Abstract

This research is focused on the design and implementation of a telemetry system using point-to-point technology to monitor the data of the solar vehicle in order to check the correct operation of the solar vehicle by means of sensors that will enable to verify parameters such as solar vehicle speed, vehicle RPM, temperatures of the batteries of the solar vehicle, voltage of the batteries of the solar vehicles, loading and unloading of solar panels, environment temperature, passenger compartment temperature, humidity, pilot heart rate and the wind speed. The methodology followed in the development of this research was the "SCADA" system, which makes possible to visualize the correct functioning of the solar vehicle in real time. The electronic control system was developed in Arduino, a free hardware based on a board with a microcontroller that enables the operation of the electromechanical system. For the transmission of data, it was used the Xbee module, a wireless communication module that enables the interconnection and communication between devices. The interface used in the design of the system is a Nexion Tactile screen due to its compatibility with the pilot and the technicians in charge of monitoring the solar vehicle in real time. In order to determine the reliability of the telemetry system, 6 tests and experimental tests were taken for the 10 parameters to be verified, determining that the data are reliable and behave in a normal way, there are exceptions in certain parameters such as speed, RPM and load of solar panels. These variations are typical of vehicle handling, which do not represent an error in data monitoring. It is concluded that the solar vehicle monitoring and control communication systems have a reliability of 90% and meet the requirements found in the regulations for the competition of the Atacama Solar Race. In order to check the reliability of the telemetry system, it is recommended to verify the data of each measurement parameter.
