摘要: 开发一种基于USB总线的智能便携式沥青路面检测系统。根据沥青材料的红外辐射特性,采用红外热电偶温度传感器和容栅位移传感器对沥青路面的摊铺温度和厚度进行测量。由传感器输出与检测信号成正比的电压信号,通过以单片机AT89C52为核心的扩展系统实现数据的A/D转换、存储、显示及传输。利用USB总线将数据上传至上位机PC或掌上电脑,实现检测数据的归档和分析并完成曲线绘制。

Abstract: This paper develops a novel portable asphalt pavement test system with USB bus. According to the infrared radiation characteristics of asphalt material, infrared thermocouple senor is applied to testing paving temperature of asphalt by non-touched infrared ray, while capacitive fence displacement senor based on principle of relative areas change is applied to test paving thickness. The output of senor is sent to the expend system with the control core of single chip microcomputer AT89C52, which realizes A/D conversion, data storage, data display and data transmission. The application software installed in the notebook PC makes a fast processing and analysis of the data transferred by USB bus.
