Building vacuum toilet control method and system

The invention discloses a building vacuum toilet control method and system. According to the technical scheme, the building vacuum toilet control method comprises the steps that operation information, blockage fault information and leakage fault information of each vacuum toilet are obtained; the operation information of each vacuum toilet is identified and processed, whether each vacuum toilet is in a use or idle state is judged, and a vacuum pump station is controlled to be in an operation or standby state according to the use or idle state of each vacuum toilet; the fault information of the vacuum toilets is identified and processed, and when a blockage or leakage fault occurs, the vacuum toilets send out alarm information, and the blockage or leakage fault information and the fault position are displayed; when a leakage fault occurs, the vacuum pump station stops running; and the blockage or leakage fault of the vacuum toilets is handled, then the fault is reset, and the operation of the vacuum pump stati
