Abstract: Aiming at the four major problems of "bulkiness, high cost, lack of resources, and difficulty" existing in on-site work and training for professionals in electricity meter installation and connection and electricity inspection in the field of power marketing, this paper designs a miniaturized, integrated, and intelligent simulation training system. This system uses the method of camera and AI recognition to collect the operation information of trainees. It cooperates with PC control software to judge the wiring situation of trainees and provide feedback on operation errors for real-time correction, fundamentally improving the training quality of trainees. At the same time, this system also has the advantages of high simulation degree, easy operation, and good safety, with significant practical benefits. It is worthy of in-depth research and wide application.
