Abstract

The invention provides an electromyographic signal and inertia information synchronous collection device which comprises a multi-information collection sensor, an embedded microprocessing system, a wireless multi-platform application interface, a power module and a data application platform, wherein the multi-information collection sensor transfers the electromyographic information and inertia information collected in real time to the embedded microprocessing system through a signal synchronous input interface; and the electromyographic information and inertia information are further optimized by the microprocessing system and transmitted to the data application platform through the wireless multi-platform interface in a wireless communication way. The device provided by the invention has a series of advantages such as stable communication signal, strong expansion function, light weight and easiness in carrying and operation and can be effectively adapted to the real-time synchronous collection of electromyographic signal and inertia information in motion; and meanwhile, the device meets the needs for wireless data receiving and treatment of multiple data application platforms such as PC and mobile phone at the same time, and provides great convenience to the clinical research of the collaborative operation way of limbs of human body in motion.

Description

technical field [0001] The invention relates to the field of signal synchronous acquisition, in particular to a multi-information synchronous acquisition device of human limbs. Background technique [0002] Human surface electromyography (SEMG) is a voltage sequence generated during muscle movement. Acquisition and analysis of electromyography can obtain rich information about muscle movement, including information on motor function, muscle fatigue, rehabilitation status, and movement coordination. Therefore, EMG signal becomes the best biological signal to study motion. [0003] Motion inertia information includes information such as acceleration, angle, and angular velocity. According to the information of human body inertia, it can directly describe the motion angle and motion inertia of the human body to realize motion capture. The inertial physical quantities obtained by objectively quantifying human activities can be directly applied to different fields such as motion...

AI Technical Summary

Problems solved by technology

Traditional EMG acquisition equipment has the following limitations under the requirements of new fields: the acquisition mode is mainly based on EMG signal acquisition, lacking inertial information acquisition capabilities and expandable interfaces, such as the US Noraxon 2400T-G2 surface EMG acquisition and analysis system; the acquisition environment It is mainly aimed at the acquisition of EMG signals under static movements, and lacks the anti-interference ability in motion, such as the domestic eight-channel wired surface EMG instrument CB-0810; the acquisition system often requires a fixed base station, which is large in size and inconvenient to move, and the data processing interface is sealed , unable to adapt to real-time applications in different environments, such as the TrignoMobile of the American DELSYS company
