ELECTRONICS TELECOM

Problem Statement

• High-level statement of system need

• Example:

– Locate and display the physical position of a – Locate and display the physical position of a mobile device

ELECTRONICS TELECOM

Functional Requirements

– Battery operated and replaceable– Stand-alone, self-contained intelligent unit– attached to anything– Size– Weight– Simple user interface with Prog/diagnostic port– Locates itself anywhere on earth with lat-long with elevation

output– Weather-proof to work in any existing earth-based condition– Store and forward operation– Communicate position via COTS wireless network in pseudo

real-time– Display position information from multiple devices using GIS-

based GUI

ELECTRONICS TELECOM

Conceptual Block Diagram

• Depicts requirements in pictorial diagram format

• Supports interaction, discussion and development of performance requirementsdevelopment of performance requirements

• Include all elements of system

• May require multiple diagrams

Performance Requirements

• Defines needs for each subsystem to be developed

• Expands on each of the Functional RequirementsRequirements

• Used to transition from Conceptual to Functional block diagram

• Examples

ELECTRONICS TELECOM

Performance Requirements

– Battery operated• Internal• Replaceable• 24 hours of continuous operation – determines amp-hour rating• External recharge of battery • Voltage = > 3.0Vunregulated input• etc

– Stand-alone, self-contained intelligent unit– Stand-alone, self-contained intelligent unit• Processing power

– 8 or 16-bit processor– programming interface– DI/O – 8 bits– No analog

• Memory– program– storage – 100 messages not non-volatile memory

• Interfaces– User I/F – serial >9.6Kbps– Location Det – serial >9.6Kbps– Wireless Comm – TCP/IP >56Kbps

• Etc

ELECTRONICS TELECOM

Performance Requirements

– Attach to wood or metal or cardboard devices that exceed 2x2x2 feet • Remove without destroying• Magnetic or screw mount• Peel-off tape

– Size• Thickness must be less than 2 inches• Length and width should be less than 5 inches

– Weight– Weight– Simple user interface with Prog/diagnostic port– Locates itself anywhere on earth with lat-long output– Weather-proof to work in any existing earth-based condition– Store and forward operation– Communicate position via COTS wireless network in pseudo real-time– Display position information from multiple devices using GIS-based GUI– Cost – Unit 1 fabrication

Deliverables

• Something of “Value” to the customer• Interim

– Provided to stakeholders during the project execution

• Final– Provided at the completion of the project

• Description• Description– Detailed

• Timeline– Graphic of due dates for each deliverable and status updated

weekly

• Example:Schematics will be created and submitted for the remote monitor, expansion module,

power inverter, and peripheral interface board. They will be created with the schematic

capture program in Multisim. Schematics will be printed on 8.5 x 11 inch sheets of paper and

may employ subcircuits to achieve this format. Subcircuits will have input and output labels as

well as a meaningful subcircuit title. All symbols created while developing the circuit will be

submitted via the Multisim user database in the softcopy format of the schematic. Additionally,

symbols from OI Analytical’s current library may be used to aid schematic development. This

deliverable will be submitted in both softcopy and hardcopy format. Hardcopy printouts will be

printed in landscape orientation.

Milestones

• An “Event” that indicates significant progress

• Description– Detailed

• Timeline– Graphic of due dates for each milestone and status updated – Graphic of due dates for each milestone and status updated

weekly

• Example:The first milestone is the approval of the completed test plan. The test plan will define

the parameters for passing or failing each piece of hardware and software. It will also set the

structure for collecting test data. Extensive testing will guarantee that the prototype meets all requirements and will ensure the project’s success. This milestone will be completed by

September 7, 2009.DEMONSTRATIONS
