This year's Rio Olympic Games has already come to an end. The Chinese Army has exerted all its strengths on major projects. Too many wonderful moments are overwhelming. I believe that this session of the Olympic Games must have been: the expression package and Duan Zi Qi Fei, a total of glorious honors, fresh meat attack, shining South American coast, flying flowers, the name of the history of the five rings.
As the highest-standard competitive game in the world today, the Olympic Games brings together top athletes in all fields of the world. Every match is a breakthrough in human physical fitness and explosive power. The difference between champions and runner-ups is often in the slightest. A large number of sensors are used for the determination of the speed and for the collection of training data.
In this regard, TE Connectivity, a global connector and sensor supplier, is applying its sensor technology in a new way to help people track, measure, and analyze data in sports or leisure activities. This article will reveal several applications for the Olympic Games. On the black technology.
Swim
Over the past few days, the prehistoric teenage girl Fu Yuanhui had amused the people all over the country with an interview video of (dou) love (bi). The reporter told Fu Yuanhui that you had traveled 58 seconds 76. Only Biya Jun slowed for 0.01 seconds. Fu Yuanhui said that it may be my hand is too short.
What is the concept of 0.01 seconds? In such a short time, how can the referee accurately determine? What is the relationship between the short hand and the time spent?
Swimming masters are tricky, winning is often between the electro-optic flint, for just 0.01 seconds gap, the referee is difficult to observe with the naked eye. Therefore, swimming games rely on automatic timing systems to monitor athletes' performance and performance. The system includes a launcher, touchpad, timer, electronic display, video system and more.
In the departure phase, the originator's starting gun information is transmitted to all starting stations and ensures that all players hear both the password and the departure signal. When the athlete hears the starting signal and jumps into the water, the pressure sensor on the pressure board on the starting platform can record the departure time of the athlete in real time to monitor whether he has jumped foul.
On the wall at the end of both lanes, there is a touch panel. When the athlete touches it with a finger, the sensor on the touch panel will be recorded to prove the track and time of the athlete.
Therefore, in swimming competitions, highly sensitive sensors are needed. The athlete can record the data by touching it lightly, but it does not generate erroneous data due to the fluctuation of the water in the pool. At the same time, the sensor is not at risk of electric shock for the purpose of protecting the athlete.
As for the short-sightedness of our pioneering girls, it's right. After all, a sensitive sensor needs your little short hand to touch the touchpad to sense it, right?
Athletics
Another large gold medal track and field athletes will soon have a full battle.
In the past, track and field athletes achieved results relying on their perseverance and their own hard work. Today, track and field sports have begun to introduce a large number of high-tech training methods.
The men’s 100m surfer, who ran for 9 seconds 99 at the Beijing World Championship last year, was the first Asian athlete to run for 10 seconds. Unlike many traditional trainings in the past, Su Bingtian’s training also benefited from high-tech applications. 
Through the real-time monitoring of Su Bingtian's running, the coach found that Su Bingtian's starting run turned into a flat run. However, the medium-range rhythm was not good enough to exert speed and strength and became a bottleneck for his skills and performance. In this regard, the coach asked Su Bingtian to change the position of the starting foot on the starting block and change from 47 steps to 48 steps.
It is such a seemingly simple change that Su Bingtian’s right foot increases the strength of the starting ground as a kick leg, strengthens the starting advantage, and adds to the two-run route between 30m to 50m and 50m to 70m. Focus on improving, Su Bingtian won this gamble.
How does this real-time monitoring come from? This depends on the "combat suit" on the athlete.
Compared to coach observation, video playback, and athletes' own feelings, the micro-wearable device in the sports vest can more accurately and comprehensively grasp the biometric data, behavior habits, and exercise data of the athlete's running.
The accelerometer sensor in the wearable device can monitor the pace and speed of each step of the athlete's running in real time; the breathing sensor tracks respiratory frequency and vital capacity to prevent overexposure; and the heart rate sensor measures heart rate changes to prevent stress and fatigue.
With these large amounts of data and detailed information, athletes and coaches can pinpoint exactly what needs to be improved – whether it is necessary to increase training for lung capacity, whether to speed up at the start, and whether to adjust the position of the hands when running.
With these high-tech technologies, sensors, and wearable devices, athletes' training methods are becoming more scientific and effective.
Similarly, pole vaulters and high jumpers can improve performance by monitoring the height of various parts of the body by passing an altimeter sensor on the head, hands, feet, and hips. Monitoring the height and movement of the limbs and accurately grasping the timing of each movement helps to create a perfect movement for all parts of the body.
Fencing
Speaking of heroic heroes, he could not help but mention another knight's movement - fencing. At this year's Rio Olympics, young and handsome fencing players have become hot topics in social media. As the traditional strengths of the Chinese Fencing Team, the group projects that are about to take place are very exciting.
The new generation of "Three Musketeers" led by thunder is also reminiscent of the Chinese men's foil swordsmen of the year - Wang Haibin, Ye Chong and Dong Zhaozhi.
In the men's foiled team final of the 2000 Sydney Olympics, Wang Haibin took the lead and stabbed each other. The light was on and the referee awarded the score to the French team. At the Athens Olympics in 2004, the referee made many misjudgments. Both sides on the spot When the lights were on at the same time, almost all the scores were awarded to each other, which caused the fencing team to miss the gold medal again. The Three Musketeers did not compete for the Olympic Games because of these misjudgments. It can be a regret for a lifetime.
How can we prevent miscarriage from happening?
In fact, "seeing is believing" is far inferior to "using data to speak." The referee can only be impartial and then "eyes like a torch", and there may still be visual dead ends. With more accurate technical means, it is possible to ensure that the game records are true and reliable.
This can start with the fencing athlete's costume and sword.
The athlete’s clothes are clothed with a conductive metal sensor to form a circuit to transmit electrical signals; and there is a spring on the tip of the sword. Once the other’s clothes are hit, the pressure sensor on the tip of the sword can detect the impact. The position and intensity of the shock, if the detected impact strength reaches the specified value, the circuit will be switched on so that the athlete's helmet and the lights in the venue will light up.
Through the sensor, the impact strength of the fencing can be monitored. How about the time? Think about it, if you add a sensor to monitor the impact time, just like swimming as before, can it reduce the occurrence of misjudgment?
Sensors are helping us to become faster, stronger and healthier. Whether it is an athlete or an ordinary person who pays attention to health, more and more wearable fitness accessories such as wristbands, watches, headbands, necklaces, etc. are built with micro-sensors to monitor physiological parameters of the body or physical parameters of the surrounding environment.
Sensors are also increasingly being used in sports equipment such as: tennis rackets, golf balls/clubs, snowboards, rugby/hockey helmets, vests/clothing, track shoes/running shoes, and horse racing saddles, racing cars and regattas.
