串口通信是实现显微硬度计微机测量的关键。本文重点研究了在VC++平台下利用MSComm控件开发微机与显微硬度计串口通信实现实时数据显示和数据处理的原理,以及利用SQL Server和VC++的ADO数据库访问技术开发数据管理系统的过程与方法。所开发的测量软件界面友好,使用方便。
Serial communication is the key to achieve micro-hardness computer measurement. This paper focuses on the use of MSComm VC ++ platform development of computer and microhardness tester serial communication real-time data display and data processing principles, as well as the use of SQL Server and VC ++ ADO database access technology to develop data management system processes and methods. Developed by the measurement software interface friendly and easy to use.
