The invention relates to an elevator position estimation method and device, equipment, a storage medium and a program product. The method comprises the steps that electric signal collection is conducted on the elevator traction machine, and voltage and current in a target time period are obtained; the voltage frequency of the elevator traction machine is calculated based on the voltage, the target time period and the electric signal zero-crossing number; the current frequency of the elevator traction machine is determined; the angular speed of the elevator traction machine is calculated, the angular speed obtained based on the voltage frequency or the current frequency is input into an elevator system mathematical model for displacement calculation, and displacement information of an elevator car is obtained; and the position information of the elevator car is determined based on the displacement information and accumulated displacement information of the elevator car in the ascending or descending stage. By adopting the method, the estimation accuracy of the elevator position can be effectively improved.
