Self-storage portable exercise electromyographic signal collecting device

Abstract

The invention discloses a self-storage portable exercise electromyographic signal collecting device. The collecting device comprises a main control module, a gyroscope sensor, an acceleration sensor, an electromyographic measurement module, a transmitting and receiving module, an RS232 interface module and a power module, wherein the gyroscope sensor, the acceleration sensor, the electromyographic measurement module, the transmitting and receiving module, the RS232 interface module and the power module are respectively in circuit connection with the main control module. The self-storage portable exercise electromyographic signal collecting device records exercise states and the time when the electromyographic signals are generated, the analysis of the synchronous relation between the muscle movements of a person to be detected and the electromyographic signals is facilitated. All the modules are integrated on one circuit board, the size is small, accuracy is high, power consumption is small, and portability is strong. A battery of a small size is adopted for supplying power, the power frequency interference brought by using an externally-connected power source for supplying power is reduced, and cost and power consumption are reduced greatly.

Description

technical field [0001] The invention relates to an acquisition device in the field of measurement technology, in particular to a self-storage portable motion electromyography signal acquisition device. Background technique [0002] The surface electromyography signal is the biological electrical signal when the neuromuscular system is active. It is picked up by the surface electrodes, and converted into digital after being amplified and analog filtering. Myoelectric measurement or electromyography is an important method to check the function of the human nervous and muscular system, and is widely used in neurology, orthopedics, ENT and stomatology. It can provide objective scientific basis for clinical diagnosis and treatment of neuromuscular system diseases. Electromyography generally only has the functions of displaying and recording waveforms on an oscilloscope. In the early days, electromyographic signals could only be seen by photographing and developing film; later, ...
