The invention relates to a railway contact network detection device and method based on a quadrotor unmanned aerial vehicle. The method starts from inspection projects and working environments of railway overhead line system detection work, the modules which are relatively mature at present are combined, a four-rotor unmanned aerial vehicle (4) flies, the movement of the detection device along thecontact line is realized, the detection work of relevant parameters of the railway overhead line system is completed, a mobile data receiving console (2) is used for transmitting detection data to the ground through a wireless communication module (32), multiple detection functions of overhead line system conductor height and pull-out value measurement, overhead line system heating fault diagnosis, contact suspension state detection and the like are integrated, and the contact network state parameters are detected by the detection device, so that the detection work of the contact network is completed, the rationality of design and the intelligence of operation are embodied no matter whether the structure design of the detection device or the corresponding function is realized, the operation of workers is greatly facilitated, and the working efficiency of detecting and maintaining the main state parameters of the contact network is effectively improved.
Description
technical field [0001] The invention relates to a railway catenary detection device and a detection method based on a four-rotor unmanned aerial vehicle, belonging to the technical field of railway catenary detection. Background technique [0002] The catenary is a transmission line erected along the railway line and used to supply power to electric locomotives. It is mainly composed of contact suspensions, support devices, positioning devices, pillars and foundations. In the construction process of my country's high-speed electrified railway, high-speed catenary is inseparable, especially the high-speed catenary with superior structure, performance and other aspects, so as to give full play to the performance and cooperation of pantograph and catenary. However, the high degree of pantograph-catenary matching requires railway builders to accumulate experience in years of work, be meticulous in the calculation of various data, and use the optimal method to match the pantograp...
