Embodiment Construction

[0034] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Without loss of generality, this embodiment uses figure 1 The distance measuring principle of the secondary radar between the shown rear car and the front car is described in detail. The front and rear of the rail vehicle are respectively provided with a secondary radar to measure the vehicle (the rear car and the target vehicle (the same as the rear car). The vehicle distance between the front vehicle) in the running direction. Based on the ranging principle, the front secondary radar of the rear vehicle (the vehicle) is the main control terminal, which is used to send inquiry signals; The secondary radar is a non-master terminal, which is used to send a response signal. It should be understood that the specific i...

Abstract

The invention discloses a rail vehicle and train control management system and a control method for collision avoidance. A vehicle head and a vehicle tail of a rail vehicle are respectively provided with secondary radars to measure the distance between the rail vehicle and a target vehicle; the method for anti-collision auxiliary protection comprises the following steps of outputting a control instruction for adjusting the normal direction of an antenna of a secondary radar by taking the judgment condition that the secondary radar at the head of the vehicle does not receive a response signal after sending an inquiry signal, so antennas of the vehicle head secondary radar of the vehicle and the vehicle tail secondary radar of the target vehicle are in a signal transceiving interaction state; measuring the distance between the vehicle and the target vehicle; and outputting an alarm signal under the condition that the current vehicle distance reaches a preset vehicle distance threshold value. The method is advantaged in that potential safety hazards of train operation can be effectively avoided, and safe and reliable operation of the train is ensured.

Description

technical field [0001] The invention relates to the technical field of rail traffic control, in particular to a rail vehicle and train control management system, and a control method for collision avoidance. Background technique [0002] Usually, the operational safety of rail vehicles is protected by ATP full monitoring mode. When the ATP is cut off or fails, it will switch to the visual driving mode, and the speed limit is 40km / h. The safety of the vehicle in this state is generally protected by the driver. In this state, if the driver's sight is limited when encountering special road sections such as curves, there is a great potential safety hazard. [0003] Based on this problem, the prior art proposes an anti-collision early warning radar system, which uses secondary radar to form a monitoring redundant working mode, so as to improve the safety of rail transit operation. In the actual route, due to the different bending radii of the curves and the positions of the fro...
