Abstract/Summary

The INTERRUPT-BASED ROOM AUTOMATION (IBRA) SYSTEM USING THE IBM PC/XT AS HOST is an intelligent system designed to automate the existing electronic appliances, lighting and security systems in a typical room environment. This will provide simple and convenient controlling services to facilitate the routine activities of an individual in a room. The IBRA System provides a network for the pool of addressable devices that can be controlled by the system using the IBM PC/XT. Its operation is fully interrupt-driven, avoiding the waste of dedicating the IBM PC/XT to a normally idle process. The system utilizes the services of the IBM PC/XT thru its hardware interrupt thus allowing users to make use of IBM PC/XT for other applications like word processors, spreadsheets, programming, graphics editors, user applications, games, and the like. These applications will be interrupted when control operations must be performed by the IBRA System, and will return to their previous state after the system relinquishes control. The IBRA System has the capability to automatically turn on or shut off the network pool of devices connected to it. Control can be done thru schedule, or directly using the Command System provided by the IBRA System. It also gives the user free access to control the devices directly thru the manual override feature and likewise, continue to monitor the state of these devices.

The IBRA System features simple detection of device malfunction of the network pool of devices through its feedback circuit, and can also detect malfunction of the IBRA System hardware circuitry itself which is considered a fatal error in the part of
