The invention provides a multi-channel microdroplet detection method and device and a detection chip switching system. The detection method comprises the following steps: acquiring a to-be-detected sample set; sucking each sample to be detected into a liquid path detection system one by one; whenever it is detected that one to-be-detected sample is sucked into the first liquid path detection unit, the first sample injection needle is controlled to suck the next to-be-detected sample and input the next to-be-detected sample into the second liquid path detection unit, so that the next to-be-detected sample enters a detection waiting stage; when it is detected that one liquid path detection unit is in the detection stage, a detection chip in the liquid path detection unit is switched to a detection station; all the liquid path detection units jointly use the detection station to carry out fluorescence detection on the sucked sample to be detected. According to the method, by adjusting the time sequence of the de
