Abstract

The invention discloses a speed measurement radar for the rail transit, and the radar comprises a housing, a wave-transparent plate, two high-frequency assemblies stored in the housing, a circuit board, and a circuit control board. The bottom of the housing is provided with an opening, and the opening is provided with the wave-transparent plate. Transmission signals of the two high-frequency assemblies pass through the wave-transparent plate in an inclined manner, and the transmission angles of the two high-frequency assemblies form an inclined angle which is within the range from 5 degrees to 15 degrees. The circuit board and the circuit control board are disposed in the housing, and are respectively connected the two high-frequency assemblies. The beneficial effects of the invention lie in that the structure is simple and practical, the radar is not affected by the slipping and idling of wheels, the installation is convenient, and the radar is resistant to dust and water.

Description

technical field [0001] The invention relates to a speed measuring radar, in particular to a speed measuring radar for railway track traffic. Background technique [0002] Railway track traffic speed measurement radar is developed along with the development of high-speed railways, because the previous railway speed measurement uses photoelectric encoder sensors to measure speed, and they measure speed through the rotation of the wheel shaft. Replacement, low precision and other defects. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a speed measuring radar for railway rail traffic, which has a simple and practical structure, is not affected by wheel slippage and idling, is easy to install, and is dustproof and waterproof. [0004] The present invention is achieved through the following technical solutions. [0005] A railway track traffic speed measuring radar, comprising a housing, a wave-transmitting plate, t...
