Design and Implementation of Web Services Oriented GPRS Remote Meter Reading Model

Based on the research on a power company remote meter reading system and for the purpose of enhancing the management level of the meter reading of power companies, the Web services oriented GPRS remote meter reading model is suggested. By means of the Web services technology, the model is integrated with various related heterogeneous systems and application seamlessly; simultaneity through the JNLP (Java network launch protocol) specifications, the deployment and maintenance of the system can be simplified much; The real-time and reliable front-end based on the GSM/GPRS (global system for mobile communications/general packet radio service) network is implemented by Java multi-threading and and socket technology. As an example of reading "the present three-phase voltage and current" of one remote transformer meter, this paper will give the model design and key codes based on the latest Java Web services specifications JAX-WS (Java API for XML-based Web services) and the JNLP specification. The model designed meets the actual requirements well, and accords with the standards of State Grid Corporation. The model has a favorable application in the actual remote meter reading system of the power companies.
