Embodiment Construction

[0022] In order to make the above and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments are listed below and shown in the accompanying drawings in detail as follows.

[0023] like figure 1 as shown, figure 1 It is a structural diagram of the DMZ-based oil and gas industry Internet data processing system of the present invention. The DMZ-based oil and gas industry Internet data processing system includes multiple remote data transmission units (referred to as DTU data transmission units 1-n) installed on site, and a data processing subsystem (referred to as DMZ subsystem 20) deployed in a security isolation zone. ) and a data processing subsystem deployed on the industrial control network (referred to as the industrial control subsystem 30).

[0024] The DTU collection and transmission units 1-n are responsible for collecting data signals from remote well stations in oil and gas fields, and realize data interaction ...

Abstract

The invention provides a DMZ-based oil and gas industry internet data processing system, which comprises a plurality of DTU acquisition and transmission units, a DMZ subsystem and an industrial control subsystem; the plurality of DTU acquisition and transmission units are used for collecting field data signals of long-distance well stations of oil and gas fields and carrying out data interaction with the DMZ subsystem through a communication operation network; the DMZ subsystem is deployed in an isolation service area of a communication operator, on one hand, the DMZ subsystem communicates with the DTU acquisition and transmission units, on the other hand, the DMZ subsystem respondsto a data acquisition request and a remote control request of an internal network of an oil and gas field enterprise; the industrial control subsystem is deployed in a certain industrial control network of the oil and gas field and communicates with an office network and the DMZ subsystem through a gatekeeper or a firewall so as to collect, monitor and control data of all well stations. According to the system, the network security and the data transmission rate of data processing are fully considered, and the information privacy, the high speed and the industrial control security of remote data acquisition of the oil and gas field are guaranteed.

Description

technical field [0001] The invention relates to the technical field of oil and gas field development, in particular to a DMZ-based oil and gas industry Internet data processing system. Background technique [0002] Oil and gas field enterprises are gradually realizing the importance of communication security when carrying out informatization construction. Most enterprises have strengthened the isolation between the corporate office network and the industrial control network, and the enterprise network and the Internet by deploying measures such as gatekeepers and firewalls, and strictly controlled the export of industrial control network servers. However, there are problems such as inadequate supervision of key industrial control servers, random plugging and unplugging of external devices, and weak remote access authentication, which reduces the security of the system to a certain extent. Establishing a demilitarized zone (Demilitarized Zone) between the oil and gas field e...
