Dumbbell fitness parameter detection method based on dynamic characteristic identification

Abstract

The invention relates to a dumbbell fitness parameter detection method based on dynamic characteristic identification, and belongs to the field of automation. The method comprises the steps that strain gauges are attached to the upper end and the lower end of a mass block and connected into a bridge to form a double-arm half-bridge measuring circuit; in the dumbbell lifting process, the strain gauges deform, the electric bridge loses balance, and a voltage signal is output; an output voltage signal is amplified by an LM358 operational amplifier, then the voltage analog quantity is converted into a digital quantity signal by an ADS1115, and then the digital quantity signal is input into a lower computer, namely an STM32 single-chip microcomputer; and the lower computer actively transmits adata instruction or receives a data transmission instruction sent by an upper computer through a Bluetooth module, and transmits the stored data to the upper computer through the Bluetooth module anddisplays the data. People can see the strength and the lifting height of themselves in the exercise process, monitoring management is achieved, the exercise strength of themselves can be changed according to actual requirements, and the best exercise effect is achieved.

Description

technical field [0001] The invention belongs to the field of automation and relates to a method for detecting dumbbell fitness parameters based on dynamic characteristic identification. Background technique [0002] In today's society, people's needs are not only enough to eat and sleep, but to pursue a healthier lifestyle. Sports is certainly one of them. Lifting dumbbells is a very common exercise in our lives. It can not only exercise the strength of our arms, but also improve the stability of the body. However, in the process of exercising, people do not know the size and lifting height of their own strength, and cannot monitor their own exercise intensity. Contents of the invention [0003] In view of this, the object of the present invention is to provide a method for detecting dumbbell fitness parameters based on dynamic characteristic identification. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005]...
