Problems solved by technology
Another example: a chemical leak occurs at a facility, and their community alarm communication system fails, so local residents cannot receive evacuation warnings; if the leak detection system fails to alert operators, hazardous substances may leak into water supply pipes
Another example: if the operators of the power system do not receive the warning that the power line is interrupted, they cannot take timely measures to prevent power outages; and in terms of transportation, if the subway control room cannot receive the data updated by the railway tracking monitoring sensor, the subway train may crash
However, the issue of information security is not considered in the existing industrial control systems, resulting in security problems in the security gateways in many industrial control systems
Especially for the gas industry, the existing industrial security gateways cannot meet the security protection needs of the gas industry, and cannot perform DPI on the gas industry-specific protocols, and cannot achieve the security protection of gas industry equipment

The invention discloses an intelligent gateway for the gas industry and a data transmission method. The intelligent gateway comprises a data link controller, a first data link and a second data link,wherein the first data link and the second data link are connected in parallel, the working states of the first data link and the second data link are detected based on the data link controller, and the first data link and the second data link are not communicated with each other. The intelligent gateway comprises the first data link and the second data link, and the first data link and the seconddata link do not communicate with each other, so that the effect of protecting multiple groups of data links is achieved. Meanwhile, when one data link of the intelligent gateway breaks down, data transmission can still be achieved through the other data link, the safety of the intelligent gateway is improved, and therefore the safety of the whole network environment is guaranteed.
Description
technical field [0001] The invention relates to the technical field of network security, in particular to an intelligent gateway used in the gas industry. Background technique [0002] Industrial control systems are widely used in various industries. From a broad perspective, any occasion where industrial control equipment can be applied can be called an industrial control system. Both manufacturing and processing are inseparable from industrial control systems. Especially in critical infrastructure, such as chemical industry, water conservancy facilities, financial services, commercial facilities, defense industry, food industry, communications, emergency response, government facilities, key manufacturing, energy, public health, water treatment , information technology, nuclear reaction facilities, transportation systems and other important sectors that support modern society. [0003] At present, the industrial control systems used in these important facilities are facin...
