Description

{METHOD FOR AUTOMATICALLY DETECTING AND ALARMING UNEXPECTED ACCIDENT WHILE BOARDING OR ALIGHTING FROM SUBWAY AND TRAIN AT PLATFORM}

According to the present invention, when a user in a subway / train platform gets on or off, a sudden accident such as a body or object jamming between the doors of a vehicle or a rush between the vehicle and the platform occurs, and automatically detects and immediately issues the corresponding alarm. Automatic detection and alarm method of urban accidents, and in particular, the automatic detection and alarm method of accidents when getting on and off subways / trains according to the present invention uses an image processing alarm system that automatically detects and alarms the sudden situation of subways / railways. When a user in a subway / train platform gets on or off, if a sudden situation such as a body or object gets caught between the doors of a vehicle, or a foot falls between the vehicle and the platform, the accident is automatically detected and voiced through a wired / wireless communication line. And / or subways that can be alerted more effectively by issuing in the form of video data It relates to the automatic detection and alarm of accidents when getting on and off the train.

Current subway / train platforms are marked with a safety line indicating the distance that the passenger should be separated from the vehicle until the vehicle has completed entry or departure. Safety lines are marked on the outside of the platform at regular intervals from the track to prevent passengers waiting for the vehicle from being swept or hit by passing, entering or departing tracks and inadvertently colliding with vehicles entering the platform tracks. Access control line.

Accordingly, passengers protect themselves from vehicles entering at high speed by adhering to the safety line at the time of entry and departure of the vehicle, and evacuate safely into the safety line at the time of vehicle entry or departure by horn sound and guidance broadcasting of the vehicle.

On the other hand, in addition to paying attention to the safety of the passengers themselves, the operator of the vehicle reminds the passengers of danger through an alarm sound or an announcement to inform them of the entrance and departure of the vehicle. Efforts are being made to prevent accidents by installing cameras and monitors to check the situation, or by deploying separate safety personnel.

Nevertheless, carelessness or other unforeseen reasons may lead to accidents in which passengers may fall onto the platform tracks or be caught in gaps in the vehicle or between the vehicle and the platform.

Risk factors caused by actual falling objects and accidents caused by human life falls are very insufficient in terms of personnel and facilities in order to cope with safety personnel and manual alarm devices in current subway / train platforms. In addition, the response of the careful forward attention or safety speed compliance and instantaneous deceleration through the naked eye of the existing vehicle driver is not enough to respond to the sudden situation in real time, and the main task of the vehicle driver is to drive the vehicle safely. As can be, even if the monitor installed inside the vehicle can check the boarding state of the user in the landing and the door opening and closing state of the vehicle when getting on / off, there was a problem that is difficult to cope with the sudden situation by continuously monitoring it.

Therefore, in addition to paying attention to the accident, the passengers can immediately detect the accident in the vehicle, the station office, and the situation command room to control the operation of the vehicle or to perform the immediate response to the accident.

Nevertheless, many people who use subways / trains take appropriate measures in case of accidents such as body or object being caught between the vehicle doors that are closed while getting in and out of the vehicle, or falling out between the vehicle and the platform. It is true that the method is insufficient.

In addition, the existing method of visual monitoring of CCTV monitors installed inside the platform monitors the unexpected situation of a large number of passengers and provides the necessary information to protect vehicle driver and passenger safety by warning of danger in advance. I could not.

Briefly describing the configuration of the automatic detection image processing alarm system of the subway / railway platform accident situation, the imaging device 10 is a zone in which a monitoring area (for example, a platform safety line, a platform track part, etc.) is located. Take an image of an image and input it to the image converting apparatus 30, and the image converting apparatus 30 converts the image signal received from the image capturing apparatus 10 into a digital signal. It is stored in the sensing module memory (not shown). The sensing module reads an image stored in the memory, performs necessary image processing, and detects a sensing object through a sensing algorithm. In addition, the sensing module of the image processing apparatus 40 extracts various movement path information of the sensing target, and outputs a video and audio warning by transmitting it to the alarm controller 50 when a sudden situation occurs.

In particular, the imaging apparatus 10 sets a space outside the safety line of the subway / train platform as a sudden monitoring region according to the present invention, controls the imaging apparatus to continuously capture an image of a designated region, and the designated region. To monitor video changes

On the other hand, the image processing device 40 transmits a control signal for controlling the operation and movement of the imaging device 10 based on the result of analyzing the image in the sensing module.

