The embodiment of the invention discloses a data processing method. The method comprises the following steps: acquiring a pre-stored direct-current engineering tree structure diagram; obtaining at least one visualization program based on the DC engineering tree structure diagram, wherein the at least one visualization program corresponds to at least one target device in the DC engineering tree structure diagram; acquiring data transceiving information between nodes in the direct-current engineering tree structure diagram from the at least one visualization program; creating a target link diagram based on the data transceiving information and the direct-current engineering tree structure diagram; and sequentially displaying a plurality of views in the target link diagram based on the hierarchy of the DC engineering tree structure diagram. The embodiment of the invention further provides equipment and a computer readable storage medium.
