Diseño y construcción de un semáforo como módulo electrónico autodiagnosticable con capacidad de generación y transmisión de alertas ante fallas.

Abstract

The objective of the curricular integration research project was to design and build a self-diagnosable traffic light as an electronic module with the capability of generating and transmitting alerts in case of malfunctions; it works with wireless communication using WIFI technology, it issues warnings when there are issues with power supply, luminaires operation, or positioning. For its design, a bibliographic review and the study of regulations were carried out; requirements were proposed; hardware, software, and structural elements were designed and selected, suitable for their implementation, and finally, It was validated. The sensor accuracy tests determined an accuracy of 98.96% and a stability of 1.4% based on the coefficient of variation. The data integrity tests verified that there are no data losses and that it can maintain a 6-hour operating autonomy in case of power outages. It is concluded that the technological device complies with the established requirements for generating alerts in case of malfunctions and can be competitive with commercial devices. It is recommended that artificial intelligence be incorporated into the device with the capacity for self-diagnosis and identification of the specific stage and element that presents a fault.
