Vehicle-mounted traffic accident early warning device based on cloud edge combination

Abstract

The invention discloses a vehicle-mounted traffic accident early warning device based on cloud edge combination, which is used for solving a problem of providing intelligent early warning based on historical accident information, a current vehicle speed and road environment information before a road traffic accident occurs. The device comprises an accident data acquisition module, a cloud platform, an accident model prediction module, a vehicle-mounted terminal, a GPS positioning module, a trigger early warning module and a weather early warning module. The accident data acquisition module comprises an accident data acquisition unit and a non-accident data acquisition unit, and the accident data acquisition unit is used for acquiring accident data and sending the accident data to the cloudplatform. Weighted model training is performed through a strategy tree, a neural network, a support vector machine and a multiple regression model, advantages of multiple models are concentrated, andprediction result joint optimization and accuracy are achieved; forecast information is displayed and broadcasted by a voice through the vehicle-mounted terminal; and intelligent early warning is achieved by carrying out trigger analysis on a driven vehicle, a person and an environment.
