specific Embodiment approach 1
[0032] Specific implementation mode one: refer to figure 1 Describe this embodiment in detail, a kind of image recognition-based method for fault identification of railway freight car fire protection panels described in this embodiment includes the following steps:
[0033] step one:
[0034] Collect pictures of the upper fire panels of the bogies of different types of railway wagons at different times, places and environments from the large network database or the actual application environment, and then stretch, rotate and mirror each of the collected pictures separately, A sample library is established by using all the pictures before and after the transformation, and the pictures of the fire board on the upper part of the bogie include pictures of the fire board in a normal state and pictures of the fire board in a fault state.
[0035] For example: collect a picture of a fireproof board, then copy three identical pictures, and then stretch, rotate, and mirror the three c...

The invention relates to an image recognition-based fault identification method for a fire protection board of a railway freight car, which relates to the technical field of fault identification of railway freight cars. The invention aims to solve the problems that manual detection of fireproof panel faults of trucks is prone to missed detection and low efficiency. The present invention installs high-definition imaging equipment on both sides and the center of the track of the truck, and acquires the image of the fireproof board on the upper part of the bogie after the truck passes the installation position of the equipment. Use the deep learning network Faster rcnn network to detect faults in the state of fire board loss, falling off and damage, and use automatic image recognition to replace manual detection of fire boards, improve fault identification and detection efficiency, and reduce labor costs; apply deep learning to fire board failures In detection, the robustness and accuracy of the algorithm can be effectively improved.
Description
technical field [0001] The invention belongs to the technical field of railway freight car fault identification. Background technique [0002] Train fire is one of inertial accidents in traffic. In order to solve this problem, the Ministry of Railways has taken various measures, including adding fire-proof boards to trucks. Fire-resistant board, also known as fire-resistant board, is scientifically called thermosetting resin-impregnated paper high-pressure laminated board. It is a fire-resistant building material that can play a certain role in fire prevention and fire resistance. Although with the increase of the use area of the fireproof board and the improvement measures such as increasing the distance from the floor, the fire prevention effect has been strengthened. However, due to insufficient protection measures and failure to detect damage to fireproof boards in time, fire accidents have not been eliminated, which still threatens transportation safety and causes e...
