As urban travel becomes smarter,eco-friendly,and more convenient,rental electric bikes are increasingly favored.While offering convenience,
the issue of indiscriminate bike parking poses challenges,leading city authorities to restrict operations.To address this,OMNI IoT has developed
the electric bike system in mid-2020.Current bike parking solutions,such as GPS and UHF 900MHz,face limitations.
The GPS solution offers a location accuracy of 2-3 meters but is hindered by obstacles like tree canopies or buildings,
leading to suboptimal user experiences.The UHF 900MHz solution provides a location accuracy of around 0.5 meters,but the high cost
of card readers poses a challenge.Many electric bike system providers or companies are exploring the 13.56MHz NFC technology due to
its outstanding performance,cost-effectiveness,and security advantages.However,the NFC solution's designed recognition distance is
limited to 10cm-20cm,and signals may be affected to varying degrees in complex environments,failing to meet the 25cm recognition
distance requirement for shared electric bike customers.
Summarizing,NFC-based precise parking for rental electric bikes faces technical challenges,including metal interference,
environmental factors,a distance which is more than 20cm from the ground,low maintenance cost,and no power supply.To overcome
these challenges,OMNI IoT introduced an optimized NFC precise electric bike parking solution with goals to enhance user satisfaction,
meet parking standards,ensure low implementation and maintenance costs,provide a long lifespan for ground labels,and achieve a
recognition distance which is more than 25cm.
To ensure the successful implementation of the electric bike system,several ingenious designs were incorporated to
address various application challenges:
Parallel Layout of Tags:
Tags are arranged in a side-by-side configuration for optimal functionality.
Adaptation to Common Ground Covering:
The electric bike system accommodates regular ground asphalt paint,overcoming challenges related to high temperatures
and material bending or breakage.
Installation of Card Readers at the Bottom of Shared Electric Bikes with NFC Antennas and Ferrites:
Card readers are strategically placed on the bottom of shared electric bikes,incorporating NFC antennas and ferrites
to enhance performance.
To validate the practicality of the solution,OMNI IoT,conducted simulations involving real vehicles and road conditions.
The results demonstrated that the electric bike system achieves a reading distance of over 27cm,with a front-to-back tolerance
moving recognition distance of over 7cm and a recognition width reaching 30cm.This fully satisfies the operational requirements
for shared electric bikes or rental electric bikes in urban mobility solutions!
