Network and Sensor Technology
The aim of this project is to conduct a scoping study of various sensor and network technologies for integrated plant systems. More precisely, to investigate the nature and performance of various combinations of modern sensor and network technologies in coal preparation plants.This study will help establish design and performance criteria of sensor and network technologies. This knowledge will highlight the potential to retrofit existing systems, and to assist with the purchase of new systems. Eventually, though the reduced cost and reliability of sensor and network infrastructure, preparation plants will become increasing automated.In the coal industry, improved computer models of process and control technologies has brought major benefits for the operators of coal preparation plants. However, a truly autonomous plant requires an integrated approach to all aspects of its operation. The software for mine management, process control, and plant maintenance is already available in many forms, and improvements are taking place continuously. Typically these systems comprise of disparate specialised applications that are not integrated. At present an integrated systems approach is not feasible, due in part to design incompatibility of commercial turn-key systems.The cost of sensor technologies has plummeted in recent years, however, the cost of networking sensors has actually risen as a consequence of increased system complexity and performance demands. Technological developments that enable integration of disparate sensors and networks is occurring, but the best and most efficient solutions for the coal preparation plant have yet to be determined.This project will evaluate:*The state of modern fieldbus technology, including industrial ethernet*The suitability of commercial middleware, to bridge disparate systems*The performance of wireless communications in the coal prep environment (Bluetooth, WiFi, AdHoc RF networks, GSM, SMS, GPRS)
