"Liu Muyang, speed up, fast ......"Cao Rui, prepare for the rest ......Staring at the data on the tablet, Coach He kept shouting. The wrestling team of more than 20 people warmed up for training, and he was in good command by looking at the tablet in front of him.
This scene is a typical application scenario of group sports data monitoring in sports training. By monitoring the athlete's real-time heart rate, average heart rate, maximum and minimum heart rate, and heart rate risk warning in real time, coaches can get the best out of every training session while reducing exercise risks. This kind of long-term collection of training and competition data, such as sports time, distance, speed, heart rate, etc., can also help coaches more accurately understand the training status and performance level of each athlete, formulate personalized training plans and competition strategies, and improve athletes' training effectiveness and competition performance. In addition, this data can also be shared with athletes or related personnel, such as athletes' parents, coaches, nutritionists, team doctors, etc., to help them better understand the training and health of athletes, and provide better support and protection.
Group sports data monitoring has become an emerging application, the essence of which is the application of Bluetooth technology in the Internet of Things. Previously, Bluetooth Internet of Things technology was widely used in multi-dimensional data restoration, technical and tactical analysis and training of large-scale games, such as high-level events such as Champions League games and NBA games. Today, however, this application has expanded even further and is beginning to be extended to the daily training of athletes.
In China, the first scenarios to apply the Internet of Things technology to group sports data monitoring include campus physical education classes, sports training institutions, army training, sports events, etc. Beijing Osmanthus Network Technology, a leading company in Bluetooth Internet of Things, has developed a special Bluetooth Internet of Things solution for sports monitoring, which has achieved many successes.
So, how to deploy Bluetooth Internet of Things for this emerging group sports data monitoring?It can be illustrated in combination with a specific case: a training base is a professional military training institution, with a 400-meter standard playground and a 200*200-meter training field, providing various training programs for thousands of soldiers every year. The agency hopes to collect real-time data on the physiological signs and movements of soldiers in training, detect health and sports risks and give timely warnings, prevent the occurrence of training injuries, and at the same time grasp the training situation and achievements of soldiers, so as to improve the effectiveness and quality of training.
Each x1000 Bluetooth gateway can connect 22 Bluetooth bracelets in both directions at the same time in the training ground, providing reliable and seamless connection, and conveniently connecting the bracelet data, including heart rate, blood pressure, blood oxygen, body temperature and other physiological indicators, as well as steps, calories and other sports data, through Bluetooth and the gateway connection, the data will be real-time and safe back to the background platform. Managers can easily remotely monitor and manage hundreds or thousands of Bluetooth bracelets from one system platform.
In this case, the most noteworthy is the Bluetooth gateway, the osmanthus network Bluetooth gateway X1000 is a high-performance outdoor dedicated Bluetooth gateway, each capable of covering a radius of 300 meters. In addition to real-time connection, it can also support batch collection of 2,000 people at the same time in the form of scanning to ensure that the data of all participants is not lost. It supports Bluetooth 4 Low Energy1 standard, support edge computing, waterproof, dustproof and lightning protection, can work at -40 to +65 degrees Celsius.
In addition, the Osmanthus Internet of Things Controller (AC) is used with the gateway to be responsible for data ** and security encryption, and transmits the data collected by the Bluetooth gateway to the background platform through the customer's intranet. AC also has a roaming function, the bracelet can move freely within the coverage of multiple gateways, the device is constantly connected, and data is not lost.
Through the above cases, it is not difficult to find that group sports monitoring has a broad application prospect. So, what is the difference between such group exercise data monitoring and individual exercise data monitoring?
To put it simply, it is the difference between networking and stand-alone.
Personal sports data monitoring is a "stand-alone", simply put, "self-management", through the use of smart bracelets, smart watches and other wearable devices to monitor the exercise process, the monitored data including heart rate, steps, calories burned, etc. can be presented on the mobile phone APP for the reference of exercisers, to help individuals better understand their own exercise situation, in order to achieve the purpose of health management and exercise effect improvement.
Group sports data monitoring is "networked", which can be understood simply to achieve "one coach in charge of many people". By arranging a Bluetooth gateway in a training field, playground or gymnasium, the Bluetooth signal can cover everyone's entire workout. The monitored athletes use Bluetooth bracelets, Bluetooth armbands or Bluetooth skipping ropes, and upload the sports data collected by these devices to the management platform through the Bluetooth gateway.
Judging from the feedback from all parties so far, the comprehensive feedback of group sports data monitoring is positive:
· Physical Education Teacher: Don't worry about going to class anymore
According to the survey, more than 80% of PE teachers believe that the current work pressure is "very high" or "relatively high", on the one hand, because of the heavy workload, and on the other hand, because of the fear of class safety.
Just by staring at it, you can't find a lot of problems. A physical education teacher bluntly said that nowadays students are generally in poor physical condition and are prone to injury, once a student has an accident, parents will find teachers, and even lawsuits, and the school will severely punish physical education teachers.
In physical education, the most common and dangerous are sudden arrhythmias, heat stress, heart disease, etc., real-time monitoring of students' heart rate and other vital signs data can detect students' physical abnormalities in time. In the event of abnormal data, teachers can immediately take appropriate measures, such as reducing the intensity of exercise or arranging medical assistance, to protect the health of students. This helps to prevent accidents during sports activities and provides a strong guarantee for the healthy growth of students.
· Athletic training institutions: effectively improve the effect of exercise on the basis of safety
Now, all kinds of physical fitness, basketball training halls, dance training halls, etc. have sprung up, and correspondingly, the training effect is also "rolling" greatly. Physical fitness, basketball training halls, dance training halls and other sports training institutions, generally adopt small class teaching, no matter how small the class must have 5-10 children, just rely on the coach to stare with his eyes, remember carefully, still can not achieve the goal of safety and effect. The introduction of group sports monitoring not only ensures sports safety, improves training effectiveness, but also enhances the competitiveness of sports training institutions.
In short, the development of smart wearable device technology and the application of Bluetooth Internet of Things and big data health management have provided stronger support for smart sports and science and technology. Looking to the future, with the advancement of technology and the increasing importance of people's health, everyone can get "higher, faster, stronger, healthier, more efficient" workout results like never before.
