Data acquisition device and method for hanging piece type strength trainer

Abstract

The invention provides a data acquisition device and method for a hanging piece type strength trainer, and the device is characterized in that the device comprises two parts: an RFID tag and an RFID reading unit; the RFID tag is pasted on a barbell disc and records the number and weight information of the barbell disc; the RFID reading unit is fixed on a movable support arm of the strength training device and moves together with the movable support arm of the strength training device; and the RFID reading unit comprises an RFID reading module, a wireless module, a gyroscope, an accelerometer,a peripheral circuit, an antenna, a PCB, a battery and a shell. The RFID reading module, the wireless module, the gyroscope, the accelerometer and the peripheral circuit are welded to the PCB, the battery is connected with the PCB through a wire, and the antenna is connected with the RFID reading module through a wire. And the PCB and the battery are fixed in the shell.

Description

technical field [0001] The invention relates to the field of fitness equipment, in particular to a data acquisition device and method for a plate-mounted strength training device. Background technique [0002] Strength trainers are common equipment in gyms and fitness centers, and are effective tools for strength training and fitness shaping. With the application of the Internet of Things and big data, the collection of fitness data has become an important direction for the intelligence of fitness equipment. For the plug-in counterweight type strength training device, there are already mature solutions for data collection. Whether it is the Hall switch collection method or the photoelectric switch collection method, it can effectively collect data such as weight, times, and speed in strength training; but For the data collection of the plate-type strength training device, there has been no economical and reliable collection method. There has been an acquisition scheme that...

For the plug-in counterweight type strength training device, there are mature solutions for data collection. Whether it is Hall switch collection method or photoelectric switch collection method, it can effectively collect data such as weight, times, and speed in strength training; but There has been no economical and reliable collection method for the data collection of the plate-type strength training device

There has been an acquisition scheme that uses the camera to identify barbell plates through image recognition. Due to the high hardware cost required for image recognition, and the inability to accurately and effectively collect the weight displacement data of the strength trainer, it cannot be applied in actual production.
