The main requirements to diagnostics of structures in operation were formulated. Obtaining the information which should be provided by monitoring systems after processing of initially received data, is considered step by step. It is shown that the system of continuous monitoring of structures developed together with Hungarian specialists, allows evaluation and prediction of the structure state, both during short-term testing and in operation. The system is capable of solving practically all the main questions, related to ensuring the operational safety of structures. 18 Ref., 9 Fig. 12
