Abstract

The invention relates to the technical field of vacuum environment control, and discloses a pipe tunnel vacuum control method and system. The method comprises the following steps: S100, collecting the vacuum degree of the separated part of two vacuum pipelines in real time; s102, whether the current vacuum degree is within a preset range or not is judged, if yes, the step S104 is executed, and if not, the process is ended; s104, a first vacuum pump is controlled to be started to execute vacuum pumping operation, and a second vacuum pump is controlled to be started to execute vacuum pumping operation after a preset time interval; s106, whether the current vacuum degree is smaller than or equal to the target vacuum degree or not is judged, if yes, the step S112 is executed, and if not, the step S108 is executed; s108, whether the current vacuum degree is smaller than or equal to the preset vacuum degree or not is judged, if yes, the step S110 is executed, and if not, the step S106 is executed; s110, a third vacuum pump is controlled to be started to execute vacuumizing operation, and the step S106 is executed again; s112, judging whether a third vacuum pump is in an open state or not, if yes, turning to S114, and if not, turning to S116; s114, controlling the third vacuum pump to be closed, and turning to S116; and S116, the second vacuum pump is controlled to be closed.

Description

technical field [0001] The invention relates to the technical field of vacuum environment control, in particular to a tube tunnel vacuum control method and system. Background technique [0002] The vacuum pipeline is the infrastructure for the operation of the maglev high-speed flying car with a speed of 1000km / h. The vacuum pipeline mainly includes the pipe beam structure, the basic support and the vacuum equipment system. The tube-beam structure is the main structure of the vacuum test bench, providing a container carrier with sufficient strength and excellent sealing performance; the basic support provides a load bearing for the container installation and controllable settlement; the vacuum equipment system includes a vacuum pump set, a re-pressure valve, and power supply equipment , its function is to provide functional equipment for the test platform to establish a vacuum, restore the atmosphere, and supply power to the vacuum environment. [0003] Due to the need to s...
