在数字技术高速发展的今天，选择数字控制已经成为一种重要的探索和发展方向。本文选用了TI 公司生产的TMS320LF2407DSP 器件和AD 公司生产的ADXL203 加速度传感器，构建了一个信号采集处理系统，基于CCS 软件的开发流程，对系统进行了软件的设计，达到了很好的效果。采用硬件抗干扰措施较好地克服了模拟传输带来的干扰和噪声的影响。关键字: 信号处理；传感器；DSP；模块Abstract: In the rapid development of digit technology age, choosing digital control becomean important step and trend. This thesis chose the TMS320LF2407 of TI Corporation and theADXL203 accelerometer of AD Corporation, and constructed a signal processing system which realized the high speed data operation of the time domain and frequency range, which made the acceleration, the speed, and the displacement of real-time measurement quickly and reliably. Based on the CCS software development flow, the design of software was finished, and a good effect was obtained. Using the hardware antijamming measure overcame the disturbance and the noise influence well which the simulation transmission brought.Keywords: Signal Processing; Sensors; DSP; Module
