CENTRALIZED MANAGEMENT SYSTEM IN BUS INTERFACE SYSTEM

摘要

The system comprises a computer (42) installing an address bus (4a), data bus (4b) and control bus (4c). A first-level station (4Q1) communicates with the computer, as the first level station is connected to the buses of the computer. A number of a second-level stations (4Q2,4Q3,....4QN) communicating with the first-level station as the second-level stations are connected to the first-level station through a multipoint bus (4r). The system is capable of communicating the computer with the first-level station through a dual port RAM, intercommunicating a number of second-level station through a mutipoint interface and multipoint bus. The system is economic and efficient.
