Charging Efficiency

With the development of the times and the progress of science and technology, people continue to explore new possibilities; the leap from wired to wireless is one of them, breaking the limitations. Similar to wireless mice and wireless microphones, this paper aims to study an Internet of Things-based smart wireless charger that, by using mathematical analysis and wireless charging technology, requires experiments to include wireless charging stations, associated chip areas, and home gateways that are used in combination with them. In the experiment, the control circuit, transmit circuit, and reception circuit of wireless charger are studied, and the wireless charging system is analyzed and calculated in detail, and a wireless charger is designed. Electromagnetic field sensing, radio wave transmission, and resonance methods are applied to achieve the shortest charging time and the best quality in order to prevent the charger from heating and burning during charging. Experimental data show that this Internet of Things-based smart wireless charger can fully replace wired chargers for 99% of small appliances; the charging efficiency of large electrical appliances such as desktop computer is also 1.4 to 1.6 times increased. Experimental data show that this Internet of Things-based smart wireless charger can efficiently and conveniently charge electrical appliances; however it is relatively expensive; the required technology is relatively complex but can make charging more efficient. It can be seen that wireless charging has a major breakthrough in the concept of future charging.

Internet of Things is a special concept of realizing intelligent sense, location, tracking, monitoring and management. It has been formally listed as one of five new large strategic industries. But because the construction of Internet of Things is still stay initial stage of research and exploration. Compared with the current internet, the Internet of Things has not only specific framework system, but also its concept, scope, technology system and standard are not clear. From above, based on grasping the definition, characteristics of the times and current situation of the Internet of Things and combining the connotation of educational resource sharing, this paper just talk over the application of the Internet of Things in education and study how to realize educational resource sharing better with the environment of the Internet of Things.

In recent years, College PE has received more and more attention. Traditional PE and teaching cannot meet the demand of students in today’s society and cannot attract students’ interest in sports. Under the current situation that the country actively promotes information science education, there is an urgent need to innovate PE teaching methods. VRT is very important to support college PE. In order to improve the quality of university PE and increase students’ interest in sports, this article uses the Internet of Things as a research background and 5G technology as a research topic. It provides technical support for the Internet of Things and research sports colleges on the Internet of Things. This study builds a virtual sports teaching environmental education through VRT. Experimental data were collected by sensors and other types of infrastructure. The experiment counted the number of sports safety incidents that occurred before and after the application of VRT in five universities of A, B, C, D, and E, collected and analyzed the teaching data of PE teachers in five universities, and studied the changes in student learning and interest in sports. These experimental data are used to analyze the impact of the application of VRT in PE on sports safety, PE teachers, and students. The final result shows that, after applying VRT in PE, the five schools have reduced the number of safety incidents in sports by more than 65%. VRT has the greatest impact on the teaching philosophy of PE teachers and the least impact on teachers’ teaching management. After the application of VRT, the number of students who independently engage in PE and sports has increased by more than 20%, and the students’ interest in sports learning and sports has increased. Finally, the application of VRT in the PE of the five schools accounted for 25%, 21%, 11%, 35%, and 30%, respectively. The application of VRT will also indirectly affect the quality of PE in universities.

The existing stand-alone multimedia machines and online multimedia machines in the market have certain deficiencies, so they cannot meet the actual needs. Based on this, this research combines the actual needs to design and implement a multi-media system based on the Internet of Things and cloud service platform. Moreover, through in-depth research on the MQTT protocol, this study proposes a message encryption verification scheme for the MQTT protocol, which can solve the problem of low message security in the Internet of Things communication to a certain extent. In addition, through research on the fusion technology of the Internet of Things and artificial intelligence, this research designs scheme to provide a LightGBM intelligent prediction module interface, MQTT message middleware, device management system, intelligent prediction and push interface for the cloud platform. Finally, this research completes the design and implementation of the cloud platform and tests the function and performance of the built multimedia system database. The research results show that the multimedia database constructed in this paper has good performance.
