Portable operation and maintenance bastion host system

Abstract

The invention relates to a portable operation and maintenance bastion host system comprising a soft isolation module, a process management module, a message communication module and a human-computer interface module, wherein the soft isolation module, the human-computer interface module and the process management module are separately connected with the message communication module. The portable operation and maintenance bastion host system is relatively concise in framework, and relatively simple for user; the monitoring and guard on each process can be achieved, the communication interactionof each process in the operation and maintenance bastion host can be achieved, and a dedicated human-computer interface can be provided for electric power maintenance; the access behavior of accessing and debugging transformer substation running equipment via a network is monitored and controlled, when the operation and maintenance personnel accesses the other network equipment in an unauthorizedmanner, the operation and maintenance personnel can be blocked and warning can be provided; an unauthorized network link initiated by a computer can be blocked and maintained, and the maintenance computer can be prevented from initiating a network attack to the operation and maintenance equipment.

Description

technical field [0001] The invention relates to the technical field of substation and main station operation and maintenance debugging, in particular to a portable operation and maintenance bastion machine system. Background technique [0002] At present, when the operation and maintenance personnel maintain and debug the network equipment such as measurement and control, protection and telecontrol of the operation of the substation, they usually directly connect the maintenance computer to the network switch of the substation to access and debug the target network equipment. The network structure of network access and debugging is as follows: figure 1 As shown, there is no isolation, access monitoring, and access control between the maintenance computer and the network equipment running in the substation. There is a risk of operation and maintenance personnel accessing other running network equipment without authorization, and there is also a risk that the maintenance comput...

Problems solved by technology

[0002] At present, when the operation and maintenance personnel maintain and debug the network equipment such as measurement and control, protection and telecontrol of the operation of the substation, they usually directly connect the maintenance computer to the network switch of the substation to access and debug the target network equipment. The network structure of network access and debugging is as follows: figure 1 As shown, there is no isolation, access monitoring, and access control between the maintenance computer and the network equipment running in the substation. There is a risk of operation and maintenance personnel accessing other running network equipment without authorization, and there is also a risk that the maintenance computer carries a virus or the network attacks the running equipment.

[0003] Moreover, the design of the operation and maintenance bastion machine used in traditional enterprises is too complex and huge, not targeted, and not customized and streamlined according to user needs
