Description

EMERGENCY MONITORING SYSTEM FOR ELEVATORS}

The present invention relates to an emergency situation monitoring system, and more specifically, analyzes the number of passengers inside the elevator car through images captured by a camera installed inside the elevator car, and monitors each surveillance mode according to the number of passengers. is set, and relates to an emergency situation monitoring system for elevators that determines emergency or dangerous situations for passengers and selectively sends notification messages to terminals for fire departments or investigative agencies to enable prompt action.

An elevator is a transportation device that is installed inside a building and receives power to quickly move people or cargo from a low floor to a high floor or from a high floor to a low floor. As modern industrial technology develops, high-rise buildings begin to emerge, and elevators have also become an essential means of transportation, developing into a means of providing convenient services to people traveling inside elevators.

Generally, a person using an elevator presses the call switch of the elevator car installed on the side of the elevator door, moves the elevator car to the floor where the person who wants to use the elevator car is located, then gets on and moves to the desired floor. Here, there is a button section inside the elevator car that allows you to select the floor you want to move to.

Additionally, an emergency call button is installed so that people riding inside the elevator car can request help from management located outside the building if they become trapped inside the elevator car due to a malfunction of the elevator car. However, if a person in an elevator car collapses due to illness or is threatened by other passengers, they cannot press the emergency call button and thus cannot request help from management.

To solve the above problems, a surveillance camera was installed to film the interior of the elevator car in real time and provide the captured images to the management in real time. However, in the case of surveillance cameras, the situation inside the elevator car is captured in real time and the video is only provided to the management, so if an emergency situation occurs inside the elevator car, the emergency situation cannot be recognized unless the manager in the management department monitors the captured video. There is a problem that it cannot be done.

For example, if a person riding inside an elevator car is threatened by another person riding on the same floor or a different floor, a situation may arise in which the person cannot press the emergency call button because he or she is protecting his or her body from the threat. In the above situation, if the manager in the management department monitors the monitor in real time and recognizes the dangerous situation, he or she can provide help to the person in danger. However, if the manager in the management department is not aware of the dangerous situation, the person on board can provide help. You will not receive it.

Moreover, if the manager does not recognize the dangerous situation and the occupants cannot receive help, the occupants must escape the dangerous situation themselves. At this time, the elevator car moves to the selected floor. In other words, you can escape a dangerous situation by pressing the next floor of the floor you are currently moving to, stopping the elevator car, and then getting off the elevator car when the elevator car stops and the door opens. However, while protecting oneself from a dangerous situation, it is difficult for the occupants to escape the dangerous situation on their own due to the difficulty in pressing the button installed inside the elevator car.

In addition, if a person inside the elevator car falls inside the elevator car due to illness while the elevator car is in motion, the manager cannot provide direct help even if the manager recognizes it through the management monitor, so the fire department must be contacted separately. must be taken In other words, it becomes impossible to quickly provide help to a person who has collapsed due to disease.

Moreover, even when a rescuer from a fire department arrives at the location where the elevator car is installed, the elevator car has been moved to the floor selected before the person who collapsed due to illness collapsed, and the rescuer moves directly to the floor where the elevator car is located or moves the elevator car to the floor where the elevator car is located. Since the patient must be moved to this waiting floor, the time it takes to take direct action on a person who has collapsed due to illness may be longer, creating a more dangerous situation.

The purpose of the present invention, which was devised to solve the above problems, is to analyze and determine the situation occurring inside the elevator car, and when an emergency or dangerous situation occurs, to notify the remote management of each situation so that the manager can do so in real time. It recognizes the occurrence of an emergency or dangerous situation even without monitoring, and provides real-time information on emergency or problem situations to fire departments or investigative agencies to provide prompt assistance to people inside the elevator car.

It is done including.

