Information integrated railway system {INFORAMATION INTEGRATED RAILWAY SYSTEM}

The present invention relates to an information integrated railway system, and more particularly, based on information provided by an application program of each sub-system using information of a completed data model by collecting sensor information of a site through a sensor network. It is about an integrated railway system that can make decisions quickly and quickly.

Today's railroads are the most common means of transport for passengers and cargo on land, and they are used as the most efficient means of transport in many countries due to the on-time timing of on-time tracks.

Accordingly, the occurrence of railway accidents caused by abnormal safety of railway facilities will lead to catastrophic disaster. For this reason, conventionally, equipments and tracks for checking rail damage of rails, lifting rails, crushing of gravel, rolling spans of rails, turnouts, etc. to monitor the safety of railway facilities. Inspection vehicles equipped with equipment for observing railway structures such as grounds, bridges, and tunnels that support them are operated directly at the railway site to monitor the safety of railway facilities.

However, since railroad facilities are installed in a large area, the manager cannot check in real time whether or not the railroad facilities installed in a large area have a safety abnormality when managing railroad facilities using a conventional railroad facility safety monitoring method. In addition, since the time to check whether the safety abnormality of the railroad facilities occurs is late, there is a problem that can not prevent the railway accident in advance.

In addition, most of the surveillance system applied to the urban railway service section is a passive surveillance system using CCTV (Closed Circuit Television). Such a railway monitoring system is monitored by the operator using a large number of monitors and cameras to monitor the status of passengers or major facilities using urban railways.

In addition, a number of cameras are installed in the main aisle, escalator, platform, etc. in order to monitor the history of railway vehicles moving and stopping in the urban railway service space, and the images captured by these cameras are collected by an image collecting device. It is then sent to the place where it is needed, such as a platform monitor or a station room monitor.

For example, the monitor displays the image of the platform on the platform monitor installed at the front end of the platform so that the driver can check the image acquired by the surveillance camera installed in the platform.The monitor device is installed in the station room. Mark on.

The images acquired from the surveillance cameras installed in the platform or station are stored separately in the image storage device of the station.

Hereinafter, the operation of the information integrated railway system according to an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

First, the information-integrated railway system according to an embodiment of the present invention, wireless communication that can grasp real-time information on the site control and status, such as ground infrastructure (signal, power, track, civil engineering), rolling stock, passengers, cargo, etc. Based sensor network.

Therefore, the data collection device 200 receives the site control information and the state detection information from the field sensor device 100, receives the field control information, and converts the digital data into the digital data and transmits it to the information integrated processing device 300.

Therefore, the decision module 330 accurately predicts the time required from the time of the accident to the operation resume while minimizing the intervention of the manager or the operator based on the information provided by each application to quickly make a decision about the operation resume. Do it.

For example, in the event of an accident involving a railway vehicle, a large number of railway vehicles are in operation at the site, but if a specific vehicle suddenly stops, minimal time and effort should be put into analyzing the cause of the accident, which has little effect on the reliability and safety of the system. Not crazy

However, in the past, a lot of time and effort have been spent because the manual stationary work has to be performed on individual stationary vehicles to investigate and analyze a series of information related to the sensor system, reverse control system, and central control system. It was difficult to predict the time from the time of the accident to the resumption of driving due to the analysis of the cause of the accident and the decision making structure.

However, since the information integrated railroad system according to the embodiment of the present invention is modeled by the data of the functions of the lower system of the vehicle on the route, when the error is detected in the input terminal of each data model, the decision module 330 easily detects the error. Identify the cause of an accident and make decisions based on information provided by each application without relying on sensor information in the field.

That is, when the railroad vehicle is stopped due to a door-related sub-system problem, since the door-related data model lacks the on-site state detection information, the door model collects door-related state detection information through the sensor network to complete the data model. The application is developed by using the information of the completed data model, and the decision making is performed based on the information provided by the application so that the information can be integrated in real time from the sensor information of the field to the decision making. .

Although described with reference to the embodiments above, those skilled in the art will understand that the present invention can be variously modified and changed without departing from the spirit and scope of the invention as set forth in the claims below. Could be.
