HOME-BASED AGED CARE HEALTH SERVICE SYSTEM FAULT TOLERANCE METHOD BASED ON DIGITAL FAMILY MIDDLEWARE

摘要

A home-based aged care health service system fault tolerance method based on digital family middleware. The method comprises the following steps: a home-based aged care service program on interactive service middleware sends a service request to an embedded operating system of a set-top box; a task manager of the embedded operating system distributes service process PIDs and sends application information to an isolating layer manager; the isolating layer manager establishes an isolating layer and starts a corresponding drive program; the isolating layer manager detects whether the drive program is normally started, if the drive program is normally started, transmits a corresponding control signal to bottom-layer hardware for response, and if starting of the program fails, sends fault information to a drive program isolating layer; and the drive program isolating layer reports the found fault information to a fault handling module in the interactive service middleware, and the fault handling module implements corresponding fault handling. Therefore, enhancement of the drive program of the home-based aged care health service system is effectively achieved, and real-time system fault detection and recovery are realized.
