Development of Remote Monitoring System For Civil Engineering

Remote monitoring system has gained entry into our everyday life. It is used in a wide range of applications like navigation system for vehicles, civil engineering, weather radar, transportation or traffic management, law enforcement and many more. All these applications depend up on the advancements in remote monitoring systems integrated with sensors. This post gives some information about development of remote monitoring system for civil engineering.


The latest advancements in smart equipments and structures sensors provide several exclusive prospects to analyze the structural integrity of civil structures. Nevertheless, the remote functional surroundings of huge civil structures like bridges, highways and buildings makes condition based health scrutinizing for damage evaluation complicated in case of natural calamities.

In case of natural tragedies, there is loss of power and heavy usage of mobile phone lines. This sets a boundary line for the recovery of significant sensor information. However, the recent developments in remote sensors have made it possible for safe retrieval of data economically. Thus, the smart sensors used in remote monitoring enable to supervise the health of huge civil structures remotely.

To be more specific about the above section, a remote monitoring system for civil buildings is designed by making use of normal strain sensors, ‘data transfer’ software and spread spectrum wireless modems. This organization is tested by monitoring the loads on a lab specimen with a bolted joint from a far distance, say one mile. Instructions are given from a laptop or personal computer to order the monitoring system to either obtain data from the externally mounted sensors on the structure or excite the structure. The collected data is then sent back to the computer through a wireless medium for analysis and processing. The analyzing is done by using damage detection algorithms.


Use of Opto-electronic Sensors For Remote Monitoring

Opto-electronic sensors are used in remote monitoring systems for measurements of strains, full field displacements, deformations, etc in civil engineering structures. These sensors are based on optical methods like grating, digital holography, interferometry, digital image correlation, fringe projection and fringe moiré. Due to the many kinds of sensors used, the monitoring system allows measuring diversity of engineering entities like objects with reflective surfaces, flat or non flat things, etc.


The universal methods, modular designs and scaling abilities used in the monitoring system enables to scrutinize a huge group of engineering structures like dams, bridges, highways, pipelines, buildings, etc.

The Bottom Line

There are many research projects going on to develop advanced sensors to be used in instrumentation of different kinds of infrastructure. Development of remote monitoring systems for civil engineering has created a huge difference in the projects with a range of exclusive benefits.
