An Effective Fault Diagnosis Strategy of Test Point Optimization for Communication Radio Station

For the problems of test diagnosis for communication radio stations,a method based on GADPSO and rule of maximum diagnosis information is presented to solve the fault diagnosis of communication radio stations by optimizing the test point＇s fault-test matrix. As the genetic operator is introduced into the DPSO, the algorithm is used to find the optimum test points. By adopting maximum fault diagnosis information, test order can be selected based on the information. The result shows that the GADPSO has better computation efficiency and precision. The GADPSO not only avoids the local optimization and premature convergence,but also improves the searching efficiency. Rule of maximum diagnosis information can estimate test points and is fast and effective in finding the test order. It offers an efficient method for the fault diagnosis strategy of communication radio station.
