To send). The second TFM 30-2 controls the train diverter of the train branch point 2 under the control of the second SSI 10-2, and transmits a control result and state to the second SSI 10-2.

A first station data transceiver 40 is configured on the first station side to perform data communication between the SSI 10 and the TFM 20 for each of the networks, and between the second station or the first station and the second station at a distance. Perform data communication with the TFM 30 configured in the interval of.

The second station data transceiver 50 is installed at a distance from the train junction 1 and performs data communication between the SSI 10 and the TFM 30 via the first station data transceiver 40.

Optical data communication is performed between the first station data transceiver 40 and the second station data transceiver 50.

Specifically, the first station data transceiver 40 includes first converters 41-1 and 42-1 corresponding to the first SSI 10-1 and the first TFM 20-1 for the first network, Second converters 41-2 and 42-2 corresponding to the second SSI 10-2 and the second TMF 20-2 for the second network, and the TFM 30-1 and the TFM 30-2, respectively. A multiplexer 44 comprising a first optical converter 45-1, a second optical converter 45-2, and a clock source generator 46 for generating and outputting a clock source for data optical communication with each other). And a first divider 43-1 for interfacing data transmitted and received between the first converter 41-1, the first converter 41-2, and the first optical converter 45-1. A second divider 43-2 for interfacing data transmitted and received between the converter 42-1, the second converter 42-2 and the second optical converter 45-2, and the clock source; The first converters 41-1 and 42-1 and the second converters 41-2 and 42-2 generate and output clocks necessary for data transmission and reception. Consists of Luck splitter 47. The

The first converters 41-1 and 42-1 are data line termination devices (DCEs), which transmit and receive data by a clock input from the clock divider 47, and are input from the first SSI 10-1. Converts data according to the G.703 protocol into data according to the V.35 protocol, outputs the data to the first divider 43-1, and inputs the data according to the V.35 protocol input from the first divider 43-1. The data is converted into data according to the .703 protocol and output to the first SSI 10-1.

The second converters 41-2 and 42-2 are data line termination devices (DCEs), which transmit and receive data by a clock input from the clock divider 47, and are input from the second SSI 10-2. Converts the data according to the G.703 protocol into data according to the V.35 protocol, outputs the data to the second distributor 43-2, and inputs the data according to the V.35 protocol inputted from the second distributor 43-2. The data is converted into data according to the .703 protocol and output to the second SSI 10-2.

The first converters 41-1 and 42-1 and the second converters 41-2 and 42-2 operate only in the subordinate mode and do not operate in the control mode. The dependent mode mode is a mode having no clock providing function, and the control mode means a mode having a clock providing function. That is, the first converters 41-1 and 42-1 cannot operate in the Contradirection mode (main / dependent clock supply method) defined in G.703. Thus, as shown in FIG. 2, the first converters 41-1 and 42-1 operate in a centralized mode (external clock supply method).

In FIG. 2, the multiplexer 44 includes only the first optical converter 45-1, the second optical converter 45-2, and the clock source generator 46, but also inserts a plurality of cards.

In addition, since the first and second converters do not operate in a control mode, the data transceiver of the conventional train branch system does not operate the clock divider to synchronize the main data transceiver connected to the SSI and the data transmission / reception period at a remote distance. Since there is a need to use a separate clock source generator and clock divider has a problem.

In addition, since two clock dividers are used, a conventional data transceiver has an error in clocks generated by two clock dividers, and a data transmission / reception error occurs when the clock error is out of a specific error range.

In addition, the multiplexer of the data transceiver of the conventional train branch system transmits and receives not only data of the train branch system but also data between other systems (ATC), and the multiplexer checks whether a card is inserted into the slots and checks the state of data transmission and reception. As a result, the data transfer rate was delayed.

In addition, it is not possible to check the errors of each configuration of the data transmission and reception device of the conventional train branch system, so a separate error checking device should be provided outside, and the cost of installing a separate error checking device increases, and error checking Even if a device is provided, there is a problem that the state of the individual components inside is unknown.

If the data frame and the redundancy frame do not match in step 719, the controller 310 proceeds to step 727 described above, and if it matches, the control unit 310 proceeds to step 721.

The controller 310 proceeds to step 727 to perform the same process as described above. However, the content of the alert notification message that is generated is different.

On the other hand, the controller 310 proceeds to step 721 and compares each field of the frame with predefined field values. In particular, the state value of the state field of the configuration in which the data is transmitted in the frame is compared with a predefined state value.

After the comparison, the control unit 310 determines whether the test result is normal in step 727, and if not normal, proceeds to step 727 to generate a warning notification message for a part that is not normal and outputs it to the Ethernet communication unit 380.

In contrast, if normal, the controller 310 proceeds to step 725 and generates a normal notification message for notifying that the state of each component is normal and outputs it to the Ethernet communication unit 380. After outputting the normal notification message, the controller 310 controls the configuration input of the data to output the buffered data.

The data error and the device status check as described above may be set to check at regular intervals, or may be made by an administrator through a network monitoring and control system connected to the Ethernet network.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.

The data transceiver of the present invention as described above has the advantage that the converter can operate in both the subordinate mode and the control mode.

In addition, the data transceiver of the present invention can operate in both slave mode and control mode, so that only the first reverse data transceiver adjacent to the SSI has an internal or external clock to synchronize both the first reverse data transceiver and the second reverse data transceiver. Since it is possible to fit the first station data transceiver and the second station data transceiver each has the advantage that does not generate a data transmission and reception error due to the error of the clock, such as when having a clock.

In addition, since two clock dividers are used, a conventional data transceiver has an error in clocks generated by two clock dividers, and a data transmission / reception error occurs when the clock error is out of a specific error range.

In addition, the present invention uses the optical converter only for the train branch system has an effect that can transmit data at a faster data transmission rate than the data transmission and reception apparatus of the conventional thermal branch system.

In addition, the present invention can reduce the cost due to the installation of a separate error check device because it is not necessary to provide a separate error check device by performing the error check by configuring the above-described data transceiver on-board Has the advantage of knowing the state of the individual components therein.
