Abstract

The invention discloses a self-storage portable motion myoelectric signal acquisition device, which comprises: a main control module, and a gyroscope sensor, an acceleration sensor, a myoelectric measurement module, a transmitting and receiving module, and an RS232 interface respectively circuit-connected to the main control module modules and power modules. The invention records the movement state and the time when the electromyographic signal occurs, which helps to analyze the synchronous relationship between the muscle action of the detected person and the electromyographic signal; each unit module is integrated on a circuit board, with small volume and high precision , low power consumption and strong portability; the use of a small battery for power supply reduces the power frequency interference caused by the use of an external power supply, and the cost and power consumption are greatly reduced.

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 human nerve and muscle system, and it 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, EMG signals could only be seen by photographing and developing film; later, EMG signals were de...
