Research purposes: At present high-speed railway ballastless track construction mainly uses artificial operation means in China, and it is difficult to meet the needs of intelligence and high quality development. The traditional track slab fine adjustment is realized based on industrial notebook computer, which is lack of portability and endurance, and the construction operation is not flexible. In order to realize the digitization and informatization of the track slab fine adjustment operation and improve the construction efficiency and laying accuracy of ballastless track, the track slab fine adjustment system is developed based on mobile terminal and wireless transmission mode. Research conclusions: (1) The system is developed based on the mobile terminal and Android platform, uses GeoCom communication technology to open up the control interface with the measuring robot, and realizes wireless communication and automatic control with the measuring robot. (2) The data interface with construction board software is opened, realizes the automatic calculation of fine adjustment deviation, and completes the wireless upload of fine adjustment results to the track slab fine adjustment information platform. (3) The software realizes the fine adjustment of track slab under wireless control mode, effectively improves the measurement efficiency and ensures the fine adjustment quality of ballastless track slab. (4) The research results can provide digital equipment for the construction of ballastless track of high-speed railway, and provide technical support for the construction of intelligent railway.
