Abstract

The invention discloses a vehicle collision prevention early-warning radar system for rail transit, and the system comprises a first radar main unit which is used for active range finding and inquiry; a second radar main unit which is connected with the first radar main unit and is used for range finding response. When the first radar main unit has a fault, the second radar main unit takes charge of the active range finding and inquiry functions of the first radar main unit. When the second radar main unit has a fault, the first radar main unit takes charge of the range finding response function of the second radar main unit. The system has a working mode of double-unit mutual monitoring redundancy, and improves the safety and efficiency of rail transit.

Description

technical field

[0001] The invention relates to rail transit vehicle operation safety assurance technology, in particular to a collision avoidance and early warning radar system for rail transit vehicles. Background technique

[0002] At present, the driving safety of high, large and medium traffic systems in rail transit mainly depends on the automatic train protection system (ATP) in the automatic train control system (ATC), while the sub-medium and low traffic systems all rely on the driver to drive. . For example, subways and light rail rely on the ATP system, and modern trams rely on drivers to drive. When the ATP system fails or degrades, the vehicle is in an abnormal working state, and its driving safety depends on the telephone blocking measures. In this state, the driver drives manually according to the command of the dispatcher. At this time, if there are special road sections such as curves and uphill and downhill, the driver's vision is limited, and there is a...
