3pm on March 19, 2021，from the Graduate School of Shandong University、Hosted by the Graduate Work Department of the Party Committee，The 14th Issue 14 (Total 1003), hosted by the School of Electrical Engineering, was held at the Fifth Floor Conference Room of the Electric Power Building of Qianfoshan Campus。This forum invited the chief engineer of Xintong Electronic Co., Ltd., Shandong Province、Master's instructor of the School of Electrical and Electronic Engineering, Shandong University of Technology、China Electric Power Enterprise Federation National Union National Inspection and Power Supply and distribution technology collaborative network、Member of the Standardization Management Committee of the Shandong Electronics Society -Dr. Cai Fudong，The theme of the lecture is "AI Technology in the Smart Operations of the Power Network"。This forum is chaired by Professor Wang Xiaolong。

Report starting，General Manager Li Li of Shandong Xintong Electronic Co., Ltd. first gave a statement from the enterprise。First briefly introduced Xintong Company，Including the qualification honor obtained by the company、Company development process、Including the chairman of Li Quan、General Manager Li Li、Core team, including Cai Fudong's chief engineer, etc.。otherwise，General Manager Li Li also for the company's research and development power、Core technology、Target Market、Introduction of corporate culture and some products，Let students have a general understanding of Xintong Company。

Next，Dr. Cai Fudong, chief engineer of Shandong Xintong Electronic Co., Ltd.。The report is divided into an overhead transmission line operation and maintenance、Deep learning and target detection、Image detection technology application、Sound detection technology application four parts。Dr. Cai Fudong first talked about the overhead transmission line，There are many existence points for overhead transmission lines in China、Line length、Face wide、Complex environment、Difficulty of power supply and communication，There is a lightning strike、External force damage、Bird Knight、Ice Knight、Wind damage and other channel hidden dangers，Therefore, the maintenance of the line has become the main problem facing。Later, Dr. Cai introduced some inspection methods and smart inspection mode for transmission lines，The evolution of traditional image algorithm to deep learning target detection technology，Essence of feature extraction through the traversal image，then compare the feature，Results pass the accuracy rate、accuracy rate、Recall rate、speed、Evaluation indicators such as complexity to measure。Analysis of deep learning in face recognition、Vehicle detection、Pedestrian count、Autonomous driving、Application in the fields of security systems，In terms of transmission and operation and maintenance hidden target detection，Accumulate through big data、Model training、Test、deployment application and other processes，Realized key technologies for target detection，to achieve control omissions，The purpose of reducing the false alarm。Combined with laser point cloud integration application realizes hidden environmental hazards、tree bamboo growth、Circuit Arc、Cover ice、Dance and other hidden dangers to detect the function。Finally, Dr. Cai explained the application of sound detection technology，Sound detection and intelligent recognition、Similar recognition、Sound source positioning and other technologies to realize the detection of hidden dangers of the line。

In the question session，Students on the precision of the standard detection algorithm model、Method of the Separation of Sound recognition Signal asked Dr. Cai，Dr. Cai answered the questions of the students one by one。Professor Wang Xiaolong also consults the technical bottlenecks encountered by the current Institute.，Dr. Cai also put forward his own opinions and ideas。otherwise，Dr. Cai also shared his growth experience since college，And I hope that students can cherish the big time of the mountain，Struggle Figure Strong，Become a better person。This issue"His Majesty" Graduate Academic Forum has ended successfully in the warm applause of teachers and students。
