Embodiment 1

[0027] The non-contact detection method of the high-speed rail ballastless track pavement information of the present invention comprises the following steps:

[0028] The first step is to install the infrared sensor on the track inspection trolley and adjust the working distance of the infrared sensor. The infrared sensor is connected to the microcontroller through a voltage divider circuit;

[0029] In the second step, the track inspection trolley drives the infrared sensor to travel on the track. The infrared sensor receives the reflected light signal of the track. The reflected light signal is converted into a voltage signal by a voltage divider circuit and sent to the single-chip microcomputer. The single-chip microcomputer obtains the infrared sensor by processing the voltage signal. The height data collected in real time, and then calculate the number of sleepers, sleeper uniformity and gauge data.

[0030] In the third step, the single-chip microcomputer sends the data ...

Abstract

The invention relates to the technical field of sleeper detection; in particular to a non-contact detection method for road surface information of a high-speed railway ballastless track, which comprises the following steps of: 1, installing an infrared sensor on a rail inspection trolley and adjust the operating distance of the infrared sensor, wherein the infrared sensor is connected to a single-chip microcomputer through a partial voltage circuit; 2, driving the infrared sensor to travel on the track by a rail detection trolley, wherein the infrared sensor receives the reflection light signal of the track, the reflection light signal is converted into voltage signal and sent to the single-chip microcomputer through the partial voltage circuit. By processing the voltage signal, the single-chip microcomputer obtains the real-time height data collected by the infrared sensor, and then the number of sleepers, the uniformity of sleepers and the gauge data are calculated. The method achieves non-contact automatic measurement of the number of sleepers, uniformity of sleepers and gauge data, and has high measuring reliability.

Description

technical field [0001] The invention relates to the technical field of sleeper detection; in particular, it relates to a non-contact detection method for ballastless track pavement information of high-speed railways. Background technique [0002] The existing sleeper identification technology is to measure the mileage and then estimate it based on the sleeper spacing. This method has errors and is not accurate enough for uneven sleeper spacing. [0003] Optical ranging technology is a mature technology in the industrial field. The principle is that the device emits a beam of light, hits the object, reflects it back, measures the intensity of the reflected light, and the time difference to judge the distance of the object. This kind of application is often used in the field of road distance measurement and speed measurement. The measuring light can be laser or infrared light. However, in the aspect of railway track detection, there is no precedent for its use. Contents ...
