Background

Modeling and Simulation are central to the IoT Applications

...

and

...

employ a wide range of technologies and methodologies. Most of

...

these technologies focus on

...

rather specific

...

aspects and a

...

narrow purpose (e.g., discrete event simulation in industrial systems vs. continuous simulation in electrical and computer engineering). There is a need for an all-encompassing approach, especially in the IoT arena. Atomiton TQL provides right set of hooks to create an all-encompassing approach to simulation.

Greenhouse Problem Statement

For the purpose of this tutorial to explain implementation approaches to simulation we look at the Greenhouse monitoring system with following scenario.

Image Modified

For the purpose of this tutorial let's model the Greenhouse monitoring system with following configuration.

Greenhouse: size: 40 feet by 110 feet
crop types, tomatoes and peppers
3 lanes, each lane has 10 zones
Total 30 zones (each zone is 10 feet by 10 feet. Lay out is 3 by 10): 20 zones (2 by 10) are tomatoes, 10 zones are peppers

Each zone subdivided into 9 grids. Each grid is 3.33 feet by 3.33 feet. Total 270 grids

Zone Content:

1 temperature sensor (total 30)
1 humidity sensor (total 30)
1 camera (total 30)
1 irrigation motor (total 30)
1 heater (total 30)

Zone Grid Content:

1 ambient light sensor (total 270)
1 light (total 270)
1 irrigation nozzle (total 270)
1 soil moisture sensor (total 270)

External Conditions:

1 ambient light sensor
1 temperature sensor
1 humidity sensor

Simulation Design Patterns

...

The existing Atomic domain languages capabilities can be exploited to achieve simple to complex simulation. The simulation design patterns can be classified as follows:

...

Pattern #	Name	Description	Use Cases	Implementation Flow
1	@ThingFacet Level	Seamless integration within the attribute's associate action	Simple Sensors and Actuators	JavaScript to capture simulation logic Emulate automatic trigger for sensors
2	@ThingFacet Level	Separate Action to start the simulation	Simple Sensors and Actuators	JavaScript to capture simulation logic Schedule frequency of simulation
3	@Protocol Handler Level	Push the simulation logic down into protocol handler level	Complex simulation profiles can be passed Automatically available at the Invoke level	Within Protocol Handler.
4	@Behavior Tree	Simulation logic is driven primarily by Behavior Trees.	Simulate a behavior	Within BDL Facet Instance

Create DataModel to store non-thing related data

TQLEngine provides DataModel to store "pure" data, DataModels do not combine facets. They are simply models to store application data that is essential to create a meaningful real-world IoT application.

Simulating Temperature Sensor

Simulation Logic

Image Added

GHCurrentTemp is the general temperature inside the greenhouse
It is affected by CurrentTemp (external), the vent and fans, and all the heaters
The heaters are controlled by the application
The vent and fans controls are not exposed to the application. So vent and fan behavior are simulated by BT, described in the next section.
GHCurrentTemp is the default value for ZoneTemp if the heater is not on in that zone (if the heater is on in that zone, ZoneTemp will be higher than GHCurrentTemp)
Value updates every 5 minutes
GHTempAdj On Sunnyday: formula to calculate GHTempAdj in Celcius: GHTempAdj = (100/(CurrentTemp+237.1))³ * 100
For example, when (external) CurrenTemp = -5 Celcius, GHTempAdj = 5.186; when CurrentTemp = 28 Celcius, GHTempAdj = 3.661
On NOT Sunnyday: formula to calculate GHTempAdj in Celcius: GHTempAdj = (100/(CurrentTemp+237.1))³ * 60
For example, when (external) CurrenTemp = -5 Celcius, GHTempAdj = 3.111; when CurrentTemp = 28 Celcius, GHTempAdj = 2.197
Since temperature has an effect on humidity, always determine temperature value before determining humidity value

List of DataModels

Greenhouse : Overall DataModel holder for Greenhouse. GHLanes is defined of type reference. There are two types of references - simple reference and smart reference. Smartness can be defined by providing a "Find" Query at the time of model definition or at the time of instantiating the model. GHLanes is defined as Reference to include all the Lanes from Lane model.

Data + Things

We have to assign 1 temperature sensor per zone. We do this by:

Use the content of MultipleSensors tutorial project and bring in all the model content into this tutorial.
Use Simple Reference in TempSensorModel to a particular Zone using ZoneID
Other sensors and actuators can be referenced in a similar fashion.
