Power Station Data Acquisition Intelligent Analysis Solution

I. Solution Overview

1.1 Project Background

The customer's original solution was to place all power station data computation and AI inference on the cloud side, which consumed enormous cloud resources and had high costs. By adopting a cloud-edge collaborative solution, the AI data computation and inference part for each station on the cloud side can be moved to run on the edge computer side. The gateway uploads the computation results to the cloud in real-time, and the cloud only handles data display and related scheduling work.

1.2 Construction Objectives

  • Full equipment networking, unified access management

  • Real-time data acquisition, standardization, cloud upload / platform integration

  • Support remote configuration, remote diagnosis, remote upgrade

  • Local AI inference and analysis of data

  • Achieve alarms, linkage, visualization, and report analysis

  • Improve operation and maintenance efficiency, reduce manual inspection costs

  • Secure, stable, easy to expand, easy to maintain
