Abstract

The present invention relates to an apparatus and method for processing an intermittent information in railway, the method comprising determining that data of a prescribed first length is received in first and second buffers; reading and storing the data of the first length in the first and second buffers; determining that data of a prescribed second length is received in the first and second buffers; reading and storing the data of the second length in the first and second buffers; and generating a final data by combining the data of the first length and the data of the second length.

First claim

What is claimed is:

1. A method for processing intermittent information in railway, the method comprising:
receiving, at a first buffer, first data from a first loop arranged in the railway;
receiving, at a second buffer, second data from a second loop arranged in the railway;
waiting, for a predetermined time, when length of any of the first data or the second data is longer than a first length;
continuing the receiving at the first buffer and the second buffer during the waiting for the predetermined time;
reading and storing at the first buffer and the second buffer, respectively, the first data and the second data, when both the first data and the second data are longer than the first length;
determining that third data and fourth data, each having a length longer than a second length, are respectively received at the first buffer and the second buffer;
reading and storing at the first buffer and the second buffer, respectively, the third data and the fourth data, when both the third data and the fourth data are longer than the second length; and
generating, by a processor, final data by combining the first data, the second data, the third data and the fourth data.

2. The method of claim 1 , further comprising:
clearing the first buffer when the first data is longer than the first length and the second data is not longer than the first length; and
clearing the second buffer when the second data is longer than the first length and the first data is not longer than the first length.

3. The method of claim 1 , wherein the first length corresponds to a length of a start-notifying data.

4. The method of claim 3 , wherein the second length corresponds to a length of a data including information.

5. The method of claim 4 , wherein the generating the final data includes aligning the start-notifying data at a forefront and aligning the data including the information after the start-notifying data.

6. The method of claim 1 , further comprising:
transmitting the final data to on-board equipment in a train.

7. An apparatus for processing intermittent information in railway, the apparatus comprising:
a first antenna configured to receive intermittent information from a first loop arranged on the railway;
a second antenna configured to receive intermittent information from a second loop arranged on the railway;
a receiver configured to convert a message of an analog type signal received from the first antenna or the second antenna to a message of digital data, and
a ATC (Automatic Train Control) on-board equipment configured to analyze the message of digital data,
wherein the ATC on-board equipment includes:
a first buffer configured to store intermittent first data from the first loop;
a second buffer configured to store intermittent second data from the second loop; and
a processor configured to generate a final data by combining the first data and the second data received from the first and second buffers, and
wherein the processor is further configured to:
determine that the first data and the second data, each having a length longer than a first length, are respectively received at the first buffer and the second buffer;
read and store at the first buffer and the second buffer, respectively, the first data and the second data, when both the first data and the second data are longer than the first length;
determine that third data and fourth data, each having a length longer than a second length, are respectively received at the first buffer and the second buffer;
read and store at the first buffer and the second buffer, respectively, the third data and the fourth data, when both the third data and the fourth data are longer than the second length; and
generate the final data by combining the first data, the second data, the third data and the fourth data.

8. The apparatus of claim 7 , wherein the first and second buffers include a ring buffer.

9. The apparatus of claim 7 , wherein the processor is further configured to wait, for a predetermined time, when length of any of the first data or the second data is longer than a first length.

10. The apparatus of claim 9 , wherein the processor is further configured to
clear the first buffer when the first data is longer than the first length and the second data is not longer than the first length; and
clear the second buffer when the second data is longer than the first length and the first data is not longer than the first length.

11. The apparatus of claim 7 , wherein the first length corresponds to a length of a start-notifying data.

12. The apparatus of claim 11 , wherein the second length corresponds to a length of a data including information.

13. The apparatus of claim 12 , wherein the processor is configured to align the start-notifying data at a forefront and align the data including the information after the start-notifying data.

14. The apparatus of claim 7 ,
wherein the first antenna is configured to receive the first data transmitted from the first loop; and
wherein the second antenna is configured to receive the second data transmitted from the second loop.

15. The apparatus of claim 14 , further comprising:
a transmitter configured to convert the first data received from the first antenna and the second data received from the second antenna to a second digital signal, and transmit the second digital data to the first and second buffers.
