Abstract

In this paper an infrared system for short-circuit detection in the copper electrorefining process is presented. The system consists of an IR-camera, a computer, radiomodems and software including the developed algorithm to process a thermal image. The basic component of the proposed system is an infrared camera mounted in an air-conditioned protection unit on a moving crane. The video output of the infrared camera is connected to the input of a framegrabber card in a computer. The framegrabber card with software captures a thermal image of the electrolytic cell, then processes it to locate the hot spots (short-circuits in a cell). The inspection results are transferred directly by radio link to the control room to be printed and further processed. The system presented in this paper is a prototype that has been tested for several months. The test results indicate that strong short-circuits can be detected with the proposed system as reliably as with a currently used manual method (gaussmeter). The advantages of the proposed system are easier and faster measurements (all cathodes in a cell can be measured remotely at the same time) and possibility to gather new process information.
