Computer-aided physical training sports injury risk simulation based on embedded image system

In teamwork, injuries occur from time to time. The athlete's body is very important, so the rich experience of teamwork can reduce the injury to the athlete, which is a very important aspect of preventing the risk and mitigating the risk. There are several ways to reduce the risk factors of injury. One is to use positioning method, scientists have developed a 2.4 GHz frequency wireless receiving sensor system, referred to as WSN. This system can effectively monitor indoor and outdoor environment and identify and analyze buried active RF in advance. After several frequency tests, more effective performance is obtained, and the transmission power and signal intensity system are developed. It can generate high-frequency amplitudes, and the transmitted data can create independent labels to receive.
