- Zigbee
wireless sensor network for better interactive industrial Automation
This
paper deals with the design of a Modbus Enabled Zigbee Wireless Sensor Network
“WSN” for better Interactive Industrial Automation. The Modbus protocol is
embedded into Zigbee stack, providing a friendly interface to observe the information
in the wireless network efficiently and to provide the On Demand Response to
the requests. It consists of a Coordinator and the sensor nodes. The
coordinator is a centralized unit which is attached to the monitoring PC. It collects
the information from all other nodes on demand and provides to the end user
through TCP/IP network. The sensor nodes are made intelligent for controlling
the plant. These nodes are attached with the Zigbee for remote controlling in
case of changing the preset values and handling any issues. The coordinator is
implemented using the ARM9 controller and the Sensor Nodes are implemented
using the ARM7 microcontroller. RTLinux is used at the coordinator for real
time operations and the Sensor nodes are programmed using the Embedded C. The
experimental results obtained demonstrate the usefulness of the proposed system
in terms of the low power consumption, low cost, targeted towards automation
and remote control applications.
- Attitude
estimation and control of a quadrocopter
The research interest in unmanned
aerial vehicles (UAV) has grown rapidly over the past decade. UAV applications
range from purely scientific over
civil to military. Technical advances in sensor and signal processing technologies
enable the design of light weight and economic airborne platforms. This paper
presents a complete mechatronic design process of a quadrotor UAV, including
mechanical design, modeling of quadrotor and actuator dynamics and attitude
stabilization control. Robust attitude estimation is achieved by fusion of
lowcost MEMS accelerometer and gyroscope signals with a Kalman filter.
Experiments with a gimbal mounted quadrotor testbed allow a quantitative
analysis and comparision of the PID and Integral-Backstepping (IB) controller
design for attitude stabilization
with respect to reference signal
tracking,disturbance rejection and robustness.
- Full
Control of a Quadcopter
The research on autonomous
miniature flying robots has intensified considerably thanks to the recent
growth
of civil and military interest in
Unmanned Aerial Vehicles (UAV). This paper summarizes the final results of the
modeling and control parts of OS4 project, which focused on design and control
of a quadrotor. It introduces a simulation model which takes into account the
variation of the aerodynamical coefficients due to vehicle motion. The control
parameters found with this model are successfully used on the helicopter
without re-tuning. The last part of this paper describes the control approach
(Integral Backstepping) and the scheme we propose for full control of
quadrotors (attitude, altitude and position). Finally, the results of
autonomous take-off, hover, landing and
collision avoidance are
presented.
- Development
of an UAV for Search & Rescue Applications
In the
event of a disaster, there is an impending need for robotic assistance in order
to conduct an effective search and rescue operation, due to their immediate
permissible deployment. In this paper, the development of an unmanned aerial
vehicle (UAV) intended for search and rescue applications is presented. The
platform for the UAV is a quad-rotor type helicopter, simply referred to as a
quadrotor. A plan for the mechatronic system integration was devised to combine
the mechanical, electronic and software elements of the research. Once the
system was modelled mathematically, a control strategy was implemented to achieve
stability. This was investigated by creating a MATLAB® Simulink® numerical
model, which was used to run simulations of the system.

- Remote
management and control system for LED based plant factory using ZigBee and
Internet
Recently, intelligent systems for agricultural production are being
developed for safe and low cost food production. Plant factory provide high
yield by growing multiple crops and making efficient use of land and resources.
Plant growth is facilitated by maintaining humidity, temperature, CO2 concentration
and light intensity and these factors need to be monitored and maintained for
an automated system. In this paper, we have proposed a control system for a LED
based plant factory consisting of ZigBee wireless mesh network, and
remote monitoring via Internet. Field sensors are installed for monitoring
environmental conditions and power metering and ZigBee mesh network
has been deployed for data acquisition from these sensors. ZigBee nodes
transfer the field data to the coordinator node which also serves as a gateway
node providing interoperability between TCP/IP network and ZigBee Wireless
Sensor Network (WSN). A major novelty of the system is the use of LED lighting
instead of fluorescent lighting due to its low power consumption, long life and
useful narrow band. LED lighting system provides an efficient and economical
lighting system that facilitates plant growth by varying light intensity and
frequency according to light conditions and growing requirements and also helps
in reducing production costs and speeding growth. Prototype of the proposed
system has been installed in a small part of greenhouse. Data acquisition and
remote management of the system has shown very satisfactory performance.
- A Reliable
Transmission Protocol for ZigBee-Based Wireless Patient Monitoring
Patient monitoring systems are gaining their
importance as the fast-growing global elderly population increases demands for
caretaking. These systems use wireless technologies to transmit vital signs for
medical evaluation. In a multihop ZigBee network, the existing
systems usually use broadcast or multicast schemes to increase the reliability
of signals transmission; however, both the schemes lead to significantly higher
network traffic and end-to-end transmission delay. In this paper, we present a
reliable transmission protocol based on anycast routing for wireless patient
monitoring. Our scheme automatically selects the closest data receiver in an
anycast group as a destination to reduce the transmission latency as well as
the
control overhead. The new protocol also shortens the latency of path recovery by
initiating route recovery from the intermediate routers of the original path.
On the basis of a reliable transmission scheme, we implement a ZigBee device
for fall monitoring, which integrates fall detection, indoor positioning, and
ECG monitoring. When the triaxial accelerometer of the device detects a fall,
the current position of the patient is transmitted to an emergency center through
a ZigBee network. In order to clarify the situation of the fallen
patient, 4-s ECG signals are also transmitted. Our transmission scheme ensures
the successful transmission of these critical messages. The experimental
results show that our scheme is fast and reliable. We also demonstrate that our
devices can seamlessly integrate with the next generation technology of
wireless wide area network, worldwide interoperability for microwave access, to
achieve real-time patient monitoring.
