A transmission data verifying apparatus of a detecting apparatus for real time railway safety of the present invention includes a data collecting system for collecting real time detecting data from a detecting apparatus of a railway facility. The data collection system collects data from a data transmission / reception platform installed in the detection device of each railway facility. As for the data collection system, the name of the inventor of the present invention filed on the same date is described in more detail in the specification of " Detection data collection system and program of railway safety detection device "

Each sensing device generates various signals depending on the conditions of the device, the conditions in the field, and the real-time fluctuations, and these signals are different for each manufacturer. Thus, the data collected in the data acquisition system is accumulated in units of voltage in different electrical signals for each sensing device. In the data collection system, a program for receiving and converting signals for each detection device of each manufacturer is built in.

Finally, it includes an integrated DB storage system that cumulatively manages the data collected after data analysis and verification in an integrated database (DB) for each detector and type. It is possible to perform verification of transmission data for each detecting device in the integrated DB storage system.

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

The railroad facilities newly installed in the field, for example, the mechanical communication, electric power facility, and signal facility detection device 8 are installed in each facility, for example, a real-time transmission device of train condition information, , Tunnel information devices, obstacle detection devices, line condition monitoring devices, and drag detection devices. Various signal data from these detecting devices 8 are collected through the data acquisition system 1 via the switch 5 and extracted, purified and loaded in the data refining system 2, .

Since the detecting device 8 is newly installed, it is required to perform preliminary inspection and specification verification. Therefore, it is possible to secure the reliability of the newly installed detection device immediately on the spot by analyzing and verifying the detection device and the specification verification corresponding to different signals for each detection device, In addition to being able to repair, it is possible to repair immediately.

In the past, a program for collecting, extracting, and converting signals of each detection device was installed in a remote control system, then the relevant detection device was installed in the field, the signal from the detection device installed was transmitted again to the remote control system, From the control system back to the site, notify the result of the preliminary inspection and the result of the specification verification. Then, in response to the situation, the newly installed detection device should be modified or reinstalled. This requires a lot of time and labor.

On the other hand, the data generated in the detection device installed in the past is also transmitted to the DDS data collecting device 6 via the switch 5 and sent to the control system 7. The control system verifies the generated data and notifies the vehicle control system or related persons based on the data. The person involved includes the driver who drives the vehicle, the railway line manages the line, the safety personnel, and the repairman. For example, when the data collected from the detection device of the drag and drop detection device is equal to or higher than that of the normal data, the vehicle under the train is dropped and the vehicle travels in a suspended state. At this time, the control system transmits the stop signal to the train so that the engineer can check the train condition after stopping the train, remove the dragged object, and then operate. Thus, it is possible to prevent damage to various facilities installed between the tracks.

2 is a conceptual diagram illustrating an example of a data collection system applied step by step.

First, EAI (Enterprise 　 Application 　 (Sniffing) method of detection data through the integration technique, all the applications associated with all the detection devices can be linked with each other organically to implement an environment in which necessary information can be centrally integrated, managed and used, In the point-to-point interface, there were substantial limitations in the number of applications, difficult maintenance, and a lot of cost and time loss when adding applications. However, in the interface where EAI was introduced, The required scalability can be guaranteed.

The transfer data of the detection device is copied from the core router 11 as a network device to the measurement server as the data collection system, and the data (binary file) collected by the measurement server is stored in the 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 an RDBMS (Relational Data Base Management System. Relational database management system), and the stored DB is confirmed as an interface using the FW 3.5 version of the electronic DB . When a hardware failure occurs during data transmission, the completion of data transmission is stored in the log between the measurement server and the branch server, and a retransmission function is implemented at the time of hardware failure recovery. In addition, the type and the attribute of the detection device are classified according to the attribute value of the header file of the transmission data through the branch server, and transmitted to the measurement server. The triggering is performed by the measurement server, Signal.

 An RDBMS is a computer software used for adding, editing, querying, analyzing, and summarizing attributes contained in a database (DB). It is a system for systematically storing, managing, and managing data used in a detection device.

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

3 is an exemplary table illustrating the log file DB switching. Here, the transmission data (binary file) collected in real time is converted into a hexadecimal log file and the data is extracted and stored in the designed RDBMS. 3 (a) shows a hexadecimal log file and b is a table showing DB stored data.

In particular, the warning contents can be displayed as a popup (warning window) in case of trouble or abnormality.

To verify the transmission / reception data of each detection device, the network of each detection device is interlocked with the high performance core router 11 of the verification system. The core router 11 is configured to be able to transmit the selected data of each detection device to the measurement server 14, and two measurement servers are preferably structured. One is a first measurement server for receiving detection data of a new detection device and a second measurement server for receiving detection data of an existing railway safety detection device. For the flexibility of data verification servers, we introduce the Nutanix system, which uses HCI (Hyper Converged Infrastructure) technology, in the integrated virtual server system. Through this, it is possible to adjust the number of virtual servers according to the change of the detection data type, the increase of the data, and the I / O performance to the service network.

CCTV image data is stored in a separate image storage storage for CCTV image application devices such as obstacle monitoring devices. Transmission data monitoring and reporting of detection devices The PC is separated into the monitoring PC network, and the monitoring PC is configured by configuring a management PC for Nutanix integrated virtual server management.
