Sistema de Telemetria E Telecomandos de Baixo Custo Para Medicao Remota de Grandeza Fisicas (Low Cost Telemetry and Telecommand System for Remote Measurement of Magnitude Character)

摘要

The design is presented of a telemetry and telecommunication system for the remote measurement of lab experiments. It allows the interaction of equipment that stand on an Air Bearing table with other lab equipment. It is possible to use it in situations in which man cannot be present, for it would be dangerous or could disturb the measurements. The telemetry subsystem has 15 channels, analog or digital, which are swept at a rate of 400 Hz each. The telecommand subsystem allows the sending of up to 30 different telecommands. The first prototype has already been tested with good results and it is being perfected in order to upgrade its performance and reduce the power consumption.
