How Electronics is involved in Cricket
Cricket is the game where 11 players for each team and 2 teams for each match will play. This game was originated in the British land in the late 16thcentury, from that day to today there are so many changes that occurred in this Gentlemen’s Game. Among all the Changes the Technological changes were something that everyone praised and following. We all know that electronics played a crucial role in developing the world drastically, every industry in this world took the help of electronics to change themselves into smarter ones. Cricket also adopted so many Electronic technologies into it for a better and fair game. Now let’s look at some of the technologies which changed the path of cricket dramatically.
This is a Revolutionary technology brought up in the field of cricket during the recent days, the usage of LED wickets rather than the ordinary wooden wickets was found to be more useful in determining the Batsmen Out and Not-Out Situation. In cricket, it is the rule that the batsmen should be given out only if the total bail was dislocated from its original position over the stump. So, this became a difficult task for the umpires to give decisions in some situations while using the conventional wickets. Then our LED wickets came into action which helped a lot for umpires to decide the Out or Not-Out condition. Here the LED in the bails and stumps will glow within the 1/1000th fraction of a second if the total bail was out from the stump.
Here some low voltage batteries are placed inside the stumps and bails along with a microprocessor and Reed sensors. A permanent magnet is placed on the top edge of the stump and the bails with reed sensors at the ends of bails will be placed over them. So, initially the reed switches will be closed when they are placed over the stumps, whenever the bails are dislocated totally from the stumps they will lose contact with the permanent magnet in the stumps and the reed switches will open, then this condition will make the microprocessor to turn on the LEDs inside the bails. There are also some LDRs placed over the stumps, so whenever the bails are removed from the stumps then this LDRs will receive light and this condition will make the microprocessor to make the LEDs in Stumps to glow.
So, these LED Wickets have made the umpires work easier and accurate to give the correct decisions.
One of the recent Technologies what we are observing in the cricket field is this Helmet Cams, these helmet cams were first used by batsmen in Big Bash League in 2012, this was introduced to give the audience who were watching the match through televisions a close and intense feel from the batsmen angle of vision, audience can feel like they were batting at the right moment through this vision. Later as this became a success, the umpires are also provided with these helmet cams to give the vision from another end of the pitch and also to make a chat with players over the field.
Initially so many felt that these helmet cams will cause discomfort to batsmen and may spoil their concentration during the match, but this whole system which combines the battery pack and camera doesn’t weigh more than 100 grams and that to the total weight will be distributed over the total helmet, so this doesn’t make any problem to the cricket fraternity yet it produced a classic experience for the audience.
In cricket so many times the batsmen left the crease with the wrong assumptions of umpires regarding their Out, this is because sometimes the batsmen may face a situation of LBW or keeper catch then the bowling team will raise an appeal that it is out. At that situation, the umpire should be accurate enough to say whether the ball has touched the pad or bat or at any other place to give his correct decision. But as we are all humans we may not get the correct picture of the actual situation, then there may raise some wrong decisions. So to avoid this one more advanced technology called Hot-Spot was introduced, with this technology the correct position where the ball touched can be clearly known.
In this Technology, two infrared cameras were used and they are placed on the either ends of the ground, these two cameras will record the total match at only one position that is near batsmen standing position. So what these two Infrared cameras will do means, they will detect position where the friction has occurred, the friction may occur when the bat touches the ball or pad or ground and even if ball touches the pad etc., So, whenever the appeal is made for out and if the umpire is in ambiguity then he asks the third umpire option and there they will check this hot-spot, if the friction is found between ball and pad or any other reasonable contact is found then that situation will be considered.
Many times we will see that whenever the batsmen hits a six then we can see that they will also indicate how much distance it travelled, and also we will see the future image of ball during LBW situations to indicate whether the batsmen is OUT or not, along with this we will see wagon wheels, pitch maps, rail cam etc., how we are getting all these information, who is there to measure the distance of six hit by the batsmen? There is no one other than our beautiful technology called Hawk-Eye.
This technology uses six high-speed vision processing cameras placed around the ground, these cameras will record the ball when it is delivered and a 3D future image of the ball is formed by combining the images recorded by the six cameras. This recording is also done in two parts one is from delivery point to pitch point and the second part is from pitch point to bounce point, by observing the way, speed, direction, swing and many more points the future image is calculated.
Similarly when the batsmen hit a six then these cameras will record the ball from the point of the hit to where it is landing along with the angle of hitting, the speed of hitting etc., to calculate the distance of ball traveled.
No Balls at Crease:
During bowling if the bowler crosses the crease then we will consider that ball as no ball, but how come the umpire knows every time whether the bowler is bowling accurately or not? There they use a technology where a buzzer will blow for the umpire indicating that bowler had crossed the crease, so the umpire can indicate that ball as no ball.
So, these are some electronic technologies that are being used in the game of Cricket, not only these there are so many beautiful technologies which will run every second when the match is going on, to make the result of the match much more accurate. So, this shows our Electronics is the show stealer where ever it enters.
Don’t forget to give your valuable suggestions.
