The invention discloses a portable
catenary suspension state detection and
monitoring system, relates to the technical field of
catenary inspection, and can realize a picture-in-picture function, anda red square frame is set in a visual field image, so that under the condition that line basic data is inaccurate, a worker can quickly judge whether the contact suspension is in the visual field of the high-definition imaging CCD or not; with the adoption of the
system, panoramic high-definition imaging detection of the suspension state of the contact net in any section can be realized without moving a rail car and without completely depending on line basic data, so that the high cost of the moving rail car is saved, the
safety risk is reduced, and most importantly, comprehensive inspection of complex lines in
station branch lines and hub areas is realized. The operation state of equipment in the section can be mastered in time, the inspection
skylight requirement and labor investment arereduced, the operation risk is reduced, the
safe operation guarantee of the equipment is improved, meanwhile, the
system is easy to use, and the use and maintenance cost of the detection
system is greatly reduced.
