Abstract
The goal of this article is to solve problems of automated monitoring systems of industrial and aviation constructions. Based on the latest research results, the most cost-effective solutions are covered, and a practical solution is offered. This article is part of the scientific project “Development of an integrated sensor system for material and structure monitoring”. The article describes the problem and suggests a practical solution for an integrated sensor system for material and structure monitoring prototype.
Highlights
Monitoring of constructions is made “all the time”, that is to say - any interval deemed necessary; from the point of view of statistics - when the variable “chance the construction would crash” meets the variable “this much money can be spent on inspection”
The most commonly used simple EMI system is based on an impedance converter, see Fig. 1, as the AD5933 1 MSPS, a 12Bit converter and its evaluation hardware EVAL-AD5933EBZ
Though the Orange Pi solution requires some manual modification to adjust it to the power over ethernet (POE) requirements, this modification provides the system with flexibility not found in the default configuration of any other stock computing solution due to ability to provide higher or lower POE voltages, while the Onion Omega has RJ45 by default, allowing easier installation, though provide only default voltage values
Summary
Monitoring of constructions is made “all the time”, that is to say - any interval deemed necessary; from the point of view of statistics - when the variable “chance the construction would crash” meets the variable “this much money can be spent on inspection”. Manufacturing plants stop, trains break and even derail, bridges crumble and collapse, aircrafts fail and even crash. To make such occurrences less often and less severe, automated monitoring systems should be introduced. Systems that would really be able to monitor all the time - constantly and without any intervals; this would let us know when the first sign of a budding problem occurs instead of how it has to be done immediately - the best that can be done with manual maintenance at intervals - if luck allows it, to find actual problems that have already appeared or even clustered together, forming a bigger problem [1],[2],[4]-[6] Inventing and II. Maris Hauka et al Automated sensory monitoring system prototype for continuous monitoring of material and structure state the suggested frequency range for concrete construction depending on the depth of the scan required [8]
