Integrated smart dc ac energy meter supported in IoT network

Energy measurement together with the processing of process data in industrial plants is an area in which the contribution of electronics is great nowadays. New hardware and software solutions of electronics have been implemented in these areas. They provide the opportunity for industrial plant data to be measured, processed, stored, visualized and distributed. In these procedures, the tendency is towards digital processing of signals from measured quantities, although there are also solutions in which analog processing is also present. In this processing of process parameters, it is essential that users have timely and accurate information about the measurement data in their industrial complex. Driven by the need for measurement, visualization and storage of process parameters, modern electronic systems enable processing and storage of measurement data on site and their transmission to the GSM and IoT network. On the other hand, the application of sophisticated electronic systems is noticeable not only in power plants, but also in healthy and quality food industries, such as agriculture. This tendency arises from the emergence of a large number of independent plants in agriculture that are remotely located and require independent power supply as well as transmission of their process parameters over a distance. Guided by these reasons, in this paper has designed an electronic system that offers a solution to the problem of supplying electricity to such plants. The paper provides a solution for measuring the two components of energy systems, i.e. measuring DC and AC energy. The solution, in addition to measuring, visualizing and storing on-site, also provides the possibility of transferring them to the IoT network. The measurement data for DC and AC energy are visualized locally on LCD screens and stored on an SD card, and are remotelu transmitted to the IoT network and visualized on a mobile device.
