Title:
TEMPORARY TRAIN SPEED RESTRICTION DELIVERY METHOD AND SYSTEM EMPLOYING TRACK CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/088447
Kind Code:
A1
Abstract:
A temporary train speed restriction delivery method and system employing a track circuit. The method comprises: S1, using a track circuit to receive temporary speed restriction information in a speed restriction zone and normal signal authorization information in the speed restriction zone, and sending the temporary speed restriction information and the normal signal authorization information to a track circuit information reading device; and S2, the track circuit information reading device receiving the temporary speed restriction information and the normal signal authorization information, demodulating the temporary speed restriction information and the normal signal authorization information to obtain demodulated temporary speed restriction information and demodulated normal signal authorization information, and sending the demodulated temporary speed restriction information and the demodulated normal signal authorization information to an on-board ATP sub-system of the train. Compared with existing wireless delivery, the method achieves real-time delivery of temporary speed restriction, does not depend on a wireless network coverage region and a wireless network communication quality, and expands the scope of trains that can be controlled by a temporary speed restriction command.
