Beschreibung
Zusammenfassung:	A hydraulic system fault locating method, comprising: determining maximum output power of a power system and maximum output power of a hydraulic system, and according to respective size relationships between the maximum output power of the power system and a preset power threshold, and between the maximum output power of the hydraulic system and the preset power threshold, determining whether to perform a health test on the hydraulic system; when determined to perform a health test on the hydraulic system, determining a hydraulic efficiency index of the hydraulic system, the hydraulic efficiency index comprising a single-action efficiency index and a compound-action efficiency index; when the single-action efficiency index is smaller than a corresponding preset single-action target efficiency index, determining a loop fault corresponding to a single action; when the compound-action efficiency index is less than a corresponding preset compound-action target efficiency index, determining a loop fault correspond
