【摘要】 基于NI数据采集卡及调理模块,配合发动机各关键位置的传感器,采用LabVIEW软件编写采集程序和串口通信程序,开发了双燃料发动机实时监控测试系统。利用标准信号发生器等设备校准所开发的测试系统,并在双燃料发动机试验台上获取了部分测试点的实时状态参数,验证了所设计开发的测试系统的精确度。更多还原

【Abstract】 Based on the NI data acquisition (DAQ) card and SCXI module together with the sensors mounted on the engine,the real-time monitoring and test system was developed for dual-fuel engines through the acquisition programs and serial communication programs designed by LabVIEW.The designed test system was calibrated by using the standard signal generator and then its accuracy was verified on the experimental bed by comparing with the real-time parameters of the dual-fuel engine.更多还原
