The invention discloses a storage tank fuel remaining amount estimation method based on data driving, which comprises the following steps of: firstly, collecting data, constructing a data set, preprocessing the data of the data set, dividing into a training set and a test set, then extracting basic characteristics of the preprocessed data, and extracting high-order time series data based on the basic characteristics; constructing a fuel remaining amount estimation model, and training the model; and finally, estimating the fuel remaining amount in real time based on the trained fuel remaining amount estimation model. According to the scheme, the requirement for hardware sensor equipment is low, only equipment such as a rod type liquid level meter needs to be arranged in the storage tank, other various sensors do not need to be erected, and the cost of a fuel remaining amount estimation system can be reduced; meanwhile, a data driving method is adopted in the scheme, the training target is simple, the training process is stable, the model obtained after training can cover more inherent rules and modes of fuel liquid level shaking through data and feature analysis, and the estimation precision of the fuel remaining amount is higher.
