In the high-voltage transmission line system, the accidents have often occurred, and as a result of power line icing accidents are particularly prominent. In this paper, the author presents a DSP-based image monitoring of high voltage transmission line method. This method is use of high-voltage transmission tower-lines camera to collect the high voltage transmission line image in real time, and directly processing the image in DSP. If wires normal, it will not send pictures to the center and if the abnormal occurred, it will calculate the thickness of ice covering wires, converting the image to JPEG. This article designed and implemented the DSP-based image monitoring of high voltage transmission line algorithm exception, run successfully in the simulation and emulation system which can be used for monitoring of high voltage transmission line icing conditions online.
