The invention discloses a deflection detecting system, a deflection detecting method and a deflection detecting device of a suspension arm of engineering machinery and the engineering machinery, which have the advantages that detecting precision is high and the operation safety of engineering machinery can be improved. The deflection detecting system comprises a controller, two basic jib GPS (global positioning system) position finders and a measuring point GPS position finder, wherein the two basic jib GPS position finders are positioned on basic jigs of a crane jib, and the straight line formed by the two basic jib GPS position finders and is parallel to the central axes of the basic jigs along the crane jig; the measuring point GPS position finder is positioned at the to-be-detected deflection part of the crane jib; the two basic jib GPS position finders and the measuring point GPS position finder are respectively used for determining the self space coordinate information; the controller is used for acquiring the determined space coordinate information from the two basic jib GPS position finders and the measuring point GPS position finder respectively, and determining the deflection of the crane jib at the to-be-detected deflection part according to the space coordinate information of the two basic jib GPS position finders and the measuring point GPS position finder.
