In order to meet the requirements of large-scale infrastructure and supporting equipment for corrosion monitoring in atmospheric environment, a multi-channel atmospheric corrosion monitoring system based on STM32F407ZGT6 is designed and implemented, aiming at the shortcomings of poor real-time performance and low monitoring accuracy in the existing corrosion monitoring system. The system combines the electrochemical impedance spectroscopy measurement technology and the theory of the equivalent circuit model of the galvanic probe of the double electrode primary battery, uses the time division multiplexing method to control the multi-channel excitation signal generation module to generate the excitation signal to act on the electrode system of each channel, uses the multi-channel response signal acquisition module to collect the response voltage data generated by the electrode system of each channel in real time, and transmits the calculated and processed electrochemical impedance spectroscopy data to the upper computer software deployed in the cloud server through the wireless communication module, and finally analyzes and processes the electrochemical impedance spectroscopy data to obtain the corrosion state information. The experimental results show that the system can realize multi-point corrosion status analysis and monitoring in atmospheric environment, the accuracy of corrosion rate is more than 90%, and the monitoring data can be accurately transmitted to the monitoring platform in real time.

为了满足大型基础设施及配套设备大气环境下腐蚀状态监测的需求,针对现有腐蚀状态监测系统中存在实时性差、监测精度低的缺点,设计实现一种基于STM32F407ZGT6的多通道大气腐蚀监测系统。该系统结合电化学阻抗谱测量技术与双电极原电池电偶探针等效电路模型理论,采用时分多路的方式控制多通道激励信号产生模块产生激励信号作用于各通道的电极系统,利用多通道响应信号采集模块实时采集各个通道电极系统产生的响应电压数据,将计算处理后的电化学阻抗谱数据通过无线通信模块传输至部署在云端服务器的上位机软件,最后分析处理电化学阻抗谱数据,获得腐蚀状态信息。实验结果表明,系统可以实现大气环境下多点位的腐蚀状态分析监测,腐蚀速率的准确度在90%以上,且监测数据可以实时准确的传递至监测平台。

为了满足大型基础设施及配套设备大气环境下腐蚀状态监测的需求,针对现有腐蚀状态监测系统中存在实时性差、监测精度低的缺点,设计实现一种基于STM32F407ZGT6的多通道大气腐蚀监测系统。该系统结合电化学阻抗谱测量技术与双电极原电池电偶探针等效电路模型理论,采用时分多路的方式控制多通道激励信号产生模块产生激励信号作用于各通道的电极系统,利用多通道响应信号采集模块实时采集各个通道电极系统产生的响应电压数据,将计算处理后的电化学阻抗谱数据通过无线通信模块传输至部署在云端服务器的上位机软件,最后分析处理电化学阻抗谱数据,获得腐蚀状态信息。实验结果表明,系统可以实现大气环境下多点位的腐蚀状态分析监测,腐蚀速率的准确度在90%以上,且监测数据可以实时准确的传递至监测平台。

In order to meet the requirements of large-scale infrastructure and supporting equipment for corrosion monitoring in atmospheric environment, a multi-channel atmospheric corrosion monitoring system based on STM32F407ZGT6 is designed and implemented, aiming at the shortcomings of poor real-time performance and low monitoring accuracy in the existing corrosion monitoring system. The system combines the electrochemical impedance spectroscopy measurement technology and the theory of the equivalent circuit model of the galvanic probe of the double electrode primary battery, uses the time division multiplexing method to control the multi-channel excitation signal generation module to generate the excitation signal to act on the electrode system of each channel, uses the multi-channel response signal acquisition module to collect the response voltage data generated by the electrode system of each channel in real time, and transmits the calculated and processed electrochemical impedance spectroscopy data to the upper computer software deployed in the cloud server through the wireless communication module, and finally analyzes and processes the electrochemical impedance spectroscopy data to obtain the corrosion state information. The experimental results show that the system can realize multi-point corrosion status analysis and monitoring in atmospheric environment, the accuracy of corrosion rate is more than 90%, and the monitoring data can be accurately transmitted to the monitoring platform in real time.
