A portable operation and maintenance bastion computer system

Abstract

The invention relates to a portable operation and maintenance bastion computer system, comprising a soft isolation module, a process management module, a message communication module and a man-machine interface module; the soft isolation module, the man-machine interface module and the process management module are respectively connected with the message communication module connect. The structure of the operation and maintenance bastion machine of this system is relatively simple, and the user is relatively simple to use; it can realize the monitoring and guarding of each process, and can realize the communication and interaction of each process inside the operation and maintenance bastion machine, and can provide a dedicated man-machine interface for power maintenance; network Access and debug the access behavior of the operating equipment in the substation, monitor and control, block and give an alarm when the operation and maintenance personnel access other network equipment without authorization; it can prevent the unauthorized network link initiated by the maintenance computer, and avoid the maintenance computer from affecting the operation and maintenance equipment cyber attack.

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
