Image denoising is an important step in image processing of pools intelligent life-saving system, adaptive denoising algorithms has based on wavelet in this paper. Firstly, the threshold value selection was discussed and then the effect of threshold functions on denoising result was evaluated. Finally, an improved adaptive nonlinear threshold function was put forward. Simulation results showing that the adaptive denoising algorithm designed in this paper can achieve higher PSNR value, and time cost can be satisfy the real-time demand of pool intelligent life-saving system simultaneously.

Besides biotechnology, nano-CT, the ideal technology, can also be used to observe three-dimensional nanostructures in intact cells as part of research into the characteristics of tight oil characteristics. There are few applications in the process and it is still in the early stage of development, but the advantages shown by 3D nanostructure technology are very strong and have strong applicability. Even in the face of tight oil reservoirs with poor physical properties, rapid decline in oil production after volume fracturing, and low oil recovery, it also shows very strong advantages. In order to promote the study of tight oil characteristics and avoid various problems, this article studies the characteristics of tight oil reservoirs based on nano-CT. The results show that the introduction of nano-CT technology into the study of tight oil reservoir characteristics can meet the market demand of tight oil and increase by 3.54%. It can continuously expand and develop rich oil resources under the condition of protecting geology and reservoirs, providing strong technical support for the next generation of large-scale tight oil storage and efficient growth, and can be used to a certain extent for research. The resulting reservoir characteristics solve the problem of excess resources.

Driven by the interests of the construction unit, field workers illegal operations and other reasons, tower crane collapse accidents occur frequently, personal injury or death became common occurrence. According to the nationalGB12602-2010 lifting mechanical overload protection device security technical specifications, security and monitoring equipment must be installed on the tower crane. The GPRS and U disk storage tower crane control system has catered to the national security specified requirements. By the control system, the data can not only be recorded and inquired, well it can also be wireless remote transmitted. Supervisors who are in units can also monitor the construction site online. Meanwhile, the system can control the tower crane operations according to the specific situation of overrun. The system has a good promotional value.
