通过整合LNG厂站储罐外部温度传感器的记录时间、所属厂站、储液罐编号、储液罐传感器编号、储液罐传感器坐标、储液罐传感温度、储液罐当时平均温度、储液罐最高温度差、同厂站储液罐平均温度、环境温度、储液罐温度监测结果等数据，得出LNG厂站储罐外部温度监测分析数据；可以用于通过实时监测LNG厂站储罐的外部温度，可以预防和及时应对可能的安全事故，如泄漏导致的局部温度降低、外部过热影响燃气低温储存等，确保LNG储罐的安全运行，为LNG接收站、天然气燃气供应公司、海上油田、天然气加工企业、工业用户等提供安全数据参考。1.数据采集：通过对LNG厂站储罐外部温度传感器的记录时间、所属厂站、储液罐编号、储液罐传感器编号、储液罐传感器坐标、储液罐传感温度、环境温度，进行采集整理汇总。
2.数据计算：储液罐传感器坐标以储液罐中心轴为基准轴，正南方向为基本面，根据传感器在外面表面相对正南方向顺时针位移度数与地面相对高度，组合形成储液罐传感器坐标；储液罐当时平均温度为当时同一储液罐的全部传感器温度的平均值；储液罐最高温度差为当时同一储液罐全部传感器温度中通过函数筛选最高温度与最低温度，求其差值；同厂站储液罐平均温度为当时同厂站内所有储液罐的全部传感器反馈温度的平均值；
3.预警判断：储液罐温度监测结果根据3种情况综合判断，当1种出现时为预警，当2种出现时为报警，当3种出现时为严重报警；1为单个储液罐传感温度大于环境温度10℃或小于环境温度5℃；2为储液罐最高温度差大于10℃；3为储液罐当时平均温度大于同厂站储液罐平均温度8℃或小于同厂站储液罐平均温度3℃。
4.数据应用：通过实时监测LNG储罐外部温度，预防和及时应对可能的安全事故，如泄漏导致的局部温度降低、外部过热影响燃气低温储存等，确保LNG储罐的安全运行。

This dataset is generated by integrating multiple data points including the recording timestamps of external temperature sensors installed on LNG plant storage tanks, affiliated plant/station information, storage tank identification number, sensor identification number, sensor coordinates, sensor-measured storage tank temperature, current average tank temperature, maximum temperature difference of the tank, average temperature of all storage tanks at the same plant, ambient temperature, and tank temperature monitoring results, to produce external temperature monitoring and analysis data for LNG plant storage tanks.

This dataset can be used to prevent and timely respond to potential safety accidents through real-time monitoring of the external temperature of LNG plant storage tanks, such as local temperature reduction caused by leakage, external overheating affecting cryogenic storage of natural gas, etc., ensuring the safe operation of LNG storage tanks, and providing safety data references for LNG receiving stations, natural gas supply companies, offshore oilfields, natural gas processing enterprises, industrial users, and other relevant parties.

1. Data Collection: Collect, organize and aggregate data including the recording timestamps, affiliated plant/station, storage tank ID, sensor ID, sensor coordinates, sensor-measured tank temperature and ambient temperature from external temperature sensors of LNG plant storage tanks.

2. Data Calculation: The sensor coordinates of the storage tank are determined by taking the central axis of the storage tank as the reference axis and the due south direction as the reference plane, combining the clockwise displacement angle of the sensor on the outer surface relative to the due south direction and the relative height from the ground. The current average temperature of the storage tank is the average value of temperatures measured by all sensors of the same storage tank at the current moment. The maximum temperature difference of the storage tank is the difference between the maximum and minimum temperatures screened via a function from all sensor readings of the same storage tank at the current moment. The average temperature of storage tanks at the same plant is the average value of all sensor feedback temperatures from all storage tanks at the same plant at the current moment.

3. Early Warning Judgment: The storage tank temperature monitoring result is comprehensively judged based on three scenarios: early warning when one scenario occurs, alarm when two scenarios occur, and severe alarm when all three scenarios occur:
1) The measured temperature of a single storage tank sensor is 10°C higher than or 5°C lower than the ambient temperature;
2) The maximum temperature difference of the storage tank exceeds 10°C;
3) The current average temperature of the storage tank is 8°C higher than or 3°C lower than the average temperature of all storage tanks at the same plant.

4. Data Application: Real-time monitoring of the external temperature of LNG storage tanks helps prevent and timely respond to potential safety accidents, such as local temperature reduction caused by leakage, external overheating affecting cryogenic storage of natural gas, etc., to ensure the safe operation of LNG storage tanks.
