In order to meet the needs of safety, durability and reliability for the battery management system, the data monitoring and diagnosis for the battery management system platform is researched and developed. The platform based on the CAN bus technology, in the VC++6.0 development environment, implement the battery management system running state monitoring, fault diagnosis, parameter configuration,...
Under many circumstances, you may want to monitor and control your home lighting system and appliances while you are away for work, travel, or vacation. Recently, two major technology developments have made this application possible. One catalyst is the wide adoption of high-bandwidth wireless networks in universities, hospitals, hotels, and other working environments. A second catalyst is the emergence...
Thomson scattering is reported for the first time to measure the electron density and temperature of aluminum laser plasma in air. Electron and excitation temperatures are compared to discuss local thermodynamic equilibrium in such plasmas.
We report an investigation of the optical performance of a conformal-shaped phosphor coating fabricated using pulsed spray techniques on horizontal LED chips. Both the nitride and YAG:Ce phosphor mixed configuration and the multilayer configuration were studied. Also, 3535-packaged LED devices with the two typical phosphor configurations were prepared and analyzed. The results revealed that the LED...
Moisture content of oil and paper is one of the most important factors influencing the dielectric behavior of insulation systems. Moisture estimation in insulating paper can provide a way to understand the real condition of insulation and helps to assess its remaining useful life. In recent years, Frequency Domain Spectroscopy (FDS) is widely used by power utilities for moisture estimation and condition...
The principle and design of the distributed optical fiber temperature sensing system based on Raman scattering is presented in this paper. The spatial resolution is enhanced by reducing the pulse width of the light source and high speed progressive average etc. The distributed optical fiber sensor not only has the characteristics of resistance to electromagnetic interfere, against fire and so on,...
With the development of smart grid, The distributed optical fiber temperature monitoring system has more and more applications in power cable monitoring area. this paper presents the technology of distributed optical fiber temperature monitoring system running on the power cable, it use to real-time online monitoring for the power cable temperature and carrying capacity, and through carrying capacity...
