GPRS based remote data acquisition and forecasting system for long-distance natural Gas pipeline monitoring

摘要

Wireless based data acquisition solutions are widely used in many fields like structure monitoring, transportation or environmental studies. This paper presents a General Packet Radio Service (GPRS) based remote data acquisition and forecasting system, which monitors the geological disasters along the natural gas pipeline under the ground. The field data terminal units (DTU) collect data from the sensors installed on the pipe, and transmit the data by GPRS module to the server in the control center. The server processes the data, broadcasts on the website, and forecasts abnormal variation in time. Three years' operation in site shows the system is effective and feasible.
