矢量化的电网厂站接线图需要调度运维人员参考设计图纸进行人工绘制及导入,工作量巨大且极易出错。针对电网厂站接线图中图元、文字以及接线关系3个核心的识别问题,提出一套基于人工智能的完整电网厂站接线图识别方法,显著提升识别的效率和准确性。通过结合分级预处理的重叠滑窗机制与YOLOv4算法,解决电网厂站接线图的“大图像小图元检测”问题;通过迁移学习与卷积循环神经网络结合,提升包含中文电气文本的识别率;通过嵌入电气领域知识与规则,提升接线识别的准确率。最后,根据获取的电气元件信息、文本信息、连接线信息,完成其他下游任务。采用实际调度系统导出的电网接线图数据集,设计了图元、文字、接线识别三方面的对比实验,验证了所提方法的有效性。
Vectorized wiring diagrams for power plants and substations need to be manually drawn and imported by dispatching operation and maintenance personnel with reference to design drawings
which is labor-intensive and error-prone. Aiming at the three core recognition problems
i.e.
graphic element
text and wiring relationship of the wiring diagram for power plants and substations
a complete method of wiring diagram recognition for power plants and substations based on artificial intelligence is proposed to significantly improve the efficiency and accuracy of recognition. Through the combination of overlapping sliding window mechanism of hierarchical preprocessing and YOLOv4 algorithm
the problem of “large image and small graphic element detection” of the wiring diagram recognition for power plants and substations is solved. Through the combination of transfer learning and convolutional recurrent neural network
the recognition rate of Chinese electrical texts is improved. Embedded with the electrical domain knowledge and rules
the accuracy of wiring recognition is improved. Finally
according to the obtained electrical component information
text information
connection line information
other downstream tasks are completed. Using the data set of grid wiring diagram derived from the actual dispatching system
the comparison experiments of graphic element
text and wiring recognition are designed to verify the effectiveness of the proposed method.
