Description

Interlocking station control system for train emergency stop using platform image information {train station control system for train emergency stop using Platform vision information}

The present invention relates to an interlock station control system for train emergency stop using platform image information. More specifically, the present invention relates to emergency stop control information from an image based platform monitoring system of a platform in case of a dangerous situation caused by a passenger's track fall. The present invention relates to an interlock station control system for emergency stop using train station image information that can prevent the safety accidents caused by the collision of trains in the station by emergency braking the trains entering the station of the received station.

In general, railways are a popular and convenient means of transportation on a large scale. However, because railroads are used by many passengers, many casualties can occur with only one inadequate safety management.

In particular, recent accidents caused by falls on the platform of subways, accidents in which clothes or body parts get stuck in the doors of trains during commute times, and a part of passengers in the gap between platform and railroad car. Safety accidents on railroads, such as accidents that are falling off, are becoming more frequent.

Of course, in order to monitor such safety accidents in the platform, the current CCTV is installed and operated in the subway station yard, but the CCTV must be monitored continuously by the operator in the command room or the station office, so the immediate recognition and emergency It was difficult to establish countermeasures, and was operated passively and limitedly, which made it difficult to recognize and respond quickly to emergency situations.

On the other hand, in recent years, the installation of screen doors (PSDs) has been expanded in order to prevent passengers from crashing in advance. However, it is economically expensive to install them on all platforms, especially in the case of ground platforms. It also has the drawback that it can block passengers and increase their frustration.

In addition, when the train does not stop in the right position may cause problems in the opening and closing of the screen door, it is difficult to prepare for the case of the human body or objects in the gap between the screen door and the train.

Of course, in order to solve such a problem, the present applicant has proposed the image-based platform monitoring system. It relates to a system for monitoring the danger area of the platform to recognize and respond quickly and accurately to the emergency and emergency situation in the platform, and trains and objects in the platform using the image information obtained by using the camera The information collecting unit for detecting whether the object falls and generating monitoring information, an information fusion unit for generating an alarm message using the monitoring information of the information collecting unit, and sending the alarm message information of the information fusion unit to the receiving apparatus. It consists of an information provider.

With this configuration, when a passenger's danger is detected, such as when an object enters a train area into which a train enters the platform and a dangerous area where an object can fall, the motion information of the camera image frame is traced back. Determining the risk of falling can be dealt with quickly and accurately, which has the advantage of minimizing the loss of valuable lives and property.

However, in the case of the registered patent, despite the above-mentioned advantages, the emergency stop of the train is required in the event of an emergency, such as a passenger's track crash, but the information fusion unit is simply a receiver (for example, a command room employee, a station attendant, an entry train driver). It is necessary to analyze the alarm message according to the characteristics of the message and send the alarm message according to the characteristics of the alarm and take the appropriate action accordingly. Therefore, it takes a lot of time due to the decision and the operation. There is a problem that cannot be coped.

Accordingly, the present invention is to solve such a problem, when the emergency stop control information forbidding the entry of the train from the image-based platform monitoring system for detecting a passenger fall in the platform and receives the platform through the field signal equipment of the interlocking station The purpose of the present invention is to provide an interlocking station control system for emergency stop using train image information to prevent trains from entering the platform by controlling the train to stop upon entering.

At this time, when the emergency control information is received, the field control console 210 stops the condition of the on-site signal display in the case of a train automatic stop device (ATS) for the emergency stop of the train before entering the platform of the interlocking station. In the case of ATC or ATO, the speed code transmitted from the ground signal to the vehicle is transmitted as 'zero code'.

Meanwhile, the field control panel 212 doubles the emergency stop button circuit of the field control panel 212 in order to receive the emergency stop information generated from the image-based platform monitoring system 100 and the image-based platform through one of them. The output of the monitoring system 100 is received. In this case, when the output of the image-based platform monitoring system 100 is DC24V, the circuit of the on-site control panel 212 is operated so that the corresponding interlocking station section becomes a closed section, the section is controlled to enter the train, the section entry train Will enter emergency stop braking.

In this case, the information analysis unit 120 for generating emergency stop control information and the emergency stop control information of the information analysis unit 120 to the field control console 210 or the site control panel 212 installed at the site of the interlocking station. It consists of an information transmitter 130 for transmission.

Hereinafter, each component will be described in more detail.

First, the information collecting unit 110 detects and recognizes a dangerous situation such as a fire in the platform 1 or a track fall or jamming of a passenger. To this end, the information collecting unit 110 is installed to face toward the track (2) of the platform (1) to determine whether the object located on the track using an infrared sensing method in the situation that can not be forward-looking due to pesticides. A thermal imaging camera (112) for acquiring an image and a stereo camera (114) for acquiring an image for measuring a distance from an object located on the track (2) of the landing (1).

At this time, the information collecting unit 110 is installed in the lower part of the platform 1, the infrared sensor 116 for detecting the object of the detection area on the track 2 side to maintain a predetermined interval and install a plurality of about 30cm height. Therefore, when a person, such as a passenger, falls in the platform, the vehicle may be used as the determination information regarding the presence or absence of the fall as detected by the infrared sensor 116.

In particular, the information collecting unit 110 is installed in at least one platform (1) to obtain the image information about the train and the object for each specific location and to detect the track fall or danger using it.

On the other hand, the information analysis unit 120 determines whether the object located on the track is more than a certain size or an obstacle that can cause an abnormality in the progress of the train, emergency stop control information for emergency stop of the entry train as needed By generating the control, it is possible to control the entry train and to deal with accidents.

The information analyzer 120 determines whether an object of the infrared image photographed through the thermal imaging camera 112 is an organism using the monitoring information collected by the information collector 110, and the stereo camera 114. After calculating the distance from the object using a stereo image taken through, if the object of the infrared image of the thermal imaging camera 112 is a living organism using the distance information with the object to calculate the size of the human In case of discrimination, emergency stop control information is generated to induce emergency stop of train.

In more detail, the information analyzer 120 first analyzes an object of the infrared image photographed by the thermal imaging camera 112 to determine whether it is an organism.

On the other hand, the information analysis unit 120 may cause a train delay or the like when the object is unrecognized as a person even though it is determined as a living organism as a result of analyzing the object of the infrared image photographed by the thermal imaging camera 112. Therefore, when the infrared image photographed by the thermal imaging camera 112 is analyzed and the object is recognized as an organism, the distance from the object is calculated by analyzing the stereo image photographed by the stereo camera 114.

As such, when the distance from the object is calculated, the information analyzer 120 may calculate the actual size of the object using the calculated distance information and the size information of the object on the screen. In this case, if the actual size of the object is more than a certain size is determined as a person, if it is less than that can be understood as a cat or a mouse and can be ignored.

Therefore, the information analyzer 120 determines that a person is located on the track due to a track fall when the object captured in the image is a living being, and the size of the object is determined to be similar to the person. Create emergency stop control information to induce an emergency stop.

In this case, even if it is determined as a person, whether or not the person has fallen in the platform may use information detected through a separate infrared sensor 116, and the detection signal is transmitted to the information analyzer 120 through the infrared sensor 116. If it is input, it can be determined in more detail that the passenger in the landing (1) has fallen.
