The invention discloses a dynamic risk early warning system for dangerous goods road transportation based on internet of things technology, comprising a vehicle-mounted unit, a vehicle-dispatch waybill module and a risk assessment unit, wherein the vehicle-mounted unit comprises a vehicle positioning module, a vehicle running parameter acquisition unit, a driver parameter acquisition module, an information processing and communication module and an alarm module; the vehicle-dispatch waybill module comprises a vehicle basic information module, a driver basic information module, a cargo information module and a transportation route information module; the risk assessment unit comprises a geographic information analysis module, a transportation accident probability assessment database, a transportation consequence assessment database and a transportation risk assessment database. The risk assessment result is compared with a acceptable risk threshold value, and if the acceptable risk threshold value is exceeded, an early warning will be sent out by the system. The dynamic risk early warning system for dangerous goods road transportation can assess the dynamic risk of the dangerous goods road transportation in real time, and send out an early warning when the risk exceeds the preset threshold value, so that intelligent auxiliary supervision of the transportation risk is realized, and the dangerous goods transportation management is improved.
