Embodiment 1

[0060] as attached Figure 4 As shown, an embodiment of the rail crawling online monitoring terminal of the present invention specifically includes: a camera component 11 , an image processing unit 12 , a signal acquisition unit 13 , a communication unit 14 , a temperature measuring sensor 15 and a light source 16 . The camera component 11 shoots (collects) images (pictures) containing the measurement marker 4 , and the image processing unit 12 calculates the position information of the measurement marker 4 based on the image captured by the camera component 11 and sends it to the signal acquisition unit 13 . The light source 16 is used to supplement the light for the image capture of the measurement mark 4 by triggering the signal acquisition unit 13 under weak light conditions (such as at night or in dark environments such as tunnels and canyons). The light source 16 can use LEDs (Light Emitting Diode, short for light-emitting diode) module. The signal acquisition unit 13 c...

Embodiment 2

[0070] as attached figure 1 As shown, an embodiment of the rail crawling online monitoring system 10 of the present invention specifically includes: a monitoring conversion terminal 2, a big data center 3, a measurement identification 4, an access terminal 6, and more than one monitoring terminal as described in Embodiment 1 1 (for example, 1 to 200 groups of monitoring terminals 1 can be used to realize interconnection through Zigbee). The measurement mark 4 is fixedly connected to the rail 5 to represent the position of the rail 5, and the monitoring terminal 1 and the monitoring conversion terminal 2 realize the crawling amount and temperature measurement of the rail 5 and are interconnected through a wireless communication network (such as Zigbee or LoRa network). The monitoring conversion terminal 2 packages the wireless data (such as Zigbee or LoRa data) in the same network IP (Internet Protocol, the abbreviation of Internet Protocol), and uploads to the big data center ...

Embodiment 3

[0078] An embodiment of the online rail crawling monitoring method of the present invention, the monitoring terminal 1 includes a camera component 11 , an image processing unit 12 , a signal acquisition unit 13 , a communication unit 14 , a temperature measuring sensor 15 and a light source 16 . The rail crawling online monitoring method specifically includes the following steps:

[0079] S10) The measurement mark 4 is fixedly connected to the rail 5, and the image containing the measurement mark 4 is taken by the camera assembly 11;

[0080] S20) The image processing unit 12 calculates the position information of the measurement mark 4 according to the image taken by the camera assembly 11 and then sends it to the signal acquisition unit 13; under weak light conditions, the light source 16 is triggered by the signal acquisition unit 13 to shoot the measurement mark 4. The image is filled with light;

[0081] S30) The signal acquisition unit 13 collects the rail temperature s...

Abstract

The invention discloses a steel rail crawling online monitoring terminal, system and method. The monitoring terminal comprises a camera assembly, an image processing unit, a signal acquisition unit, a communication unit, a temperature measurement sensor and a light source. The camera assembly shoots an image containing a measurement identifier, and the image processing unit calculates position information of the measurement identifier according to the image shot by the camera assembly and then sends the position information to the signal acquisition unit. The light source is used for supplementing light for image shooting of the measurement identifier through triggering of the signal acquisition unit under a weak light condition. And the signal acquisition unit simultaneously acquires a steel rail temperature signal measured by the temperature measurement sensor, and sends the steel rail temperature signal and the position information of the measurement identifier to the outside through the communication unit. The technical problems that an existing line steel rail state monitoring system is installed and measured in a contact mode, potential safety hazards to a line are large, and maintenance is difficult can be solved.

Description

technical field [0001] The invention relates to the technical field of rail engineering machinery, in particular to a terminal device, system and method for on-line monitoring of rail crawling. Background technique [0002] During the operation of the line, due to factors such as changes in ambient temperature, deflection of the rail under dynamic load, and longitudinal force of the train, the rail often appears to crawl. The crawling phenomenon of the rail is likely to cause damage to fasteners and other auxiliary equipment, thereby increasing the wear on the side of the rail, and also causing irregularities such as rail expansion, line distortion, and rail direction changes. In severe cases, it may lead to rail breaking accidents. In order to ensure the safety of railway operation, railway workers need to measure the amount of rail crawling on a regular basis, and record the local climate conditions. Based on the analysis of the measurement data, carry out stress relief an...
