Monitorización de cubiertas atirantadas = Monitoring covered straining

The implementation of an adequate system of stress control of the suspenders in covered straining is essential to preserve the correct functioning of the same over time. Taking as an example the cover of the coal park of As Pontes Thermal Power Station, four case studies are analyzed: Theoretical model, indirect model of vibrating string, weighing model with cat and model with permanent monitoring system. In order to validate the installed monitoring system, a results comparison is made based on the analysis of the four models. From this analysis we can conclude that not only is the system more approximate to the expected results of the theoretical model, but its functional advantages lead to recommend its application in a generalized way. The installed system is based on the placement of load cells of strain gauges and the implementation of a wireless data acquisition system. An innovative technological improvement is carried out consisting in the placement of a transmitters of remote communication and in the development of an Android application that allows the direct access to the readings and the configuration of the system.
