APPLICATIONS OF MICROPROCESSORS IN INTRUDER DETECTION ARE DISCUSSED ON TERMS OF BOTH A BURGLAR ALARM SYSTEM AND A SIGNAL CLASSIFIER FOR USE IN RECOGNIZING THE TYPE OF INTRUDER.

Abstract

UNTIL RECENTLY THE COST OF PROGRAMMABLE DIGITAL PROCESSORS HAS BEEN RELATIVELY HIGH, AND THEIR USE IN INTRUSION DETECTION SYSTEMS HAS BEEN LARGELY CONFINED TO CENTRAL MONITORING STATIONS. THE ADVENT OF THE MICROPROCESSOR HAS RADICALLY CHANGED THIS PICTURE AND IS MAKING IT POSSIBLE TO APPLY COMPUTER TECHNOLOGY IN CONTROL UNITS AND EVEN IN INDIVIDUAL SENSORS. THIS PAPER EXPLORES SOME OF THE POSSIBLE APPLICATIONS BY DISCUSSING TWO MICROPROCESSOR-BASED DESIGNS FABRICATED AND TESTED BY GTE-SYLVANIA. ONE OF THE DESIGNS UTILIZES MICROPROCESSORS PRIMARILY FOR COMMUNICATIONS, STATUS MONITORING, AND CONTROL; IT IS TYPICAL OF MICROPROCESSOR APPLICATION IN CONTROL UNITS AND THE LIKE. THE SECOND DESIGN UTILIZES A MICROPROCESSOR FOR SIGNAL CLASSIFICATION; THIS DESIGN TYPIFIES THE USE OF THE MICROPROCESSOR, AS A DATA PROCESSOR, TO OBTAIN SUPERIOR FALSE-ALARM REJECTION AND TARGET CLASSIFICATION. THE DISCUSSION OF BOTH DESIGNS CENTERS ON THE ADVANTAGES OF THE MICROPROCESSOR-BASED REALIZATION AS OPPOSED TO MORE CONVENTIONAL DESIGNS. ATTENTION IS ALSO DEVOTED TO IMPORTANT PARAMETERS OF MICROPROCESSOR DESIGNS, SUCH AS MEMORY AND I/O REQUIREMENTS, PROCESSING TIMES, AND POWER REQUIREMENTS. ILLUSTRATIONS AND REFERENCES ARE INCLUDED.
