[0002] The electrical equipment in hot rolling mills is diverse. Some older, lower-configuration, and equipment operating in special environments or with scattered installation locations lack real-time data signal acquisition capabilities. Sensors typically need to be placed at specific locations on the equipment. However, sometimes the equipment is precisely designed, and situations arise where the environment prevents updates or the addition of corresponding sensors. Therefore, collecting information on the operating status of equipment in hot rolling mills is challenging. Furthermore, some production lines are long and the environment is complex, making communication line connections susceptible to interference. Incomplete data collection on equipment operating status means that early equipment failures cannot be detected in time, leading to minor problems escalating into major malfunctions and severely impacting the stability of enterprise production.

[0003] Existing technologies and related literature cannot fully meet the complex realities of all application sites. More comprehensive methods and measures are needed to solve the problem of acquiring operating status signals of electrical equipment in all aspects. Summary of the Invention
