AST-Monitor is a wearable Raspberry Pi computer for cyclists

AST-Monitor --- A wearable Raspberry Pi computer for cyclists

---

This repository is devoted to the AST-monitor, i.e. a low-cost and efficient embedded device for monitoring the realization of sport training sessions that is dedicated to monitor cycling training sessions. AST-Monitor is a part of Artificial Sport Trainer (AST) system. First bits of AST-monitor were presented in the following paper.

Outline of this repository

This repository presents basic code regarded to GUI. It was ported from the initial prototype to poetry.

Hardware outline

The complete hardware part is shown in Fig from which it can be seen that the AST-computer is split into the following pieces:

• a platform with fixing straps that attach to a bicycle,
• the Raspberry Pi 4 Model B micro-controller with Raspbian OS installed,
• a five-inch LCD touch screen display,
• a USB ANT+ stick,
• Adafruit's Ultimate GPS HAT module.

A Serial Peripheral Interface (SPI) protocol was dedicated for communication between the Raspberry Pi and the GPS peripheral. A specialized USB ANT+ stick was used to capture the HR signal. The screen display was connected using a modified (physically shortened) HDMI cable, while the touch feedback was implemented using physical wires. The computer was powered during the testing phase using the Trust's (5 VDC) power-bank. The AST-Monitor prototype is still a little bulky, but a more discrete solution is being searched for, including the sweat drainer of the AST.

Software outline

Dependencies

List of dependencies:

Package	Version	Platform
PyQt5	^5.15.6	All
matplotlib	^3.5.1	All
geopy	^2.2.0	All

Note: openant package should be installed manually. Please follow to the official instructions. If you use Fedora OS, you can install openant package using dnf package manager:

$ dnf install python-openant

Additional note: adafruit-circuitpython-gps package must be installed in order to work with GPS sensor:

$ pip install adafruit-circuitpython-gps

Installation

Install AST-monitor with pip:

$ pip install ast-monitor

In case you want to install directly from the source code, use:

$ git clone https://github.com/firefly-cpp/AST-Monitor.git
$ cd AST-Monitor
$ poetry build
$ python setup.py install

Deployment

Our project was deployed on Raspberry Pi device using Raspbian OS.

Run AST-Monitor on startup

Add following lines in /etc/profile which ensures to run scripts on startup:

sudo python3 /home/user/run_example.py
sudo nohup python3 /home/user/read_hr_data.py  &
sudo nohup python3 /home/user/read_gps_data.py  &

Examples

Basic run

from PyQt5 import QtCore, QtGui, uic, QtWidgets
from ast_monitor.model import AST
import sys

# provide data locations

hr_data = "sensor_data/hr.txt"
gps_data = "sensor_data/gps.txt"


if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    window = AST(hr_data, gps_data)

    window.show()
    sys.exit(app.exec_())
