According to the official Weibo of the FIFA World Cup, on the field, Messi scored with a point shot, followed by three shots from Argentina. A goal was disallowed, and Saudi Arabia scored two goals in the second half, eventually reversing Argentina.
According to Sina Sports, this is the first win for an Asian team, while Argentina is After 1990, he lost again in his World Cup debut after 32 years.
While the comment area was boiling, some netizens noticed: Messi’s feet This football has a chip installed.

Argentina’s defeat is not the first One surprise. Yesterday, just 3 minutes into the opening game between host Qatar and Ecuador, the first controversial penalty appeared. An offside formed by one foot, technology finally proved the accuracy of the penalty.
A high-tech football loaded with high-speed chips gradually shifts the penalty authority on the field from the pitch to the front of the screen. The black technology in the World Cup, the local tyrants in the Middle East not only smashed an oasis in the desert, but also changed the ecology of the World Cup. When people lament that “the end of football is actually a chip”, in fact, every World Cup is blessed with innovative technology and modern technology. Various sensors, artificial intelligence, advanced technology and other “black technologies” make the game more shocking and interesting. .
What kind of advanced technology is “full of technology” in this year’s World Cup in Qatar? Let’s take a look together.
1. Built-in central “chip” to accurately record football data

Qatar World Cup will introduce “Dream Journey” (Al Rihla, Arabic means “journey” ), which is a new revolutionary football.

< p data-track="29">Dream Chaser is understood to be equipped with an Adidas suspension system that includes an inertial measurement unit (IMU) sensor that detects severe offsideevent. The sensor is located in the center of the ball and can send the data of the ball to the video operation room 500 times per second, so that the kicking point can be detected very accurately, and high-precision ball movement data can be collected and sent to the referee.

Zhao Ying, secretary-general of Shenzhen Integrated Circuit Industry Association, said that the technology used in this built-in sensor is MEMS (Micro Electro Mechanical System). “Based on MEMS technology, various accelerometers, optical sensors, pressure sensors, gyroscopes, humidity sensors, and gas sensors can be made.”
Similar technology is actually used in basketball, tennis and other sports It should have been used in China early, but this is the first time it has been used in football. The technical principle of CTR-CORE is similar to a gyroscope chip, which can fully record the initial speed, running speed, movement angle and other data of the football. In particular, football is an extremely competitive sport. How to make the chip have better stability and the accuracy of recording motion trajectory is not a small technical difficulty.
2. Semi-automatic offside technology: smarter “referee”
Semi-automatic offside detection technology (SAOT) has undergone certain practical tests in football. In the Arabian game held in Qatar last year, The technology was put into use and was later introduced in the UEFA Super Cup and UEFA Champions League. However, this technology has been officially applied to the World Cup, which is the first time in football history.

< p data-track="44">As an extension of video assistant referee technology (VAR), SAOT can not only reduce controversial offside judgments, but also shorten judgment time. 12 special cameras will be set up on the top of each stadium, sending data at a frequency of 50 times per second, collecting data of up to 29 data points, and generating 3D animation images to judge in real time whether players are involved in offside.
Compared with the previous method of video playback + manual assistance to judge offside, the SAOT system can undoubtedly achieve without manual assistance. To accurately determine whether the player is offside or not.
3. Stadium cooling technology, smart and comfortable
The Qatar World Cup arena is also more comfortable and intelligent. Although it is November now, the temperature in Qatar is still likely to reach around 25-30°C. In order to provide athletes and fans with a more comfortable competition and watching environment, the arena adopts advanced cooling technology and cooperates with the retractable arena roof to keep the temperature at 18-24°C.
There will be an energy center near the stadium through which cold water will be passed Ducting to the stadium. Ventilation vents are installed around the football pitch and below the spectator seats. During the game, cold air will be continuously pushed from the vents to the pitch and spectator area.
This system mainly uses the thermal energy converted from solar energy for cooling, and the cold air is circulated through the pipes to the entire stadium. This technology is used for the first time. Among the 8 stadiums in this World Cup, 7 have adopted advanced cooling technology to keep the stadium cool.
4. Sustainable stadium
As one of the venues for the 2022 World Cup, the 974 Stadium may “disappear” after the World Cup.< /span>
This is because the 974 stadium is the first completely disassembled stadium in the history of the World Cup. This stadium is built using containers and modular steel frames, of which 974 means that the stadium uses 974 recyclable shipping containers.
5. Strong technical and humanistic care, allowing everyone to experience the assistive technology of the event
The Qatar World Cup also has a strong humanistic care, using assistive technologies with excellent experience such as Bonocle, Feelix Palm, and sensory viewing rooms.
Bonocle: The world’s first braille entertainment platform that provides the visually impaired with all assistive technologies to access digital content, enabling They can also enjoy the game like everyone else.
Feelix Palm Technology: uses electrical impulses to deliver Braille-like information to the visually impaired via a tactile palm communicator without limiting their Physical movement or hearing.
Sensory Viewing Room: Can provide a safe and calm space for young people with autism or sensory processing issues Enjoy the fun of the game in an environment.
6. Wearable devices for medical assistance

This cool black vest, Is a wearable electronic device, these jerseys work via bluetooth and are able to send detected data to a base station for real-time monitoring of the wearer’s vital signs. The original intention of its design is to develop a series of wearable electronic devices to avoid medical emergencies.
7. Convenient digital facilities and APP
Tournament organizers want to ensure spectators are always in communication. All venues are surrounded by an ElPalm pavilion with solar panel-powered wind turbines that not only provide shade for fans, but also provide them with USB charging stations and WiFi access.
A series of sensors around Doha will provide real-time information to help fans get to and from the stadium. The traffic information of taxis, parking lots, subway systems, and venue entrances and exits will be pushed instantly through the customized App, which can also realize easy navigation inside the venue.
In addition to fans, athletes participating in the World Cup will also be able to gain insight into their performance on the field through an app (FIFA Player App). After each game, each player can log in to the App to view their performance and other data on the field.
