IoT for Home Automation – Custom Gateway, Cloud and Mobile App

Tags : IoT for Home Automation

Category : Automation , Home Product Case , Product Engineering

Description

Design and development of IoT Home Automation architecture with following components:

Sensor networks – installed to capture data from lights, AC, blinds, AV units, doors, and more
Custom IoT gateway device – to connect sensor networks to cloud backend
Cloud backend – for data analytics
iOS/Android App and web-dashboard – UI and front-end to facilitate human and machine interactions

The system demonstrates:

Home automation scenario which comprises sensor networks [lights, AC, blinds, AV units] that interact with mobile app [iOS, Android] or web dashboard via the custom IoT gateways and the cloud, using MQTT.
The sensor networks convey a wide range of home device information (temperature, humidity, ambient light, human proximity) that is transmitted over various wireless communication protocols like Infrared, Bluetooth, Wi-Fi, EnOcean, Zigbee.
This information is broadcast to the cloud for data analytics and data in actionable format is displayed on smart handheld devices for the end-users.

This is how the system works:

The custom gateways act as a mediator between the sensor networks and the cloud, providing connectivity, security and control.
The cloud backend, built using Python and Django, runs applications that analyze data from the sensor networks to collate and relay valuable information that can be used for decision-making.
The interface that gives the end users control of the system is accessible through the app on smart devices [Android, iOS] or web dash-board. The UI provides one-touch control of single or group-actions.

System Architecture – An Overview

Tools and Technology:

Sensor networks designed based on ZigBee, EnOcean, Bluetooth and Wifi protocols/technologies
Custom gateway hardware and software design to enable compatibility between sensor networks and end-user devices
Design, development and integration of cloud-based SaaS. Data analytics that make predictions possible
iOS/Android App and a web dashboard that delivers ‘delight’ to end-users through our intuitive UI/UX

Features (snapshot):

The system includes multi-action settings for automation of more than one device for an event
Sensors that support automation [door sensor, proximity sensors, beacons, etc.] are used to trigger multiple actions. For example, when the proximity sensor detects that you have crossed the range/perimeter, the AC and lights will be switched off, and the blinds will be opened.

Intelligent Vision Sensor platform for Machine Vision applications

Category : Automation , Home Product Case , Product Engineering

Business Challenge:

To design a state-of-the art intelligent vision sensor platform that facilitates development of multiple machine vision applications.
This cutting-edge vision sensor platform had to cater to multiple product lines across multiple generations of hardware systems

Embitel Solution:

Our team successfully designed and developed a flexible and scalable architecture for intelligent vision sensor platform (for firmware and associated PC application)
We integrated industrial protocol stacks – Ethernet/IP and Profinet, defined telegrams for multiple interfaces and designed a web interface for remote access of vision sensors.

Embitel Impact:

This platform now caters to five different product lines across three generations of hardware systems.

Tools and Technologies:

All the systems have been designed using Texas Instruments application processor
The firmware applications have been developed on Linux OS
The Sensor has been configured with the help of HMI (Human Machine Interface) designed and developed using QT

Fleet Management Telematics devices

Category : Automation , Home Product Case , Product Engineering

Business Challenge:

The software architecture of our customer’s telematics fleet management applications was not modular. Due to absence of various required drivers (not readily available in market), each module was being accessed through application layer using driver level commands

Embitel Solution:

We collaborated with our customer across product lines – GPS fleet security, vehicle and trailer tracking
Our team worked on specialized microcontrollers and M2M (Machine to Machine) modules for which power efficiency is a critical factor
Development of drivers and application for iButton technology and one wire protocol for different Temperature Sensors, Humidity Sensors, Current Sensors, Voltage Sensors and EEPROM
Design and development of a driver for STX3 Globalstar Sattelite network transmitter module for AVL (Automatic Vehicle Locator) in geographical area where mobile network is not available.
Driver development for GPS modules of UBlox.
Driver development for radio modules from Novatel Wireless (Enfora)
Driver development for CDMA, 2G and 3G network modules from UBlox
Different interfaces were created under these radio drivers for data transfer using UDP, TCP, HTTP protocols and SMS (Short Message Service).
J1939 and GPS simulator (JGPS Simulator) development for fleet device testing

Embitel Impact:

Drivers developed by Embitel are not available as off-the shelf solutions in the market and required detailed customizations for our customer
All our GPS and radio modules drivers are designed in a way that they can be used either in 32 bit or 16 bit microcontroller easily by selecting the HAL (Hardware abstraction layer) file
Our JGPS simulator has helped our customer achieve time and cost savings on testing of devices

Tools and Technologies:

Controller: STM 32F103ZF (Arm Cortex M3, 32 bit), TI MSP430 (16 bit)
Third party modules like pyQT (for designing framework GUI) and Psutil (to monitor running proceIDE: Keil uVision4, Code composer studio 5, Visual studio
RTOS: Keil RTX
Language: Embedded C (For all drivers), C# (For JGPS simulator)
