摘　　要：文章介绍了数字信号处理器(DSP)和液晶模块在便携式路基压实度测定仪中的应用。介绍了用DSP进行数字信号处理的软件设计以及DSP与液晶模块VP12864T(控制器为T6963C)的接口技术。DSP的应用使得该仪器脱离计算机运行,体积大大减小,功耗明显降低,便于携带,方便野外操作;液晶模块的应用使得仪器能够直观的显示信号波形及其对应的压实度值。This text has introduced the application of DSP and liquid crystal module in the highway subgrade compaction degree measure device. It has introduced the software of DSP and the joint technology with LCD screen VP12864T . This device runs without computer with DSP , the volume and consumption have minished clearly, so it is easy to carry, to operate in open country. The application of liquid crystal module, makinu the instrument can visually show signal waveformand the corresponding degree value.