As shown in FIG. 1, the elevator car 100 is provided with a door 110 that opens and closes to allow a person P to board, and moves up and down. At this time, the inside of the elevator car 100 is provided with a button unit (not shown) that selects the floor to which the person on board (P) wants to move, and the input signal from the button unit is transmitted to the control unit 400, which will be described later. , the control unit 400 operates the elevator car 100 by transmitting a control signal to the operating unit 200, which will be described later.

In addition, it further includes a microphone 120 that collects voice information of the occupants and a display 130 that outputs visual information. Furthermore, a speaker (not shown) is provided to collect the sound of the person on board (P) through the microphone 120 and communicate in real time with the remote control unit 500, which will be described later. That is, here, the elevator car 100 refers to an elevator car 100 that is installed in a building and runs up and down regardless of the type of building, such as a residential building, a commercial building, etc., and has the same configuration as the conventional elevator car 100. It consists of

As shown in FIG. 1, the surveillance camera 200 is installed in the elevator car 100 to capture the internal surveillance area of the elevator car 100 in real time. Here, the surveillance area refers to the range where the inside of the elevator car 100 can be photographed from the location where the surveillance camera 200 is installed, and the surveillance camera 100 can be zoomed in or zoomed out remotely from the remote control unit 500, which will be described later. You can set the surveillance area by doing this.

In addition, the direction in which the surveillance camera 200 is installed is installed at the top of the elevator car 100, and the direction in which the surveillance camera 200 is viewed is toward the door 110 of the elevator car 100. That is, it is installed at a location where a person (P) getting on or off through the door 110 of the elevator car 100 can be photographed in real time.

As shown in FIG. 1, the operating unit 300 provides power to move the elevator car 100 up and down, and is installed in the building where the elevator car 100 is installed. At this time, the operating unit 200 includes a power unit (not shown) that generates power to drive the elevator car 100 and a power transmission unit (not shown) that receives force from the power unit and moves the elevator car 100 up and down. ), including. That is, the configuration is the same as that of the operating unit 300 generally installed in an elevator, but is operated by the control unit 400, which will be described later.

As shown in FIG. 1, the control unit 400 transmits an operation control signal to the operation unit 300, detects boarding and exit of the person P in the elevator car 100, and operates the elevator car ( 100) Count the number of passengers inside. At this time, the control unit 400 is installed inside the elevator car 100 and includes a control unit 400 that controls the elevator car 100 and a system control unit that controls the entire system of the elevator. Accordingly, the control unit 400 may be installed inside the elevator car 100 or may be installed outside the elevator car 100 and connected to the operating unit 300.

As shown in FIG. 1, the remote control unit 500 is connected to the control unit 400 and a network (N) to transmit and receive information, and displays images captured by the surveillance camera 100 in real time through the monitor 120. The operating state of the elevator car 100 can be controlled by monitoring and remotely transmitting a control signal to the control unit 400. In addition, the remote control unit 500 is equipped with an emergency bell (not shown) that can immediately transmit a control signal to the notification transmission unit 600, which will be described later.

Therefore, if an emergency or dangerous situation occurs while the manager of the remote control unit 500 is monitoring the inside of the elevator car 100 through the monitor 510, the fire department or investigative agency is selectively contacted immediately through the emergency bell. Information can be transmitted.

As shown in FIG. 1, the notification transmitter 600 is connected to the control unit 400 and the network (N) to transmit and receive data, and receives data from the remote control unit 500 as a notification message 610. It is converted and selectively transmitted to a firefighting agency terminal (ET) or an investigative agency terminal (IT), so firefighters or investigators working at a firefighting agency or investigative agency can receive information in real time. At this time, the notification transmitting unit 600 may be a server provided in the remote control unit 500, or may be a button remotely connected to an organization or server that transmits the notification message 610.

