Abstract

This research project intends to define the necessary characteristics for developing a digital monitoring system. The equipment must monitor and process the acoustic signals produced by the system and communicate with the control of machine-tools in order to correct problems or improve working conditions. The research intends to establish precisely the most appropriate methods of handling the acoustic signals and monitoring strategies for industrial use. The development of a hybrid filtering system will also be developed, as well as frequency analysis software. Sensis was founded in May 1995 by postgraduate students and former students of the São Carlos Engineering School, who carried out research into the monitoring and automation of the process of rectification. Sensis developed a first product, called BM12, which is an acoustic emissions monitor using similar technology. In using and monitoring the BM12, Sensis observed the need to develop a new digital technology system, aimed at increasing the reliability and quality of precision manufacturing operations as well as lowering their costs. The digital system will enable the system to interact more with the machine and make it easier to install. (AU)
