A cross platform and multi node test monitoring software design method is proposed to meet the visualizationmonitoring requirements of radar tracks and platform position for multiple nodes in distributed system experiments, while alsoconsidering the requirements of domestic independent and controllable design. Qt is used for cross-platform design, andQtWebEngine is used to embed Web pages loaded with Google-Map to display two-dimensional Geographic Information System(GIS) map. The test data is collected by network packet capture and the radar tracks of different nodes are displayed on the map afterBowring’s coordinate transformation calculating. The test monitoring software implemented according to the method can meet theneeds of the task normally, has the advantages of low development cost and short development cycle, and has good application value.
