and step S30, performing risk alarm, wherein the risk calculation module calculates a real-time risk value of the current transportation environment in real time according to the cargo storage information, the biological information and the environment information, and when the real-time risk value reaches a preset value, the cloud server sends a working signal to the dynamic alarm, and the dynamic alarm performs alarm.
9. The method for warning the risks in road transportation of hazardous chemical substances according to claim 8, wherein the risk calculation module calculates the real-time risk value by a coupling metric method, and step S30 includes the following substeps:
step S31, constructing a power function, defining a variable i (i ═ 1,2, … …, m) as a sequence parameter, X, of the real-time monitorij(j ═ 1,2, … …, n) is the value of the j index of the ith sequence parameter, AijAnd BijThe upper limit value and the lower limit value of the steady state lower sequence parameter are respectively represented by the following formula:
Figure FDA0002675339370000031
step S32, linear weighting, the formula is as follows:
Figure FDA0002675339370000032
wherein, UiDenotes the order contribution of the i variable, λijA weight representing each of the ordered parameters;
step S33, constructing a coupling function, wherein the formula is as follows:
Figure FDA0002675339370000033
10. the method for warning risks in road transportation of hazardous chemical substances according to claim 9, wherein in step S30, the preset value is divided into a plurality of stages, the dynamic alarm is provided with a plurality of different reminding intensities corresponding to different stages of the preset value, and the reminding intensity of the dynamic alarm is gradually increased as the value of the preset value is continuously increased.
