Design and Realization of a Flexible Overland Freight Monitoring System for Hazardous Chemicals Based on Multi -Network

Abstract

Flexible Overland Freight Monitoring System for Hazardous Chemicals, with the functions of tracking and localized, is designed. Sensor network, which is the integration of sensor technology, embedded and wireless technology, is a novel technique about data acquiring and processing. Some technologies cooperated with diagnosis are included, such as sensor, data collection, signal analysis, data processing, database, and net transmission. To achieve the hazardous chemicals from the production, storage, transportation to the whole process of remote real-time tracking and monitoring，This system receives real-time GPS position data, and sends it to internet through GPRS net. And with the technique of GIS, it realizes managing and monitoring tankers at the watching center. The converter has interfaces of GSM protocol and can send the control information and data of the control center to any terminal in the GSM network. Likewise the remote data can be transmitted to the control center with the converter. Controlled by central control system, the system can operate automatically and continuously.
