Cell operation improvement using wireless human-machine interfaces

The improvement of cell operation is one of the most important concerns in primary aluminum production. Substantial gains in productivity, energy consumption, efficiency, working conditions and environment protection can be obtained with better operational procedures. This paper describes the use of a mobile wireless HMI (Human-Machine Interface), mounted in vehicles, SPC (Stud Pulling Crane) and other equipments, along with handhelds used by field personnel, to improve cell operation at CBA, Companhia Brasileira de Aluminio, Brazil. The operational improvements, the features implemented, the architecture of the solution and the technology used are presented. Some problems found and its solutions, along with future implementations, are discussed.