Here, a firefighting agency refers to an agency that extinguishes a fire in the event of a fire or an emergency patient or provides first aid to an emergency patient and transports the patient to a medical institution. In the event of a crime, an investigative agency refers to an agency that suppresses or arrests the person who committed the crime. refers to an institution that

That is, the notification message 610 transmitted through the remote control unit 500 varies depending on the situation occurring inside the elevator car 100. For example, it is divided into an emergency situation in which a person inside the elevator car 100 collapses and a dangerous situation in which a person inside the elevator car 100 is threatened by another person, and a notification message 610 is sent for each situation. ) is transmitted.

Therefore, in order to determine the number of passengers inside the elevator car 100 and analyze the situation that occurred inside the elevator car 100, the control unit 400 first determines the number of passengers inside the elevator car 100. (P) is detected, and for this purpose, the control unit 400 includes a surveillance camera setting unit 410, a memory unit 420, and a motion detection unit 430.

First, the surveillance camera setting unit 410 sets the surveillance area of the surveillance camera 100 so that there is no blind spot inside the elevator car 100 that is not captured in the video captured by the surveillance camera 100. This is the place to do it. Here, when the surveillance camera 100 is set remotely from the remote control unit 500, the surveillance camera setting unit 410 receives a control signal from the remote control unit 500 and controls the surveillance camera 100.

Next, as shown in FIG. 1, the memory unit 420 divides the image of the surveillance area captured by the surveillance camera 100 into a plurality of blocks and stores them.

Subsequently, the motion detection unit 430 compares the image stored in the memory unit 400 with the subsequent captured image provided by the surveillance camera 100, and detects the image moving in a relatively different direction or at a different speed in the surveillance area. The block is determined to be a motion block 431, and the coordinate value and movement vector value of the motion block 431 are calculated and output as the person's motion information. At this time, the movement block 431 represents the person (P) riding inside the elevator car (100) in the form of a block, and its size and shape are displayed differently depending on the height and body shape of the person (P).

In other words, when a person (P) gets on the inside of the elevator car 100 and is located in the surveillance area of the surveillance camera 100, the motion block 431 is detected by the motion detection unit 430 and the person (P) moves into the elevator car. You will find out whether it is located inside (100).

Afterwards, the boarding and alighting of a person (P) inside the elevator car 100 is detected through the motion information provided by the motion detection unit 430, and the number of passengers is analyzed. For this purpose, the control unit 400 uses a boarding and alighting detection unit 440. and a passenger detection unit 450.

First, the getting on and off detection unit 440 detects a person (P) inside the elevator car 100 when the movement block 431 is detected by the motion detection unit 430 as shown in FIGS. 1 and 2. It is determined that the person has boarded the elevator car, and when the motion block 431 disappears from the motion detection unit 430, it is determined that the person P who got on the elevator car 100 has gotten off.

That is, the boarding and disembarkation detection unit 440 determines whether a person P has boarded or got off the elevator car 100 based on whether or not the motion block 431 provided by the motion detection unit 430 has been created.

Next, the occupant detection unit 450 counts the motion block 431 received from the motion detection unit 430 as shown in FIGS. 1 and 2 to determine the number of people riding inside the elevator car 100. The number of people (P) is stored as the number of passengers, and the number of people is transmitted to the remote control unit 500 to inform the number of people (P) present inside the elevator car 100.

That is, the number of passengers detecting unit 450 determines the number of people (P) riding inside the elevator car 100 by analyzing the number of movement blocks 431 provided by the motion detecting unit 430. Here, the motion block 431 is a plurality of motion blocks 431 that are detected after the door 110 of the elevator car 100 is opened and a person (P) gets on board and enters the surveillance area of the surveillance camera 100. Even if the number of people (P) gets on the elevator car (100), the order and time of entering the surveillance area of the surveillance camera (100) are different, and the moving direction is also different, so that the number of people (P) can be determined more accurately. do.

