Intelligent Backlash Control System Based on Laser Scanning

Shengmin Zhang

Abstract


In the traditional round-trip sports training and competition, the coach or the referee observe the pinch table to
measure the athlete's performance, not only there is a large error, it will even miscarriage of justice, and the staff labor
intensity and low effi ciency. In order to solve these diffi culties, the system uses the simple and easy way by using
fingerprint identification module to collect athlete information, with low cost, wide application, easy to program
the STM32F103C8T6 and ATMEL89S51 as the core control measure a wide range of detection time is short, high
precision of the laser scanning athletes through the information to low power consumption, convenient and practical
nRF905 RF transceiver starting point and the return point of the communication to the LED display circuit count and
display, to automatically and accurately complete the athlete's performance test. This will reduce the workload of the
coach or the referee, but also improve the effi ciency and quality of work.
