Danger Points Detection

Summary

Judge if the point is a danger point according to the clearance distance and the set safety distance. The interface of the clearance danger point detect function is shown as follow. This function can process multiple data simultaneously. Click to add the data to be processed. Click to remove the selected data(remove the first record of the list if no data is selected). Click to clear the data list.

Usage

Click Realtime Analysis > Danger Points

Settings

• Detection Parameter:
  • Cluster By Class( Unchecked by default.): Used to control whether to cluster the result by class.If this option is checked, the danger points will be clustered into different groups if they are in different classes; otherwise, the class information will not influence the clustering process. The software can record the user's current settings and automatically restore the settings when opened again.
  • Min Distance (meters) (default value is "0.3"): Points with clearance distance less than this distance are not detected as danger points, as they are considered to be noise. The software can record the user's current settings and automatically restore the settings when opened again.
  • Safe Distance (meter) (default value is "4.5"): If the distance between the detected point and the power line point is greater than the minimum distance and less than or equal to the safe distance, the point is considered to be a danger point. If the xml file is not set, user needs to enter the safety distance; otherwise, this parameter is extracted from the xml file. When using the xml to set the parameter, user can set different safety distances for different classes, and for different severity level.
  • Cluster Threshold (meter) (default value is "15.0"): The maximum spatial separation distance when the detection results are clustered. This value should be smaller than the maximum clustering range. Three-dimensional Euclidean clustering is used to cluster the danger points. The software can record the user's current settings and automatically restore the settings when opened again.
  • Max Cluster Range (meters) (default value is "20.0"): After the detection results are clustered, if the length along the power line direction is greater than this value, they are divided into multiple dangerous point clusters. The software can record the user's current settings and automatically restore the settings when opened again.
• Vector File: Input the vector file in shp format. The software can record the user's current settings and user can restore the settings in the drop-down menu or select button next time when opening this function.
• Simulation File: Input the simulation file (*.LiSim file). The software can record the user's current settings and user can restore the settings in the drop-down menu or select button next time when opening this function.
• Threads Number (default value is "4"): Set the number of thread (1 to 32) to run this function. The software can record the currently setting and when the user open this function again, the setting will be kept.
• Default Value: Restore the default parameter settings.

Note: After the analysis, user can check the result accuracy in Clearance Danger Point List.

Note: If user opens the function from the vector real-time working conditions module, user needs to set the vector file; if user opens the function from the simulation working conditions module, user needs to set the working conditions simulation file.
