On-line monitoring and acquiring system for oil chromatography and on-line monitoring method thereof

Abstract

An on-line monitoring and acquiring system for an oil chromatography belongs to the technical field of transformer detection and comprises an acquisition server, as well as a GPRS (General Packet Radio Service) communication module and an on-line monitoring platform which are connected with the acquisition server, wherein one network interface of the acquisition server adopting a dual-network-port structure is connected with the GPRS communication module and used for acquiring monitoring information, and the other network interface is accessed into an electric power private network and used for transmitting the monitoring information to the on-line monitoring platform; the GPRS communication module connected to an APN (Access Point Name) private network converts a wire communication message into an APN private network communication message; the acquisition server and an oil chromatography on-line monitoring device are connected through the APN private network based on GPRS communication and used for transmitting the monitoring information; and the acquisition server real-timely transmits the monitoring information to the on-line monitoring platform through the electric power private network. According to the invention, the APN private network is taken as a transport network for both remote control and data acquisition to remotely control the on-line monitoring state for the oil chromatography and collect analytical data so as to monitor the running state of a transformer.

Description

technical field [0001] The invention relates to an acquisition system and method in the technical field of transformer detection, in particular to an oil chromatography online monitoring system and method for communication control, data acquisition and transformer fault analysis based on APN private network of GPRS communication. Background technique [0002] With the large-scale application of oil chromatography online monitoring in substations, it has become a realistic demand for how to perform remote control and data acquisition of oil chromatography online monitoring devices in substations located in remote and inconvenient locations. Existing wireless communication technologies generally use GSM SMS, public network communication based on GPRS Internet, regional communication based on radio stations, and radio frequency. The problem is that the Internet-based public network communication has great security problems and is easily attacked or intercepted; radio-based comm...

Problems solved by technology

However, this prior art only describes a method for fault analysis based on real-time data rather than an oil chromatography online monitoring and acquisition system and method, so there is no patent conflict. This prior art can only be based on whether the data collected by the acquisition module exceeds the warning value. Decide whether to generate a report, and the failure analysis only provides a three-ratio analysis
