Problems solved by technology

The method of measuring the track parameters of this kind of vehicle still adopts the traditional steel wire spiral measurement method. This method is limited by factors such as the quality and tension of the steel wire spiral itself, so that the speed and accuracy of the track parameter measurement are different. degree of influence

Embodiment

[0022] (1) There are four measuring trolleys at the front, middle, rear and end points in the work area, and a solid-state photoelectric receiving device is installed on the middle measuring trolley; an LED incandescent lamp is installed in the middle of the front measuring trolley wheel; the distance between the left and right sides of the rear measuring trolley is 300mm from the center of the line One LED incandescent lamp is installed at each place, and one LED incandescent lamp is installed in the middle of the terminal measuring trolley, which is used for the line direction measurement of the four-point method;

[0023] (2) Install the two independent photoelectric systems in the solid-state photoelectric receiving device in the middle of the measuring trolley in front and rear directions. The front photoelectric system receives the light from the lighting source in the middle of the front measuring trolley, and the rear photoelectric system measures the left and right on t...

Abstract

The invention relates to a railway line parameter optoelectronic test device for a tamping vehicle and detection method thereof. The invented device is characterized by comprising a solid optoelectronic receiving set and a luminous light source. The solid optoelectronic receiving set is composed of four optical imaging lens arrays, four CCD charge-coupled devices and a corresponding treatment circuit board, and an independent electro-optical system is formed of each two optical lens arrays and two CCD devices. The beneficial effects of the invention are: the invented device quickly acquires optical signals reflecting railway line parameters by using a high-precision linear array CCD photoelectric sensor and obtains line parameters by calculating using a computer software. The obtained parameters are transmitted to the tamping vehicle control system host to increase speed and accuracy of tamping vehicle surveying orbit parameters.

Description

technical field [0001] The invention belongs to a device for measuring railway line parameters in a railway inspection and maintenance vehicle (tamping car), in particular to a photoelectric testing device for railway line parameters used in a tamping car and a detection method thereof. Background technique [0002] In order to adapt to the rapid development of the national economy, the speed of the railway transportation system is constantly increasing. The increase in the speed of the vehicle will inevitably require the detection and repair equipment of the track to work at a higher speed and efficiency, so as to repair and ensure the safety of the vehicle in high-speed operation. Safety. Although our country has successfully developed a special vehicle that can simultaneously detect and repair track parameters - a tamping vehicle. The method of measuring the track parameters of this kind of vehicle still adopts the traditional steel wire spiral measurement method. This m...
