摘要
对表面粗糙度检查记录仪进行虚拟仪器化改造,确定模块化的改造方案.设计调试测量电路;选择USB采集卡实现A/D转换和计算机接口,并实现计算机监控零位与测量控制;根据表面粗糙度最新国家标准中各参数的定义和各项预实现功能,利用VB6.0软件平台构建测量软件;对整体测量系统进行调试和测量误差测试,表明改造后的表面粗糙度检测仪可方便地进行各项指标的检测.
A virtual instrument for surface roughness tester is implemented. The program for this VI is developed, and the measuring circuit is designed and debugged. A A/D converter and the computer interface using USB acquisition card are realized. Monitoring the zero posi- tion and the measuring control using computer are achieved. According to the national stand- ards for definition of parameters in surface roughness and pre-implementation function, the software platform is set up using the VB6. 0. Finally, the proccess for debugging the whole measuring system and the error testing is also introduced.
