Description

TECHNICAL FIELD [0001] The present invention relates to an automatic train protection stop (ATPS) device. Particularly, the present invention relates to the ATPS having both the functions of an automatic train protection (ATP) and an automatic train stop (ATS) by adding a K-Balise, on the ground, which is capable of transmitting ground information using a small air-gap data communication and a ground information memory pack on a train. BACKGROUND ART [0002] Typically, a device transmitting ground information for an automatic train stop is called Balise. The Balise is a device for transmitting, using data communication, ground information such as ground operation conditions, distance and position of the beacon, and a target speed from a ground equipment to an on-board equipment. [0003] The K-Balise adapted to the present invention as a part of the current ATP is a Balise integrating a beacon, a tag (Transponder or Loop Coil), card or terminal. Particularly, it includes a Euro Balise ...

AI Technical Summary

Benefits of technology

[0017] According to the present invention, it is possible to implement the ATP and ATS functions using the data communication method. Especially, the on-board equipment of the ATP system directs the operation limit speed, reduce the operation speed below the limit speed or activates emergency brake when the operation speed exceeds the limit speed, and then releases the constant brake or brake mode when the speed is recovered to be lower than the limit speed. The ATPS of the present invention has a function providing the on-board operation information and an auxiliary operation function, a self-testing function for testing the system before the train starting, and a storage function for recording and maintaining the operation records so as to efficiently perform the speed control per tract section according to the ATS frequency.

[0018] Since the ATPS of the present invention utilizes an electric source-free data communication method, it is possible to secure the high security and reliability during the high-speed communication in every frequency bandwidths.

[0019] Also, in the present invention it is possible to increase the utilization of the rail by increasing the efficiency of the distance-to-go control with the ground information, and furthermore to increase the stability and accuracy of the train control by checking the positions of the train in various view points using the beacon, K-Balise, speed detector, or / and GPS receiver. Particularly, it is possible to transmitting the massive data by selecting the frequencies according to the amount of the information and to improve the stability by protecting the no reaction and malfunctioning.

Problems solved by technology

The conventional narrow space communication has drawbacks in that the communication speed and distance is dependant on the using frequency, especially, the communication speed is very low at a low frequency.

Even though the transponder, Balise, or tag adapted to the ATP for controlling the train requires the high reliability and security, they do not show the enough performance in the communication speed, reliability, and security in the conventional ATS frequency bandwidth.

Also, the communication speed is limited even with the RF-ID, such that it is limited for using with the applications requiring massive data processing.

Accordingly, the conventional technique is limited to be used with the Balise requiring high reliability and security.
