The invention discloses an elevator real-time monitoring and grading early warning method and system based on big data. The method comprises the steps that A, a BP neural network is established; b, creating an initial database; c, BP neural network learning; d, elevator operation data are obtained; e, running data of the elevator are input; f, the risk level of the elevator operation data is judged; g, the risk level of elevator operation is output; through statistics and analysis of fault data such as people trapped in an elevator, a BP neural network algorithm is introduced to learn and train various fault data, the weight of an input quantity is continuously adjusted until output layer data meets error requirements compared with a true value, and then a learned algorithm model is applied to carry out operation calculation analysis on key data in the operation process of the elevator, so that the operation accuracy of the elevator is improved. According to the method, the corresponding risk level is obtained, risk early warning is achieved, potential safety hazards can be eliminated in time, and in the follow-up operation process, the accuracy is further improved through learning and parameter adjustment.
