Construcción de un prototipo electrónico inalámbrico de supervisión y control de velocidad para vehículos que se desplazan en carretera según normativas ecuatorianas.

Abstract

The research aimed to build a wireless electronic prototype for speed supervision and control for road vehicles according to Ecuadorian regulations, it works with a positioning sensor that through programming allows to establish the speed and the coordinates in which a vehicle is located; it works with the ESP32 development card which controls the speed limits allowed for circulation according to current regulations. The prototype has sound and visual warnings that present two alerts to the driver at 15-second intervals to then proceed with the registration of the offense committed, which is shared through GSM communication in written form through an SMS and the WhatsApp to the owner of the car. The prototype has the capacity to store all the offenses committed in a cloud database, which can be viewed through a free access web page for both offenders and control personnel. The prototype presents a non-invasive design for the vehicle, it is powered by 12V from the vehicle's battery and has two 8800mAh lithium batteries that give it a four-hour operating autonomy. As a result of the precision tests applied to the prototype sensors, a maximum relative error of 2.20% was determined, which is considered acceptable according to the authors. From the stability tests applying the T Student method, an error value of less than 5% was obtained as a result, which validates its operation, thus meeting the objectives. It is concluded that the prototype can be an aid tool for speed control and its design is competitive with commercial devices by presenting better features. It is recommended to extend the testing times to find possible improvements to the design.
