Design And Implementation Of Psychological Test Systerm

Today's society is competitive, all types of people are under high pressure such as high-intensity work pressure, academic pressure and employment pressure. As the pressure increases, the ability of people can bear psychological pressure are receiving severe test.Foxconn jumping events, Doctoral student suicides etc are appear in the pages of major newspapers. Degree of mental health and emotional stability are getting more and more attentions. University is the place to develop high-quality personnel. High-quality personnel should be round development of talent.Current college students'psychological stress is increased significantly compare to the past few years.So as a growing group, college students'level of mental health should get more attention.Paper first analynis the key technology of psychological test system.On the base of these key technologies,Psychological test system was constructed.The system includes both hardware and software parts.Hardware includes:MCU control unit,data acquisition unit,data display unit,sound and light alam unit,serial communication unit,reset and clock unit,systerm power unit.Systerm's hardware part mainly use MCU technology for hardware design,use C51 language for programming and protel DXP2004 to draw systerm schmatic. Systerm hardware module is designed to collect tester's hand-shaking data to achive emotional stability of students.Systerm software module include:systerm log unit,systerm question test unit,systerm staff set unit,systerm database design unit,systerm data view unit,systerm data analysis unit.Systerm software module mainly programming by using VC6.0,while using SQL2000 for database design,and use control VSFlexGrid to design statements.The systerm software module use dual-scale measurement,in order to achieve quality status of a comprehensive psychological evaluation of students.At last, through this study and psychological measurement of students,this design of psychological test system is easy to operate, a friendly human-computer interaction, high reliability.Systerm uses MCU as the main control unit of hardware in order to reduce systerm design cost,and this systerm has high cost-effective.This design reduce impact of uncertainties which can be caused by single hardware or single software test, improve the objectivity and reliability of test results.
