Design of a control and monitoring system for pollutants in a handcrafted footwear factory

Abstract

Autonomous systems provide a new approach to environmental quality control in the labour market, especially in jobs that expose the employee to concentrations of pollutants, which, if constantly exposed, can cause damage to the employee’s health and well-being. Therefore, this work presents a system of control and monitoring of pollutants in an independent way for a handmade footwear factory. For the development of the design, the VDI 2206 methodology was used, where the technological information, control design and system integration are presented. All this will allow the system to perform a good collection of information of the main environmental parameters to then be displayed on an HMI screen in real time, also the system has a PLC controller to activate the air conditioning instruments according to the information received in order to maintain the maximum permissible parameters of pollutants, which are a temperature between 30 ° C and 35 ° C, a relative humidity between 30 % and 70 % and an exposure of VOC between 0.50 ppm and 0.70 ppm. In this way, the system prevents the occurrence of diseases caused by unintentional exposure to pollutants.
