Generalized Maintenance Trainer Simulator: Development of Hardware and Software. Continuous real time monitoring of a distributed network of such devices, coupled with diagnostic expert system analysis thereof, permits capture and analysis of even intermittent failures, thereby facilitating maintenance of the monitored large-scale system. Retrofit capability of the sensors permits monitoring of even older devices having no built-in testing technology. Transparent interface of the sensors to the devices precludes operative interference with the distributed network.

A plurality of sensor implants may be rerofit to corresponding plural devices comprising a distributed large-scale system.

For example, monitoring of a computer-based device may include monitoring of parity error data therefrom, as well as monitoring power supply fluctuations therein, so that parity error and power supply anomaly data may be used to trace the failure origin to a particular plane or power supply within the computer-based device. Failure data is continuously obtained from predetermined critical points within the hardware device, and is analyzed with a diagnostic expert system, which isolates failure origin to a particular component within the hardware device. (Inventor)Ī remote maintenance monitoring system retrofits to a given hardware device with a sensor implant which gathers and captures failure data from the hardware device, without interfering with its operation. Maintenance of Automated Library Systems.ĮRIC Educational Resources Information Centerĭiscussion of the maintenance of both the software and hardware in an automated library system highlights maintenance by the vendor, contracts and costs, the maintenance log, downtime, and planning for trouble.
