Abstract In order to solve the problem of empty-heavy mixing loading matching and measurement difficulty of container trucks in railway freight yards, the method of weighing sensor combined with Beidou high-precision positioning was studied. The results showed that when two 20-inch containers were loaded in the same freight train, the operation status of the container was judged by the rising and falling edges, and the location was fitted according to the speed when the container was lost. Finally, the landing distance of two containers on one truck was about 6000 mm, which was consistent with the length of the outer diameter of the 20-inch container. Torque balancing calculation was carried out on eight force points of the two containers, and the off-load bias state of the two containers was transformed into the whole vehicle metering state. The average error of the total weight was 0.4%, the average error of the X-direction bias was 0.3t, and the average error of the Y-direction offset was 3.46mm.
