基于信息冗余的条形码容错技术研究

Research on Data-Reliability of Bar Code Based on Information Redundancy

研究了条形码在恶劣生产环境中如何保证其数据信息可靠性的方法。基于信息冗余技术,提出了一种保证条形码数据可靠性的方法。该方法通过改变编码方式,结合Visual Basic6.0编程实现条形码译码的自纠错功能,对保证所采集数据信息的可靠性有一定积极作用。

This paper presents how to guarantee the data-reliability of bar code when barcode system is used under atrocious environment. Based on the information redundancy technology, an alternative method to guarantee the integrity of bar code data is given. By changing the way of coding and using Visual Basic 6.0 programming, self-correction function is developed. This method has positive effect on the integrity and accuracy of data collected to some extent.
