Denver using RFID project launched the nation's largest bike sharing
In recent years, a bike-sharing activities rise gradually throughout the world, working in the city of passengers and visitors a convenient, zero-emissions transport options. Lyon, France and Quebec, were all carried out this type of bike share program. Last month, Denver also joined the trend, launched the B-cycle project, which is by far the largest bike sharing program, a total of 500 used bicycles, located in the city 50 RFID bike site (B-stations) .
System by the Kiosk Information Systems B-stations supplied by the bike rack and a lock similar to automated teller machine kiosks composition. Bike lock by lock bits fixed frame. A bike station at least five lock-bit, up to 25. Lock-bit number of the number of different sites depending on the use of bicycles. Overall, the average share of 1.5 per bike lock. Users can access in two ways bicycle. Is with the user using the letter cards in the bike station kiosks to buy short-term, 24-hour membership. Users can first select a bicycle, when the transaction is complete, the system tick uttered a sound, and light green, indicating the selected bike unlocked, the user can take the bus.
Those who regularly use the B-cycle program users, they can be purchased online 7 days, 30 days or annual membership (all bike station common). After the user completes a purchase, receive the B-cycle of a project team mailed to RFID cards - also known as B - card. Using B-card, the user can select directly from a bike station car, card reader, unlock, and pick up the car, without use of kiosks.
Project B-cycle LLC is responsible for the company's chief marketing officer Andrew Davison said, using B - card is more convenient for users to pick up the car without waiting in line at the kiosk.
Card supplied by the Synometrix. Each card contains a passive low-frequency RFID inlay, the work frequency of 125 kHz, consistent with EM Microelectronic EM4100, EM4102 and EM4200 RFID chip agreement. Take car, the user presses a button next to the selected bike, this action activates the stent embedded RFID readers (all locks are each corresponding to a RFID reader). Users will be closer to the button next to a small card brand, readers collect the tag's unique ID code, which Internet connection to send information through the site to a central B-cycle database. If the user account status is normal, the primary database direct B-station unlock the bike lock. At the same time, the user will receive notification sound and green light, the user must be removed within 30 seconds the car, or bike will be locked again automatically.
Regardless of the user through a credit card or B-card pick up the car, in front of the car to take the reader has to collect a bike tag ID code and ID code sent to the central database, so the system on the bike and use the user correspond.
Back to cars, users simply point to any B-station to find air lock, the lock will be the bike into the position. System the green light, and issued DI sound, indicating a bike has been successfully locked, the user account has been updated. Back to car, bike tag reader also collect ID code, send the information to the central database.
Embedded GPS device records the bike route users. When the user back to car, GPS information together with the bike tag ID code to be uploaded to the database. This helps B-cycle project to understand the user the most commonly traveled route and the daily routes based on user collaboration and business users provide products or services.
According to Davison said, B-cycle project team are interested in launching mobile applications, use of mobile phones with NFC module to take a bike. However, this may require a bike site new readers, because the operating frequency of NFC tags 13.56MHz, based on high-frequency RFID standard ISO 14443.
