Considering requirement of timing cost and timing precision
a running test system based on combination of ZigBee and global positioning system( GPS) is designed to complete the task of college students’ long-distance running physical test. The ZigBee technique with high precision positioning characteristic is adopted to realize the judgment of end point arrival of running test and to realize the trajectory tracking of the tester by GPS technology which is convenient for wide range movement trajectory tracking. The hardware system of the ZigBee positioning module and the GPS trajectory tracking module is designed
and the ZigBee positioning algorithm and anti-collision algorithm are studied and shortcut cheating judgment program is designed using GPS module. By comparing the designed running test system with the manual timing method
the results show that the error of artificial timing has obvious randomness
the timing result is unstable
and the timing error of the designed running test system has good stability
and can basically reflect the real score of the tester.
