The advanced standing long jump range finderis one of the series of products of The Intelligent IC Card Testing System for Physical Constitution Measurement.This device is a high technical product which is the combination of computer hardware and software.Under the study of the standing long jump range finder at home and abroad,an advanced standing long jump range finder that based on infrared LED and SCM (Single Chip Microprocessor) is developed,which takes advantages of the technology process in the fields such as electronic,computer,sensor and controlling. The standing long jump range finder discussed in this paper uses the PC to show the testing data.Different jumping-off points can be chosen for different people.It has stable capability and high precession.The measure error is less than one centimeter.Its practicality and well cushion and adhesion capability. The MCU AT89C51 is used as a core component in this standing long jump range finder.On the basis of the hardware design with the help of the software Altium Designer,this article decides to choose C language to program,and decides the gen
