Implementación de un prototipo electrónico para el monitoreo y control del nivel de glicol en una salmuera de helados mediante tecnología OPC para la microempresa “Helados Mi Chiquito”.

Abstract

The objective of this curricular integration work was the implementation of an electronic prototype for the monitoring and control of the glycol level in an ice cream brine machine using OPC technology for the microenterprise "HELADOS MI CHIQUITO" avoiding the waste of glycol, which is the substance Basic for freezing ice cream. The proposal and design of the electronic prototype contains four blocks: storage in charge of the glycol collection for filling in the vat of the brine machine, instrumentation, control in charge of the acquisition of data from the ultrasonic sensor to the programmable logic controller to emit signals to the actuator and level supervision, finally, the communication block referring to OPC technology for the SCADA system using LabVIEW. For the validation of the prototype, four tests were developed to verify its functionality based on: validation of the Jsn-sr04t ultrasonic sensor and the Pt-100 temperature sensor, demonstrating that neither exceeds the allowable error of ±1.0 cm and ±1.0 ° C, respectively; the second to verify stability through the relationship between temperature-time, distance-time; The third test verifies the operation of the GSM and PLC-LabVIEW communication by analyzing the latency time and in the fourth test the electrical consumption that the ice cream salting machine will generate monthly with the electronic prototype is analyzed. It is concluded that the microenterprise has a saving of 32.02% by not acquiring an existing automated ice cream salmon machine in the international market, the electronic prototype reduces glycol consumption and does not exceed electrical energy consumption. It is recommended to incorporate an ERP system to generate the order for glycol directly from the supplier, considering the incorporation of a level sensor in the storage tank.
