The invention provides a blast furnace hearth state determination method and device and electronic equipment. The blast furnace hearth state determination method comprises the steps: under a standardstate, obtaining state values of multiple state parameters of a target blast furnace in a preset time period (in a standard state, acquiring state values of multiple state parameters, related to the blast furnace hearth state, of the target blast furnace in a preset time period), wherein the multiple state parameters comprise a parameter for representing the hearth bottom heat level of the targetblast furnace, a parameter for representing the hearth heat level in the smelting period, a parameter for representing the blast furnace tuyere front end heat level and a parameter for representing the synchronism of discharging molten iron and generating molten iron by blast furnace smelting; calculating standard state values corresponding to the multiple state parameters according to the parameter values of the plurality of state parameters; collecting real-time state values of the multiple state parameters of the target blast furnace at a target time; and calculating a hearth activity indexof the target blast furnace according to the real-time state values and the standard state values of the multiple state parameters.
