Diseño y construcción de nodos integrables a una red de telemedición de parámetros eléctricos para el sector industrial.

Abstract

Integrable nades were designed and built to a telemetry network for electrical parameters for the industrial sector called Telenergy. The prototype consists of two essential nades that work under star topology. the Acquisition and Data Processing (NAP), which extracts information to process and transmit it to a server in the cloud, using Wifi communication technologies or General Package Radio Service (GPRS) depending on the availability and geographic location of the factory-installed meter. The Storage and Visualization Node (NA V) stores ancl displays instant and historical information on an Internet of Things (IoT) ThingsBoard platform in a graphical and interactive environment ideal for subsequent analysis processes. The platform allows users with different levels of access ancl password as administrators of the distribution company and final customers. Based on the analysis of the information in hexadecimal provided by the three-phase meter ELSTER ALPHA A3, a decoding software was developed that works under the Cl2.18 standard and allows the prototype to display inforrnatlon regarding billing and energy qualíty analysis, similar to the one supplied by the commercial software Metercat. As a result of the work, it concluded that the communication technology to transmit the data is indistinct because both have a minimum delay for viewing on the platform. Software performance simulations defined that the server supports maximum simultaneous access of 50 users and 100 nades. GPRS offers 97 .1 % of data availability. The installed prototype meets the requlrements to be a reliable and scalable system that provicles helpful information in the energy field to rnake energy optimisation decisions. It is recommended to implement a prívate server and web page to improve the storage, display and security of information.
