Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a crime prevention device equipped with a crime prevention driving means that ignores a landing call from an intermediate floor and goes straight to the destination floor by pressing a crime prevention button. This invention relates to an elevator with a device.

[Technical background of the invention and its problems]

As a crime prevention measure in elevators, a method has been proposed in which the elevator is switched to crime prevention operation by pressing the crime prevention button at the landing on the standard floor, and even if there is a hall call from an intermediate floor, the elevator will ignore the call and drive straight to the floor where the car call is registered. has been done. Although this method can prevent criminals from boarding the train midway, it does not take into consideration boarding of 2 Å or more on the standard floor, and there is a risk that criminals may get mixed up in the boarding.

Furthermore, conventional elevators are insufficient as a crime prevention measure because the elevator arrives at the floor and opens the door regardless of whether or not a criminal is ambushing the floor where the car is registered.

(Object of the Invention) The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide an elevator equipped with a security device that takes safer crime prevention measures.

[Summary of the invention]

In order to achieve the above object, the present invention provides a detection means for detecting the number of passengers in a car, a discrimination means for discriminating whether the number of passengers detected by the detection means is one or two or more, and a security driving system. In this case, if the number of passengers according to the above-mentioned discrimination means is 1, the car call registration will start immediately, and if the number of passengers according to the above-mentioned discrimination means is 2 or more despite crime prevention operation, the operation will start even if there is a car call registration. The first feature is that a means for sounding an alarm without starting with the door in the state is provided.

Furthermore, the present invention includes a detection means for detecting the presence or absence of a waiting passenger at a landing on each floor other than the reference floor, and when the detection means outputs a detection result that there is a waiting passenger on the floor of the car call registration, the car call registration is performed. The second feature is that the vehicle is provided with a means for forcing the passenger to land on the nearest floor where there are no waiting passengers without landing on the floor.

When forcibly landing on a floor other than the floor registered as a car call,
It is preferable to provide a notification means for informing passengers in the car of the landing floor.

[Embodiments of the invention]

FIG. 1 shows an embodiment of the present invention.

When the security button 11 provided at the landing of the standard floor, which is normally set to the 1st floor, is pressed, the security operation activation device 12 activates the elevator from the standard floor to the floor for which the car call is registered on the car operation panel 15. Switched to direct operation. At this time, hall calls made on floors other than the standard floor remain registered and are ignored until the crime prevention operation ends, and the hall calls are not answered, and normal operation returns only after the crime prevention operation ends. A security sensor 13 is provided inside the car to detect the number of passengers entering the car during security operation. As this security sensor 13, for example, a pyroelectric optical sensor can be used. This pyroelectric optical sensor is a sensor that outputs an electrical output according to the rate of change of heat when it senses heat rays. The presence of passengers can be confirmed by turning on and off the infrared light.

FIG. 2 shows a device for counting the number of passengers in a car. A human body 31 obtained by scanning the inside of the cage by rotating the above-mentioned pyroelectric optical sensor itself or a scanning mirror.
The infrared rays from the
The number of passengers in the car can be known by inputting the information to the counter 36 via the number 5. In order to ensure safety in detecting the number of passengers, multiple sets of pyroelectric photodetectors 34 may be arranged to detect from multiple directions with different angles, and the maximum value or maximum frequency value among the detected values may be used. It is better to do so.

When the in-car security sensor 13 detects the number of passengers in this way and the detection result is one passenger, a start permission signal is sent to the car operation panel 15, and car operation 5! In accordance with the car call registration operation performed on a15, direct operation begins via the gate circuit 21 to the destination floor registered in the registration circuit 22. However, if the security sensor 13 detects two or more people, a signal indicating that the start is not permitted is sent to the car operation 115.
This causes the car to stop with its door open, and an alarm, such as a buzzer or bell, to sound to notify the surrounding area. In addition, if two or more acquaintances are boarding,
In the first place, there is no need to press the security button (therefore, it does not enter security driving, so the above problem does not occur.

Each landing other than the standard floor is provided with a landing security sensor 14 that is activated during security operation and monitors whether there are waiting passengers on the floor. In other words, the hall crime prevention sensor 14 is a sensor that detects whether or not there is a person waiting for passengers who boarded from the standard floor to get off during crime prevention operation.

When the hall crime prevention sensor 14 detects that there is a waiting passenger, a comparison device 16 determines the logical product of the detection result of "single passenger" by the in-car crime prevention sensor 13, and stores it in a temporary holding device 17. When the stored content, that is, the floor where the waiting passenger is located, is carried out on the car operation panel 15 and the floor of the car call registration matches, it is dangerous to get off at that floor via the control device 18. When it is determined that this is the case, the vehicle stops stopping at that floor, does not stop, and stops at the nearest floor where there are no waiting passengers (the floor closest to the destination floor among the floors where there are no waiting passengers).
is selected by the selection circuit 19, registered in the registration circuit 22 via the command device 20 and gate circuit 21, and forced to land there. In this case, passengers in the car will be informed of the reason for not being able to stop at their destination floor through audio, visual display, or both.

In addition, if the landing security sensors 14 on all floors other than the destination floor based on the car call registration have detected that there are waiting passengers, the door may remain stopped at the reference floor, or the door may not be opened even if it has started. The car is returned to the standard floor without any problems, and the passengers in the car are informed of the reason. If there is no waiting passenger on the floor of the car call registration done in the car, the landing security sensor 14
If it is determined to be safe, the train will operate directly from the standard floor and land on the target floor, then open the doors and let passengers get off, completing a series of crime-prevention operations and transitioning to normal operation. .

〔Effect of the invention〕

As described above, according to the present invention, a single passenger may be locked in a car alone with a criminal, or a passenger may be stopped on the landing floor even though a criminal is waiting there. It is possible to provide an elevator with a crime prevention device that is useful in preventing the occurrence of crime without opening the door.
