The invention discloses a radio and television backbone network transmission system health state evaluation method, which comprises the following steps of: a, establishing an evaluation model based on an analytic hierarchy process, constructing a triangular fuzzy judgment matrix, calculating a fuzzy comprehensive value according to the triangular fuzzy judgment matrix, and establishing a comprehensive value matrix according to the fuzzy comprehensive value; b, performing triple authentication on the comprehensive value matrix to calculate a local weight and a global weight; c, calculating the degradation degree and the health degree according to the operation numerical value of the broadcast and television backbone network transmission system; and d, according to the local weight, the global weight, the deterioration degree and the health degree, calculating to obtain a health state evaluation value of the broadcast and TV backbone network transmission system. The method can be suitable for health state evaluation of the broadcast and TV backbone network transmission system, and has the advantages of scientific, rigorous and accurate evaluation.
Description
technical field [0001] The invention relates to the technical field of radio and television, in particular to a method for evaluating the health state of a transmission system of a radio and television backbone network. Background technique [0002] With the continuous growth of services such as the centralized processing of radio and television signal services, the scheduling of news and live broadcast signals, and the distribution of services in cities, counties, and districts, Zhejiang Province's radio and television backbone network transmission system is facing increasing pressure for safe broadcasting, including continuous Increased reliability requirements, high system and equipment complexity, and coexistence of new and old systems. A complete transmission system needs to rely on reliable transmission equipment, safe optical cable routing and professional maintenance technology to achieve the requirements of the State Administration of Radio, Film and Television for ...
