In today’s world, the infrastructure
provided by smart city and
industrial automation systems
enables continuous connectivity.
The commonality shared by such
systems is their association with
the Internet of Things (IoT). With
the inclusion of sensors and control
devices, entire infrastructures can
be integrated with information
and communication technologies,
resultinginnetworkedandembedded
devices that enable intelligent
monitoring and management. With
the easy deployment and flexibility
of sensor devices, wireless sensor
networks (WSN) can comprise
numerous sensor nodes that
collect information. The collected
information then provides a database
for further analysis; the results of
which can be used to improve the
reliability and efficiency of existing
infrastructure systems. Considering
the rapid development of sensor
technology, WSNs are expected to
become a key IoT technology.
Wireless I/O
Connectivity Modules
and Gateway Solution
For engineers, the greatest
challenge of designing for the IoT
is ensuring wireless connectivity.
The concept of the IoT involves
not only new devices designed with
IoT compatibility, but also existing
systems that operate outside the
IoT cloud. However, to establish a
ubiquitous cloud of interconnected
devices, non IP-based devices must
be able to connect to each other
without requiring Ethernet or a
Wi-Fi interface and accompanying
protocol stack. This can be achieved
using wireless I/O interface modules
and gateways that enable Internet
access in the context of real-world
applications. Furthermore, adding
intelligent sensor control software
to gateways can simplify the design
of IoT systems by providing access
to shared processing resources.
This
paper
addresses
the
implementation of IP connectivity,
security, disparate node aggregation,
device management, as well as a
software development kit (SDK)
that enables customization.
Considering the demands of potential
applications, Advantech’s WISE-
3000 gateways and WISE-1000
wireless I/O modules can satisfy
most customer requirements. Using
a WISE-100 wireless I/O module
and WISE-3000 gateway, system
integrators can easily connect
existing control devices and sensors
to IoT systems for data collection
and device control based on the
results of subsequent data analysis.
