There are many measurement points in graphic elements and configuration library in the distribution automation graphic system, which are not only complex to configure, but also difficult to process the graphic data. To solve the problem, a method of primitive real time encoding and storage is put forward. Based on the monitoring platform of OpenSCADA, through the analysis of the primitive structure, a transformer element coordinate system is designed. Base64 encoding is used to storage the primitive, and Java is employed to implement the dynamic processing of the primitive. Taking the monitoring interface of 10 kV distribution network of Beijing East Railway Station as an example, this paper proceeds with a test on the encoding storage and display. The results show that designing graphical interface of monitoring system by primitive encoding of the graph-database integration can simplify the processing of the monitor graphics system, and decrease the difficulty of system maintenance, and accomplish the graphic element design and storage at a time, which has the important value for practical project.
