and step 216, acquiring a pre-stored direct current engineering physical structure diagram.

Mapping association means that when a certain structure in the direct-current engineering physical structure diagram is operated, the corresponding link in a target link diagram can be jumped to. For example, in fig. 19, the direct current engineering physical structure diagram of the station 1 and the direct current engineering physical structure diagram of the station 2 may perform automatic mapping association according to the target link diagram, so as to implement a connected logical link.

And step 218, receiving the mapping association operation, responding to the mapping association operation, and performing mapping association on a second sub-physical structure diagram in the direct current engineering physical structure diagram to obtain a target direct current engineering visual diagram.

In this embodiment of the present invention, the mapping association operation may be sent by the user based on the second sub-physical structure diagram in the direct current engineering physical structure diagram, for example, a right click is made on a first link in the second physical structure diagram, and "link association" is selected, and a second link in the second physical structure diagram may be selected in the pop-up interface to obtain the mapping association operation, so that the mapping association may be performed on the second sub-physical structure diagram in the direct current engineering physical structure diagram by jumping from the first link to the second link. As shown in fig. 19, for the second sub-physical structure diagram corresponding to the station 1 and the

switches

1 and 2, the mapping association between the station 2 and the

switches

1 and 2 needs to be performed manually by a user.

And d3, determining whether the communication channel or the communication port is conducted or not based on the output result to perform fault location analysis.

In the embodiment of the invention, if the output result is OK, the physical circuit outputting the output result can be determined to be normal; if the output result is Error, it can be determined that the physical loop outputting the output result has a fault.

And step 220, if the fault exists, outputting fault prompt information at the fault position of the target direct current engineering visual image.
