Method and device for detecting flowing liquid based on micro-fluidic chip

The invention provides a method and a device for detecting flowing liquid based on a micro-fluidic chip, the method and the device are applied to a system comprising upper computer software, a rotating system, a photoelectric switch and a high-speed camera, the upper computer software controls the rotation of the rotating system, the rotating system controls the opening and closing of the photoelectric switch, and the high-speed camera is connected with the photoelectric switch. The photoelectric switch can transmit a signal to the high-speed camera, and the image acquisition method comprises the following steps: step 1, writing step information by adopting upper computer software to set motion data of the rotating system, and transmitting the data to the rotating system through USB communication; 2, the rotating system receives the motion data and rotates according to the set data; 3, after the rotating system rotates by one circle, the photoelectric switch is triggered once, and the photoelectric switch can
