China's urbanization and the economic development in southwest region gives rise to a higher requirement on the townscape construction of small towns. A better landscape of small towns can improve their environment by integrating natural environment with urban environment, which lays a strong foundation to create characteristic garden town. On the other hand, good landscape of small towns can highlight...
The measure system in power plant based on Orthogonal frequency division multiplexing technology was put forward after the signal sources are described firstly, connected with communication and monitoring networks existed already. In this system, wireless sensor networks or carrier transmission on power line or fiber-optic is used in fully mechanized working face and electric power line systems is...
Geology circumstance of mine seam is extremely complicated and there are many hidden trouble. After analyzed the existing current problems underground mine communication system, a kind of comprehensive information communication system based on the multicarrier modulation technology was designed. This system makes wire communication combined mutually with wireless communication by tandem adapter. In...
High power electromagnetic pulse (EMP) can easily couple into the inner of targets via lots of slots. To calculate the EMP coupling effects on a cylinder object with openings, the coupling course is simulated using FDTD method in this paper. Gauss pulse and double exponential pulse are selected as the incident pulse source. The coupling EM field strength E inside the object and the current density...
For the feasibility study of planning UHV (Ultra-High Voltage) AC/DC hybrid grid, real time simulation test using digital/analog hybrid simulator should be implemented other than offline simulation. The digital/analog hybrid simulator includes digital models, analog simulator, and interface devices. Limited by the testing equipment, dynamic-equivalent should be accomplished first for the grid to be...
