An optimum solution for telemetry of distributed wells in South of Tehran

Some distributed wells located in south of Tehran planned to be controlled locally and also from control center. One safe control method is designed for each well by means of PLCs. For overall process purposes one main controller designed for control center and wells data are logged in a server. Two operators can control and monitor wells from control center by means of two operating station. Communication backbone to exchange data between wells and control center is studied. Offline dial up solution using polling and interrupting method is chosen for this purpose. The most important part of our design is software layers and interfaces used for easy and optimum communication.
