Abstract

The embodiment of the present invention provides a method and system for monitoring trains in subway depots based on UWB. The distance information of the head and the distance of the tail determined based on UWB technology are obtained respectively, and the position information of the head is determined according to the distance information of the head. The tail distance information determines the rear position information, and finally, based on the front position information and the rear position information, the occupied range of the target train on the train track is determined to realize the positioning of the target train. The entire positioning process does not introduce third-party equipment data. Through the two-dimensional precise ranging capability of UWB and the principle of triangulation positioning, the precise positioning of the front and rear of the target train is realized, and then the occupancy of the target train on the train track is determined. In the depot, it can ensure that the train stop position is accurate, and can further judge whether the target train is complete, so as to ensure the complete formation of the target train.

Description

technical field

[0001] The invention relates to the technical field of rail transit, and more specifically, to a method and system for monitoring trains in subway depots based on UWB. Background technique

[0002] With the improvement of living standards and the increase in the demand for train transportation, it is very important to locate the train to determine the position of the train for train scheduling and accident prevention.

[0003] At present, the positioning of the train is usually realized by the interval positioning method, specifically, the beacon positioning is adopted, and the beacon is installed along the train running track to reflect the physical sign of the absolute position of the train running track. The beacon is similar to a non-contact integrated circuit (Integrated Circuit, IC) card. When the train passes the beacon, the electromagnetic wave emitted by the vehicle antenna stimulates the beacon to work, and transmits the absolute position informatio...
