Embodiment Construction

[0041] The following is attached Figure 1-6 The present invention is described in further detail.

[0042] The train dynamic tracking safety protection model proposed by the present invention is based on Newtonian dynamics, researches and analyzes the safety tracking interval of the train under the relative speed tracking mode, and proposes a dynamic safety braking model that can directly reflect the relationship between braking conditions and vehicle speed . And combined with the cooperative collision avoidance mechanism and threat monitoring mechanism to ensure its safety.

[0043] The invention proposes a safety protection model including a dynamic safety braking model, a cooperative collision avoidance mechanism and a threat monitoring mechanism. The schematic diagram of the implementation principle of the security control algorithm is as follows: figure 1 As shown, the dynamic safety braking module, cooperative collision avoidance module and threat monitoring module a...

Abstract

The invention relates to a train dynamic tracing safety protection model comprising the specific step 1 of establishing a dynamic safety braking model; the step 2 of establishing a cooperative collision avoidance mechanism used for avoiding occurrence of continuous collision accidents; the step 3 of establishing a threat monitoring mechanism which serves as a complementary mechanism in case of failure of the cooperative collision avoidance mechanism; the step 4 of forming the train dynamic tracing safety protection model through combined action of the dynamic safety braking model, the cooperative collision avoidance mechanism and the threat monitoring mechanism, and ensuring that trains are not rear-ended under the condition of normal operation. The continuous collision accidents can be further avoided even though a preceding train is collided due to external factors.

Description

technical field [0001] The invention belongs to the technical field of rail transit operation control, and relates to a train dynamic tracking safety protection model. Background technique [0002] my country's urban rail transit industry is in a rapid and sound development stage, but the pressure on rail transit operations in some first-tier cities is becoming increasingly severe. In order to alleviate the operating pressure, it is necessary to effectively improve the driving efficiency under the premise of ensuring safety. [0003] At present, the train operation control system adopted in the field of urban rail transit in my country is the communication-based train control system (CBTC). track. [0004] The tracking target point of the mobile block method is the tail of the preceding train, and the calculation point for the following train to start braking from the highest speed is determined according to the target distance, target speed and performance of the train its...
