The invention provides a method used for identifying the temperature of an electrolytic cell polar plate. The method comprises the following steps that: S1: obtaining the visible light image and the thermal image of the electrolytic cell, and carrying out corresponding registration on the visible light image and the thermal image to obtain a space position thermal image; S2: matching the visible light image independently with the standard edge templates of the electrolytic cell and the polar plate to obtain the space position image; and S3: on the basis of the space position thermal image andthe space position image, identifying the real-time temperature value of the polar plate. By use of the method used for identifying the temperature of the electrolytic cell polar plate, the accuracy and the reliability of polar plate temperature identification can be effectively improved.
Description
technical field [0001] The invention relates to image processing technology, and more particularly, to a method for identifying the temperature of the pole plate of an electrolytic cell. Background technique [0002] In the process of copper electrolysis, the second half of the thick copper is pre-made as the anode, and the pure copper is made into a thin sheet as the cathode, which is inserted into the electrolyte at intervals. After electrification, copper dissolves into copper ions from the anode, and moves to the cathode, obtains electrons after reaching the cathode, and deposits pure copper at the cathode. [0003] In copper electrolytic refining, the current efficiency and grade rate are important indicators for assessing the efficiency and capacity of electrolytic production, and the short circuit between electrodes will have a negative impact on the above two indicators. When a short circuit occurs between electrodes, on the one hand, part of the electric energy wil...
