Application |
|
uGraph is a Microsoft
Windows based program designed for the non-realtime presentation of data
obtained using CR1000 /
CR800 datalogger in
graphic as well as tabular formats.
With proper
configuration, uGraph has been successfully used for instrumentation
projects including multi-stories buildings, tunnels, deep excavations,
railways, subway systems, airports, dams, and hydroelectric schemes. |

Data Acquisition |
|
uGraph is
primarily designed for use with data collected with Campbell Scientifics’
data loggers. Before the data can be processed by uGraph, the data can be
collected in the field with a portable PC running PC208W or a Palm PDA
running PConnect and be transferred on to the PC’s hard disk.
Alternatively, data can be collected remotely and automatically via
communication devices such as short-haul modem, telephone modem and radio
modem, etc. |
|
Data Processing |
uGraph
organizes data from data logger into project database. Raw data from
up to 200 sensors per logger are processed and stored in a database that is
compatible with Microsoft’s Access 97. Information including the sensor’s
calibration factors and how to present the data are also contained in the
database.

|
Graphical Data Presentation |
|
uGraph comes with facilities
to graph and to replay historical data for reporting and post analysis. The
data can be displayed in trend graphs, in profile plots, or in plan view or
section view similar to the real-time display. |

Trend
Graphs |
Data readings from a group of sensors against
time
|
Graph data can be exported to Microsoft
Excel for additional processing

Profile Plots
The graph on the right presents the profile plot of a string lof linked EL
beam sensors |
 |
|
Plan or Section View
The readings of the sensors are displayed over images of site
in plan view, section view, or actual photograph as the example on the
right. |
 |
|
Alarm Checking |
|
Up to three alarm thresholds can be assigned to
each sensor. While running in plan or section view, uGraph will test
readings from each sensor against the alarm limits and display the readings
in green, blue, amber, and red accordingly. The figure below showed sensor
readings are displayed in appropriate locations, color-coded for alarm
status, and with instant access to trend plots for past three days.
