利用与一台机器连接的两个条码阅读器,我需要在MySQL数据库中储存条码价值、读物和日值。
读者为USB,但使用序列港口环境,因此通过COM港连接。 最初,我打算通过简单的网络形式收集数据,但需要两个相联的读者同时防止这种情况(因为有输入冲突的风险)。
首先,这似乎可行吗? 如果这样做可行,我最好用哪一种语言写这句话?
你可以有多个读者附属于你的PC,你只是指派了他们不同的港口号码(也许可以自动地这样做)。
您可以使用多种不同语言将条码读物者所读的信息输入你的数据库,而且确实取决于哪一种人最了解,尽管我建议使用网站偏颇的语言,例如C#、C++、 Java、VB.NET、VB、Delphi等。 此外,最好选择一个在你的目标平台上开展工作的方案。
认为条码数据往往带有特征,因此实际上很难处理。
You can use languages like Java or Vb or even C#. There are examples available for serial port programming in Java as well. One example you can find is Here. Hope this helps.
