【摘要】 重载列车的制动性能是保证列车安全运行的关键问题。为了实现对64路重载列车制动试验的实时检测及处理,利用图形化编程软件LabVIEW和数据采集卡,设计了一个实时压力数据检测处理系统,系统利用Savitzky-Golay滤波器取得了良好的滤波效果。此外,系统还能对变送器进行自我校正、数据分析比较、报表生成和打印等功能。利用LabVIEW进行系统开发具有很强的灵活性,能较容易地实现系统的各项功能,并使系统具有很强扩展性。更多还原

【Abstract】 The performance of braking is the key to ensure the safety of thea heavy haul train. In order to realize the real-time data acquisition and processing of the heavy haul train braking test data,a real-time pressure data acquisition system is designed based on graphical programming software: LabVIEW and data acquisition card. Because of By the Savitzky-Golay filter,the system has a good performance in filtering. In addition this data acquisition system can make self-correction on the transmitter,data analysis,printing and generate reports. By using LabVIEW,the system has a strong flexibility,and can be more easy to realize all kinds of functions of the system,and can make the system to be more strong extensibility.更多还原
