Our Product

In this hackathon, we made an anti-theft IoT device GeeBikeLock which can be installed on a bike. Its main features are:

• It can be installed on any bike.
• It's equipped with GPS and accelerometer in order to detect if it's stolen.
• Equipped with RFID. You can lock/unlock it with your student ID card.
• We also have a cloud server. You can login the website to fully control the lock.

Directory Structure

• demo.mp4: The live demo video. (in Mandarin)
• GeeBikeLock.pdf: The slide.
• geebikelock.ino: The source code running on Arduino, our IoT lock.
• website: The cloud backend server as well as the website.
• sock_server.py: The "bridge" which connects between the IoT lock and the server.

• addBike.py: A test script to emulate an IoT lock returning its current state.
• usb2remote: Because we encounter some problem when installing Arduino's wifi module, we choose to perform port forwarding between Arduino USB port and remote webserver port. This is strongly deprecated.

Specification

Auduino transmits to sock_server:

• id (bike-id) can only cantain alphanumeric chacracters. (i.e. [a-zA-Z0-9])
• uid is RFID, represented as a 8-digit hex number.
• If no card is readed, simply return uid=00000000.
• In the source, the GPS location is generated in random due to debugging.

id=bike7122
lat=121.239156
lng=25.033570
x=0.79 
y=0.27 
z=-0.42 
uid=00000000
*

sock_server to web server(backend):

• uid is represented as a interger.
• gps[0], gps[1] = lng, lat

Send HTTP POST to bike.csie.org/map/[BIKE_ID]/. The POSt data is in JSON format:

{
  "gps": [25.25245333, 121.54130],
  "axis": [0.8, 3.2, 3.32],
  "uid": 0
}

Dependency

• Website: Python3 web framework, Django.
• IoT Lock: Arduino equipped with accelerometer, GPS.
