Detecting and sampling system and detecting and sampling method

The invention discloses a detecting and sampling system and a detecting and sampling method. The system is used for sampling and detecting specifications of products; the products flow through a preset cavity of a preset process condition; a first comparing unit of the system is used for respectively comparing a current count value of each counter with a warning value corresponding to the counter, so as to obtain a first comparing result; a second comparing unit is used for respectively comparing the current count value of each counter with an upper limit value corresponding to the counter, so as to obtain a second comparing result; a sampling unit is used for sampling the products flowing through the preset cavity according to the preset sampling strategy; a processing unit is used for controlling the sampling unit according to the comparing results. According to the detecting and sampling system and the detecting and sampling method, the products flowing through the preset cavity of the preset process condition are counted by virtue of the counter; intelligent judgment is achieved through the first comparing unit and the second comparing unit; the specifications of the products flowing through the corresponding preset cavity are sampled and detected according to the judgment result, so that the sampling uniformity of the specifications of the products is improved.
