Comunicação de dados para um sistema de telemetria de baixo custo.

Abstract

Many types of equipment can present operational problems due to the lack of adequate monitoring, causing high maintenance costs. The management process that reduce those problems can be carried out through a predictive maintenance using an integrated telemetry system capable of sending alarms and monitoring the performance of the remot sites. This work is about the development of a technology that uses embedded computers with few hardware resources to automatically monitor equipment, distant or not from the controlling station, without increasing the operational and maintenance costs substantially. The telemetry system implementation applies data compression, cryptography and failure treatment and uses a low cost microcontroller for collection, storage and transmission of data in an efficient, secure and correct way.
