Title:
TRAIN POSITIONING SYSTEM AND POSITIONING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/092542
Kind Code:
A1
Abstract:
A train positioning system and positioning method. The positioning system comprises: a first axle-counting sensor (11), a first axle-counting outdoor device (12), a first axle-counting indoor device (13), a second axle-counting sensor (14), a second axle-counting outdoor device (15), a second axle-counting indoor device (16) and an axle-counting indoor main unit (7), wherein the first axle-counting outdoor device (12) is connected to the first axle-counting indoor device (13) by means of a first track circuit cable (01), and the second axle-counting outdoor device (15) is connected to the second axle-counting indoor device (16) by means of a second track circuit cable (02). A track circuit outdoor device is changed to connect a track circuit cable by means of an axle-counting outdoor device, and a track circuit indoor device is changed to connect the track circuit cable by means of an axle-counting indoor device, such that the track circuit cable can transmit a signal superimposed from a track circuit signal, an axle-counting signal and axle-counting power source signal, so as to realize co-cable transmission of axle-counting and a track circuit, such that an axle-counting device can still position a train when a track circuit has poor shunting or has a red-light strap caused by leakage.
