用Agent通信引擎实现电气绝缘监测数据远程传输

针对电气设备绝缘在线监测系统中数据采集单元比较完善,而监测数据传输处理部分存在数据存储和管理结构不太合理、远程传输控制缺乏扩展性和可靠性等情况,给出了一种监测系统数据传输处理模型.该模型采用数据库技术管理数据;利用将PcAnywhere作为后台通信引擎的Agent对象代理机制实现远程通信和远程控制,自动将从本地最近采集、存放在数据库中的数据压缩后同步传输到远端主控计算机,并通过远程过程调用将压缩的数据解压,存放到对应主控端数据库中.实际应用表明该方法稳定可靠,效果理想.

IMPLEMENTATION OF REMOTE TRANSMISSION OF ELECTRIC INSULATION MONITORING DATA USING THE COMMUNICATION ENGINE AGENT

Although the current data collecting units in the online electric devices insulation monitoring system are relatively consummate, there are some deficiency in the post-processing of collected data such as irrational data storage and management structure and lack of extensibility and reliability in remote communication and data transmission. In this paper, a practical data transmission model for the monitoring system is presented. The model uses database technology to manage data and an agent mechanism with PcAnywhere as the background communication engine to perform communication and remote control between the industrial control computer and the remote computer. Thus the monitoring system can send the data stored in and extracted from the local database to the remote computer after compression, which will automatically decompress and put the data into the global database. This model has proved reliable and effective in field application.
