Research and optimization of sports injury medical system under the background of Internet of things

With the popularization of Internet of things (IoT) knowledge and the wide dissemination of technology, IoT technology medical and health industry has brought far‐reaching influence. This article studies the application of IoT technology in sports injury medical system, and expounds the application of telemedicine, mobile diagnosis, and user data management in medical system supported by IoT technology. First, the application layer, network layer, and perceptual layer structure of the IoT are used to plan the overall hierarchy of the sports injury medical system, and then the system is divided into three modules, which are the user physiological parameter acquisition module, the user physiological parameter processing module, and the motion damage diagnosis result module. Finally, the performance of the system is detected from packet loss rate and concurrency quantity, and it is concluded that the medical system of sports injury can meet the requirements of field diagnosis based on the background of IoT, and the user's satisfaction is found to be greatly improved by the results of user's investigation.
