摘　　要：从生产实际出发,在现有技术条件的基础上,根据设备供应商对设备维护的实际需求,设计了一套基于西门子 S7-200可编程控制器、互联网和虚拟专用网络技术的,应用于塑料挤出机的远程监控系统。利用该系统,当远端用户的设备出现故障而请求技术服务时,设备制造厂家可以迅速的通过互联网在设备诊断中心对远端故障设备进行快速诊断和维护,从而大大提高售后服务水平和质量,降低服务成本。本系统远程访问响应时间小于1 s,满足在线诊断的实际要求。A remote monitoring system was designed for plastic extruder based on the technology of PLC, Internet, and VPN. When the remote equipment request technique service, this system in the equipment diagnosis center realizes remote monitoring and data acquisition fast through the internet. Therefore, the system improves post sale service and cuts down service cost. In this system, the response time of remote access was less than 1 s, meeting equipment demands.
