Modern site management has made significant progress, and many advancing equipment and technologies have been introduced into the site management process. During power transmission and transformation construction, safety accidents often occur due to fatigue construction or negative emotions. Embedded Devices plus AI is an advanced solution that monitors and identifies worker sentiment in real-time. The LERM model optimized in this paper can run well on embedded devices with reliable accuracy. This model can be well applied to surveillance camera equipment, at low cost, fast response, and high recognition accuracy. The application of cameras with embedded LERM models on power transmission and transformation sites can identify staff emotions in real-time and alarm managers. As a result of this application, fatigue construction or negative emotions can be avoided as a safety hazard in power transmission and transformation construction personnel.