Here, the reason for determining the number of people (P) riding inside the elevator car 100 is to monitor the inside of the elevator car 100 for each situation. For example, when one person (P) gets on the elevator car (100), a dangerous situation does not occur because he or she is not threatened by other people, but he/she collapses due to illness and an emergency situation occurs. Furthermore, when multiple people (P) board the elevator car 100, the probability of a dangerous situation occurring is low, and even if an emergency situation occurs, quick help can be received from the people on board. Therefore, in order to accurately determine this situation, the control unit 400 is equipped with a monitoring mode setting unit 460.

As shown in FIGS. 1 and 2, the surveillance mode setting unit 460 sets the emergency situation monitoring mode when the number of people detected by the occupant detection unit 450 is one, and sends a message to the occupant detection unit 450. If the number of detected people is 2 or 3, it is set to crime prevention mode, and if there are 4 or more people, it is set to normal operation mode to monitor the inside of the elevator car 100, and if an emergency or dangerous situation occurs, the operation department A control signal is transmitted to 300 to control the operation of the elevator car 100.

That is, as shown in FIG. 3, when the elevator car 100 receives a signal and the door 110 is opened, the motion detection unit 430 of the control unit 400 is activated to generate the movement block 431, and the door ( When 110) is closed, the number of people on board the elevator car 100 is determined by the number of people (P) in the passenger detection unit 450, stored as number of people information, and transmitted to the monitoring mode setting part 460.

Thereafter, the monitoring mode setting unit 460 sets each of emergency situation monitoring mode, crime prevention mode, and general operation mode according to the number of people (P) on board and operates the elevator car 100.

Here, when the emergency situation monitoring mode is set in the monitoring mode setting unit 460, the control unit 400 uses a time measuring unit 470 to determine whether an emergency situation has occurred to the person (P) riding inside the elevator car 100. ) and an emergency situation reading unit 471.

First, the time measurement unit 470 is activated when the emergency situation monitoring mode is set in the monitoring mode setting unit 460, and measures the time after the motion information of the motion detection unit 430 is received and converts it into time information in real time. It is transmitted to the emergency situation reading unit 471, which will be described later. That is, the time measuring unit 470 generates a movement block 431 when a person (P) boards the elevator car 100, and when the elevator car 100 is operated or another movement occurs, a new movement block ( 431) is formed, and the time is measured again after the new movement block 431 is formed.

Next, the emergency situation reading unit 471 operates when the time measuring unit 470 is activated, stores the motion block 431 transmitted from the motion detection unit 430, and provides the motion block 431 from the motion detection unit 430. The size and movement direction of the motion block 431 are analyzed by comparing each subsequent motion block 431 with the stored motion block 431, and the time information received from the time measurement unit 470 and the set emergency situation are analyzed. Emergency situations are determined by comparing and analyzing decision time information. Here, the emergency situation determination time information is the time stored in the emergency situation reading unit 471 and is set in seconds, such as 5 or 10 seconds, and is a time set for relative comparison with the time measured in the time measuring unit 470. refers to

For example, when the person on board (P) falls inside the elevator car 100, the movement block 431 formed when first boarding the elevator car 100 and the movement block 431 formed after falling down have the shape and size. , the location changes. Additionally, when a person (P) falls down and loses consciousness, there is no movement and the positions of the motion blocks 431 detected by the motion detection unit 430 become the same.

Therefore, the emergency situation reading unit 471 determines the time from the time measurement unit 470 when the size of the stored motion block 431 and the size of the subsequent motion block 431 provided by the motion detection unit 430 are different. Upon receiving the information, the positions of the stored motion block 431 and the subsequent motion block 431 provided by the motion detection unit 430 are read.

Afterwards, the control unit 400 controls the movement stored in the emergency situation reading unit 471 while the time information received from the time measuring unit 470 exceeds the emergency situation judgment time information set in the emergency situation reading unit 471. If the positions of the block 431 and the subsequent motion block 431 provided by the motion detection unit 430 are the same, the notification transmission unit 600 transmits a notification message 610 to the fire engine terminal (ET). Then, the elevator car 100 is operated to the first floor of the building where the elevator car 100 is installed, and the operation unit 300 is controlled to force the door 110 to open and make an emergency stop. At this time, the reason for forcing the elevator car 100 to move to the first floor is to allow the fire department to quickly respond to an emergency situation after moving to the location where the elevator car 100 is installed.

