[0002] With the continuous growth of energy demand and the increasing awareness of environmental protection, energy conservation and emission reduction have become a global focus. Traditional energy management systems suffer from problems such as inaccurate monitoring, slow response speed, and limited energy-saving effects.

[0003] Most of my country's oilfields are low-energy, low-yield fields. The majority of oil production relies on water injection to force it into wells and pumping units (nodding donkeys) to lift it from the formation. In my country, trading water for oil and electricity for oil is currently the reality in oilfields, and electricity costs account for a significant proportion of oil extraction costs. Therefore, the oil industry places great importance on energy conservation, as saving electricity directly reduces oil extraction costs.