The alarm controller 50 receives a control signal from the image processing device 40 and transmits an alarm control signal S2 to the station / room command room 100 and the image splitting device 60, and the linkage alarm. The device 110 sends an alarm interlocking control signal S3. In addition, the alarm controller 50 receives a platform fire alarm signal S5 from the fire detector 90 and transmits an alarm control signal S2 to the station room / situation command room 100 and the image splitting device 60. The alarm interlocking control signal S3 is sent to the interlocking alarm device 110.

2 is an exemplary view showing the arrangement of the image pickup device of the automatic detection of the subway / railway platform accident situation detection system to which the accident detection and warning method when the subway / train getting on and off in accordance with a preferred embodiment of the present invention, Figure 3 Is a control flowchart illustrating a method of automatically detecting and alerting an accident situation when getting on and off a subway / train according to a preferred embodiment of the present invention.

Hereinafter, a method of automatically detecting and alerting an accident situation upon getting on and off a subway / train according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

In the image processing alarm system to which a method of automatically detecting and alerting of an unexpected situation of a subway / train platform according to the present invention is applied, as shown in FIG. 2, an imaging device 10 is installed at predetermined positions in the platform, respectively. The image of the designated surveillance zone is photographed at each position, and the change of the designated surveillance zone is detected.

The imaging apparatus 10 includes a control camera for continuously capturing an image of the designated surveillance zone, and an image sensing camera for performing a function of sensing a change occurring in the designated surveillance zone. As shown in an embodiment of the present invention, the control camera function and the image detection camera function may be integrated into a single camera and may include a multifunctional camera that performs the above functions in combination.

The image distribution device 20 applies an operation control signal of the imaging device 10 which is transmitted based on a result of analyzing the image by the sensing module of the image processing device 40 to the imaging device, and the imaging device ( 10) receives the captured image and transmits the captured image signal to each component that processes the captured image signal such as a station room, a situation command room, an image conversion device, and an image splitting device. In this case, the image distribution device 20 amplifies the captured video signal S1 received from the imaging device 10 to faithfully adhere to the original video video signal, and transmits the amplified video signal S1 to the office / situation command room 100.

The image conversion apparatus 30 converts the analog image signal received from the image distribution apparatus 20 into a digital image signal. In particular, the image conversion apparatus 30 converts the analog image signal into a high resolution digital image signal in order to perform the automatic detection image processing according to the present invention.

The image processing apparatus 40 processes the digital image signal converted from the image converting apparatus 30 according to the auto-sensing image processing algorithm according to the present invention, causing the vehicle driving hazards and the fall of the platform at the platform, and other platform accidents. It automatically detects the situation, and when the accident occurs, immediately generates an alarm signal including the image signal information in which the accident occurred.

Extraction of the sensed information using the image processing according to the present invention can be largely divided into a method using a tripline and a tracking method for tracking the movement of the moving object.

First, in the case of a tripline algorithm, a tripline is generally installed at the center of an area to be monitored in an image, and a gray level between the reference image and the current surveillance area image is included in the installed tripline area. Traffic information is calculated by analyzing the difference or feature value of). This method only handles a given region, so the computation is small and the algorithm is relatively complex.

The information resulting from the tripline detection algorithm is primarily information on the presence or absence of a sensing target. Using this information, the size of the sensing target can be directly obtained and the two triplines are used to detect the size. The amount of displacement of the target can be obtained. However, since this method can only know the movement of the moving object at a predetermined position, it is difficult to obtain accurate information due to the change inducing factors such as environmental factors. However, this method plays an important role in providing trigger information that informs when the target is tracked in the tracking method for tracking the movement of the sensing target. Therefore, the algorithm of this stage must have good performance to perform good performance in the tracking stage of the sensing target. Can make

Second, the tracking algorithm that tracks the motion of the sensing object separates the area of the sensing object from the background, obtains the necessary information by predicting the movement direction of the area of each object, and predicts the position in the next image. The detection object is tracked in an arbitrary direction. By using this method, information on the movement of the sensing object can be obtained, so that the speed and occupancy information can be obtained more accurately than the tripline method, and information about the change of the moving direction of the sensing object or the moving situation of the monitoring area can be extracted. Can be. However, when images of a plurality of sensing targets overlap during tracking of a sensing target, a problem occurs in that only one sensing target is visible in the image, thereby causing a problem of losing the sensing target during tracking of the sensing target. Therefore, in order to solve the problem of overlapping two sensing objects, it is necessary to distinguish and recognize the areas of each sensing object.

