With the continuous development of information technology,intelligent manufacturing is considered one of the important directions for the future of the manufacturing industry.As the core of intelligent manufacturing,intelligent factories have significant research value and significance.However,intelligent factories continue to encounter significant challenges during development,including equipment communication speeds and insufficient production intelligence,with communication speeds being the primary bottleneck.In order to address the existing shortcomings of intelligent factories,this article proposes an implementation solution for an intelligent factory control system that combines 5G communication technology with Internet of Things(IoT)technology,illustrated by the development of a smart factory control system for the Hulunbuir Aluminum Electric Smart Factory.This solution aims to enhance device communication quality and efficiency,thereby advancing research in intelligent factory technologies.Through the analysis of the system's functional test results and the performance test results of the 5G private network,it is demonstrated that the system has good application effects in practical scenarios.
