Car made in the world's first high-speed rail "intelligent maintenance robot"

Rail vehicle intelligent maintenance system by the car Qingdao Sifang Vehicle Research Institute Co., Ltd. (in the car Sifang) developed. The system consists of two parts: the control center and the image acquisition robot. The control center collects the collected images and dispatches the inspection process. The image acquisition robot collects the detection information of each part of the train. It mainly consists of an intelligent delivery platform, a flexible multi-degree-of-freedom machine Arms, cameras, sensors, surveillance cameras and other components. The system is the first device in the world that uses highly flexible robots and machine vision fusion technology to perform visual inspections of various parts of a vehicle in full compliance with high-speed train maintenance standards or urban rail train detection standards. When the train storage for maintenance, start the image acquisition robot for self-test, the robot arrived at the front of the vehicle uniform head position, the robot automatically detects the bottom of the vehicle images collected at the end of the picture; when the robot reaches the tail fixed position, the robot extension Out of the robot arm and reverse the direction of the robot laser positioning to the bogie position, the arm in accordance with the predetermined design into the narrow space at the bottom of the bogie and the vehicle, began to capture the key parts of the train pictures at the same time in the robot arm with the robot forward acquisition The picture, the robot automatically open the area camera, a more detailed bottom HD shooting. Compared with the traditional manual operation, the intelligent maintenance system can increase the overhaul range by over 40%, reduce the missed inspection rate and improve the maintenance efficiency. Train collection information will be displayed in real-time on the control center display. After the collection is completed, the robot will automatically return to the initial position and shut down. The old saying goes: "There are Sambo, the essence of God," the system also has three magic weapons, to ensure that the inspection of efficient, high-quality, high-definition image acquisition is clear, accurate fault identification and a variety of driver-compatible. HD image acquisition clear. The image acquisition robot can capture high-definition images of key parts of the bogie in all directions. The multi-degree-of-freedom flexible arm carries the image acquisition device to collect the top, side and bottom high-definition images of the bogie. Meanwhile, the line scan camera collects high-definition images of the entire body bottom, The array camera collects high-definition images of the bottom of the bogies to ensure full coverage of the vehicle to be examined. Fault recognition is accurate. Through the use of advanced image feature recognition technology and machine depth learning technology, greatly improve the accuracy of fault identification. The collected high-definition images are transmitted to the control center in real time through a wireless network, and the image is automatically detected by an image recognition algorithm, for example, component loss, loose bolts, foreign matter, rupture, size abrasion, etc. The system can automatically feed the information back to the maintenance Personnel to verify. Compatible with a variety of drive modes. According to the different conditions of maintenance work, the image acquisition robot can work in two ways: hanging or laying the rail on the ground, and is compatible with various working conditions. The maintenance mode can also be customized according to user requirements.
