Description

Anomaly Detection and Alarm Device for Elevators {ABNORMALITY SENSING OF THE INSIDE OF AN ELEVATOR AND ALARM DEVICE OF THE ELEVATOR}

The present invention relates to an internal abnormality detecting and alarming device of an elevator. Specifically, a high-sensitivity microphone and a G-sensor are configured inside an elevator to detect a voice through a high-sensitivity microphone and a vibration of up, down, left, and right through the G sensor at the same time. Security guards and administrators of elevator occupants by recognizing the abnormal situation of the elevator and by transmitting the video information on the floor currently being operated by the auxiliary camera to the manager in a PIP manner in addition to the main camera which photographs the interior of the elevator. It is related to the internal abnormality detection and alarm device of the elevator to prevent the accident to be able to respond quickly to the manager when the accident occurs, or to complete the alarm for all safety accidents occurring in the elevator.

In general, elevators are longitudinal transportation means, ranging from small buildings to skyscrapers of several tens of floors depending on the purpose of the building, and functioning according to the purpose of the building. In addition, since these elevators operate for all age groups, from infants to the elderly, it should be easy for anyone to use such as comfort of platform and platform, operability and visibility of operation indicator.

On the other hand, in recent years, the crime is continuously increasing in the above-mentioned elevator, many of the crimes using the elevator occurs after the door is closed with only the victim and a few criminals ride on the elevator.

Accordingly, in order to prevent the crime as described above, in order to improve the safety of passengers in the elevator, a closed circuit TV (CCTV) and a certain portion of the elevator door are installed in the elevator with transparent windows to check the inside of the elevator from the outside. Security windows are also provided to allow for this.

In addition, a service function for protecting passengers may be provided according to each floor forced stop driving function and crime prevention driving function which is an elevator driving method, and the forced stop driving function is performed by turning on a corresponding switch provided in an elevator by a passenger. All floors between the departure floor and the destination floor are registered so that each floor stops at each floor and travels to the destination floor. The crime prevention driving function allows the user to press the security button attached to the platform to call the platform even if an elevator call occurs. By disregarding driving to the destination floor, or by calling a platform that nobody is riding on, the passengers can switch to the exclusive driving and drive to the destination floor.

However, in the case of monitoring the interior of the elevator by CCTV as described above, the person who monitors the image data captured by the CCTV through a predetermined monitor must continue to monitor it, so if the shift or unavoidable work place should be empty If a case occurs, there was a problem that can not effectively cope with the crime.

In addition, when the forced stop operation function is provided, the elevator can be stopped on each floor to prevent crimes that may occur when passengers and criminals are traveling on the elevator, while restraining the criminals who invade from the platform. On the contrary, when the crime prevention function is provided, the occupant can prevent an intruder from entering the platform, but there is another problem that can cause injuries when the passenger is unavoidably in the elevator. .

In addition, in recent years, due to the aging of society, the number of elderly people who use elevators has increased, and the use of elevators by the elderly is much higher than in the past. There was a problem that can not effectively cope with disease accidents that can occur within.

Thus, on July 15, 1999, Patent Application No. 10-1999-0028611 (control method and device of elevator by voice / image data) was proposed,

The method may include detecting whether voice data identical to voice data stored in a predetermined level or more voice or RAM is generated from a passenger in a normal operating elevator,

When the voice or voice data is generated above the predetermined level, the elevator call command generated from the platform is canceled and the call operation for driving to the lobby floor is registered, and the return operation is performed to the lobby floor according to the call registration. Steps,

When the elevator arrives at the lobby floor, outputting voice information through a speaker provided at a predetermined position of the lobby floor, and waiting for the elevator door to be closed;

And after the standby state, performing normal driving according to the switching of the operation mode of the elevator.

Detecting image information of the passenger by a predetermined camera provided in the elevator while the elevator is operating normally, and determining whether a call operation to the elevator has occurred;

When the call operation occurs, normal operation according to the call operation is performed; when the call operation does not occur, starting a counter for a predetermined time together with the image information detection operation;

If the movement of the passenger is not detected for a predetermined time from the counter start operation, the elevator call command generated from the platform is canceled, and a call operation for driving to the lobby floor is registered, and according to the call registration. Performing a return operation to the lobby floor;

When the elevator arrives at the lobby floor, outputting an alarm through an alarm light provided at a predetermined position of the lobby floor and waiting for the elevator door to be opened;

After the standby state, it was configured to include the step of performing a normal operation in accordance with the switching of the operation mode of the elevator.

In addition, Patent Application No. 20-1999-0024946 dated November 15, 1999 (elevator's image surveillance system) has been proposed,

This is provided with a surveillance camera inside the cage on which the passenger is boarded, and the image signal photographed by the surveillance camera is transmitted to the display apparatus installed in each floor through the transmission device and the repeater and displayed. Accordingly, the situation inside the cage can be inquired by an unspecified passenger who can wait on each floor.

Then, the predetermined information is transmitted to the display device that can be installed inside the cage through the repeater, and thus information useful to the passengers can be displayed on the display device.

However, according to the conventional control method and apparatus of the above-mentioned voice and image data, the inside of the elevator is monitored by the camera and the voice so that the situation can be known from the outside. Of course, there was a drawback that the phenomenon of exciting people in the situation of forced elevator operation may occur.

The present invention is to solve the conventional problems as described above, by configuring a high-sensitivity microphone and G sensor in the elevator inside the elevator while sensing the vibration of the voice through the high sensitivity microphone and up and down, left and right at the same time in the elevator The safety status of the elevator occupants can be sent to the security guards and the managers by recognizing the abnormal situation and transmitting the image information on the floor currently being operated by the auxiliary camera to the manager in a PIP manner in addition to the main camera photographing the interior of the elevator. Its purpose is to provide an elevator internal abnormality detection and alarm system that can be delivered to the alarm so that the manager can respond promptly to the accident or the alarm can be completely prevented for all safety accidents occurring in the elevator.
