Summary of the invention

The purpose of this utility model provides a kind of collaterals of human equilibrium analysis instrument, adopts the Skin Resistance of single chip computer measurement human body surface under the low pressure sine-wave excitation, with computer analysis and provide the quantitative analysis of viscera rise and fall of yin and yang.

The technical solution adopted in the utility model is as follows:

Scheme 1: it comprises: direct current 5V-± 10V voltage conversion circuit, sine wave generating circuit, a kind of test electrode, ac-dc converter circuit, single-chip microcomputer and peripheral circuit thereof, communication interface circuit are formed.Wherein 5V-± 10V voltage conversion circuit links to each other with sine wave generating circuit, and test electrode links to each other with sine wave generating circuit, ac-dc converter circuit, and single-chip microcomputer and peripheral circuit thereof link to each other with communication interface circuit with ac-dc converter circuit.

Scheme 2: add signal switching circuit between the sine wave generating circuit of scheme 1, ac-dc converter circuit, signal switching circuit links to each other respectively with at sine wave generating circuit, another kind of test electrode, ac-dc converter circuit.

Adopt the low pressure sine wave as measuring-signal, by be connected in the sampling resistor of measuring on the loop obtain to flow through human body alternating current and convert DC voltage to; Adopt RS232 interface or USB (USB) interface and computer (PC) or individual palm PC (PDA) to carry out communication; Power supply utilizes the USB mouth of PC (or PDA) or PS2 mouth to obtain; As increasing under the situation of signal switching circuit, Skin Resistance that then can a plurality of positions of one-shot measurement human body.

The useful effect that the utlity model has is:

It adopts the Skin Resistance of single chip computer measurement body surface under the low pressure sine-wave excitation, and single-chip microcomputer is delivered to computer by serial port with data and analyzed and provide the dirty rise and fall of yin and yang quantitative analysis of human body internal organs and hospital, diet-therapy health-preserving suggestion etc.Because adopt the less sine wave signal of amplitude, human body reacts without any discomfort, but repeated measure in a short time, and measurement result is provided by computer, has avoided subjective influence.Measuring device is designed to portable, utilizes USB mouth or the power taking of PS2 mouth of PC or PDA, adopts serial communication with computer, can use on any one PC with serial port or PDA.Under the situation that increases signal switching circuit, once can measure the Skin Resistance at a plurality of positions of human body.
