【摘要】 阐述了以单片机为核心的电磁继电器参数检测系统,通过串口通信,将采集到的参数上传到PC机上。并在此基础上,采用VC++进行人机交互界面的设计获得检测数据,并用MFC显示检测数据并使用ADO技术对SQL 2005数据库进行访问。在此系统中,实现了实验数据在数据库的存储、查询,删除和归档。方便了用户的使用,便于产品缺陷的查找,对提高产品质量起到了重要作用。更多还原

【Abstract】 An electromagnetic relay parameter detection system with a single chip microcomputer as its core was described.The parameters were collected and uploaded to PC by serial communication.Based on it,interactive interface were designed using VC++ to access the test data,which was showed on MFC.Meanwhile ADO technolo-gy was used to access database to SQL 2005.As a result,the test data was stored,queried,deleted,and filed in the database in the system.So it was convenient for users to find the product defects,and the quality of products was improved.更多还原
