Abstract in Portuguese
Neste trabalho descrevemos a arquitetura e um protocolo de transmissão de dados para instrumentação dedicada ao monitoramento de parâmetros climáticos em silos e secadores de grãos. A arquitetura usa processamento distribuído e instrumentação inteligente baseada no microcontrolador 80535. O protocolo é baseado no padrão de comunicação serial multiponto RS 485 e no protocolo ISO.OSI. Atualmente. aproximadamente 20% da produção brasileira de grãos é perdida durante os processos de transporte e armazenamento. O uso de tal sistema permite medições e modelamento de silos e secadores.

Abstract in English
In this work we describes an architecture and a digital data transmission protocol for an instrumentation dedicated to the monitoring of climatic parameters of grain bins and dryers. The architecture uses distributed processing and intelligent instrumentation based on the 80535 microcontroller. The protocol is based on both the RS 485 multipoint serial communication standard and the ISO.OSI protocol. Presently, approximately 20% of the Brazilian production of grains is lost during the processes of transportation and storaging. The use of this system allows measurements and modelling for bins and dryers.
