The data server analyzes this information, stores it in the integrated DB of the DB server, and transmits the information to the comprehensive status screen of the integrated operation management software operated on the web server to express the failure condition.

The integrated operation management (signal field) software according to an embodiment of the present invention is developed based on the web in a Windows environment, and services are provided through a web browser (eg, Internet Explorer, etc.).

In addition, fault and alarm information is displayed through the integrated operation management (signal field) screen.

Hereinafter will be described in detail with respect to the valis integrated monitoring method for the implementation of the present invention.

According to an embodiment of the present invention, in the case of monitoring the operation state of the vallis 10 at a remote location when the train is operating, when the train moves through the area where the valise 10 is installed, the train antenna installed on the vehicle is the valise 10 It transmits a 27.095 MHz frequency signal to the ground to power it.

In addition, the telegram signal is transmitted to the vehicle at a bit rate of 564 kbit / s by dividing the power from the supplied valis 10 into 3.95 MHz representing "0" and 4.234 MHz representing "1" as a bit signal.

Subsequently, the information of the variable ballis 10 storing the signal information transmitted from the LEU 40 is collected by using the loop receiving antenna 58 installed at the bottom of the ballis 10 to collect the signal information transmitted to the vehicle and post electricity. It is displayed on the user console of the facility technical support system (60, 65, 70).

On the other hand, in the case of monitoring the operation status of the vallis 10 at a remote location when the train is not operating, the monitoring start signal is checked in order to check whether the vallis 10 is normally operated by the electrical equipment technical support systems 60, 65, 70. Is transmitted to the optical conversion unit 52 of the ATP function monitoring unit 50 through the railway optical communication network 65.

And the monitoring start signal, which is the Ethernet packet converted by the optical conversion unit 52, is transmitted to the control unit 54-3 of the ATP function monitoring unit 50 via the N PORT 51 having the RS-232 interface function.

It receives a corresponding command from the core processor of the control unit 54-3 of the ATP function monitoring unit 50 and generates a telepowering signal from the telepowering AMP module of the transmitter to loop CW (Continuous Wave) waves. It transmits to the transmitting antenna 57 and transmits again to the balis 10 in CW.

The ballis 10 receives power by receiving a 27.095 MHz telepowering signal, which is CW, and receives the air gap from the telegram information separated into 3.95 MHz representing "0" and 4.234 MHz representing "1" as a bit signal. It transmits to the loop receiving antenna 58 through.

The loop receiving antenna 58 installed at the bottom of the ballis 10 collects a telegram signal, which is Up-link Data transmitted to the air gap.

The telegram signal collected through the loop reception antenna 58 is received by the telegram reception module, which is a reception unit of the ATP function monitoring unit 50.

The ATP function monitoring unit 50 FSK demodulates the collected telegram signal, demodulates the telegram signal transmitted to the vehicle, and transmits the telegram signal to the N port through the RS-232 interface. .

In N PORT, the telegram signal is converted to TCP / IP and transmitted back to the electrical equipment technical support system (60, 65, 70) through the optical fiber network (65) through the optical converter.

On the other hand, in the case of monitoring the operating state of the vallis 10 at a remote location when the train is running, when the train proceeds to the area where the valise 10 is installed, the train antenna installed on the vehicle is used to supply power to the valise 10 It transmits a 27.095 MHz frequency signal to the ground.

The telegram signal is transmitted on the vehicle at a bit rate of 564 kbit / s by dividing the power from the supplied valis 10 into 3.95 MHz representing "0" and 4.234 MHz representing "1" as a bit signal.

Electric equipment technology by collecting the signal information transmitted to the vehicle by using the loop receiving antenna 58 installed at the lower part of the ballis 10, the information of the variable ballis 10 storing the signal information transmitted from the LEU 40 It is displayed on the user console of the support systems 60, 65, and 70.
