ECM Interface: Schlumberger/Jim Mayes (Dr. Glover)



Diagnostic information used to ensure energy efficient and therefore
clean operation can be extracted from int
elligent controllers called
Engine Control Modules or ECMs found on current generation diesel
engines. This Project involves the development of a Diagnostic
Interface that will connect to and extract diagnostic information from
an engine driven pump via a
CAN interface. It is anticipated that an
actual Pump ECM will not be available for development and debug.
Therefore an OBDII emulator will be developed. In the event an
Engine Control Module is not available, the OBDII interface in a car
will be used to au
gment software development as well as for the final
test of the system

Mesh Radio Se
nsor Detection
.
This is a Digi XBEE
-
Pro 900 HP
wireless mesh radio application where a group of Remote sensors
communicate wirelessly with a Host. The primary purpose of this
project is to design a very low power, inexpensive, mesh
-
radio
Remote that can s
urvive and remain powered for 1
-
5 years. Unique
and innovative power management strategies must be explored. The
goal is 5 years of active, uninterrupted service of a rugged device that
when commercial can cost less than a few hundred dollars. The
autonomo
us life of the Remote is the most important aspect of this
project and it is anticipated that this requirement will determine
critical performance parameters of the system.

The objective of this project is to develop image processing
techniques to extract features from space

NASA Texas Space Grant Consortium Project

Aug.

, 2013

We have an opportunity to apply for projects with NASA through the Texas Space
Grant Consortium (TSGC) Design Challenge. These projects are devised by NASA,
and include technical experitse, and pos
sibly funding (though not a lot) from NASA.
UH ECE participated in the Design Challenge in Fall 2011 and won four awards at
the final conference presentation at NASA, including best poster and best
presentation, among other things. This was a great accompl
ishment since there were
teams from Rice and Texas Tech there as well! In other semesters A&M and UT also
participate.

So we have a reputation to uphold!

Check out the main site at

semester projects and others are
two

Instrumentation and Control of an MR Bypass Valve

Valves are critical components of control systems in the production of offshore oil &
gas. Valve actuation in offshore oil & gas is controlled by tradition
al hydraulic
methods. In traditional hydraulic control systems, the actuation of valves is delayed
due to very long hydraulic lines. These long hydraulic lines also need to carry high
pressure fluid at all times during normal operation. As a result traditi
onal control
systems cannot precisely control valves.

As a solution to the above mentioned problems, use of
MagnetoRheological (MR)

fluid to hold and control the load during valve actuation is proposed. When a
magnetic field is applied to MR fluids, the
yield shear stress of the MR fluids
increase, effectively solidifying the MR fluids below a certain stress level. This
instantaneous and controlled change in rheological properties of MR was the key
concept used to develop MR valves. An innovative MR bypas
s valve was designed
and developed as a proof of concept by a Mechanical Engineering (ME) senior design
team (2012
-
13) at Smart Materials and Structures Laboratory at University of
Houston. The ME senior design team (2012
-
13) and researchers in Dr. Song’s
research group have successfully developed a design and built a prototype for
demonstration. However, this prototype does not have any instrumentation nor
feedback controls.

MR Bypass Valve Prototype

Problem Statement:

The prototype of the MR bypass valve that was built by the ME senior design team is
shown in Figure 1. The electromagnets used in the project were not strong enough to
generate a magnetic field strong enough to adequately solidify the MR fluids. As a
resul
t, the MR valve was unable to stop fluid flow above 150psi pressure difference.
The pressure readings were taken by using two analog pressure gauges on the system
and the electromagnets were powered via a manually controlled DC power supply,
which reduced
system repeatability and accuracy in flow control.

A Stress Wave based Communication System for Concrete Structures

Background/Motivation

Concrete structur
es experience cracks and damage

over

time from environmental attack
.
The health of the concrete structures should be monitored at regular intervals in order to
ensure safety. A reliable method of real time communication will facilitate more frequent
structural health monitoring updates, allowing operators to detect cracks

almost
immediately when they occur to avoid catastrophic consequences. Developing a
communication system that utilizes guided stress waves traveling

(illustrated below)
within the concrete structure itself to allow communication over distances will free
s
tructural health monitoring from costly installation of communication wires and thus
increase the usage and scope of such techniques.

Piezoceramic material, sometimes simply called 'piezo', possesses the property of
piezoelectricity, which describes the

phenomenon of generating an electric charge in a
material when subjected to a mechanical stress (direct effect), and conversely, generating
a mechanical strain in response to an applied electric fiel
d. A commonly used
piezoceramic

is Lead Zirconate Titana
te (PZT), which has a strong piezoelectricity effect.
PZT can be fabricated into different shapes to meet specific geometric requirements. This
property
allows

piezoelectric material to act as both an actuator and a sensor
, which
can be integrated into str
uctures.

A p
iezoelectric transducer is very delicate and is easily deteriorated by
vibration

during
the casting of
a
concrete structure. In order to prevent this, a piezoelectric patch is first
applied with an insulating coating to prevent water and moistu
re damage and then
inserted into a cubic concrete block to form a
smart aggregate
. This smart aggregate can
be inserted at the desired position in a concrete structure before casting.

In this
project
,
p
iezoelectric transducers
in the form of smart aggrega
tes (shown below)
will

be used as actuators to send a modulated signal to carry concrete status information
and also can be used as sensors to capture the transmitted signal.


Purpose/Objective

In this project, a
piezoceramic
-
based
stress wave communication system
using a
microcontroller will be designed and developed for structural health monitoring
applications.
Several commonly used communication methods will be implemented to
demonstrate the stress wave communication via a concre
te structure. Controlled by the

microcontroller

by using a communication method, one smart aggregate

(as
a
transmitter)
sends a modulated
stress wave signal, which will propagate along the concrete structure
.

The stress wave
will be detected by

othe
r piezo
electric transducer
s
.
Through decoding the
detected stress wave, the carried information can be obtained
