ENSC 151 - DIGITAL AND COMPUTER DESIGN LABORATORY

(ENSC 151 Final Project 99-1 Inst. Ljiljana Trajkovic)

Introduction

In a growing industrialized and commercial world, increasing crime rates are a natural consequence of the coexistence of diverse, and many times unbalanced, cultural and socio-economic groups which reside within that environment. The terrors which many people world-wide have experienced, home break-ins, are fast becoming a more common fear, and the subject of protecting one's family and personal possessions, to most, is a priority. In 1995, it was estimated that 2.19 million alarm systems were installed in the United States alone (http://www.securityresource.com/securitysales/factbook.html). Hence, the members of Unknown Talent for the past 3 months have been developing a prototype Alarm System (P-1.00), which we are hopeful one day might save someone's life, their confidence and even maybe their sanity.

Our security system monitors five different zones. Four of these zones are controlled by push buttons, which represent contact sensors that would be placed on doors and windows. The fifth zone will be controlled by a motion sensor. We will also add six buttons to our existing hardware in the form of a keypad. This keypad can be used in order to activate and deactivate the alarm system when a specific code is typed in. We will also make use of the audio port in order to output a sound if the alarm is tripped. The LCD on the EVB will display the status of the alarm system and will be updated in the event of a change in status. It will display whether the system is ready or armed as well as which zone a has been tripped (if any).
