Diseño e implementación de un sistema embebido para el monitoreo remoto y local de parámetros eléctricos, temperatura y humedad, en las UPS EATON serie DX, orientado a la reducción de costos de la empresa UPSISTEMAS S.A.S.

Abstract

The health, telecommunications and industrial sectors, among others, handle processes that require uninterrupted energy supply. To ensure continuous energy flow, some companies hire or rent UPSs from third parties, saving on implementation and maintenance costs. Contracted companies must continuously monitor different parameters, which involves additional investments in network cards supplied by UPS manufacturers, which often have a high cost. This document presents as an alternative to the monitoring solutions presented by the manufacturer, the design and implementation of an embedded device that collects and integrates the parameters supplied by the UPS along with external measurements of electrical and environmental variables. In the tests carried out, the prototype allowed the visualization of electrical variables and operating states recorded internally by the UPS. For its part, the metrology system allowed through the use of 6 sensors, the measurement of 4 electrical variables and 2 environment variables (temperature and humidity). Additionally, the integration of remote monitoring or IoT could be verified, implementing the Grafana and thing speak tools. Comparative tests were carried out with certified tools to verify the veracity of the measurements and subsequently the prototype was left in operation within 3 continuous days with 24-hour monitoring allowing the analysis of the data obtained. Compared to commercial monitoring alternatives, including network cards suggested by the UPS manufacturer, the embedded device implemented reduced monitoring costs.
