Data communication systems at collieriesFunded under: ECSC-COALRES 7C
The problems of applying the emerging International Standards Organization/Open Systems Interconnection (ISO/OSI) international standards to the mining environment have been examined. The definition of standard application data protocols was accomplished by active participation in the formulation and review of ISO/OSI application layer standards. The requirements of the various installed and planned underground applications were considered in the formulation of a migration strategy to OSI. A number of constraints on the options open to the coal industry were taken into account. Other avenues were explored for protocols which could support a multihost internetworking environment. Communications of this type will be accomplished in the future by the emerging OSI standards, but in the interim Transmission Control Protocol/Internet Protocol (TCP/IP) is receiving wide acceptance in fulfilling this function. Sun's native networking architecture, Open Network Computing (ONC), was considered a more probable path for OSI migration. The introduction of standard data transmission systems makes it possible to interconnect almost all underground and surface equipment. However, without the adoption of standards for the higher layers of the ISO/OSI specification, this equipment cannot yet be integrated into a coherent network.
