Abstract
Aiming at the problem of high packet loss rate in the traditional 3D laser scanning data transmission system, a 3D laser scanning data transmission system based on fuzzy algorithm is designed. The operational amplifier is used as the analog front-end of ADC, and the high-performance controller is selected to meet the needs of system development. By programming the FPGA chip, the state control of the transmission module and the configuration of each chip are realized. The data is preprocessed by three-dimensional point cloud, the data information of control system is obtained according to fuzzy set and fuzzy rule reasoning, Gigabit Ethernet is initialized, the data is transmitted through UDP user data protocol package, and the research on three-dimensional laser scanning data transmission system of liquefied gas railway tank car based on fuzzy algorithm is completed. The experimental results show that the designed system can effectively reduce the packet loss rate, the highest packet loss rate is only 22%, which makes up for the shortcomings of the traditional system, and is more suitable for the three-dimensional laser scanning data transmission of liquefied gas railway tank car.
