Prototipo para obtención de firmas eléctricas utilizando raspberry pi. 3

Abstract

Measuring instruments are used as the main tool for data acquisition and monitoring of electrical consumption. This fact is justified because nowadays information is the most valuable and necessary asset to predict the behavior of physical phenomena in the real world, it is possible to monitor electrical equipment that are in active state of electricity consumption in addition to those who are at rest, in this way you can get the data through the measuring instruments for storage. Currently there is a variety of intelligent sensors, they can be used as a measuring instrument for data acquisition, controlled through software on a computer, which allows the control, adjustment and calibration of the sensors to meet the needs of any project. All stored information can be analyzed and corrective actions can be executed in case you need to decrease the number of energies consuming devices, optimizing their utilization and eliminating unwanted energy activities. Currently there are optimized intelligent devices that reduce the percentage of error when monitoring electricity consumption to obtain the data, there are many options available in the market for devices that allow monitoring of electricity consumption such as smart plugs, these abound in the international market, they can be purchased on request although their acquisition is not economical, they fulfill their function and are efficient when reading data. The disadvantage arises when you want to measure more devices within a house, it would be necessary to acquire a device for each appliance which is not economical if the energy consumption of each one is controlled. The purpose of this proposal is to design and implement a prototype for obtaining electrical signatures of electronic equipment, which allows to measure and transmit the data for storage using the Raspberry Pi minicomputer, the current sensor PZEM-004t, so as to obtain the values of active power and reactive power that are necessary to plot the electrical signatures of electronic equipment measured.
