Sit-up exercise counting device

Abstract

The invention discloses a sit-up exercise counting device which comprises a touch display screen used for controlling start and stop of a sit-up counting function and displaying the number of sit-ups, the heart rate and alarm information in real time; the accelerometer and clock timing unit is used for acquiring an acceleration data stream in the movement process of the user; the wrist heart rate sensor is used for monitoring the heart rate of the user; the calculation unit is used for carrying out filtering processing on the acceleration data flow and carrying out real-time number statistics on sit-ups; a storage unit for storing motion data; the sound unit and the vibration unit are used for respectively giving sound and vibration alarms when the heart rate of the user exceeds the normal range of the human body; the wireless communication unit is used for transmitting the information acquired by the device to an upper computer for subsequent information processing; and the lithium battery is used for supplying power to the device. The device aims at acceleration sampling, performs sit-up motion counting based on a peak detection algorithm, and is simple in structure and efficient in calculation.

Description

Technical field [0001] The present invention belongs to the field of computer technology, in particular a sit-up motion counting device. Background [0002] Sit-up exercise is a simple equipment-free fitness exercise, usually using manual counting methods to count the number of exercises, easy to distract the attention of exercisers. The use of wearable devices to collect data on the reciprocating movement of sit-ups and the use of peak detection algorithms for counting, simple and efficient, and does not affect the user's movement. [0003] Sit-up exercise generally starts with a supine posture, the legs are together, using abdominal muscle contraction, quickly into a sitting posture, and then reduced to a supine posture, so continuously, the hand posture of the exerciser is generally divided into hands up, hands close to the ears, hands crossed in front of the chest, so that there are differences in the data features collected. At the same time, the movement state of the athle...
