What is HACS?

Home Appliance Control System accessed by a remote device such as mobile phone or a palm-top to allow a home owner to control, monitor and coordinate home appliances.

Functional Requirements The heart of the home network is the control system written using J2EE with container

maintained persistence (retains history for one month). The central control system (CCS) shall provide secure login to the system. Users are identified

with a username and password. It shall accept instructions locally or remotely and communicate those instructions to the

appropriate devices within the home. Devices / appliances within the network shall have the capability to communicate between

themselves as necessary and coordinate their process activity. It shall allow the user to activate and deactivate the system. It shall allow the system to start, stop and display current status without interfering with normal

operations of the devices. It shall allow the user to add or remove, modify the behavior of and view the status of devices. It shall control, monitor, and coordinate appliances as programmed. It shall be adaptable. Detects events that change the environment and respond. It shall encapsulate lower-level functions to allow algorithms to vary independently. It shall accept information from the appliances, decisions made and appropriate messages

generated based upon the decision (i.e. alarms, notify home owner, dial 911).

Class Diagram of HACS A class diagram describes the static structure of the

symbols in your new system. It is a graphic presentation of the static view that

shows a collection of declarative (static) model elements, such as classes, types, and their contents and relationships.

Classes are arranged in hierarchies sharing common structure and behavior, and are associated with other classes

CRC Cards

A CRC card is an index card that is use to represent the responsibilities of classes and the interaction between the classes.

The cards are created through scenarios, based on the system requirements, that model the conceptual view of the system.

CRC Cards: How do you create them? Find Classes Find Responsibilities Define Collaborators Move the cards around

Activity Diagram

An activity diagram typically represents the invocation of an operation, a step in a business process, or an entire business process.

Activity Diagram: Configure Microwave

This activity diagram is a general representation for changing appliance/user configuration including adding new appliance/(s), removing existing appliance/(s), enabling/disabling appliance/(s)
