• an extraction strip, an extraction-strip loading device which has a function of on-line adding the extraction strip and is configured to load the extraction strip, a sample-holder loading device which is configured to load and unload a sample, an extraction-strip transfer gripper which is configured to drive the extraction strip to move to a preset position, a nucleic-acid extraction device which is configured to refine the sample to obtain nucleic acid, a PCR test device which is configured to perform a fluorescent PCR test on the nucleic acid, and a control device;
• wherein the extraction-strip loading device, the sample-holder loading device, the extraction-strip transfer gripper, the nucleic-acid extraction device and the PCR test device are connected to the control device,
• wherein the PCR test device comprises a fluorescent PCR test device which is configured to perform fluorescent PCR tests on a sealed PCR tube;
• and
• the fluorescent PCR test device is connected to the control device,
• wherein the fluorescent PCR test device comprises:
• a housing, a photometry assembly and temperature control components, wherein the housing is provided with a plurality of test positions for placing the sealed PCR, and each of the plurality of test positions is provided with the corresponding temperature control component, so that the temperatures in the plurality of test positions are independently controlled to rise or fall;
• wherein the photometry assembly and the temperature control components are both connected to the control device;
• and
• the photometry assembly comprises a light source assembly which is configured to provide a test light source and a driving component which is configured to drive the light source assembly to move;
• the number of the light source assembly is plural, the plurality of light source assemblies provide different types of light sources, and each light source assembly illuminates, driven by the driving component, the corresponding test position.
