New energy automobile safety early warning method and device based on Internet of Things

The invention provides a new energy automobile safety early warning method and device based on the Internet of Things, and relates to the technical field of the Internet of Things, and the method comprises the steps: carrying out the correlation analysis of historical accident data and historical operation parameters of a new energy automobile, and obtaining the correlation degree of each historical operation parameter and historical accident data through analysis, the maximum parameter of safe operation is predicted through the correlation degree, the historical accident data and the historical operation parameters, the safety range of the operation parameters in the automobile operation process is determined, and then whether the parameters are within the safety range or not is judged by obtaining the operation parameters of the new energy automobile in operation. And early warning is carried out when the automobile operation parameters exceed the safety range, so that stable operation of the automobile is
