摘要
提出了一种船海工程机电设备远程虚拟局域网的构建方法,对已交付且控制器IP地址相同的设备进行虚拟地址映射,在不修改控制器IP地址的前提下,将这些物理地址相同的设备构成一个安全加密虚拟局域网,实现设备的安全互联互通。设备作为现场端,通过安装有OpenVPN客户端证书的4G路由器连接到企业内部的OpenVPN服务器,与OpenVPN服务器处于同一局域网下的调试PC,通过搭建好的基于OpenVPN的远程安全加密虚拟局域网,实现对船端现场设备的远程调试、远程下载,实现虚拟局域网内所有终端(现场设备、调试PC等)的安全互联互通。
The study proposes a construction method for remote virtual local network of marine engineering electromechanical equipment.Many delivered electromechanical equipments with the same IP address will be mapped using different virtual IP address,and constitutes a safety and encrypted virtual local area network,which can realize the interconnection.The equipment on ship field is connected to the OpenVPN server located within the enterprise by means of the 4G router installed OpenVPN client certificate.The debugging PC situated on the same local area network with the OpenVPN server can remotely program debug and code download for the equipment with the same IP address on ship field,which brings out the interconnection of all the terminals such as the equipment on ship,the debugging PC within the enterprise.
