It relates to a technical support system.

At present, there is a limit to the maintenance of electric facilities in the domestic railway as a post-maintenance system such as on-site inspection, maintenance, work execution and measures. In addition, diagnostic data on train lines / power, communication, and signals used in railways were manually managed and analyzed in each field and at each business unit. This maintenance system moves at each location confined to the relevant system field, and as a result, there is no information exchange between the systems, and thus the cooperation between the fields is not necessary, requiring comprehensive management due to reduced efficiency, and consequently the reliability of railway operation. This will be degraded.

In the existing railway electric equipment maintenance system, new equipment monitoring and control systems have been installed in the substation, train lines, and electric power fields according to the unmanned trend of facility inspection and monitoring, but each system has an independent monitoring system. It is difficult to analyze the cause of failure due to different configuration forms between systems and incompatibility of information and compatibility, and it is not efficient because only static data is used.In the case of information and communication, an independent monitoring system is constructed and operated for each device. However, due to the different protocols and configurations, separate devices are installed for each facility, resulting in low utilization of computational resources and the duplication of maintenance personnel composition.In the case of signal control, an electronic interlock device, track circuit function monitoring device, and crossing information analysis Information on operating devices, etc. The oil and do not link the comprehensive management of train operation control that situation does not occur.

In other words, the electrical facilities operated by KORAIL are classified into substation, train / electricity, information and communication, and signal control facilities. Therefore, the maintenance tendency of railway electric field is post maintenance system. There is a problem that efficiency decreases due to absence, and it is difficult to share core technology by operating separate management system by sector and device, and work efficiency decreases due to the lack of information utilization. The trend is that current remuneration systems are subject to high manpower dependence and lower efficiency.

The technical problem to be solved by the present invention is the inspection and diagnosis method depending on the manpower by comprehensively managing the data of the various functional monitoring devices in the operation of each unit of the railway electric equipment, unit by device and constructing a system capable of real-time diagnosis and analysis It is to provide a railroad electrical equipment technical support system that can automate, prevent, repair and manage comprehensively.

Railroad electrical equipment technical support system according to an embodiment of the present invention for achieving the above technical problem, the substation, electric business, signal control office, communication network management and communication network. The substation office monitors the overall factors of power supply in each region and has a first data concentrating device. The electric business office supports the maintenance and repair of tram lines applied to railways in each region and includes a second data concentration device. The signal control office controls various signals required for train operation and includes a third data concentrating device. The communication network management office manages a communication network between the head office, branch offices, and each office and includes a fourth data concentration device. Herein, the first data concentrator to the fourth data concentrator perform at least one of collecting, analyzing, and reconstructing related data at each installed place, and transmitting the result to the outside through the at least one communication network.

Technical support system for railway electrical equipment according to the present invention, the diagnostic data generated from the on-site facilities for the maintenance of the system in real-time transmission to the unit of business, and accumulates and analyzes the transmitted data, maintenance personnel (managers) monitor By checking the status of equipment in real time, preventive maintenance plan and equipment operation can be efficiently performed.

In addition, by analyzing the data transmitted separately from each location, it is possible to accurately determine the state of the device with the resulting data, it is possible to determine and predict the trend of deterioration of the equipment, which can be confirmed anywhere in real-time railroad General and systematic management of electric power supply facilities as well as electric facilities will be possible.
