摘要
组合称重是实现高速、高精度定量包装的一个研究方向,本文阐述了组合秤的机械结构、工作流程、控制系统的组成等,同时,详细介绍了上位机在VC++6.0开发环境中通过API函数实现与多个下位机进行异步串行通讯的主要步骤。
Combination weig hting is a research direction of realizing ration packing with hig h velocity and hig h resolution.This paper introduces mechanical structure,working cycle,controlling system of combination bal-ance and so on.At the same time,it describes main steps of asynchronous serial communication between PC and some microcomputers by API functions in VC++development environment in detail.