For example, if the elevator car 100 comes to an emergency stop after stopping on the upper floor, the fire department must arrive and then take the stairs to the floor where the elevator car 100 is located. Accordingly, the time required to provide assistance to a person (P) in an emergency situation increases, so the elevator car 100 is forced to run to the first floor and then makes an emergency stop.

In addition, at this time, the notification message 610 transmitted from the notification transmitting unit 600 provides information about the building where the elevator car 100 is installed, as well as the location and emergency situation occurrence time of the building where the elevator car 100 is installed. This is the content.

That is, the control process of the emergency situation monitoring mode is as shown in FIGS. 4 and 7 to 11, when a person (P) gets on the inside of the elevator car 100, the number of people on board is detected by the number of people on board (450). If there is only one person on board, the elevator car 100 is operated in emergency situation monitoring mode in the monitoring mode setting unit 460. Here, as soon as the emergency situation monitoring mode is activated, the time measuring unit 470 is activated to continuously check the time since the movement block 431 was formed.

At this time, if the formed movement block 431 is maintained for longer than the emergency reimbursement judgment time stored in the emergency situation reading unit 471, it is determined that an emergency situation has occurred and the control unit 400 moves the elevator car 100 to the elevator car 100. ) is forcibly stopped at the floor where the elevator car (100) is located or the next floor, and then forced to run to the first floor of the building where the elevator car (100) is installed. In addition, at the same time as forcing the operation, the manager of the remote control unit 500 is notified so that he can recognize the fact that an emergency situation has occurred inside the elevator car 100.

After the manager of the remote control unit 500 recognizes that an emergency situation has occurred, the manager checks the emergency situation once more through the monitor 510 of the remote control unit 500 and sends a notification message 610 to the notification transmitter 600. Arrange for it to be transmitted to the fire engine terminal (ET). Afterwards, when the emergency situation is resolved, the remote control unit 500 transmits an emergency stop release signal to the control unit, and the control unit 400 transmits a control signal to the operation unit 300 to allow the elevator car 100 to operate normally again. It will happen.

Continuing, when the crime prevention mode is set in the surveillance mode setting unit 460, the sound volume measuring unit 480 and the movement reading unit are used to determine whether a dangerous situation has occurred to the person (P) riding inside the elevator car 100. (481) is further provided.

The sound volume measurement unit 480 is activated when the surveillance mode setting unit 460 is set to the crime prevention mode, and receives the sound volume information of the person (P) collected by the microphone 120, reads the decibel, and converts it to the current decibel information. It is stored and compared and analyzed between the stored current decibel information and the set risk decibel information.

In other words, it is determined whether a dangerous situation has occurred inside the elevator car 100 by using the characteristic of a person (P) screaming or making a louder and higher-pitched voice than usual in a dangerous situation. However, if the internal situation of the elevator car 100 is judged only through sound volume information, that is, decibels, an error may occur in selling a non-dangerous situation as a dangerous situation. For example, when a young child runs or screams and plays inside the elevator car 100, the sound volume measurement unit 480 may determine that a dangerous situation has occurred.

In order to solve the above problem, the motion reading unit 481 determines the internal situation of the elevator car 100 once again.

The motion reading unit 481 operates when the volume measuring unit 480 is activated, receives each motion block 431 from the motion detection unit 430, and sends a velocity vector to each of the motion blocks 431. By generating and reading the movement, it is determined whether a dangerous situation has occurred inside the elevator car 100.

