Embodiment Construction
[0026] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals denote the same or similar parts in the drawings, and thus their repeated descriptions will be omitted.
[0027] The firewall system can be a router, or it can be a personal host, a main system, or a group of main systems, which specifically isolate the network or subnet from those protocols and services that may be abused by the main system outside the subnet. The firewall system is usually located at a higher-level gateway such as the connection between a network point and the Internet. At the same time, the firewall system can be lo...

The invention discloses a data transmission method and device for a firewall used for the operation and maintenance of a power secondary system. The method includes: establishing a temporary connection between a firewall device and a user device to be connected; the device identification and password of the user device obtained by the firewall device through the temporary connection; Authentication; after passing the authentication, the firewall maintains a connection with the user equipment for data transmission by the user equipment. The data transmission method and device for the firewall used for the operation and maintenance of the electric power secondary system involved in the present disclosure can realize data round-trip access to the protected network through low cost and simple deployment.
Description
technical field [0001] The present disclosure relates to the field of distribution network information processing, in particular to a method and device for data transmission of a firewall. Background technique [0002] The power system consists of power generation, power transmission, power transformation, power distribution, power consumption equipment and corresponding auxiliary systems. The electrical equipment of the power system has the definition of primary equipment and secondary equipment. Primary equipment (also known as main equipment) is the main body of the power system. It is the equipment that directly produces, transmits and distributes electric energy, including: generators, transformers, switching devices, power lines, transformers, lightning arresters, etc., with high voltage , High current characteristics. The circuit formed by the interconnection of primary equipment according to its purpose and function is called a primary circuit or primary wiring or ...
