Application of Genetic Algorithm in Automatic Train Protection

Abstract

Automatic train protection plays an important role in high-speed railway, to implement this function, train braking mode curve must be derived. The programming logic of traditional braking mode curve arithmetic is complex, and its precision is not enough. To overcome these shortcomings, a braking mode curve arithmetic Based on curve fitting using genetic algorithm is proposed. Fit train braking characteristic data, use the kinematic formula for calculus calculation, and then braking distance-velocity function is derived, therefore braking mode curve can easily be obtained. Matlab is used for calculation. Compare the process and result of this new method with the traditional one, we can find this method is more simple and precise.
