Team Vision for System-Level Design Phase

During this phase of the project, our team had a few main goals in mind. We had hoped to finish acquiring and taking inventory of all hardware from the Ionia site, discussed all edits or revisions to the GUI, and begun testing some of the software from the previous team.

Due to space limitations, and the time restraints on acquiring a key to the RIT Observatory, we did not complete the inventory and acquisition of hardware. Limited by the hardware that was not available to us, we focused our time on planning and high-level design. After acquiring our key(s) to the observatory, we planned out a space to install the dish that would have no impact on other users of the observatory. We also went through different functional concepts and selected one to focus on, based on feasibility and other criteria. From this concept, we developed a functional block diagram, and started discussing each function in more detail.

Feasibility: Prototyping, Analysis, Simulation

Feasibility - Run Integrated System

Single Parent Software vs Individual Control Systems:

Multiple Related Software:

Feasibility - Wake up/Go to sleep

Read data from an online weather service:

Feasibility - GUI

Modify and improve the current LabView GUI:

Build web based application:

Feasibility - Error Monitoring

MSP430:

LED Detection on Security Camera:

Feasibility - Weather Protection

Read wind speed from the sensor - Most accurate, instant reading allowing dish to immediately go into a safety position

Snow - Not so straight forward. Read data from online weather service to prepare dish for upcoming storms

Feasibility - Interference Reduction

Feasibility - Storage

500 GB SSD

Assume up to 200 MB per day with various other files
