The mine hoist has problems such as high power consumption,lack of safety assurance,and limited speed regulation range.Therefore,based on the analysis of the latest frequency conversion speed regulation technology of mine hoists,the research status of Shanxi underground coal mines is analyzed,and the direction of Shanxi coal mine transformation is proposed.A comprehensive upgrade plan for the mine hoist was proposed based on actual needs,and its power system and software and hardware systems were designed separately.Finally,parameter application testing and experiments will be conducted to analyze the overall stability improvement methods of the hoist during acceleration,deceleration,and constant speed operation,in order to improve the working safety factor and efficiency of the hoist.
