This paper mainly discusses the basic concept,technical architecture,application advantages,and policy support of the"Photovoltaic-Energy Storage-Direct Current-Flexible"(PEDF)new-type building power system,and analyzes practical application cases.By conducting a detailed analysis of the four key technologies—photovoltaic power generation,energy storage systems,direct current distribution,and flexible electricity use—the potential and prospects of the PEDF system in achieving building energy conservation and emission reduction,enhancing grid interactivity,and promoting the efficient utilization of renewable energy are revealed.
At the present stage,the scale of highway construction projects in China continuously expands,which brings great convenience to the daily travel of the people and meets the needs of communication in various places.However,in the application process,the highway often appears a variety of disease problems,so the maintenance is required.At present,preventive maintenance technology has been widely applied,and has improved the actual maintenance effect.Therefore,this paper analyzes the application of asphalt road preventive maintenance technology in highway maintenance.
Due to the variability and complexity of landscape design in space and time, it is difficult to accurately express landscape design only by relying on individual hand-drawn effects and text descriptions. Based on this, the application research of virtual reality technology in the integrated design of architectural landscape is carried out. First, through the analysis of virtual reality technology, the advantages of virtual reality technology are explored in depth, and then the advantages of virtual reality technology are applied to the 3D landscape modeling design. Finally, application examples are analyzed. The results show that the entire roaming scene more truly reflects The local topography and landforms realistically simulate the local architectural landscape and restore the damaged characteristic town. The average FPS of the user roaming scene on an ordinary computer is not less than 18 frames/s, and the browsing is basically smooth.
Coal is one of the important energy resources in China,and the construction of coal mine dispatching informatization is of great significance in improving coal production efficiency,reducing costs,and optimizing resource allocation.Based on this condition,this paper analyzes the significance,problems and effective measures of coal mine dispatching informatization construction,including strengthening technical support and personnel training,improving information security and data quality,realizing the organic connection between informatization and business processes,and improving management level and decision-making ability,which has certain guiding significance for promoting the coal mine dispatching informatization construction.
With the rapid development of China's market economy,higher requirements are put forward for product quality,and it is necessary to ensure that product quality meets market demand,which puts forward higher requirements for enterprises to carry out metrology testing work.In addition,scientific researchers are required to conscientiously perform the research of metrology testing technology from the perspective of market supervision.Therefore,this paper discusses the influencing factors and optimization countermeasures of metrology testing quality,so as to play a positive role in promoting the development of metrology testing in China.
