  1. AMR Automatic Meter Reader By: Power Communication Systems (PCS, Inc.)

  2. Team Members # 1 Teacher & Advisor 2001- 2002 Team Leader: Marc Lewis Derrick Cherry Dr. Noel Schulz Daven Carter Samuel Jefferson III Brian Wells

  3. Problem: The existing automatic meter reading systems used to monitor power usage are extremely expensive. • Costly Installation • Costly Communication Techniques The conventional meter reading systems are expensive to maintain and lack competitive qualities. • lack accessibility in bad weather conditions • Do not optimize network • Costly to read Solution: • Decrease cost by designing a retrofit device • Increase accessibility by using an Automatic Meter Reading System • Optimize network by using wireless system

  4. Block Diagram Comparator Hex Schmitt-Trigger Inverter Infrared Sensor Meter Amp PIC PC Wireless Communication Module

  5. AMR Hardware Components RS232 Cable Hex Inverter PIC w/ built-in A/D Converter Creatalink 2XT Module (Motorola) Infrared Sensor RS232 Cable ABB Meter PC

  6. Design Requirements:

  7. Design Requirements(cont.):

  8. Achieved Percentage: 100% Emission: (Radiant Output vs. Distance) Actual Distance: 2.5 – 3.0 Projected Distance: 2.0

  9. Achieved Percentage: 50% Performance: (Projected vs. Actual) 98 % @ 16 RPM 100 % @ 8 RPM

  10. Achieved Percentage41% Creatalink Interface w/ PC • Change PC Configurations to accommodate Creatalink • Change Creatalink Configurations to accommodate the PC

  11. Achieved Percentage: 85% Packaging: (PCB Layout) RS232 Interface Micro Processor (PIC) 2.0 in Onboard Port Circuitry Power Supply Infrared Sensor 3.0 in • Link between Creatalink and PIC • Infrared Sensor & Transducer Circuitry • Onboard Re-Programmer

  12. Achieved Percentage: 100 % Cost: (Projected vs. Actual) $ 150 $120

  13. Achieved Percentage: 100% Battery: (Projected vs. Actual) Need 5 hours/ year 170 hours (Lifetime) Life Expectancy of Battery = Battery Rating = 1700mAh = 170 hours total current drain 10mA

  14. Design Issues • Interfacing w/ Creatalink & PIC • Creatalink will be driven by PIC • PIC & Creatalink will need X- Modem Protocol • Interface w/ Creatalink & PC • Powering System • Spring Clip or Plug- In (Depending on type of Meter) • AC – DC Converter • Half-Wave Rectifier on the Circuit Board • RS 232: PIC – Creatalink • Slightly Cut the Side of the Meter Case • Signal Quality of Input to Transducer • Signal-to-Noise Ratio < 16db
