LABVIEW BASED WIRELESS SENSOR FOR MONITORING THE BUILDING

An advanced simulation on LABVIEW software is provides an effective solution for building monitoring takes advantage of the unique features of custom-developed MEMS sensors and read-out ASIC combined with an optimized network and module architecture, to realize a solution which offers long battery lifetime and potentially low cost in manufacturing, installation and maintenance, while providing high-quality sensor data at the right time which can be proposed for monitoring building to assess earthquake damage. Low power network architecture was implemented over an 802.15.4 MAC in the 900-MHz band. A custom patch antenna was designed in this frequency band to obtain robust links in real-world conditions. The modules have been validated in a full-scale laboratory setup with simulated earthquakes. This will be illustrated via LABVIEW software which shows the Temperature level in the time of Earthquake and which helps in preventing the human life.

ABSTRACT

Due to the Natural calamity, Material aging, Design error the buildings can get damage during their lifetime……….

To eradicate this problem…….

LABVIEW

Laboratory Virtual Instrumentation Engineering Workbench

Two types of sensor modules have been developed in the monitoring system…

Strain sensing modulesAcceleration sensing modules

• They are placed in the building as the lowest level of the building the strain sensor modules are mounted for the estimating the vertical column loads and to measure the settlement and the plastic hinge activation of the building after an earthquake.

• Horizontal acceleration is measured by two 3D acceleration sensing modules (where only the two horizontal axes are really required) at each level during an earthquake, allowing analysis of the seismic response of the whole structure

Wireless sensors are easy to install, remove, and replace at any location, and are expected to become increasingly smaller (“smart dust”) by using MEMS technology.

The acceleration and strain at numerous locations on each beam and column, temperature and light in each room, images and sounds in desired regions can be obtained by the “smart dust” sensors, as illustrated in.

Additionally, a single type of sensor such as a condenser microphone can be used for multiple purposes, for example, to detect earthquake, fires and intrusions. Furthermore, a fiber optic network is not only utilized as infrastructure for information technology, but also as a “wired” sensor network.

For installing these components in the building which will be placed into a standard off-the-shelf plastic casing that can be conveniently mounted on the floor, wall or ceiling using screws, and offering access for sporadic battery replacement if needed.

Thank You……….!!!
