The invention relates to a homogeneous immunoassay kit for detecting a target IgM antibody in a sample, its use method and application. The kit includes reagent a, which includes a known antigen, which can specifically bind to the target IgM antibody in the sample to be tested to form a first complex; reagent b, which includes complement C1q, and the complement C1q can specifically binding to the first complex to form a second complex, and the complement C1q cannot bind to free IgM antibodies; wherein, any one of the known antigen and complement C1q is connected to a receptor; The acceptor can react with the received singlet oxygen to generate a detectable chemiluminescent signal; the reagent c includes a donor, and the donor can generate singlet oxygen in an excited state. The method for detecting the target IgM antibody in the sample by using the above-mentioned kit solves the impact of the non-specific IgM antibody on the detection.

The present invention provides an active photovoltaic string arc fault detection method and system, including: active signal injection step: actively generate high-frequency signal, and actively output high-frequency signal on the photovoltaic string side; current signal collection step: in the photovoltaic string Measure and record the current signal on the DC bus on the string side to obtain the current signal information on the DC bus on the PV string side; arc fault judgment steps: perform wavelet transform processing and analyze the wavelet transform processing according to the current signal information on the DC bus on the PV string side After the signal characteristics, the wavelet transform processed signal characteristics are compared with the input high-frequency signal to determine whether an arc fault has occurred in the photovoltaic string, and obtain the active photovoltaic string arc fault detection result information. The invention performs detection on the side of the photovoltaic group string, and fundamentally solves the influence of inverter noise and different operating conditions on the detection.

The invention relates to an event detection oriented multi-strategy media data stream filtering method and a device thereof. The method comprises the following steps: in an offline stage, according tothe collected media user data, a garbage user database and an application source blacklist list are constructed; in the online identification stage, media data are filtered through the trash user database and the application source blacklist list, and non-event media data are filtered through the media content and context characteristics, and the media data are online clustered to identify the event clusters, and the media data in the event clusters are purified.
