8, B: when a motor car is started, the pantograph slide plate (3) can be contacted with a contact line so as to provide power for the motor car, the pantograph slide plate (3) is easy to be subjected to small impact when being rubbed along the bottom surface of the contact line to form small off-line sparks, if continuous off-line sparks occur for a long time, the pantograph slide plate (3) and the contact line are easy to be ablated, when the pantograph slide plate (3) and the contact line generate electric arcs, certain heat can be emitted instantly, the infrared temperature detection module (12) can capture the heat of the electric arcs generated by the pantograph slide plate (3) and the contact line and then carry out thermal imaging and send the heat to an external PC (personal computer) end, because the larger the electric arc generates heat and the larger the heating area, the smaller the electric arc generates heat and the smaller the heating area, and the data captured by the infrared temperature detection module (12) can compare the size of the electric arcs, therefore, the abrasion degree between the contact net and the pantograph slide plate (3) is judged, the deformation of the buffer (21) can be detected through the buffer detection module (11), so that the pressure between the pantograph nets is judged, and then whether the arc generated by intermittent separation is generated due to insufficient pressure or the arc generated by abrasion between the pantograph nets is judged.
9, C: when the motor car drives the pantograph slide plate (3) to pass through the detection frame (4), the pantograph goat horn detection module (41) can be used for photographing and detecting the pantograph goat horn, when the pantograph slide plate (3) passes through the lower part of the pamm transparent plate (5), red light, yellow light and green light can be reflected because the color-changing graphene layer (31) is damaged on the surface, a light beam cannot be reflected in a perfect area, microcracks which are difficult to observe by human eyes can be provided through the color-changing graphene layer (31), a light-emitting light source on the pamm transparent plate (5) can illuminate the color-changing graphene layer (31) on the pantograph slide plate (3), then the image acquisition module (52) can capture the color-changing graphene layer (31), images acquired by the image acquisition module (52) can be transmitted to the PC terminal, and then the acquired images are stored by the image storage module, the color pattern recognition module on the PC end carries out recognition analysis on the collected image, thereby obtaining the wearing condition of the color-changing graphene layer (31), people can obtain the microscopic wearing condition on the color-changing graphene layer (31) in time, the wearing information of the color-changing graphene layer (31) can be obtained in time, people can replace the color-changing graphene layer in time, the phenomenon that the color-changing graphene layer (31) is contacted with a contact net to cause off-line phenomenon due to the wearing of the color-changing graphene layer (31) is avoided, electric arc is generated to damage the contact line, a detection frame (4) is arranged on a railway at a certain distance, when the railway runs through the section of the route, the image collection module (52) is used for detecting the color-changing graphene layer (31), if the wearing degree of the color-changing graphene layer (31) is intensified, the deformation of the buffer (21) detected by the buffer detection module (11) is within the specified deformation, the electric arc that infrared temperature detection module (12) detected produces more, and the contact net that so contacts with discolour graphite alkene layer (31) probably wears seriously, needs in time contact maintenance personal to salvage the contact net of this highway section.
