Model for calculating the reliability of a wireless sensor telecommunication system for monitoring the gas transmission network state

The paper presents the analysis results of the main causes of emergency situations on main gas pipelines and the state of the monitoring problem of their technical condition. Possible ways to solving this problem with the use of modern telecommunication facilities are also proposed. The paper proposes a model for calculating the reliability of a wireless sensor telecommunication system for monitoring the gas transmission network state, allowing the performance of the required probability level of failure-free operation when a certain number of wireless sensor modules fail. The reliability calculation of the system includes two stages: the module reliability and the reliability of the radio channel for transmitting information. The application technique for the Monte Carlo simulation method calculation is described. Since nowadays there are no known unified means for designing and building wireless STS, the paper proposes the main process stages of designing wireless sensor telecommunication networks using a well-known mathematical apparatus. The choice of the system dynamic type as the basis for further consideration in solving the specific task above is also substantiated.
