Informatics system for supervision and control of processes with mobile devices

Resumo

Control and Automation has experienced a tendency to use wireless devices for supervision and control of different process, which also improved with the development of mobile technology. This paper shows how to develop an informatics system for supervising and controlling processes using mobile devices, implementing an architecture that uses wireless connection (Wi-Fi) and a fieldbus to establish communication with the processes. The mobile devices are based on Android which runs an application that establish communication with a computer running a server that listen all requests and sends, by RS232, the data sent by the mobile device through the fieldbus to the process. For communication between different elements of the system a RS232 protocol was used. This protocol is a modification of the original RS232 adjusted to the architecture of the system.
