2.数据计算：读取上报时间、断电电位、镁包开路电压，通过选定当前时间前24h的断电电位和镁包开路电压，通过AVERAGE函数计算24h平均断电电位和24h平均镁包开路电压；以上报时间为横坐标，断电电位为纵坐标，建立坐标系，以通过选定当前时间前24h的断电电位为本次计算数据样板，通过SLOPE函数计算获得24h断电电位变化斜率，同理以镁包开路电压为纵坐标时，通过SLOPE函数计算获得24h镁包开路电压变化斜率。
3.状态评估：当当前断电电位与24h平均断电电位均小于-0.5V，同时当前镁包开路电压与24h平均镁包开路电压均小于-1V时，同时24h断电电位变化斜率与24h镁包开路电压变化斜率均小于0.001时，阴极保护监测状态为正常；上述项目有1-3项大于标准时，阴极保护监测状态为待维护；当上述项目有4项及以上大于标准时，阴极保护监测状态为异常报警。
4.数据应用：用于实时监控燃气管网的阴极保护状态，及时发现保护不足或失效的区域，便于维护和整改。

This dataset is generated by integrating data including monitoring point number, reporting time, off-potential, magnesium anode open-circuit voltage, 24-hour average off-potential, 24-hour off-potential change slope, 24-hour average magnesium anode open-circuit voltage and 24-hour magnesium anode open-circuit voltage change slope from gas pipeline network cathodic protection monitoring devices, to obtain cathodic protection status monitoring and analysis data for gas pipeline networks. It can be used for real-time monitoring of the cathodic protection status of gas pipeline networks, ensuring that pipelines are under effective anti-corrosion protection, preventing safety accidents and economic losses caused by corrosion, meanwhile evaluating the effectiveness of the cathodic protection system, timely identifying areas with insufficient or failed protection through data analysis to facilitate maintenance and rectification.
1. Data Collection: Collect, organize and summarize the reporting time, off-potential and magnesium anode open-circuit voltage from the gas pipeline network cathodic protection monitoring devices.
2. Data Calculation: Read the reporting time, off-potential and magnesium anode open-circuit voltage. Select the off-potential and magnesium anode open-circuit voltage within the 24 hours prior to the current time, and calculate the 24-hour average off-potential and 24-hour average magnesium anode open-circuit voltage using the AVERAGE function. Establish a coordinate system with the reporting time as the x-axis and the off-potential as the y-axis, take the selected off-potential data within the 24 hours prior to the current time as the calculation sample for this time, and obtain the 24-hour off-potential change slope using the SLOPE function. Similarly, when taking the magnesium anode open-circuit voltage as the y-axis, calculate the 24-hour magnesium anode open-circuit voltage change slope using the SLOPE function.
3. Status Assessment: The cathodic protection monitoring status is classified as normal when both the current off-potential and 24-hour average off-potential are less than -0.5V, both the current magnesium anode open-circuit voltage and 24-hour average magnesium anode open-circuit voltage are less than -1V, and both the 24-hour off-potential change slope and 24-hour magnesium anode open-circuit voltage change slope are less than 0.001. The status is marked as to-be-maintained when 1 to 3 of the above indicators exceed the specified thresholds, and as abnormal alarm when 4 or more of the above indicators exceed the thresholds.
4. Data Application: This dataset is used for real-time monitoring of the cathodic protection status of gas pipeline networks, timely identifying areas with insufficient or failed protection to facilitate maintenance and rectification.
