The invention discloses a DC conversion pole primitive picture comprehensive display method. The method includes a first step: analyzing a graph G file, and reading basic information for drawing a DC conversion pole primitive; a second step: automatically drawing the DC conversion pole primitive according to the basic information of the G file, and automatically generating a display interface of the DC conversion pole primitive; a third step: uploading dynamic attributes of the DC conversion pole primitive at regular time, allowing the DC conversion pole primitive to perform data communication through a background data interface and a service layer jar package, and performing data updating at regular time; and a fourth step: acquiring coloring information of the DC conversion pole primitive at regular time, and coloring a direct current pole and an alternating current pole according to voltage values corresponding to the direct current pole and the alternating current pole of the DC conversion pole primitive and voltage level colors corresponding to the voltage values. The method can effectively achieve comprehensive information displaying of the DC conversion pole primitive, and has universality and validity.
