The App will serve as a didactic support, since it is a graphic and technical instruction for students who wish to carry out practices related to residential electrical installations. With this module, students will be able to identify, through various previously organized practices, the types of connections and different types of accessory arrangements of a residential electrical installation, as well as identify concepts from basic to intermediate that they do not know within the topics of electricity.","PeriodicalId":197208,"journal":{"name":"Revista de la Invención Técnica","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133018956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BLDC motors require digital tools for good practices in position and speed control; as well as the power electronics for optimal performance. In order to take better advantage of the characteristics in this type of motor, a control strategy is presented that allows integrating the internet of things, to monitor and satisfy the needs when applied to a BLDC motor, which will also allow driving a submersible pump. Based on these characteristics, it will be possible to have a greater range of operation of the same, consequently, a better regulation of the speed, so that the desired water flow can be provided in the application of solar pumping systems. The results obtained validate the control designed for speed regulation in the system.","PeriodicalId":197208,"journal":{"name":"Revista de la Invención Técnica","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128699862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A concentrator with a truncated cone profile was designed to capture, transfer and diffuse sunlight, which was concentrated and transported by reflection along the walls of the system and finally projected to the interior of an agricultural building. The illuminance achieved by the system with and without concentration was compared and a significant difference in illumination levels was found. The concentrator obtained concentration factors between 1.7 and 3.6. The critical aspects that determined the concentration of natural light were the angle of acceptance (45.68º), the orientation (45º and 90º) and the reflectance of the material used (95%), in addition, it was possible to reduce the dimensions of these systems, conserving the illuminance. It was proven that this system increased the illumination of the interior space where the light did not reach naturally, improving the illuminance levels (300-500 lx), according to CIE (Commission Internationale l'Eclarige). It was demonstrated that the system represents a viable and adaptable solution for naturally illuminating buildings.","PeriodicalId":197208,"journal":{"name":"Revista de la Invención Técnica","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116330702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, PV trackers could eventually fail or have unexpected changes during tracking, requiring continuous knowledge of the solar tracker parameters at any time. It is possible to accomplish with IoT communication, which consists of implementing microcontrollers, embedded computers and network communication to transmit the information to a server. This paper presents a monitoring scheme for two-axis single pole solar trackers. In contrast to the published papers in the state of the art, it has more functionality and greater flexibility, employing a Wi-Fi connection with the Raspberry PI 4B. This monitoring scheme has been experimentally tested using the motors for a two-axis single pole solar tracker, resulting in an excellent performance along their trajectories.","PeriodicalId":197208,"journal":{"name":"Revista de la Invención Técnica","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116796481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
