嵌入式智能动平衡测试系统及其滤波器设计

Embedded Intellingent Dynamic Balance Testing System and Its Digital Filter Designing

针对动平衡测试中要求实时处理大量信息 ,而现有的基于单独微控制器的智能动平衡测试仪和动平衡机控制箱不易满足该要求的情况 ,提出了一种将DS———微控制器组对直接应用于智能动平衡仪中子系统设计的方法。介绍了这种方法实现及其数字滤波器的设计 ,该方法是将DSP与微控制器 (即单片机 )组成一对主从控制系统 ,微控制器作为主控器完成全局控制 ,而利用DSP的快速运算特点来实现动平衡的数字滤波、FFT等。根据该方法所开发的系统可以在动平衡测试中作更多的时域、频域项分析。

A lot of information needs processing in time in dynamic balance testing, but the current intelligent dynamic balance instruments and the controlling box of dynamic balance machines made up ofsinglemicrocontroller do not meet the request.A method isgioen that the DSP-Microcontroller will be useddiredtlyinthe system of the intelligent dynamic balance instrumentby using embedded design technique. A principal and subordinate control system compose of DSP and microcontroller. The Microcontroller the system as a principal controller and the DSP implements digital filtering and FFT in dynamic balanc by means of its fast operation. The system develoyed according tothe method can do more analysisin time areaand frequency area.
