基于C/S结构的三层网络运行模式开发了一种集成式数控设备网络控制系统。该系统可同时满足通过串口和以太网口通信的数控设备联网需求,具有多线程运行机制。系统功能模块主要包括通讯管理子系统、数控设备管理子系统、数据库子系统和网络监控子系统等。深入分析了系统的实时性和可靠性,并采用DES算法来提高数据的保密性。系统测试结果表明该网络数控系统可以和多个设备及客户端进行信息交换,并能通过网络对数控设备进行视频监视和远程控制。
Based on C / S structure of three-layer network operation mode, an integrated NC equipment network control system was developed. The system can simultaneously meet the needs of networked devices communicating through the serial port and the Ethernet port, with multi-thread running mechanism. System function modules include communication management subsystem, numerical control equipment management subsystem, database subsystem and network monitoring subsystem. In-depth analysis of the system’s real-time and reliability, and the use of DES algorithm to improve data confidentiality. System test results show that the networked numerical control system can exchange information with multiple devices and clients, and can carry out video surveillance and remote control of numerical control devices through the network.
