Abstract :
To solve pneumatic pipe leakage of freight train, a base flow detection algorithm is proposed. Firstly principle of pneumatic brake system is analysed, workflow and fault characteristics of pneumatic pipe leakage are researched. Then detection process of pneumatic pipe leakage is designed with maintenance requirement. At last a base flow leakage diagnosis algorithm is discussed and verified. Experiment datas indicate this diagnosis technology ensure the dynamic operating conditions and security of the algorithm reliability with stability.
