Design Of Dual-spectral Image Fusion Corona Detection System

When the electric field intensity between a high-voltage equipment beyond acertain value, the gas between equipments will be locally breakdown and then bringout discharge phenomenon named corona discharge. As times gone a coronadischarge point will accumulated to a certain level and then produce ozone, nitrogenoxides and other gases which can be corrosive transmission line, more worse it canbe damage the power supply equipment, cause imponderable economy loss.Therefore, detect corona discharge points of the power supply equipment has veryimportant significance to reduce the economy losses. Visible and solar blind dualspectrum image fusion corona detection method has low false rate, high detectionefficiency that become a reliable and effective detection method. But coronadetection system based on dual spectrum image fusion often has insufficient energyutilization and image processing and video compression contradiction issue. So wedesigned a dual spectrum corona discharge detection system based onTMS320DM8148intend to resolve the problems.For dual spectrum image fusion corona detection system this paper has mainlycarried on the following works:(1) According to system functional requirements of the project, propose afeasible scheme.(2) Ultraviolet objective system design.(3)The main circuit system designed, PCB designed and do some signalreflection, crosstalk emulation of the high-speed signal of the system SDRAMmodules so that to ensure the correctness of the circuit system to normal, stable and reliable. Finally, each functional module of the main circuit system was bare metaltest.(4) transplant the Linux operating system and designed a video capture, displayprogram. Finally, via a detection experiment to verify the accuracy and practicalityof the system.
