Remote Maintenance Monitoring System Concentrator.

摘要

A Remote Maintenance Monitoring System (RMMS) concentrator has been designed, developed, and tested at the Federal Aviation Administration Technical Center. The concentrator is a microcomputer-based device that collects, stores, displays, and retransmits to a Maintenance Processor Subsystem, performance information obtained from many remote navigational aid monitors. The concentrator consists of a communications subsystem and a data subsystem. Due to its design features, the concentrator may be reconfigured to handle several RMMS tasks. By incorporating operating system software into the data subsystem, the concentrator becomes a low cost, general purpose minicomputer.
