Continuous changeable stress test system

Abstract

A continuous changeable stress test system relates to a biological test device and also comprises a stress test device and a signal receiving control device. The stress test device comprises a stepping motor, a push-rod transmission device, a pressure spring device, a pressure sensor and a push plate. The power output end of the stepping motor is connected with the power input end of the push-rod transmission device, the pressure spring device is arranged at the top of the mandril of the push-rod transmission device, the pressure sensor is arranged at the top of the pressure spring device, the push plate is arranged at the top of the pressure spring device, the instruction output end of the signal receiving control device is connected with the instruction input end of the stepping motor, and the data transmission end of the pressure sensor is connected with the data receiving end of the signal receiving control device. The continuous changeable stress test system can generate continuous-changing stress and acquire biological stress and biological electro-myographic signals synchronously; and through a contrastive analysis of the relationship between biological stress generation and the biological surface electro-myographic signals, can be used for muscular atrophy degree detection.

Description

technical field [0001] The invention relates to a biological testing device, in particular to a biological testing system through biological stress and surface electromyographic signals. Background technique [0002] Traditional human-computer interaction methods are mostly realized through data gloves and video dynamic collectors. These collection methods can quickly and accurately capture the joint angles and knuckle speeds of gestures, but cannot reflect the force exerted by the hands when gripping and pressing. the size of. Surface Electromyography is a comprehensive reflection of electrical changes on the skin surface during muscle contraction. Effectively analyzing surface EMG signals and extracting precise force information will provide a more natural and convenient interactive tool for human-machine motion control. However, at present, domestic and foreign scientific research institutions are in the initial stage of research on the strength recognition based on sur...

Problems solved by technology

However, at present, when neurologists analyze the relationship between electrical signals, muscle strength and muscle tension, they mainly rely on experience to detect, and cannot quantitatively detect the relationship between surface EMG signals and biological stress, which affects the diagnosis of muscle diseases. the accuracy of

At present, there is also a lack of a continuously variable biological stress test system on the market that can generate variable stress, simultaneously collect surface EMG signals and biological stress signals, and can also save, process data and display conclusions
