SISTEMA DE AQUISIÇÃO DE DADOS COM COMUNICAÇÃO MODBUS

Abstract

Agroindustry converts primary products into by-products to supply the population. Aimed primarily at the production of food for the final consumer, these by-products are produced gradually walking side by side with technology, aiming at improving the production process. Unlike the industrial sector, agribusiness deals with raw materials based on perishability, heterogeneity and seasonality. The purpose of the work was to develop a low-cost device capable of meeting the needs of the agroindustry and using the industrial Modbus protocol through an Arduino microcontroller. A device implanted in the banana packaging area had read the type of fruit to be packed and the operator packing. This application sends data to the network master using the Modbus TCP/IP protocol where the information collected through the RFID reader will be treated, where the network master will control the production in order to provide essential information such as weight, fruit type, date, time and operator for the datalloger. The hardware interface will be through an Arduino microcontroller, where it performs the reading of the RFID card. The functioning was proven with tests, and the results were satisfactory, the communication with the Modbus network, the communication between the shields and the rfid reading, being then transcribed in the present work. With the system in full operation, today it is in a state of improvement to reduce shields.
