APPARATUS FOR DETERMINING POWER OF PERFORMED PHYSICAL WORK

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medical equipment. Device for determining power of performed physical work includes strain gauges, analogue-to-digital converter, microcontroller, module Wi-Fi. Information source is a platform for performing exercises – platform scales. Platform for performing exercises is configured to record variable pressure on platform, supply of alternating electrical signal to input of ADC, with function of preliminary amplification and digitization of analogue signal, is mechanically connected to array of bridge strain-resistive sensors. Bridge strain gauges are connected in parallel. ADC input accommodates a capacitor. Capacitor serves as simplest C-filter, reduces induced noise and provides accuracy of measurements. ADC chip is connected to the microcontroller through a serial SPI interface, performs preliminary processing of data and sending it to a computer system via wired or wireless interfaces, visualization and storage.;EFFECT: higher accuracy of determining power of performed physical work by determining body weight in dynamics by recording variable pressure in digital numerical expression.;5 cl, 3 dwg
