Transmission data verification device of the detection device for real-time railroad safety of the present invention includes a data collection unit for collecting the real-time detection data from the detection device of the railway facility. The data collection unit collects data from the data transmission and reception platform installed in the detection device of each railway facility. As for the data collection unit, the applicant's invention, which is filed on the same day, is described in more detail in the specification "Detect data collection system and program of railroad safety detecting apparatus" and will be incorporated herein.

Each detection device generates various signals according to the conditions of the device, conditions in the field, and real-time changes, and these signals are different for each manufacturer. Therefore, the data collected by the data collector is accumulated in units of voltage as different electrical signals for each detection device. The data collection unit has a built-in program for receiving and converting signals for each detection device of each manufacturer. When a new detection device is installed in the field, a data collection unit receives and converts a signal for a new detection device in advance. We install in department. New detectors can be installed on-site and converted from the signals from them into standard or custom data formats.

And a data purification unit for extracting, purifying and loading data accumulated in the data collection unit. The data refiner may be configured as an extended metadata registry (XMDR) server for real-time data extraction and purification, and the XMDR server may include a Query Manager, a Transaction Manager, an XMDR, a Data Manager, and a Monitoring & Log Manager.

 It includes a data analysis verification unit for verifying the abnormality by checking the promised transmission cycle, format, etc. data from the data purification unit. The data analysis verification unit includes various programs that can visualize the data and verify the results.

Finally, the integrated DB storage unit for accumulating and managing the data collected after the data analysis and verification in the integrated database (DB) for each detection device and type. In the integrated DB storage unit, the transmission data of each detection device may be verified.

First, the present invention will be described with reference to a conceptual diagram of the verification apparatus of FIG. 1.

The railroad facilities newly installed on the site, for example, the detection device 8 of the mechanical communication, the power facility, and the signal facility are installed at each facility, for example, the train status information real-time transmission device, the train access confirmation device. , Tunnel information device, obstacle detection device, track condition monitoring device, drag detection device. The various signal data from these detection devices 8 are collected via the data collection unit 1 through the switch 5, extracted, purified and loaded in the data purification unit 2, and the data is analyzed by the data analysis verification unit 3. Analyze and verify

Since the detection device 8 is newly installed, it is necessary to perform preliminary inspection and specification verification. Therefore, since the above-described systems are put into the field and carried out, the inspection and preliminary inspection of the detection device can be analyzed and verified in response to different signals for each detection device, thereby ensuring the reliability of the newly installed detection device in the field. Not only that, but in case of an abnormality, it can be repaired immediately.

In the past, the remote controller installed a program that collects, extracts, and converts signals from each detector, then installs the detector in the field, and sends the signals from the installed detectors back to the remote controller. The control department is notified of the abnormality in the preliminary inspection and the result of the standard verification. The site must then be modified or re-installed in response to the newly installed detection device. This takes a lot of time and labor.

On the other hand, the data generated by the existing detection apparatus is also sent to the control unit 7 via the switch 5 to the DDS data collection unit 6. The control unit verifies the generated data and notifies the vehicle control system or related parties based on the generated data. Participants include drivers who drive vehicles, trackmen who manage tracks, safety personnel, and repairmen. For example, when the data collected from the detection device of the drag detection device is abnormal in comparison with the usual data, the vehicle is a vehicle that runs in a suspended state when the accessories under the running train are dropped. At this time, the control unit transmits a stop signal transmission to the train so that the engineer can check the train state after the train stops and remove the dragged object to operate. As a result, it is possible to prevent breakage of various facilities installed between tracks.

In the point-to-point interface, there was a practical limit on the number of applications, difficulty in maintenance, and enormous cost and time loss when adding the application.In the interface using the EAI, only the adapter was introduced when the detection device was introduced. Easy scalability required can be guaranteed.

The binary data is copied from the core router 11, which is a network device, to the measurement server as a data collection unit, and the data (binary file) collected by the measurement server is stored in a DB. Here, the transmission information in the raw data file is extracted, and the extracted information is stored in an interface-designed DB in the form of relational database management (relational database data management system relational database), and the stored database is identified by the interface applying the FW 3.5 version. . When hardware failure occurs during data transmission, it compares the completion of data transmission to the log between the measurement server and the branch server, and implements the retransmission function in the event of hardware failure recovery. In addition, the branching server classifies the types and attributes of the detection device according to the property value of the header file of the transmitted data and transmits them to the measurement server.The triggering is automatically stored in the DB of the monitoring server after the purification / conversion process in the measurement server. Generate a signal.

 RDBMS is a computer software used for adding, editing, querying, analyzing, and summarizing attributes included in a database, and is a system for systematically storing, managing, and managing data used in a detection device.

The log server 12 collects the logs generated by the router 11, and the collected logs are sent to the EAI sniffing data branch server 13 to execute Agent Mon and, in the case of a new log file, to run Agent Mon again. It is transmitted to the measurement server which is the EAI log management server 14 via TCP communication. The EAI log management server 14 executes log collection, and after the log collection is completed, executes the log file DB (BlOB, binary large object) according to the presence or absence of a log file, and performs BIOB logs. The BIOB log data is transmitted to the monitoring server 15 through a DB trigger to execute Agent Mon to visually display the data on the monitor.
