Microcomputer system

Abstract

Abstract PURPOSE: To secure the continuation for the data transmission between the computers with no trouble by having a loop-type connection among plural number of computers and then giving the data transmission among two optional computers in case the connection control circuit has some fault. CONSTITUTION: When detector circuit 19 detects the fault of connection control circuit 18, control auxiliary circuit 21 gives the control to matrix switch 22 in place of connection circuit 14. And selector 31 switches the control signal source to switch 22 from circuit 18 to 21. If circuit 18 has some fault, a loop-type connection is given among microcomputers 10W13 to secure transmission of the data to computers 10W13 in sequence. And the data is transmitted between two optional computers among them. As a result, the continuous data transmission is ensured with no trouble among the computers and with the comparatively simple constitution of the circuit although some fault may occur in circuit 18.
