The invention discloses a start-stop control system for a vacuum metal pipeline high-speed train. The start-stop control system comprises laser emitters, laser receivers and a power system, the laseremitters are mounted in a metal pipeline at equal intervals, and the laser receivers are mounted on the high-speed train. A position reference is determined through the laser transmitters, and ideal time for reaching each position is calculated in advance. The laser receivers are used for recording the time when the high-speed train passes through each laser emitter so as to determine the speed and the acceleration of the high-speed train, and the high-speed train adjusts a power system of the high-speed train according to the difference value between the ideal time and the actual time when the high-speed train reaches each position. The PID control principle is adopted, the ideal time for the high-speed train to pass through the fixed position in the vacuum metal pipeline is compared withthe actual time, the running speed of the high-speed train is controlled and adjusted, and the comfort and safety of passengers on the train are guaranteed; and the speed of the train is acceleratedto thousands of kilometers per hour or decelerated to be static from thousands of kilometers per hour as soon as possible.
