Sports monitoring system and manufacturing method thereof

Abstract

The invention discloses a sports monitoring system and a manufacturing method thereof. The sports monitoring system comprises a pressure-sensitive film detection layer and a signal processing module. A first metal electrode array and a second metal electrode array are arranged on the upper surface and the lower surface of the pressure-sensitive film detection layer respectively. A first signal input end of the signal processing module is electrically connected with the first metal electrode array, and a second signal input end of the signal processing module is electrically connected with the second metal electrode array. The sports monitoring system is simple in structure, high in sensitivity, almost free of pyroelectric effect, almost insusceptible to temperature variation in an operating temperature range, sensitive to force in the vertical direction, insensitive to shear force in the horizontal direction and insusceptible to material bending in vertical pressure detection, and high-precision measurement of sports information is realized.

Description

technical field [0001] Embodiments of the present invention relate to information monitoring technology, in particular to a motion monitoring system and a manufacturing method thereof. Background technique [0002] With the development and progress of social science and technology, people pay more and more attention to their own health and quality of life, and the level of physical fitness of the human body can most intuitively show the level of personal health. The monitoring of human motion can reflect the health status of the human motion system in real time and effectively. At the same time, since the monitoring and identification information of human body contains the individual's willingness to control motion, the processing and processing of these information can also be used to control multiple Functional intelligent prosthetics, exoskeleton walkers or other human-computer interaction devices to help disabled patients or the elderly recover their health, especially t...

Problems solved by technology

Although the accelerometer can record the multi-directional acceleration data of the human limbs, it cannot provide other motion information, so the information obtained is very limited; the data glove is embedded with an inertial sensor and a bending sensor, which can identify more fine human movements, but Its disadvantage is that it is too cumbersome, and it is not suitable for the movement monitoring and recognition of amputee patients; surface electromyography is a relatively mature and widely used method for human movement monitoring. The signal of command information is then used to monitor the progress of rehabilitation activities or to control human-computer interaction equipment and myoelectric prosthetics. However, surface myoelectricity has the following insurmountable problems: it is very difficult to place the electrodes that extract myoelectricity. High requirements and high-level signal feature extraction increase the cost of work, human muscle fatigue will increase the difficulty of signal acquisition and reduce the reliability of the extracted control command signal, electromagnetic interference and changes in conductivity will also affect the quality of the signal; The force diagram method is the most promising monitoring method for compensating or even replacing surface electromyography. Its biggest advantage is that it can directly reflect the changes of muscles during exercise and has a high response speed. However, the existing It is difficult for any sensor that uses the muscle force map method to monitor human body movement in real time to have the performance advantages of high measurement accuracy and simple and light structure.
