This psychological tester adopts the pick off of latest domestic grain husk, and the pulse that its is gathered, breathing, three and reliable in parameters of skin electricity are undistorted.The present invention compares with the psychological tester of the U.S. has following advantage:
1. the pulse transducer of U.S.'s instrument adopts oversleeve sphygomanometer formula, pressurization 60-90mmHg, and the measured has intensive constriction, and arm can be numb, can not the long-time continuous test.This psychological tester adopts voltage sensitive sensor, wears in wrist arteries and veins place, does not have constriction, but the long-time continuous test.
2. the respiration pickup of U.S.'s instrument adopts pneumatic or liquid-type, and is fragile, causes gas leakage, leakage, influences sensitivity; And this instrument adopts tension pick-up, and stable performance is survivable.
This psychological tester also has following advantage: this instrument is because software makes test process flexible, and range of accommodation is wide, can adopt particularly plot method of testing of various test, thereby easy to use, the accuracy height; This instrument problem is adjustable blanking time.U.S.'s instrument is fixed interval 20 seconds then, can't test as the long-time unstable rule of tested person's psychology; This psychological tester problem is provided with number and does not limit, and U.S.'s instrument then limits and can not surpass 14, and this has just limited effective utilization of some method of testings.
Safe in utilization on human body for guaranteeing this instrument, in strict accordance with the security regulations requirement, forceful electric power is confined to very little zone after going into machine during design, and the electrode output serial connection insurance resistance in the gain of skin electricity breaks down also in the safe voltage scope even guarantee.
This instrument has unique startup self-detection function, but self check and human body electrodes in contact running voltage and demonstrate concrete numerical value by voltmeter whether in prescribed limit, change normal operating conditions then automatically over to.
This software concentrates on the computer screen bulk information, and mouse-based operation is prepared the preceding desk of loaded down with trivial details measurement, test operation is surveyed the back and is passed judgment on by the computer assisted processing, has got rid of question form originally, manually operated toolses such as sizing make measuring process convenient, accurate, quick.

Embodiment:
The psychology that people are produced when the incident of saying mental change when detecting a lie and people's memory is brought up again stimulates the variation that must cause some physiological parameters such as skin electricity, pulse, blood pressure, breathing etc., they generally only are subjected to neural restriction, and are not subjected to the control of brain mind.Psychological tester select to measure skin electricity, pulse (blood pressure), it is the most responsive and be not subject to brain mind control and the physical signs of reaction people natural reaction to breathe in these three human bodies, and comprehensive psychology, modern medicine, electronics and computer technology design.
The work process of this psychological tester is as follows: pulse transducer is worn on measured's wrist, respiration pickup can place breast, abdominal part, the skin electric transducer is worn over respectively on measured's the finger, propose a series of problems of finishing in advance to the tested person then, require the measured to answer "Yes" or " not being ".If what answer is truth, produce a series of curves so, if what answer is lie, produce a series of different curves so, the physiological parameter that these curves are promptly gathered is respectively by pulse physiological parameter change-over circuit, physiology of respiration Parameters Transformation circuit, skin electric-physiology parameter change-over circuit, the A/D change-over circuit, and enter computer, the analysis software of detecting a lie in the computer writes down, analyzes, handles the data of gathering, and judges simultaneously whether the tested person lies.The data of test result use pictorial display on computer display, and can reproduce repeatedly by screen and printer.
" many reference amounts psychological test " that this psychological tester adopts has five effects: the one, get rid of not guilty; The 2nd, asserting crime suspect or insider; The 3rd, firm personnel in charge of the case's confidence is clearly investigated direction; The 4th, help investigator's analytic solution to burst to supply and evidence, the contradiction of confession and confession is distinguished false wittness; The 5th, the offender is formed powerful mental pressure, create conditions for breaking through case.For example: after a case took place, if security work is well-done, the plot of case, the situation of scene of a crime had only offender and scout to know; When some circumstances of crime layout problems of selection were tested, the True Crime molecule stimulated the variation that triggers physiological parameter owing to perfectly clear to circumstances of crime thereby must form psychology; And the innocent person knows nothing circumstances of crime, and the psycho-physical parameter does not just have significant change.Therefore, an innocent person is got rid of in test in this way, and asserting crime suspect or insider are very effective.
Carrying out many reference amounts psychological test application aims is science and the objectivity of utilizing " many reference amounts psychological test technology "; determine the investigation direction, can save human and material resources, financial resources, improve case handling efficiency; protection the country and people's safety fight crime effectively rapidly,.This psychological tester also can be the preceding psychologic status of athlete's test event, sums up and find out its best sports mental status; Also can be used for the key part, as the department of country's defendance, frontier defense, safety, secret department, the department that is engaged in economic loss investigation, licensed-type production, sale and storage control goods and materials, the department of security service is provided.
