智能立定跳远测试系统的设计与实现

In order to improve the standing long jump test precision, and meet the actual demand, this test system using infrared ranging principle and SOPC technology, with FPGA as the hardware carrier, Verilog HDL language and C language yesterday for the design and development of language, based on Nios II CPU chip system control nRF905 wireless transceiver module to complete the transfer test part and the control part of the point to point communications, the measured data to the host computer for processing and display and stored in the database. Testing process, the host computer through the data in the database to determine identity were measured, test control ends of the selected balkline, delimit the scope of FTIR test. The measured result error is + / - 1cm, but it is more intelligent and wireless.
