基于串口通信的肉牛企业标签打印系统的研究和设计

Label Printing System of the beef cattle business based on serial port communication

介绍了现代肉牛企业信息管理系统中实用的串口通信技术和条码标签打印技术。在Visual C++6.0环境中用Microsoft Communication Control控件实现计算机与电子秤的串口通信,使计算机得到牛胴体或牛胴体分割肉的重量信息。然后利用Code128B条码规则实现重量、质量等级等信息的编码,并通过标签打印机把编码得到的条码打印出来。

The practical serial port communication and barcode in Information Management System for beef cattle business was introduced.The serial port communication between computer and electronic weighter was realized by Microsoft Communication Control,which was supplied by Visual C ＋ ＋6.0.Then,the weight data of beef carcass or beef carcass cut was received by the computer.Applying the rule of Code128B,the data of weight and quality grade was coded to barcode.Finally,the barcode could be printed by label printer.
