Title: CAMPUS GUN-JUMP PREVENTION SYSTEM
Abstract:
Provided is a campus gun-jump prevention system, comprising a starting block (1) and a starting gun (2); the starting block (1) is used for providing a pressure sensor (10) at the contact interface of the sole of the shoe of an athlete; also comprised are a sound sensing module (3) and a microprocessor (4); the sound sensing module (3) is used for sensing the sound of the starting gun (2), then sending a signal to the microprocessor (4); the pressure sensor (10) is used for detecting pressure and sending data to the microprocessor (4); the microprocessor (4) is used for comparing the time at which the signal sent by the sound sensing module (3) is received and the time at which the pressure sensor (10) detects a maximum pressure; when the starting gun (2) emits sound, the sound sensing module (3) senses it and sends a signal to the microprocessor (4); a student starting to run causes the pressure sensor (10) on the starting block (1) to sense that the pressure has reached the maximum value; the microprocessor (4) receives and then compares with the time at which the signal is sent by the sound sensing module (3), thereby simply determining whether the student has jumped the gun and guaranteeing the fairness of the race; the overall structure is simple and costs are low.
