Detection and early warning method and system for camber on crane

The invention discloses a detection and early warning method and system for camber on a crane, and relates to the technical field of data processing.The method comprises the steps that crane main beam end positioning information is obtained, one piece of crane main beam end positioning information serves as a starting point, and an extension angle is determined; acquiring an acquisition rule based on the positioning coordinate information and the extension angle of the starting point; executing an acquisition rule to obtain crane acquisition data under multiple acquisition conditions, inputting the crane acquisition data into the self-adaptive calibration model for upper camber calculation, and checking based on an upper camber calculation result to determine an upper camber deviation value; and judging whether the upper camber deviation value reaches an early warning condition or not, and sending early warning information when the upper camber deviation value reaches the early warning condition.
