集散式物料发放计量系统的数据采集与网络通讯

Data Acquisition and Net Communication of Distributed Con trol Delivery System at NT Environment

论述了在WindowsNT环境、多串行口通讯状态下 ,集散式物料发放计量系统的数据采集与网络通讯的原理和实现方法。叙述了系统的软硬件实现方案。该系统基于WindowsNT平台上 ,用MOSA卡扩展串行口。使用VFP6开发工具 ,利用MSCOMM32 .OCX与Winsock控件实现上下位机的串行端口通讯以及上位机与服务器的通讯 ,实现数据采集与管理同步 。

This Paper discussed the data acquisition and n et communication′s principles and methods of delivery Management System based on WindowsNT with multi- serial interface. In order to realize the data acquisit ion and management at the same time, the methods of developing multi-serial com munication in Visual Foxpro 6 0 environment, especially using communication con trolware MSCOMM32.OCX, WinSock and MOSA Card, solving transmission and receptio n of data, are introduced.This will be help to increase the level of automatio n of oil delivery system.
