The invention discloses a strain balance temperature gradient error compensation method and system based on deep learning. The method comprises the following steps: arranging a temperature sensor on abalance to obtain temperature data and temperature gradient error data of the balance; selecting a key temperature measuring point according to the balance temperature gradient error data; finally, establishing a deep belief network DBN, setting initial parameters, and carrying out deep belief network DBN training and temperature gradient error prediction by taking the temperature data of the keytemperature measurement points as an input value of the deep belief network DBN and taking the temperature gradient error data as an output value of the network. According to the method provided by the invention, the problems of low precision and poor robustness and generalization ability of a balance temperature gradient error compensation method are solved. By selecting the key temperature measuring points on the balance, the number of the temperature sensors is reduced, and the complexity of the model is reduced; secondly, the temperature gradient error compensation method is high in prediction precision and good in robustness and generalization ability.