Therefore, the tracking method of the sensing object requires the process of separating the sensing object from the sensing object area, the process of recognizing the sensing object, and the process of predicting the recognized area. It requires a powerful computing system.

Accordingly, the image processing apparatus 40 is provided with a sensing module to install a trip line (trip line) in the center of the area to be monitored in the landing image, and the reference image and the monitoring in the area of the trip line installed A tripline algorithm that determines whether a sensing object exists by comparing and analyzing the change of gray level of the region image, and after separating the region of the sensing object from the background in the reference image, movement of the region occupied by each sensing object A multi- algorithm operation is performed by combining a tracking method algorithm for obtaining a direction and determining a movement state of the sensing object determined by the tripline method algorithm.

The alarm controller 50 receives the alarm signal including the image signal information from the image processing device 40, the occurrence of the sudden situation, the emergency room / situation command room 100 and the on-board device 80 to the accident situation The alarm control signal S2 including the generated video signal information is generated and transmitted. The alarm control signal S2 transmits an image in which a sudden situation occurs along with a voice alarm in real time.

The alarm controller 50 also generates an alarm interlocking control signal S3 including the alarm control signal S2 when the accident occurs and generates an alarm sound as necessary at one side of the platform. It transmits to the interlocking alarm device 110 such as a device and a traffic light. Accordingly, the engineer of the station / situation command room 100 receives an alarm not only through the video and audio alarm but also through the interlocking alarm device 110, thereby experiencing a three-dimensional alarm system.

The image splitting device 60 divides the video signal according to the monitor screen so as to integrate and display a plurality of video signals photographed from the image capturing device 10 into one monitor, and the alarm controller 50. According to the alarm control signal (S2) from the predetermined divided video signal to select the video signal in which the sudden situation occurs, the image segmentation is released so that it can be enlarged and displayed on the monitor.

That is, the plurality of video signals photographed from the imaging device 10 are displayed in multiples by dividing one monitor screen, and the video signal in which the abrupt situation occurs among the plurality of video signals photographed from the imaging device 10 is The monitor screen is displayed in its entirety without being divided so that it can be immediately identified.

On the other hand, the video splitting device 60 performs a caption function that can insert, delete, and edit text, numbers, and time display signals in the video signal.

The wireless transmission device 70 wirelessly transmits the video signal received from the video distribution device 20 and the video signal from which the unexpected condition received from the video splitting device 60 occurs to the onboard device.

As shown in FIG. 3, the automatic detection and warning method of accidents when getting on and off the subway / train according to a preferred embodiment of the present invention sets a space outside the safety line of the subway / train platform as a sudden monitoring area, and the imaging device. By controlling the continuous shooting of the image of the specified area, and maintains a state of monitoring the image change of the specified area.

Subsequently, in step 301 of FIG. 3, it is determined whether there is a vehicle in the landing 220, and if there is a vehicle in the landing 220, the image control apparatus 10 is controlled in step 303 to display an image of the area between the vehicle and the safety line. Monitor the change.

In step 305, the area occupied object is detected according to the image change in the surveillance area. If the occupied object is detected in the surveillance area, the controller proceeds to step 307 to issue a departure warning to the vehicle.

On the other hand, if there is no vehicle in the landing 220 in step 301, the imaging device 10 is controlled to monitor the image change of the area 210 between the safety line and the track, and in step 311 the image in the surveillance area The area occupant is detected according to the change.

When the occupied object is detected in the monitoring area in step 311, the controller proceeds to step 313 to issue a track attention alert to the station office, and when the track attention alert is issued, the track attention announcement is performed in step 315.

In addition, if there is no vehicle in the landing hall 220, the imaging apparatus 10 is controlled to monitor the image change of the area between the landing and the track in step 317, and the operation proceeds to step 319 in accordance with the image change in the monitoring area. Detect occupied objects.

