ABSTRACT
Project Title: Research, design, and implementation of equipment to monitor players
on the football pitch
This project aims to develop a tracking and support device for football players during training and matches, using the ESP32 module and integrating sensors such as DWB1000 (position tracking), AD8232 (heart rate monitoring), and MPU6250 (acceleration and velocity measurement), along with designing a PCB circuit to optimize device size.
The device collects data from sensors and then utilizes algorithms to compute player position, heart rate, and velocity. The ESP32 microcontroller serves as the central processing unit, ensuring rapid data processing and collection from sensors. Additionally, a Low Pass filter is employed to reduce sensor noise.
The player-worn device can communicate via TCP and ESP32 wifi connection. Subsequently, the collected data is pushed to a web server, such as NodeRed, which provides detailed information about player position, heart rate, motion, formation distances, and player reminders through real-time device vibrations during and after training sessions and matches.
Ultimately, players and coaches can utilize the statistical website to track player performance and health, facilitating training adjustments for better results. The next development goal is to optimize device size and weight to enhance usability for both players and coaches.

CHAPTER 1: INTRODUCTION 1.1. The urgency of the topic
Thesis research on a device used for football players to track and evaluate player performance. EPTS (Electronic Performance and Tracking System) is one of the tools that FIFA has implemented to measure player distance and track the ball. The International Football Association Board (IFAB) decided to allow players to use wearable technology in official football matches in March 2015.
In recent years, the popularity of using wearable player tracking devices has been on the rise. This is a lucrative market for companies and businesses to invest in and develop such devices to generate revenue. Countries that are pioneers in this field include companies from Germany, England, Austria, etc. They have successfully developed and promoted their products, the most visible and familiar being the Premier League, where all players from each club wear a vest-mounted device under their main shirt when they take the field. In addition to the usual playing accessories such as: shirts, pants, specialized shoes, socks, protective pads, etc., there is now a vest with a device attached. Some famous brands like Captapult, Playertex, etc., they not only develop in the king of sports but also spread to other sports such as basketball, rugby, volleyball, etc.
Figure 1.1: Electronic Performance & Tracking Systems
Although it is so famous, it is still not well known about this technology in Vietnam. Recently, in the 2022 World Cup qualifying campaign of the Vietnam national football team, we began to see the appearance of Catapult monitoring vests on the bodies of players such as Tien Linh, Cong Phuong, Quang Hai, etc. This shows how the impact of technology in football is spreading.

Through the specific evidence as above, we see the need for a device to track the basic parameters of the trainer when training or competing to track the basic parameters of the body such as the number of kilometers of movement, training speed, and also the heart rate of the trainer. From these parameters, we can adjust the training regimen for better fitness. Such a device is essential during the training period to track the distance and speed of movement of the players on the field as well as their heart rate. Then, this information is transmitted to another monitoring device outside the field to be recorded. This allows for a more accurate grasp of the health status of the players and to develop more appropriate training and competition plans for each position on the field. Realizing the need for a device that can fulfill the above tasks, the group has researched the topic: " Research, design, and implementation of equipment to monitor players on the football pitch".
1.2. Scientific and practical significance of the topic:
The urgency of the research, design, and deployment of the player tracking device on the football field lies in the wide range of benefits and applications it brings to the field of sports and training. Here are some specific aspects:
- Optimized Training Performance: The device helps to optimize training performance by providing accurate information about the player's position, heart rate, and movement. This helps coaches to adjust training plans to meet the specific needs and abilities of each player.
- Personal Health Management: Monitoring heart rate and movement measures helps to assess the player's individual health. This not only helps to prevent injuries but also creates a suitable training regimen for each individual.
- Optimized Formation and Tactics: Data on player position on the field helps coaches determine the best tactics and formation for each game situation. This increases the team's chances of winning.
- Real-time decision-making: The data is updated continuously, supporting immediate decisions in real-time. This is important in situations that require flexibility and quick response from coaches and players.
- Enhancing the Personal Experience: By providing detailed information about the player's activity, the topic helps to create a positive and motivating experience for the player. Tracking individual progress can increase commitment and passion in training.
- Contribution to Technology Research: The research not only addresses challenges in the field of sports but also contributes to the development of sports tracking and evaluation technology. This could open the door to new advances in this field.

