With the development of science and technology and the progress of wireless sensor network technology, a variety of intelligent electronic products are used more and more widely in people's lives. High technology and intelligent technology have entered residential home users from intelligent buildings, and home intelligent technology has become a cutting-edge technology topic. The development of mobile Internet provides a new platform for home decoration, which is of great significance in promoting the formation of smart families and smart communities. Curtain is an important element in interior decoration design. It is of great practical value to develop a mobile virtual display system that can manage curtains and provide curtain decoration effects. The design idea of modularization is adopted, and the design process of wireless communication module, relay module, key module, power protection and level conversion module of the system is emphatically analyzed. The basic working principle and operation method of the system are introduced, and the server and client software based on TCP communication protocol are designed to realize the remote control of curtains through the Internet or personal mobile devices. The actual results show that the scheme can be applied to the home or office environment, and has the characteristics of high stability and simple operation.

For a long time, some companies have basically no revenue, but have not delisted from the market with poor performance, reflecting the embarrassment of the system. One of the reasons for the difficulty of enterprise delisting is the existence of ST companies in the market, which results in the scarcity of shell resources of listed companies. How to optimize the market exit mechanism has become an urgent problem to be solved. This paper selects Chinese listed companies that were processed by ST from 1998 to 2020 as the research object, and uses survival analysis to study the survival problems of ST companies, that is, the time rule of ST companies' delisting and delisting. The results show that the probability of capping incidents of listed companies after the implementation of special treatment increases first and then decreases, reaching a peak in the second year after the implementation of ST, and a substantial decline in the third year, and it can be achieved in the sixth year and beyond. Few ST companies have decapitated; the probability of delisting events of listed companies after the implementation of special treatment also increases first and then decreases, reaching a peak in the third year after the implementation of ST. In the fifth year and beyond, few ST companies have retired. city.
