高效处理器对于具有若干个驱动器和传感器的机电系统来说越来越重要了。为此,在一种具有多传感器的新型谷物硬度计设计中应用了32位低功耗的ARM微处理器。介绍了测试仪的结构,使用了嵌入式ARM微处理器完成了压力传感器的数据采集和交流伺服电机的位置控制。软件设计使用了基于Linux的QT语言,完成了在LCD上显示数据曲线以及实时的复杂数据处理。最后,给出了实验测量数据的图形结果,验证了本系统的可行性。
Efficient processors are increasingly important for electromechanical systems with several drivers and sensors. For this reason, 32-bit, low-power ARM microprocessors have been used in a new multi-sensor grain hardness design. Introduced the structure of the tester, used the embedded ARM microprocessor to complete the data acquisition of the pressure sensor and the position control of the AC servo motor. The software design uses a Linux-based QT language that completes the display of data curves on the LCD as well as real-time complex data processing. Finally, the graphical results of the experimental measurement data are given and the feasibility of the system is verified.
