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.
