Diseño de un sistema de medición de frecuencia cardíaca para la determinación del esfuerzo físico en el personal de la línea de faenamiento bovino del Camal Municipal de Riobamba.

Abstract

A cardiac frequency measurement system was designed and implemented to determine the physical effort in the workers of the bovine slaughter line the municipal channel of Riobamba. The system is based on a wireless network of Zigbee sensors with star topology, where seven workers are installed a sensor node formed by an Arduino board for signal treatment, a sensor Amped SEN 11574 for measuring heart rate, an XBee S2 module for communication and rechargeable batteries for power supply. The device allows the wireless transmission of information from each workstation to a coordinating node that centralizes information and through serial communication It transfers the data to a computer containing a graphical interface implemented in Labview: In charge of recording the heart rate, determine the level of physical load exposure through the indexes of Pain and by applying the criterion of Frimat to assess the physical effort and finally the application issues a report with the calculated values. It was possible to establish that the data packets were sent by the sensor nodes and received by the coordinator node correctly, then they were registered by the application that I valued the physical effort in a correct way, thus it was determined that the Jobs that recorded more physical effort are: eviscerated position and stun and anchorage position, while the positions with less physical effort are: post of flaying and sealing and division, with physical load levels ranging from bearable and Painful to light respectively. In conclusion the heart rate measurement system is able to assess the physical effort performed over a short period of time and within an area less than 60 meters.
