INTRODUCTION
EMERGENCY work is construction repair work that must
be completed as quickly as possible because the safety
of people or buildings are being threatened by emergency
circumstances, failures of public facilities, or road collapses or
closures due to uncontrollable natural forces or accidents. The
machines and tools used in emergency work, such as jackhammers,
dozers, and piling machines, always generate significant
vibrations and noise during operation, which can negatively
impact the surrounding environment and may even pose a
hazard to public health and safety [1]–[3].
RELATED WORKS AND DESIGN GOALS
Here, we discuss related works. The sensor products commercially
available today are either wire connected [6], [7]
or direct wireless communicate [8], [9] with receivers, which
suffer from the high cost of laying cable and poor wireless
communication quality. In order to take advantage of the benefit
of wireless technology without comprising communication
performance, it is crucial to design an appropriate multihop
wireless protocol for this application. Therefore, this section
discusses the related wireless network solutions that could
potentially be used in our pollution-monitoring system.
PERFORMANCE EVALUATION AND DISCUSSION
The initial results of this evaluation showed that the network
topology correctly formed and the data collected by the Tubes
could be delivered to the BS successfully. Since the collected
data (the statistics of the noise and vibration pollution) resulted
from particular events in the field (i.e., using a dozer, a piling
machine, or a driller), the occurrences could be verified using
images from the CCD camera or people. However, these
events could not reflect to the capability of the data delivery
performance of our system; thus, we focus on verifying the
communication performance of this system in the following
evaluation.
CONCLUSION AND FUTURE WORKS
In this paper, we present the design and implementation
of a distributed wireless sensor platform for measuring noise
pollution emitted during emergency work. Its key feature is
its wireless sensors, i.e., the Tubes, which can be easily and
quickly deployed on emergency work sites. The installation
of the Tubes does not require the user to consider issues of
communication because the Tubes construct a multihop communication
network automatically.We described the design and
related issues, including the hardware design of the Tube and
the sensing modules, the hardware packaging, and an integrated
communication protocol providing energy-saving and automatic
routing communication.
