TELEVISION DEVICE FOR MEASURING THE HEIGHT OF MAIN RODS OF CLAMPS ON THE SUPPORT OF A CONTACT NETWORK

摘要

This utility model relates to the field of diagnostics of the state of the wired contact network of electrified railways, and more specifically, to a television device for measuring the height of the main locking rods on the supports of the contact network, which is installed on the roof of the car to assess the state of the contact network of electrified railways of direct and alternating currents . The device for measuring the height of the main retainer rods on the supports of the contact network contains an optical unit that includes a left digital matrix television camera and a right digital matrix television camera, configured to register images in the field of view of cameras while the car is moving, while the field of view of the left and right digital matrix television cameras are oriented along the axis of movement of the car in the direction of the location of the pantograph collector in such a way as to obtain images of contact elements ktnoy network, located near the vertical plane of the runner collector, from different angles; the lighting unit, which includes the left searchlight, made with the possibility of highlighting the elements of the contact network in the field of view of the left digital matrix television camera, and the right searchlight, made with the possibility of highlighting the elements in the field of view of the right digital matrix television camera; a synchronization unit configured to synchronize the operation of the left and right digital matrix television cameras of the optical unit so that the cameras of the optical unit register images of the contact network elements simultaneously; and a processing unit configured to receive the first image from the left digital matrix television camera and the second image from the right digital matrix television camera, registered simultaneously, highlight elements of the contact network on the first and second images, overlay the graduated pixel coordinate grid, determine the coordinates in pixels selected elements of the contact network, determine the height in pixels of the skid of the current collector relative to the roof of the car and determine, on whether the main latch pin is in one vertical plane with the pantograph runner, moreover, if it is determined that the main pin bar is in the same vertical plane with the pantograph runner, then the processing unit is additionally configured to determine the height in pixels of the clamp pivot relative to the pantograph runner and summation a certain height in pixels of the skid pantograph relative to the roof of the car and height in pixels of the main rod of the latch relative to the skid toko riomnika for height in pixels main rod clamp on the catenary support carriage relative to the roof, and the processing unit is further adapted to recalculation height in pixels main rod clamp on the catenary support carriage relative to the roof in metric units for the linear calibration tables.
