Spring 2006 Quarter Plan Presentation

• UCSD TIES
• Lakeside Environmental Monitoring Team
• April 25, 2006
• Team Lead Stephen Bak

2
Agenda

• Water Quality
• Hardware Development
• Structural Development
• User-Interface
• Overall Goals

3
Water Quality Monitoring and Assessment

• Evan Sharbrough (lead)
• Meng Wei Chou
• Sam Hwang

4
WQ Quarter Progress

• New phosphate kit for improved accuracy
• Established site visit days and field tests.
• Initialized planning for integrating WQ team in
  user-interface development.
• Assisted with sensor calibration.
• Tested at sites 1-5 on April 16th.

5
Whats To Come

• At least 3 remaining site visits for testing
• April 29th - Coinciding with prototype field test
• May 13th
• May 20th
• Periodic Testing at HaHana (Site 6) and El
  Capitan Reservoir (Site 8).
• Contribution to user-interface layout and
  displays.
• Evaluation of statistical analysis software.

6
Current Issues and Obstacles

• Preliminary site 6 and 8 evaluation
• Site 6
• Generally higher TDS and EC than site 2.
• Consistently lower temperature
• Higher than desired levels for other parameters
• Site 8
• No definitive link to sites in town yet, but also
  outside of desired ranges for many parameters.
• Recommendation
• Continue testing both sites but less frequently
  than original 5 sites.
• Continue searching for source from San Vicente
  Reservoir?

7
Hardware Development Team

• Software
• Tony Aung (lead)
• Nick True
• Hardware Testing
• Daniel Su

8
Progress in Programming

• Began coding wireless transmission algorithms.
• Debugging local data storage code.
• Developed possible design for the wireless
  communication within multiple sensor node
  network.

9
Hardware Testing Accomplishments

• Sensor calibration
• EC first calibration
• DO recalibration with correct method
• Charge regulator study and testing
• Tested power consumption characteristics
• Encountered problem with charge regulator.
• In contact with Morningstar for solutions

10
Hardware Development Goals

• Independent execution of code within the
  datalogger
• Wireless Communications Issues
• Range testing of modem
• Complete transmission programming
• Power system characteristics
• Battery drain duration.
• Battery charge time.
• Rooftop simulations with solar panel
• Recalibrate remaining sensors

11
User Interface Design Team

• Jason Najarro

12
Quarter Plan

• Deliver Working Lakeside Office Interface
• Start Developing Server Database

13
Office Interface

• Based on Stephen Frosts interface designs, UI
  team will select important features to include in
  prototype interface
• Collaborate with Chemical team to program
  interface in LabVIEW 8
• Present working prototype by end of quarter

14
Lakeside Database

• Obtain donated copy of SQL Toolkit for LabVIEW
  from National Instruments
• Begin implementing database on team laptop
• Database can later be transferred to server once
  it is ready
• Run a test collection of sensor data

15
Structural Development

• Scott Maghy (lead)
• Tim Chow
• Jeanie Kwok

16
Structural DevelopmentWinter Quarter
Accomplishments

• Relocated placement of the system along the 2nd
  to 3rd step joint from the Channel Road Bridge
• Completed finished, detailed models for the
  conduits
• Initiated the process of approvals with the city
  of Lakeside

17
The Enclosure

• 0.75 thick reinforced fiberglass walls
• lockable steel hasp
• humidity/dust resistant seals
• brackets for wall mounting
• Cost 195

Campbell Scientific enclosure model ENC 12/14
with components
18
The Approval Process

• System needs approval from SD County Land
  Development Section
• Currently in contact with county workers
• Approval will include system installation, the
  wall, and the safety fence
• Approval process about two weeks
• Submission of approval to SD County within next
  two weeks

19
Important Issues

• Fence details
• Placement of the solar panel
• Who will install the system?

20
Structural Goals

• Purchase and modify the enclosure
• Further develop solar panel mount design
• Finalize the approvals needed to put up a fence
  and bolt into the wall at Lakeside
• System installation

21
Recap

• Greater integration of WQ team into design as
  well as continued testing
• High emphasis on programming and system testing
• LabVIEW representation of User-Interface
• Obtain approval and all materials to install
  structural system

22
Overall Goals and Dates

• Tentative Field Test April 29th
• Pre-Deployment Field Test Mid-May
• Deliver a functioning prototype by end of quarter
• Initial target date Mid-to-late May
