With the rapid development of mobile Internet technology and the advent of the 21st century Internet and information age, data has become the most important strategic core resources. With the rapid development of ubiquitous power Internet of things construction, there are still many problems in the data link monitoring and data management: the low effectiveness of data transmission affects the normal operation of the data link; there are few data evaluation models, which lead to the problem of one sidedness and subjectivity in the understanding of the operation status of the data link. Aiming at the problem that the current data link cannot directly show the link quality, this position proposes a comprehensive evaluation method for the entire data link based on the order relationship analysis(G1) method and the entropy weight method. First, establish a complete data link indicator system, and then separately Use the order relationship analysis method to determine the subjective weight, use the entropy weight method to determine the objective weight, and finally combine the two to determine the comprehensive weight, and obtain a comprehensive score that reflects both the expert level and experience and the actual situation related data. The data and transmission conditions of each link are shown, and the comprehensiveness, rationality and scientificity of the method are also demonstrated.
