Abstract
A time-division multiplexing control device applied to a distributed X-ray source includes: a first switch module with a number of first switches that receive a high-voltage signal and a first control signal, selectively turning on one of the plurality of first switches according to the first control signal and sending the high-voltage signal through the first switch turned on; and a cathode control module including a plurality of cathode control stages in one-to-one correspondence with the plurality of first switches, used for receiving the high-voltage signal from the first switch module and sending working state data through a cathode control stage corresponding to the first switch turned on in the plurality of cathode control stages, where each cathode control stage includes a cathode control unit and a cathode.
