Background

The computer mouse competition scoring system is a scoring system for computer mouse maze-walking competition, and is used for accurately detecting and counting the scoring of competition conditions of each group of players. The system mainly comprises a starting point module for detecting whether the computer mouse leaves or not, an end point module for detecting whether the computer mouse arrives or not, a receiving module for receiving signals of the starting point and the end point, and scoring software for accurately detecting and processing the signals in real time.

When the computer mouse is put into the starting point of the maze, the starting point module starts to work, when the computer mouse leaves the starting point, the starting point signal is triggered due to the change of pressure, meanwhile, the signal is sent to the signal receiving module, and the signal receiving module carries out certain data conversion on the received signal and then sends the converted signal to the scoring software. When the computer mouse finally reaches the terminal, the pressure sensor of the terminal module detects the pressure change, the terminal signal is triggered, meanwhile, the signal is sent to the signal receiving module, and the signal receiving module performs certain data conversion on the received signal and then sends the converted signal to the scoring software. The final scoring software can obtain the search and run time of the mouse by calculating the detected start and end signals. According to the rules of competition, there is a time to hit the wall back to the starting point, during which time the time is not interrupted, but continues until the end point is reached again. And finally, the scoring software can display the competition result of the computer mouse on a large screen according to competition rules.

The prior art realizes the detection of a start point signal and an end point signal by the laser correlation of a start point module and an end point module.
