The invention discloses a self-calibration and drift compensation method for an automatic underground water monitoring station, and the method comprises the following steps: 1, transmitting a reference measurement starting instruction to an underground bubble method device by an edge calculation gateway, forming a reference data pair by a bubble method water level reference value and a reference acquisition moment, and writing the reference data pair into a reference data cache region; 2, the edge computing gateway creates a state storage structure and a covariance storage structure; and step 3, the edge computing gateway reads a drift amount estimation value from the state storage structure as a drift compensation amount, and when a drift estimation standard deviation exceeds a set threshold, bubble method hardware reference acquisition is triggered. According to the invention, the problems of high manual calibration cost and lack of independent reference support in pure software estimation in the prior art are solved, so that a monitoring station can stably operate for a long time under an unattended condition and continuously output high-precision underground water level monitoring data.

The invention provides a method and a device in a node for wireless communication. The method comprises the steps that a first node executes AI prediction based on an artificial intelligence AI model to obtain a prediction result, and the prediction result is used for reflecting the signal quality of a candidate cell in a future time period; based on the prediction result, executing at least one of the following switching operations: sending the prediction result, receiving a switching instruction, and performing cell switching in response to the switching instruction, the prediction result being used for triggering a second node to execute switching preparation in advance; or, under the condition that the switching condition is met, performing cell switching based on the prediction result.
