Resumen
The objective of this project was to develop a low-cost torque transducer that had
the ability to send data in real time to multiple devices by applying Internet of Things
communication protocols.
To begging with the development, it was first necessary to collect bibliographic
information to be aware of similar developments, the second step to follow was to
define the operating parameters under which the prototype would be designed.
Once the design parameters were defined, the quantitative comparison of the
different low-cost microcontrollers was carried out to determine which is the most
appropriate, with this step concluded, the conceptual design was carried out using
the CAD tool of the different components of the transducer.
With the preliminary designs completed, we proceeded to carry out the solution of
the mathematical models that describe the behavior of the torque and at the same
time the finite element simulation of the transducer was performed. The results
obtained from the mathematical models and the simulation results were compared
to determine if the simulation describes the effects suffered by the material.
Once the stress analysis of the transducer was completed, the process of generating
the manufacturing drawings began, and at the same time the process of developing
the communication interfaces began using the Internet of Things communication
protocol.
It was concluded that the microcontroller that is most appropriated to the needs is
the RASPBERRY PI ZERO W, because it does not require an externals module for
establishing remote connections. Mathematical models and finite element
simulations showed that the 6061 T6 aluminum alloy is capable of withstanding the
proposed working conditions and it was possible to establish data communication
between the RASPBERRY and a computer using an interface in LABVIEW using the
TCP / IP communication protocol.
