导引头测试设备自动检定系统研究
|
摘要
针对导引头测试设备目前检定方式效率低、过程繁琐、人为错误无法避免等问题,基于虚拟仪器技术和数据库技术,设计一套自动计量检定系统。系统使用Labwindows/CVI作为软件开发平台,通过灵活运用多线程技术,使得软件运行流畅并具有较高运行效率;使用VISA库函数作为仪器I/O驱动,使得软件在I/O层实现统一;使用SCPI语言作为仪器控制方式,加强了测控程序的通用性;使用Labwindows SQL工具包访问ODBC数据库,实现数据的存储和查询。经检验,该系统运行稳定可靠,可用于设备的自动检定。
Aiming at the problems of low efficiency,complicated process and human errors,an automatic test verification system based on virtual instrument technology and database technology is designed for the current seeker test equipment. The system uses Labwindows/CVI as a software development platform,which makes the software run smoothly and has high operational efficiency through the flexible use of multi-thread technology. The use of the VISA library function as I/O driver enables the software to be unified at the I/O layer. SCPI language as the instrument control mode strengthens the versatility of the measuring and controlling procedure. Labwindows SQL tool kit is used to access the ODBC database,which realizes the data storage and the inquiry. The test results show that the operation of the system is stable and reliable,and can be used for automatic verification of equipment.
