Embodiment 1

[0025] see figure 2 , an embodiment of the present invention provides a railway turnout snow melting system based on laser surface heat treatment, including a laser and an environmental detection device, the laser and the environmental detection device are connected to a control terminal, and the environmental detection device is used to transmit a detection signal to the control A terminal, the control terminal is used for judging the ice and snow coverage of the railway switch according to the detection signal of the environment detection device, and outputting a control signal to the laser, so as to control the laser to perform laser surface heat treatment on the surrounding switch.

[0026] Further, the environment detection device includes a camera, and the camera is used to photograph the ice and snow coverage on the surrounding switch, and send the photographed picture to the control terminal, and the control terminal judges through image recognition whether the switch ...

Embodiment 2

[0037] see image 3 , the embodiment of the present invention discloses a method for melting snow of railway turnouts based on laser surface heat treatment, comprising the following steps:

[0038] The image information of the surrounding switch is captured in real time through the camera, and the image is transmitted to the control terminal;

[0039] The control terminal judges whether the turnout picture captured by the camera is covered with ice and snow through the image recognition algorithm. If it is detected that the turnout is covered with ice and snow, it controls the laser to start working;

[0040] The control terminal recognizes and accurately locates the range of the laser scanning switch through the image, and controls the laser to align the switch to scan and irradiate a certain area of ​​the switch, so that the temperature of the switch increases and the snow melts;

[0041] If the control terminal detects that the ice and snow on the switch is melted, the contr...

Abstract

The invention discloses a railway turnout snow melting system and method based on laser surface heat treatment, the system comprises a laser and an environment detection device, the laser and the environment detection device are connected with a control terminal, and the environment detection device is used for transmitting a detection signal to the control terminal; and the control terminal is used for judging the ice and snow covering condition of the railway turnout according to a detection signal of the environment detection device, outputting a control signal to the laser and controlling the laser to perform laser surface heat treatment on the surrounding turnout. One set of snow melting equipment can meet the snow melting requirements of multiple sets of turnouts around, the number of trackside equipment is small, the construction cost is low, the power consumption is low, and later daily operation and maintenance are facilitated.

Description

technical field [0001] The invention belongs to the technical field of railway construction, and in particular relates to a system and method for melting snow of railway turnouts based on laser surface heat treatment. Background technique [0002] At present, the snow melting of railway turnouts in the industry generally adopts electric heating. The snow melting system equipment consists of station control terminals, trackside electrical control cabinets, track temperature sensors, isolation transformers, electric heating elements and fixtures. The station control terminal controls the trackside electrical control cabinet, and achieves the purpose of snow melting through heating elements and rail heat conduction. like figure 1 As shown in the figure, using this electric heating method to melt snow on the turnout has a large number of trackside equipment, high engineering cost, high power consumption, and it is not easy for daily operation and maintenance in the later stage....
