Home Automation
Smart Lighting
• The purpose of the home automation system is to control the lights in a typical
home remotely using a web application.
• The system includes auto and manual modes. In auto mode, the system
measures the light in a room and switches on the light when it gets dark.
• In manual mode, the system provides the option of manually and remotely
switching on/off the light
Home Automation
Home Automation
Home Automation
• The Mode service is a RESTful web service that sets mode to auto or
manual (PUT request), or retrieves the current mode (GET request). The
mode is updated to/retrieved from the database.
• The State service is a RESTful web service that sets the light appliance
state to on/off (PUT request), or retrieves the current light state (GET
request).
• The state is updated to/retrieved from the status database.
Home Automation
Home Automation
• The devices and components used in this example are Raspberry Pi,
mini computer, LDR sensor and relay switch.
• When in auto mode, the controller service monitors the light level and
switches the light on/off and updates the status in the status database.
• When in manual mode, the controller service, retrieves the current
state from the database and switches the light on/off.
Home Automation
Smart Parking
• The purpose of a smart parking system is to detect the number of
empty parking slots and send the information over the Internet to smart
parking application back ends.
• These applications can be accessed by drivers from smart phones,
tablets or from in-car navigation systems.
• In smart parking, sensors are used for each parking slot, to detect
whether the slot is empty or occupied. This information is aggregated by
a local controller and then sent over the Internet to a server.
Smart Parking
Smart Parking
• The information model defines the attribute (state) of the parking slot
virtual entity with two possible values (empty or Occupied).
• The next step is to define the service specifications for the system. The
services are derived from the process specification and the information
model.
• The smart parking system has two services (1) a service that monitors
the parking slots (using ultrasonic sensors) and updates the status in a
database on the cloud (REST web service), (2) a service that retrieves
the current state of the parking slots
