摘要
介绍了一种无载测功系统的软、硬件设计及数学模型建立。主系统采用TI公司的MSP430F1232,实现了对瞬时速度的采集,结合最小二乘法,利用MCU的特点计算出发动机的瞬时加速度和瞬时功率。最后,得出相应的检测数据和误差分析。
This paper introduces the design of software and hardware of No_load Power Measuring System,and designed mathematical model.The master system is based on the MSP4301232 of TI.Instant Rotational Speed is measured in the test system,Instantaneous Acceleration and Instantaneous Power is caculated by using the feature of the MCU with the Least Squre Meathod.At last, Testing Data and ErrorAnalysis is measured.
