摘要
电动汽车充电管理系统需要车辆管理部门、充电管理系统、电力配电系统等多个信息系统之间相互交换信息、协调工作,有序地完成充电管理。但是作为国家保密单位,需要保证各自内网信息的安全,在此基础上保证系统之间可靠的信息交互。为此在各系统的对外通信端增加了交互数据服务器、交互通信机,利用USB2.0OTG技术将内外网安全隔离,再由两个系统的交互通信机完成信息的交互。这样组成的网间隔离系统,即可保护内网信息安全,又可提供稳定的信息交互,对我国电动汽车充电管理系统中的信息安全和交互提出一种可实践的借鉴方案。
Electric vehicle charge Management system requires the vehicle management department,charging management system,and power distribution system exchange informations,coordinate each other,orderly complete the charge management.As the national secret unit,they need to ensure their own intranet informa-tion security,and then ensure reliable information interaction between systems.Therefore at the external com-munication terminal,set up the interactive data server,and interactive communication machine.Using USB2 . 0 OTG technology to isolate internal and external network.The two interactive communication machine com-municate to exchange informations.The isolation system,not only protect security of Intranet information, but also provide information interaction stability.The system can be a practical solution for information isola-tion and exchange in electric vehicle charge management system.
