Electronic Technology of the World Cup in Brazil
The pace of the 2014 World Cup in Brazil is getting closer and closer to us. This four-year football event, in addition to being able to see the sweaty figures of the players on the pitch, we can also see many of the latest implanted cutting-edge technologies. For this World Cup, high technology has undoubtedly become one of the biggest highlights.
This article refers to the address: http://
Door line technology, football design concept, 4K technology, human wall spray technology, high-tech chip shoes and strict comprehensive security technology have all become the highlights of this year's World Cup in Brazil. While fans are enjoying the intense competition, We will also be amazed at the high level of technology investment. In this issue, we will take a look at the cutting-edge technologies in the World Cup in Brazil.
Door line technology 360 degrees without dead ends
I believe that the fans still remember that in the last World Cup, the "Lampard Gate Line" case, because of the technical aspect of the goal line monitoring, there is a dead angle, resulting in a goal, the players of both sides on the referee's penalty is very controversial, this It also aroused the dissatisfaction of many fans and athletes.
Indeed, athletes have to sharpen their swords in four years, in order to be able to take the lead in the World Cup. If some technical means are not mature, which leads to the scoring of goals, it is true for the protagonist of "false and wrong". A bit too unfair.
In order to avoid the recurrence of the "door line", the Brazil World Cup Organizing Committee will use the door line technology for the first time in this World Cup in Brazil at the request of FIFA. The so-called door line technology, that is, in each game field. Installed 14 high-speed cameras for capturing the football's trajectory and running distance from the air. At the same time, about 7 monitoring devices will be installed around each goal, and the goal will be enclosed to ensure 360-degree dead angle. .
The biggest advantage of this kind of door line technology is that it works through a lot of monitoring equipment, and then the background equipment analyzes the data to ensure that the system can give the exact conclusion after the ball passes the goal line for one to two seconds, and the conclusion Immediately, it will be sent to the watch of the on-site referee by wireless signal, effectively avoiding the recurrence of the “door line fileâ€. Netizens can also pay more attention to this World Cup. Watching live broadcasts with 4K is more enjoyable
4K technology is a hot technology newly developed in recent years, and the attention of ordinary users is getting higher and higher. Just last year, Sony, the leader in 4K field, announced that it has cooperated with FIFA to conduct the World Cup. 4K live broadcast, in this World Cup, the organizing committee will determine through the 4K technology to broadcast three heavyweight competitions including the championship and runner-up finals.
FIFA also decided to negotiate and cooperate with the plazas and shopping malls of some major cities during the World Cup to establish a number of 4K big screens for live broadcast of the World Cup. This will not only allow the fans to feel the World Cup. Come to the football carnival, but also be able to experience the new experience of 4K technology.
Wall spray technology
At the end of last year, FIFA President Blatter made it clear at the press conference that during the World Cup in Brazil, the spray technology that limits the distance between the free kick and the wall will be used for the first time, which can effectively prevent players from sending The occurrence of a transboundary phenomenon in a free kick.
This kind of wall spray technology will strictly control the distance between the wall and the ball to a distance of 9.15 meters. After the site referee estimates the distance, it will use a special material. The foam spray is used to delineate the "warning line", which can effectively avoid the player's cross-border phenomenon.
At the same time, the spray can help the referee to be more accurate in determining the position of the free kick, and the trace of the spray can disappear completely within one minute without any influence or interference on the lawn marking on the spot.
The game ball is more said
Let’s talk about the ball "Samba Glory" in this year's World Cup in Brazil. As a provider of balls for the World Cup for many years, Adidas continues to provide the ball for the World Cup. This year's "Samba Glory" has strictly carried out a number of wind resistance tests in the design, and found more than Messi. The top players did the actual field test, only one purpose, in order to avoid the opinion of many players in the World Cup in South Africa.
In the last World Cup in South Africa, many players responded to the game at the time and felt like playing beach football. For players who rely on the free kick to "play the world", this irregular ball is undoubtedly a big one. problem.
In order to avoid similar problems in the use of the ball in this World Cup, Adidas specially invited technicians from many different countries to conduct a comprehensive test on "Samba Glory". The test results show that the ball for this World Cup is due to The use of six propeller shape block technology, which makes the wind resistance greatly reduced, the football stability is even higher than the traditional black and white leather appearance of the football. I believe that there will be more "world waves" in this World Cup. Chip shoes make the data more accurate
Today is an era of data explosion. The analysis technology for big data is quite mature. This is not surprising in the sports world. During this World Cup, the most widely used application for big data analysis should be the shoes at the foot of the players. It is.
The shoes worn by many players in this World Cup are a football shoes with chips designed by Adidas in 2011. This football shoe named adizero f50 uses the miCoach function of Adidas. The shoes can capture the athletes on the court. Any set of actions on the top, and large-capacity storage of data such as the physical conditions generated by these actions, can be stored for up to 7 hours.
After the game, the player can upload the chip in the sneaker to the personal device to export the individual game data of the game for comparison and analysis, thus helping the player and the coach to understand each player more accurately. In this case, any adjustments are made to the training and the next game in time.
Strict security inspection technology guarantees safety
No matter which country, any large-scale sports event will attach great importance to the security of the competition. For this year's World Cup in Brazil, no. In the security inspection, 12 World Cup venues have installed security equipment from China. The penetration of the item will be stronger, the scanned image will be sharper, and the dangerous item will be easily identified.
It is worth mentioning that the security equipment outside these venues, in addition to on-site security inspections, can also perform long-term storage and playback functions of security data and images in real time while security checks, thus making the World Cup in Brazil more secure.
