Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, as a means of preventing crimes and accidents in elevators, it has been common practice in apartments and condominiums to stop the elevators at night. In addition, if a crime or accident is about to occur, we will install a device that detects when too many buttons in the car are pressed at once, or a device that detects screams or abnormal noises in the car, and use these devices. Some methods have been proposed, such as stopping the elevator at the nearest floor or reporting to the manager's office or other external location to prevent any serious problems from occurring.However, in the conventional method, for example, In the first example, when a crime occurs, it is necessary to use one's own knife to escape unless there are other people in the hall, and during normal times when a crime is not occurring, the elevator will be started and stopped needlessly, which is unreasonable. be.

Also, the second. In the third example, when a crime occurs, the victim is forced to press a button or make a scream.

Therefore, if a person is involved in a crime in an instant, they may not be able to perform the above-mentioned actions because they do not have enough time, or they may not have the time to scream. In such cases, crimes and accidents cannot be prevented by the above-mentioned devices alone.

The present invention was made in order to improve the above-mentioned drawbacks of the prior art, and when involved in a crime, the crime in the elevator can be prevented by utilizing the natural movements of the victim and the perpetrator. Furthermore, the purpose is to prevent accidents caused by pranks and prevent them from becoming serious.In other words, when a crime occurs inside a car, the victim instinctively moves away from the car to maintain distance from the perpetrator. When this happens, it is normal for the car to run around and collide strongly with the cab panel. Furthermore, when the assailant and the victim become tangled, it is very common for the perpetrator to hit the car panel or fall and collide strongly with the floor.

Furthermore, when a child runs around inside the car due to mischief, etc., it is common for the car to collide strongly with the car panel or jump, causing a strong impact to be applied to the floor.

The present invention has been made with attention to the above point, and since a device for detecting this impact is installed on the car panel or the floor of the car, the victim does not need to take any conscious actions or movements, and the impact can be detected unconsciously. Using the extremely natural movement of the elevator, it detects crimes inside the elevator car, and also detects mischief that could lead to an accident, and stops the elevator at the nearest floor or sends a report to the outside, such as the manager's room. It becomes possible to more reliably prevent crimes and accidents and prevent them from becoming serious.

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram showing the overall configuration of the present invention.
~1C is an impact detection device installed in the car and emits an output according to the strength of the applied impact, and 2 is an impact determination device that determines whether the input impact is an abnormal impact. If it is an impact, an output signal 2a is issued to the safety device @10'. The safety device 10 may be, for example, the top floor stop device W 3 or the external notification device 4, but if it affects the safety of passengers, it will notify that a crime has occurred in the car. Any type of display device, alarm device, device for switching to stop operation on each floor, or a combination of these may be used.

FIG. 2 is a diagram showing how the impact detection devices 1a to 1c are installed, and 20 is the elevator jaw and 30 is the main lobe. This example shows that two impact detection devices are attached to the side of the car 20 and one is attached to the floor.

FIG. 3 shows an example of the circuit of the impact determination device 2.
8c is a signal from the impact detection device 1a"-1c, 5 is an adder that adds the input signals and outputs the value as signal 5a, 6 is a reference value generator that emits a reference signal 6a, and 7 is a reference value generator. This is a comparator that compares the magnitude of the signal from adder 6 with the signal from adder 5 and outputs an output when the magnitude is greater than a reference value.The impact detection device that outputs an output depending on the strength of the impact is a known shock detection device. Since this is a simple matter, the explanation will be omitted here.

The operation of the above configuration will be explained next.
Suppose that an abnormality occurs inside the car and the passenger strongly hits the side of the car 20. At this time, the impact detection devices 1a and 1c attached to the side of the car 20 output an output 8a corresponding to the degree of the impact. , 8b, and the impact detection device 1C attached to the floor also emits an output 8C corresponding to the strength of the impact applied to the floor. The 0 adder 5 adds the output signals 8a to 8C from those impact detection devices. is calculated and outputs the value as a signal 5a.

The comparator 7 compares the input signal 5a and the reference signal 6a, and when the input signal 5a is larger, outputs the output signal 2a. The nearest floor stop notification device 4 stops the elevator at the nearest floor based on the output signal 2 from the impact determination device 2, and notifies the outside of the abnormality.

In the above embodiment, the determination was made based on the sum of the output signals from the impact detection device, but of course the determination may be made based on the maximum value among them.

In addition, it goes without saying that the mounting position and number of impact detection devices may be arbitrary, and the impact detection device and impact judgment device may be integrated to generate an output only when an impact exceeding a predetermined value is applied. good.

As described above, according to the present invention, it is possible to exhibit a great effect in preventing crimes and mischief in elevator cars.
