The invention discloses a method for detecting characteristic parameters of a locomotive pantograph in a non-contact mode. The method comprises the steps that firstly, an optical fiber temperature measuring sensor with the induction range covering a pantograph net contact is fixedly installed on a pantograph underframe; in pantograph-catenary contact temperature non-contact detection, a temperature collection module collects the temperature of a pantograph-catenary contact in real time when a train runs, noise reduction processing is conducted on the environment temperature background, and the obtained temperature of the pantograph-catenary contact is conveyed to a closed-loop adjustment module; based on contact temperature non-contact detection of a pantograph detection system, pantograph and contact net contact temperatures representing pantograph-catenary dynamic contact force, pantograph-catenary following and current collection characteristics are obtained and compared with a pre-established contact temperature-contact coupling degree parameter table, and an adjustment curve and a selection control strategy are calculated according to a comparison result; and the parameter reporting module reports information such as adjustment process data and equipment faults to the vehicle-mounted driving safety monitoring system. The method is low in investment cost, high in automation degree, good in real-time performance and reliable in detection.
