1. Introduction

1.1 Purpose of the requirements document

This Software Requirements Specification identifies the requirements for the COQP project. We must present the requirement to others contributors in case of a open source project. This document is a guideline about the feature of our system.

1.2 Scope of the product

  • Our software is a software who show the state of a room (empty oroccupied) and stream a video of the room in the same interface
  • It's used enocean sensor . This sensor are wireless and self-powered
  • We use Openhab to create or interface . This software is open-source

1.3 Definitions, acronyms and abbreviations

  • Openhab :openHAB is a software for integrating different home automation systems and technologies into one single solution that allows over-arching automation rules and that offers uniform user interfaces.
  • MQTT: MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol.
  • EnOcean: A kind of various sensors wireless and self powered . Enocean sells sensor and software to use it.
  • VLC: VLC is a multimedia player who can translate a lot of flux and streaming .

1.5 Overview of the remainder of the document

The rest of the SRS examines the features and specification of COQP project. Section two presents requirements (constraint,user characteristics) and user characteristics .Section three contains the detailed ,specific and functional requirements and performance system .

2. General description

2.1 Product perspective

2.2 Product functions

2.3 User characteristics

The user just needs to know how to interract with our openhab interface. It's can be use a tablet or a keyboard and a mouse.

2.4 General constraints

  • Environemental constraints :
- An internet acces for connection to Dysoweb
- The computer with openhab must be near to the sensor

2.5 Assumptions and dependencies

-The site must have internet acces (ethernet or wifi)
-The site must have no much radio signal (interfere with our sensor)
- The sensor must be near the openhab server.

3. Specific requirements

3.1 Functional, non-functional and interface requirements

  • document external interfaces,
  • describe system functionality and performance
  • specify logical database requirements,
  • design constraints,
  • emergent system properties and quality characteristics.

Function

For the raspberry Pi

- Establish the communication between sensors and the raspberry pi and between the raspberry pi and an mqtt server .
- Analyse data from sensor to deduct if someone is inside the room
- Send the state of a room to dysoweb via mqtt


For the android's tablet

- Book a room with the tablet
- Establish the communication between dysoweb and the tablet

Description

Inputs

- sensor's data message
- room's calendar
- notification of reservation

Source

-A sensolux presence sensor to send data to raspberry pi via EnOcean radio signal
-A Dysoweb calendar to have the state of the room
-A android's tablet to send notification of reservation to Dysoweb

Outputs

-Android's tablet
- Calendar of the room on Dysoweb

Destination

-Users of Dysoweb
-Users in front of the android's tablet

Action

-The programm detect if a person is inside the room
-The programm check on Dysoweb if the room is booked or not
-The programm make a book for the room

Non functional requirements

-Nothing hides the SENSOLUX Presence sensor
-Have a source of ligth inside the room to charge the energy storage device
Have a wifi internet connection to connect the android tablet and the raspberry pi

Pre-condition

  • materials conditions:
- A Sensolux presence sensor inside the selected room.
- A MQTT server connected to Dysoweb and sensors.
- A android tablet connected to Dysoweb.
  • Software conditions:
- Install openHab software on the linux server.

Post-condition

-The user can book a room with the tablet if it's empty
-The user have a feedback on the state of the room via dysoweb or the tablet

Side-effects

4. Product evolution

-Use several sensor on the same openhab server
- Design a kind of main openhab to an administrator
- Secure the accees of openhab /MQTT
-Using severall Enocean dongle with one openhab server
-Book a room with nfc
