Core is adjusted massage head according to previously measured back curve when massaging, and to ensure that massage force is uniform, avoids protrusion
Place by it is too heavy, fall in place by it is too light.
The method of detection human body back curve has following several at present：Detect motor speed, detection current of electric and detection
Massage head pressure.The method for detecting motor speed is to eject massage head with constant smaller speed, when massage head touches the human body back of the body
Stop when portion, it is back height as to detect back and write down current ejection amount.Detect current of electric method, be ejection by
Massage head after head of rubbing touches back, and motor load increases current of electric and increases, when detection electric current reaches threshold value after record current top
Output is back height.The method for detecting massage head pressure is that pressure sensor is added in massage head part, when collected pressure
Power reaches setting value, and it is back height as to detect back and write down current ejection amount.
The defect of the method for detection motor speed and detection current of electric is to detect and cannot continuously detect in real time,
When massage head is in massage human body back song can not be detected by detecting motor speed and detecting the variation of current of electric simultaneously
Line only individually detects a human body back curve, so cannot achieve real-time detection before massage program starts.Due to each
Detection is required for after being zeroed massage head ejection amount moving down into next point ejection, is depicted so cannot achieve continuous detection
Continuous back curve.Although the method for detection massage head pressure can realize detection in real time and continuous detection, sensor cost
It is high.
It is back height since above method is all record massage head ejection amount, and the acquisition precision of ejection amount is by code-disc
Precision determines that and the precision of code-disc is not high enough, thus the common defects of the above measurement method be all measurement precision it is not high.
