Temporary speed-restriction early warning system based on active tag and realization method thereof

Abstract

The invention relates to a temporary speed-restriction early warning system based on an active tag and a realization method thereof. The temporary speed-restriction early warning system comprises an active tag and a host machine of the temporary speed-restriction early-warning system, wherein the active tag is used for periodically broadcasting temporary speed-restriction information, and the host machine of the temporary speed-restriction early warning system is installed on a train; the tag information of the active tag comprises the arrangement of the active tag along the route direction of the train; the host machine of the temporary speed-restriction early warning system is provided with a reader operation interface, a current speed and position reading module, a main control module, a speed control module and a display module, wherein the reader operation interface reads the active tag; the main control module is used for positioning the active tag according to the read temporary speed-restriction information by combining the current speed and position information of the train corresponding to the temporary speed-restriction information to obtain the position of the active tag, and calculating a train speed control signal; the speed control module carries out train speed control on the train by a braking module; and the display module is used for prompting a train driver to carry out train speed control on the train. The invention adopts the active tag as a transmitting source, adopts the host machine of the temporary speed-restriction early warning system to read the temporary speed-restriction information and realizes temporary speed-restriction automatization.

Description

technical field [0001] The invention relates to the field of train temporary speed limit, in particular to a train temporary speed limit early warning system based on an active tag (RFID) and an implementation method thereof. Background technique [0002] At present, my country's railway management department uses temporary speed limit methods for trains by placing temporary signs or using walkie-talkies to notify drivers. These methods mainly rely on personnel notification or driver's lookout to obtain the temporary speed limit information of the road section, which has a great influence of human factors and has a very large potential safety hazard. Especially in the high-speed railway with fast train speed and many trains, it is completely managed by manpower, which has a large workload and is prone to errors, leading to traffic accidents. The temporary speed limit early warning device is an automatic early warning device used to prevent the train driver from not inputtin...