That is, when it is determined that the current decibel information stored in the sound volume measurement unit 480 is greater than the dangerous decibel information, a control signal is transmitted to the motion reading unit 481 to activate the motion reading unit 481 to read the movement. The unit 481 generates a speed vector to determine whether a dangerous situation has occurred.

Here, the speed vector indicates the direction and speed of movement that occurs in the image by gradually changing the brightness of the image in which the motion block 431 detected by the motion detection unit 430 is created in the image captured by the surveillance camera 100. , the movement of the motion block 431 occurring from the difference between the frames of the stored motion block 431 and the subsequent motion block 431 is estimated, and the movement of the person (P) is determined by distinguishing between blocks in which movement occurred and blocks in which movement did not occur. The movement and direction are analyzed.

Thereafter, the control unit 400 operates the notification transmission unit when each of the motion blocks 431 detected by the motion detection unit 430 is formed in an atypical manner and at the same time, motion blocks 431 with speed vectors pointing in different directions are formed. At (600), a notification message 610 is transmitted to the investigative agency terminal (IT), the elevator car 100 is stopped at the current floor or the next floor where the elevator car 100 is located, and the elevator car ( After forcibly opening the door 110 of the vehicle 100, the operating unit 300 is controlled to make an emergency stop.

At this time, when the elevator car 100 makes an emergency stop through the display 130 installed inside the elevator car 100, the manager video of the remote control unit 500 is transmitted in real time to indicate the situation in which the criminal is being monitored. By recognizing and running away from the elevator car 100, the person on board (P) may be able to quickly escape from a dangerous situation.

Here, the notification message 610 transmitted from the notification transmitting unit 600 not only provides information about the location of the building where the elevator car 100 is installed and the time of occurrence of a dangerous situation, but also contains information about the criminal captured by the surveillance camera 100. Video may also be included.

That is, the control process of the crime prevention mode is as shown in FIGS. 5 and 12 to 17, when a person (P) gets on the inside of the elevator car 100, the number of people on board is detected by the number of people on board detection unit 450. If the number of passengers is 2 or 3, the surveillance mode setting unit 460 operates the elevator car 100 in crime prevention mode. Here, as soon as the crime prevention mode is activated, the sound volume measurement unit 480 is activated to continuously measure the sound generated inside the elevator car 100 through the microphone 120.

At this time, if it is determined that the decibel information of the generated sound volume is greater than the dangerous decibel information, the motion reading unit 481 is activated. Afterwards, the motion reading unit 481 generates a speed vector of the movement block 431 to analyze the movement, and if the analyzed information is determined to be a dangerous situation, the control unit 400 moves the elevator car 100 to the elevator car 100. The operation is terminated after being forced to stop at the current floor or the next floor where is located. In addition, at the same time as determining a dangerous situation, the manager of the remote control unit 500 is notified so that he or she can recognize that a dangerous situation has occurred inside the elevator car 100.

The manager of the remote control unit 500 recognizes that a dangerous situation has occurred, checks the dangerous situation once more through the monitor 510 of the remote control unit 500, and sends a notification message 610 to the notification transmitter 600. Arrange for it to be transmitted to the investigative agency terminal (ET). Afterwards, when the dangerous situation is resolved, the remote control unit 500 transmits an emergency stop release signal to the control unit, and the control unit 400 transmits a control signal to the operation unit 300 to allow the elevator car 100 to operate normally again. It will happen.

Finally, when the normal operation mode is set in the monitoring mode setting unit 460, as shown in FIGS. 6 and 18, the elevator car 100 operates normally to the floor to which the person on board (P) wants to move. Various images are transmitted through the display 130 installed inside. At this time, the transmitted video may greet you through an image or a moving character, ask the number of floors to be moved, print notices of the building where the elevator car 100 is installed as text, or provide various event information to the person on board (P). It may be a video that includes text and images for easier viewing.

Thereafter, when the elevator car 100 arrives at the floor to which it is to be moved and the person on board (P) gets off, the operation ends.
