Durability Evaluation of a Distributed Communication Network of Weather Stations

We consider the problem of ensuring the durability indicators of a distributed communication automatic weather stations network (AWSN), consisting of access points and weather stations (WS), remote from each other at distances of up to several tens of kilometers and connected to the nearest access points and to each other by communication channels. An expert assessment of the durability indicators was carried out and the modes of operation of the distributed AWSN were determined. A model of the complex load factor and resource of the distributed AWSN has been elaborated. A method for assessing and a methodology for determining the durability indicators of AWSN has been developed, which, based on the initial data for AWSN elements, the operating model of the elements and the calculated values of the complex load factor for each of the modes, calculates the gamma-percentage resource before the decommissioning of the AWSN element, based on the criterion of the limit state of the AWSN. The modeling and calculation of durability indicators of the distributed AWSN have been carried out according to the proposed method. © 2021, Springer Nature Switzerland AG.
