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 used for a firewall of power secondary system operation and maintenance. The method includes: establishing a temporary connection betweenfirewall equipment and user equipment to establish the connection; obtaining an equipment identifier and a password of the user equipment by the firewall equipment through the temporary connection; carrying out authentication by the firewall equipment according to the equipment identifier and the password; and after authentication succeeds, maintaining the connection with the user equipment by thefirewall to enable the user equipment to carry out data transmission. The data transmission method and device used for the firewall of power secondary system operation and maintenance related to by the disclosure can realize data round-trip access to a protected network through low costs and a manner of 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 ...
