Application method of the invention is：
When being detected, testing equipment is worn on motive position by user, such as at wrist, the arm bicipital muscle of arm,When human body motion when, muscle stretch generation electromyographic signal first through electronic watch skin electromyographic electrode gather, the myoelectricity after collectionSignal filters the interference signals such as Hz noise by amplification and filtration module, retains 10-500Hz signals, the detection of muscular fatigue degreeFiltered electromyographic signal is amplified in ADC collections in governor circuit, converts thereof into data signal storage, and by muscular fatigueDegree detection algorithm circuit, calculates muscular fatigue degree, and the electromyographic signal data after analyzing and processing are by Bluetooth transmission to mobile phone terminalShown in real time.The supracutaneous motion state detection module collection body motion information of electronics is integrated in, is sent tired to muscleLao Du detects governor circuit, and treatment is analyzed by motion detection algorithm circuit, exercise data interface exercise data, andShown by Bluetooth transmission to mobile phone terminal.Myoelectric information after being moved through, fortune is drawn by the change of myoelectric information before and after motionMuscular fatigue degree change after dynamic.
Compared with prior art, the beneficial effects of the invention are as follows：
First, flexible circuit board design amplifies and the detection master control of filter circuit, motion state detection module and muscular fatigue degreeCircuit, small volume, high precision can effectively suppress human motion interference, be easy to human body long periods of wear, reduce equipment cost.
2nd, flexible PCB can improve the ductility of this testing equipment, and signal to noise ratio is high, strong antijamming capability, can be comparedTraditional needle electrode certainty of measurement higher.Flexible PCB is connected on electronic watch skin electromyographic electrode, so as to ensure in human bodyThe body surface that can also be fitted under motion state does not fall off, and electronic watch musculus cutaneus electricity electrode contact noise inhibiting ability is strong, can greatlyReduce and changed with Skin Resistance by the caused electrode of motion and vibration of people, improve certainty of measurement.
3rd, motion state detection module detects the axial information of human motion, can make comparative point with electromyographic signalAnalysis, is easy to people to more clearly understand the muscular fatigue degree situation under corresponding sports position, improves this equipment and is led in medical rehabilitationThe practicality in domain.
4th, being wirelessly transferred for detection data can not only be realized using blue-tooth technology, and using host computer to detection numberAccording to being stored, contrasted by the front and rear phase of electromyographic signal, electromyographic signal ANOMALOUS VARIATIONS is found early, be wearer's early warning muscleThe diseases such as atrophy, myasthenia, supervise wearer's seeking medical attention early.
