研制一套基于LabVIEW的三针自动校准系统。由激光测径仪对三针进行非接触测量，引入脚踏开关，控制激光测径仪的测量过程。引入“簇”元素，将一组三针的测量数据自动封装，便于后续按三针规格自动排序。通过ActiveX技术，自动生成电子原始记录，通过LIMS系统，一键生成报告证书。实际运行表明：该系统可提高检测效率、免除人为误差及降低工作强度。“,”An automatic calibration system for cylindrical measuring pins based on LabVIEW was developed. A laser micrometer was used to measure the three pins in a non-contact way. A footswitch was used to control the measurement process of the laser micrometer. The measurement data from one group of three pins was packed up in a “cluster”, which was convenient for subsequent automatic sorting according to the specifications of the pins. The electronic original record was automatically generated based on the ActiveX technique and the report was generated after just one click by a LIMS system. The actual operation showed that the system can improve detection efficiency, avoid human errors, and reduce workloads. The system can be widely used in various calibration and testing laboratories.
