Diseño y construcción de un sistema de llamada de auxilio automática en caso de accidente de tránsito.

Abstract

A system of call for help in cases of traffic accidents has been designed and built, base don ADAS (Advanced Driver Assistance System). The purpose of the system is to provide desaster information to the relief agencies so that they can provide medical assistance in the shortest possible time. The system utilizes an electronic control module that receives signals from the different sensors located in the vehicle, in the particular case of this inquiry it consists of 4 sensors. The module processes the received information to make a distress call followed by a text message with the coordinates of the vehicle to the ecu 911, moreover it is posible to visualize in the vehicle the coordinates through an LCD screen. The elements that make up the system are as follows: Arduino as control module, limit switches, LCD serial display, GPS system, GSM system, resistors and switches. To develop the software it is used the compiler of the Arduino system which allows configuring the electronic system with the necessary conditions; both the software and the hardware are freely accesible. The system is able to be activated both with light strokes and with faster strokes. By testing the systen in 30 different scenarios and with the help of an additional GPS the desired objective was achieved as the calls and messages with the coordinates of the accident were correct, furthermore a reliability factor of 87% was obtained, succeeding in implementing succesfully the system in our prototype being a reliable system in different conditions and in any part of our country. The system can be implemented on a large scale in our country contributing to the safety of our compatriots on the roads. It is recommended to have the system provided with available mobile phone credit because without this factor the system does not work.