In conclusion, the urgency of this topic lies not only in the specific improvement of the performance of players and teams, but also in the aspect of contributing to the development and modernization of the field of sports and health tracking technology
1.3. Research Target:
In the project, we set a number of important goals to ensure success and high efficiency:
- Researching the commercial products currently used by major football teams worldwide.
- Designing a model of the product with basic functionalities compared to the actual product with high stability.
- Analyzing and processing data collected from sensors.
- Designing a display interface and data statistics.
- Adding a feature to remind players on the field during training.

CHAPTER 1: INTRODUCTION 1.1. The urgency of the topic
Thesis research on a device used for football players to track and evaluate player performance. EPTS (Electronic Performance and Tracking System) is one of the tools that FIFA has implemented to measure player distance and track the ball. The International Football Association Board (IFAB) decided to allow players to use wearable technology in official football matches in March 2015.
In recent years, the popularity of using wearable player tracking devices has been on the rise. This is a lucrative market for companies and businesses to invest in and develop such devices to generate revenue. Countries that are pioneers in this field include companies from Germany, England, Austria, etc. They have successfully developed and promoted their products, the most visible and familiar being the Premier League, where all players from each club wear a vest-mounted device under their main shirt when they take the field. In addition to the usual playing accessories such as: shirts, pants, specialized shoes, socks, protective pads, etc., there is now a vest with a device attached. Some famous brands like Captapult, Playertex, etc., they not only develop in the king of sports but also spread to other sports such as basketball, rugby, volleyball, etc.

Although it is so famous, it is still not well known about this technology in Vietnam. Recently, in the 2022 World Cup qualifying campaign of the Vietnam national football team, we began to see the appearance of Catapult monitoring vests on the bodies of players such as Tien Linh, Cong Phuong, Quang Hai, etc. This shows how the impact of technology in football is spreading.

Through the specific evidence as above, we see the need for a device to track the basic parameters of the trainer when training or competing to track the basic parameters of the body such as the number of kilometers of movement, training speed, and also the heart rate of the trainer. From these parameters, we can adjust the training regimen for better fitness. Such a device is essential during the training period to track the distance and speed of movement of the players on the field as well as their heart rate. Then, this information is transmitted to another monitoring device outside the field to be recorded. This allows for a more accurate grasp of the health status of the players and to develop more appropriate training and competition plans for each position on the field. Realizing the need for a device that can fulfill the above tasks, the group has researched the topic: " Research, design, and implementation of equipment to monitor players on the football pitch".
1.2. Scientific and practical significance of the topic:
The urgency of the research, design, and deployment of the player tracking device on the football field lies in the wide range of benefits and applications it brings to the field of sports and training. Here are some specific aspects:
- Optimized Training Performance: The device helps to optimize training performance by providing accurate information about the player's position, heart rate, and movement. This helps coaches to adjust training plans to meet the specific needs and abilities of each player.
- Personal Health Management: Monitoring heart rate and movement measures helps to assess the player's individual health. This not only helps to prevent injuries but also creates a suitable training regimen for each individual.
- Optimized Formation and Tactics: Data on player position on the field helps coaches determine the best tactics and formation for each game situation. This increases the team's chances of winning.
- Real-time decision-making: The data is updated continuously, supporting immediate decisions in real-time. This is important in situations that require flexibility and quick response from coaches and players.
- Enhancing the Personal Experience: By providing detailed information about the player's activity, the topic helps to create a positive and motivating experience for the player. Tracking individual progress can increase commitment and passion in training.
- Contribution to Technology Research: The research not only addresses challenges in the field of sports but also contributes to the development of sports tracking and evaluation technology. This could open the door to new advances in this field.
