R.F. Location Project General Design Transmitting Antenna • Transmitting Antenna • sends power signals Receiving Antennas Power Rectifier • Antenna arrays receive • power signal • Power is rectified and • amplified Amplifier • DC power signal is analyzed USB Interface 68HC11 Microcontroller • 2-D Location outputs to • Computer, LCD, or PDA • Bill Murray still confused.
Project Objectives Optimal Objective • Create a fully functional 2D location system Baseline Objective • Directional finding antenna
Chip Layout DATA BUS Receiver Output RAM ROM FPGA 10 68HC11 • RAM: • Temporary Receiver Variables Control lines to Antenna Array • ROM: • Software Storage • HC11: • Controls Antenna Array Switching • Interfaces with PC via USB • HC11 will read from external memory.
Software • Extrapolate data from USB interface • Program computer workstation to locate transmitter using C • Receives a bit pattern from each receiving unit, • Translates into a vector • Interprets vector into a graphical location
Software continued • Output data to screen • Interpret data to find a direction within a given boundary • Plot directions point for point on Cartesian coordinate 2-D plane
Software Controlled Hardware 1 Antenna Array • 68HC11 Microcontroller • Includes A/D converter, timers • USB interface between 68HC11 and computer workstation • 10-12 circularly polarized antennas • FPGA chip • ROM • RAM
HardwareAntenna Design Details • Transmitting Antenna Design • Monopole design, linearly polarized. • Receiving Antenna Arrays • Circularly polarized, electrically scanning • Signal Processed by 68HC11 Microcontroller • Includes A/D converter • Array Schematic not yet finished
Division of Labor • Chris, Marcus, Mike • Design and construction of transmitter, antenna array • Kara, Jake • Software for receiver switching, vector interpretation, visual output, interfacing between receiver and PC, and differentiating between I.D. tags.
Feasibility • 4 Microprocessors 68HC11 • 4 FPGA’s - 4 @ $100 (if used) • 4 32 K RAM - 4 @ $5 • 4 32 K ROM - 4 @ $5 • 4 FR4 boards - 4 @ $5 • USB cables - 120 ft. ~ $40
Market Analysis • Possible Uses • Warehouse Inventory Management • Small Businesses • Home • Tracking personal objects • Tracking animals (dogs, cats, hamsters) • Monitoring hospital patient locations
Project Risks • Parasitic foreign disturbances • Other electronic devices may disturb antennas • Time management • No benchmark so may take longer than expected
Additional Functionality • Specific ID • Tracking multiple tags • Determining location of objects in 3-D • Finding Shamu
