摘要
为解决牵引逆变器测试系统中局域网通信问题,研究了一种双网卡通信技术。该方法利用双网卡代替路由器,实现了工控机与控制机箱、被测DCU机箱的网络通信。经过试验验证可知,在控制机箱和被测DCU机箱均安装服务器程序,且工控机安装客户端程序的工况下,需将双网卡IP地址设置在不同的网段内,才能正确实现数据通信。该方法已成功应用深圳地铁5号线牵引逆变器测试系统中。
Dual net-interface card technology for solving LAN communication problems in inverter testing system was introduced in this paper. Replacing router by dual net-interface card, this method successfully achieved network communication among industrial control computer, control enclosure and measured DCU. Experiments results showed that with control enclosure and measured DCU installed service program, industrial control computer installed client program and IP addresses of dual net card configured in different network segments, data communication could be realize correctly. The technology has been applied in traction inverter measure system for Shenzhen metro line 5 vehicles.
