 is turned on to display that the crime prevention driving is being performed.

When the car call is stopped at the floor where the car call is registered in step 48, the waiting passenger detector 8 is operated in step 49,
In step 50, the presence or absence of waiting passengers is determined. If there is no passenger, the process proceeds to step 51, the doors 23 and 26 are opened, and the passenger is lowered. Then, in step 52, the crime prevention operation by the crime prevention button 2 is canceled. On the other hand, if there are waiting customers, step 5
Proceed to 3 and move to another floor without stopping the car 25.
Then, the process returns to step 49, and steps 49, 50, 5
Repeat 3 and move to a floor where there are no passengers, stop, and open the door.

On the other hand, when the security button 2 is off in step 42 or when the number of detected persons is two or more in step 46, the process proceeds to step 54 and the second crime prevention operation (for a plurality of people) is set. That is, the car 25 performs an operation of forcibly stopping at each floor and opening the door 26. And step 55
Then, it is judged whether the current stop floor is the stop floor due to the last car call. If it is due to the last car call, the process proceeds to step 52, and if the crime prevention operation by the crime prevention button 2 is being executed, it is released. On the other hand, when the stop floor is not due to the final car call, the process returns to step 43, the number of people in the car is detected, and the process proceeds to step 47 or step 54 to repeat until the final car call stop floor is reached.

Embodiment 2. In the first embodiment, the waiting passenger detector 8 is installed in the car door 26 to reduce the number of the waiting passenger detectors 8. However, when the window glass 24 is not used for the hall door 23, The waiting passenger detector 8 may be installed on the hall 21 side. In this case, if the waiting passenger detector 8 is used not only for crime prevention driving but also for measuring the number of waiting passengers, the congestion degree of the hall 21 can be measured, and thus it is possible to improve driving efficiency as well as crime prevention. ..

Example 3. Further, although the crime prevention operation starting means by the passenger is the crime prevention button 2 in the car 25, it may be carried out by a personal identification number or the like using the operation button. Further, as the means for simultaneously activating the crime prevention operation for a plurality of people in the control room or the like, the operation of the crime prevention operation switch 1 by the administrator is employed, but this may be a crime prevention operation activation means for a plurality of people by setting the time limit. Further, the effective time for switching to the crime prevention operation may be effective only during nighttime or the like in order to prevent a decrease in operating efficiency.
