The invention provides a characteristic value selection method, a detection method and a system for detecting lifting equipment. The selection method comprises the following steps: acquiring the type and the value of a characteristic value of each equipment type in a normal state of the equipment; for each independent characteristic value type of each equipment type, obtaining an independent upper bound threshold value and an independent lower bound threshold value; obtaining an individual accuracy result based on the individual upper bound threshold and the individual lower bound threshold; acquiring a general characteristic value type according to each individual characteristic value type of each device type; acquiring a general upper bound threshold value and a general lower bound threshold value of each general characteristic value type; acquiring a universal accuracy result based on the universal upper bound threshold and the universal lower bound threshold; obtaining a comprehensive accuracy index based on the individual accuracy result and the general accuracy result; and selecting the combination of the characteristic values, and obtaining the characteristic value combination meeting the comprehensive accuracy index requirement and a corresponding threshold value. According to the invention, the comprehensive accuracy index suitable for all equipment types is obtained.
