摘要：Catastrophic accidents caused by the leak of hazardous chemicals in the storage and transportation process occurred frequently, in order to seek for a continuous, all-location, real-time solution for tracking, positioning the vehicles transporting dangerous hazardous materials，this paper design a track access system, which is the integration of Global Positioning Systems(GPS), Google Earth geographic information systems, the GSM information systems and computer data processing technology. The locus access system obtains the raw GPS data from truck/ship-borne positioning terminal, and then transfer to the PC through USB, at last, the PC extracts and analyzes these data and execute coordinate transformation, and map these locations which point to the GPS data on the screen, forming a locus. The accurate knowledge integrated in the system of supervision of hazardous materials transportation ensures the establishment of early warning of hazardous chemicals leakage and accurate monitoring of storage and transportation. The integrated positioning monitoring system is found flexible, reliable and accurate for recording trace of the target under practical site conditions, is a mainstream of modern hazardous goods logistics.
