以太网物理隔离条件下实现自动数据同步

Design of serial port synchronization based on ethernet layer

企业在信息化建设过程中,经常遇到工作在企业内网的信息系统要与企业外网(互联网)的信息化系统进行数据交换,而企业内网与外网通常物理隔离,无法进行数据通信。在此情况下,可以采用计算机串口通信技术,在内外网分别部署一台具备串口通信的计算机,再使用串口直连的方式,让两台计算机实现串口通信,分析了内外数据的自动同步与交换,从而避免购买昂贵网闸设备,提出了以太网物理隔离条件下实现自动数据同步,经过编程设计运行结果表明,运行指标达到预期要求。

In the process of information construction,enterprises often encounter that the information system working in the enterprise intranet has to exchange data with the information system of the enterprise extranet(Internet),and the enterprise extranet is usually physically isolated from the extranet,no data communication. In this case,we can use computer serial communication technology,deploy a computer with serial communication in the internal and external network,and then use serial direct connection to let two computers realize serial communication,this paper analyzes the automatic synchronization and exchange of internal and external data,so as to avoid purchasing expensive network gate equipment,and puts forward the realization of automatic data synchronization under the condition of ethernet physical isolation,the operation index has reached the expected requirement.
