Design and Implementation of Anode Voltage Drop Acquisition and Transmission System for Aluminum Electrolysis
In order to monitor the change of anode voltage drop stably and accurately for a long time in the high temperature,high corrosion and strong electromagnetic environment of aluminum electrolysis site,an anode voltage drop acquisition and trans-mission system was designed.The system used STM32 microprocessor as the core,controlled the multi-channel acquisition module to collect the anode voltage drop signal in real time,and used the high-precision analog to digital conversion module to convert the analog anode voltage drop signal into digital signal,and transmitted it to the monitoring server through the Ethernet communication module.Finally,the system was installed in the actual field for testing.The experimental results show that the error of the anode voltage drop signal monitored by the system is less than 2%,and it can run stably for a long time.
