Abstract: As the foundation of digital economy development, the promotion of infrastructure business is of great significance to high-quality development of economy. Compared with the traditional infrastructure, the new infrastructure is more technical, more professional, and more intelligent. Taking the abnormal object detection in transmission lines as example, it becomes more important to use front-end intelligent device in new infrastructure. Compared with the common used cloud platform, the edge computing device is closer to the data source, so it is more responsive and more reliable, because of this, edge computing device is more suitable for application in unstable network environment or higher response scenarios.
