Fluorescent quantitative PCR instrument

The invention provides a fluorescent quantitative PCR instrument, and relates to the field of detection instruments, the fluorescent quantitative PCR instrument is composed of an upper computer and a lower computer, in the upper computer, a man-machine interaction interface is provided through a touch screen, and stable output power is provided through a power supply; the lower computer comprises a device shell, an uncovering detection module, a test tube detection module, a temperature control module, a fluorescence acquisition module, a driving module and an execution module, and an air duct operation mode that the rear top blows air inwards and the bottom draws air outwards is realized through a top fan, an air duct plate and a bottom fan; the cover opening detection module and the test tube detection module are used for respectively judging whether a cover is opened or a test tube is placed, so that automatic detection is realized, and the instrument is small in size, low in cost, simple in structure, sim
