Introduction
Contenido
La civiónica es la combinación de distintas disciplinas dentro del mundo ingenieril, es una mezcla de la ingeniería civil con la ingeniería eléctrica, ingeniería mecatrónica, ingeniería física, ingeniería en sistemas, etc. Esta disciplina engloba distintas actividades que van relacionadas con temas de la construcción; por ejemplo:[1] sistema de monitoreo de la salud de un edificio, escanometría con drones y sensores láser, estudios de daño, pruebas no destructivas (ultrasonido, emisiones acústicas, corrientes de Eddy, líquidos penetrantes,entre otros).
Building health monitoring system
Building health monitoring systems are structures that are equipped with different types of sensors that fulfill different functionalities when studying a building.[2] When modeling, designing and constructing a building, a design criterion is considered by which its behavior will govern. To check that it works properly, different sensors can be installed to verify that the structural system works as planned.
Extensometers are devices sensitive to the deformations suffered by a structural element. These sensors are used in members that suffer a significant load and we want to know if the deformations of these elements. When a load is carried out, it is verified whether they behave with the deformations that they should have according to a digital model or the design criteria that was used when it was built. The way of reading is through microdeformations µΣ.
Inclinometers are sensors capable of detecting the smallest changes in degrees that occur in a structural member.[3] These devices are used to detect if there is movement in a direction and how much it is tilting. The reading of this device is in degrees.
Accelerometers are sensors capable of measuring the linear and angular acceleration of an element.[4] These are used in civil engineering to measure the natural vibrations of a system and how they behave under different loads. They can also be used to verify the behavior of a building when carrying out a load test on the structure. The reading from this device is a frequency of the speed change with respect to time.
Displacement sensors "Displacement (vector)") measure the distance that an element moves with respect to a referenced position with millimeter accuracy,[5] they are useful in civil engineering to verify how much is displaced or deformed (buckling towards a certain direction) within a structural element. The reading of this device is in millimeters.
