背景技术Background technique
在铜、铅、锌、镍等金属的水溶液电解精炼、电解沉积的工业生产过程中，一般单个电解槽包含数十块阳极和对应数量的阴极，阳极板和阴极板交叉并排排列。电解槽上阴阳极之间空间狭窄，电极距离数十毫米，每块电极上承载的电流高达数百安培，电解槽上的进电侧母线、出电侧母线上的电流与电极上承载的电流形成了非常复杂的磁场环境，实际上，电极板电流的大小，直接关系到电解的电流效率、产品的质量、产品能耗等生产关键指标。电解槽上每块阴极、阳极上通过的电流是多少，一直没有相应的测量方法，人们只能按系列电流被阴极或阳极的平均数量平分来进行估计。In the industrial production process of electrolytic refining and electrolytic deposition of copper, lead, zinc, nickel and other metals in aqueous solution, generally a single electrolytic cell contains dozens of anodes and a corresponding number of cathodes, and the anode plates and cathode plates are arranged side by side. The space between the cathode and anode on the electrolytic cell is narrow, the distance between the electrodes is tens of millimeters, and the current carried by each electrode is as high as hundreds of amperes. A very complicated magnetic field environment is formed. In fact, the magnitude of the electrode plate current is directly related to the key production indicators such as the current efficiency of electrolysis, the quality of the product, and the energy consumption of the product. There is no corresponding measurement method for the current passing through each cathode and anode on the electrolytic cell. People can only estimate the series current by the average number of cathodes or anodes.

What the magnetic induction sensor detects is not only the magnetic field generated by the current passing through the current electrode, but also the magnetic field generated by other electrodes in the slot, especially the conductive rods of nearby parallel electrodes, and the magnetic field generated by the current on the overlapping busbar on the slot, The magnetic field generated by the large current on the bus outside the electrolyzer and the magnetic field generated by the current in the electrolyte are very complicated, so the total magnetic field strength of the electrolyzer is obtained.

At this time, the current passing through this electrode will be shared to other electrodes in the tank. The magnetic induction intensity measured at this time is the background magnetic field intensity when the current electrode works normally.
步骤103：根据所述总磁场强度以及所述背景磁场强度计算各所述电极的磁场强度。Step 103: Calculate the magnetic field strength of each of the electrodes according to the total magnetic field strength and the background magnetic field strength.
