Darti project sensor information backend

Darti Backend (WIP)

Demos

• Backend (repo)
  • Basic crud with test data + pagination
• Frontend (repo)
  • Charts + Sensor List/Create

Usage

Install postgres and redis or run them locally docker/docker-compose:

docker-compose -d postgres redis

• Postgres and Redis configurations are in aep/settings.py
• DB migration files are in aep/migrations/

Install dependencies (on Ubuntu):

sudo apt-get update && sudo apt-get install -y build-essential libpq-dev

Python dependencies:

virtualenv -p /usr/bin/python3.7 venv
source ./venv/bin/activate
pip install -r requirements.txt

Run app:

python -m aep.app

The backend will be available at http://localhost:8888/

To run tests:

pytest

Architecture

Backend stack

• Python 3.7
• PostgreSQL 11 + PostGIS
• Redis 5
• aiohttp
• asyncpg
• aioredis

Basic data model

• Area: A named area in a map. A polygon defined by a list of points with GPS coordinates.
• Sensor: Sensor with a type, an identifier and GPS coordinates.
• Activation: It represents the activation count of a Sensor in a specific reading instance.
• Reading: A reading represents the state of the sensor network in a specific moment in time. It also contains weather information, the system status and GPS coordinates.

Roadmap

• User Authentication + Roles and permissions.
• PostGIS integration for Area polygons in crud + query sensors by Area.
• Better pagination.
• Improve filtering for reports.
  • Activations by Sensor per month/day and Area
  • Aggregate Activations per month/day and Area
  • Aggregate weather info per month/day and Area
• API Docs (swagger?).
• Improve caching mechanism.
• Database migration tool that doesn't use psycopg2

About the project

Chagas Disease

In Paraguay, as well as in other Latin American countries, Chagas disease is one of the pressing issues in the area of public health.

This disease is caused by the parasite Trypanosoma cruzi, being Triatoma infestans insect or commonly called vinchuca (kissing bug), the main vector of South America.

Currently, there is a concern in European countries and on the United States, due to the growing eco-tourism to South American countries, where Chagas disease is referred to as an "exotic disease". Prevention mostly involves eliminating kissing bugs and avoiding their bites. A vaccine has not been developed as of 2019.

Treatment options for infected patients are limited. Early infections are treatable with the medication if given early, but becomes less effective the longer a person has had Chagas disease.

Most people with the disease live in poverty, and do not realize they are infected.

Eradication of Chagas Disease with Technology

A project in conjunction with the Center for the Development of Scientific Research (CEDIC) and the Polytechnic School of the National University of Asunción.

The monitoring of the vector transmitting Chagas disease will be possible through the implementation of a wireless infrared photoelectric sensor network for remote early detection of kissing bugs infestation in a surveillance zone. Readings of the sensor network will be sent from a ground station to the research lab located in the Polytechnic School using a satellite.
