Therefore, the intelligent operation of the X-Screen has received more and more attention. At present, in the intelligent operation of the X-Screen, the power supply of the X-Screen is usually directly started after connecting to the power supply. There is no matching of the charging mode, which can easily cause the X-Screen to be overloaded or abnormal in voltage during operation, and cannot ensure the safe and stable operation of the X-Screen during charging. At the same time, the existing X-Screen brackets are mostly fixed and cannot be freely adjusted according to user needs, which makes it difficult to provide the best viewing angle and experience during operation, and cannot meet the user's high intelligence requirements for the X-Screen. In addition, heat will be generated during the operation of the X-Screen, so it is necessary to control the heat dissipation device for heat dissipation. However, due to the influence of external disturbances and other factors, there are uncertain errors in the parameters of the heat dissipation device, which makes it difficult to accurately control the heat dissipation effect, so that the heat dissipation treatment of the X-Screen fails to achieve the ideal effect, resulting in the reliability and safety of the X-Screen operation process cannot be effectively improved.
