Lower section；Inductance sensor is connect with induction coil, and for acquiring the inductance value of induction coil, microprocessor is for obtaining inductance biography
The inductance value that sensor measurement obtains, and the size of inductance value is compared to judge current pose by inductance estimation circuit.
A kind of detection system perceiving position chanP on bed, it is characterised in that: its detection method are as follows: induction coil
Inductance value is fixed value, a, when human body lies low, since the area that lower induction coil is carried on the back in human body back covering is big, induction coil
The equivalence value of inductance is opposite to become larger；B, when human body is lain on one's side, since human body area coverage of the area on induction coil of lying on one's side is small,
The inductance equivalence value of induction coil becomes smaller to lying low；C, when human body does not lie in induction coil, the inductance value of induction coil is
One original fixed value, microprocessor pass through lie low, equivalent inductance value of lying on one's side with respect to the original inductance value of inductance coil variation
Operation carrys out multilevel iudge posture, obtains three kinds of situations that human body lies low, lies on one's side, leaving.
Compared with prior art, the invention has the benefit that using the electric conductivity and conductor of human body to coil inductance
Or the influence of capacitance, human body lies low, the difference of area coverage lain on one's side on inductance sensor, caused inductance capacitance value
Different numerical value, lying low, lie on one's side and leaving for human body is determined through microprocessor；The wearable device on human body is not needed, it is real
With reliable, comfort is high.
