This work shows the need to apply information and
communication technologies (ICTs) with a Programming Logic
Controller (PLC) to control humidity by remote monitoring in the
refrigeration process of an agricultural industry located in the
Mexicali Valley of northwestern Mexico, where large amounts of
orange are grown in this region of the country. This industry there
were automated electronic devices (AEDs) for humidity control in
the refrigeration area to prevent the deterioration of this
agricultural product, only that the AEDs installed inside the
evaluated company, did not operate properly due to the presence of
outdoor atmospheric pollution (hydrogen sulfide (H2S)) and oxide
sulfur (SO2)), and extreme climates in summer and winter
(variations of temperature and relative humidity (RH))in this area
of the country, that had an negative effect in indoors environments,
and damaged their electrical connections. The principal climatic
variables are the temperature and relative humidity (RH). The
humidity in the refrigerated room for the orange keep its
nutritional and physiological conditions, had to be between 45%
and 55%. As AED, did not function properly, the climate inside the
agricultural industry was not controlled, causing low and high
humidity levels. With indexes below 30% humidity in the
refrigerated room, oranges dehydrated and began to wilt, in
addition to losing weight that was considered as unfit products for
marketing. And at levels greater than 60% humidity, in this
agricultural product microorganisms formed and caused rot,
considered as a defective product and in both cases causing
economic losses. The PLC was used with a wireless system and
installed in an isolated room that only specialized personnel could
enter if necessary. This was done in this way, to avoid
deterioration of their electrical connections and that they did not
operate as the AEDs and had adequate humidity control, to
constantly maintain adequate humidity in the refrigerated room
and avoid the generation of defective products. The research was
made out from 2018 to 2019.
This work presents a way to optimize the manufacturing processes in a small biomedical industry considered in the micro-, small-, and medium-sized enterprises (SME) group and located in the Mexicali city, using a specialized software that act as design and test of a new model, being the COSIMIR (Cell Oriented Simulation of Industrial Robots) software. With this software was designed a new industrial process in a workstation separated of the main step of a manufacturing line, where are fabricated biomechanical knees pads. The process was made as a manual activity in a work station and had to be separated from the conveyor belt of the main activities, because where previously made by an automatized device that was failing continually and was delaying the delivery to the next steps of the manufacturing processes and to the customers as a final product fabricated in this industry. In this place of the company, an operation was made to organize the biomechanical knee in a plastic container with divisions and to be transported safe and quickly to other area by a conveyor belt with linear process flow. The investigation was conducted from 2018 to 2019.
In the original version of the book, the title of Chapter 13 has been changed from "The Innovation in Manufacturing Areas of Electronics Industry of Mexicali Using PLC" to "The importance of software in the electronics industry of Mexicali. The PLC case.".The erratum chapter and the book have been updated with the change.
