The reason why Xiaobai is so smart is that it adopts the integrated design idea of robot chassis + nuclear radiation detection module, applies laser guidance and machine image learning technology, and can automatically identify the container size and determine the action mode based on the in-depth learning of machine vision. Recently, the intelligent robot "Xiaobai", which can accurately locate the radiation source, accurately measure the radiation measurement, give audible and visual alarm and remotely communicate with customs officers, officially appeared in Tianjin Customs, adding a "sharp weapon" to protect the ecological security of the port. This is also the first time that intelligent robot equipment is used to realize full-automatic remote positioning and identification, radiometric detection and nuclide identification of inbound containers within the scope of national entry and exit ports. It can replace people to complete dangerous radiation detection "Report that Xiaobai has reached the designated position and started the operation!" At the supervision site of Tianjin Xingang customs, inspector Xue bin gently clicked the tablet computer. At the site of container stacking, the intelligent robot "Xiaobai", with dark blue chassis and white cylindrical fuselage and shape similar to a small tank, began to slowly detour around the target container according to his instructions for radiation detection. Suddenly, "Xiaobai" sent out a rapid beep alarm, and the tablet computer in Xue Bin's hand also gave a synchronous alarm, indicating that the target container has radiation and has exceeded the warning value. It is suggested to transfer the batch of goods to the isolation area immediately. After completing the inspection task of all containers, "Xiaobai" will return to the charging pile to replenish energy by itself and wait for the next task instruction. It is reported that this intelligent robot called "Xiaobai" is fully known as "5g + Remote radiation detection robot". It is jointly developed by Tianjin Customs laboratory and fangweishi company. It is mainly used for radioactive screening of imported goods. According to the relevant responsible comrades of the science and Technology Department of Tianjin Customs, in the past, when customs inspectors inspected containers suspected of containing radioactive substances, not only the detection and collection process was complex, but also there was the possibility of radioactive injury to personnel. In order to standardize and intelligentize the nuclear radiation monitoring process, make the monitoring data traceable, manageable and analyzable, and reduce the operation risk of customs inspectors, Tianjin Customs actively promotes the application of 5g + artificial intelligence technology in the field of customs supervision, allowing robots to replace people to complete the nuclear radiation monitoring with high risk and repeated operation. "Xiaobai" will also return the detection data in real time during the detection process. If abnormal conditions are found, it will automatically send alarm information to the inspection customs officer to provide a reliable reference for subsequent disposal. The optimal path can be determined during detection Compared with similar robots in the previous scene, "Xiaobai" is more intelligent. The operator only needs to press the start and end keys, and the rest of the work such as path planning, target finding and detection can be safely handed over to "Xiaobai" for automatic completion. The reason why Xiaobai is so smart is that it adopts the integrated design idea of robot chassis + nuclear radiation detection module, applies laser guidance and machine image learning technology, and can automatically identify the container size and determine the action mode based on the in-depth learning of machine vision. In the process of detour, the radiation detection values of 12 points of the target container can also be collected for 3 times, and the collected data can be automatically compared with the standard data, so as to accurately locate the location of the radiation source and obtain the radiation measurement. "In this application scenario, the size and size of the container are not uniform, and there are countless permutations and combinations of positions. People can detect the container by observing, approaching, selecting position and other actions, but this is still difficult for the robot and needs to be broken down into multiple steps." Dr. Han Wei, member of "Xiaobai" R & D team. Through machine vision technology, the R & D personnel have realized the accurate recognition of different container sizes, sizes and positions by the radiation detection robot; By developing the algorithm model of different number of containers and containers with different placement positions, the sequential detection and scanning of radiation dose of multiple containers by radiation detection robot is realized; At the same time, through the working mode of "coarse adjustment" and "fine adjustment", the control system is used to ensure that the radiation detector head always maintains an accurate detection distance of 10 cm from the surface of the container during the walking process of the robot. "The robot can also continuously improve its performance through deep learning. Even if it detects multiple irregularly stacked containers, it can also select the optimal path for detection." Han Wei introduced that the robot can work 24 hours a day, which can greatly improve the efficiency of customs inspection. At present, Tianjin Customs is actively exploring the business fields of container radiation detection robot in the future, such as patrol inspection of container yard and on-site inspection of dangerous chemical containers, so as to further improve the intelligent supervision ability of Tianjin Customs.