When the occupied object is detected in the monitoring area in step 319, the control unit proceeds to step 321 to issue a slow driving warning to the vehicle and the station room.

When the slow driving alert is issued, the slow driving guidance broadcast and warning broadcast may be performed from the station office in step 323.

In addition, if there is no vehicle in the landing hall 220, the image capturing apparatus 10 is controlled in step 325 to monitor the image change of the area on the track, and in step 327, the object occupying object is detected according to the image change in the monitoring area. do.

When the occupied object is detected in the monitoring area in step 327, the controller proceeds to step 329 to issue a sudden stop alarm to the vehicle, the station room, and the situation command room. In step 329, when the sudden stop alarm is issued, in step 331, an emergency site investigation command is given to each station employee from the corresponding station office according to the sudden stop alarm command, and the guidance and warning broadcast of the sudden situation are automatically transmitted. And control the accidental alarm to be automatically issued from the situation command room.

At this time, the departure attention alert, track attention alert, slow running alert and sudden stop alert are issued in the form of audio and / or video data through a wired / wireless communication line.

4 is a histogram showing an image frequency distribution depending on whether a detection target is automatically detected when getting on and off a subway / train according to a preferred embodiment of the present invention.

The presence or absence of a sensing object according to the present invention is a function of observing a tripline region to find out whether a sensing object exists in the region, and is very useful for an automatic accident detection function in the platform.

The presence or absence of the detection target is set to the track line of the platform to detect a sudden accident such as falling objects or falling of the user in real time, and also to track the detection target to determine whether or not the ability to avoid the accident situation of the falling target By measuring the occupancy of the sensing object in the section measuring the speed to measure the speed, it performs a triggering function to start the next step (Object Tracking).

Since the detection target presence or absence algorithm must operate in real time 24 hours, above all, adaptability, robustness, and brevity are essential. The determination of the presence or absence of the detection object here calculates a value that can determine the presence or absence of the detection object in the image, and compares the result with a threshold to determine the presence or absence of the detection object. At this time, the threshold, which is a criterion for determining the presence or absence of a sensing object, can be applied simultaneously without any external intervention by considering the effects of shadows and lights and the day and night in order to adapt to changes in the environment.

In the division of the day and night, in the case of the ground platform, it is easy to distinguish when there is a sensing object on the sensing area and when there is no sensing object in a normal sunny weather. Usually, the gray level distribution of the pixels in the sensing region in the absence of a sensing object has a slight variation but a single Gaussian distribution symmetrically gathered around a constant value as shown in FIG. 4.

As described above, the present invention continuously monitors the space outside the safety line of the platform boarding area in the platform by a plurality of imaging devices, when the space occupied object is detected between the vehicle and the safety line when the vehicle is stopped at the platform, Automatically issue a departure warning to the vehicle.

In addition, if a space occupant is detected between the safety line and the track when there is no vehicle in the platform, a warning of the track caution is automatically issued to the corresponding station, and the user is guided to withdraw from the station in the safety line according to the warning of the track caution. To broadcast the broadcast automatically.

In addition, if a space occupied object is detected across the platform and the track when the vehicle is not in the platform, a slow driving warning is issued to the best vehicle entering the station and the corresponding station, and the above station is alerted by the corresponding station. Slow motion guidance announcements and broadcasts alerting the removal of objects on the track outside the safety line are automatically issued.

In addition, if an unknown space occupied object is detected on the track when the vehicle is not in the platform, a sudden stop alarm is issued to the best vehicle entering the station, the corresponding station and the situation command room, and according to the sudden stop alarm Receive an emergency site investigation order from each station, and send out emergency situation alerts and warnings automatically. In addition, the accident situation alarm is automatically issued from the situation command room.

At this time, the departure attention alert, track attention alert, slow running alert and sudden stop alert are issued in the form of audio and / or video data through a wired / wireless communication line.

Accordingly, the present invention, when the user in the subway / train platform when getting on and off the body or object jamming between the door, when the accident occurs, such as falling between the vehicle and the platform, automatically detects this to alert more effectively the accident situation Automatic detection of accidents when getting on and off subway / train, which can issue various alarms to the vehicle, station office, and situation command room in both directions using wired / wireless communication lines in the form of voice and / or video data.
