The invention discloses an elevator accident prediction method and device, a medium and a product, and relates to the field of elevator accident prediction.The method comprises the steps that working parameters of a to-be-detected elevator are obtained; the working parameters comprise an operation parameter, a management parameter and a riding parameter; inputting the working parameters into an elevator accident prediction model to obtain a fault occurrence probability corresponding to the to-be-detected elevator; the elevator accident prediction model is a deep learning network; when the fault occurrence probability exceeds a preset threshold value, the elevator accident type is determined according to the fault occurrence probability; the elevator accident type serves as a target variable, and each working parameter serves as a characteristic variable; respectively calculating standardized mutual information values of the target variable and each characteristic variable, and determining a maximum standardized mutual information value; and determining a to-be-optimized fault combination according to the maximum standardized mutual information value. According to the invention, the elevator accident can be accurately predicted.
