The invention provides an identification method for an agglutination test, which belongs to the technical field of medical detection methods. The recognition method converts the agglutination test result into digital graphic information through a camera or video camera, and then recognizes the result level of the agglutination test through computer image processing. This method can effectively reduce the error rate caused by human subjective recognition test results.

The invention belongs to the field of information exchange of relay protection devices in power systems, and in particular relates to an information interaction method between devices oriented to area protection based on communication. Through modeling and data processing for the information required by the communication-based protection function, the processed state flow information is generated from the relay protection sampling value information with a large amount of transmitted data, reducing the amount of information interaction between devices and meeting the requirements of the protection communication function. Network performance requirements; through the construction of the information communication architecture of the device and the communication architecture of the regional protection system, the regional sampling value information acquisition and intra-area status flow information interaction functions between protection devices in the regional power grid are formed. The invention effectively solves the contradiction between information interaction between relay protection devices and network transmission performance, and provides a necessary communication function basis for the realization of a communication-based relay protection system.
