The invention discloses a cabin cloth product disinfection detection method and system adaptive to multiple cabin standards, belongs to the technical field of cabin cleaning, and is used for solving the technical problems that an existing cabin cloth product disinfection detection method is long in detection period, single in detection means, poor in universality and incapable of meeting health service requirements. The method comprises the following steps: establishing a multi-cabin standard detection model, and initializing parameters; collecting a surface electrical response signal of the target cloth product through the dual-sensor detection terminal, and reading a cabin type to which the target cloth product belongs; performing filtering denoising and feature extraction on the surface electrical response signal to obtain a standardized feature value; inputting the cabin type and the standardized characteristic value into a multi-cabin standard detection model to obtain an actual index value and a disinfection effect comprehensive judgment value; if the comprehensive judgment value of the disinfection effect does not reach the standard, the disinfection parameters of the disinfection equipment are optimized according to the cabin type, and secondary disinfection and re-detection are conducted on the target cloth product.

The invention discloses a totally-enclosed avian influenza H5, H7, H9 and universal virus quadruple detection kit. The kit comprises primers and probes of a universal avian influenza virus M gene, an H5 subtype avian influenza virus HA gene, an H7 subtype avian influenza virus HA gene, an H9 subtype avian influenza virus HA gene and a reference gene LconR. According to the invention, the ligand-dependent nuclear receptor corepressor protein is introduced as a reference gene, and the gene widely exists in mammals and birds and is very suitable for detection of multi-species infection epidemic diseases such as avian influenza. The internal reference can participate in nucleic acid extraction and amplification processes, strictly controls the quality of each detection step, fundamentally avoids false negative results, and significantly improves the reliability of detection results. The internal reference also expands the species application range of the detection method, so that avian influenza detection is not limited to poultry any more, and the method can be widely applied to all mammals possibly infected with avian influenza.
