Supervisão e gestão remota de uma rede de geradores de energia eléctrica com recurso a IOT (caso de estudo: gerador diesel himoinsa CEA7)

Abstract

This report describes the process of developing a remote supervision and management system for a generator network based on IOT. Due to the lack of affordable products for the supervision of generators in Mozambique and aiming at the implementation of tools that supply safety, flexibility and quality in TVCABO, it was proposed the development of a monitoring system that possibilities the user to send commands, receive alerts and access to information about the operation of his generator group in any place of the world and in real time. Through the study of the CAN protocol, the best approach was decided to obtain the information from the CAN bus of the generators, building an embedded hardware for real-time data acquisition. Remote communication was implemented between electronic hardware of the generator set and a web page, with a supervision program. The program was developed in the PHP language, it runs remotely on a server with the intention of sending alert messages to a Telegram group/channel and information to the web page, it was also developed in this project, in order to facilitate the visualization of the results by the user. The information store is carried out in SQL Database (DB) (Maria DB), making the data available to the supervisory system. The can bus data collection hardware was designed on printed circuit boards, where the microcontroller and circuits are arranged, both powers, as well as those used for communication between the microcontroller and the bus. To send the information from the generators, sockets with the information in the Modbus TCP/IP protocol are used, using an IEEE 802.3 or IEEE 802.11 network. The developed system was validated with tests on an electric power generator, which is presented in this work. The results obtained in the tests expressed that the system is skilled in performing the operations it proposed. The printed circuits (Annex 2), supervisory software and database structure (figure 2.22), were all developed by the author, within the scope of internship. A system proficiency statistic developed vs. The previous status that is ongoing. Even so, we could find that the reaction of the company’s leaders and collaborators in relation to the results of the work carried out is openly positive. xxi It is highlighted, on the other hand, that the elaboration of this report was carried out using the Latex Platform, with a specific objective of Annex 5. In particular, it is also found that the Latex Template class was developed by the author in close collaboration with the finalist Irzelina Gune, based on the original in [1 ] and with the proper guidance of your author. The use of Latex in this work in conjunction with that of Irzelina Gune, is a pilot experience with a view to its likely adoption by Deel, the Faculty of Engineering for final course work among other possibilities
