MODULE –5: Data Receiving, Sorting and organising
Simultaneous accumulation of data is achieved by scheduling the events. Normal periodic data is collected as a routine. However, there are instances where data is generated upon an event. For instance, if an overloaded truck is passing over a bridge it can trigger a set of data, this in turn activates the communication receiving mode at the command center and data is instantaneously received. The data thus generated is a real-time data. However, the transfer of data may or may not be real-time depending upon the location of the infrastructure and the remote accessibility of the infrastructure. Multiple channels can operate at the command center to receive data as per the schedule. The size of the receiving module could match the volume of data generated in the given region.
MODULE –6: Real Time Environmental Data
Accumulation of real-time environment data is done to get the actual environmental conditions at a particular location where the infrastructure is being monitored. The environmental factors which can influence the behavior of an infrastructure are , Wind velocity, Temperature, Flood level, Tidal wave, Storm intensity ,Earth quake intensity, etc .This data can be obtained periodically for the locations at which the infrastructure is being monitored. This data is mostly collected through weather monitoring satellites globally.
MODULE – 7: Mathematical Modeling
In this module, a mathematical model which is built based on the data available on the condition of an infrastructural unit, a bridge for instance. This is done using standard available Structural Engineering Packages. The mathematical model represents behavior of the actual structure it represents. Hence when this module is made to interact with the external influences like loads, weather conditions etc, it reflects on the behavior of the actual structure. Any standard Structural package serves good for this purpose of Mathematical Modeling.
ODULE – 8: Algorithm
This module is an engine which lets the mathematical model of the structure and the external influences interact. It is built based on the engineering principles
MODULE – 9 Analysis
An analysis is said to have been done when the mathematical model is made to interact with the external forces as per the defined algorithm. The resultants are tabulated or translated to graphic displays. Normally, extreme loads cause distortion in the proportions of a structure, leading to cracks and then an automate failure, if no attention is paid to the deviations from the designed parameters in a structure.
MODULE: 10: Graphic Display
At the Infrastructure Health Monitoring Command Center, a display can be made on a wall mounted screen. The initial display could reflect the geographic location of the infrastructure in the region. GIS and GPS can be used for this display. As already demonstrated by Myung-Hee Jo 5
Subsequently, all the analysis and the effects of the loads on each of this infrastructure can be displayed, when all the modules function. Hence, all the changes in a given structure are visible through interactive modules. This gives an instantaneous insight into a structure system, which otherwise is not visible in a physical inspection of the actual location.
This graphic package when integrated with structural engineering software can zoom in on a specific structure and highlight the mathematical model of the structure as required.
Conclusions
It can be said that it is possible for the developing and the under developed countries to adapt latest technological innovations. However, a word of caution here, adaptation of new technologies is a costly affair. Adapting any new technology in isolation will not be beneficial. Due consideration must be paid to using these technology in combination with other available technologies around. As can be seen here in Highway infrastructure monitoring technology, when applied in combination with some of the other compatible technologies, it not only becomes cost effective, but also the scope of its application can be broad.
