According to analyzing network data, compared with accessing data type with pre-configured mandate, class accessed if being not belonging to authorize
Debugging network data in type list, isolation control module then abandon the debugging network data, simultaneously close off maintenance and calculate passenger
Family end links and terminates debugging, while provides alarm by soft barrier assembly man-machine interface.
Certainly, can also be according to debugging need after isolation control module receives the debugging network data for safeguarding computer client
Will, debugging network data is not analyzed, and debugging network data are directly submitted into link establishment and data forwarding module.
Step 6：Link establishment and data forwarding module will isolate the debugging network data of control module submission, pass through step
The link established in 3 is transmitted to debugger object.
In the present embodiment, the link establishment of soft barrier assembly and data forwarding module will isolate the tune of control module submission
Network data is tried, debugger object telemechanical apparatus is transmitted to by the link established in step 3.
Step 7：The debugging result that debugger object is replied is replied to isolation control mould by link establishment and data forwarding module
Block.
In the present embodiment, debugger object telemechanical apparatus replys debugging result, soft isolation after receiving debugging network data
The debugging result that debugger object telemechanical apparatus is replied is replied to isolation control mould by the link establishment of component and data forwarding module
Block.
Step 8：Debugging result is replied to client by isolation control module again.
In the present embodiment, the debugging result of telemechanical apparatus is replied to maintenance by the isolation control module of soft barrier assembly again
Computer client.Step 8 is arrived by repeat step 5 afterwards, soft isolation is carried out in soft barrier assembly, access monitoring and accesses control
In the case of system, complete working service computer and access debugging substation telemechanical apparatus.
