Implementación de un Sistema de Adquisición, Supervisión y Control de Datos (SCADA), mediante comunicación 3G para la empresa “RIO SOLAR SMART Energy” de la ciudad de Riobamba.

Abstract

It was designed and implemented the acquisition system, supervision and data monitoring (SCADA) through communication 3D for the company “Rio Solar Energy” of the city of Riobamba. The scientific method was used for the design of software and hardware. The system consist of two type’s devices, one programmed as a client that was installed in the solar heaters, and other server installed in the monitoring station and control. The client device acquires the data of temperature and level of water, and then sends through network 3G to the server, in addition gives orders of control to each solar heater; server device collects the data received from the client device and sends them through serial port to the central computer, human machine interface (HMI) developed in LabVIEW, receives and interprets the information and manages it in order to monitor and control the operation of solar heaters and additionally stores a record of the behavior of the same. Also the system allows communicating to the users of the solar heaters about possible fault conditions on the solar heater through message of text. A comparative analysis was made of solar heaters, before and after the implementation of the SCADA system, observing absence of a control system that keep the equipment safe from damage front variations, in addition to not being provided with a system of alarms and monitoring. This problem was solved, using the system implemented, presented today an automated system with capacity of remote monitoring and of alarms facing failures, in addition to having an automatic control system. The SCADA system has allowed reducing the cost invested in maintenance and repair in a 77%. It is recommended that does not manipulate of direct form the solar heater and its devices, only through the central computer.
