Diseño y construcción de un módulo electrónico integrable a una red inalámbrica para supervisión de parámetros de velocidad y ritmo cardíaco de deportistas en entrenamiento.

Abstract

The objective of this curricular integration work was to design and build an electronic module that can be integrated into a wireless network for the supervision of speed and heart rate parameters of athletes in training. It is made up of two types of nodes, the secondary node, made up of a heart rate sensor based on the photoplethysmographic method and an accelerometer, is in charge of collecting and sending the data through radio frequency (RF) communication to the central node. The central node is in charge of receiving the data sent and transmitting it through WiFi technology to a database to later being displayed in the mobile application. The module incorporates a system for sending alert messages to the medical team when the athlete's heart rate is in a critical state. For the validation of the module, accuracy tests were carried out for the heart rate and speed sensors, obtaining absolute errors of 1.27% and 2.47%, respectively, without exceeding the errors of each sensor. From the accuracy tests, the heart rate and speed sensors obtained a coefficient of variation of 3.84% and 4.69%, respectively. In the communication tests, it is verified that the connection status is excellent at distance no longer than 130 m and the communication of the two secondary nodes is verified without loss of information. In the autonomy tests, it was determined that the battery can supply energy for up to seven training sessions of 1:45 each. From this, it is concluded that the implemented electronic module meets the requirements established for training processes and is competitive with commercial equipment with similar features. It is recommended to incorporate artificial intelligence which allows training routines to be generated automatically based on the needs of the athletes.
