The riding speed, the duration of the dangerous behavior, and the dangerous behavior performed are all proportional to the danger level. The duration T of the dangerous behavior and the current riding speed V1 cannot exceed a certain threshold. When the two sufficient conditions of T>6s and V1>10m / s are met, the danger recognition module sends a braking command; The step S2 further comprises the following steps: Step S21: The dangerous behavior of the rider is identified, and at the same time, the scanning detection module of the front of the vehicle forms an infrared detection barrier to scan and detect the environment in front of the rider; Step S22: using the radar detection submodule to perform radar detection on whether the scanned object is moving; Step S23: according to the result of the analysis and judgment by the object analysis module, the trajectory judgment module judges the object's movement trajectory, and the speed analysis submodule analyzes the movement speed of the target object from the radar detection; The step S3 further comprises the following steps: Step S31: the infrared distance measuring submodule uses infrared rays to measure the distance between the object and the rider; Step S32: the route analysis module analyzes the probability of predicting an accident; Step S33: According to the predicted situation, the calculation and analysis module analyzes the information collected by the information collection submodule to calculate the current vehicle speed required; In step S32, the calculation formula for predicting the accident is: Among them, t is the time value of the predicted accident at the current speed, t>0, C is the distance between the rider and the object measured at the current position, V1 is the original speed of the rider, V2 is the speed of the object whose trajectory intersects with the rider per second, and N is the probability of an accident between the rider and the identified object at the same time. When V1>V2, the accident must satisfy both formula 1 and formula 2. When V2>V1, the accident must satisfy both formula 1 and formula 3. ε is the conversion coefficient. The faster the predicted time of an accident, the higher the possibility of an accident. In step S33, the calculation formula of the current vehicle required speed V0 is: Among them, V0 is the speed that can avoid accidents. The identified danger level W and the probability N of an accident between the rider and the identified object at the same time are inversely proportional to the current vehicle speed V0. The higher the danger level, the slower the vehicle speed V0. <V1。 2. The big data-based perception recognition storage terminal system according to claim 1, characterized in that: The step S4 further comprises the following steps: Step S41: the information receiving submodule receives the transmitted instruction and the information of the analysis result; Step S42: the information identification submodule identifies the current dangerous situation based on the received data and responds accordingly; Step S43: According to the response, the execution control module controls the vehicle.
