Resumo:
Integrated system for monitoring products stored in silos. Grain production has been growing and producers are looking for methods to effectively
conserve the stored product. The technology grows mainly in the agricultural activity and
with that the change of behavior of the producers in adapting to the market. The main
factors that interfere with the quality of the grains during storage are their temperature and
water content, and are related to the product's respiration and the presence of
microorganisms. The incorporation of digitalization resulted in the concept of Industry 4.0,
characterized by the integration and control of production from sensors and equipment
connected in a network and creating cyber-physical systems and making the use of
artificial intelligence feasible. In this sense, this research aimed, through instrumentation,
the implantation of low cost sensors and microcontrollers in grain silos, to develop an
application to assist the producer in the management decision making of his business. A
grain silo was constructed in a reduced metallic model and as instruments for obtaining
data on humidity, temperature, gases, load and height, sensors were used, connected to a
microcontroller with Wi-Fi connection to Blynk©. With this, the Integrated Storage Process
Monitoring System was created to visualize the data. The silo volume was calculated and
the physical properties of the corn were determined and after the tests were performed with
fresh corn with openings of 1/4, 1/2, 1/3 and 1/1 of the hopper in 4 repetitions and the mass
flow calculation was elaborated. The results showed that, the developed prototype fulfilled
its functions, was able to obtain data, store and supply safely and quickly to the developed
system that proved to be viable for use in poultry and computational applications. The
lowest unloading flows of corn were recorded when the hopper with a 1/4 opening was
used. The mass flow showed proportionality between the openings used in the hopper in
the tests and their repetitions. The average discharge time between all tests and the hopper
openings adopted was 27.15 seconds.
