Diseño de un sistema electrónico para el bloqueo de vehículos de transporte público basados en la medida de alcohol por litro de sangre en los conductores.

Abstract

The objective of this research work was to design an electronic system for the blocking of public transport vehicles based on the measurement of alcohol per liter of blood in drivers. For the development of the system, an MQ-3 alcohol sensor was included that allowed to measure the level of alcohol and an Arduino that is the brain of the device, coupled in a structure which was developed in SolidWorks and elaborated in a 3D printer. The methodology used is analytical since we start from a whole that in this case are traffic accidents, in this way we learned the causes that originated, deductive because the hypothesis was linked to the results collected from the execution of the device and synthetic since at the end of the bank of tests and feasibility assessments it was possible to issue conclusions and recommendations. As results, it was obtained that the accuracy of the measurement of the electronic system is reliable for the measurement of alcohol in people and can be implemented through national public policies that supported the elaboration of the project. It is recommended to monitor the drivers of urban public transport in the matter of consumption of alcoholic beverages during their work days, to safeguard the safety of users and other road users.
