Design and Implementation on flow meter of Locomotive braking system

Abstract

Introduced the theory designing and test researching of the flow transducer which is applied in Locomotive Brake System. By the characteristic and size requirements of Locomotive Braking System, V type internal cone flow transducer was adopted at first; second, the mechanism of the flow meter was designed; third, this article designed the software and hardware of a real-time data acquisition and display system based on the TMS320F2812DSP; finally, the flow meter was installed on the locomotive braking system and the experiment on the test stand was conducted. Experiment results show that the flow meter on the train braking system can meet the safety and reliability of the flow testing requirements. It can not only accurately measure wind flow, but also applied to the other flow measurement on the train brake system.
