摘要
在工业现场 ,监控系统经常采用 RS- 4 85 / 4 2 3/ 4 2 2通信标准。然而 ,在 Windows2 K平台下 ,复杂的多机通信和大数据量的传输会加重计算机的负担。作者采用自制的多机通信卡解决了这一问题。本文介绍了 Windows 2 K平台下多机通信的基本原理 ,论述了多机通信卡的设计方法 ,进一步阐述了驱动程序设计的一般原则。
In the industry, RS-485/423/422 communication specification is frequently applied. However, when multi-computer communications and transfers with mass data on Windows 2K platform, the computer system will be burdended. The paper presents the multi-computer card as a solution, it′s conception and design method are introduced, and the principle of the device driver is also given.
