基于数控机床远程监控技术的安全传输系统开发

摘要

为了保证数控机床远程监控系统数据传输的安全性,文章在Linux及windows系统下,基于C/S层次结构,采用TCP/IP网络协议,利用C/C++语言、VS2008开发软件、oracle数据库,开发了基于非圆磨削数控机床远程监控系统的安全传输系统,该系统实现了各监控机床站点的身份认证,密钥协商、密钥校验、密钥周期更换,以及业务数据录入数据库和对传输数据的加解密等功能,具有不依附于平台、加密实时性高、易用性好和维护性强等优点.最后将系统部署到西门子840Dsl实验台和远程监控PC端进行实验验证,实验结果表明软件运行稳定,达到了预期的目的.%In order to guarantee the data transmission security of the remote monitoring system of CNC machine tools.A system is developed based on non-circular grinding CNC machine remote monitoring system,using TCP/IP network protocol and C/S hierarchy by C/C++ language VS2008 software、Oracle database under the Linus and Windows systems.It can realize the functions of the identity authentication of the monitoring sites of the machine, key agreement, key checking, the key cycle changing ,putting business data into database and encryption of transmission data.and it has the advantages of not depending on the platform,hight Real-time of encryption,good usability and strong maintainability,etc.In the end ,we conduct the experiment verification by arranging the system into Siemens 840Dsl test bench and the remote monitoring PC platform.The experimental results show that the software runs stably and expected results have been achieved.
