The invention discloses a tunnel boring machine host dismounting device safety operation early warning method and system, and the method comprises the steps: carrying out the preprocessing of data collected by all sensors, and obtaining a safety state coefficient through the fusion of an analytic hierarchy process and an entropy weight method; taking the safety state coefficient as input, establishing different types of prediction models, and predicting the safety state coefficient of the next stage; meanwhile, a plurality of combined prediction models based on the minimum error square and the least square method are established according to mutual combination of different types of prediction models, and the optimal combined prediction model with the best prediction effect is selected as a safety early warning model; and predicting a safety state coefficient of the later dismounting device based on the safety early warning model, and comparing the safety state coefficient with the operation alarm degree and the risk level of the dismounting device to determine whether the dismounting device continues to operate or not. According to the invention, effective early warning can be carried out on the safety condition of the dismounting device during operation, and the operation safety of the dismounting device can be ensured.
