摘　　要：对应用于机车制动系统的流量计进行了理论分析和试验研究。根据机车制动系统的特点,文中首先确定采用V型内锥式节流件作为该流量计的前端充风差压检测部件;然后根据机车制动机相关尺寸要求对流量计一次装置进行机械结构设计;接着采用TMS320F2812DSP芯片进行实时数据采集和显示系统的软、硬件设计;最后将该流量计安装于机车制动系统上,并在列车编组定置试验台上进行了试验。试验结果显示,该流量计不仅能对制动系统的充风流量进行准确测量,而且还可应用于列车制动系统其他流量测量的场合,同时也满足对列车制动系统工作安全性和可靠性的流量检测要求。This paper introduced the theory analysis and test research of the flow transducer,which is applied in locomotive braking system.By the characteristic of locomotive braking system,V type internal cone flow transducer was adopted at first;secondly,the mechanism of the flow meter was designed;thirdly,this article designed the software and hardware of a real-time data acquisition and display system based on the TMS320F2812 DSP;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 can not only accurately measure wind flow,but also apply to the other flow measurement on the train brake system.At the same time,the flow meter on the train braking system can meet the safety and reliability of the flow testing requirements.
