For the operational applicability evaluation of telemetry system, the evaluation architecture based on comprehensive empowerment and cloud model is constructed. Using AHP, improve the coefficient of variation method and minimum identification information thought establish index comprehensive weight; using the cloud model theory, the "golden segmentation method" standard cloud design and similarity matching, determine the index level difference, find the equipment operational applicability weaknesses, telemetry system upgrade innovation and new equipment (software defined telemetry system) development basis to follow. Use the method for telemetry system operational efficiency, system adaptability, adaptability in service similar assessment provide reference, constantly improve the equipment complex environment adaptability.
