RICM4 2017 2018 - Serre Connectee / SRS
|0.1.0||05.02.2017||Timothée DEPRIESTER, Guillaume BESNARD||TBC||TBC||TBC|
1.1 Purpose of the requirements document
The Software Requirements Specification (SRS) is a communication tool between stakeholders and software designers. It gives a description of the software’s purpose and functionality. In other words, the SRS is a document that captures complete description about how the system is expected to perform.
1.2 Scope of the product
The project consist of upgrading a classic greenhouse to retrieve live information about its climate. This information should be available for the farmer to view locally on a screen.
1.3 Definitions, acronyms and abbreviations
- Greenhouse: an area, usually chiefly of glass, in which the temperature is maintained within a desired range, used for cultivating tender plants or growing plants out of season.
- LoRa: Long Range and low energy radio RF technology developed by Semtech. It's an open-source technology.
1.5 Overview of the remainder of the document
We'll then dive deeper into specification and requirements of the project.
2. General description
2.1 Product perspective
- The aim of this projet is equip to equip multiples farms, not only one greenhouse.
- This project may become a flagship project for ST MicroElectronics
2.2 Product functions
At the end, product should return:
- The air temperature
- The air moisture
- The soil moisture
And display these data on a local graphic interface (dashboard).
2.3 User characteristics
- Even though those specifics farmers in St Cassien are (former) engineer, we should assume no technical background from the users to be able to use this systems for others farms.
- Users are busy enough with their activity, we shouldn't assume they have time for complex deployment and maintenance.
2.4 General constraints
- The energy source : There is no power near of the greenhouse, consequently we'll use a battery.
- Duty Cycle : We can use only 1% of the time in order to comply with the law.
- Sensors needs to be moveable : Vehicles should be able to move along the greenhouse.
- Easy deployment : we aim to provide an easy way of setting up the systems :
- Via an easy sets of instructions (tutorial)
- And/or by using a docker image, containing all the necessary (dependencies and configurations).
2.5 Assumptions and dependencies
- We assume that the farm itself will have no (or not long) power outage.
- We assume that the battery will provide enough energy for a time span.
3.Specific requirements, covering 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.
3.1 Requirement X.Y.Z (in Structured Natural Language)
Function: Sensors' measures access.
Description: The farmer need to be able to view the measurements on a screen at any time.
Inputs: Measurements and data from the sensors (Humidity of air/soil and ambiant temperature).
Outputs: Visual graph on the screen, using graphana visualization.
Destination: Raspberry's InfluxDB
Non functional requirements: Acceptability / maintainability
Pre-condition: All equipments are powered and properly working.
Post-condition: Same state as pre-condition
Side-effects: None (visualization is a "passive" action)
4. Product evolution
In this iteration we aim to provide a local data viewer. Other groups are working towards an online dashboard solution. It might be interesting to group all this data on the same online virtual machine.
