Design of Referee System for Competition Based on Wireless Sensors Networks

In the current scoring process of robot competition in primary and secondary schools, most of them use manual referees, resulting in insufficient fairness in the competition, waste of human and material resources and other problems. In this paper, sensor technology is used to detect the running position information and related parameters of the competition robot, LoRa wireless communication technology is used to realize the signal transmission between the signal acquisition equipment and the gateway, and the upper computer software is designed to display the score and complete the record, which makes up for the shortcomings of manual scoring in the competition. The experimental results show that the system has high stability, fast scoring speed, and can complete the automatic timing and scoring of robot competitions, automatically feedback the completion of robot tasks and judge the scores according to the completion of tasks.
