Electronic Scoring Hockey Goal
Introduction Group Information Important Documents Links
In hockey, there are situations in which goals are counted, but with great uncertainty. A goal is scored when the entire
hockey puck crosses over the line which directly in front of the lower goal frame. However, instances such as player
pileups and goal interference happen frequently, and the referees have to resort to using vision to determine a goal being scored.
Player pileups happen quite frequently, and oftentimes, referees have to resort to instant replay cameras to determine whether a goal has been scored or not.
Not only does this take time, but it also takes extra effort from additional personnel who operate these cameras.
The game slows down, causing longer delays, and the flow of the game can be lost.
What the group proposed is an electronic scoring goal system that will be able to detect whether a goal has been properly
scored or not. The system will include an apparatus known as a Gunn oscillator, which sends out radio signals.
Copper wire will be placed inside the hockey puck, so that the signals sent out by the Gunn transceiver will receive
reflected signals from the hockey puck. When the hockey puck is within a certain range of the Gunn transceiver, it
will trigger a circuit which will turn a series of LEDs on, triggering a proper goal being scored.
The issues which are addressed in this system include object interference, incorrect goals being scored,
as well as being able to eliminate outside sources from triggering the system to inaccurately imply a goal being scored.
