Intelligent monitoring method and device for liquid level of oil and gas well

The invention relates to the field of artificial intelligence, in particular to an oil and gas well liquid level intelligent monitoring method and device. Characteristic data in the oil and gas well in the current time period are collected; calculating the abnormal degree of the feature data at each moment; calculating the transmission urgent degree of the feature data; grading the feature data in the current time period, and calculating an adjustment coefficient of the feature data of each grade; constructing an adjustment coefficient sequence of each level of feature data; performing Huffman coding according to the adjustment coefficient sequence of the feature data of each level in the current time period, correcting the duration of the next acquisition time period to obtain a coding result of each time period, and transmitting the coding result; and decoding the coding result to obtain oil and gas well characteristic data, and regulating and controlling oil and gas well parameters according to the abnorma
