Time-sharing cooperative excitation control system

The invention discloses a time-sharing cooperative excitation control system, which is characterized in that a GPS Beidou satellite is wirelessly connected with a GPS signal receiving end of a GPS/BD time service device, a signal output end of a single GPS/BD time service device is connected with a GPS signal input end of a single corresponding controller, time reference lines of a plurality of controllers are synchronized by receiving a clock in the GPS Beidou satellite, and the time reference lines are connected with the GPS signal receiving end of the GPS/BD time service device. A time slice processing module is arranged in the controller; the FO signal output end of the 428XL seismic instrument is connected with the digital signal processing module through an FO signal general I/O port of the controller, the digital signal processing module is connected with the time slice processing module, and the time slice processing module is connected with the BOOMBOX encoder through the FO signal output end of the
