摘　　要：针对企业对生产产品测试设备的应用软件使用的安全性和追溯性提出了越来越高的要求,开发了一款基于检测操作人员指纹识别验证的软件系统。测试设备上位机主机电脑使用基于图形化、模块化编程新模式的虚拟仪器LabVIEW作为开发设计平台,并使用.NET动态链接库为间接访问接口技术,实现了对微型指纹采集器的集成和二次研发应用,以及结合数据库技术实现了指纹信息数据的存储、查询和调用功能。实验证明:指纹识别验证系统运行非常安全、可靠、稳定,可集成到生产测试设备上,符合企业的生产要求。For the requirements of security and traceability of application software of test equipment of product in industry. The fingerprint of operator verification and validation system is designed and developed. The computer of test equipment uses LabVIEWwhich is virtual instrument based on graphical and modular development language platform and .NET dynamic link library interface technology. Realize the integration and acquisition in the second development with SDK using micro fingerprint acquisition instrument. And save、query and transfer the data with the database. The test result of verification and validation system shows thatthe system works security, reliable, steady and can be integrated to test equipment which meets the requirements with industry.
