RFID-Based Positioning System: Feasibility Analysis for Vehicle Lab Floor

This feasibility analysis explores the hardware, financial, labor, software aspects of implementing an RFID-based positioning system for a 7x7m vehicle lab floor. The study reveals the testing results showing a max vehicle speed over 6 m/s and the required tagging spacing for 10 cm accuracy. Financially, the estimated cost per tag, reader cost, and overall budget implications are examined, making it possible to tag 21x21m^2 of the floor area. Labor feasibility considerations include the necessity of unique numbering, bulk tagging methods, and time-efficient processes. Software feasibility involves investigating reader compatibility with various operating systems and developing software for efficient tag information reading and system positioning using RFID technology.

Presentation Transcript

  1. RFID Based Positioning System – Feasibility Analysis • Hardware Feasibility • Testing using turn table shows max vehicle speed can be > 6 m/s. • Spacing required for 10 cm accuracy is 10 cm • Multiple tag information doesn’t improve accuracy unless distance of reader to tag is known (possibility of improvement in future). 10 cm

  2. RFID Based Positioning System – Feasibility Analysis • Financial Feasibility • Vehicle Lab Floor Dimension appx. 7x7 m2 = 4900 cm2 • For 10 cm accuracy, we need inter-tag spacing to be 10 cm • Number of tags need for entire floor is appx. 5000. • Estimated cost per tag in bulk rate = $ 0.5 • Cost of tag/ sq. cm = $ 0.5 • Cost of reader appx. = $80 • Cost of 30 vehicles => $2400 • tagging Veh. Lab = $5000 • With budget = $25,000 and 30 vehicles • Possible to tag 21x21 m2 of floor area with 10cm accuracy

  3. RFID Based Positioning System – Feasibility Analysis • Labour Feasibility • For vehicle lab 7x7 m2 of floor area • 5000 tags • Unique numbering, factory reset? • Sticking them on the floor • individually (time consuming, erroneous) • in bulk, assuming they come in reams with desired spacing, would be less time consuming. • Need to find this out.

  4. RFID Based Positioning System – Feasibility Analysis • Software Feasibility • TI Readers only have .dlls, => windows • Need to call them and inquire about other OS support. • Skyetek supports Linux, Win, PDA for their readers • Need to inquire about Zaurus Linux support. • Develop software that will allow reading of tag info. using RS232 protocol. • Develop API for positioning system using RFIDs.

  5. RFID Based Positioning System – Feasibility Analysis • Roof solutions • surface 530m^2
