The invention discloses a contact network suspension operating state intelligent detection system. The contact network suspension operating state intelligent detection system comprises a three-dimensional laser scanner and a laser scanning module, and further comprises a data processing module, a data transmission module, a data comparison module, a standard database module, an information output module and a data storage module; the data processing module, the data transmission module, the data comparison module, the standard database module, the information output module, and the data storage module are application software installed in a PC; the laser scanning module is a built-in control system of the three-dimensional laser scanner; and the PC is integrated into an inspection repair vehicle and can also be installed in a power supply section. The contact network suspension operating state intelligent detection system can perform intelligent identification and intelligent judgment, can quickly and accurately identify the operating states of various parts of the system, and can discover the problematic part in advance and process the problematic part in time; therefore, the occurrence of driving safety accidents is avoided, and meanwhile, the labor intensity of the detecting personnel is greatly reduced, the detection efficiency is improved, the accuracy of the detection is improved, and a guarantee for driving safety is provided.
