1. Introduction
A home appliance control system (HACS) is a system which provides various services to remotely operate on home appliances, such as microwave oven, TV, and garage door etc through remote devices such as mobile phone, desktop and palm-top. This document furnishes the Use Case diagrams, Class diagrams, and Sequence diagrams for the Home Appliance Control System using UML.
2. Project Overview
The Home appliance control system is controlled either by a cell phone or a by palm top or by a PC. They are connected either through wireless application protocol (WAP), the Internet, or intranet. It controls various appliances such as a microwave, TV etc. The HACS system receives commands from remote devices that are manipulated by user. The system in turn dispatch commands to respective appliances that will perform the actions. HACS is responsible for keeping track of the states of the devices. If something goes wrong, it will notify the user by sending messages back to the remote devices as well as emergency department if necessary.
3. Functional Requirement
A home appliance control system (HACS) is a system which is controlled by a remote system such as a mobile phone or a palm-top, and at the same time controls, monitors and coordinates home appliances such as air conditioner, microwave oven, garage doors, TV set, VCR, audio controller, indoor/outdoor lights, water sprinkler, home security system, bath tub controller, etc.
In order to activate home appliances and to allow for different ways of cooking, the HACS needs mechanisms for communication between the different devices in the system, and for coordination among the various processes running on such devices
